Memory modules upgrade on ThinkPad P51

Q: Memory modules upgrade on ThinkPad P51

Currently I am trying to upgrade memory modules on my ThinkPad P51 of type 20HH. It was planned to have maximum, i.e. 64 GB, instead of original 8 GB. After some research four of Crucial 16 GB DDR4-2400 SODIMM CT16G4SFD824A have been obtained. With absolutely no problems two of them have been inserted in slots under the bottom cover. On that stage the laptop starts up and works perfectly with total 40 GB of RAM consisted of new 32 GB and original 8 GB. However, after adding a new memory module under the keyboard and/or replacing original 8 GB memory module with new 16 GB, and/or even putting original 8 GB memory module in the neighbouring slot, the laptop doesn't start up. Several attempts have been done to solve this problem, i.e. BIOS has been updated to 1.47 version, CMOS battery has been removed and returned back to its place, SSD drive has been removed and returned back to its place, the laptop has been turned on with a battery only, with AC power adapter only and with both of them. Nothing of the listed above helped to solve a problem. Did someone face the same problem? Is there a solution for it?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hiyas, I recently purchased 3rd party memory (https://www.amazon.com/gp/product/B07H4XNNXK/) that matches this computers specs, but the computer powers on and sits at a black screen.  I then purchased "compatible" memory, according to both Crucial's website and Amazon's website: https://www.crucial.com/usa/en/thinkpad-t490/CT14628403 https://www.amazon.com/gp/product/B019FRBHZ0/but this is also booting to a black screen. I talked to Lenovo tehnical support who told me I have to buy a module from the Lenovo store. They're $350 there. Does anyone know of any third-party 16gb modules that work in this laptop for the normal price of around $100?

hello, I hope this is the right place to ask some Q about the IBM thinkpad G40 .. My son bought a second hand G40 some years back. It had/has only 256M memory. Now I want to upgrade the memory and I scanned the relevant web pages of Lenovo. Apparently the memory should be PC2100 or maybe PC2700 becasue of PC2100 availability ? (DDR)Now a cpu-z run on that laptop says the memory is PC2300 (142Mhz) so what gives ? Has this been put in to be on the safe side or ?and an additional Q .. can memory modules be mixed ? ie can I add a 512M PC2100 sodimm to get 768M ? or do I need to remove the original 256M and go for 2x 512M ?TIAImbsysop

A:Thinkpad G40 memory upgrade

Welcome to the forum! Your machine can run PC2100/2700 memory, and you can combine it, it will always run at PC2100 speed regardless of anything else. It can be mixed, no questions asked. If the G40 is Celeron powered, it will take up to 1Gb (2x512Mb) of RAM. If it's Pentium 4-powered, you can install up to 2Gb of RAM. Hope this helps.

Howdy All! I just ordered a Thinkpad P70 with a XEON 1505-M processor. It comes with one 16gb ECC memory module. I want to add 3 more and when I checked Crucial.com's memory upgrade options, it only list 1x16GB NON-ECC memory modules! So two questions: 1) Can I mix the 1x16GB ECC memory module with 3 NON-ECC 1x16 modules? 2) How hard is it to install memory in the P70? My last couple of mobile workstations have been Dell M Precisions and adding memory was EASY (no need to remove the keyboard ,etc)! Thanks in advance! Aggie85

My last couple of mobile workstations have been Dell M Precisions and adding memory was EASY (no need to remove the keyboard ,etc)!About 1: It might be possible to mix ECC with non-ECC modules, but you would lose the error detection on all modules then. Since non-ECC modules are only slightly cheaper I would not recommend it. About 2: for the P50 it is a piece of cake to install memory, it should be no different on the P70.  As for memory: Lenovo currently uses Samsung modules. So if you want to go for the same 16GB ECC modules check for M474A2K43BB1-CPB. I do not know about Cruicial, but at least Transcend also got 16GB ECC modules (check for TS2GSH72V1B). I cannot say anything about the Transcend modules, but I installed two of the 16GB Samsung modules (besides the 8GB module that was already in) in my P50 had no problem so far (even checked with Memtest86+ for a whole night). Cubbi

The current configuration of my system (as bought) is 4Gb RAM.  According to the specifictions, it is upgradable to 8Gb.  I had a conversation with Sales Support via Chat trying to find the correct part number for 8Gb memory to replace the 4Gb.  I was told that as my system is still under warranty, I would need to contact Technical Support for this to happen.  Having done a number of searches on this forum, would I be right in suspecting that the existing 4Gb is soldered in to place - hence the need for a Warranty call to upgrade.  I was advised that any attempt to make the change myself would void the warranty.Any thoughts please.

I know that the L520 allows a maximum memory of 8 GB. Do I have to use each slot to get maximun memory (4 + 4) or can I install a single 8 GB stick into a single slot and leave the other empty? If I can use the 8 + 0 method, does it make any difference as to which slot I install the stick? Additionally, does it make any difference in speed if I use the PC3-10600 memory or PC-12800 memory? i7 - 2620M processor

A:ThinkPad L520 RAM Memory Upgrade / Installation

I'm of the opinion a L520 will support 16GB, at least my T520 and both X220 I have do so. And they're the same generation as yours
 
Generally speaking it's better to have two sticks for dual channel, 2x 4GB should be better than 1x 8GB. Although the difference may not be so noticeable in normal daily usage.

Thanks all.

From the parts list of the Maintenance Manual - your computer will only accept 4gb modules.  If you only have one socket on the motherboard, you are limited to a single 4gb stick.  Usually the system has the option for two memory modules, so I would suggest contacting Lenovo support by phone to discuss this situation.

Hi This is my first post to the forum. Regrettably I must start with a problem. Following suggestions on this forum I decided to upgrade RAM in my X200 to 8 GB. I bought 2 4GB chips branded by G.Skill http://www.gskill.com/en/product/f3-1600c11d-8gsl I was very disappointed to find the memory doesn't work. The machine won't start (black screen) with several pipping sounds.I suppose they mean DIMM problem. When I replaced the original memory chips everything is normal. Is this at all impossible and I should go for another memory ?Could possibly BIOS upgrade help ? I'd be very grateful for any comments and suggestions. Cheers,Chris

A:Thinkpad X200 memory upgrade failure

Welcome to the forum!
 
Unfortunately X200's are very picky with DDR3-12800 (DDR3-1600) like the ones you bought.
 
I would advice to buy DDR3-10600 (DDR3-1333) or DDR3-8500 (DDR3-1066) RAM. I would also recommend you to avoid the "Value RAM" line from Kingston, the "Value Select" line from Corsair (other lines from those brands are ok) and any no-name brand from eBay and similar shops.

Hey Lenovo Enthusiasts! I am about to purchase the Lenovo Thinkpad 550s, and I am tempted to purchase the baseline memory (4GB) and storage (512GB) HDD.  I want to make sure that I can indeed upgrade the memory to 16GB of RAM and the storage to a 256 (or 512) GB SSD. In my research earlier on, I noticed that somebody had posted a link to the parts list:https://download.lenovo.com/parts/ThinkPad/w550s_frubom_20150130.pdf I don't know what half of this technical jargon is, but from what I gather, I have found an SSD made by Samsung on Amazon, and an 8GB memory made by Data Memory Systems that seem to abide. SSD:http://www.amazon.com/Samsung-256GB-2-5-Inch-Internal-MZ-7KE256BW/dp/B00LMXBOP4 Memory:http://www.datamemorysystems.com/parts/lenovo/03X6657/ Questions:1) Could somebody wiser than me please verify that these products will work for the w550s? I was going to purchase them from Crucial, as they say that is is "100% compatible" but I am not sure still.Crucial: http://www.crucial.com/usa/en/compatible-upgrade-for/Lenovo/thinkpad-w550s 2) In regards to the warranty, does anyone know if I were to mess up the data preloaded on the HDD that is put in the laptop, by trying to transfer it to the SSD, would the warranty cover fixing this? Kind regards,Spencer

A:Lenovo Thinkpad W550s Memory upgrade to 16GB and S...

Very disappointing. Yes, I have the same problem (son, since it is your problem!). I note that over 189 people have at least looked at this question you asked before we decided to have you purchase the W550S...and after calling tech support one last time after my son purchased the machine (and was told there should be no issue)-we see BSOD multiple times within an hour.  They happen so quickly that it is hard to even note what the error message is.... I replaced his 512 HD with Samsung SSD 512GB drive. I used a disk duplicator-everything seemed to go great. Then I put in 16GB of RAM-again, everything seemed great. However, the notebook is only now being used frequently as my son is starting school now-and as said above, the BSOD is making me think this has something to do with the SSD or RAM replacement. Yes, obviously, it's fairly easy to replace with the original parts and see if the problem goes away-but he wanted the SSD and more RAM, so even if that fixes the issue-we will likely get rid of the notebook. BUT:  here is what disappoints me:  absolutely no comment on my son's original questions. I'm guessing I won't get input from Lenovo either....will try to call tomorrow, but we are almost beyond the point where we need to return the SSD/RAM and notebook if we want our money back. A little guidance from Lenovo would be appreicated before we need to make a decision.. Thanks,Steve

Go here and allow the Crucial System Scanner to load and run.

After the scan is finished and a report is displayed, copy-and-paste the webpage address to that report here so we can go there and view it.

------------------------------------------------------------------

If the motherboard is designed for DDR333/266 modules, it'll probably accept and run with DDR400 modules, but they'll run at the slower speed that the motherboard supports.

-----------------------------------------------------------------

The larger the number, the faster the speed.

DDR400 is DDR PC3200(400 MHz)

DDR333 is DDR PC2700(333 MHz)

DDR266 is DDR PC2100(266 MHz)

I have just bought a load of 128 MB RAM and 256 MB RAM modules to upgrade a number of PCs ranging from 450 MHz P3 to 933 MHz P3.

The modules were specified as 100MHz SDRAM DIMMS, and although most of the PCs were non-branded, I was able to check the motherboard details and according to all the specs, there was no reason why these memory modules should not have been OK.

However, with the exception of one 600 MHz P3, none of the other PCs accepted the memory correctly - they all registered exactly half of the actual memory on the module.

I have heard of problems where double-sided modules would only register half their memory, but in this case all the modules were single sided. (I did not order them as single sided, they just came like that even though the spec was 16x64 for the 128MB and 32x64 for the 256MB which suggests double-sided to me.)

Where is the problem and how can I make sure I get memory that works properly?

Thanks.
 

A:Memory modules

Many new memory modules cause that problem. The issue is the addressability of the individual chips. The fewer number of actual physical memory chips the module has, the newer the memory support chipset on the MB needs to be to properly address all the memory. The address lines from the individual chips come directly to the module interface connection, and the MB has to be designed to use them. Some omit the high-order address lines to save money, and as a result they only address half the memory. I've personally traded several people older modules for new ones to solve this issue for them, it's quite common.

http://www.orcalogic.co.uk/asp/prodtype.asp?prodtype=26119&ft=m&st=3

It says that you could use the DDR2 533MHz (PC2-4200) 200-PIN SODIMM memory modules and you could upgrade the memory up to 2GB RAM

I was given an IBM PC300GL Model 6561 with a monitor on the weekend. I upgraded the HD from a 3228mb to 6449mb out of a similar machine. The upgraded drive has Win98 SE. Also added a 10/100 DLink NIC. Both installed ok. The issue with this is the memory. It hade 32mb dimm NP in it and gave a #164 parity error for the get go. In researching the IBM web site I found all the specs and the Mem chart is under the cover as well. I have 2 - 32mb modules at 66mHZ, 1 - 128mb PC133. I also tried 2 - 64mb PC100 dimms with no luck as well. At one point the 2 - 32mb modules worked and I was able to install all of the hardware it found. After setting up the video and having to reboot the parity error came back? I have tried all of the appropriate combinations of memory and all I get now is an a 2 beep parity error and then System Halted. There is a BIOS upgrade available that I have downloaded but not yet tried. Is that worth a try? Any suggestions are welcome.

 Hello Forgive my status as a technoramus, roll your eyes as necessary, then please skinny me on what I need to know to increase the 2G memory for my G550 laptop. Depending on price, I may go as high as 8G, but 4G or 6G are options, as well. So, what's compatible, and can I simply add to the existing 2G, or do I need to replace that module? Much obliged

A few memory module questions:

1) Given a memory module with timing of 5-5-5, is that otherwise known as Cas Latency 5? Is 6-6-6 Cas Latency 6?

2) Which of the two is more performance oriented?

3) Some mobos I am looking at on newegg.com bear the requirement "Only DDR2-800 memory supporting JEDEC approved 1.8V operating with timings of 5-5-5 or 6-6-6 is supported on Intel Desktop Boards based on Intel 965 Express Chipsets." In this instance, "Intel Desktop Boards" are those from Abit or Asus that accommodate Intel CPUs.

Is it sufficient to find DDR2-800 5-5-5 modules running 1.8V or is the JEDEC seal of approval also mandatory?

4) Is 1.8V synonymous with JEDEC?

Thanks.

Assuming you have a working system, you should try 4AllMemory and use their [Check My System] applet.

The applet will return a list with the exact specs for the DIMMs you need to match your system/motherboard.

Note I am not saying you need to buy from them, but their applet is really neat.

Hello,

I recently added some extra memory to my PC. My local superstore advised me that the unit they sold me was the same as the one already installed. This seems to be not so.

I ran SiSoftware Sandra and noticed the following differences in
'Speed' and in 'Set Timings'

Memory Module 1 >

Serial Number: 050805C3
Type: 512MB DDR-SDRAM
Technology: 16x(32Mx8)
Speed: PC3200U 2.5-3-3-8
Date of Manufacture: 25 December 1999
Set Timing @ 200MHz: 3.0-3-3-8
Set Timing @ 200MHz: 2.5-3-3-8

< Memory Module 2 >
Manufacturer: Dialog
Type: 512MB DDR-SDRAM
Technology: 16x(32Mx8)
Speed: PC3200U 2.5-4-4-8
Version: 1.0
Date of Manufacture: 25 December 1999
Set Timing @ 200MHz: 2.5-4-4-8

Can you please advise me if the differences damage performance and if so is there any way of rectifying the problem or do I need a new chip. If so which one of the above is the better performer

Thanks in advance.

My ZBook came with 2x4 GB memory modules and I want to upgrade with additional 2x8 GB. It is the same manufacturer and specifications, only the size is different. There are four memory module slots, how do I put the memory modules for best performance? Maybe: 8 GB in slot 1 and 3, 4 GB in slot 2 and 4

I have the Zbook 15 G3...very similar if not the same motherboard. I have 2 x 8 gig in slots 1 and 3 and it runs in dual channel so I would say put the 4 gig pair in slots 2 and 4.

My motherboard is a Z77 Asrok Extreme 6.

It has four dimm slots. I have One kit of 8 gigabyte memory from Gskill that is DDR3. 'dual channel' (11-11-11-28) PC 2133.

If I get another kit of 8 gig from ANOTHER vendor and its different timings can I put them into the alternate slots and have it work? Say I buy Corsair (9-9-9-9) PC 1600. Would the two kits work against each other since they are different timings? Is this NOT recommended?


Here is another better question. What if I buy the exact same memory from Gskill and drop them in as well? So I have two kits of dual channel 8 gig ram for a total of 16 gigs. Both kits would be same type/speed and latency. Will this work or do I need to use 'quad channel'?

Edited for spelling.

I'm thinking that different timings will cause issues with Dual Channel functionality. I'm also thinking that Dual Channel only functions if all modules can operate in dual mode. If you are not planning on operating in Dual Channel mode, I don't think it matters. However the modules should operate with the same timing, if they are to be linked together.

Anyway without actually knowing for sure, those are my thoughts.

Hello, i own a xw8400 and want to use 4x8GB memory modules. I bought 64GB (8x8GB) DDR2 FB Fully Buffered PC2-5300F 667 Memory and they are accepted by the system. But - after some time the computer goes down / is switched off. There's no bluescreen or other hint helping to find the cause. The machine is switching of like pulling the power cord. At first i thought it might be a cooling problem. So i checked the temperature and it seems to be in regular limits (about 28-30C air temperature). I found info in the web, that 32 GB on that machine (2 CPU) should only be possible with a riser card (8x4GB). On the other hand it might only be a result of the fact that 8GB modules were not available at this time.I have two questions: * Is it possible to use 8GB modules on a xw8400 system with 2 CPU?* i am currently testing the modules with memcheck but is there any way to get diagnostic information why the system is shutting down?Thx G.

A:8GB Memory Modules for xw8400 / xw8600?

This might relate.  I have not confirmed this but I believe the memory controller on the xw8400 is the same as on the xw6400.   I noted for a prior project that HP officially supported specific 8GB sticks in the xw8600, and that the xw6600 and xw8600 memory controllers were the same.  That gave me the idea that perhaps, though not documented, those same sticks for the xw8600 could work properly in the xw6600. I got some of those HP 8GB sticks and confirmed that they would run in my xw6600 builds just fine.  But, they would not run in my xw6400 builds.... same sticks, same perfectly functioning workstations if they had HP 4GB sticks in place. I believe you are running into a memory controller issue on that older generation xw8400 workstation..... the earlier (6400/8400) and later (6600/8600) generation workstation familes I note above have different memory controller chipsets.

Hi,

I'm really hoping that someone can point me in the right direction to solve the problem I'm having trying to upgrade the memory in my wife's computer. I've ordered and received a matching pair of 512MB memory modules from Crucial to replace the existing single 512MB memory module.

The problem is that the PC freezes when both the memory modules are installed at the same time (the Intel logo of the motherboard does not appear, so I don't get change to visit the BIOS configuration screen and there are no beep codes). Both of the new memory modules work fine when installed in isolation.

Interestingly, the PC does boot OK with 1GB if I have the old memory module and either of the new memory modules installed, but only in single channel mode. The PC (eMachines e3042) is based on an Intel D102GGC2 motherboard which should support double data rate.

The m/b has been updated to the latest BIOS version, and I've tried using a higher power PSU (the original was only rated at 288W) and installing a dedicated graphics card (previously relying on the shared-memory ATI graphics on the motherboard). Neither of these helped.

I'd really appreciate any ideas on what I should try doing next.

The memory should work but memory compatible is never a sure thing unless you buy exact sticks tested for a specific system, but chances are that they'll work.

Upon opening up a Dell Dimension 8100 for non-bootup problems I realize this animal has these memory modules with heat spreaders.

When checking on pricing on these modules, one online memory shop indicates that these particular modules MR16R1628AFO-CK8 800-45 memory modules have been discontinued. Other sites seem to be selling them as normal inventory.

These modules are the 184-pin RDRAM modules not the 232-pin modules. Are these modules prone to keeping a Dell from booting up?

When troubleshooting this Dell computer I unplugged everything from the mobo up to and including swapping power supplies with no luck in the computer even powering up (the CPU fan doesn't come on at all). I even swapped out the Pentium 4 CPU with another and still no boot up.

While searching the internet for an answer, I found this one Google item from another forum indicating this exact memory module failing and not being able to boot up the computer. Are these memory modules that tempermental? I read that these modules must be installed in matched pairs.

For this particular job I'm thinking either the memory module(s) may have gone bad, the mobo went south, or the BIOS is dead (replaced the battery with no change). Before I end up ordering another mobo I'd like to know if the problem could be the memory modules going bad.

Thanks,

Craig

RD RAM = complete nightmare. I'd suggest it would be cheaper to get an entire new AMD system (MOBO, memory and processor) rather than trying to get more RD RAM, especially as you'll have to buy a pair of RD modules as they don't work singly.
