Mixing memory speeds on Dell CPt 333GT works?

Q: Mixing memory speeds on Dell CPt 333GT works?


i have this dell cpt 333GT; it has one 128MB 100MHz module and i have another 128MB 66Mhz module too. Is it possible to mix both type of frecuencies in this models? i can put them both in there but suddenly it throws the blue screen of death saying that ther "might be a problem with ram maybe a speed mismatch etc etc etc" and its hex code. Can this two types of frecuencies 100 and 66 can be mixed in this models?

thanks in advance.

I recently got a buttload of computer parts from work. I have a working computer and a slightly ancient mobo - Asus P4S533 Anyway, I also got a bunch of memory as will. I have 1.2 gb of 333mhz and 1gb of ddr400 ram (in 2 sticks). I was able to boot up the computer with all the memory in.

My question is - what is the difference between all the speeds? Obviously the mobo supports all of them, so what is stopping me from running all of them at the same time? Is it better to run just the faster stuff with only 1GB? I'm not too terribly familiar with memory speed; I just want to make sure I won't blow something up...the computer was free, but I'd hate to bork it up. Thanks for all help

A:RAM question: mixing memory of different speeds

not sure, but i have a similar question. i am considering taking out the old ram chip from my parents old pc, its not much, but as long as its the same type of memory, would it hurt if i put it in just to add a little boost? i already have one gig of ddr2 ram

you can do that, but 2 gig and 512 mb mix is not very good, you should do either 1 gig + 512 mb or 2 gig + 1 gig.

A:mixing memory?

Why don't you return it. If you got the wrong memory, take it back and get PC3200. You can try overclocking your PC2700 to 200Mhz or you can set the bus speed divider for your memory so that all the ram is running at PC2700.

I have wintec ram right now can i get a 2gb x 2gb kit and use my old 1g x 1gb in ddr2 and still ahve increased performance?

A:Mixing memory capacities?

I personally always purchase as much RAM at the same time the computer is purchased that I think I would ever need, for example 4GB for a 32-bit computer and at least 8GB for a 64-bit computer.
That way they should be identical. Using a mixed RAM set normally doesn't work as there are so many variables, ECC, CL2, CL2.5 or CL3 PC3200 etc. And all RAM is not created equal.
lately i bought a high end workstation from a large manufacturer an it came with my extra RAM which was technically the same as they both had the same Item number. However, instead of 12GB of RAM I only ended up with 10GB, definitely a real bummer.

My gaming rig originally had 1GB of matched Corsair PC5400 XMS in it. I play WoW and needed more RAM due to severe chop in the game, so I could and additional 2GB of Corsair PC6400C4 XMS memory.

My question is, will I lose performance running both 5400 and 6400 together, or should I dump the 5400 and just run the 2GB of 6400?

I have no other machine to stick the 5400 in. I also ran 3D Mark 2005 both with all 3GB in and with only the 2GB of 6400 and had no noticeable performance difference on the score.

What do you think? Thank you for your feedback.

A:Mixing memory types

well, if you would've had 3gb of the 6400 ram it would've been best, but as for now, the situation is as follows: You either have 2Gb of the 6400 ram, which would be fastest(but you would have 2gb instead of 3) when you would insert the 5400, it would probably default to the slowest(in this case 5400) speed.(but you would have 3GB). As you said, it didn't have any noticeable performance difference. Therefore, I would just insert the complete 3gb. You could test the performance in a few games if you wish, see if it makes any difference at all.

A:Solved: Memory Mixing Problem

If you have tried all configs and none work then you're left with buying more of one kind of ram - ie 333mhz. It appears your Kingston is pc3200 400mhz and doesn't work with the 333mhz ram. Maybe you could sens it back and get the lower rated ram.

Hi, I am willing to buy additional memory for my PC. The PC specs are below. Currently I have 3x2GB 1333 and my question is can I add an additional 4GB in the fourth slot so it goes like 2GB 2GB 2GB 4GB? All 4 modules have the same timings and frequency but different size and brand. Will that work in full capacity?

A:Mixing RAM memory with different size and brand

Not in full capacity no, for starters your RAM won't be running in dual channel. It's always advisable to buy RAM in kits (2x2GB, 2x4GB, 4x4GB etc) as they're manufactured to work together perfectly. You can always try adding a 4GB stick but my advice would be just to buy a whole new kit, mismatched RAM can cuase issues.

but becuase Cas Lantency is different and also the make and model will this make much difference or will the performance of ram be reduced becuase of the slower CL....

Thx for any advice..

A:Mixing Memory Sticks good idea or not ?

I cannot read the language used in the link, however that looks like pc2700 or 333 ram not pc3200 or 400 ram.

If you are using dual channel, you most likely will not get the memory to run in DC. I will [probably] run ok. You may have to manually set your memory timings to CL3 so that all memory runs at the same timings.

In general I advise people not to mix memory if they want top performance and stability from their system.

I hepled a friend with a new build--the old computer is a Dell Dimenssion 4300S with a Pentium 1.4 Ghz processor--it runs very slow because it has only 256K Ram and is running XP. It has a capacity of 1 Gig.

So I have various upgrade options. I could just buy one stick of 256K and add it to the one open slot, but that would be mixing two different modules. I could also add two new 256Ks, or add a 512 to the existing, but then again have a mixing. I could of course add two 512s and have it maxed out. Price ranges between $25 to $120 with those various options.

She wants to keep this puter for a backup for the teens. What do you recommend? Willl 1 Gig make a big difference over 512? Should I put in new memory? Etc.

Mrning all,

Could any one tell me whether it would be ok to mix memory chip sizes on my mobo.

currently i have 4gb of ddr2 in one slot. would it be ok to add something like CORSAIR 4GB (2x2GB) XMS3 DDR3 1600MHz, in memory slots 2 and 3, leaving slot 4 free for when i can possibly afford another 4gb memory chip.

Will mixing ddr2 and ddr3 cause me a problem, or is it best to stick with ddr2 across the board?

Thanks in advance

Dear community,
I would like to max out the memory on my Dell precision by set of fours (8x4GB= 32gb or 4x4GB = 16GB and later upgrade to 32GB). The User manual says I have to match size, rank and organization of 2 or 4 modules. And of course FB-Dimm (currently 4x 1GB 2Rx8 are installed).
So far, no problem.
However, there are 4GB dual rank and quad rank modules around with different organizations, e.g.
- 2Rx8
- 4Rx4
- 2Rx4
I have read that the total number of ranks is limited by chipset/motherboard/CPU.
When I want to max out the memory per set of four (4x4GB =16GB and later another 4x4GB = 32GB), do I have to go with 2R modules? Or can I also use 4R modules? Or could I also mix them (e.g. 4x 4GB 4Rx4 and 4x 4GB 2Rx8)?
kind Regards,

I wanted to know if you can mix the speeds of DDR memory dimms for laptops?

I was getting blue screens of death ,hanging etc could this be linked to the both memory running at different speed, as I noticed that one is running at
266mhz and the other is 333mhz ?

The memory is from th same manufacturer and passes all diagnostic tests.

Read other 3 answers

Which is faster:
256mb 100 or 256mb 133?
What does the "100" and "133" represent?
Thanks in advance.

A:Memory speeds

100 or 133 is the rated speed that the memory will run at

100 mhz or 133 mhz

Then you can add CL to it

Believe it stands for case latency

CL 2 is better than CL3

But the memory only runs at the speed of the processor front side bus.

If you have a 100 mhz front side bus processor it doesn't matter if you put 100 or 133 in, it will still be running at 100.

Running 100 in a system with a 133 bus wouldn't work, very little pc100 memory will run at 133, it's just too fast for it to keep up

I'm going to be upgrading my motherboard and CPU shortly and the new MoBo supports (has slots for) both the older PC100/133 and the newer PC2100 DDR. My question is, how fast does the processor have to be before the memory becomes a performance "bottleneck"?

If I'm running a 1.5Ghz processor, will PC-100 be of adequate speed? Or should I go ahead and upgrade the memory chips to the newer PC2100? The board will support use of either/or, but not both kinds of chips at the same time.

A:Memory Speeds

DDR generates two bits of data per clock cycle, so it is actually processing data at twice the frequency it is operating at. DDR2 533 memory does NOT run at 533MHz - it runs at 266MHz. Your BIOS is giving you the DDR frequency (533MHz), while the software is showing you the actual frequency (266MHz).

A:Memory Speeds Problems with CPU-Z

I don't know if your Gigabyte board does it, but some Asus boards downclocked the memory when all four DIMMs lots were populated. That was done for stability.

The frequency, timings, and voltage for the RAM could still be set in the BIOS manually, to run it at its rated frequency. Sometimes, I've had to back off on the timing a little to get the rated frequency. It's like overclocking the RAM, even though it isn't actually being run at an elevated frequency.

If you adjust those setting, I recommend that you check the memory stability. The memory check at POST (power on self test) is inadequate; use the built-in Windows memory diagnostic, or a third-party tool like from:

Memtest86+ - Advanced Memory Diagnostic Tool

(Memtest86+ has the advantage of being OS independent.)

Windows 7 Fresh install results in slow internet speeds. Safe mode works.
A week ago, I upgraded my XP gaming box to a new video card (gForce 460), new RAM. I also bought windows 7 and did a fresh install. I formatted the drive that had xp on it and installed windows 7.

As soon as windows 7 was loaded I noticed the network slowness because it took forever to download the updates. I thought it was the fact that I hadn't installed the NIC drivers so I UPDATED THE NIC DRIVERS to the latest version.

When that didn't fix it I went in search for the cure. I googled and found people having similar problems and did everything anyone suggested. Here is a short list.

turned off auto-tuning
turned off IPv6
turned off homegroup
reinstalled drivers
uninstalled drivers (to get windows default drivers)
disabled many services to many to really list out.
turned off Windows defender and windows firewall.

Nothing worked. Finally I tried booting into safe mode with network. IT WORKED. The download speeds are normal in safemode.

So since it works in safe mode I am led to believe that it is a windows service that is causing the problem. So I play with disabling services that I think could be related and there is no change.

Finally I break down and decide that I will disable every services that isn't running after booting into safe mode and then I will add services back one by one until I find out that is killing my speed.

I do so but when I boot out of safe mode, I still h... Read more

6 months ago,i upgraded memory from the factory installed 64 to 256. It works,etc.

Is there any additional tweaking/ajustments i can do? i read something with virtual memory setting could be done for one thing.

A:After upgrading memory,its works,Virtual memory Tweaking Now?

Unless you have Win95 you likely donít want to go messing with your virtual memory. And even in that case it is the vcache you would be more interested in tweaking. Win98 and higher handles memory well.

If you watch your system monitor and are sure you arenít using your virtual memory you might do the ConservativeSwapfileUsage=1 INI tweak. Unless you are doing graphics, video editing or something RAM intensive you likely arenít using the virtual memory and the tweak wonít slow your computer. It doesnít speed it up, it just stops needless writes to the hard drive during idle time. Information if you want to do that: http://www.aumha.org/a/memmgmt.htm

Donít let anyone talk you into Cacheman or any of those Mem/RAM/Turbo/Boost type programs. They were written for Win95 and counterproductive in anything since.

was looking for some new RAM, as my computer's pretty slow. I found some for a good price, but had a question.

According to my specifications, by Data Bus Speed is 533 MHz, however my Memory Speed is 333 MHz. The RAM I'm looking at has a "speed" of 400 MHz.

First of all, what "speed" does this apply to? Data Bus Speed or Memory Speed? Second of all, does it matter? If my computer doesn't read it fast enough, is it incompatible, or just not as fast as it could be?

Thanks for your help!

A:RAM Question - Data Bus Speeds/Memory Speed

The 4600 is a sdram bored.
Do not get ddr, ddr2 or 3.
The speed of the ram is the speed at which the ram operates at.

To be honest your main bottleneck is the pc itself.
It falls under minimum requirements for windows 7, it will be slow and choppy at times.

Sorry I was inaccurate in my diagnosis.
Thank you Whest

I have a Pegatron Violet6 motherboard. There are four memory slots, and I have four 4-GB sticks of RAM.
I've been having a lot of BSODs lately, so I decided to test my RAM again.

Putting in one stick at a time and running memtest86+ gives:
Slot 1: All four sticks test okay and show 666 MHz (1333 MHz and 9-9-9-24)
Slot 2: All four sticks test okay and show 666 MHz
Slot 3: All four sticks test okay and show 400 MHz
Slot 4: All four sticks test okay and show 200 MHz (7-7-7-20)

If I put RAM in slots 1 and 2 and run memtest, it shows 666 MHz. But if I put something in slots 1, 2, and 3, I get 533 MHz.

Is my MB failing, or is this normal behavior? I'm currently only running with RAM in slots 1 and 2...is this going to work for a while, or should I be ordering a new motherboard?


A:memtest86+ showing different speeds for memory slots

I have never experienced readings like that, and can only guess as to what would cause it.

I tried looking for a motherboard manual with no luck. I thought there might be something in the RAM section about the slots that might explain it.

Installing RAM in odd combinations will toggle between dual channel and single channel mode but that should not change the speed. So it does not sound like anything normal.

You could be having trouble with voltage going to the slots. But even then I can't think of why that would knock the speed down.

Try running CPU-Z and see what it gives for RAM stats in different combinations.
You could populate all the slots and test it first.

Hello Dell community!
I was messing around with things and I ran GPU-Z and noticed that my GTX 1060 was Running at PCI-e x4 speeds instead of x16!

As you can see, the thing supports x16, but the card is only running at x4
Can someone help me fix this issue or at least tell me why this is happening?

A:Dell XPS 8700 GPU running at x4 Speeds

try running a load on the graphics card, and checking again.
spin up a quick run of Furmark or one of the Unigine tools like Valley or Heaven while GPU-Z is running and see what happens..
I can't remember, but GPU-Z might even have a stress button behind that question mark.pu

Hello. Lately, I've been growing more and more concerned over the slowness of my PC- it takes longer to boot up when it's been turned off than it used to, and programs take longer to open. It all seems realted to when the CPU Usage reported in Task Manager is up to 100%, which it is quite often lately, or the PF Usage, which is also often high.
Online speeds aren't any different, in fact since Firefox was updated recently they almost seem faster, but - if a site with lots of traffic or a page with many images, say, are trying to load, the browser might hang, or, AOL will say it's Re-connecting, and sometimes it signs off entirely. I cannot currently load videos because activating their loading causes AOL to sign off, and if a download is set to take longer than an hour or two , at some point AOL will need to re-connect and fail the download.
Also, in the past week there were three instances in which Windows gave the "Virtual Memory is Low" message, one of which when the PC was idle- connected to the Web but no one was using it.  I haven't gotten another one for about five days now, though.
I have a good amount of free space on the harddrive, and I have run Windows Cleanup and I just recently DeFragmented. Could these be virus symptoms?
