Not recognizing both ram slots

Q: Not recognizing both ram slots

My motherboard will support up to 2GB of pc2100 ddr ram. I currently have 2 X 256MB (512MB total :) ).

I recently tried to upgrade my ram. I was given 2 X 512MB pc3200 to try. I was told that it would most likely clock itself down to the pc2100.

I have only two slots for ram.

When I installed the "new" ram, system was still showing a total of 512MB, with slot 1 empty.

I checked and rechecked, switching slots, making sure that everything was nice and tight, and still slot 1 was always empty.

Then the wonder blue screen of death appeared. A little win32k.sys error. My BF freaked when he saw the physical memory dump counting up. I guess he expected the pc to blow up or something.

I was able to restart the computer and all was fine again, but still showing only 512MB and an empty slot 1.

Along with that, my McAfee crapped out on me. I was not able to repair the program.

So I stuck my 2 X 256MB back in. Slot 1 now was being recognized, and McAfee eventually repaired itself.

Is there something I'm missing here? Or is that ram just not for me?

Thanks ahead of time for the replies!

Preferred Solution: Not recognizing both ram slots

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.)

I recently bought 2 packs of 16GB G.SKILL Ripjaws X Series RAM from a person online. According to the seller, the RAM was going to be used in a build but the build was put off and the RAM was never used. Here is the link to the item details.
When I received the RAM and installed it (before you ask I made sure the RAM was seated correctly), my ASRock Z68 Pro3 Gen3 motherboard only recognized 16GB dual channel and not the whole 32GB. The RAM has run at 1600 MHz and is now running stable at 2133 MHz. The mobo supports up to 32GB.
I don't believe the RAM is bad, so excluding faulty memory, how would I get the mobo to recognize all four slots?
ETA: I believe the issues may lie in the configuration of the RAM. It may not be recognizing all the RAM because of dual channel. I'm not sure but if I could get someone's clarification on the matter I would really appreciate it.

A:ASRock motherboard not recognizing all four RAM slots

Disregard the post. Seller advertised the RAM as 4x8GB sticks but they were actually 4x4GB sticks.

I purchased a used Optiplex 7010 MT from ebay, but I am starting to wonder if there is a problem with the motherboard, specifically with one of the system memory channels. 
The PC came with a single Nanya brand RAM Module 4GB (DDR3-1600) DIMM located in the slot #2 position.
I tried to upgrade the RAM using some G.Skill Ripjaws X RAM (DDR3-1600), 4GB x 4, with all slots filled.
The PC will not post or even get to the PSA Diagnostics. Instead the Power button flashes 2,3 which indicates "system board, memory or CPU failure"
So I played around a bit, and I discovered that I can put ANY of the RAM in slots 2 or 4, and the Computer will post and runs fine, but if I put any RAM in slots 1 or 3, (with or without any RAM installed in slots 2 or 4) then I get the same error code, "system board, memory or CPU failure".
This tells me that my RAM is fine, since the system WILL recognize it in slots 2 & 4.
I even tried installing the Nanya RAM module in Slot 1 and in slot 3, by itself, and the error persists.
I have even tried upgrading the BIOS Firmware. It's currently running BIOS version A20, with no solution to the problem.
The system is currently function fine with 4GB RAM sticks in slots 2 & 4, for a total of 8GB, although when I check the BIOS status, it shows that the 8GB of RAM is in "Single Channel mode"
My question is:
Is my motherboard faulty, or is there some setting I need to select before my system will recognize the RAM in Sl... Read more

So let me start again First post here. I'm a programmer who doesn't meddle with pc parts. Well now has come the time!

I used the tool that Crucial provide on their website, which claims that my pc contains 2 pc133 slots and 1 pc100 slot (sdram).

It says I have max. capacity of 512mb. Will 2 256 pc133 sticks be ok? Or will performance default to pc100?

Also, what're the types of ram and will any other work with my pc? TIA.

Description: I want to attempt to use all 3 PCI slots by plugging in 3 different Nvidia GeForce FX 5200 graphics cards. I'm currently using 1 right now. I know all my specs are old as hell but my good computer is broken atm, however, I have a burning desire to play League of Legends and I've got no money to get my good computer diagnosed and repaired.

PC Specs:
[NOTE] Computer is from 2005 lol
250W Dell Powersupply
Nvidia GeForce FX 5200
Intel i915P/i915G Dell Chipset (Mobo)
2Gb Ram
3Ghz Processor

Question: So my question is, can I do it? Can I use all 3 PCI slots and plug in 3 Nvidia GeForce FX 5200, then editing some stuff in the BIOS. If this does work, will I need some special connector to use all 3 slots?

I'm worried that because there will be many useless VGA ports and etc, that it may cause problems if they're all not being used (like requiring a connector). Also, if I do end up using 3 graphics cards, will it even improve the quality of a game like league of legends?

Any help is greatly appreciated, thanks!

Try using a system diagnostic utility such as EVEREST or SiSoft Sandra. Both will say somewhere whether or not, and at the very least they will give you the model number of your motherboard which you can look up to find out if it has PCI-E or not.

Hey all,

What is generally considered better and why?

I'm considering a RAM upgrade to 16GB for my Asus Maximus Hero VI motherboard. It has 4 memory slots for dual channel. My local supplier only has the memory I want in 2x4GB modules. If I purchase 2 kits to make up the 16GB is this less preferable to rather waiting for a 2x8 kit to be ordered. Is there any disadvantage to using all 4 slots as opposed to 2? I will be over clocking using the standard XMP profile only.

Future upgrading is not a concern as I will not likely need to move beyond 16GB for the life of this build.


A:RAM 4 slots or 2?

In reality, it doesn't matter. Either one will net almost exactly the same performance.

However, if you want to get technical, if it's only dual channel, then you will get better performance using only 2 slots with 8GB in each. The more chips and slots that you use, the longer it takes to find the piece of data it needs. It's not going to be anything you actually can notice, but if you ran a benchmark you'd see a slightly better score with just 2 as 4 chips is slightly more taxing for the cpu.

4 slots used looks better than 2 though. If you care about aesthetics.

Is there any impact on the performance of a laptop under the following scenarios:

1) 6GB of toal RAM - 2GB in one slot and 4GB in another slot
2) 8GB of toal RAM - 4GB in one slot and 4GB in another slot.

(ofcourse 8GB is larger than 6GB ........... but ......... I cannot recall where exactly I read about accessing times of the CPU on symmetrically placed RAM modules and un-symmetrically placed ones - equal RAM in dual channel v/s unequal RAM in dual channel)

Any thoughts - if someone has a deeper understanding on this?

A:RAM slots

The 8 GB configuration would likely run in dual channel mode.

I'm not so sure about the 6 GB configuration.

But dual channel is not a major deal. The impact is minor.

I'd like to fill the other 3 slots of 3 x 2 Gigs for a total of 18 Gigs of Ram.

Is this possible? Both Ram are a different brand, but with the same specs essentially. Is it safe?

A:Using all six RAM slots?

It may or may not work and really no one can give you a definitive answer. What you need to do is install the ram then run some stability tests ie prime95 and memtest. If it passes ALL tests, then it should be fine.

I assume the ram in question is on the qvl list for your mb. If it is not on the qvl list, then you add a further variable to the issue.

You may want to try to update the bios:

What does it say in windows?

Your slot is 4x, the fast writing will be called that - look for it thru all the menus - a bios update may even add that.

lastly check that you actually got what you wanted - mistakes happen.

There might be an expander card that would allow you to double up, I'm not sure. Even if there is there is probably not enough physical space to do that. Maybe a "breakout" box? I'd check ask your local computer store and see.

I just put together a computer of my own using common household parts (OK, whatever I found laying around the house) and the motherboard I used was an old thing. Anyway, I've been trying to get an NVidia Riva TNT 16mb PCI graphics card to work, but every time I installed the drivers for it, it would totaly dork up my computer.

Eventually I noticed that the graphics cards requires a 2.1 PCI slot and my computer is only 2.0 PCI.

So, my question is, how can I update my computer (without buying a completely new motherboard) to 2.1 PCI slots, instead of 2.0 PCI slots?

Thanks for your help guys!

I have a Voodoo 3 3000AGP video card. It used to work perfectly, but ever since I had to have a shop reinstall Windows, it has not worked. I have tried reinstalling the drivers, but that has not helped. Whenever I go into games, they always have some kind of error when they are starting up. I never even get to see the title screens. The only thing I see is a gray screen and then my computer goes back to the desktop at 640X480 resolution rather than 800x600 which is what it is usually set to. Someone told me that I should make sure that the AGP slot on my motherboard is turned on, so I was wondering where I should go for that.

A Picture is worth a Thousand Words...Hmmm

I"m going to try to get it done in a couple hundred. You really don't need a picture. All these sockets point to the expansion slots in the back of the cabinet. They're all parallel to one another.
1. The PCI sockets are WHITE. about three inches long.
2. The PCI-E x 16 sockets are identical but they're BLACK, and they REVERSED in the board. (you'll see the anti-reversal bridge at the opposite end about 1 inch from the end. You can actually insert a PCI card into the PCI-E x 16 socket but the connectors will point toward the inside of the case. Not good.

3. The PCI-E x 1 sockets are also BLACK but only about 1 inch long.
Unless your computer has Add-in sound, Video, and Modem cards, most of these sockets will be empty.

If you simply must insist on a picture (or diagram) simply download the Motherboard manual from the manufacturer's web site.

Most of the motherboards out seem to have four slots for DDR ram. I have a board that supports 4 slots of DDR PC3200. Right now I have 1gig running in dual channel (2 x 512), but I need a lot more ram for some work-related programs I run that will easily use over 1gig. I am either going to buy 2 sticks of 512 or 2 sticks of 1gig. I have heard that in a lot of these AMD boards if you use all four slots it will reduce the rating from PC3200 to PC2700 and thus reduce performance. Is this problem caused by having 4gigs of memory (the maximum allowed) or is it caused by simply filling up all four slots regardless of the amount of total memory?

Thank you for the help...

A:Question about using all four RAM slots...

filling all four slots or installing all four gigs would force the chipset to relax the timings to improve stability. most people don't know it, but running 4 gigs of standard ddr ram (non-ecc) will not only lower performance but greatly decrease memory reliability. i say you should put two 1GB sticks in, giving you 2 GB of dual channel DDR400.

hi JoshuaRH97,
Welcome to the Forums.
Looking at this Y50 series specs sheet, this unit can take up to:
Memory 16GB max / PC3-12800 1600MHz DDR3L, non-parity, dual-channel capable, two 204-pin SO-DIMM sockets
The 4 memory slots is that the lenovo companion is detecting is likely the motherboard can support but physically, it only has two open slots.
As for the max RAM capacity, if you have the Intel Core i7-4710HQ CPU, the companion app is likely reading the max RAM that the memory controller can support (which is embedded on the CPU). Seing that the specs sheet above indicates 16GB as the max RAM, I recommend you stick to 16GB as this is likely the limit that the BIOS can support.
