I have built 2 computers since the summer and I'm having some issues with a pair (or maybe just one) set of RAM modules. Basically the problem is that with the 2 memory modules inserted, I get random freezes, random display issues and crashes, some BSOD, etc. (mostly when I am gaming)
I have 2 of the exact same RAM modules, for a total of 8GB. The RAM modules which I am referring to are:
The reason why I am quite sure it's the RAM that is the issue (hopefully not defective) is that no matter which computer this set goes into, the problems occur. I have tried swapping in other computer parts (CPU, GPU, MOBO, HDDs, etc.) but nothing fixes. But when I try swapping in other RAM modules (ex. Corsair Vengeance), and the computer is OK...
To check the RAM modules, I tested them out with memtest86+ v.4.20, and they consistently (over 20 times) pass with 0 errors. I have tried different variations, testing each module separately, and testing them together.
I have wondered about sending them back to Corsair for replacements, but I am worried it won't be fixed and I will be wasting time and money (since the RAM might not even be defective). Also, I rather not buy a new set of RAM if I don't have to.
I have checked the Memory Qualified Vendor List and this is particular module is listed. (I think...)
I have checked the BIOS settings and ensured that all timings and voltages are correct.
Also, I am running Windows 7 Ultimate 64-bit.
Now, I am stuck. Am I doing something wrong? Is there any solution to help me fix or get by this problem?
Any help or ideas are appreciated,
Thanks in advance.
The voltage boost may indeed help. Also are you overclocking? Is the ram set to dual channel? Have you tried manually setting the ram to NOT be dual channel? Is this happening under load? Do you have memory fans? What is the ambient temp inside the case when it happens?
I don't know that memcheck would uncover either voltage or heat related issues.
1. I am not overclocking the system at all.
2. I have tried setting it with the automatic profile of the RAM, and I also remember doing it manually and making sure the setting was dual channel.... though, it never occurred to me that using it NOT in dual channel may yield different results.
3. Yes, this almost always happens under load (when playing games like COD)
4. No memory fans.
5. Ambient temperature is quite low, pretty 'cool'... nothing out of the ordinary.
Lastly, I didn't try the voltage increase route... I just sent one of the modules (the one I believe to be defective) back to Corsair for replacement. We'll see how things turn out... any suggestions if this doesn't work?
So from this, I learned that even though the RAM appear to be identical, they might not work TOGETHER unless they are from similar batches... hence, the reason why it's preferred to buy a RAM kit, if possible.
