I just want to see if anyone else would agree with my diagnosis of the memory problem I am having with my ram. Since I built my current gaming rig I have had issues with files being corrupt and random blue screens but they were never for anything that would seem related to the ram. I finally got fed up and downloaded Memtest+ 2.01 and tested my ram and it showed errors. So at that point I figured I would find which stick was bad. I tested each individual stick for 6 hours and both tested fine and when they were both in the system I would throw errors within 30 minutes and not make it through all the tests. At this point I re-ran the tests on the individual sticks in the other slot I was using and still didn't find anything wrong.

At this point I opened an RMA request to corsair to which they contacted me back saying that if the ram tests fine individually then it is a problem elsewhere, likely culprit being the motherboard in which they told me to verify the voltage, timings, speed, and that I am running the latest bios. I had already checked the first three items multiple times, voltage is at 2.1v timings are at 5-5-5-15 and speed is at 1066. So I updated the bios and retested both sticks together and got errors. I will mention at this point that I never get the same errors nor do the errors come up at the same time with the same amount.
So to continue troubleshooting and verify if it is the RAM or motherboard I took my ram over to a friends house who has the identical motherboard to me and the similar memory kit as me except he got the fan. Btw the ram I am running is the TWIN2X4096-8500C5D kit and he has the TWIN2X4096-8500C5DF. I installed my ram in his system and ran the tests and failed in his system without making it through a full sweep again. So we put his ram back in ran memtest and made it through the full suite with no errors. We noticed though after testing that my ram got considerably hotter then his did and we did not have the ram cooler installed at all.

So after all this I did finally get an RMA from corsair and upgraded it advance replacement, but They still wanted me to do more testing of the motherboard before I demanded a replacement. But my feeling on this problem is that the ram doesnt get too hot when running one stick but when running two of them and the fact they are side by side with no gap on my motherboard would get them too hot and things would go south.

So does anyone else agree with my final diagnosis or could it be two faulty motherboards or incompatibility oh and btw my ram and my friends ram were the exact same down to version numbers.

You need to raise the voltage on your NB.

Im using same exact RAM kits as you are and i had same issue as well. Raise the NB voltage.

Dont ask any more silly questions what is safe or not or why you should do it, just raise the NB voltage. Its a common thing that needs to be done.

Agreed but be nice. Usually, voltage increment by 0.02volts for the MCH and 0.1 for vtt is very safe.

I can't recall just yet, but will post when I get home this evening.

Ok I understand this but, Why on my friends computer with the same motherboard and same ram he didn't have to touch any of that and his ram is fully stable? And why would my ram get considerably hotter then his doing the same testing?

Im being nice.

OK, you didnt have ram cooler installed for one.

Second, no system is equal, no matter how you look at it, there will always be that little difference that will set two exact things apart.

Have you tried his RAM in your system?

Have you tried the other two RAM slots on your mobo?

Ok the ram cooler isn't installed on his ram, his ram is the same version as mine and even corsair said that the two sets should run around the same temps. Corsair also said the ram cooler is only needed for low airflow systems or when overclocking. I have tried his ram in my system and it works fine. and yes I have tried other ram slots on my motherboard. And now that I am home I have tried raising the NB voltage by .050 and I still failed miserably. Also in regards to the lack of the ram cooler, Mine didn't come with one and I have a 250MM fan on the side of my case that helps cool my motherboard and RAM. I understand you are being nice and I appreciate the feedback, but when you can tell by touch that there is a considerable difference in temperature between my set and my friend's set of ram then I think there is an issue. His barely got warm while running through Memtest, mine got Hot.

Those run Powerchips and shouldn't need additional cooling (provided your case has adequate ventilation).
Download Memset and give us a screenie of your settings: http://www.tweakers.fr/memset.html

Ok so I got my replacement RAM last week and I tested the new ram for 24 hours and it works perfectly. So as odd as it seems, I had a bad set of ram or for some reason they were not compatible with each other.
