I have some corsair 2x1024mb ddr2 800 4-4-4-12 ram that i'm using in a media center style case. Because of that air flow isn't great and there aren't many fans, however i've taken care to make sure cables are entirely out of the way. The cpu idles at ~30c, showing that at least it has enough air flow. The ram is a different story however. I realy have a couple of issues. First, i'm using the gigabyte p35 mobo, which doesn't let me specify a deffinite ram voltage. I can say how much i want to "overvoltage" it, but that starts at an unknown baseline that is, as far as i can tell, automatically adjusted based on who knows what. I made sure the speed and timings were correct in the bios, but i can't do too much else. I was having some issues with program stability so i ran memtest. I got a couple errors. I tried the sticks in another pc with a 680i chipset where i could set the voltages properly, and got no errors. That would seem to indicate that the p35 motherboard was the problem. However I ran a different set of ddr2 800 4-4-4-12 corsair ram on the p35 just to check, and they had no errors either. At that point i began to wonder if perhaps they were getting to hot. I put the original sticks back on the p35 mobo and underclocked them to ddr2 667 just to test my idea. After about a half hour i felt the base of the ram sticks, and they were to hot to touch for more than a second or two. That seems way to hot, and these were underclocked. At this point i'm wondering if its a mobo, heat, or ram issue.
