Memory failure?

post #1 of 13
Thread Starter 
I have been fighting this seemingly stability issue with my overclock (or at least I think that is what it is). I have this random computer lockup (not just crash to desktop) while playing Fallout new vegas. At first I thought it is game related. I then played Torchlight for a while and dragon age for a while, although I did not lock while play those games, I noticed that at least 3 times I locked up doing something very mundane. Once while surfing, once while the computer was idle and once while installing a game. Since then, I backed my overclock to stock clocks and have running like that for a few days. So far so good. Problem is, the lockups are so random, it is hard to determine when this will happen. I am going to run stock for a week or two to see if I ever lockup again. But here is the kicker - with my overclock, I run gobs and gobs of test with OCCT, prime95 (total of 18 hours) and IBT (20 times twice) - and I do not get an error. I ran 4 hours of memtest as well with no error. And yet, mundane tasks locks me up randomly. I have a gut feeling my memory fails at overclock. My plan is to run for two weeks at stock - if no issues, then it is related to my overclock. In anticipation that it is my memory, I am wondering what I can do to alleviate the issue. I already got the timings at manufacture suggested (9-9-9-24-2T). The memory voltage is at auto, which relates to 1.68V (manufacture suggested is 1.5V - will this cause an issue?) My Vcore at 3.8GHz is 1.283V and Vtt is 1.238V. Someone here suggested that Vcore and Vtt should be within .05V of each other. Should I bump my Vtt a bit? Does it have any effect on memory?

On the overclock, did you disable CIE/ Speedstep?

try running linx with your OC on as it tests the CPU more and the memory less than something like Prime95 would then you can tell if its the OC. in some cases the over volt on the RAM could make it crash, manually set it to the manufacturers recommended in your case 1.5.

I disabled when I overclocked it. But once I overclocked and tested stable, I enabled them and re-tested with the same plethora of tests. The only thing I kept disabled was turbo boost. Should I keep them disabled?

Yes. Simply because when the CPU goes under the lower load of "mundane things", it will clock down and may cause it to be unstable.
Under those stress tests CIE and Speedstep aren't going to clock down the processor because they are always at 100% load.

Ok. I will try out linx and will set the memory voltage to 1.5V as well.

Can you educate me on how these would cause lockup? In my mind, the clock downs of CIE and Speedstep would be no different than at stock settings - unless I am totally missing something.

disable everything in the cpu features thing, with like speedstep or whatever in, only leave all the cores + hyper threading on (if u want hyper threading, IMO more stable with it off)
