Trouble With i7 920

post #1 of 13
Thread Starter 
For some reason, after having a stable OC for nearly a year my computer is randomly freezing.

I have already replaced my RAM and a new BIOS just came out for my MOBO and I haven't yet updated the BIOS.

Could that possibly be the problem?

If anymore information is needed I will maybe be able to gather it if my computer decides to not freeze at the BIOS.

Have a new 960 coming in the mail, but was looking to see if I could salvage my 920.

Any help would be appreciated.

Thanks,

Tomba

4.2GHz at 1.13v is pretty low. Freezing seems to be RAM related many times though, so I would give Memtest86+ a fair number of passes first. If everything checks out, I would imagine it's your Vcore. You have plenty of room to work with there.

I agree, 1.13v is incredibly low vcore for 4.2GHz, on a i7 920

I'd bump it to 1.20v and see if the problem remains.

Quick question, what does this mean?

Do you have 6Gb's of memory, or do you have 12Gb's of memory?

This could be the source of your trouble, if your QPI voltage is to low? (thats if you do have 12Gb's of memory?)

O wow, that's outdated and a typo.

At the time it was 1.31875.

Now it's 1.3875.

Also I have 12 gigs, yes.

The 6 sticks of ram is probably whats hurting you, take 3 out and see how stable it is, overclocks are sometimes more stable with fewer ram sticks.

Sorry for late update, haven't had a computer to post on seeing as it still freezes at the BIOS.

Also I have since changed out my RAM to the G.Skill F3-12800CL9T-6GBNQ (3 x 2 sticks of which I bought two packs to again be at 12 gigs of RAM) since I had a few bad memory sticks of my XMS3.

Could the problem I have be related to RAM again? I checked off on the RAM to make sure it was compatible with my motherboard (four times in fact before I hit order).

Could running the DRAM at 1.65 be pushing it too hard? Voltages on the pack (and as advertised on Newegg) were said to be 1.5.-1.6v. It's just odd because after I replaced the RAM it ran fine for a few months at nearly the same settings as my Corsair.

Any answers would be most excellent and I tried taking out a few sticks and no such luck in the unfreezing .

I'm not sure about the specific issue you're having, but one thing to note is that you usually can't just combine two sets of RAM and expect them to run at their advertised frequencies and timings. This is why you always see bigger sets have relatively higher timings.

Bump the timings up a notch or two, and see if any of your problems resolve.

Tried that, still freezing. Sorry about INCREDIBLY late reply, hard to get ahold of a computer around here.

I was also thinking could more voltage than the settings actually need be the problem possibly?

I was running 4.2 GHz HT/off at like 1.38. I know not all chips are built equally but it seems a bit high in comparison to other i7 920's running at 4.2.

Another interesting side-fact: CPU Temp displays my base clock (2.67 GHz) as running at near identical heat to my previous settings. Seems kinda weird.

IDk what this thread is about, but I too cannot get 4.2 ghz on my i7 and it sucks. Completely stable at 4 ghz though. I put my vcore all the way to 1.39 and it still wouldnt get stable. qpi at 1.45.
