Can't get over 3.5 GHz. with an E6700

post #1 of 7
Thread Starter 
All,

I have been experimenting, and 3.5 GHz. is the highest OC that I have been able to achieve so-far.

When I attempt to go higher my pc will not re-start, do you think that I should increase the voltages more?

I think your getting pretty damned close to your limit. I personally dont think you should go much higher, even though the core 2's will take it.

You could do, but keep it under 60 at all costs.

TAT temps? those can go a whole bit higher than 60C. The absolute limit is 85C, but it is advisable to stay lower. 60C is a very safe limit, but 65C is very reasonable also.

I know sdumper ran his at 71C IDLE(!) and had no ill effects (ok, short run)

I think you can bump that northbridge temp up a bit... try playing with that a little

53C Load is very good... that's definately not a problem.

I just took the northbridge to 1.55v and the CPU to 1.55v.

I set the FSB to 395 x 9 = 3555 MHz.

The system booted into Windows for about 4 or 5 minutes, temps seemeed to be ok, but the system went to blue screen and I had to do a re-start

My system just dosn't seem to like anything over 3.5 GHz. and it's not the temps. I think that it might be the memory that can't handle it?

Um, what are you running your memory at? You have 800 speed RAM and at 395FSB, a 1:1 ratio would be basically the stock speed for the RAM. If your RAM can't run at stock, you should send it back.

edit: and you are giving your RAM 2.25v......shouldn't need that much voltage for that RAM to run at 800 speeds.....

just a thought, unless i saw it wrong in your picture, you are only running one instance of prime95, thus using only a little over 50% cpu, your temps would be around 60 if you run it at max.

i suggest not bumping up your vCore anymore, but you might be able to pump up that NB vCore to 1.65v to get more stability if your mobo is running cool right now.
