Thread: Over timing Phenon II X4 920

So I have an AMD Phenom II X4 920 (2.8GHz) over clocked to 3.2GHz. I had it at 3.36GHz and it was running really well, never barged in or anything. I didn't tension it out other than gaming, but it wasn't 100% stable I don't think because I had to lower the O.C. to 3.2GHz to get it to fold. Any higher than 3.36GHz and it would not be unchanging and crash during gaming.

Anyway, I have just been modifying the bus frequencies; I think I have it set to like 235MHz right now to get my CPU to 3.2GHz. Anyway. Raising potentials will let me push the bus frequencies higher right? How just do I do this?

There are other voltages to consider as well. RAM, chipset, etc. Each of which grant you to push those elements are harder (and hotter).

Here's the thing, though: we don't know which part of your system was causing F@H to fail. When you force the bus, you're pushing the entire system. This is good, in the sense that it nets the most execution, but it also inserts the most points of failure.

At what speed is your RAM running? Is it within spec? If not, you may have to blow the RAM voltage or else. Or in increase to the CPU voltage.

You're entering the concerning part of over clocking. Anyone can bump their CPU a bit these days. But to fine tune your OC for upper limit performance and 100% constancy requires a lot of screening and patience.

I have 2x2GBs of G.Skill DDR2 1066 RAM. Presently they are coursing on an x4 multiplier, so they are really under their placed speeds, at 940 MHz so hopefully that won't be a determining factor when I begin pushing it more.

Yeah and thanks for the advice. I was intending to ask what I should use to stress test it, so Prime95 is good then. This all voices good, it seemed like I had enough of thermal overhead that I could use to find up the speeds, so I am hoping I get it up to 3.4 100% stable.

If your PC can run a full Prime95 test without losers, it is rock-strong.

Good luck! I'd offer more proposals but I don't know much about current AMD organizations ... so I can only offer general advice.

Yeah, just run Prime95. FYI, Prime95 doesn't end, so don't anticipate it to. Just run it for 24 hours, and if there are no errors, the OC is as static as it can get.

Ok, so I went into my BIOS and I can either set the voltages to manual or auto. They default at auto, and they say that in auto they will mechanically raise when over clocking. So do they just do a poor job of increasing the voltages, staying on the low end when it does it automatically? Or when it is static in auto mode going to be the highest I can get it on manual mode also?

Don't use auto! It does gain voltage as needed, but unfortunately it does this with no pertain as to the health of the processor. You could kill the Phenom without ever touching the voltage if you leave it on auto. Set it at the producer encouraged voltage and OC it from there.
