Asus P5KC and Core 2 Duo e6850: Not wanting to go higher than 3.5GHz?

[owntastic]

I've had this Asus P5KC for about a year and I've been very surprised with it. I've been running my e6800 at 500x7 (1333 for the RAM) for a while now and I've really had no complaints.

I haven't had any heat issues at all, so I've trid bumping the MHz a little, even by dropping the FSB and raising the multiplier. It seems as though no matter what I do, the CPU seems to top out around the 3.5MHz range even with different voltge settings.

The P5KC has some extra settings in the BIOS for CPU PLL, northbridge voltage, etc. but I haven't dared messed with those since I have no idea what to do.

My main question is, is it possible to push the e6800 chips higher than 3.5MHz on the nromal/high-end board or does it take a monster board to achieve this? Like I had said the heat isn't the issue, it just seems like it caps out at 3.5MHz.

Any help or suggestions would be greatly appreciated. Thanks a lot!

It may just be the CPU's limit. That's a pretty heavy overclock for a 65nm C2D chip.

Well, just another quick question. The computer will run fine at 500x7, but after about two days of being on on-stop, I'll get the generic blue screen with the memory dump count-down at the bottom of the screen.

Someone had told me that this could be a voltage issue. Do you think that raising the voltage might fix this problem? I'm actually completely satisfied with the speed that I had it at now, I'd just like it to be 100% stable which I really believe it can.

Edit: By voltage settings like I said above in this particular post, I meant possibly the northbridge voltage or something else besides the CPU voltage itself. Still, any suggestions are very welcome.

I've never pushed a 775 chip to 500FSB. I only went to 400FSB on my Q9300. My friend's Q8200, I've had up to 450FSB, but that was on an EP45-UD3R, which is like easy-peasy to 500FSB.

Do you think it might be wiser to lower that 500FSB to the mid 400s and possibly raise the multiplier to 8 or so and see what happens?

I was so surprised that I could hit to 500FSB on this board and then have it run sem-stable for a few days, but I can just can't live with the fact that it's not rock-solid.

From my understanding, the higher the FSB, the more performance (in lack of a better term) you get from the processor. That's what hitting the 500MHz mark was so astounding to me.

If I lower the FSB to the 400s and raise the multiplier, am I going to lose any type of performace in my gmes and visual software in Windows? That's truly my main concern when it comes to lower the FSB.

I really appreicate your responses, thank you so much.
