I got that too several times just now while I was trying to get a better OC. Somehow the board doesn't like certain FSBs at all - if you're lucky it will just give you a "POST failed" message, so you can get back into the BIOS and change it, but sometimes you get that screen. When that happens I found no other way but to reset the BIOS (which is damned annoying). I gave up further overclocking after having to do that three times in a row.

Since we both have the same CPU, here are my OC values for you to try:

FSB @ 1200 (really 300), 9x multiplyer - giving me 2,7Ghz.
RAM at stock 800Mhz giving me a 3:4 ratio.

No VCore change needed.


I was really hoping to get to 400x9 = 3,2Ghz for a 1:1 ratio but that gave me the same problem you're getting. If anyone knows how to avoid getting that screen I would appreciate it too.

Yeah I got that too, ussually around the 405-425 FSB region. Just pop the CMOS battery out and shut the psu off for a second is all it takes to fix mine and keep going.

Also maddogx, 400x9 = 3.6 lol, either wrong multi or bad math.

Mines running 400x9 = 3.2ghz, ram at 800mhz, vcore at 1.37V, but 1.32V after vdroop under load (going to pencil mod it soon i swear), NB at 1.3 V.

Ok, so I know it will depend on the CPU I get. But is the price spent on a new C2D going to be worth the performance boost? What kind of performance boost am I looking at, 10-15%?

Well it depends, are you going to overclock the C2D ... if you overclock it to ~3ghz, which is fairly easy for any C2D, you will see a significant boost in basically everything.

400*9=3600; 400*8=3200. Maddog's math is correct.

Clock for clock the C2D delivers 2x the processing power of the pentium predecessor....i.e. a 2.8GHz C2D chip will deliver twice the performance of a pendtium D920 or D820.

hm? no i was just bugging him in his post he says 400*9 = 3,2ghz

hey guys, 2 quick questions....

Just purchased the p5n-e because of all the amazing review about it for OCing and such.

Only afterwards did i start reading all the problems with OCing a q6600 on it. I haven't purchased the processor yet, but was still planning on buying a q6600. With the future games taking advantage of quad cores, is it still worthwhile to buy the q6600? Or should I only stick with a c2d since they are better for OCing. (Only doing air cooling here).

Secondly, I already have a BFG 8800gts 640mb OC2 card, and was looking at getting a second one for SLI. Would I be able to SLI a BFG 8800gts 320mb card with the 640mb card? Just looking to save some cash and I figured the extra mem in the 2nd video card wont make as much of a difference as that in the first.

Thanks!

If you sli a 640 and a 320 I think the 640 only uses 320 out of 640. So basically you waste 320 megs of vram.

Currently at 3.30 @ 1.41875V.
12 hr orthos stable with a load temp of 61.

He's correct, you'll end up with basically two 320's SLI'd, you might as well spend the little extra and get another 640mb version
