Hello everyone,I have bought a P5K-E wifi to replace the P5N32E for my Q6600. P5N32E is not very fit with Q6600 for OC. The newer its BIOS, the worse the performance. Now, with the P5K-E, I can OC my Q6600 to stable 3.5G, maximum 3.6G. Overall, I am very satisfy already with this performance.My question is, I use Scythe Ninja plus heatsink and fan. The idle temp keeps around 50-60. Only sightly lower than using stock HSF. When operating FSX in window mode, temp goes up to 78 degree. Is this normal? Or there is problem for my HSF installation which case the high temp?Moreover, I want to know what may be the cause of the following OC crash symptom.1. I try higher FSB and OC it to 3.65G. It can start and enter windows. However, it goes to Blue screen very shortly after started Windows. I tried given more or less voltage which doesnt help. (What does it mean? memory problem? cpu cannot stand for it? MB cannot stand for it?)2. Try OC it to 3.7Ghz, it goes to blue screen during the Window starting loading bar and reboot.3. Try OC it to 3.8Ghz, it goes to a black and white page during the Window starting loading bar, and said I miss a file when loading window. I do not really mean to OC it even higher than 3.6Ghz. I do want to learn what does this symptom really telling me. Thank you very much!Alkit

That's my rig too. What are you looking at for temps. 78C Tj is fine. But try Prime 95. I doubt that cooler will handle it . . . but you are not flying Prime. If it's stable for the sim, that's fine.I'm assuming you have DDR2-800 ram. RAM MAX: As an experiment, drop your CPU multi to 6. Bring your FSB down to 266, them adjust the FSB to a near value that provides DRAM speed dropdown menu choice (in the bios) of around 825. Bump your ram volts to 2.3v. Boot and Prime. OK? Go some more FSB. Repeat 'til it won't go no more. That's your ram's limit. Make a note. FSB MAXNow, leave the CPU multi at 6, set the FSB to 400 and the ram back to 800. Bring the FSB up. If it breaks before the ram hits the noted speed, you have hit the FSB limit. Make a note. (You might not be able to hit a FSB limit with DDR800 ram. At the slowest ram setting (1:1), the ram will probably catch fire long before the FSB breaks a sweat . . . but give it a try.) CPU MAXNow, go back to the default CPU multi and a 400mhz FSB. As long as your ram and the FSB stays below the noted speed(s), you are hitting tour CPU's limit.And now you know who's doin' what to who (whom?).

Hello Sam,Yes, I am using 2x1GB DDR2-800 ram (Corsair).Thank you for the guidence!Whenever I set my ram volt to over 1.9v in my last P5N32E, the machine will not POST. Do you think there may be an improvement with the new mb? I thought 1.9v may be the hard volts limit that my ram can take.Will do the tests soon!!Thank you!!Alkit

The corsair is the problem. It'll run at rated speed, but generally no more. Try it with 2.2v, then 2.3v. Maybe they've gotten better. I'd be interested to see. Let us know.

For the ram, I can set them to 4-4-4-12 by 1.9v.Cannot feel any better however.Will try to increase the voltage and see if it still works.Today I also try lower the CPU voltage to the lowest possible in BIOS 1.1v. I was expecting the core temp to decrease. However, it not much different from setting AUTO in BIOS Vcore (about 1.2v something). May be only 1-2 degree lower.Alkit
