The Q6600 has a max multiplicator of 9. Change the fsb frequency for overclocking.

I have a Q6700 OC'd to 3.2 GHz (via 1280fsb). I am using bios 1203 on the P5n32-e. The OC seems stable under prime, etc.

The issue started while I had some corsair memory (4 1 GB sticks). The computer would power up but not hit the post screen. The monitor would not get a signal. After changing some of the memory timings, the problem seemed to have vanished for some months. I had been running the memory at a 3:2 ratio which put them at around 850mhz. This and whatever timing changes (I set to the rated timings and voltage) seemed to resolve this problem. However, I have installed new memory modules with different timings. Two 2gb OCZ Reaper sticks (corsair has been removed) and the problem is back. I have set the timings to the rated spec for these 4-4-4-15, at 800mhz (unlinked, I also tried linked at 3:2 since that worked on the Corsairs but to no avail) and the rated voltage of 2.1v. I also tried at one bump up and one bump down from 2.1v. I also note, that after I reset and the post screen does appear (after one of the non-boot incidents) it shows the memory timing is now 5-5-5-18 - but when you enter setup it shows the 4-4-4-15 I set in bios. Is this a timing/mhz setting issue with the memory? Clearly something is getting reset after one of these boot failures due to it showing a different timing setting after it happens. Any suggestions would be greatly appreciated!

I have the same issue since i oced to 3.2 ghz. The machine power up but no post. I use 4x2gb corsair sticks. But the problem isn't resolved with changing voltages and timings.

OK - have done a bit more with my mobo/quad since way back when - haven't got any more fsb but have been able to isolate some things and drop voltages that weren't required.

Here is a screenshot of my current 3015 volts etc.

Things to note - CPU voltage is NOT why this board wont post with quads - it's ONLY limitations of the FSB - I have mine set to 1.26 ish. Came to the realisation when I could do 2.7ghz @ 1.1volts.

Things you need - decent north/southbridge cooling and lotsa patience.

Just a note for all - after I flashed to the 1503 bios I was able to hit 3.8ghz on my Q6600 - rattled off a 18k+ 3dmark but my cooling aint that great :S.

the 1503 bios has made a huge difference - I ran prime for 3 hours @ 3.4ghz last night (425fsbx8) and have booted at 4ghz but I didn't like the temps cos my cooler is average

Makav3li · 08-18-08

Is this repeatable by anyone else? Is the 1503 bios really the fix for quads?

Chickenman · 08-18-08

I hope so - bear in mind that there are massive holes in the fsb and my combination has got me these results - everyone is going to be different.

As long as you got a decent-ish northbridge AND southbridge (mcp) cooler (I use the evercool serpent which was nice and cheap on northbridge and have hacked up a traditional northbridge cooler to fit on with my 280 gtx) I would skip all the middle buggy frequencies and go straight to 1700 in bios with a x7 multi.

My bios volts settings are:
HT:1.25
NB:1.55
SB:1.55
CPUVTT: 1.55 (this used to always have to be low to get 3ghz

)

and my G0 will do 3ghz on 1.25-ish volts (as set in bios).

Will post some pics.

Guys, my motherboard P5N32-E SLI PLUS is ****ing with me very hard. I set up the Q6600 at 3.0ghz and manually set the voltage, but everytime when i restart and my windows load, i see the bios is switcing to automatically voltage - 1.360V. Restart again, in bios is the manually speed, but on top of that under Windows the speed is automatically again.

Why is that?

Chickenman · 08-18-08

I had a similar issue with the fsb always going back to auto with the 14XX bios before this one - grab a usb thumbdrive and flash to the 1503 bios.

burtethead · 08-19-08

i have that problem with the fsb resetting, and i have 1503. i dont understand it! in 1404 it resets the fsb every time you save and exit, and i thought 1503 would be the fix, but this is not the case. if anyone knows how to fix this auto reset fsb problem please let me know!!
