ASUS P5N-E SLI 650i Thread

[xaks]

thanks for pointing me at Tribeca's guide, that's some awesome info.

oh, and just an FYI, I'm running the 0608 BIOS on this thing...i just bought the board a couple weeks ago and that's what was on it. is there anything really that exciting about the 08 version that i 'gotta have'?

[r0b126]

ok, I clearly need to call someone and do this over the phone with someone with experience OCing the E6750...anyone feel like PMing me their number?

I went into jumper free config on the 0801 bios and changed the AI tuning from auto to manual.

in the fsb and mem config option, I changed fsb memory clock mode from auto to linked and then changed the fsb mem ratio to 1:1....next, I manually changed the FSB (QDR) mhz to 1600.

this all sound right so far? if I change it to 1600, that technically means it should be changing the base freq from 333 to 400. The way I am seeing this is that the 333 x 4 (for qdr) = 1333 for my fsb and then I multiply by 2 for the DDR and I get my 2.66GHz cpu clock speed. now if I change it to 1600.... this, I Am assuming means it changes teh base freq to 400 automatically which should result in a 3.2GHz cpu clock speed and 1600mhz fsb

when I esc out of this option and go to the cpu config page, it still shows the cpu clock to be at 2.66ghz

any thoughts or opinions? I don't want to do this wrong and fry the cpu...thanks.

You need to reboot to see the effects. Don't worry about frying it...I believe you would need to mess with vcore to do that, or just have ridiculously high temps.

[r0b126]

rebooted, in cpu config, it still says cpu speed = 2.66ghz

[Gauvenator]

It's probably displaying the stock frequency. You'll see it with cpu-z in windows.

updated the system specs i think ... try that out!

as to the cooling: yea, I know I have to address the cooling situation right quick....that's the first thing on my list. I don't want to push it much harder without some bolt-on heat sinks over the n/s bridges and better CPU unit. But it is a good first step, methinks

I love my WC. I raided an old dead Asus boards NB for my SB. Get an Thermalright HR-05 Sli and get either the Tuniq Tower 120 or the Thermalright 120 extreme.

ok...just viewing the bios screen its saying my temp so far is at 54c after the change of fsb...gonna check windows and then check back here


edit: whenever I make a change in the bios and exit, it never boots up automatically... I have to exit, then power off and back on... this time when that happened, it gave me a warning for boot failure and asked me to undo changes in setup.


I hit f1 to continue anyway and it loaded windows just fine


in windows sys properties, it still lists my processor as x86 family 6 model 15 stepping 11 genuineintel ~2666 mhz

I believe that continues with stock settings. I would suggest gradually raising fsb in 20mhz increments instead of leaping to 1600. If you aren't able to boot at a certain point, raise the vcore a notch.

[r0b126]

ok, but even if I make a 20mhz adjustment to fsb, I should be able to reboot and see an immediate difference in the overall cpu speed, right?


also, if its not at exactly 1600mhz fsb, how do I get a 1:1 with the 800mhz dimms I am using?

[Gauvenator]

you can work your way up to 1600, but you should see a slight increas
