ASUS P5N-E SLI 650i Thread

[ru7hl355]

anyone had any success reaching 3ghz on a b3 quad on this board? i am thinking of trying another board but if it can be done i will give it another chance.

The kicker for me was when trying to find my ideal FSB, & it wouldn't boot, even with the 'features' it has to recover from this, I had to have the case open, move the jumper, wait & move it back....my fingers nails canne take it captain as they put it in a stupid bloody place!!! The NB not being seated properly with thermal paste ... the Bios is crappy....

There are thing I do like with this board & for non Quaddies it sounds great .. but for me it was just too frustrating.... RIP P5N-E Sli... & good riddience.

A wee update ... I've had my Q6600 running in my GA P35C-DS3R at 3.2Ghz on air & it's perfect at (8x400). Temps were ok. I added my water cooling in yesterday & I can get into Windows at 3.6Ghz, it does crash after about 10mins or so. 3.4Ghz runs a 3DMark06, but freezes in COD4. With some tweaking I'm sure I'll get it working at 3.4Ghz stable. My idle temps at 3.2Ghz are around 42c, at load under 60c.

It's about time. I went and upgraded to the P5N-E SLI and you leave...so I downgraded to a socket A. :P

Just kidding.

Just when he comes back, im thinking of going to either a P35 or X38

Yes, it does. The offset (as Tribeca finally got across to me) is merely a secondary/auxilary way to supply your chip with voltage. If you have the offset on you add that to your Vcore to get the total voltage. The offset uses different mosfets than the ones for the Vcore setting, thus puts less on the Vcore mosfets. Its almost a trick (assuming that's not the offset's purpose entirely), a very convenient one though.

Where the hell did you go man.....
You missed the upgrade from D820 to Q6600. BTW....fried my 820 and got a new one from intel RMA.....care to race CPUs again?

Hello , i'm a new member.I also have the P5n-E SLI. It works great, I used the ai overclock option only cause i couldn't find all the values i thought i had to set.My computer is set at 10%OC.any suggestions what order and values to set to get higher OC?

Hello Markt,

First things first, this will help you out tremendously: P5N-E Overclocking Guide. That will tell you how to tweak voltages, speeds, and other settings. Of course we'll help you out here too, but that's just to get you started.

I also used the "ai overclock" the first time I got my PC just to get a "feel" of what it could and couldn't do, then after that I turned it off and made my own modifications. First make some simple obsevations. Turn off the "ai overclock" and record or remember the stock speed settings, the current temps, and voltages then turn the "ai overclock" on again and notice the differences. You can do all this in BIOS. After you tweak it, you can go to the CPU settings section and see the current multiplier (might be fixed) and the speed in MHz. Also there is a hardware monitor in the BIOS which can monitor your mobo & CPU temps. It's useful to look at those.

The P5N-E should have come with some software which will be useful when overclocking called PC Probe II. It's not top of the line (and you'll need to get other applications eventually like SpeedFan [Highly recommended], CPU-Z [Invaluable], and for stress testing an OC: Orthos) but it does the trick. You can monitor differences in temp, Vcore voltage, fan speed, etc. For me personally, since my core is locked (I can't increase the multiplier) I OC by increasing the FSB speed (which can go astoundingly high - so not really an issue for the FSB itself). Try upping it in small 25-50Mhz increments at a time till you get comfortable. Once you get it OC'd by 100 or more MHz you might want to then consider tweaking the voltage a little (you can take very small steps in the BIOS) by turning auto off and increasing it by one or two increments up. You do this by first observing for a time the Vcore voltage values displayed in PC Probe, and then you know what it usually is set at, then just incrementally increase it till you think its stable.

There's a lot more to get into but this should do for now.

Welcome onboard,

~Josh

weird problem, managed to get my q6600 to 3ghz, but now i cant clock my memory upto 930mhz like i could before when i was @ 2.66mhz.

is this normal for this board?

vcore = 1.26878
memory=2.178
nb=1.56
100+mv

Your ratio is off. Try adjusting ram speed. You may have to go slower.
