up your NB to 1.56v That is what i had to do

THEN - the wife turns it on this morning and it blue screens in windows. I can test the snot out of it at the end of the day and it's always perfect at 3.0, but first thing in the AM when wifey turns it on it blue screens. *** - ins't heat supposed to be bad not good lol. It starts perfectly every day at 2.9, but seems to fail every morning at 3.0 - once up and running I can go back to 3.0 all day without any trouble. I'm wondering if maybe MS defender or AVG scan is running first thing in the AM causing truble, or if it really is trouble when cold????

Anyone seen behavior like that before, or have any suggestions?

Summary is 1.35 manually set on core, 1.39 NB, unlinked, 1500 (or 1450 when I back it to 2.9) fsb, memory at 800. Timings of 4-4-4-12-2T at 2.1.

Any posibility that I should back off on the timings when running at 3.0? Memory is unlinked at 800 so I don't think it would matter but I'm not sure what else to go after?

First the P5n-e does support 45nm Dual cores not quads. Second sorry for repeating what you said about the NB @ 1.56v (i hadnt gotten down to this reply). I had the same problem with 1000mhz and a high over clock. The only thing i can figure is there is too much vdroop on the ram. The only reason i came to this conclusion is the new mobos from asus have two phase voltage regulation on the ram. I did get 1000mhz on the ram and 3.0 at 1.4ish but it required 1.748v on the NB, which i am not going to do

Try turning up your NB to 1.56V, then try 2.25V on your RAM if increasing NB volts does not help (if you're comfortable that your RAM can handle it...Micron D9GMH's can) Last, I'd back off the timings a little....4-4-4-12 should be no sweat for any DDR2/800 rated ram @2.0-2.2V.

I had real problems with 1066MHz RAM and any FSB other than 1066MHz (1:1 was ok, but OC the CPU, and my RAM is only stable @ 1000MHz.) Could be something similar....1333 to 1066 MHz was an awkward divider....maybe 1500 to 800 is the same deal. Can your CPU run @ 1600MHz on a lower divider? Try that too if you can.

Edit:

your Corsairs should be good for 2.25V...but I note that your PSU is 450W. Could be that the PSU is slightly undersized- I had problems with my PSU when I upgraded to the p5NE...465W on my enermax just was not enough.

Edit 2:

If your RAM is in the yellow slots put them in the black ones. My ballistix would only run 800MHz 5-7-7-31 2T @2.25v in the yellow, and run 1000MHz 4-3-3-8 2T @2.25 in the black ones. Stock rating for my RAM is 1000MHz 5-5-5-15 2T @ 2.2V

Helo everyone,

I have the following qeustion;

i recently received a ' Creative X-Fi Xtreme Gamer ' retail version.
Now my qeustion is if this is compatible with this motherboard under vista 64 bit?
I've searched and searched but i cant seem to find a conclusive answer to my qeustion. Any help consisting of information about this will be most appreciated.
Maybe if someone can find the time a quick step to step guide as the best way to install this new soundcard.

Many thanks,

Big Ron

Good to know. Still, I think it's a gamble at best. Many of the P35/x38 motherboards with much better voltage regulation actually are pushing the voltage limits of the 45nm. In some cases some minimum voltage settings on the board are at or above the Intel maximum voltage for teh 45nm parts. (not just Vcore, but other voltage settings we don't see on the P5Ne like VTT)

No prob...Personally I think it's the NB MCH strap settings. 650i was not designed with DDR2/1066+ in mind....remember DDR2/800 was hella expensive when the 650i came out.

Oh yea...I feel ya on the Zalman....even on 100+F days my CPU stays under 60C (100F~40C ambient)

Ive done the dirty. Ive gone and got myself a P5K, so im saying farwell to my old board.

So I just picked up the P5N-E and want to get some new heatsinks/fans for it so I can start oc'ing. So who has what that fits on the board with no mods necessary, CPU heatsink/fan, NB heatsink/fan, and SB heatsink (fit with an EVGA 8800GT).

Look at the first page to see what works on this board and what fits.

I got mine oced to 3.2Ghz with a 1:1 divider and had the vcore up to 1.4v but it seems to lock up every now and then. What voltages are most of you seeing you need to run to achieve a stable 3.2-3.4 oc? Also has anyone ran the beta Bios yet?


Also what chipset drivers are you all running?

x-fi x gamer works fine for me with vista 64bit, just get the right driver from creative (both parts)

the 45nm cpus are less demanding on the power regs than the 65nm one across the board and this is the reason i was looking at one with this mobo lacking in this department.

ram, yellow slots are hit and miss once you get above dd800 and the black slots are the same once you get above dr1000, they will both work but gave me random bsod.

i had more luck staying on a 1:1 divider untill i found the cpu settings i wanted and then tried to get the best out of my ram as this board can boot with daft dividers but some hinder performance quite a bit by being very inefficent. i run 24/7 on 400fsb x 8 with my ram on ddr1000 5-4-4-12-2t - 22.

care to colaberate?
i'd be verry happy if u would be able to direct me to the right drivers just to make sure i have the correct 1's. Cause u might never know and i like to listen to music ;p
