>_>;

*installing Vista, XP, and Ubuntu again*
*won't be trying*

[JCushing]

oh yeah i love installing ubuntu, dual boot with a sata drive for windows ide for ubuntu using a graphics card that isnt supported in the least with linux. although my upgrade to fiesty went without a hitch i think im gonna stick with 401.... my OC with my 4300 actually seems to be above par so dont mess with it if its not broke.

speaking of broke the fan on my TT NB cooler (cl-c0034) is making a nice buzzing noise and the RPM sensor doesnt apear to be working. i actually had to tap the damn thing to get it spinning up to full speed.

hello, I'm Sanch3z and I'm having a bit of difficulty getting my Asus P5N-E SLI based system stable when overclocking. I have a Core 2 Duo e6420 and Corsair TWIN2X2048-6400C4 2GB Kit DDR2-800 memory. I can do slight overclocks up to 2.6ghz and the system remains stable but I want at least 3.2ghz +. Whenever I go over 2.6ghz and run test software, orthos, memtest, sandra, after a couple of minutes the system freezes. I have tested all components @ stock speeds to rule out any hardware failures, passed memtest and 10+ hours orthos at stock speeds. Temps are not an issue either, under 45c @ max load

maybe its just a wrong setting in bios, 0401, I am using. here is what I'm using (I partially followed a guide from ASUS forums):
* Windows Vista Ultimate, no aero
*memory in yellow slots, black would'nt even post

*memory timings: 4.4.4.12 command rate 2T TRc 22 clocks @ 2.1V

*Vcore 1.35 have also tried 1.45

*disable USB legacy support

* AI tuning [manual]
FSB to Memory [unlinked] which makes FSB Memory Ratio greyed out
FSB upwards of 1600
mem 800mhz
NB core voltage [auto] have tried manually setting to 1.39

I am leaving FSB to memory ratio unlinked but CPU-Z reports FSBRAM at 15:16.

any help would be kick ass, TIA.

Sounds to me like the same issue I had...
Try auto voltage on vdimm.
I know, sounds odd, but it worked for me.

Otherwise, I would say it's the PSU...
I have looked at about 5 reviews on that PSU and the numbers seem to be great, and it is even recommended highly. But the only problem I see there is the fact that all those reviews were written pre-G80's.

I am wondering if the 8800 is drawing too much off that PSU. The numbers on it are impressive tho... If the RAM trick doesn't work, try the PSU.
Oh, and if that doesn't work - is your GPU overclocked? If so, try reverting to stock speeds and see if that work.

I think out of those 3 options it is most likely the RAM trick. If not, maybe OC'd GPU, and lastly PSU.

Try em out, let us know.

PS Nice lookin rig. I don't like alienware, it looks cheezy, but that is pretty sleek.

Well I won't be updating my buddies Bios then. He likes having the changeable multi for OCing!

[dpawl31]

That's so irritating, huh?
Guess I have no worries with my locked 14 multi lol.

[JCushing]

well new egg is awsome, they just refunded me the money for the TT NB cooler i have http://www.thermaltake.com/product/C...4/cl-c0034.asp

i now have a thermalrigth HR-05 non sli on the way http://www.newegg.com/Product/Produc...82E16835109128 with a 60x15mm fan and a replacement 40x10 fan for my old one.

im pretty happy with my zalman passive sink on the SB so i dont think ill be re-using the thermaltake once i get the fan in if anyone wants it?

lol... yea- Released 4/27. So far I have not noticed any difference between 0401 and 0602. All the settings are the same and stability does not seem to be an issue. IDK about the multiplier lock- I'm etched on die for 14x anyway.

Hey- Just browsing thru the intel CPU folder and took note that the socket T Xeons may run on desktop chipsets? Anyone here hear of running a Xeon on the 650i chipset, more specifically on our board?
