Where are the 4300 guys when you need em?

uh yeah it works, i really didnt think i needed to say anything considering its in my sig.

3.285ghz @ 1.48v baby and oh yeah last i checked the 4300 was 125bux at the egg

Keep in mind E4x00's tend to get lower OC's than the E6x00's...just make sure you have the FSB for 'em.

Ok...I've been trying to flash my BIOS, but am having some problems.
I have been trying to use the ASUS EZ Flash2 in BIOS to flash from 0401 to the 0602 file, but it won't flash and says "The downgraded ROM is not suitable for the system". I have even tried flashing all of the other BIOS files starting with 0202, 0307, 0505, and of course 0602.

Am I missing something?

[Ravin]

Ok....Nevermind. I used the ASUS update utility for windows and flashed from there. So very odd. I've never flashed under a windows environment, always used a DOS boot to flash.

NE Way.. it seemed to work. Stress testing now.

Ravin, EZFlash won't let you downgrade unless you clear CMOS first.
The reason the Windows utility worked it because there is a "BIOS DOWNGRADABLE" Option in the, er, Options section.

Doesn't make sense, right, because it thinks you are downgrading.
It has something to do with the options not being @ stock.
I have had NO issues with the windows utility (asus update) and I acutally prefer it. I know people hate windows based BIOS tools, but I would much rather flash it over using some overclocking utility in windows...

[Ravin]

Actually clearing CMOS was step #1 in trouble shooting...

Using 0602 bios xp sp2 no problems so far. Only thing are long bios post and no multiplier change.

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.

Hi and welcome.

There's an excellent guide to this board here

This board is really picky when it comes to ram timings. First thing to do is set the memory to stock settings and play with the CPU and see if you can get too 3.2.

One thing to try is to set the Multiplier to X8 and try 1600 for the cpu and 800 in the ram. This will give you the 1:1 timing you want and keep the memory speed at stock settings.
