ASUS P5W DH - Problems + Fixes Thread

[Khalmyr]

I've been reading here for a while and just now it bothered me so much i decided to create an account...

Here is my config:

Asus P5W-DH Rev 1.04 Bios 1804. Removed covers for North and Southbridge. AS5.
C2D E6600 @ 3.402mhz (378x9) - 1.4375v. Zalman 7000B CU - AS5
Corsair XMS2 DDR800 @ 756 4-4-4-12 1.8v
Asus Radeon X1950Pro


I feel that my vcore is imuch higher than everyone else's at the same clock. If i put it down even just a bit it can't get stable in Orthos... With 1.435 i've gotten 24h Orthos stable. My E6600 is a L632B which are supposed to be pretty good for low voltage OC.

All other voltages not mentioned are in auto but I doubt this is related to vmch because most 1.04G can get 400fsb easily and I've tried raising my vmch and it didn't help.

My voltages after vdroop are 1.416 ~ 1.392 for idle and load.

I just want to lower this vcore because my cooler is pretty old and it really limits my OC. Changing coolers now is out of question as I just went bankrupt a few weeks ago :P

Any help will be appreciated

A quick update here...

I've tried playing a bit and I could get stable at 425 x 8 = 3.4Ghz @ 1.4v

A huge improvement since I kept the clock and even raised the fsb.

vcore = 1.4000v
vmch = 1.75v

Something weird though. My sticks can do 800mhz 4-4-4-12 @ 1.9v. I've ran memtest and orthos when I had a better cooler and ran the CPU @ 400 x 9 daily.

Right now I have to run my memory at 4:3 @ 318mhz

If i try 1:1 which would mean 425mhz it won't get Orthos stable even after i've crancked the vmem up to 2.2v and changed the timmings to 5-5-5-15.

Pretty weird..

Any suggestions?

As most of you know by now, ASUS have locked multipliers on X6800/QX6700 (BIOS 1602 - 2001) and as we are approaching the launch of R600 and it's bench time again, I need to "downgrade" to 1503, 1506 or 1601 in order to get my system in bench modus again.

However, I am currently running BIOS 2001 and this does not let me revert back to any of the former mentioned. And for some reason I am unable to create a start-up disk and therefore cannot use the Afudos 2.17/2.11... The box where I am supposed to tick off the Start-up version is greyed out and I am just to stupid to figure out how to solve this.

Will BIOS 2004 let me "downgrade" or do I have to get my supplier to create a start-up disk (USB penn) for me with Afudos in order to revert? Or should I just buy a new MOBO and prey that the BIOS accompaning the board is downgradable or the right one... Sorry to bother you guys but this is killing me...

Just did a quick test using BIOS EZFlash 2:
- could NOT revert back to 1707 from 2004
- message: "... motherboard is older than firmware..."
- with 2001 or 2004 installed, reverting back to 1901, 2001, 2004 appears to work with BIOS EZFlash 2
- appears AFUDOS 2.11/2.17 is the only option for reverting back to BIOS older than 1901

Use this program from HP to format your USB device to make it bootable. Once it's set, you can copy over your bios files and the afudos 2.11 program to it and boot.

I've used this program to make my usbkey bootable for when I need to reflash my xbox 360. Works great!
