ASUS P5W DH - Problems + Fixes Thread

[sesdave]

sesdave, of course it's not guaranteed, that's what I was trying to say all along. Weldzilla comes in and flaunts his overclocks as if it's a foregone conclusion (no offense, that's what it looks like to me ). You got to work to get it, you know I did lots to hit 400fsb - I installed watercooling, I did NB/SB cooling mod, w/o which the most I could do 367fsb.

Now, while my chip doesn't take much voltage, it does pump loads of heat - it's a B-series chip, after all I do have somewhat puny single heatercore with 2fans in push/pull config, and still the cpu heats up to 52-54 load @ 3.6ghz with room temp around 20-22C.

Well, "breaking" was a feeling I got when the comp started to reboot and freeze on me after that experimental run at 3825mhz. I did a 5 hours + run of orthos and at that point I started taking screenshots, manipulating them in windows paint, when computer crashed. Before that, I had no trouble loading windows at 425fsb (would not load at 430 and wouldn't boot at 435) with vcore 1.525, mch 1.75, mem 2.05. Now, with vcore 1.6, mch 1.85 and mem 2.2 it won't load windows @ 425fsb (still boots). Also, the previously rock-solid overclock at 400fsb won't stick, I had to change mch to 1.75 to make it stable again - with old setting of mch 1.65 it freezes or reboots. Vcore still 1.4, works fine.

I'm using 1602 bios and frankly, don't want to experiment with changing it. One reason is that I don't have a floppy (had to make unattended install with integrated raid drivers even) and another - what if the newer bios turns out worse for me and I can't go back?... if there was an easy way to switch between them... Any suggestions? If I really need it I guess I could snatch an external floppy...

My chips are definitely D9GMH, it's OCZ 8500, I even checked them physically, there's a bump in the middle I'm able to do 2:3 ratio below 400fsb but once with 400, it won't do anything above 1:1. Dunno why... I'll read that thread, see if something comes up.

Flashing back to an older BIOS I can help with as I have just tried 2004 and gone back to 1707. Download AFUDOS 2.11. Get the BIOS version you want and rename it to P5WDH.ROM. Create Boot Floppy or USB Flash boot - create Boot flash with either HP one posted or this http://www.weethet.nl/english/hardwa...musbstick.php#. Copy AFUSOS and BIOS to floppy or USB Flash. If you are using Flash USB configure BIOS to change the boot sequence so that the USB flash drive is boot before a hard drive, and also disable "Legacy Diskette A" on the BIOS Main pageBoot . Insert drive/floppy - Boot to DOS and run afudos /ip5wdh.rom
I have just remembered that I forgot to to disable all CPU configuration settings especially virtulisation when I flashed the BIOS to 2004 which might explain my spurios BSOD with that version and why I am getting them when I flashed back. I might give it another try as others are giving it good posts - might be worh checking you CPU settings. You wheted my appetite as I am getting RAM with more potential so I have been looking into the dividers - more info on 4:5 2:3 dividers from EVA2000 http://www.xtremesystems.org/forums/...7&postcount=33 points to memory with trd=6 being the culprit. He also refers t MB/NB temps - I stuck a 40mm fan on my NB which I found helped a lot. Here some more which all poiunts to TRD=6 as the problem .http://www.xtremesystems.org/forums/.../t-115729.html
