Asus A8V freezing / lockups / cold-booting ** FIXED **

[William Dobiney]

Hi all !

I have finally found the BIOS settings that eliminate all of the A8V freezing / locking-up / cold-boot-failure problems my board has. Is short, my rig, and its settings are as follows:-

- A8V Rev 2.0 Dlx
- BIOS 1007
- 3200+ 939 Winchester .09
- Zalman 7000 AlCu with *no* fanmate – fan speed constant at ~ 2700rpm
- 2 x Corsair 512 DDR XL @ 2/2/2/5/11/16 @ 2.8v
- Topower 420w P/S with 26A @ +3.3v, 42A @ +5v & 18A @ +12v
- CPU @ 274 x 9.5 = 2.602mhz
- Vcore 1.575 in BIOS = 1.568 <-> 1.584 in CPUz
- Memory @ 3:2 = 200.2mhz
- HTT 600
- DDR 2.8v **
- AGP 1.6v **
- VLink 2.6v **
- Pwr Management in BIOS OFF / Disabled **
- AGP Fastwrites DISABLED **
- AGP Aperture 32mb **
- AGP/PCI 66.66 / 33.33
- Command 2T DISABLED [ 1T ]
- PCI Delay Transmission ENABLED **

BIOS 1007 with the above settings results in a system that gives me no random [ or otherwise ] freezing, no random [or otherwise ] lockups and no cold-boot-up failures – also it is fully Memtest 1.4, CPU Burn and P95 stress-tested and stable.

Temps, as measured in AsusProbe, in a cool-mild-room [ 20’C ] give me 38’C at idle and 53’C at full-maximum-artificial load – reached 53’C at the 2 hour mark and stayed there for the next several hours.

Ironically, the breakthrough for me came when, in a last ditch attempt before putting the board on eBay, I tried a final BIOS “down-grade” from 1009.XXX, including 1009 final, back to 1007 – that in itself fixed most of my problems – the BIOS settings marked with a ** did the rest.

Only took (4) !!!!!!! weeks to sort out - at one stage I thought that the [rather low] 18A on the +12v line in the P/S may have been the problem.

I have yet to try the above settings with the 1009 BIOS, but quite frankly, am in no hurry or rush to try given that 1007 is fine.

Hopefully the above may help others.

Thx,
Will

Does this bios version 7 detect dual channel memory?

Which Video card are you using in your system?

Holw cow, good job! Hopefully you have fixed things permanently.

Stories like these (I experienced many myself) are why I stopped building AMD systems for friends and family. No matter how "quality" a board was, I always had some sort of problem with VIA chipsets -- but never had any with Intel chipsets. My next system will probably be AMD, but I'll try a nvidia chipset.

Hi EDB

Does this bios version 7 detect dual channel memory?

Yes

Which Video card are you using in your system?

Basic GForceMX 64meg card - I am not a gamer

Ok Thanks William,

Your success does give me hope though. I've been experiencing the same symptoms with my own system.

I have the XFX 6600GT (sort of regret it now, considering the issues people are having with them) Video card.
I have tried various drivers for the card, updated everything else on my system and yet am still suffering.

I had tried the newest "final" bios from ASUS v1009#7 and I found it to be just as unstable. I'm currently using v1009beta6 with Forceware 65.73 and seem to be ok at the moment. Video performance suffers right now, but i'm not into heavy gaming right now.

every bios i've used (which is pretty much every version since 1007 has detected dual channel memory (check your slots being used EDB).
