Hi guys...

Well I've been a bit busy for a while had a few personal things to take care of...

The mobo arrived as promised by Scan, and I even got it all installed into the case the same day. But didn't have time to try to install the OS until today.

Well I fianlly got the OS installed this afternoon.

I've been running into a couple of little oddities with this board compared to the M3A32-MVP.

I've flashed to the latest BIOS 0602, and have installed Vista and all updates, etc...

My temps are great, I'm just testing high voltage temps at the moment and have set VCore to 1.475v and CPU @ 3.2Ghz,

Idle is showing 36C on the CPU (IHS) with Cores showing 37C (C'n'Q disabled of course)
Load is 44C CPU (IHS) and 46C on the Cores.

The oddities I've been having are that whenever I try to amke any changes to voltages in the BIOS for CPU-NB Voltage, NB Voltage, HT Voltage, CPU VDDA etc, then the system fails to POST needing a CLR CMOS via the jumper, which is a real pain as I have to remove one of the 4850's each time to get at the jumper cap, if I keep doing this I'm usre I'll end up wearing off the gold on the X-Fire connector tabs, with all the putting on and taking off of the Crossfire Bridges...

Anyway, the other thing I notic4ed is that whenever I do a BIOS change or whenever there is a failed POST the fans on the 4850's jump to full speed and stay there, but when I usually POST OK the fans will jump to full speed upon switching on but then after a moment (like 1 sec or 2) the fans will go to normal speed, and the POST will continue, which is leading me to think there's something flakey about the Power arrangements in the BIOS for the POST procedure.

Anyway, I'm in the process of trying to figure it out, by gradually making cahnges one by one as a proess of elimination to try and rule out the cause of this littel problem.....

So far I've ruled out the following:

CPU Voltage changes - I've changed this incrementally up to 1.475v POST succeeds for each increment
DDR Voltage - This is set at 2.1v for my G.Skill RAM to run at DDR2-1066, this is fine as well.
CPU Multi - 12.5 up to 16 all OK
NB Multi - 10, 11, 12 all OK with NB Voltage at auto.

I'm pretty sure it may have something to do with either the HT voltage, or the CPU VDDA Voltage, settings that is causing it to fail to POST.

I currently am at

CPU @ 3.2Ghz and 1.475V
NB @ 2.4Ghz and (Stock Volts)
HT@ 2.0Ghz (Stock Volts)
RAM @ DDR2-1066 (2.1v)
ACC @ Auto

Pretty much everything else is on Auto settings at the moment, CPU TWeak, Auto Express, etc..etc.

I'm kind of hoping to get this little glitch ironed out soon, so that I can see what's what....

If anyone else has any idea what could be causing it or knows for sure that a particular setting being changed causes a POST failure let me know and I'll try it out to see, in the meantime, I'm oging to carry on with my process of eliminatin technique, one change at a time in the BIOS to see if I can narrow it down to a particular setting.....

It might even just be with this BIOS, I'm not sure, the first thing I did was to flash the latest BIOS so obviously havn't tried any the earlier BIOS'.

OK well hopefully back soon with an update...
