GA-MA770T-UD3P R1.1 BSOD in Windows 7

[jcuster06]

My System Build (Hardware)
PSU: 650 Watt Dual Rail 22 Amps per rail
MB: GA-MA770T-UD3P R1.1 BIOS (tried f10, F11c, F12)
CPU: Phenon II X4 965 3400Ghz
Memoy: 8 Gig Kingston Value RAM DD3 10600 (2 Dual Channel Kits) P/N KVR1333D3K2/4GR
Video Card: HIS ATI PCIe HD 4670
HDD: WD Green 750 Gb

(Software)
Win 7 64bit Professional
MS-Office 2007
Ulead Video Studio X4

(Issue and troubleshooting)
BSOD at random times with random logged events.  the BSODs are frequent in manner every hour to two hours.

I sprayed out the computer with canned air.  I've Updated the BIOS with Using Fail-Safe Settings. Repaced the PSU & the HDD.  I've tried WDM drivers and tried Manufacturer drivers  There has been no resolution. I've tested the RAM with the Windows Memory Diagnostic and found no errors.   tested each stick of RAM indiviually with memtest86+ and found no errors, when I test the RAM with three sticks or more I get errors.

Interesting enough if I take out 4 gig of ram, the Win 7 Installation seems to be fine after testing for about a week.  Though I would like to use of 8 gig, also I've tried to 6 gig and I can go about 1 day to a week without a BSOD.  I've tested each stck of RAM with successfull results.

I looked on the Kingston Support page and one of the articles in short says to slow down the memory bus,  I'm not sure how to do this in the MB's BIOS.

I see two areas that could be giving you problems.

Firstly the Western Digital Green drive is not good as a boot drive as it will keep trying to power down which can result in problems.

Secondly if you are filling all the slots with memory you are going to have to input the memory settings by hand, auto probably wont work. You will also need to tweak the voltage a touch for the memory to compensate for the extra load you are asking it to run. I am not sure of the exact  amount  to increase though as my field is Intel systems but I'm sure one of the AMD guys can help with that.

Try increasing either CPU-NB or RAM voltage a notch or two. Maybe even both. It's most likely the stress of using more than 2 sticks of RAM that's causing your BSODs. Myself, when I went from 2 to 3 sticks I had to raise my voltage a notch to keep them running the same settings as with 2. With all slots filled it's often that you won't be able to run your RAM ( or memory controller ) at specified voltage.

Eventually dropping RAM multiplier by one may solve the issue at the cost of RAM speed.

All of these settings have to do with bios but they're rather straightforward.

bios screen:

CPU-NB:  go into M.I.T. -> set System Voltage Control to manual -> raise CPU NB VID Control by one or two notches
RAM: go into M.I.T. -> set System Voltage Control to manual -> raise DRAM Voltage control a notch or two

Now, I'd start with upping either RAM or CPU NB voltage a notch and seeing if it fixes the problem. There's no point in increasing voltage of both and by a lot if it's not necessary. Generally if adding 0.05v to both of these settings won't stabilize your system it's probably something else.

Lastly, don't worry if your "System Voltage Optimized" message switches to red "System Voltage Not Optimized" as it's normal when going from auto to manual settings.

Thanks for filling in the details there  bytheway_r.

Thanks so much guys for your help. the BIOS suggestions seemed to make the difference I needed.  I had to incrementally up the voltage and test but I think I got a reliable computer again.  TO ALL Thanks so again!!

Very glad to hear that everything is hunky dory again!
