Biostar TA790GXE 128M -- CPUs supported?

post #1 of 30
Thread Starter 
So, a little while ago, I bought this motherboard. Specs are here:

http://www.biostar-usa.com/app/en-us...n.php?S_ID=408

While installing, I added a new CPU, since the main reason for the board was to upgrade from an old AM2 Dual-Core to an AM3 Quad-Core. So, I bought a really nice one, an AMD Phenom II 965. The exact model here:

http://www.newegg.com/Product/Produc...82E16819103727

Now, I had some strange problems, such as my computer randomly shutting down while doing some CPU-intensive work (such as large installs and the like). Eventually, I got to the point where I put my old Dual-Core processor in, and now the computer works fine.

After coming on here, somebody suggested checking to see if the board would support the CPU I tried to put in it. Looking at the compatibility list on Biostar's site, I see that it will support Phenom II 965 processors. However, the model number on mine is slightly different (HDZ965FBGMBOX, as opposed to the two recommended models, HDZ965FBK4DGM and HDZ965FBK4DGI). Does it seem like they're different enough models that my board won't support the CPU?

I just really don't want to have to shell out another $150 for a new CPU when the one I have is perfectly good. My BIOS is updated with the newest version, my CPU fan is a damn good one, and I can't think of anything else that I could check. Can anybody help?

The issue isnt the motherboard obviously the issue since your other processor.

what exactly happens when it shuts down?

do you get any warnings or anything?

also are you overclocked?

the issue is the cpu, so do you have a warranty or anything?

the issue ISNT your model # or cpu fan (at least i dont think...). What are your temperatures when you install things? you shouldnt go over 60c or so...

Is the CPU vcore option in the BIOS set to auto? Did you clear the CMOS when you installed the 965? If not the BIOS could still be set to the old voltage value for the dual-core and not the 965.

It just shuts down, as if I had hit the "shutdown" button. No warning or anything. I didn't overclock my CPU, and I lost all the warranty info for it already.

I didn't check the vcore option, because I have no idea what the heck that is. And my quad-core CPU was the first CPU I installed on my motherboard, so it would have never had settings from my dual-core. I didn't swap the dual-core in until I had reason to believe my quad-core was the issue.

The vcore option is the CPU voltage specified in the BIOS. With the 965 installed I would suggest going into the BIOS and setting the CPU voltage to manual rather than auto. At that point, set the actual CPU voltage value to 1.4 or 1.425 and see if there are stability issues. My 955 at stock volts is set to 1.4 so that should be a good starting point.

i have the same board make sure your bios is up to date i have the x6 core installed, so your bios maybe out date there for you can only do AM3

Have you checked your temps? CPU intense work = high temps = recipe for a crash. I would look there first. I mean if you can get in to Windows I wouldn't think its a compatibility issue...

I wouldn't want to think it's temps. I have a really good fan. I work my dual-core like crazy with the same CPU fan, and I never have any problems. I'm thinking it may be a voltage problem. Since Darklink mentioned it, I do believe I had my vcore set for auto. I'll try the Manual at 1.4 and see if that works out when I get home from work today.

Well have you at least looked at the temps? It doesn't take much time and you can then definitively rule them out. A good fan doesn't mean much if it comes loose or something...
