Vcore problem

February 6, 2010 at 09:38:55
Specs: Windows 7 32-bit, 4gb Ram
I got my athlon 620 running at 3.25GHz at 45c
under full load but its unstable cause i cant
change the cpu vcore from its default 1.28 to
anything higher. I got a program with the
motherboard which allows me to OC and
change voltages while in windows (and it
works cause it made the cpu stable and 1.3v)
but as soon as i restart the pc the voltage
drops back to default and the cpu is unstable.
In the bios it won't allow me to go higher than
1.26v but auto puts it at 1.28, what can i do to raise my cpu voltage permanently? the board is a biostar ta790gx
a3+ and bios version is 080014 of American
Megatrends.

Another thing, soon as i go above 250 fsb in
the bios everything goes trippy on the screen
with weird colors, is this because the cpu is
not getting enough voltage? (i made sure its
not my ram clocked to high as i underclocked
it then to 800Mhz as a test and my ht as well
underclocked)

The software approach is not the way to go. You need to enter the BIOS & configure the settings manually...do NOT use the Auto Overclock settings. Set the OverClock Navigator to manual. You'll need to lower the RAM speed, lock the PCI-e at 100MHz, lower the HT multi, disable Spread Spectrum, disable Cool 'n' Quiet, raise the CPU frequency, etc. To increase the CPU voltage you'll need to adjust both the Core VID & CPU Vcore.

Read your manual.

My bios that u currently got is different to the bios the manual
uses even though i still got the original bios that the mobo
always had. There is no CPU FID / VID Control anywhere in the
Bios no matter if i put it on Manual overclock / normal / automate
overclock.

You have to go to the T-Series menu, change Overclock Navigator to Manual Overclock. Open the Manual Overclock System menu, then open the CPU FID/VID Control menu...that's where you'll find Core VID. It's all in the BIOS chapter of the manual.

then i need to get the latest BIOS for the mobo since the options
i got under T-series in the bios dont match what the manual
shows, its warning sign is also different so it must be a different
bios compared to mine
