I recently upgraded my Asrock 775 Dual VSTA (with VIA® PT880 Pro/Ultra Chipset) with modded bios 3.17a, so I would be able to put 4GB DDR2.
I purchased 2x2GB DDR2 800... I read somewhere that it will downscale to supported frequencias (motherboard says 667/533).
The system is now unstable, with BSOD and freezes randomly... BIOS options are default (RAM voltage and freq is auto, recognized 533 -not 667-)... I ran memtests and DIMMs seems to be ok, so maybe it is some BIOS option that I must change... maybe timings? voltage?
Any help will be appreciated! Thanks a lot in advance!
