Hello, my name is Octavian and i have an issue with an old G41 motherboard, Gigabyte G41M-ES2L (rev.1.0, BIOS latest version, F9). The CPU is E6750.
Until yesterday i used two 2GB Kingston memory modules, 1x KVR667D2N5/2G and 1x KVR800D2N6/2G, and the memory clock was obviously running at 667, since I had one lower than 800. So i thought is better to have both at 800 to rise up the clock at same speed, and I replaced the 667 one with KVR800D2N5/2G. But surpise, the memory still runs at 667 MHz, i saw that in BOIS and also with AIDA64.
I don't understand why, since the board is supposing to work with 800 MHz memory modules.
If I try the memory modules separately, it shows they run at 800 MHz, but not toghether.
The FSB is shown at 333 MHz and the CPU multiplier is 8x, everything as default or 'auto'.
The board runs automatically in dual channel mode and i have no option to disable it.
If I modify the FSB in BIOS from 333 to 400 MHz (just changing, not saving the settings), memory will go at 800.
Also in BIOS it has an memory option that I tried to set from 'auto' to 2.40G, Memory was at 800 MHz but system was freezing after 30 minutes, so i changed it back on 'auto'.
I checked your articles about this board but I found nothing releated with such problem. of course may be a compatibility problem or something else, I'm not sure that is the fault of the motherboard.
Thank you very muich for your time, best regards,
Octavian
