I,m new here and my first question is regarding RAM configration.
I have an Asrock NF6GVSTA, 2GB DDR2 800 Kingston kit and an AMD X2 5200+. According to CPU Z my memory runs at 400mhz right now ( 200mhz ram speed ) and I can't figure out what changes should I make in BIOS to set the RAM to 800Mhz as now its running half speed.
I tried to manually set the RAS, CAS etc values as shown in CPU Z Jedec for 400Mhz but nothing changed.
I noticed that if I enable AM2Boost in BIOS the memory ideed runs at 400Mhz but I loose AMD Cool&Quiet function and others as well.
O_o that can't be right. Your memory divider is reporting CPU/5, which would be 542 DDR 1084!! For some reason it seems to be giving you the base (or Bus) speed instead. Otherewise you would have to have a memory divider of 13.5, which I assure you is not the case (only whole numbers 13 or 14 no 13.5).
If the divider is set at 13 then your memory should be running at 207, not 200 so it's wrong. I'm going to have to say it looks like you have a BIOS problem due to having an outdated BIOS. Looking the ASRock support page there was a few BIOS updates since the initial release and one of those updates was for memory issues
You gave me a link to A-LiveNF6G-VSTA wich is another mainboard, mine is AM2NG6G-VSTA, but, I just did rewrite the latest BIOS version just to make sure, nothing changed unfortunately. Still multiplier is 13.5 or 13, memory is seen in BIOS as DDR800, it is set at 400Mhz but still runs at 200, have no ideea what is going on ! This is becoming a mistery
