My RAM is a POS. Error city on mem test and I'm pretty sure it is the reason I can't get a higher stable OC.
It's rated at 1066 yet whenever it comes close to this it becomes unstable. I think 900mhz is about its limit...
Last night I spent aaaaages playing with voltages, timings and dividers in the futile persuit of a higher stable oc. I can boot up at 3.6/3.7 but mem test, 32m superpi or dual prime always fail.
I had my mch at 2.0v, cpu core at 1.55v, ram divider at 1:1, stock 5-5-5-15 latency, ram 2.3v, 400fsb*9... Grrrr! Idle temps at these settings were high 30's (37-39 degC) load high 50's. These volts are as high as I think I should go.
If I have a 4:5 ratio on the ram and put a fsb in to run the ram at approx rated speed, say 1050, then the thing wont mem test or prime etc. If I back down so the ram is around 890 then its ok. Thats why I went to the 1:1 divider, to give headroom on the ram/fsb setting... This got me my 3.6 but, again it wouldn't prime etc.
Then I fettled with settings focusing on ram, it just errors if I go over 367*9 regardless of dividers or voltages.
Is this mobo a bit turd? Or is it the ram? Or me? Am I a big overclocking turd that doesnt know what he is doing?
