F2-8500CL5D-2GBPK / Kuma 7750BE / Asus M3A78-CM Issues

Bought the following combination for my primary build….. F2-8500CL5D-2GBPK / Kuma 7750 BE / Asus M3A78-CM. With the three together no matter what I do there is no boot/start/run/whatever.

However the following will work:

1. The PC2-8500 / Brisbane 4000+ / -CM will boot and run.
2. F2-6400PHU2-2GBHK / 7750BE / -CM and not only boots but I’ve managed to overclock the 7750BE to 3.187GHz stable with the 6400 memory set to 2.1V 677-4-4-4-12-2T.
3. The PC2-8500 / Opty 1210 / Abit nf-m2 nView motherboard combination overclocks very well. The memory has allowed me to run a stable 3.1+GHz.

Also the memory has run several passes of memtest without errors.

SO does this mean that the memory and processor are not compatible??

I would check ASUS' site for their memory compatibility chart for that motherboard. If they're on that list then I would email ASUS support and see what they have to say.

Sadly Asus's compatibility info is almost a year old and not very incourgeing....they only list intel boards! :( However it will run on the -CM, just not with the 7750BE. NOt sure if I'm missing some little item in the bios or not. :oops:

Worst case scenario I'd say you might want to sell that RAM and use the kind you know works with that CPU

Oddly enough I'm using it in a system whose PC2-6400 I stole and is helping me get a stable 3.15GHz out of my Opty 1210 (1.8GHz stk). :) Only issue is that it is recognized as PC2-6400! :lol:

Meanwhile the F2-6400PHU2-2GBHK is helping me get stable 3.187GHz out of the Kuma
