Well sorry for my poor english, and confirm that mobo isn't good for OC, i've too the M3A78-EM and the 7750+ and my max OC is too 2.9GHz

My PC is:
M3A78-EM
7750+ BE
KINGSTON KHX8500D2/2G x2 (4GB)
TACENS RADIX III 420W
SEAGATE BARRACUDA 500GB 7200.12

, and i couldn't OC my Kuma past 2.9GHz don't worry VCore, if by HTT (FSB), if by multiplier, etc...

So i believe this mobo, or maybe many 7750+ BE don't OC well at all, my next step is when i could, change the mobo or change the processor (i believe the processor is best...)

If anyone else has a similar configuration and say what he do for OC'ing the 7750+ past 3GHz thanks...

Bye!

At the time I purchased everything, I didn't know anything about the chipset on my mobo, or the processor batches, so at this point I KNOW my next purchase is going to be more thoroughly researched so I can avoid these road blocks in the future.

Hey, both of you guys, I also have the Asus M3A78-EM and 7750 and can't make it past 2.9ghz. I'm thinking this is not a coincidence. Anyone else have any thoughts on the subject?

We've narrowed it down to the chipset on the motherboard or a bad batch CPU. My bet however is on the motherboard. Just forcing me into an upgrade at the end of the year lol

Definitely let me know, that would help determine if the motherboard is in fact our problem!

I think it too, but many people with the Kuma and this mobo (and with others mobo too) has the same problem, but with this mobo and athlon x2 no, it isn't the best mobo for OC, but the Athlon II x2 250 OC'ed to 3300 only is much better than Kuma OC'ed to 2900MHz, and the price is very cheap, upgrade the mobo costs more, and the benefit is less...

Bye!

Well, as i supossed the Athlon II x2 250 OC'ed to 3600MHz (i'm probbing stability yet, but it looks fine -prime95 45 minutes stable-), only upping HTT (FSB) to 240MHz, downloading RAM from 1066 5-5-5-15 2.2V to 960 5-5-5-15 2.0V (in bios set it to 800MHz), VCore stock, HT Link 1600MHz (final frequency 1920MHz), NB Frequency cannot change multiplier, so it's at 2400MHz but without problems, and temperatures very, very cold comparing with Kuma, with an Arctic Cooling Freezer 64 Pro máx. temp is 52º C only at full with prime95!!!

I recommend this processor if you could upgrade, with the same mobo and bios 1902 the results are great!!! Super Pi, Everest testing memory is so much fast, etc, etc...

Bye!
