I wanna prove to the world that Opterons can hit the 3ghz mark, but the only thing that's stopping me is the RAM. My motherboard (Iwill DK8N) does not support _any_ OC'ing features at all, allthough it has the handy PCI/AGP lock.

At the moment I can get to (225 x 12) 2749mhz stable with my crappy pc2700 registered ram, using clockgen. I need to get HT to 250 to be able to hit 3ghz, and to do that I need a way to get the cpu clock/ram divider to be smaller (either hard or softmod). I've tried a64 tweaker but only a little, every time I change memclk freq the results show in memory benches but it still locks up at ~2750ish. I know the CPUs aren't the problem, its deffinatly the RAM. (Maybe im using wrong a64 tweaker settings?)

If there is absolutly no way I could change the memory divider, or whatever method wouldn't work with my RAM, I am upto buying a new mobo/ram to get this to happen, but as of yet I havent seen any registered ram above pc3200 (ocz made 3500 but its discontinued) and no opty mobos that support overclocking.

Hope you can help, Zxcs

Thsi is one of the reasons why the FX migrated to 939 pin. It doesnt use ECC mem. ECC mem is not made in speeds, latencys or the such to oc worth a damn. To be truthful I dont think it can be done. Not due to the CPU's but from other supporting hardware and therfore lack of things to get the job done from that hardware. Sorry :(

The ASUS SK8N has overclocking features, you could look into that.

The overclocking menu in the bios looks a little complicated though

I'd say ram is your limiting factor, though. If your board allows for loosening of timings, then go for this http://www.newegg.com/app/ViewProductDesc.asp?description=20-146-940&depa=1


There's a chance it could hit 250MHz with, say, 3-4-4-8 timings. A chance.

Oh yea, also note I'm trying it with two processors, buying a 1-proc mobo would be good for getting the clocks but wouldn't be practical for me.
I bet I could do 250 with the OCZ 3500 chips, hard thing would be finding a place that sells them.
