you need to check your DRAM divider setting. if it's 03/2, of course you will get DDR400 if you set the HTT speed to 300MHz.

basic overclocking.

what the highest mhz u can get with ur TCCD?

intel's memory controller limitation

and forgot to mentiond earlier..310 @ 1T 

my tccd can't even pass 260 mhz with 1:1 divider with timing 3-4-4-8,1T @ 2.85 vdimm

why why why?

is it my mobo limitation?

even with 289x9 for cpu while i set my ram divider to ddr333 it can't boot also 

but magiara proc is not opty one...and mine has no problem on memtest and loading windows...play games (not too intensive kinda game) and stuff...but only failed when i ran the prime with large fft...

but we have to remember that for a64 and opty...the mem controller is built into the proc itself...so most prolly ur venice has a damn good mem controller whereas ur opty has a not-so-good mem controller...so, we just cant assume that when the A ram is doing great on this proc, it should oc well on other proc as well...that's just not the case bro

ur tccd...which one huh?the ocz one ka?

so...in this case, since ur ocz is binded and guaranteed to work at ddr600 at stock..it should be able to do so regardless of the proc...hmmm..rma? :

Different K8 will need different memory timing setting.

I'm not refering to the SPD timing, but the memory controller's timing itself.

wahhh..manage to get 2.9 ghz with 1.45v only..well done mate..

izzit prime stable?

after found pls tell me oso

try my gskill la..hehehe.. i think TCCD and TCC5 will giv diff result

For me low RAM speed + super tight timing is pretty easy. But once it reaches 240MHz above, it started to become unstable. Maybe my RAM is too hot?

okies..thanks for sharing..i'll try it..
btw, how to now izzit GB or not ?
