Definately a high performance board but should have a sign attached to the box........

Looks pretty good but overpriced for now old tech with AM2 on the way.

AM2 ain't bring much to the table from the early reviews etc

And if you look how cheap the really good DDR1 ram costs now is the time to buy socket 939

nice eav2000, i like this format. I dont think you would be aloud to do it aywhere else .
I really cant wait to see those 06 scores when its running flat chat
youll get th nice position on orb i bet

Yeah all the juicy info is at the top of thread instead of all over the place

Added some stock 256MB BFG 7800GTX scores to above post

Hmmm, I'm finding CFX3200-DR needs more vcore to the cpu to get same prime95/stressprime 2004 stable clocks than DFI NF4 series ?

I'm needing 0.1v more vcore windows on CFX3200-DR than on DFI NF4 for my Opteron 146 which did 3000mhz at 1.42-1.47v on DFI NF4 Ultra-D now needs 1.52v on CFX3200-DR ?

Same Opteron 146 CAB2E 0540FPMW on same water cooling setup = Corsair Hydrocool 200 with s478 to s939 adaptor which gives very consistent and repeatable mounting pressure every mount as you can see from below pic.



DFI NF4 Ultra-D R.AD0 = 3150mhz max 32M at 1.616v
DFI CFX3200-DR R.A00 = 3100mhz max 32M at 1.616v

Wonder if it can come down to memory settings on this board ? Might try a remount of the waterblock.

Swapped out my 146 CAB2E 0540FPMW cpu for my 148 CABYE 0543FPMW for the higher 11x cpu multiplier and came across a weird thing not sure if it's related to the Odd Divisor Correct (i don't even have it enabled) outlined at http://www.xtremesystems.org/forums/...ad.php?t=95860
When i set speeds to 11x 274HTT with 180 divider A64 Mem divider helper says my ram should be at 231mhz. But in memtest86+ v1.65 bandwidth reports 2943MB/s which i thought was way higher than usual.

So i boot into windows and see that cpuz reports my ram @251mhz 2-2-2-5 which would be consistent with 2943MB/s memtest86+ bandwidth reported.

Click on image for full screenie which includes A64info reporting ram should be 231mhz as well.


I see i do have an even number memory divisor of 12 as pointed out in RyderOCZ's quoted post.

edit: Exception to the rule:
okay seems the exception is the 11x cpu multiplier when using 180 divider the memory is probably indeed running with 12 divisor meaning what cpuz v1.33.1 or higher is reporting for mem speed is indeed the correct mem speed ?

Bachus believes it isnt an exception just fact that at 11x and 180 the mem divider is for a fact 12x http://www.xtremesystems.org/forums/...2&postcount=96
About to test if it's truly 251mhz or 231mhz


edit2: Ran 32M and definitely the ram is running 251mhz at 11x274HTT with 180 divider the time of 23min 54s is spot on for the ram it seems.
