What makes a Venice core A64 run Pifast quiker than an Opteron?

333 and then up by 40% (280 instead of 200) makes you ram at 233, so yes, bang on chap.

it's actually 229 with that external clock/multi/divider combo.
I think that it's going to be something in Zak's setup (noard, RAM timings etc.) - might have to run this on my AN8 Ultra/146.

it's gotta be a memory bandwidth issue here guys. My ram wont run anywhere near as fast as that on da_ging's system.

He's got PC4400, and Yamangman's running 3500.

My first test with my opt146 was divider/1:1 250mhz
