Congrate pieter, nice freq for lovely GTX580

PJ your physics score is really poor...

Hm. Interesting catch. I'll do some investigation tomorrow

Okay, seems like one of my driver settings isn't okay. I had the same issue here: http://hwbot.org/submission/2199012_massman_3dmark11___performance_3x_geforce_gtx_580_17387_marks

Top 10 in sight ?

It's not the driver issue boss. It's BCLK-RAM subsystem trust me

Cool. So I'll have to use 2133 CL7-7-7 or 2200 CL6-9-6 then

All that binning and only 1100 memory?

This is my one and only Matrix. No binning involved

so Matrix has such crappy mems ?

It's not really the mems. I can run 1250 at -50° no problem, but to be able to run below -140°C I need to go all the way back to 1100MHz. It's more likely to be the IMC. Whether it's GPU quality, PCB quality or a combination, I don't know, but SF3D has mentioned that this problem is only present on the media/press samples (mine's one of them) and no longer on the retail versions.

 

Boris already did 1650/1400 through 3DMark03, I guess it's true.
