Memory clock discrepancy between CPU-Z and 3D Mark 11

post #1 of 5
Thread Starter 
3D mark 11 claims my speed is 667 mhz

Cpu-z shows it at its proper 800 mhz

My motherboard is showing it at its rated speed.

Is 3D Mark wrong? It always shows 667.

Maybe because the Default SDP speed is 1333mhz (666.6x2)

and the XMP profile is 1600mhz(800x2), so it could be 3dMark only detects the default maximum SDP speed, but not the XMP Profile that may be activated.

What speeds do other program show?

What other program could I run to check for RAM speed?

yep, futurmark sysinfo read the jedec speed, not the really speed.
Use CPU-z to know your ram speed.

Thanks, it must be an issue with 3d mark. It reads properly on other programs except 3D mark 11. I even overclocked the RAM to see if that would change what 3d mark says. It didn't.
