Hi all,
Here are my specs.
Core2Duo 8500
G.Skull F3-10666CL9D-4GBNQ, 4x2 GB, stock freq 1333 Mhz, 9-9-9-24 lat, 1.5v
9800 GX2
Custom watercooling for the CPU, GPU and MCP
750W Corsair
With everything set to defaults in the BIOS (FSB 333) I was getting a read speed for the memory of 7700 MB with Everest.
When I was trying to OC the CPU with upping FSB I quickly ran into stability issues after 350 FSB which was equal to 3.4 Ghz CPU and 1400 Mhz for the memory. At that speed the memory was reading with about 8200 MB/s.
I though the memory was holding me back and strapped it down @ 1066 Mhz. Now I increased the FSB to 390 which put my CPU @ 3.7 Ghz with an absolutely stable system ( played games for a week with it now).
The thing is that even with FSB 390 my memory is still underclocked because it is running on 1248 Mhz now. So I expected results slightly lower that stock reading speed of 7700MB/s. But to my absolute amazement Everrest showed 9005 MB/s reading speed!! This is way over the 8200 I was getting even with the memory on 1400 Mhz! Write and copy speeds showed just as dramatic improvement. I changed timing from 9-9-9-24 to 8-8-8-22 but this actually made insignificant difference.
There is something I don't know here and I am really curious to find out.
Thanks to all try answer!
