Huge disparity in memory clock readings


Apr 22, 2009
Hi everyone, this is my first time posting a question here but I read here often.

I have an Athlon X2 5200+ Brisbane (2.7 OC'd to 3.105) and 4GB of G.Skill DDR2 800 memory. I used the FSB to achieve this OC so the memory is overclocked as well (FSB from 200 to 230). However, the memory readings appear to differ from one source to another. In the OS, my memory reads as ~444MHz, whereas in memtest it appears as 517MHz. That's a substantial difference in reading and I'm hoping it's not a stupid question as to why this appears this way? Also, I am pretty new to OCing memory -- with the given stable settings I currently have, should I try to do anything to any of the timings and if so what would be the best things to try?



In case these items are relevant to either question:

Motherboard: ECS A780GM-A
Processor: Athlon X2 5200+
Memory: 4GB DDR2 800 (only 3GB active atm; 32-bit OS until Windows 7 comes out)
