Hi everyone, this is my first overclock and first post on this site so please tell me if I have missed out any useful information. I am attempting to overclock an E8400 processor on an Gigabyte EP43-DS3 board, I have 4GB of Kingston RAM in 2x2GB DIMMs. I have included my BIOS settings below:
Motherboard: EP43-DS3, BIOS F9
Cpu: E8400
Ram: 4GB Kingston 800Mhz
With these settings my computer starts up fine and im able to log in, but when I run Prime95 I always get an error on at least one of the workers saying:
FATAL ERROR: Rounding was 0.5, expected less than 0.4
I have also taken some screenshots of CPU-Z to show you:

As you can see I have overclocked the processor to 3.6GHz, and that has upped the RAM from 400Mhz to 480Mhz. Quick question: why has my RAM speed increased? I havent actaully changed of the RAM settings in the BIOS.
The error I get from Prime95 is apprantly from a problem with the RAM but I cant sort it out, any help would be greatly appreciated. As I said this is my first attempt at overclocking, I have learned what I can from this website and others but I could really use some guidance on how to stop that error from occurring in Prime95 and how this overclock can be made better.
Thanks in advance
