Thread: Tweaking DFI X38 and E8200 to 4GHz

Could you post a BIOS template with the settings you are using now?

Hi, I'll get on that asap, I've been so busy with work its nuts, would you say then at 3.6Ghz I've probably reached my amateur OC limit then? I though it would be possible to breath on 4Ghz with this CPU? or do I need to ditch the quirky DDR3 to get more in sync with my capabilities?

Thanks very much for the responses , hopefully we can pick this thread up when this board get sorted - I still think I should be able to get the board stable at 3.8Ghz (maybe 4) - its stable at 3.7 in single channel mode so I dont think dual channel RAM will make a difference to overclocking?

I've merged all those posts together. If you don't know what you are doing, my advice to you is to leave the GTL Ref setting as disabled and go as far as you can without it, this will simplify things a lot. If you really want to accurately tweak the GTL ref settings, you are going to need a good quality DMM and measure the voltages yourself, this is the only way to do it. The charts that are posted in the BIOS guide were done by DFI...

i found that 3.6ghz was when i really needed to start upping the vcore to keep it stable with my 8200. not 100% but from what i can recall i needed about 1.25v for 3.5 1.3v for 3.6 and i think it was 1.42v for 4ghz 450 is about the fsb where you might need to start playing with the chipset to get it to boot too. have you tried dropping the multi and just working on high fsb ?
