Try this calculator for RTL and report back if it's any better than the first. I have left the first version on the left hand side, newer is on right. I want to know how much drift you get on the new version on various boards - don't move the min sep delay on the right hand side. http://www.mediafire.com/file/abr3bwad5cn7485/rtl2.xlsx Later Raja |

| By raja Hey hey mate, long time no see
 I tried clicking on your link but it says the file does not exist. FWIW, I've been using your same formula from your Anandtech P55 overclocking article and it has worked beautifully for calculating RTL's on my P6X58D Premium. Luckily the board allows us to manually set them |

Try that; http://www.mediafire.com/file/hs3dhn4d53ypceh/rtl2.xlsx Media Fire can be weird sometimes. I just tried downloading here without logging in and it worked ok for me. This newer version may be out by a few clocks I think.. |
