Hello everyone, I'm new to this forum as far as posting but read it all the time. Lots of good info and people here.

I have been reading over the last couple of days all the pages of this thread. I have tried many of the things I read on here but still having issues trying to OC my E8500 on UD3P board.

Let me just give a short explanation of what is happening: I have used EasyTune 6 only to try and see where it sets voltages on a given OC speed, but do all my OC work in the BIOS. So if I choose the standard OC in easytune of 4.05 (the number 3 button), it works and is prime stable for hours and hours. However after setting that OC and going into to bios to tweak it or change it, I run into a brick wall. If I change anything even slightly it either won't boot or isn't stable. For instance, I tried changing the ram from 2.40B to 2.00D to put the ram at 1:1 and no boot, or boot and then blue screen. I would think that the voltages and timings easytune sets at this 4.05Ghz OC would be close enough for the ram to run at 1:1. Oh I'm sure the voltages need tweaking, but c'mon is this board really that finnicky when it comes to voltages/timings? I have also tried increasing the fsb slightly and get the same results, either no boot or boot and then blue screen. But I have a feeling that the voltages are the problem. There are so many settings that I really don't know what to increase and what to lower. I have tried many user settings and tweaked them up or down and still having issues.

I would like to get an OC of 442 with a 9.5 multi which would put me at 4.2Ghz with ram at 1:1. I can boot into windows with these settings, but it wont even run prime for more that 5 mins without errors. I would be open however to a lower multiplier if I can get around 4.2Ghz or above stable.

I have Corsair Dominator 1066 ram. Running F6 bios, should I flash to F7?

Can anyone give me a template of settings to try, even if they are a starting point to try and reach this OC? I know my E8500 is capable of it because I had it in an SLI board running at 4.2GHz 442fsb and 9.5 multi. I also have another rig with an Asus P5Q Deluxe, and another E8500 running at the exact same OC 4.2 442....etc.

Here are the last settings I tried with no luck:
