Hi there first post on this thread, please be gentle
I'm having issues with overclocking on a DS4 with the F3D BIOS, I have problems with overclocking RAM, I have 2 sets one is Geil 6400 Ultra 4-4-4-12 and the other Kingston 8500 5-5-5-15.
Strange things are happening the other day I got 371 X 9 with the X 3 multi on the Kingston ram, this was 9 hours memtest stable with timings of
5-5-5-15-10-10-10-0-10
Then after trying to up it to 375 I got no boot so I reduced it one by one and now it will only run at 366 X 9 on the 3 ram multi.
I thought is it the CPU so I increase the ram multi and lower the fsb to reduce the CPU speed no matter what I do it will not run on the 3.3 or 4 multi unless the total ram speed is below 1050MHZ yet it was stable at over 1100MHZ I have also tried voltage options but nothing at all makes it go higher, from 2.2v upwards makes no difference at all.
Slackening the ram timings also makes no difference. I am confused though about some ram settings I know what the first 4 settings do ie 5-5-5-15
but the others that follow ie 5-5-5-15 then the next 10-10-10-0-10

What is slackening the last timings is it higher or lower? I have tried as low as 8 and as high as 15 but the settings of 10 make the best overclock.

I have read quite a lot on here but I cannot find anything specific to my problem, I don't think my CPU is the best there is but what is confusing is when I increase the multi on the ram to 3.3 or 4 I cannot get higher ram speed. I have also tried increasing the othe voltages but it doesn't help.

I cannot find what would be the best current BIOS for the DS4 either, any help or idea's would be appreciated it's doing my head in I've spent 60 hours this week and I'm no closer to finding out whats wrong.
