I have a i5 760 and asus p7p55d pro mobo and corsair xms3 ddr3 ram.
Now when i turn my pc on i have to press the memok button if i want it to work otherwise i get bluescreens due to memory management and loads of errors on a memtest, the problem is have to do this everything i leave my computer turned off for a few hours, it works perfectly for days once its turned on, just when i try turning it on after a few hours i have to do the memory compatibility tuning, WHY? I have tryed setting the ram up manually in bios and saving the settings and also underclocking the ram all to no avail, also updated bios to latest version, how can i get this to stop?

I hope its not a faulty motherboard i've just rma'd 2 gigabyte ga-p55-ud2's, went for a more expensive one this time, i was hoping i had just missed doing something it says go into bios to save memory settings and i save and exit the bios, i think thats what it means. Does anybody else have the same motherboard to offer advice

1600MHz, running at 1333MHz cause of the 133MHz base clock, did have it overclocked to 1440MHz (or about) for a 3.8GHz cpu oc.

Is the ram installed in the 2 blue slots on the board ?

I take it the ram was set to 9-9-9-24-2T, with everything else at AUTO in the DRam Timing Control section ?

Were you only getting the problem when you were overclocked at 3.8ghz, or are you getting it with everything on default settings, cpu at 2.8ghz ?

yes the ram is in dual channel mode.
It is rated at them timings and a manually entered 9 9 9 24 to try and help rest are set to auto.
I was getting the problem before overclocking and with everything set to default

i'll try setting it to 2t later, they where at default, most things at auto few voltage settings are shown i think but they all seemed alright, i'll takea pciture tomorrow.

No the p55-ud2's where returned because of different problems, first didn't post, second 2 chips burnt out (from the mosfet) which means it could have damaged the cpu or ram but they both seem to work fine once i pressed the memOK first :s. When i run a memtest before doing the memok i get loads and loads of errors (thousands in the first few seconds) then when doing it after doing a memok it comes back without any errors atall.
