memOK problems

1234543212345 · 13 Sep 2010 at 02:03

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?

If there are any errors when testing with memtest it would indicate faulty ram.

Try testing each memory stick individually, with memtest, and if any come back with errors then i would RMA them back to the place you bought.

I think he's saying he gets errors in memtest only if he switches his pc on without having ran memOK.

Sounds like a dodgey mobo to me

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

I'm running an i5 760 with an Asus P7P55D here. I did have a problem with some Corsair Dominator, but I had a kit of 3x2gb XMS3 left from my i7 build which is working fine atm ( only using 2 sticks )

I take it it's the 2x2gb kit you have ?

What speed are they rated at - 1333 or 1600 ?

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

i have bought a i5 760 , a asus p7p55d and 4gb of corsair dominator today and if i run the ram at 1600mhz as its rated to i also get blue screens left right and centre.

currently running it at 1333 and so far it been fine.

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

DRam Timing set to 2T ? Sometimes it defaults to 1T on AUTO.

Could you post a photo of your AI Tweaker page, so we can see what the settings are ?

Were the 2 p55-ud2's returned because of the problems you've described ?

Do you have the time to do what bifday2k suggested ?

1234543212345 · 13 Sep 2010 at 21:27

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.

I've just built an i5 760 pc with a P7P55D-Pro motherboard, and 4GB g.skill ripjaw memory. No problems at all with the memory so far (touch wood). Not had to use the MemOK button.

The ram was initially set to 1333 by the motherboard, but I'm now running at 1600 using the XMP profile settings in the bios. Passed over 4 hours of memtest 86 and an overnight soak test of Prime95 blend tests.

Do you have the latest bios? I know that some of the more recent bios revisions have improved memory compatibility.
