F3-10666CL7D-4GBRH and ASROCK P55 Pro/Gigabyte P55-UD3

[spilja]

Hi,

I bought a new computer and first it was F3-10666CL7D-4GBRH and ASROCK P55 Pro MBO. Installed Windows 7 and everything was fine until the first time the computer completely cooled off (ie it's been off for 4-5 hours). After turning it on completely cool it would either freeze, throw MEMORY_MANAGEMENT BSOD or boot into Windows, work for a couple of minutes and then throw the same BSOD again. Memtest gave thousands of errors. After restarting for about 10+ times, it would heat up enough and it worked flawlessly until it got turned off and cooled completely again. Mind you, when it got warm memtest showed no errors.

I took it to the shop, they kept it for a week and came to the conclusion that the RAM and the MBO are incompatible and switched the MBO to the Gigabyte one in the title. Apparently they installed Win XP, ran 16 passes of memtest and everything was fine apparently. I took it home yesterday, installed Windows again, it worked great. Turned it off in the evening, turned it on again this morning and it's the same exact issue as before - thousands of errors in memtest (didn't have the time to wait for the computer to get warm).

Any ideas what the problem could be and how to solve it?

[G.SKILL]

in fact, we don't think there is incompatibility with this combination
we tested the two combination and didn't find this issue
Would you like to test one stick at one time?
and try to increase IMC voltage a little to see if it helps

what would you recommend the settings would be? (for the gigabyte board)

also, could this be faulty ram? like a cold solder joint or something?

thanks for the quick reply

[G.SKILL]

we're not sure if it's defective, so we'd like you to try one stick first
for the BIOS setting, you have to set 7-7-7-18(tCL-tRCD-tRP-tRAS), command rate 2T, DDR3 1333@1.5v and IMC voltage(or CPU VTT voltage) to 1.25-1.3v
please let us know what your result is
thanks

I've set the settings as advised, and I've let the computer to completely cool down to see whether my problems will reoccur

Btw, shouldn't the tRAS be 21 and not 18 for this RAM? Also, command rate 2T, I could only change it to 1, 2 or 3 so I set it to 2, could this have been an issue? Because the previous settings alredy were 7-7-7-21

[spilja]

acutally, could you post the whole configuration of the Gigabyte p55-ud3, core i5 750 and this ram? If it's not too much trouble of course

thank you very much, i'll try it out

[spilja]

the system seemed fine last night, no errors in memtest and worked great, I turned it off


upon booting it this morning, I still have the same problems - the computer booted completely cooled and trying to boot up Windows 7 is impossible - I get a BSOD almost immediately after the startup logo, and it's different BSOD's - IRQ_NOT_LESS_OR_EQUAL, PAGE_FAULT_IN_NONPAGE_AREA, win32k.sys, ntfs.sys etc

a similiar thing has happened with my previous board, except that I'd have slightly different BSOD's - IRQ_NOT_LESS_OR_EQUAL or MEMORY_MANAGEMENT.

with the new board my Windows get corrupted after a couple of restarts and I need do the startup repair, but after a while I can boot up normally - once the system is warm. i can't even do the startup repair properly sometimes as I get another bsod

unfortunately, I can't try one stick of ram at a time, as I have the whole computer under warranty.

what I'm left with is trying with new BIOS firmware, but I doubt it will do any good as it should be working with the current one, as has been stated.


My guess is I've got a bad stick of RAM, any suggestions? I don't think it's anything else, the board has been changed already.


What really confuses me is that it works ok once it gets "warm" enough.

[spilja]

what should i set the vcore to? it's currently set to auto. i set qpi/vtt to 1.25

[G.SKILL]

Vcore and qpi settings are fine
if there is still problem, please contact with your local store or us for replacement
thanks
