GA-P55-UD5 rev.1.0 problem with randomly BSOD

[Andy230]

Hi all, I have built new pc:
Intel Core i5 750 2,66 GHz BOX
CoolerMaster 212+ Hypher
Gigabyte P55 UD5
Corsair DDR3 2x2GB 1600MHz CMX4GX3M2A1600
Seagate Barracuda 7200.12 500 GB
XFX Radeon HD5870 1GB XXX Edition
DVD-RW Samsung SH-S223C SATA black
Antec Three Hundred
Corsair 650W TXEU

I installed WIn 7 x64 ultimate, all actualizations are up to date, all drivers / Catalyst 10.5, all MB Gigabyte drivers latest version forom web, updated
BIOS to F9 version../ When I started pc i have randomly BSOD. I check the Corsair forum, Gigabyte forum - my opinions is - "incompatibility RAM".
Any suggestion how to solve this problem? I have default setting of BIOS an also I tried manually set up voltage V-core, RAM modules...

What to do? Buy another pairs of RAMs? / KINGSTON 4GB KIT DDR3 1600MHz CL8 HyperX XMP, KHX1600C8D3K2/4GX /

Thanks a lot

The memory that you have installed is not on the Gigabyte QVL so it may not be compatible. See: http://download.gigabyte.eu/FileList/Memory/mb_memory_ga-p55-ud5.pdf
Have you tried using the settings that are printed on the side of the memory modules rather than the default settings?

[Andy230]

Yes, U are right. Those modules are not on the list you posted above, but this list is too old for my opinion. / not actualized/
And also I tried manually set 9-9-9-24, ddram voltage set up to 1,64V, QPI- set up to 1,34V... and I tried to setting up many combination.
And what about KINGSTON 4GB KIT DDR3 1600MHz CL8 HyperX XMP,KHX1600C8D3K2/4GX ? Thea arent on list too, what do U think about it?
Thanks for your time an answers.

The Kingston memory modules are quite popular although personally I prefer the Corsair as a make. I would recommend that you go on the memory manufacturer's website and see what they recommend for the board, that way if you have any further compatibility problems you have more rights to return them. Check out the Corsair first for your present RAM and then the Kingston if they are not there.

I raised up voltage DDRAM - 1,66V and QPI - 1,35V it seems to be solved. I must do some tests /Prime95, LinX, Memtest86+.../
Is it safely for MB or components?

There shouldn't be too many issues with the increased voltages and, to be honest, it seems that a slight increase in voltages seem to solve a lot of memory issues. The only thing to really keep on eye on would be the temps throughout the system as the higher voltages will increase the heat output of the components.

Gigabyte boards are really good at handling increased voltages and I have yet to have one fall over because of this.

Yes, temperatures are good, I have 2 ENERMAX Cluster 12cm FANs intake at front ofcase, and 2 FANs as a outtake 2pc /12cm and 14cm/ both of them are original CASE Antec three hundred included. Temperatures of CPU cores at a Linx after 2hrs at a 3,6GHz OC CPU are 58-62 degrees C.

Sounds like you have cracked it The slight increase in voltage shouldn't give you any problems(unless we actually get a good summer )Good luck with the tests.
