F3-12800CL9D-4GBNQ + GA-P55M-UD2 + i5 750

[ernie]

DDR3: 4 x F3-12800CL9D-4GBNQ
Mainboard: Gigabyte GA-P55M-UD2 Rev1.0, BIOS F11
CPU: Intel Core i5 750

I get BSsOD every day.
Memtest86+ gives me errors no matter how I place the modules on the mainboard.
I loaded the safe defaults in BIOS, I do not OC, I just need a stable system.

Can someone tell me the right BIOS settings for my G.Skill-modules, please?

Another weird thing: As you can see in the pics I attached all 4 modules are supposedly the same model, yet Memtest86+ and cpu-z identify only two of them as 12800 and the other two as 10700. Also, they show as 2GBNQ as opposed to the sticker.

Can someone help me, please?

Set it to DDR3-1600, 9-9-9-24, 1.50V and see how that works.

Looks like you purchased the modules at different times, so the programmed SPD is slightly different. You don't need to worry about it since you need to use manual settings anyway. Also, 2GBNQ is correct, that is the model of each stick.

Thank you

I did. See new pic, please. I will run Memcheck86 after I made this post and report back.
In the BIOS settings bank 1 and 2 have different settings for tRC (40:34), tRFC (88:130) and Round Trip Latency (46:44). Is this correct? Or should the values be identical?

Yes, I did buy them at different times. The troubles started after I stuffed in modules 3 and 4.

The new pic is spot on. Is the system stable?

I ran Memtest86 for several passes (around 4 hours) and did not get any errors.
So far, so good. Now I am running W7x64 again and I hope I don't get any more BSsOD.

Thanks for your help!
