F2-8500CL5D-4GBPI-B with P5Q - Big problem

[lumat83]

Hi everybody

I'm new here, and I'am a new GSkill Consummer.

I've a problem with 2 RAM DDR2 "F2-8500CL5D-4GBPI-B" on a motherboard Asus P5Q (CPU Q9550).

Since I installed these new RAM (I had PC6400 before), when Windows is loading, there is a blue screen (with some memory adress
and an errors on the ACPI.SYS).
After, the PC reboot, Windows launch a repair of the system without success ...

My bios is updated to the last version (2208).
I set the RAM timings manually to 5-5-5-15 and their Voltage to 2.1.
I tried to set memory to 1066MHz manually.
I tried with one RAM and the other
I increased the NB voltage to 1.3

Maybe one Ram is wrong but the two at the same time .... It's strange !

Is there an possible incompatibility between the motherboard and these RAM ? Or maybe there are some other values
to change in the bios ?

I don't know ... But it's impossible for me to load windows.


Can you help me ?


Thank you for your help

Should have no problems at all. Try testing one module at a time, or memtest each stick to see if one may be defective.

Thanks for your answer

I tested the two sticks, one at a time :

Always the same problem during Windows is loading (blue screen with memory adress, reboot ... ). Sometimes after the reboot, my computer don't start anymore.

I launched memtest and I've errors on the 2 sticks : one work for some minutes only and the other crash after 97%

It's strange for me but it seem that the 2 sticks are defectives ?

Strange, but go ahead and send those back for new replacements and hopefully the new set will be better.

Thank you

same ram

hey, I have the same ram, just got it today. My question is what are the differences between "DCT-1" and "DCT-0" and "Both" in DRAM Timing Mode?
I took couple of pics of my bios. I just need a confirmation if they are ok.
I have Phenom ii x4 940 black am2+ cpu.

DCT 0 and 1 are the memory channels. Simply use "Both", as you have currently set. This will keep both channels active should you want to use all four slots.
