Why? My mobo is the GA-EP45-UD3P, CPU is q9550 @ 3.4Ghz. Do I have to overclock my RAM just to get what I payed for?

Your RAM is downclocking?

Is your RAM 1066 for sure?

I know if you mess with your CPU core clocks in the BIOS it sometimes will mess with the RAM slot speeds as well.

the serial number say 1066 and my receipt say 1066. Without changing settings in the bios it says 800. when I OC my CPU 800 is the only setting I can have it on without overvoltaging the ram.

EDIT: By the way, your avatar is hilarious. Just thought I'd get that out there.

Hi.

Enter to the BIOS and configure all spec of ur RAM manually.

The highest OFFICIAL DDR2 RAM speed is 800MHz. Anything over that requires you to manually set the RAM speed, timings, and voltage settings in the BIOS. That's completely normal. Most motherboards require you to manually set RAM values for RAM rated over the DDR2 standard 1.8v. They have to do that for compatibility reasons.

+1^ for everyone whos posted and thanx about the avatar!

Update: I would try what the above posts say as far as manually setting your RAM speed.

What values do I set it to? What values do I change?

I've set the speed to 1066 and the voltage to 2.08v but I don't know how to set the timings and when I boot it gives me a blue screen.

Tried 2.1v and 2.2v but neither worked. Still don't know what to do to make this work.

Hi again.

Ur BIOS is something like THIS right?

Can u see the CAS Latency, tRCD, tRP, tRAS?, Change that values to the specific for ur RAM. Usually are 5-5-5-15 but check the specs of ur RAM for confirm that.

Ok. Does it change when you change the clock speed, because it is already set to that by default.

It turns out it didn't work and now I need to know how much voltage the RAM needs to boot properly. I set it at 2.1, 2.2, 2.28, and even 2.3 and nothing worked.

The specific for ur RAM, that I think is 2.0V-2.1V. If that doesn't work the problem about compatibility between ur RAM and mobo.

Great, and now even when I set them to 800mhz and get to the log in screen, it won't accept my password.
