Asus M4A87TD EVO & F3-12800CL9D-8GBSR

post #1 of 7
Thread Starter 
Hi,

I have a new system with an Asus M4A87TD EVO, 8GB of G-Skill Sniper, and a Phenom 840. I've been having issues getting the ram to run stable at stock speeds (1600) I can get it to run alright at 1333, but cannot OC anything else (CPU, NB, etc) and keep it stable. If I want to do any CPU or NB OC I have to underclock the ram (1200 and below.) I've fiddled with voltages and timings for hours, trying to find a good combo to no avail, any helpful input would be much appreciated. Thanks in advance.

faulty ram probably. You should also try increasing cpu-nb voltage. If that helps, then you have a weak chip.
Since those sticks are newer than ripjaws, you should also update the bios.

You sure everything's set to rated (1600 9-9-9-24)
Have you tried a small boost in the CPU-NB voltage?

Have you read the motherboard manual in case the mobo manufacturer recommend you run the RAM in certain slots on the mobo? (which ASUS does sometimes)

I've not only updated to the latest bios, but i've also tried different ram slots, made sure ram timings were as rated, and boosted the cpu-nb as high as I felt was was safe, currently running it 1.2v, i've had it up to 1.4 with no better result.

Noone around with a mobo that accepts ram this fast. so thats out of the question. the ram tested just fine, when I ran memtest.

at least lower the latencies and run memtest again. That way you will definitily see your ram is ok. Next thing, chip. Probably it's at fault.
