RAM latencies will not stay set. please help

[etdavenport]

I am currently running an MSI k9a2 cf-f motherboard with a Phenom II 940 CPU. The last Ram I had would not work at 1066 at all without errors. I have been setting all the timings manually voltage etc. Not overclocking. I have tried the Ram recomended by MSI and still no luck. I finally Decided to try G.Skill pc-8500 because a lot of threads have said it works with my board.

BUT HERE IS MY PROBLEM:

I set the timings in the motherboard to 5-5-5-15 2.0-2.1v as specified my manufacturer. When I boot the computer and run CPU-Z it shoes that somehow my Latencies have been reverted to 5-5-5-29!?!?! I cannot get the tRAS to run at the correct speed no matter what I do. but the memory does run at 1066 with no errors. It will also run at 1:2 [800] at 4-4-4-12 no problem. Is it my board? is it the ram? Please help!!

Are you sure it's the RAM? Did you run Memtest?

Did you try one stick of RAM at a time?

You say you have it running at 1066MHz but you have 5-5-5-29 instead of 5-5-5-15? It sounds to me like things are working fine. I'm not sure what the issue is?

RAM is rarely what bottlenecks a system anyway. Generally it's the CPU or the video card.

I figured it out. For some reason my board is setting things 2 positions behind. In other words: if i set the speeds manually to 5-5-5-15, the board is trying to set them to 5-5-5-13 which is outside the allowed latency parameters so it is defaulting to auto. I set the timings to 5-5-5-17 and it then registers at 5-5-5-15 which is the correct speed for this ram. Weird... Its working now, but this is a strange issue my motherboard is having.

"The last Ram I had would not work at 1066 at all without errors." yes I did run memtest on the last RAM i had installed. It came up clean at 800mhz 4-4-4-12 but at 1066 5-5-5-15 [which is the rated speed for the ram. ] it would throw errors.

Either way. 5-5-5-29 is not acceptable. im not trying to overclock here, just get the memory to run at its registered speed.
