955 & 8GB of 1600

post #1 of 22
Thread Starter 
I am currently running my 955BE with a max overclock of 4.1GHz (205x20) @1.440V.

My motherboard is the Gigabyte 880GA-UD3H (latest revision & latest BIOS) and my ram is 4GB (2x2GB) from G.Skill 1600 running at 1640 (8x205).

While overclocking, and through AIDA64 benchmarking, 1640 @ 9-9-9-24 were faster and less latency than 1333 @ 7-7-7-21.

I went ahead and ordered another set of 2x2GB of the same RAM I have.

I read a lot about the Phenom IIs not being able to run 8GB at 1600.

Can Phenom II users (955 and 965 especially) please give me their feedback? Will I have to run the modules at 1333 in order to keep stability? Currently my NB is at 2200.

Thanks,
ULTRA

I think you'll be fine at the cpu-nb speed with 8gb of ram running 1600Mhz.

Thanks for the feedback guys. I was betting on the raising the CPU-NB should things go unstable.

Why do people then moan all over the internet that Phenom IIs can't do it? Everyone is a noob all of a sudden?

It's runnning great.

EDIT

C2 or C3 stepping? C2 no way. C3 you should probably be okay with some CPU-NB voltage bumpage

My 955 is the C3 stepping. Currently my CPU-NB is at 2200 @ stock volts.

I am going to tinker with it now and find what's the ceiling of stability with 4GB so that when the other 4GB arrive, I have a place to start from.

shouldnt have a problem running 2 sticks at 2600 cpu-nb at auto volts.
maybe with a bump of voltage going to 2700-2800

Yeah I am going to start experimenting with the CPU-NB now. It's the only thing left in my overvlock to get the most out of the system.

Now that the 2nd 4GB are on the way, I better get to it.
