Hmm, try running each seperatly for a few passes of test 5 - and post what it says your mem bandwith is for each stick: example 5042MB/s.

Was everything else at stock settings? NB etc

No I had left all my other settings alone, I was only running small prime. Regardless I think Im done messing with things for the moment. I have no particular urge to bump it up any higher.

One thing that I have noticed since I updated the bios is that C&Q is really buggy now. Sometimes is stays in the p1 state no matter what. At one point it was stuck in the P4 state. The decrease in voltage in the p1 state is also a lot less than before the bios update. I downloaded the updated PhenomMsrTweaker, diabled C&Q in bios and set a custom plan - seems to be working much better now.

I wonder how low I can set the voltage when its at 805mhz, currently at 1.2v

I'm running Memtest 4.1 Test 5 with both sticks and I'm getting mem bandwidth of 4907 MB/s.

Ah well the reason I asked is that when I had 1 bad stick, 3 were running at 5042 and the bad one ran at 4906 (each tested individually). 2600NB, 1600mhz, 7-8-7-24

Oh...Well, were you getting errors by running all of them together? I would think that having both of my sticks in together and having no errors means that both sticks are working fine. I don't want to go back into my case if I don't have to...

Anytime I run ram over AMD's DDR3 1333 IMC I get errors..

I just run my ram at 1333 with tight timing which is faster than 1600 at 7-7-7-24.

Yes I was getting errors, however it did pass a full round or 2 sometimes with all sticks, it was much faster getting errors with individaul sticks.

If your sticks are passing I guess keep bumping up your volts until you hit your comfort lvl. If it is still not stable at that point I would return the mem and get a different set.


The x6 IMC's seems to have adressed that issue, after the bios update i am able to run mine at the rated speed of 6-8-6-24 1600 with no problems. Before the update I could run 7-8-6-24 1600. I have not tested lowering any of the timing past that except for the cas - cas 7 or below = no boot.

Yeah, I heard it was better.. but since its still rated at 1333 anything over that is overclocking. I'm sure better ram will help with IMC conflicts.

You're not losing anything running your ram at 1333 with tighter timing. Which has been proven to be faster than 1600.

I saw that article, it was really interesting. It seems depending on your NB speed 1600 6-6-6 trades blows with the 1333 5-5-5.
