As you can see, its still cranking out the GB/s:

What? ph34r-smiley.gif
It's even running with both cpu and cache downclocked?
It can't be real (at those numbers), there's something unclear
Are you sure you're using a recent aida64?

Edit:
It's the same version as mine rolleyes.gif

Aida64 seems to capture cpu/nb clocks at launch time so they are garbage... look at cpuz in that pic

Or look here, I just ran it again, launching aida on a loaded system. Can't get asrock or memtweak to show me numbers, there must be something else I don't have installed.

These numbers bear out what I see on dual xeon boards with 2400 as well as other chips I have at 3000. I really think there must be something going on in your system - either cache speed or high rate of crc errors.

BTW - my memory settings are 14-14-14-34-2T- AUTO-everything else Even Rampage Tweak is "auto" for memory. Other than "eventual voltage"

SA is +0.350 for 1.2v because of 128G

Yes I have tried per core, individual core and core sync. After everything discovered that I get the best results when I sync the core. My benchmark results are good. Not the best but good enough to be happy.

yea i just noticed my scores at 4300x3 and 4400x3 are lower then all 6 at 4300 but overall perf might be better with 3 at 4400.

With memory speed constant, cache clock makes a big difference in memory benchmarks ...

Yeah, that's more what I'd expect and very nice! thumb.gif

I know but he's also at 3600 cache as I am
There's gotta be something else
Btw:
On my second run of oc since yesterday I've achieved pretty much stable results but with lower voltages than before, 1.20v vs 1.25v cache, 0.98v vs 1.05-1.06v vccsa (though unstable before at higher volts) and 1.075v vs 1.135 vccio.
I'm gonna test right away with a 8h of RealBench just to seal the deal and see if it still holds well.
Otherwise (or in any case however) I'd try to just increase a bit more one (or more) of these 3 voltages in order to see if there's a memory performance gain.

Pretty nice numbers as well even if you had the cache at 3.7 wink.gif
Didn't you install the new one yet?

Very nice but as you increase the speed of the Ram you decrease the latency. Just the nature of the game.

Whats the max system agent voltage most are running i was playing with my ram see if i could get it to 3400 xmp sets it to 1.37 for 3200 and if i set the ram to 3400 it sets to 1.45 seems crazy high.
