For those with a 980x what CPU settings do you use for 4.2ghz

What cpu do you have

 I am about ready to give up. Best I have seen is 78 Gflops. I have my ram at 1600, uncore is at 2400. Redid all my volts and still no go.

 
Your Uncore is the reason. Try getting your Uncore to 3200MHz. The Gulftown generally flakes off around 4000MHz

Hi guys
 
reporting back after some serious headhaches to figure out what was wrong on my 1st attenmpt (page 6)....
 
first, I have to say I'm using only one 12Gb tri channel kit for the moment, will modify my sig accordingly asap ;)
 
next... as I'm quite new to Intel (changed my quite old opteron setup like 2 months ago) and left many things on [Auto] in setup, except memory that was set to XMP (because it was the only workaround I found for my random disapearing ram, now I know that the problem is SPD and the built-in command rate setting... must use 2T to solve this problem)
 
ok, so after a few hours of testing, I'm reporting back with quite a good news:
 
[see post #250]
 
this needs more tweaking to hit the 80+ Gflops, but I'm on my way (will try to tweak uncore to see if it helps)
 
BTW, this board is weird, I'm not able to go 2:14-16 ram ratio (I know the ram is capable of 2000MHz+ @ 1.65v), cpu-z and memtest86+ always report 2:12... Must add that auto setting on QPI link will always set it to the minimum, I set it to 6.x manually now....

oops, ImageS automatic resizing
 
so here we go again:

never mind

Welcome to the forums Josemt10 and Welcome to the X58 Stability Club.

Does memory speed make that big of a difference in the GFlop speed?

Kram, Remember that the uncore frequency is using a multiplier on the DRAM. Basically assuming he is using a 1.5x multiplier on his gulftown, @1333MHz his Uncore is only 2000MHz! Even if he was running it at 2X he would be at 2666MHz and I am running close to 4000MHz. The Uncore controls everything besides the Core which I assume includes the L1 and L2 cache. It will slow down all the transactions to and from the core.

I'm going to take some ram out of another machine and try it again tomorrow morning. 4.2 should be getting around 78 - 82 Gflops, right?

Hum, in this post here you commented the GFlops were low for his cpu speed.

The Gflops still look very low for your clocks...

Sorry about the pic. I goofed on the ss somehow. Hopefully you will let it pass.

Yes and I am suspecting that his uncore is low as well.

Nice job vince6984, welcome to the club.

sorry to clutter the thread but does the skull in the signature's say 4.2 + MHz?

Appreciate you running these test.
 
Kind of hard to call that stable. They did pass the test without errors though, just not optimized for the best performance.
 
What would you call it? Stable or not?

I would call them stable but we probably would want to add a separate ranking by Gflops.

Yes it does.
