Yes, they look like results :p
Beat Kaap when his X's were on air, so that's good i suppose.

I just want some approval lol.

The gpu's have more in them for sure but cpu will top out at 4.9. Used +100mv there so potentially have another +100mv to play with. Could do 1275/1310-1625 with two cards but i think this third card is the worst of the lot. It will only do 1500ish at +100mv where as both the others will do 1625. More voltage may help it i suppose though, it is my lowest Asic card.
 
Guess I'm luck, my 3970X needs 1.4v for 4.8ghz, at least it is bench stable at this, didn't try more because I'm using air cooler...
also I'm using 1600mhz cl9 memories, so not pushing there, probably the IMC would limit the overclock a little bit.

I tried this with my case open and a huge fan blowing air :), it didn't go over 72C

When I finish my waterloop I will try to reach the magical 5ghz.

I'm having troubles guys. I'm finding enabling speedstep makes the pc unstable, like really unstable. Even when im using manual voltage. Any idea why this could be? I'm trying to set up a 24/7 4.4ghz cpu clock with 2400mhz memory.

EDIT

This is with all C states disabled for now.
 
I'm using mine 24/7@ 4.5ghz and 1.3v, I have everything enable, but I'm using 1600mhz memories.
Did you try leaving your memories at 1600 to see if it is stable? I'm not sure if all SB-E can handle 2400mhz, I read somewhere long time ago that some people were having problem with 2400mhz memories and a 3930k/3960x/3970x.
 
Weird, now it appears to be working ok after i loaded my 4.9ghz profile and slowly tweaked each setting down. Speedstep is on and now the machine ain't crapping itself. I don't get it.

Which C states do you use? 3, 6 and 7?

Just put it back on Optimized and it's working fine now. No idea what happened.

That's pretty much how I felt after overclocking my X79 board.

If I went strap and multi my rig would behave oddly. IE, it refused to reset even at bios it would just shut down so I would have to manually keep turning it on myself.

In the end I gave up on strap and just hit the multi. Got to the same place...

Got a feeling I could get higher than 4.7ghz though if I hit the FSB and strap but tbh there's not much point now.
 
So far not found c states or straps help with stability at all - I don't think the underlying hardware quite likes it.

Multi overclocking with c states disabled seems to give the most reliable results, I've also found (dynamic) offset voltage seems to give a bit better results than trying to dial in an exact voltage manually.
 
Does anyone here use the C states? I've got C1E enabled at the moment, but that is all currently. Afraid that changing too many settings will get my back to where i was 30+ minutes ago. I couldn't even get the system stable at 2133mhz and 4ghz lol. Now here i am back to 4.4, 2400mhz tuned tighter than a ducks bottom and things are fine again.
