2x 7990's & 3770k?

post #1 of 9
Thread Starter 
I bought a 7990 recently & i've pretty much had a good mess with it now?

stuttering seem's to be sorted apart from the odd game, it will do it after loading to the next level? I just hit high performance setting in CCC & it goes back to normal,

I did disable ULPS but for some reason it just seems to do it still, no biggy I can live with that!

anyway I just ordered a second one as they are on offer & its due on Friday,

I didn't really think this through properly lol, will a 3770k @ 4.7ghz be a big bottle neck on them running @ X8/X8.

I plan on watercooling them asap but im looking for bios's with unlocked voltage, As far as I can tell none of the reference malta's allow it?

would be nice if all the 7990 malta owners here could tell us there max voltage? mine is only 1.2v.

If anyone on here is running 2 7990's in X8/X8 could you post some bench's if possible?

Sorry I can't help much, but I'm interested in how it'll run. Can you post before and after benchmarks?

I'd delid that 3770k and whip it up to 5.0GHz. Judging from your voltage at 4.7 it should be possible. That is if your sig rig info is correct.

well im not to keen on delidding it? I can do about 4.8ghz but I need a lot more voltage & the heat soar's after that?



here's a heaven benchmark before?



ill post one after? second card is delayed till Friday as they have none of the free PSU's that you get with it in stock until then! its from SCAN

only thing that's different in my sig is im using only 16gb ram & not running 3 display's atm,ive sold one of them with the fun box system & im getting new bezeless ones around crimbo!

oh & ive sorted out unlocking the voltage & clocks so no worry's there!

Ukkooh I don't know if your trying to call me liar or not, but I have no need too!

I will send you some pics's when my other card gets here @ weekend with benchmarks & all!

I might even do a little build log when im doing my watercooling with copper pipes again?

well just a zalman 9900NT I banged on after dismantling the loop? I didn't even redo thermal paste properly, just used what was on it & set my overclock back to where it was & ive not really checked it properly again until now lol



it was ok under water but are high now! im in the middle of doing upgrades so don't expect me to be that bothered lol?

im not getting any bsod's & im gaming fine, so I didn't bother tbh, it will be ok for a few week's rolleyes.gif

temps are all high @ the mo anyway so until I can afford the gpu blocks,fitting's, piping etc, its staying that way biggrin.gif

Woah that's toasty!

Have you tried disabling hyper threading and seeing the results? I usually have it off, and put it back on when I play BF3 or do something else that's thread intensive.

Less heat, less power, higher clocks thumb.gif

My 980x is @ 4.25ghz with 1.32volts, and the cores don't reach more than 71c in prime 95 for a couple of hours, that's with a noctua nh-d14. I actually don't know if it's a bottleneck for a single 7990, but I wouldn't have thought that a 4.7Ghz i7 wouldn't be enough for two of them?

When you get your gpu waterblocks are you going to put the cpu in the loop as well?

yeah I didn't realize it was running that hot!

like I said im not that bothered, once I get the gpu blocks I can get to sorting it all out & yes the cpu will be in the loop, have to wait till the 15th now for money, im broke lol.

XSPC raystorm, ek xt 360 & ek xt 240, im looking @ the EK alcatel/copper 7990 block's, done in copper piping with aquatuning push fitting's,

Im actually thinking of trying acrylic tubing with those ek HD fittings but cant find enough of the black one's, plus I don't think I can pull it off tbh?

IF a 3770k isn't enough guess ill have to save for a bit & jump to x79 & a 4930k
