Testing EVGA's new flagship X79 chipset motherboards E775, E777, and E779 CLASSIFIED 4-way with upcoming classified GTX580 ULTRA cards in the lab right now. Tweaking final bios's at this time on all boards. Nice hardware.:up:
Made some pics and screens to let u guys know whats going over here atm and possibly whats comin. Lets have a look at my fav...E779 classy 4-way




I'm using all 3 3dmark 11 presets and heaven which are the latest and most demanding dx11 benchmarks for performance and stability on current hardware:
Default performance (out of the box with no tweaking or bios adjustment)
Final default card clocks are still being determined on classified ultra, but most likely it should be between 9-950mhz on core frequency:




System memory is 16GB (4x4GB) of DOMINATOR GTX7 and cooling is INTEL watercooler by Asetek. Gskill Phoenix 120GB SSD for hard drive. I'm using 5 CLASSIFIED 1200W PSU's for testing only as I recently modded 4 of them and needed to pretest some stuff. 2 PSU's is actually ok for this system.






Now some sweet spot BCLK/MEM overclocking for this memory config and default cooling. These new CPUS vary A LOT in terms of strength of IMC and OC potential of IMC, so as always CPU is important factor in your individual results. Here I have 16GB of memory running at 2400mhz with rated timings and 129 bclk. This is a nice setting for perf/stability. Cards pushed on air with hottest points in 3d11 test (gt3 peak) marked.





As for Extreme OC on LN2, sandybridge E seems to be better than P67 as most cpus will scale on Ln2, average OC being about 5.2ghz or so. Better CPUS will run below -55c and go 5.4 and higher and bad cpus will have problems -30c and not OC much more than 5.1 or so. I have tested about 20 ES cpus we have laying around the lab so far being a mix of 3930 and 3960's B0,C0, and C1. 3930 is slower than 3960 in 11, and B0 ES cpus are slower than C0 and C1 ES's and cant use bclk ratios along with other limited imc functionality. Hopefully retail 3960x cpus will OC better on LN2 than their ES counterparts similar to the way P67 was. Time will tell.
My overclocking mecca


With easy mod, my CPU containers can fit on our X79 and ANY other motherboards using the INTEL standard cpu socket. No special socket like the one on SR-2 with interchangeable backplate required


That is the best C1 cpu I've found so far out of that 20 (all stepings) in terms of IMC/raw clocks cold. Little better than average but still should make a nice score with the card clocks I have been working on in quad sli.
Got 1300mhz core frequency using my new Tek-9 SLIM 7.0 gpu units on a 4 card test run (all cards are capable of 1500+ 11 clocks on these highly capable SLIM units in single) and it scores a pretty nice 26k using a slow B0 cpu 4.9-5ghz with no memory or base clocks. Classifed ULTRA Core frequency is all that matter on this run:

Looking for 1350mhz+ quad sli on final runs once we find a decent cpu to compete and run all out with, just started testing some other chips now so we'll see. Hardcore huh? NOTHING is as hardcore as the SR-2 was to bench in 4 way. This rig is quite fun and easy to bench as I can actually run it by myself finally. No more LN2 slaves required.
EVBOT is huge this time around. Setting voltages on these cards is insanely easy with our new profile feature for GPU overclocking. 1 click of EVBOT and I can automatically set any voltage on all 4 cards at once before I even get to windows desktop. 1300mhz in quad sli without a single mod on any card
