Sorry I was talking about the OC results of the 5775c in the first link. At stock, the 5775c is at a huge disadvantage with about 800mhz less clock speeds, but the 7700k only beats the 5775c by 1 or 2 fps on average. At OC speeds the 5775c beats the 7700k handily, even with 800mhz less speeds. Clock for clock, the 5775c clearly beats the 7700k on almost every game, except Crysis 3.
The second link has a 6700k. We can draw estimates for the 7700k too since both CPUs perform equally clock for clock.

Anyway, what I really want to say is just that benchmarks are just hard to trust these days. Looking at pcgameshardware's test, the 7700k beats the 5775c at StarCraft 2 by a HUGE margin, but in purepc's test, the 5775c beats the 6700k/7700k at StarCraft 2.

Also, how could it be simply due to better cooling fans? I didn't understand that part.

Rumor has it that these gpu's will be voltage locked. If that's the case I'm just assuming the additional power added from 2x8pin on select AIB's is for the additional fans/ RGB's etc over what the FE has.

Voltage-locked as in even the Afterburner voltage slider won't work? I was assuming all Pascal cards are voltage-locked.

You will run into a CPU bottleneck. 2 cards are too fast, at least for my 4930k 6 core @ 4.5ghz at 1440p. It's not until I use DSR to downsample from 4k or higher do I get full 98%-99% usage rate on both cards. This happens in 3Dmark Firestrike as well btw (the standard test).

It's happened on Mass Effect Andromeda, Battlefield 1, GTA V, Rise of the Tomb Raider, 3DMARK. So it's not just a one off thing. Single GPU this isn't an issue.
I'm curious as to how you're running into a CPU bottleneck, is one of the cores running at 100% or is the CPU utilisation completely maxing out? I've not run into any such issues with 1080 Ti SLI with a 6800K 6 core, pushing 98-99% usage handily in most games at 4K. Crisis 3 even pushed both cards to 100% each.

Have you tried running at 1440p? Because at 1440p those Tis get a lot stronger at bottlenecking CPUs...

Myself and others have found the unlocked voltage slider does not increase max voltages but DOES on water keep voltages at the maximum 1.062v without it dropping lower more constantly.

With it in an earlier post without shunt mod doing a Heaven run my voltages stayed at 1.062 99% of the run, I think the few seconds dip was a Power Limit issue.

Without it voltages and clocks dipped much more off and on.

I hate you... rolleyes.giftongue.gif

Would you mind running without SLI and letting my know what kinda results you get in both? I'm curious to know how both play at that res.
yep. that's the best buy in 1440p 144hz g-sync right there

These guys had the 5775c in their test. 7700k won 5 of 7 vs it including minimums.
@ 3.3 GHZ. it's magic but it can't overcome 1.7 ghz. try it again @ 4.3

Here, the 5775c handily beats the 7700k in most of the tests both at stock and OC speeds, with the 7700k having a 500-800mhz clock lead over the 5775c

Another one:
https://www.purepc.pl/pamieci_ram/test_ddr3_vs_ddr4_jakie_pamieci_ram_wybrac_do_intel_skylake?page=0,18
The only game where the 7700k beats the 5775c is Crysis 3.
THANK YOU> I finally got some back-up!! Appreciate it, man.

everytime i bring it up i get abused by the forum. So many IGNORANT posters on here it's pathetic. I thought on Ooverclock.net we'd have smarter posters....
