These game numbers are just based on my max game stable overclocks from Precision-X, stock LN2 bios at +75 volts since I don't want to use the Classified Tool for 24/7 usage so the clocks are 1320 core/1725 memory. These are pretty high even compared to reference overclocked 780 Ti cards in SLI so I am pretty happy here, but that poor, poor memory is not going to win me any benchmarks.

1) Bioshock Infinite: 1080p, ultra- 189 fps average
2) Bioshock Infinite: 1440p, ultra- 157.5 fps average
3) Star Swarm on Dx3d: 47.6 fps average (No SLI on this yet, and I personally they have purposely gimped performance on Nvidia cards)
4) Batman: Arkham Origins: 1080p, highest settings possible everywhere other than with no PhysX to make it fair for AMD users- 347 fps average
5) Batman: Arkham Origins: 1440p, highest settings possible everywhere other than with no PhysX to make it fair for AMD users- 269 fps average
6) Saints Row 4: 1080p, ultra- 195 fps average
7) Saints Row 4: 1440p, ultra- 137 fps average
8) Far Cry 3: 1440p, ultra- 118 fps average
9) Tomb Raider: 1080p, ultra - 305.7 fps average
10) Tomb Raider: 1440p, ultra - 203.8 fps average
 
Ya, I forgot to mention those were on the latest beta driver so comparing to benchmarks from 2 months ago isn't really fair. So if anyone has latest reference SLI numbers to compare, it would be great.

My cards can get upto 1452 core at 1.212 V stable in valley but that doesn't mean much for gaming, does it? :rolleyes:
 
TBH those are easily 24/7 volts on water so 1452 core if actually game stable is immense!. Max I can get mine to run in Tri or dual config is 1250/1925 and that's probably not game stable. (EVGA SC ref cards)
 
I am on 1.212 V 24/7 anyway, but 1452 is too much for some games- especially in SLI. So I tuned it down to 1250 to be safe. Now and again it still crashes but I think it is more to do with the beta driver I am using than anything else. Unless 3 gigs of VRAM ain't enough, I should be good to go for a long while with this setup- until I get the upgrade bug that is!!

Some core voltage data off my DMM for my KPE #1 at stock clocks on the stock LN2 bios with no dip switch on:

A. Zero load, 260 KHz PWM frequency

Stock volts: 0.9
1 V via classy tool: 1.013
1.1 V via classy tool: 1.1145
1.2 V via classy tool: 1.218
1.3 V via classy tool: 1.317
1.4 V via classy tool: 1.422
1.45 V via classy tool: 1.475
1.5 V via classy tool: 1.523

B. While running Valley, 260 KHz PWM frequency

Stock volts/1.175 V read on classy tool automatically: 1.217
1.25 V via classy tool: 1.293
1.3 V via classy tool: 1.341
1.35 V via classy tool: 1.394
1.4 V via classy tool: 1.439
1.45 V via classy tool: 1.485
1.5 V via classy tool: 1.532


C. Zero load, 400 KHz PWM frequency

Stock volts: 0.9
1 V via classy tool: 1.013
1.1 V via classy tool: 1.115
1.2 V via classy tool: 1.219
1.3 V via classy tool: 1.321
1.4 V via classy tool: 1.4285
1.45 V via classy tool: 1.483
1.5 V via classy tool: 1.5375

D. While running Valley, 400 KHz PWM frequency

1.4 V via classy tool: 1.4625
1.45 V via classy tool: 1.512
1.5 V via classy tool: 1.563


E. While running Valley, 457 KHz PWM frequency

Stock volts/1.175 V read on classy tool automatically: 1.235
1.25 V via classy tool: 1.306
1.3 V via classy tool: 1.367
1.35 V via classy tool: 1.4155
1.4 V via classy tool: 1.463
1.45 V via classy tool: 1.514
1.5 V via classy tool: 1.5645

I didn't notice a whole lot of change after increasing the PWM frequency past 457 KHz, also this confirms the new Classy tool works with pretty much all the bios out there.

Why you running such crazy volts on water man?? Those are LN2 volts!!!
Click to expand...

Perhaps you could help me here- what dictates the max volts for air, water, LN2 etc? My temps are not bad- get a max of 45 C at 1.4 V and about 50-55 C max at 1.5V. Of course I don't plan on running 1.5V no more than I have to but wanted to know what is the danger point. I figured the GPU itself is the weakest point at high volts since the PCB can handle 1.5V easy.
 
Really surprised they have not received any stock yet, EVGA US&EU had it in stock on multiple occasions. Hopefully you guys on pre-order will get them soon and it won't end up like the Asus black edition mobo.

Had a little play with mine on air with stock voltage. The memory on mine seems to clock really well compared to others I've seen. She will do -

Stock bios
1333 MHz core (not tried higher yet)
7900 MHz memory and 8000 MHz with very slight artifacts
Max temp was 65c

3888 bios with less aggressive memory timing.
Same core so far but I don't think it will go much higher with stock voltage tbh.
Memory was a touch better at 8100 MHz, this will go higher however.

I might go back to the original bios and tighter timings with my memory clocking well?
I'll slap on a DMM tomorrow and see what it will do on air before it all goes under water.

The improved ACX cooler does a really good job, the fans on full steam really push some air.

I too would like to know this, for me there are no worthwhile gains above 1.425v but i have tried a couple of runs at 1.5v and my max temp was 49c whilst running the valley benchmark.

One of mine does 8300mhz on XOC bios (tight) and holds it with core up. FBVDD=sub 1.8v. The other just scrapes 7600mhz and doesn't like much of an increase in volts. (run's 1.72v stock)

High clock mem card does 1425mhz core (doesn't scale well, not on ambient anyway), low clock mem card does 1477mhz core for same volts (will keep going with voltage), both score the same on 3DM, gives you an idea of comparable difference between core & mem.

VDDC max was 1.5v (DMM) when testing both cards, temps around 30deg for core and vrms. (560mm push pull dedicated to single gpu with 15deg ambient, Delta on vrms)

Just like cpu it's not all about the temps! I could run my haswell's/IVE's up above 1.5v and still retain good temp on water but it would kill the chips rather quickly!

Berno - yep some of us pre-ordered on 20th December and it's a shame that evga seem happy to knock the cards out to Joe public via their store rather than to us, even if it was only a small batch. We are also paying 20% more than the evga store price so we are last and pay the most.

I would cancel my order but I already invested in blocks and backplates.

I would have at least sent 8pack a card considering the records he has been breaking lately.

I've just got the "560mm bit" :eek: ......120mm on the end of my GPUs :)

Max for me under SLI is 7300 on the mem, that's various bioses as well....:rolleyes:

Gnaah!......I'm not jealous.....really.......I'm not......honestly.......... :cool:

I might be putting too much volts into them Samsung thingies with the EVbot so...........
