Nice, glad to see someone else backing up my tests. Although the difference isn't as dramatic as mine due to a lower resolutions and card count, they are still very impressive differences. :thumb:

I'm running a 19" LCD and can barely make out that chart, is there perhaps a link you could provide? Also what do the different colors represent? Thanks Callsign_Vega for all of your valuable work you have done for this community!Quote:

The forum probably re-sized it, but yeah it's bigger once you save it to your pictures. It shows the resolution and settings used, but what do the different colors mean? Min, Avg, Max?Quote:

I guess Google Chrome doesn't allow anything, it's a dead picture, no problem I downloaded it and can see it fine.Quote:

You can see at single monitor it doesn't make a big difference but it sure does at multi-monitor as I've always said.
I NEED TO KNOW....Quote:

i just noticed bf3 has low utilization on my card... around 70%
if i get a 3770k with pciexpress 3.0 can i increase gpu utilization?
Yes 8x 2.0 is garbage :)
I forgot how much work it is to get these large water setups done properly. :thumb:
Assembly line done.

X79 chip-set, RAM and MOSFET/VRM blocks installed.

Setting up GPU's.

One of the GPU's temperature is a lot higher than the other three. It is quite strange as I assembled all blocks exactly the same, with the same TIM and quantity. So far the good ones are idling at 25-27C and under load around high 30's C. Not looking forward to draining and re-doing card #2. Hopefully I don't have a bad block. :mad:
how much higher is it?
could be air bubbles stuck in there
It was a stand-off that wasn't fully seated from factory. Corrected and now all GPU's idle 21-25 C and full overclock load 33-38 C. All button up and ready to roar:Quote:

I've had success getting a custom resolution and frequency working in Surround! Running 3600x1877 @ 95Hz. That corrects for a perfect GW900 aspect ratio for each screen, increases the Hz a nice bit above stock settings and the whole display setup us almost a 2:1 width/height ratio which is just about perfect.
I am running these settings right now and they seem to be doing pretty well:
3960X @ 5 GHz @ 1.47v.
105 MHz Base-clock for a little more PCI-E "oomph".
2240 MHz @ 9-11-11-28 on the 16GB RAM. May try and get those timing a bit lower in the future.
Idle @ 28 C and game load 45-55 C. Prime95 full load temps are ~57 C. I also purchased the Intel overclock warranty for $35, small price I think for some piece of mind and they cross ship if you let them put a reserve amount on your credit card.
Nice numbers update, Vega! Thank you.
Now, time for some more videos, please? :D
On my 4-way GTX 680 setup using EVGA reference cards with EK water blocks, my stable overclock is 1202 MHz core and 3534 MHz memory. Pretty much spent all day testing those clocks using Heaven 3.0, BF3, Crysis 2, Metro 2033 and Skyrim with some mods and HD texture pack would crash at the lowest frequency. So modded Skyrim set my ceiling. I found though that performance scales linearly with increased memory clocks and there is no "sweet spot". Get that memory frequency as high as it can go!Quote:

I am just astounded by how smooth the GTX 680 handles Surround using PCI-E 3.0 slots. There is no micro-stuttering, pauses or jitters. I don't think I could tell the difference between a single GPU running a single monitor and this 4-Way SLI Surround setup. Combine that with the CRT's and this is by far the smoothest and best Surround/Eyefinity setup of mine to date. ;)
It will be interesting to see if any of these new EVGA non-reference cards will allow the voltage to rise above software 1.175 (I think really the only way to get more clocks out of these and just not more power phases).
The great news is that with driver 301.25 I no longer have the Surround setup not working on cold boot-up problem. Everything is working great now in Surround mode.
I've noticed that Witcher 2 has a problem when I load up the game, instead of it filling the screen, it's just a narrow landscape type view into the world. Anyone familiar with Surround/Eyefinity in Witcher 2 know how to fix that?
Can you show us what general-purpose PC usage looks like on that type of setup? Web browsing, the Windows desktop, f00bar, GiMP, Steam, etc, etc?
If these guys at WSGF cant fix it then its an inherent problem with the game. It works in landscape but not portrait.... sorry! http://widescreengamingforum.com/for...er-box?page=44Quote:

I plan to upgrade to 2 or 3 GTX 680s later on and was wondering about this PCIe 3.0 bottleneck thing. I've currently got 3 screens in surround at 5760 x 1200, would Z77 be a bottleneck for this if I used 2 cards with PCIe 3.0 x8 x8? How about the Z77 MBs with the PLX chip that can do PCIe 3.0 3way SLI at x16 x8 x8?
Is this PCIe bottleneck thing mainly for 3 - 4 cards or does it affect even 2 cards in Surround resolutions?
Two cards I would get Z77. Three cards I would get X79.
