My card temperature is at full load max 66-67 degrees at 1220 vcore and 1,25v. Is it safe to try more voltage when the temps are good?
post #16673 of 24913
Its not the core temps that you should be worried about,that temp looks fine....Worry about your vrm,and last time i checked it wasnt advised to run over 1.24 on air....

How is the vrm cooled? Only with water?
post #16675 of 24913
Hey guys!

Edit: Nevermind, it was up to Comodo AV's HIPS protection. rolleyes.gif

I managed to install my 4th 780 so atm I'm trying to save stock bios but I'm having a problem with Ez3Flash:

After choosing #2 nothing happens no matter how long I wait...




I've downloaded it again from the first post just in case there is newer version and from that I get this:




I'm using latest 332.21 drivers. I don't want to flash modded bios until this is sorted because there is a risk that flashing might go wrong.


ps. Saving BIOS with GPU-Z 0.7.5 works fine.




Tomorrow I need to test this beauty...

The reason your getting the error on the second one is because you have another one open somewhere reboot and try again you shouldnt get the nvflash error. Also make sure your removing the protection before flash so it allows it

So i put the skyn3t modded bios and restart. No more throttling that'cool, no more gpu boost too... not a surprised it was annonced.
My card support 1202Mhz/3500Mhz at this moment at 1.15V.
No problem on Fire Strike 9430marks, impressive with a just 4Ghz OC to my 3570K!
And 1941points on unigine 4 extreme

Try to set more voltage but AB don't let me, the option of voltage control was set.

Could also be your OC software, uninstall AB or precisonX, delete their folders, reboot and re install AB or precisionX again!

I will try the sk3net's vbios and make a few bench for try it.
Do you know if it was possible to read the VRM temp on the reference board with AB or GPU-Z?
Warning: Spoiler! (Click to show)
"6 Phase VRM´s (CORE) 60A each = 360A

DC-DC = I(A) × V(V) = P(W) =» 360A x 1.6v = 576W Theoretical MAX Wattage for the core

Plus 2 Phases for the memory and the rest of the card!

@ 1.40v = 504W
@ 1.45v = 522W "

"Did some testings today and this is for all those inquisitive minds out there wandering on the power draw of our beast cards running GK110!

Bear in mind that my system is in my SIG and the only difference was the CPU@4.8Ghz@1,30v! Using triple monitor 3240 x 1920@120hz SLI TITANS W/ Skyn3t Rev2 bios
and memory at stock 6000mhz!

1306mhz / 1,37v / power draw 124% / load 99% 372W*
1333mhz / 1.37v / power draw 134% / load 99% 402W*
1359mhz / 1.37v / power draw 139% / load 99% 417W*
1385mhz / 1.37v / power draw 145% / load 99% 435W*
1400mhz / 1.39v / power draw 155% / load 99% 465W*
*Power draw just for one card
As you can see voltage alone will not increase power draw until you increase clocks and dynamically load your card, power was being drawn from the wall ranging from 850W - 1250W!"

Enough for you? tongue.gif
No, its not possible to read VRM´s temps because there is no sensor on any reference board, you can always use a IR thermometer! thumb.gif

Yes you can! Read our thread here: http://www.overclock.net/t/1425102/updated-ab-b18-team-skyn3ts-unlocked-ncp4206-voltage-llc-mod-tool/0_100 thumb.gif

With stock cooler only the mosfets are cooled but inefficiently, with a waterblock (EK is better) all VRM´s parts that generate heat are covered! thumb.gif

Hey guys - need some help here:

A few months ago, I got my third monitor, and started playing in 5760 x 1200 resolution. When I played Crysis 3 in this resolution, it was super slow (15-15 FPS) with my single GTX 780.
I just purchased and installed another one so now I have 2 x GTX 780 SLI.
Played Crysis 3, and it's even slower! Any idea?
When I play other games, it's better than with a single card. When I do a Valley Benchmark at 1920 x 1200 I get a score of 3843 with 91.8 FPS, min: 30.5 FPS, Max 154 FPS. This tells me that the SLI is working because before I was getting scores in the 1700s.

BTW: no overclocking of anything: memory, CPU or GPUs.

I'm using the latest bios (332.21 WHQL)

My rig:
Asus Rampage IV extreme
i7 3930K
G Skill Trident K 2400 Mhz DDR3 - 4 x 8 Gigs: 32 gig matched set.
Gigabyte GTX780 with EVGA GTX780 in SLI.
Corsair AX860 Platinum PSU
NZXT Switch 810 case.
NZXT Kraken X60 280mm x 140mm water cooling system.
NZXT Hue programmable lighting system
Samsung 840 Pro 256 Gig SSD
Seagate 5,000 rpm 4 TB HDD (data drive)
Seagate USB 3.0 4 TB external hard drive (back-up drive)
LG Blueray burner
Three Samsung SyncMaster 2443BW 1920 x 1200 monitors 60 Hz monitors.
