Graphics My Watercooled QUAD SLI GTX 670 4GB Cards Powered with 2 PSU's **Benchmarks PG10**

Mate that'd be great!

Would you be able to set the throttling to kick in at 90C? I don't mind them running hot - not that they will with the cooler they have anyway.

 

There is no way to set the throttling temp unfortunately, only GTX Titan allow that in software.

VBIOS parameters set to - Default boost. 3500MHz (7000MHz) Memory. Power Limit 145%. Voltage 1212.5mV.

Your card should boost to 1267MHz core.

Vbios 660TI

NVFlash Download

Download nvflash - and put the 2 files (Minus the Doc) on a DOS bootable USB Stick.

Now download the Vbios and add that to the USB stick. And finally add the Original vbios, and leave that named as GK104 (4 Files total including the vbios!)

Now reboot, and load into DOS. Now type;

nvflash -i2 660.rom

(Make sure to keep spaces in between like shown!)

Press enter, then press Y. Once the process has been successful. ALT TAB DEL to reboot.

Now test the 3rd card, either in Tri SLI or on it's own. If stable, and boosting to the max. (May have to enable Prefer max performance in NV CP or set the max power limit in afterburner to max. But test without changing these first.)

Your GPU's will be 0, 1, 2 - You will be flashing GPU 3 with -i2. GPU 2 with -i1 and GPU 1 with -i0

If you need to flash back to the original then type this in DOS;

nvflash -i2 GK104.rom

Or changing -i2 for -i0 or -i1 for which GPU you are flashing.

BTW - I'm still pulling my hair out, trying to get this working. I have flashed all the cards to use the same vbios, with no luck, tested my F.T.W cards in tri SLI = No problems. Ran every card individually = No problems. (That PCI-E power switch is a god send for turning off each PCI-E lane when needed to test!)

 

I think the problem is a broken 4 way SLI Bridge - as I keep getting the ballon pop up about connecting it, but yet in Nvidia control panel, it's showing 4 way SLI...

 

Things like that are freaking annoying... but at least it'll be a simple fix! No having to remove a card from your wc setup or anything like that. That sort of thing pisses me off! (not that it's hard, just the effort and the time spent)

 

Spent most of today trying everything to get this running. Turns out the SLI Bridge is fine.
So now going to sell the SC card and look at getting a F.T.W card to replace it.

 

called F.T.W. for a reason then...

 

Too bad your in the UK I would love to take the 670 off of your hands, as I am currently trying to earn the money to get one, but i'm afraid the taxes and fees shipping overseas would make it not worth it. I hope you get the issue sorted. Did you try it in 3 way SLI and using the 4th card for Physx? I'm just curious how that effects your performance.

 

Just installed windows 8, and I have now got the piece of .... Working!

 

Congratz now lets see some Benchies!

 

I will later, as I have now got to install everything, and also get used to this ass about face OS.

 

True_gamer must be trying to set a new world record for "highest number of GPUs bought and sold in a month"

Can't wait until you have 4 670 f.t.w.s benched!

 

Unlucky

Nice work, await benchies

 

Thanks for the bios! I'm at the folks for Easter so will try it next week.

Ugh, Windows 8.

Still, looking forward to your benches!

 

Rumour has it that performance is better though... Ever so slightly.

 

Urgh. Metro.

 

I know, I know - I'm trying to get used to it. I do prefer Windows 7. I'll try and get a Heaven benchmark up a little later. Still got a lot of installs and downloading to do...

 

Id sacrifice a 4th card to avoid metro!

I doff my hat to putting up with such things in the name of benching.

 

start8 allows you to use windows 8 the way you want.

So was it just switching to windows 8. that fixed the problems. Are you still going for a fourth f.t.w or are you taking an upgrade breather now the four cards are working.

 

Tri SLI 1306MHz core 7114MHz memory

Heaven 2.5




F.T.W cards all running 1306MHz core - 7406MHz memory
SC card running 1254MHz core - 7406MHz memory. (Max OC the card will do!)

Heaven 2.5

 

Nope. Lost all hope for that when first wind of the TITAN supercomputer.

University student crawling throught the servers checking to make sure all is well after a night of oc'ing a million dollar machine and playing crysis:
"GODAMMIT! NOW WHICH ONE is burning?!"

Nice bench.
