EVGA GeForce GTX 680 Cracks 1842 MHz Core

Thought the 1800/7700 MHz Radeon HD 7970 OC feat involving an MSI R7970 Lightning was impressive, wait till you see what the punters at EVGA, with K|ngp|n have in store. Armed with NVIDIA GeForce GTX 680 graphics cards, augmented by EVGA EPower board, and PrecisionX software, the EVGA GTX 680 was able to crack the 1800 MHz core frequency mark, reaching 1842 MHz, powered by a core voltage of 1.212V. Interestingly, the memory clock offset wasn't tinkered with. The rest of the system consisted of a Core i7-3960X clocked at ~5.50 GHz. The bench was stable enough to score 14912 points at 3DMark 11 (performance preset). Compare this, to the R7970 Lightning clocked at 1800 MHz core, 7.70 GHz memory (370 GB/s bandwidth), with no additional soldering except plugging in the GPU Reactor, and a slower Core i7-3960X CPU (clocked at 5.00 GHz), which went on to score P15035. Luckily for EVGA, the overclocking feat hasn't ended, and is still work in progress.

W1zzardnobody knows. right now board partners are in panic mode because of all the new thingies and dynamic oc eating into the sales of their OC boards

nvidia was very clear that partners must install power measurement circuitry, must guarantee stability over all clock&voltage combinations, must mention both base and boost clock in their messaging, must enable dynamic oc and can only incresae oc base and boost by the same percentage
Here's to hoping they didn't completey chop our nut's off! :cool:

only thing that is making me scratch my head is why the CPU had to be increased?

Overclocks are nice but id rather have raw power

I love the ghetto soldered add-on board. ...and how much more power did it have to suck down to hit that kind of speed is my question. Does that power efficiency really scale or does the add-on board bypass every little bit of power saving they added to the GPU?

Don't know about the power consumption part but W1zz said the MFG's provided custom BIOSes for OCing/reviewing

I think it was W1zz :confused:

ya and thats the other concern will that lil add-on need cooling?

So your saying these are not the factory bios that will come with the cards/sold? Because I dont think Red Team needed to launch anything such as that as the cards are as is per se.

IIRC They need the custom BIOSes to override the DOC (DynamicOC) otherwise it would remain within it's predetermined paramater's, which is a major hinderance IMHO :o This is most important to people seeking max clock's obviously

Although without DOC i don't think the gtx680 @ 1006Mhz core would have surpassed the 7970, i think they would pretty much be exactly the same performance wise.

I still think they did a good job overall, can't fault them for the improvement's they have made, the "refresh" is what i'm interested to see ;)

Just my $0.02 anyways

Edit: The link to W1zz's post www.techpowerup.com/forums/showpost.php?p=2581156&postcount=20

I believe this is a standard "feature" for all model's

This news is already need update :) We did not slept tonight and kept pushing 680 to new limits. Got 1900MHz running stable, resulting fastest single GPU on planet with P15327 in 3Dmark11 with tesselation enabled as intended by Futuremark :D
Screenie and some photos and details available on KPC homesite

Is it only me, or is there no extra power board soldered to the 7970 unlike this bench here?

I still see soldered wires on the PCB. I would like to know without any hard mods, without any bios flashing, out of the box, what kind of OC will the GTX 680 do? That is what people care about because the average user isn't going to solder new connections to their GPU's PCB and the average user isn't going to have access to the proprietary BIOS for over-clocking either (since all BIOSes now need to be digitally signed, bye bye bios modding).

Edit: This is also using LN2. Give me some 24/7 over-clocks please.

Just tried this out. Realized it's literally just afterburner with a less convenient UI. No thanks.

Hilbert got ~1300mhz with a reference 680 with the fan at stock speed, using MSI afterburner.
