ASUS GeForce GTX 680 Direct CU II 2 GB - Voltage control!

This card will only cost $520 and will feature a cool and quiet 3 slot cooler and voltage control past stock limitations as well as healthy enhancements to the quality and number of power phases. I want one!

Impressive.

[FONT=verdana,geneva]The memory on this board is flying frickin fast ! We got it running stable at 3600 MHz, which is a 7200 MHz effective gDDR5 datarate.
So for the core we ended at roughly 1367 MHz (!) with the dynamic clock kicking in, absolutely stable and for the memory we ended at 7200 MHz (effective data rate). The cooler was laft alone for fan RPM and it remained quite inaudible. It kept the GPU under 75 Degrees C when overclocked. With that extra performance at our hands, have a peek at the results when overclocked.
Oh and please DO compare the reference GTX 680 performance to the overclocked performance.

Above, Crysis 2, same maxed out image quality settings as before yet now with added overclock results:​

This is what the GTX 680 was supposed to be, never should have released their 'flagship' card with such crippled stock oc potential.

0.99 - 1.175 V

Am I missing something?

 

[blackened23]

I dont' believe it has voltage control. It does have more available TDP since it uses 8+6 pin for power, hence the power limit is increased to 150%.

Lol it doesn't have voltage control. That's why TPU and Guru3D don't mention it. Its just easier to Vmod for more voltage.

Option 1: wire the voltage control points into your ROG motherboard voltage control headers.
Option 2: wire your own variable resistors into voltage control points.

Both void your warranty. Even with increased TDP limit, voltage is still hardlocked to 1.175V.

I'm still interested in this card though, this and the Zotac Extreme.

 

[blackened23]

Yeah, I really don't see myself hardmodding a card for tweaking the voltage. I also wouldn't buy a maximus ROG board (which is a prerequisite), although I am an asus motherboard fanboy (just got my P8z77 deluxe) The good news is that it has an increased power limit range so that should help the max GPU boost.

 

[BallaTheFeared]

Both void your warranty. Even with increased TDP limit, voltage is still hardlocked to 1.175V.

You will have to remove the resistor marked PGR100 to remove the 1.175v Vcore overvoltage protection.

Just know what you're doing

 

[Grooveriding]

No voltage control. Just a cherry picked card sent for review with a nice cooler.

Even the EVGA 680 HC+ custom water card is the same deal. 8+6pin, no voltage control, whooppee for extra TDP you cannot use.

The volt mod can be done on any 680 if you own a ROG board, but really ? LOL the future of over-volting is the past, soldering wires and make sure you own a $500 motherboard. :biggrin:

 

[chimaxi83]

You really don't even need a ROG board, that dude TiN posted up a guide on doing it yourself, lol for "average" users with a little skill.

Either way, controlling voltage shouldn't have to be done these days by hard modding your card, especially for top of the line. Once you get into realm of LN2 and extreme benching, hard mod all you want. But to maximize on water/air, we should be able to do it ourselves. 7900 has it, why not 680?

TPU got max boost to 1275MHz, Guru3D to 1367MHz, and VR-Zone to 1328MHz with no Vmod. They didn't do a Vmodded overclock, but it looks like near 1300MHz is possible with this card.... and my card maxes at 1275MHz. Nothing special, imo.

 

[Tempered81]

Impressive.

 

[chimaxi83]

lol, oc performance within what, less than 2% or so.

 

[blackened23]

What speed was the DC2 7970 oc at?

 

[OILFIELDTRASH]

This is the worst gen of cards to date since I started pc gaming. Between rising msrp on AMD's side, voltage locked gtx 680, low availability of 28nm, etc..
I'm going to either pay $500 for an upgrade or wait till next gen to replace a gtx 480.
Needless to say I'm waiting.

 

[Tempered81]

lol, oc performance within what, less than 2% or so.

Max overclock at the highest resolution, the 7970 is about 4% faster

 

[chimaxi83]

A vote of confidence from VR-Zone on attainable clock speeds with the voltage mod:

coming up in a separate article. wanted to complete the tests first before potentially bricking the card

As long as nothing goes wrong though, 1400-1500+ should be pretty easy with voltage control

 

[utahraptor]

All you have to do is bridge a single point to allow the software to exceed the stock voltage limitation.

Edit: I may be wrong about the software being able to adjust the voltage after the mod >.<

 

[blackened23]

I would be all over this if it were not triple slot. Thats why MSI lightning remains my favorite air cooled enthusiast card...it does everything the DC2 does minus 1 slot space.

Got mine today from Newegg. Out of the box I ran some benches without any additional OC.

3DMark 11 Basic stretched

3DMark Score P9083
Graphics Score 10520
Physics Score 6470
Combined Score 6404

Heaven using the OCN top 30 settings

FPS: 53.3
Scores: 1343
Min FPS: 26.0
Max FPS: 147.2

I set the fan profile to raise 1% for every 1C and it maxed out at 60C with 3DMark 11 and 56C with Heaven.

 

[chimaxi83]

Nice! Got mine too, couldn't snag a TOP version though. I'll be posting up some kind of bench/score/overclocking adventure soon

 

[Don Karnage]

Mine shipped today. Hoping it'll be here Saturday. Can't wait to get her on water

 

[chimaxi83]

Hit 1325 in SLI right outta the box, too bad my other card maxes at 1265 :sneaky: lol

are they both Direct CU cards? and what are you hitting for the memory?
