***Official GTX 670 thread***

Well its only -25 Mhz at 80 degrees, but this means worse benchmark scores. The GPU boost can somehow be disabled, and the GPU clock locked using Nbitor, which I will try out tomorrow.

GPU boost completely ruins GK104 IMO.

Boxing my card up, DSR'ing it, my 570 ran fine, was a lot quieter, no stuttering, and it's core clock stayed locked at even 90c.

With regards to DSR, do I have to have a reasonable excuse to why I don't want it? I can use the card for a week and decide that it doesn't suit my needs or I don't find it to be the card I expect you can return it on that basis?

I though using the product prevented you returning something on DSR, I mean that means they'd have a bunch of cards that have been returned and already used stopping them from reseale as new right?

You have to be able to at least test the product to know whether it's to your liking, your reasonable excuse is that the product doesn't suit your requirements, the truth basically.

They will sell the cards as b-grade most probably.

Thanks, Well I guess I'll have a think about it. The card is great in terms of game performance don't get me wrong but seeing as I had used an AMD card for the last few years I'm used to the card doing what I ask of it when I change the clock settings and this boost clock really winds me up. I'm buying a high end gaming card because I don't care about energy consumption, if I cared I would go for a lower model so I don't see why it keeps throttling itself or changing the clock to conserve power.
 
The throttling and GPU boost can be disabled with Nbitor, but I wont be able to try this until tomorrow. If the method works and allows the GPU clock to be locked, I will make a thread on how to do this.

What do you guys think of this third party vga cooler http://www.arctic.ac/en/p/cooling/vga/375/accelero-twin-turbo-ii.html?c=2182

It's says it's compatible with the 670, it can be had for around £32

Will this work on a smaller PCB?

Looks identical in almost every way to the KFA2 EX OC cooler, which wan only £35 more than the reference design in the first place.

This is why customs editions are worth it, for the same cost as that cooler, you not only get a near identical cooler, but also the bigger PCB, more power pins, and a much higher guaranteed stock clock.

Yeah, for $180 it should come with a legal guarantee that they'll freely ship you a kit to fit it on the equivalent next gen card...and the one after that! :p

That's really good then, just keep the fan on 60% which is silent on mine.

At 60% fan speed I was still getting 71 degrees, and reduced from 1215 to 1202 at stock settings which nearly made want to have the card swapped to a gigabyte, but I managed to fix it :)

You were going to swap a video card because it lost 13 MHz clock speed when it went over 70 degrees? When it takes 100's of MHz to give you a couple of frames in a benchmark.

Seriously, words fail me.
 
Bhavv, more on this nibitor clock locking? As I can't get anything 670 wise to read in nibitor.

Add me to steam too if you want, id is same as my user name here.

As for the MSI overvoltage cards, seems a little pointless, one of these two reasons will explain its existence.

1. The cards come under-volted at stock clocks, "over-volting" still caps out at 1.175v, which is standard over 6x0.

2. The card has a higher upper voltage limit (by how much?) and is aimed at non-air cooling.

Why MSI haven't announced a 680 PCB based twin frozr with this 'higher voltage' is beyond me. They can do what they like with the voltages that ref cooler isn't going to cut it at higher clocks, well unless they set the boost cut thermal limit to +80c anyway.

Erm no. An ooverclock of just 42 Mhz on the GPU and 850 on the ram gives an extra 6 FPS in Crysis 2:

Every little bit helps with GPU overclocking. Look through all the reviews of the Gigabyte card's overclocked performance, every 10 Mhz on these cards brings an improvement.

I was thinking of changing it for a Gigabyte Windforce becaude I was getting over 70 degrees at 1250 Mhz, while the Windforce runs at 60 degrees at the same clock without even touching the fan speeds. But I fixed that with a cooler reseat.

I dont believe that any graphics card should be being throttled at all when running at stock settings, if I get a card thats comfortably running at 1215 Mhz out of the box, I want it running at 1215 Mhz in all my games and benchmarks.

I dont really know tbh, I'm not going to bother trying to force or change the clocks in any third party app now, I'm ok with this:

66% fan speed keeps my temperature below 70 degrees now, and that was after two looped Heaven runs. The Windforce cooler is still quite a bit better, but my card is running fine now. However plenty of other people with this KFA2 card are going to be hitting 70 degrees on stock clocks.

Galaxy/KFA are the same brand right?

I just don't understand the reason why this boost clock means whatever settings I want it at my card just completely ignores anyway. I'm use to the card simply following my orders all the time (AMD) and this is just a whole new world where the card refuses.

I can get my card up to 1250 if I put the fan on 75% other it will throttle itself as soon as it touches 70 degrees, which to me is just plain stupid.

I have KFA2 EX OC and mine do 1359 MHz 3dmark 11 stable with score 10390 mate.
