***Official GTX 670 thread***

[ed79]

I'm working on a list of games at the moment, so far Fifa12, Batman AC and Dirt 3 seem to have the issue. The only real trend I'm noticing is the power consumption drops at the same time as the frame drop that causes the stutter. I've also noticed that the voltage is lower if you play a less demanding title while overclocked, for example, fifa12 at stock sets at 1.09v, overclocked it sets at 0.97v, though the stutter appears with both settings.

If you google about stutter on the 680 it will yield more results as there are more 680 owners.

IMO the sooner someone finds how to set a static 3D clock the better. The 'boost' at the moment seems more hassle than its worth.

I'm not bias to any side, I always choose what offers the best performance at the best price.

Please add GTR Evo to the list of stuttering games. Seems it's older, less demanding games that the card decides to downclock for whatever reason. vsync on or off made no difference.

Have posted the following the the "Nvidia Stuttering" thread...

Interesting, from last week, didn't know EVGA recalled 670's???

yep, bunch of faulty superclocked cards. evga gave everyone who purchased one a free upgrade to the ftw edition of the 670.

The nvidia brigade are usually quite quiet when there is something going against their brand. Stuttering? Lets just brush that under the carpet and show you some more benchmarks...

Just wanted to share something with the rest of the windforce owners. I ve flashed my gtx 670 using an Asus Bios to unlock the power limit to a bigger percentage. I ve noticed that with the Gigabyte bios temperatures go up to 66 degrees and with the Asus bios temperatures would cap at 61 degrees using the exact fan profile and the exact same clock/memory frequency. The maximum overclock i can get with the gigabyte bios (on the gpu clock) was less than the stock settings of the Asus bios so i had to drop the frequency just a bit to compare the two. Does this imply that there is room for improvement on behalf of gigabyte releasing a better bios?
I also found that using the gigabyte bios my heaven score is about 2068 and for the asus bios the score is about 2017 even though they had exactly the same speeds. With the asus bios i could achieve slightly higher clocks compared to the giga one and better speed boost( 1293 vs 1267 ) however as you can see from the Heaven score it didnt translate to better performance, it was actually slightly lower) Overclocking with the Asus bios to even higher clocks Heaven was "stable" with the gpu reporting over 1300 boost however the performance would be much worse ( 1754 heaven score)
I ll post some images when i find the time as am still taking exams and am drowning myself with maths, 3 exams in a row, Monday,Tuesday,Wednesday)

I can't get my bios to backup. lol
haven't done this in a while.

Can't you back it up from GPU-Z?

 

[Varashtr]

Does everyone experience stuttering or is it just a select few?

Has anyone figured out a (temporary) fix?

Thanks.

download nvflash from http://www.softpedia.com/get/Tweak/Video-Tweak/nVFlash.shtml

extract it in your desktop, open command prompt by typing cmd in the search-box when you click on the window start icon

Type "cd Desktop" and press enter
then type "nvflash --save windforce.rom"

you can use another filename if you prefer

double post arggggg, there was something wrong with the connection

 

[Xp0c]

Got it! Thanks

I got the Galaxy dual fan, and may flash to windforce.

Also to prove my earlier speculation on Memory vs Core clocking, check out these results...Heaven, OcUK 1080 standard.

Core boost clock of 1300mhz, memory at stock, power +111%

Score: 1875
FPS:74.4


Core boost stock of 1189mhz, memory at 7200mhz effective (+600), power +111%

Score: 1882
FPS: 74.7

I'm going to retest them just shortly as I have a hunch that Adaptive V-sync is enabled which may harm the scores.

Edit: nope, A-V-Sync was already disabled.

Default mem clock is 6000 effective yes?

Also what Score do you get with no changes to either?

Looked at the gigabyte 670 and its up to £300 ext vat Its more expensive than the cheapest 7970. Don't know why they do this as the 7970 is a faster card. I really want to buy nv this around after having a 4890 and 5870. I miss the custom profiles for games. Yes amd have this too but its not user friendly as the nv one.

Or you can use the nvflash backup option, its all the same thing.

I'd stay aways from other stock BIOS files for now, I got artefacting at stock with a zotac BIOS, remember the wf is the only 680 ref PCB 5 phase board atm.

The Inno3D iChiLL GTX 670 also has 5 phase pcb, as well as a blue pcb.

 

[pgi947]

I haven't seen that card, seriously considering sending the card back atm, my 14 day grace period with ocuk is up on Thursday, need to pay off a holiday and then save for something a little more tweakable.

Here's my impressions of the gainward reference 670.

Box was very light, thought I had been sent an empty box at first but luckily the card was in there

Barley any accessories, 1 dvi to vga, 1 molex to 6 pin, driver cd + quick start guide.

Right after powering on the switch the fan made a loud buzz noise which quietened almost instantly. However the fan does still definitely buzz like others have said but it doesn't bother me at all.

Idle temperature is 27-33 depending if the card is downclocked or not. (Literally just checked gpu-z as writing this sentence and temperature is now 25)

Running heaven max temp was 77 and fan speed was 45 percent I think (max speed possible is 80 percent). Doesn't sound much louder than idle but once you get to 50 things start getting loud.

Power consumption during heaven was 220w compared to 350 of a single 570, 550 of 570sli and 300 of a single 560ti.

Heaven @ stock speeds was 68 fps. Using msi afterburner I put +100 on the core and +200 on the memory without touching the voltage and was perfectly stable. Boost was 1185

The 670 is faster than the 7970, prices are high atm becausce Nvidia can't supply enough cards to meet demand, what stock there is therefore gets priced higher. In a few weeks/months prices will be much better on both camps. Why not wait a while?
