Hi all,

Looking at picking one of these up (MSI GeForce GTX 670 OC 2048MB) tomorrow as wondered if anybody has one and what are they like?

I am upgrading from a 570 and seems a suitable upgrade.

cheers,

if u mean this http://www.overclockers.co.uk/showproduct.php?prodid=GX-164-MS&groupid=701&catid=1914&subcat=2294

it will prbbly perform like the reference model in terms of temps

you could also get this palit jetstream http://www.overclockers.co.uk/showproduct.php?prodid=GX-012-PL&groupid=701&catid=1914&subcat=2294 that has higher clocks out of box, custom cooler and £10 cheaper
 
Well with the bios modded, 1.21v and 100% fan speed my reference KFA670 is currently at 1270 odd core boost and +375 on memory and is running fine. It ran at just over 13** core when I first flashed it but it throttled quite badly due to heat.

Needs better cooling as the card hits the lower 70s but for the reference card i'm pretty impressed.

Sounds like a jet engine though

You managed to bypass the 1.175 voltage limit :eek:? How and what bios did you used and got any tutorials?
 
ok managed to flash my windforce 3x using gigabyte@bios and mod bios from overclock.net cant believe it is so easy lol :D

went from 1254 (Stock bios)to 1283 core clock. passed 1 unigine bench and still testing if its stable. tried +100 core for 1300 mhz but failed :(

The modded bios puts me over 1300mhz, but I went back to my stock bios.
It's fine to use the modded bios when benching, but for gaming it won't make a difference, and it just increases risk of degradation, or failure.

When a good performance driver is released,I will use modded bios to bench with.
 
Yep followed the directions on here - http://www.overclock.net/t/1289489/gtx-670-unlocked-voltage-bios - was pretty easy actually. Just ran nvflash in bios, backed up my original bios and then flashed the modded reference bios to the card (http://ultrashare.net/hosting/fl/d0114f3f27/REF670_VMOD_BP-200-225_FAN-20-100) as mine is a ref card.

Voltage increased to 1.21v, fan speed at 100% is crazy loud and without touching the clocks default boost is now 12** something compared to 11** something as standard.

Just about to order the 670 water block in order to see how far I can push the card, keep hitting the thermal throttle even with fan at 100% so want to get rid of that. Not expecting amazing results under water but silence would be golden!

What are people's thoughts on KFA2 EX OC vs Gigabyte Windforce? I'm upgrading from a stock GTX 570. I think both are quiet but which has better OC potential?

I think both have two-slot coolers and the only differences seems to be that the KFA2 comes with higher clocks out of the box but the Gigabyte comes with a 3 year warranty (damn ugly blue PCB though!). I would expect to sell it at about the 2 year mark.

Actually the blue pcb isn't as much of an eyesore as I thought it would be. It's a lot darker than the picture suggests.
 
Picked up an MSI GTX 670 OC 2Gb today, first time owning a higher end card - upgraded from a GTS450 :o

Just wanted to check what sort of temps are acceptable at stock speeds (not planning to clock..) , currently under full load stays between 88-90c

Also is it a problem if TDP goes over 100%? Never saw TDP value in the past on my old card :o

Those temps are quite high for a stock card. Hopefully someone like Rusty will offer a more informed opinion than me but I believe some of the 670/680 cards throttle back after they hit 70c. Would be a good idea to keep an eye on your core speeds using afterburner while you are running a heaven bench.

Hmm, GPU clock is showing as 1084.4 MHz , will download Afterburner as I don't have that installed now ...

Fan is only at 67-68%, would have though it'd increase in speed by 70c if that's when throttling starts :confused:
 
If you have it in a cramped case with poor airflow then I would expect high temps with a card that blows the heat back in the case. If this is not the case then those temps do sound high for a 670 with the Twin Frozr cooler on.

Edit.

I'm thinking this is the cheaper 670 with the midget PCB? still temps seem high, maybe a poor HS contact on the GPU.

Well it's not a huge case - Coolermaster 311 if I remember rightly .. airflow shouldn't be too bad, I did tidy the cables more than usual when assembling for once :o

This doesn't have a Twin Frozr cooler , just the one fan on the end

Here's how it is currently - will move some more powerful case fans from other PC and see if that helps, seems has raised overall system temps a fair bit :(
