***Official GTX 670 thread***

[bhavv]

it's proof of nothing, evga are blaming the memory for the problems, which is only rated to 6ghz but they pre oc to 6.2

reviews are quoting the evga sc as stable at 1280 boost but the few cards that have the problem have it out of the box with no oc possible, it's dodgy quality control, not a pcb problem

Do they use the same hynix memory that everone else is clocking to over 7000 MHz? Everyones GTX 670 has ram rated for 6000 Mhz, its still overclocking to at least 6800 Mhz on every non EVGA card.

And reviews use cherry picked cards, with the number of failing EVGA SC cards, it shows that there is clearly something wrong when you take the reference design and mass produce it just slightly overclocked.

Everysingle KFA2 EX OC is working at 1215 Mhz out of the box. Probably fewer than 50% of reference designs will even reach 1150 Mhz.

The reference design GTX 670 is a fail, as the EVGA SC version shows. If its not the PCBs fault then why are they replacing them with full length FTW versions?

Snap, 1.2v would be a godsend.

This.

111% / 150% power target wont mean anything if my card only goes up to 75% power usage

i have a EVGA SC 670 and mine is fine and oc's as high as quite a few non ref 670's i get 1296 boost with 7Ghz on the memory np

customer service?
msi cards are OC'd the same and there's no reports of them having problems out of the box, it is clearly an EVGA QC problem, not a PCB design issue
every review of a short PCB I've seen (and user review) is saying low 1200's as a minimum when OC'd

Well i must just be an unlucky one then :/

You're the first I've read about, but mine should be here tomorrow so I'll let you know :/

The reference 670's are indeed a cheap cut around for Nvidia.

Allot of Referance 670's are having problems overclocking if you look on the Nvidia forums, and also heat/noise when they are because of their unnecessary cooler which looks as if it should be on a £100 card, not a £300+ card with a large shroud to hide it.

Review samples were also no doubt cherry picked.

Do you understand what the term 'cherry picked' means? Manufacturers send their absolute best clocking cards to be reviewed, what you normally see in reviews that are based on manufacturer provided cards is at best what 1% of those cards will reach.

Please show me where all the actual people that bought reference designs and are getting 1200+ Mhz stable clocks are. Also do make sure that those overclocks are staying below the thermal throttle at 70 degrees to be valid.

People on the EVGA forum are blaming the reference PCB. So are EVGA indirectly by replacing these cards with full length PCB versions instead. No one with even the most basic understanding of overclocking likes the GTX 670 reference design, it only exists for people who are ok with running it at stock speeds.

 

[RavenXXX2]

Reference 670 PCB is real cheap, with the bolted on full length cooler it looks even cheaper, how they can charge £300+ for it is beyond me.

 

[psychodil]

Yes I agree with others on the thread, the reference 670's are too cheap and nastily made for a £300 card, I wouldnt touch one. Looks like the honeymoon period for the euphoria around the 670 is coming to an end, and people can look at the 670 much more objectively instead of just a wankfest over their new cards.

Bhaav, you cant possibly say every single KFA EX OC card is working at 1215MHz out of the box, Im sure they have had a few RMA's as well, just like all the cards. Obviously the EVGA has its problems but it doesnt mean all the others are problem free.

Links please, because I have just checked the nvidia forums and there's no such posts on there - one post from an EVGA owner and one thread from someone asking for Boost to be disabled (which you can do with NVInspector and set solid clocks and voltage)

OCUK is the only place selling the KFA2 EX OC. I don't see anyone here that have bought one and not had it work at the stock settings of 1215 Mhz boost. One person even got one with a 1229 Mhz factory boost. They are working as specified by the manufacturers. Hand picked GPUs, good full length PCB, 8+6 pin connectors, 1215 Mhz out of the box.

I wouldn't touch a reference design for just £30 less.

do you understand what the word "arrogant" means?

if manufacturers send their "absolute best" cards to reviewers, then why does the KFA EX OC that hexus got also struggle to hit 1250

you don't have to go too far to find user reviews of short PCB cards hitting 1200+, there's been a couple in the last couple of pages, so it's a bit pointless me trying to show you any more as you clearly can't or won't read them anyway as you're sat there with your hands on your ears saying "lalalala can't hear you" because it goes against your beliefs, just like you would never accept any clear evidence that BF3 couldn't be run on ultra on 1GB cards... yet funny how all of a sudden you've swapped to a 2GB card that runs at the same speed as your pair of 560ti's did

Agreed. That is why I went for the windforce even though it has a blue PCB. The cooler on it looked like it would really do a good job and it has definitely delivered. Amazing cooler.

 

[psychodil]

I agree about the reference cards. But just because you havent seen anyone on the forum complaining about the KFA2 cards doesnt necessarily mean they are all working as specifioed. They are also sold in other countries as well and some may have had problems that we dont know about. Im not saying they definately ill have had problems, but you shouldnt make statements like that without knowing the facts. I dont know if all the cards made are working correctly and neither do you.

that's not entirely true either

 

[andybird123]

given the choice and based on reviews and what end users are reporting, the windforce is clearly the better of the 2

you are talking to the guy that argued till he was blue in the face that you could run BF3 on ultra on 560ti 1GB cards when HE DIDN'T EVEN OWN A COPY and was telling people who had owned 560ti SLI 1GB that couldn't and had had to upgrade to 1.5GB cards... and has now sidegraded to a 2GB card, apparently for no reason whatsoever

so don't worry, even if you had clear evidence of that possibility he would deliberately misread it or simply ignore it

 

[PCplodder]

andybird123 you seem to be very very defensive of the reference 670's....
Is there any reason why?

They perform well, and they overclock ok. But there is absolutely no excuse for Nvidia using the pathetic heat sink when they already went out the way to make room for a big one by (after cuttings costs and making a small PCB) making a standard sized shroud over the card.
Temps and noise could easily be better (although not a huge problem at all, but could definitely be better and less noisy/stay cooler liek the 680) without completely crapping out on the heat sink.

No hotlinking please!

It doesn't matter what anyone says. A £320+ high performance card should not have a pathetic thing like that on it, specially when there is room for a regular and better quality sink, I see better heat sinks on a £80 card.

When I pay 1/3 of a grand for a card I dont just pay for performance alone, but also a bit of quality. Seems here Nvidia have completely forgotten about quality.

Hey, thougt I'd chip in here since I've been reading this thread since the start. Got my 670 on friday. Was on a really strict budget and couldn't spend more than £330 in total. So went for the ocuk reference card (palit) and so far I'm extremely happy with it. The highest I've had it boost so far was 1202mhz and 6.4ghz memory. Haven't tried to go higher yet as I've been gaming
