Hi.

I bought the 670 that was on sale for £199.99 a couple of weeks back. Now ive heard these are good at overclocking. Thing is ive no experience with overclocking graphics cards. I have MSI Afterburner.

What do I need to do to clock the card safely? Just want to see how well it clocks really.

Cheers.

Alex.

P.s. Wish id held out now and got one of these melon 680s!
 
To be honest if the 670 you have got turns out to be a better clocker than the 680, it will be just as fast really. Plus the PE has the twin frozr IV rather than the twin frozr III
 
Okay. How do i overclock it? What variables am i changing and how do i test it? I've never clocked a graphics card before.
 
You can *try* unlocking voltage control in afterburner but it will not do anything meaningful, you can't adjust the voltage in any worthwhile way.

The card will likely O/C a bit on stock volts though.

Whack power target to max it doesn't apply any extra voltage so can't hurt the card.
 
Okay I only managed to clock the mem offset to +75

As for GPU clock. If I give it any + offset at all then it crashes the heaven benchmark.

Have I been given a bad card? I thought these were supposed to be able to overclock quite well? Maybe I should return it.

My boost GPU clock goes up to 1098MHZ which I guess is more than the quoted 1079MHZ. I was hoping for more though.

Sounds like yours is even worse than mine was! i think it is a bit of a con with these new kepler cards with their kepler boosts. Some people get stock boosts of well over 1200mhz where as you aren't even getting over 1100mhz...this would equate to roughly a 10% performance boost, yet you both paid the same and neither did any overclocking.
 
I'll try again but it didn't pass the heaven benchmark. I should get around 1200MHZ you think? I've had the card over 2 weeks so can't send back now unfortunately.

Well, it terms of fairness you should :p. In the thread with these cards many people were getting stock boosts of 1200mhz+. Mine only went to 1150mhz and would not go any further.
 
I am only using FSX anyway which I know is CPU dependant. So I'm not that worried that this 670 I've got won't clock that well.

Just a bit annoyed that if I'd have waited another two weeks I could have got a nice 680 for not much more dough!
 
Well unless the card is being used at least 70-80% or more I don't think it will boost to it's maximum. Playing older games mine lounges around the 1019MHz or even less.
 
I am seriously suspicious of overclockers now after they kindly agreed to swap my GTX 670 PE OC that wouldnt overclock AT all.

I received the replacement back today but i am pretty convinced that it is exactly the same card.....It has the same ASIC quality reading from GPUZ. It also has EXACTLY the same boost clock behaviour. It boosts to 1136 then after a little while it will go up to 1149mhz. This is exactly the same as what the first card i was sent did....

The chances of having two cards with exactly the same asic quality and kepler boost is rare...probably impossible.

I realise that overclockers were good to accept a replacement when it did technically work at stock clocks but i bought this due to Gibbo saying these were the cards to get if you want to overclock. Well neither this one nor the "replacement" overclock at all..

I am pretty unhappy right now to be totally honest and feel like OCUK have tried to pull the wool over my eyes...
 
Ask them to send you the card I sent back :). Boosted to 1241MHz by default. My case couldn't handle SLI though, temps too high and fans too noisy.

I must have been lucky, as my first card also boosts to 1241MHz by default.

I know, loads of people who i know bought these cards get 1200mhz + stock boost easy. i would put money on the cheaper non overclocked versions being able to get 1150mhz boost as well....

Very nice clocks!

I have one of these cards as GPU2 and I think its default boost is only around 1150. I think something around 1100-1200 would be normal?

For the record/by comaprison, GPU1 is an EVGA FTW2 and it has default boost clocks of 1210.
