Hey Guys,

Would like some assistance on overclocking this card if possible please. The card is factory overclocked to 1006Mhz Core (Boosts to around 1188Mhz) and 1552Mhz Mem (1.175V load).So I'm using the EVGA PrecisionX tool, which has some new features present for these 6** range cards, which I believe to be 'Boost' and 'Power Target'. I've setup a good fan profile which keeps the card nice and cool, and noise levels acceptable (considering i wear headphones, absolutely fine)

I start with running heaven in a window and keeping the card at stock. Heaven puts the GPU load at a constant 99% and win loop forever.

I'll then open Precision X and bump the Power Target from 100%, to 111% allowing the card to use 111% TDP.

Next I'll do what I consider a moderate? overclock and bump the GPU Clock Offset +60Mhz and the Mem Clock Offset +150Mhz.

The card will then perform at:
1238Mhz Core
1625Mhz Mem
1.1750V
Temperatures etc are all okay. However heaven will crash after a couple of minutes? In the above procedure is something wrong?

Any help would be great!
 
Set the memory to it's default out of the box frequency and work on finding the core's limit first.

If heaven is crashing you've overclocked too far. Probably core as memory will articfact before it crashes heaven.

Okay, Dont need to faff about with voltages I guess? With this Power Taget addition?
 
You can't change any voltages on this 670. As for power target, if you monitor it in afterburner during heaven you may find you don't even come close to 100% anyway.
 
You might need to force a manual voltage, though check gpuz sensors while stress testing, if it says 1.175v then you are at the cards voltage limit already (as most are). On occasion a card may be running at below that.

If it says 1.175v then you don't need to faff about with any voltage controls, for the most part the higher TDP is pretty irrelevant too depending how well the card cools

Yep full load always is 1.175V. Yeah I've noticed TDP never exceeds 100%.

Okay, i'll get the core max, and then work on the memory max.

Thanks All
 
98% is maybe starting to toe the line, so in your case the 111% TDP may be of benefit. On my 670 WF under air it would sit at a max of 86% and water a max of ~72%
 
So far things seem better. Increasing core with increments of 5 each time heaven completes, and it seems to be surviving a bit more now tbh.

Hopefully it clocks well. Thanks for your help guys

Since your using Precision X, you can do it with that. Just go into settings, monitoring, click on what you want to show, make sure it's ticked and then press 'show in on screen display'.
