The boost is deffo linked to voltage, increase the voltage to +87mv and the boost will go to 1450+ (well on my cards)

NVIDIA GTX 970 OWNERS THREAD

Thanks for the clarification!
Am I missing something in afterburner with my cards? I can see from the thread that a lot of people are getting +87 volts to play with, but I can only set upto +37. I'm using Strix cards, and I think the voltage is really holding my OCs back, as temps are deffo not an issue!
By the way, I haven't read the full thread so if this has already been addressed I apologise in advance.
I'm tempted to drive over and pick up one or two of those Gigabyte G1's, especially if there in stock before lunch time
Why didn't I think of that!? I'm only 10 minutes away. I was all set to go down the route of buying online!

ASUS cards have a max lower TDP and only a single 8 pin PCIe connector.
That limits their max voltage which is what afterburner is reporting.

I had a feeling that was going to be the reason ;_;
Can still hit 1500+ on the core mind when overclocking a single card. Memory doesn't do too well without volts though :/
How long before I can DSR a card with OCUK? 14 days isn't it?

Anyone gone from a 280X to one of these?
I went from a 7970 Windforce to a MSI 970 if that helps

I've gone from crossfired 7970's to SLI'd 970's.

Yes Gigabyte are here, but we've had 100+ pallits and 2 containers arrive today, so I shall have to go book in the stock myself, but I am having a brew first.

Getting 1509MHz boost, on stock volts
How??

Depends on a load of circumstances. If the card thinks it can boost higher depending on volts available, the quality of the silicon and the power limit then it will.
It's not the same as AMD where basically you up the core till the thing shows artefacts.
This boost stuff can be confusing at times.
Also remember cards come with different stock/boost clocks which will play a part.
At +220 on the core my MSI boosts to 1561 with +20mv
If I increase that to +87mv it boosts to 1574

PerfCap Reasons in GPUz are as follows
vRel = Reliability. Indicating perf is limited by reliability voltage.
VOp = Operating. Indicating perf is limited by max operating voltage.
Pwr = Power. Indicating perf is limited by total power limit.
Thrm = Thermal. Indicating perf is limited by temperature limit.
Util = Utilization. Indicating perf is limited by GPU utilization.

I am stuck at the moment.
My core will boost to 1640 when benching but it will not go higher because I am being seriously throttle by the power limit. Plus it doesn't make any difference if the volts are stock or increased.
Its such a shame, the GPU could go further!
Correct me if I am wrong, but a custom bios would allow my to up me power limit beyond MSI's current limit?

Seen this a lot, the cards seem seriously handicapped by lack of power limit and voltage. Hopefully in a few weeks improved BIOS will come out.
I think the good GPU's would be hitting over 1700MHz boost and the worse as low as 1500MHz with better power limits.
Very promising though!

We just need a bios editor that works!
Can't wait to get this card under water with a custom bios

1700Mhz would be insane!
These cards are so cool that personal I can't see how being under water will improve the overclock. Even with the MSI cooler you will most likely hit the GPU's stability limited before you hit the heat limit.
I have a kraken + antec kuhler 620 + enzotech copper heatsinks for VRMS and Ram sitting waiting for a custom bios... Also I need to sort out my hard drives as they are preventing me from pulling out the cage for space for the radiator

It's the voltage. As soon as you start ramping up the voltage temps will increase.
Plus with water and a back plate i'll be cooling the memory chips directly too.

Testing the AIR BOSS COOLER, OMG easily the best yet and in normal auto fan it is so so quiet, amazed Inno3D have the best cooling solution, I AM IMPRESSED!
