970 Overclock Discrepancy

[W-L]

Hey guys I'm trying my hand at overclocking my Gigabyte 970 and noticed my card's Core Clock is higher than the set Max Boost speed set on my overclock. Is this because of GPU 2.0 raising up the boost speed since it hasn't hit it's thermal limit?.

Also for the core voltage on my card it has a max increase of 87mV is it safe to run at that high of a voltage since I've seen many others just turn everything to the max on their card, I plan to run this card daily at this overclock.

 

Let me know if I should change anything in my overclock:

 

 

 

 

 

Small Update:

I ran some more benchmarks and found that with those settings it would cause the Unigine Vally benchmark to crash my overclock 45-50 mins in, I was previously doing 30 min runs. After some more tweaking I'm able to run stable at around an extra 5mV on my core voltage, but just to be safe I backed off my memory speed to +490MHz and ran over an hour with the Valley benchmarks with no problems  .

if its stable at those speeds: WOW.

 

Edit: But yes, thats because of GPU boost.

Wholy mother of god...

THose speeds...

I ran some games for a good 30mins but it started to give me spotting until I raised my core voltage and everything seemed stable, I'll try some more games for longer tonight.

I have the same. I can run about 7800 on memory and about 1550-1560 on core max but in valley it shows up as >1600mhz and in the other tools as shown

Ok I thought it was an error in GPU-Z, did you need to raise your core voltage at all to get those speeds?

[Nup]

Wow, nice OC. Congrats on those!

to change the voltage does not do anything for me. it doesn't go over 1,2v

I will test some ocs now that cooler is just beast/the chip is awesome. love that card

why is the TDP only 80%

 

This can't be during valley....

Yeah Gigabyte sure does have some beastly cards, I plan to watercool it soon once the rest of my stuff arrives, but does anyone know if it's safe to run at +87mV for the core voltage?

I was running the valley benchmark when I took those readings.

Valley pushes 110-120% on mine

It varies from 75-90%, what temps do you get on your card?

About the same as yours. 65-66 ish.

 

Did ASUS put in a Baby BIOS again? Had to biosflash my 670 aswell.

 

EDIT: think i know why though, it only has an 8pin connector.

memory at +1400 and i didn't even finish overclocking. this is where i stopped raising the clock all on air as you see

note: the cpu fan is not the stockfan shown on the last picture. it is a bequiet too

What's your GPU's ASIC quality? I'm only at 63.3% but run stable at 1500 boost and 8050 effective memory so I'm guessing your card is in the upper 80's or lower 90's.

What is the ASIC score for exactly?

[das affe]

75 asic quality for me never heard of that

[bossdre]

OH. MY. GOSH.

 

Got a G1 Gaming 970 and I got mine at +150 core clock and +200 memory clock at +70mV.

 

But I also got the discrepancy, it shows in GPUZ that I only have 1479 mhz core and 1853 mhz memory and while its in load MSI afterburner shows my core at 1554 and memory at 3700.

 

Edit:

 

Mine's Asic quality is only 68.7%..

The 'discrepancy' is GPU Boost. That rated boost speed varies. 

 

Nice clock on the 970. The lower tier card can sometimes push higher than the 980s. 

 

At least you pushed it.

Should I pull it back a bit for everyday use though, and is it ok to push it a bit further to try increasing it's limit with the core voltage?

Ideally keep pushing till the drivers crash or your benchmark crashes then back down 5-10MHz.

It's supposed to be the relative efficiency of the card more or less. How much current it take to reach it's advertised clock speeds I believe. It's an approximate of the overclocking head room of the card.
