GTX 970 overclock results!

[jty0yt]

So on my GTX 970 I have upped the core my 120 MHZ observing a boost clock of 1479mhz. MY fans are around 50 percent at 100 percent usage and the temps are 52 degrees! I have only upped the voltage by 15 MV and the power limit to 105%. I love this card, give me your results below!

 

[Ser_Seishirou]

Have you tried reverting it back to its stock settings?

yeah i put it to stock setting and got around 990 score but after downloading EVGA precision 16 i used that to overclock and got it to pretty high setting and ended with a score of about 2013 for valley and about a 4217 for furmark

Sorry if this has been discussed already, but how are those of you with the Gigabyte G1 Gaming GTX 970 unlocking the voltage control bar in Afterburner? Mine is not changeable by default.

In MSI Afterburner, click the gear icon (settings). Under general tab/compatibility properties, checkmark "unlock voltage control". This will force you to restart afterburner. After you should be able to adjust voltage. Worked for my EVGA, hope it works for your Gigabyte!.

Just finished Overclocking my two SLI EVGA 970 SCs. Got my core to 1480MHz and my memory to 4104Mhz. Increased my Firestrike score by 11% and my Heaven score by 10%. I wasn't able to get anywhere close to this when air cooled, but now that i'm running 50C max load watercooled its way more stable. Not bad methinks.

The "issue" (if you want to call it one) with those EVGA SC cards (which I own too) is that they're borderline with their design and power limit. Means: In stress tests like Heaven they will hit the power limit basically ALL THE TIME until you do special bios modding and tweaking.

Since the card in Heaven and gaming will hit its power limit (even with PT slider all the way to the right in MSI Afterburner) you can WELL overclock the card to 1500 whatever but it will rarely ever actually KEEP this clock, definitely not under stress!

So: What I am saying here...a lot of people might believe they have a successful overclock of 1500 but they wont ever see those clocks active because the power limit will prevent this. (Of course in their tools it says that they set the clock to 1500, but this doesn't mean a lot really if this clock is not really kept when they bench and game...this is just how GPU Boost works...)

1380-1440 is more realistic, 1500 would be very good but as said I believe most cards wont hold this clock under stress.

EVGA GTX 970 SC ACX 2.0

Right now I'm at 1512 MHz on stock voltage (+120). Temps get up to 72 C in FurMark, but my fan profile is set to max out at 50% and it runs quiet, so I'm very comfortable with that. This thing boosted to 1392 MHz right out of the box, which is just bananas. I haven't bothered OC'ing the memory yet.

I read a lot of negative feedback on various forums about how awful the EVGA versions are, but I'm experiencing zero coil whine, and as long as you keep a conservative fan profile, it's crazy quiet. And you can overclock the nuts off it.

FWIW, I ran Heaven 4.0 and scored a 1977 (78.5 FPS) using the default "Extreme" 1600 x 900 setting (not 1920 x 1080; I like to OC using a window and burn-in at 1080).

Mine is DEFINITELY volt locked, there is no way to go higher than 1.212V, even with bios modding. It is my impression that MOST GTx 970 are actually locked at 1.212 and the setting in MSI Afterburner doesn't do a thing.

These memory chips are rated at a theoretic max. 8ghz and I personally would not go higher than 7.9Ghz (which is +460 in Afterburner).

You CAN add more, of course, but the problem is you might end up slower (and not faster) since the chips internally do CRC checks, and if you exceed the specs for the memory chances are you have errors, you just don't SEE them. So don't just blindly overclock the memory and assume things are fine. I would set it to 450-460. 500 is unlikely and 600 would be way too high.

 

[gokitty199]

hows this? so far without touching the voltage nor power limit i was able to get a 1677 in heaven benchmark.
+193 core clock
+200 memory

Havin' an headache with my

GeForce GTX 970 OC Silent Infin8 Black Edition

Currently running +35 Core + 400 Mem

Gives me 3905 memory & 1406 boost which in it's right is pretty darn good but since i'm trying to break 10k on 3Dmark for sake of it.

I ran 3DMARK with core at 1467 boost to get 9957 but it's unstable after awhile, If i change voltage to +37MV on MSI Afterburner it doesn't seem to effect max voltage which is 1.2120V

no matter what i try i cannot get 1500 boost 🙁 instant driver crash also with 4k memory i start getting artifacts.

Think i've just got unlucky with the lottery, 65% ascii

i have an msi gtx 970 single gpu

overclocked as follows

core : +195
mem + 260
PWLimit : 110%
TempLimit : 91
CoreV : +0

core clock total : 1537
mem : 3764
max temp : 58c

although i have to say i dont feel any difference when overclocking this card... in any game.. the fps is the same...

EDIT : officialy tested my OC to make it stable... using Basic valey edition

not sure if this is going to apply to you or not, but i was able to get +195 core clock and +330 memory and have it stable while testing with valley, but when i tried furmark it pushed it much much harder and was only getting +155 core and +330 memory stable. try furmark, arma 3 pushed it a good bit harder than that to

 

[tomashen]

yeah i noticed also, the more memory you overclock, the shittier it runs... :/ at least for me ...
i can set memClock at 200 and go with core up to 230+ and its stable as hell...

but yeah always turn down about 20 on each clocks to be stable every game

My ASICS score is 82.7%
This is the best I was able to get on my FTW+ after about 2 hours of tuning:

 

[DoctaCarta]

What are max voltage and gpu temp for the GTX 970?

 

[LastTulare]

That score was using my card at these exact settings.

Here is the excel spreadsheet I made of all my tweaks. It seems to like +6 MV the best. The trend I noticed, was that 0 MV will give me higher FPS on the min/max, but a higher MV will give me a better AVG and overall score. I never went past +25 MV since some of my results suggested that I either shouldnt, or it wouldnt make much difference since my card didnt like anything over +135Mhz GPU clock and +500Mhz memory clock.

 

[LastTulare]

Im sad tho. EK has no plans to make a full coverage water block for the FTW+ even tho they did make one for the regular FTW. I wonder if I could push it a little more if the cooling was on liquid vs air, that makes for some interesting testing.

 

[tomashen]

here is my excel notes. i never saw any boost with oc with my eyes so i wanted to make this too..

but really its jsut killing gpu faster with no real gains.

 

[DoctaCarta]

Benchmark runs fine but I am having issues playing BF Hardline @ Ultra @ 1080p, however; temps are fine. Any ideas? What about adding more voltage? Thanks

 

[LastTulare]

I know that the ASICS score is a big impact on the actual boost speeds. Figtech on Youtube did an SLI benchmark video compairing two FTW+ cards separately and in SLI. One had a really bad ASICS score and his actual boost clock was lower than the advertized speed. I was wondering how his card still got a higher score than mine, but then he told me that he used the Extreme preset not the Extreme HD like I did. And if you look at my spreadsheet of results, I have much higher clocks than you, without raising the voltage, and all of it was done without needing to raise the power target. I only raised it after my testing. My temps during the benchmarking were sitting around 68 to 71 degrees depending on the scene. What is your ASICS score?

 

[LastTulare]

I am pretty sure I am getting a second FTW+ by friday. I cant wait to run some SLI benchmarking tests. Hopefully the ASICS Score is the same or higher, hopefully not lower than 75% because the slowest card will be the fastest the SLI can run unfortunately.

lol No I dont run mine at those benchmarking numbers either, we know it can scream, but who runs it screaming? thats like saying we know this car can redline at 8,000 RPM but we dont go driving it around at that engine speed haha I turn my GPU down to +120 and my memory down to +300 and keeping the voltage at +6MV for any other time, but only for benchmarking and numbers will I find the max it can handle.

yeah i know, overclocking always turn down for the end.

but ive never used core voltage ... is it dangerous like cpu voltage if you go too high ?

At least is says it does in Precision X. Mine didnt like higher voltage anyways, but it ran better with +6MV than it did with 0 and I dont think 6 is going to hurt anything. I was skimping thru this thread and looking at everyones numbers and someone mentioned that the card has built in protections for over voltage, but why even have to rely on those? I dont even want to risk it, especially on air cooling!

 

[Sergeant_Sneaky]

I have upped my Palit GTX 970 (Stock 1304Mhz/3504Mhz) to +196 Core (1500Mhz). Any higher than that, without voltage causes crashing.
I couldn't up my VRAM at all at first, I put the power limit to 109%, which is the max for mine and I was able to get +50 stable, now FireStrike crashes running that.
How come everyone else is getting around 400Mhz+ on their VRAM and I can't manage 50Mhz stable 🙁

 

[LastTulare]

On mine I bumped up my memory first before anything else to see how high it would go before crashing. 500 was my max. THEN I started bumping up the GPU and the voltage. I cant get my GPU much past 135 or it will crash my entire system for a hard reset :S
