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!

How does 1000+ MHz on core & mem sound + 37mv on voktage ??

That's what my card was running at for 2 days without me realising when I updated to the latest nvidia driver & MSI decided to max & apply all settings.

Props to my exoc black for managing to not kill itself under those clocks.

Didnt even notice till I started getting artifacting & insanely high temps - thank god I had vsync enabled - it likely saved my card.

How did the card take two days to start having problems at that clock? That's crazy.

I don't think the EXOC black will add any voltage, no matter what you do on the slider. Pretty sure it's locked at the VRM to 1.212v.

+1000 offset on the memory....not sure, but I think the stock settings would be for 3400, so it was running at 4400. Base clock rate of 2200....you either didn't do anything graphics intensive at all during those 2 days, or, you got some golden memory. I've seen Samsung memory run that high during benchmarks, but....it's in short bursts...

^ in all honesty I'm just glad it didn't destroy my card mate.
It is a little beast of a card though, I did have the core up to 1820mhz stable in the past,& + 450mhz on the mem.
& no not played much over those 48 hours luckily or the outcome could have been bad - bit of rayman legends & Lego star wars.

Keep checking my clocks every couple of hours now - put me on edge a little :-/

Use MSI Afterburners overlay and just have it over your game with your temps and clock speed, that's what I used to do 😛

You can't sell it if you kill it haha. I use F8, much easier to get to.

1820 on the core? Care to post a GPUz sensors tab screenshot of that fairly unbelievable clock speed? Under load.....

I have a gtx 970 G1 gaming http:// this is my score but i have a bad cpu and well i got boost clock of about 1600+ something with +150 on core and +500 on memory and +0,156v and i could get higher cause i did not set it on it's max to see when i can't overclock anymore thought I will test to see it's max when i get a better power supply and a better cpu

PS: And I have no idea how i manage to make it go boost i think it was 1665 or 1666 that time cause i can't get it to boost more then 1554 now i think it derpt that time ore something cause I'm certain that I'm using the same settings now 🙁 at least temp it not going above 59 in FurMark http://

so I just did my first overclock, I got my 970 gaming edition to +226MHz core clock and memory clock to +510 on Afterburner without adding voltage, before the gpu boost its at 1340 core and 2008 memory, with gpu boost it gets up to 1479. do you guys think I could push that farther safely by adding voltage? also the temp in the heaven benchmark would hover at 67-68 after about 30 minutes. please let me know if anything doesn't sound right here, all feedback is appreciated thanks!

on your stock bios you can add as much voltage as you please. you will never be anywhere near dangerous vcore. but the extra heat may end up hitting your temp throttle point which will cause you to throttle which isn't ideal.

set a fan curve with a noise level you can tollerate and keep going with voltage and frequency until you are right at the edge of temp throttling.

there are too many safety nets built into the stock bios to allow you to damage your card. though this is assuming you have good case airflow and you are not suffocating your card.

Hello,

Palit Jetstream here, I have increased to:

Power Limit: 111
Core Clock: +150 (1516Mhz)
Memory Clock: +500 (to 4001)
No voltage increase.

And the results in Unigine Valley:
FPS: 61.0
Score: 1536
Min FPS: 26.4
Max FPS: 128.7

Seems pretty stable for now, only thing I'm worried a bit is the temperature, hovers around 76C (sometimes 77C) in Unigine Heaven with the fan at 75% (created a custom profile). Raising the fan speed more it kinda gets noisy and I'd rather keep it somewhat quiet. Also, even not overclocked I get the occasional 80C while playing but using factory cooler profile. Most reviews said that Palit runs hotter than most but I'm still a bit worried. What do you think? Safe to keep it like that for daily use/gaming?

I've seen a golden card run 1730 on the core, but....1800+? Were you using LN2? What software were you running that was telling you the core speed? MSI AB? Cause....I'm not seein it, not without hardware voltage mods and some serious cooling.

I currently have the Asus Strix GTX 970 and I could only achieve a +120mhz on the core and +600mhz on memory effective. Much much lower than others, but maybr because I have 2 of them in SLI.

My GPU OC software of choice is the ASUS GPU Tweak 2.

I overclocked my EVGA GTX970 SC and just stopped at 1500mhz. I settled with + 134mhz core and +250 mhz on the memory. Looking at everybody else's numbers I feel like should clock my memory higher, but I'm not sure if I should or shouldn't..

Click to expand...

1500Mhz is a good oc especially if you on air. My old msi 970 was running 24/7 1582Mhz on core but vram would only go up to 7800 Mhz. On the other hand my new 980 would go all the way to 8292Mhz on vram. It all depends how lucky you'll get with the chip.
Btw I'm always on full waterblock and bios overclock so do not compare to stock air.

With the STRIX 970 you're limited to 1.212v...nothing will raise it, not even a bios mod, so, you likely won't get a whole lot more out of it, depending on the ASIC.

Should I mess with the mem overclock or just leave it at +250. It looks like I could easily get to ~500.

The memory overclocks are highly dependent on the type of memory you get. Samsung overclocks the best. Elpida is pretty decent, but you have to keep it VERY cool in order to get good clocks out of it consistently. Same with Hynix, except the Hynix usually caps out at lower than 2100.

Push it as far as you can for benchmarking....for an every day gaming clock, there's no need to run it any higher than 1900 base.

When you say dependent on memory are you talking about my actual ram. I'm using 16GB EVGA SC DDR4 2666mhz.


Sorry if that's obvious I'm new to overclocking...

Yes I agree...that is the case. GPU Tweak has the option to increase voltage up to 0.090v but the max is 1.212v
Though my card(s) does not want VRAM overclock. I could get the core up to +150mhz stable and when I mess with vram, it creates nightmares. 🙁

I usually stay away from vram OCing as I am a noob and I'd like to only deal of one factor for ease. This is my first attempt on trying VRAM OC, but then the vram OC gods are not cooperative lolz.

Don't add voltage to the memory. You should be able to run it at 1900 for a daily clock. You may need to create a custom fan profile though, to keep it cool.
