I have recently OC'd my gtx 970 and this was the max I could go without crashing, or locking up. And I'm just not sure if this is actually stable or possible! So here are my questions:

1) Is this a safe overclock (temps are fine / ek just released a waterblock for my 970s so I'm fine) but I mean for the gpu / memory is this 2+ core speed safe?

2) how can I test to see if the gpu is down throttling on me in case it is

3) if this isn't what you recommend how much should i reduce the OC speeds?

evga acx 2.0 gtx 970 voltage hasn't been touched it is stock. Ran multiple gpu benchmark software and did 2/3 passes on each one. And for everyone saying these cards are loud and make a whining noise I have to say mine are very quite even at this OC'd settings my fan curve is set to auto and gets no higher than 41 and its still not very loud! I absolutely love these cards and kinda disappointed everyone bashed evga on them!

here are pics of my overclock settings and benchmark scores!

First, you mean Ghz not Mhz. Its already running at over 1000Mhz.

Second, no you cannot run it at that speed stable, at least not for long. The people who managed that clock speed used liquid nitrogen poured directly onto the GPU to cool it, which needs to be constantly refilled as it heats up and evaporates. It is only something people do for bragging rights, not actual usage and they only do it for a short while.

While overclocking a card a great deal definitely can yield some impressive performance gains, it comes at a price of reducing longevity of the card as the card will have to work that much harder than it was designed for. I read about other people who have gotten the card to 2GHz stable. The question is, How long can one run it like that before they burn out their card? I would dial it back to 1500/7900 on stock voltage as a safer alternative. If you run a water block, then you could run higher clocks than that safer.

I hope that helps.

Yes it helped a little bit! I have a few questions. 1) my temps never got over 64 degrees on this OC and I tested the card for about a hour. And My entire PC is a custom water loop and Im just waiting on my waterblocks for these cards and they will be watercooled as well! Now as far as me watercooling them does that mean I can stick with this OC and be good and no worries? The voltage on these cards hasn't been touched I left it at stock, I just raised the power limit to 110% and according to MSI the cards only used 107%. Im new to overclocking in terms of what is good, safe, or better. I know how to overclock I just don't know what results one should look for / safe overclock speeds!

well just FYI the cards never got above 64 degrees air cooled. Once my waterblocks for these cards get in I bet these cards don't get hotter than 40 degrees as for my previous cards never got above 36/38 degrees on my custom water loop. So what you have to say about that?

Liquid Nitrogen being poured directly onto the card and only for short periods of time with requiring constant refills is much more capable of cooling than any waterblock you could ever run. Liquid Nitrogen has far more cooling capabilities than all of the water cooling radiators in the world glued together ever could. It is a matter of physics.

Your current overclocks may sound good, but first, it could violate the warranty on the card, and second, I wouldn't recomment much higher than 1500/7900 as safe. But, Lets say the warranty stands, While you send your card out and wait for a new one, you are without a card in the meantime.

I mean, You can run it at whatever you want. It is your card and I can't tell you what to do. But, If you are looking for advice, even at the great current numbers you have your card currently running at, I wouldn't recommend them for long term use. Even if you struck the silicone lottery finding the best chip in the world. The risks far outweigh the gains.

I still remmeber when people used to overclock the 590 GTX's and they would start on fire and blow up, taking other components with it, usually the motherboard, power supply, the card itself, and sometimes even the processor.

If you want more performance than your 970 with a moderate overclock, buy a second one and run them in SLI, or take it back and buy a 980. I am all for getting the most amount of performance for your money. But, I just don't want to see your components in your computer get burned out prematurely due to excessive overclocking either.

What about the vcore? how much did you raised it?

okay but my temps are completely fine they dont go over 64 degrees under the benchmarking which is safe really. But my cooling isnt a problem or wont be. Yes i understand that nitrogen is cooler but that was never the question. I do have two 970's as you can see if the pic links i posted! And this was the most OC i was able to get out of them! and thanks for the advice but you have "7900" as a recommended setting.. but thats way over the setting I have did you mean 1500/1900? But thanks for the advice!

voltage = factory stock
core went from "0" in msi to "510"
memory went form "0" to "610"

All I am getting at is that you asked for advice as to whether your GPU current overclocked speed is safe in regard to your overclock for the 970, And even though I can't tell you what you want to hear in that "Your current high overclock is a perfect level for what the card should be at", it is what it is. You can try to justify to others to believe you all that you want that your high overclock is safe. But the truth is, only time will tell. And the more that you seem like you are trying to convince others to believe you that your overclock is safe, the more and more it seems like you are just trying to justify it to yourself that it is safe.

Did you run Furmark?

Did you hit apply? I find it hard to believe those settings are stable and only 64c

Check your load clocks in the MSI afterburner monitor

yes i hit apply and even got the saved to a profile.. why i posted a pic of msi afterburner and the benchmark score etc. if you look at max frames its 350 and frame rate 184. And if i apply anything over 510 and 610 computer locks up or monitor loses signal. so 510/610 was the max I could have set and still run benchmarks

yes i ran furmark! and 3dmark11, vally, and heaven. As far as temps I know the card is safe and when I add waterbtlocks to it it will definitely be safe! But really all i came here for was should I play games at this OC setting or should I just back it off. I just wanted to know if running at such high clocks was safe to do on my card as long as temperatures didnt get high!
