Thanks for the support, hmscott!
Based on your experience, what memory clock would you recommend to go up to, for the core-clock increase of +135Mhz, before it's unstable? Any idea?
Thanks again!

Hi, i got around 750 points with my 870m original clocks. Do you know how much oc could i use with this card?. I dont know what numbers to use there.
Thanks!
SDEagle/TulnukaWara, in my experience with OC'ing Nvidia, but not having experience directly with the 970m/870m, I would google for others experience - maybe check youtube for videos of 970m OC'ing to get an idea of what others are seeing first.
If no references were available, given previous experience, I would start by OC'ing 1 setting first, the GPU frequency, and try +135 as that is the normal limit set in the vBIOS for OC'ing the GPU clock.
If the tools for OC'ing allow +135, then that is a good sign
🙂When the GPU frequency setting is stable then I would work on the memory frequency. Given previous experience, last on the G750JH/780m, and my OC settings of 932/6250 - +135 / +625, I would start at +400 for memory and see if that is stable.
Getting a stable memory frequency takes a little time the first time, if you have no outside references. But it is a simple method. Try changes of +100 starting from stock, and keep going up by +100 until unstable - Nvidia driver crashes or display gets squirrely with horizontal lines or sparkles. Then back off by 1/2 or 50mhz and try again, if stable go up by 1/2 or 25mhz and see if that is stable, etc.
It's not hard, you just need to try increasing/decreasing till stable at idle, then run a stress test like Furmark or Unigine Heaven and make sure it stays stable - then back off or increase another increment.
And, don't forget to post your results, original stock frequencies then + values and final frequencies. I looked for some here, but didn't really find any to recommend. I did find this early post for MSI, and the number should be usable as a base.
For the 970m read the paragraph between the table and the result image. +135 GPU clock and 6000mhz memory - another says 5800 memory, so those are good targets

http://rog.asus.com/forum/showthread.php?52467-Got-your-new-G751JY-G751JT-G751JM-Post-your-review-te...TulnukaWara, I didn't see any good 870m numbers here as the Asus GPU Tweak for Laptops doesn't support direct +frequency settings, only the non-Optimus Asus GPU Tweak for Graphics cards works with the non-Optimus G751JT/JY and G750JW/JX/JH
But for the 870m you can use MSI Afterburner and give +frequency settings there. I would do as above without reference of others, +135 GPU first, then scale up the memory frequency by +100 increments until unstable, and then backoff by 50 and up by 25 at a time - be patient, it takes time.
And, please post your results here
