trek554so clueless and a jerk? you dont get tearing and stuttering from hitting the TDP limit no matter how many times you repeat it.
r0achtrek554you have absolutely no idea what you are talking about at this point. even a card working properly will throttle in various scenarios because that is how they are designed. no one should ever see stuttering because of that unless the card is defective or there is driver issues. and screen tearing has zero to do with throttling and is only related to vsync. Seriously are you 10 years old? I posted actual evidence of GPUZ graphs showing the gpu utilization issues where the EVGA FTW card could not hold 99% gpu utilization in Lichdom while the Gigabyte card could. The issue was fixed by raising TDP. If you for some reason think I'm lying about this also causing excess tearing and stutter, the GPU utilization issue is plain as day to see and how it was also fixed by raising TDP. It's 100% my word vs yours and I actually posted proof and you have 0 proof of anything except childish name calling. Do you own a Gigabyte 970 and an EVGA 970 to compare the two either like I did? No? didn't think so. If you're going to tell people "they don't know what they're talking about", you should try to avoid using caveman English with no capitalization, while also starting all of your sentences with "and". chrcolukmy FTW gets to 1531mhz during unigine benchmarks and stays pegged there, no stutters, no jumping up and down. So on a website with much more knowledgable people about overclocking than this one, Overclock dot net, people overclocking MSI 970's with a 220w TDP limit were getting throttling at 1500mhz, yet you want me to believe your EVGA card doesn't throttle at 1500mhz with only 187w TDP limit? I suppose it might be possible, but it would be comparing the worst binned MSI on the planet vs the best binned EVGA on the planet if true, then still probably not likely. Either that or you're using the wrong game to determine just how much power the card can draw. My EVGA 970 FTW needs 196watts to not throttle at 1400mhz in the most graphically demanding games. I'm running an EVGA Supernova 1300w PSU with a single 970 GPU card so I'm not exactly straining my PSU here...

MorphevzIt may be wise to bring the discussion to a mutual respect level, folks. =)
mrblue81Maybe you didnt see my post over on overclock.net.This is what I see after flashing your BIOS. TDP hovers around 78-82% but doesnt go much higher, and the card is still capped out on power. If your BIOS worked wouldnt it be able to go to 100% without capping?Anyone know of any BIOS that are out that can help stabilize clocks? Some games it runs fine at 1513mhz, but more demanding games it tends to clock down to 1420-1440.

Remember his BIOS increases the TDP cap (220w, I believe from stock 170w). If your test wasn't TDP-limited then it's normal for your to see a lower TDP usage with his new BIOS. Someone please correct me if I'm wrong.
mrblue81Maybe I don't understand fully, but why would I still be throttling due to power if I was only using 80% of TDP?
thebskiNot to pile on here, but throttling would never cause lower GPU usage. It would have the opposite affect. If a card down clocks due to reaching power limits then the card is effectively slower which would raise the GPU usage given the same work load. Anyways, carry on.

mrblue81Happens in almost anything I run. When I took that screenshot I was running valley. From what I'm experiencing it feels like the TDP has been raised but the card thinks the old power limits are still in place, so when it reaches the old limit it starts to downclock because it doesnt think any more power is available. I've never had this issue on any of my past cards (gigabyte 670/780 and evga reference 780ti).
bain64In theory I would agree that should be the case, but it appears that when reaching the TDP limit (and the subsequent downclock) there is a spike downward in GPU usage (dropping frames?) before it quickly recovers. This is just my view from looking at my card, not claiming to have done any kind of large scale testing.
bain64 Do you have the 970FTW? Did your power consumption graph drop from near 100% before the bios change, to the current screenshot you show after bios change?If you change the bios switch back to one of the default ones, do you still get the perfcap reason? Does your power consumption % go back up to near max?
mrblue81 Yeah I have a 970FTW, with the stock BIOS I see 100-105% TDP and the same power cap.
bain64 Strange, I cannot reproduce on my end. Is anyone else getting the "Perfcap Reason: PWR" under any circumstances with stock or modded bios?
