gtx 970 overclocking

[ben dover kid]

so i figured out to overclock.. again. few questions came up:

1) i noticed a coil whine type noise while benchmarking, but it wasn't that loud, fans were a lot louder. also it was the same frequency noise all the time. can overclocking cause coil whine that will eventually become louder and stay permanently?

2) i got small(about 5-7%) improvement without increasing voltage. well... what can i say about that? then i increased the voltage and stuff and then i got 15.5% improvement on heaven benchmark score. is that good? does the increased voltage actually make my gpu die so much faster that is wouldn't be worth overclocking?

the current and best overclock is +35 on the core voltage, power limit set to 110, core clock +200, memory clock +350. any good?

Over Clocking the card .

No:1 there is now way you can do any sort of damage on the gpu with over clocking tools. these cards are designed to have safety .

No: 2 When Over clocking and you see the screen acting strange or even going crazy or even a BSOD (blue screen of death) reboot the pc then the seting will be back to normal till you change them again.

No:3 Can you show up a screen shot of the program you use please also the reset to normal settings on the program also take a screen shot of youre current settings then we can advise on continuing in getting better clocks ,how to do it the easy way .

No:4 when testing it takes time to see where the limits on youre card is.

No:5 Every Gpu even if it's the same as another person will have a different Chip then yours .(not 1 chip on a CPU/GPU will be the same nor a clone. EG: say some 1 bought a 6700k CPU and got say 4.5ghz Over clock then you see another person with the same chip get higher .That person got lucky with the chip he/she bought . Is it an issue no not at all. .Show us a couple screen shots then we can help you out. And for good measure in youre replay tell us what youre specs are also thank you.

1.  Yes, overclocking can cause coil whine.  It'll be louder with higher frames.  But, no...it won't become permanent.  In fact, in some cases, it actually reduces it a bit for daily use.

2.  Use GPUz sensors tab to read your core clocks, and watch the perfcap reason line.  The latter is especially important in getting a good overclock.  
Sometimes voltage helps a TON....sometimes it doesn't do much of anything.  The thing to remember about Maxwell is, the voltage limits in the stock bios are pretty low on NVIDIA GM204s, so....raise it as much you want.  It'll likely only go to 1.256v or 1.262v anyway...IF you get that high.  It also depends on the card....ASUS STRIX 970s, some of the reference cards and a few of the GALAX cards are locked at the VRM to 1.212v.  Keep your temps under control and run with it.  Remember, the cooler Maxwell runs, the higher you'll get it to clock.

+200 / +350 sounds ok, but without the actual clocks, it doesn't tell us much.  Certainly a good start!

i use msi afterburner. specs: i5 4690k(stock atm), msi gtx 970, gigabyte z97x gaming 3 mobo, 8GB kingston ram, some shitstastic 700w psu. i did the benchmarking on 1440p screen, far cry 4 runs pretty well and looks awesome. here are screenshots. the core clock was same on both, even tho it rises once on heavy load.  edit: thanks for replying both of you

GPUz sensors tab....ya really need to be using it.

Sometimes it just flat out hurts.
