NVIDIA GTX 970 OWNERS THREAD

IIRC the power target doesn't make that much of a difference anyway compared to voltage. When unlocked bios or afterburner commands come along most cards will be on a level playing field for max power target and volts.

My MSI does 1600mhz boost and has only 110% power target.
 
Check the sensors tab to see what it's really boosting to. At +155 it's probably around 1500mhz.

Memory you should be able to do +500, that puts it at 8000mhz which everyone seems to be hitting on Samsung memory.
 
Anyone got a good OC guide/tutorial (using MSI afterburner) for the 970?

What do you need to know?

It's pretty simple, if you're going for max OC, max the voltage, max the fan and go up in small increments +20mhz until firestrike crashes then back it down till it's stable. When it's stable you can try lowering the voltage by 5mv and see if it's stable at the same clock, sometimes you don't need all the extra voltage to keep it stable.

Just did it and crashed out at 1560 core :D Think I'm asking a bit much with SLi and an insulated case like mine :D

I'll keep fiddling..... :)

Was that with +87mv and was 1560 the proper boost clock? You need to check in the sensors tab in GPU-Z to see what it's really boosting to.

Adding more voltage to my cards made little difference to the limit of the clock if I'm being honest. I think I got like +30 core with max volts over my max stock volts clock.

It helped mine, could only do around 1500 on stock, can do 1600 with +87mv. Temps hardly changed and the fan at 100% doesn't bother me, it's the quietest cooler I've heard.
 
Xraycat, I've settled on very similar clocks to you at the moment - 1460core and +200 on the mem but that's without touching the voltage. If I can get to 1500core for 24/7 with a little fiddling then I'll be more than happy :cool:

You checked what it's boosting to? 1460 boost on the 1st tab of GPU-Z isn't what it actually boosts to. Should boost to around 1560mhz in a game or benchmark.

Yeah it froze half way though with 2000mhz @ +20mV plus artifacts gah

Try +87mv, if it works lower it till it crashes then raise it to the voltage that worked. Or just leave it at +87 like I do lol.
 
Won't that require a lot of power or be bad longterm?

No, +87mv is nothing and will hardly shorten the cards lifespan at all. It's only when you start messing with custom bios and voltages you need to be careful, these cards don't even get that hot when overclocked. Does anyone know if the VRM's have decent cooling?
 
I wouldn't say the cooling is a lot better on the Giga, the two large fans on the MSI work wonders. Even at 1600mhz core I've yet to see it break 70c after long periods of gaming. It's also likely to be quieter with less and bigger fans. You can't go wrong with either though and the back plate is a nice edition on the Giga but didn't interest me.
 
I've took the +87mv off mine and running it at 1500/2000 stock voltage with 110% power and priortised for temp. This way GPU-Z tells me the PerfCap reason is Vrel which means more voltage required, if I add voltage it then splits the PerfCap reason between Vrel and VOP which means more power is needed and for some reason the card will throttle to lower clocks and voltage. Not quite sure what's going on to be honest. Afterburner might not support these cards properly yet.
 
I will have lower overclocks but this is a compromise I will make.

Not necessarily, it's more down to the chip than the cooler how far it will overclock (apart from watercooling of course). When GIGA say their 970's are cherry picked they just mean they will all do the advertised boost clock. They won't of tested everyone at say 1600mhz.
