GTX 970 G1 throttle

[Trashcan]

I think I found my 24/7 stable clock at 1554mhz at stock volts. I've been using that for the past week with no crashes or artifacts. So to make sure its even more stable, I lowered the clock to an even 1550mhz. After playing Far cry 4 at 1550mhz, I noticed it would downclock to 1538mhz after 5mins. Im using stock volts and power % never goes above 85%. Temps also never go above 65C. Any reason it would throttle at 1550mhz and not 1554mhz? Remember im at stock volts.

Thats at stock voltage? Holy crap thats amazing.

I think GPU-Z or some other program had a functionality that would tell you what was throttling your card, im not sure what program it was.

Also you can try upping the voltage or mem clock a bit to see if that stops the throttling.

I just dont see how it wasnt throttling at 1554mhz, but its throttling at 1550mhz now. So far ive kept the mem at stock while I find a stable core clock. My stock volt is 1.218. Thats normal right?

I need some answers please

that downclock is so minor I would stick with it.

 

or just bump the voltage slightly (although I think gigabyte is voltage locked)

Yeah thats the factory voltage, its safe.

But sometimes GPUs do weird things like that, downclocking at 1550 and not 1554 can just be one of those random things.

Just try to increase the voltage or memory clock, otherwise just leave it at 1554MHz.

Add voltage to it. If it still throttles, then downclock it a bit more. Losing 2-4 fps ain't gonna hurt right? What's your memory clock?

I just tried it with mine and with Furmark (really sucks the power) mine was tripping the default power limit (peaking at about 108%), it would also downclock to 1538MHz (it actually bounced around 1550, 1542 and 1538 but I didn't run it long so once it had heated up fully it might have stabilised at 1538MHz), are you sure its not spiking up there? Mine is with the stock voltage of 1.200V but that can be set higher or lower at the factory depending on the silicon quality so I'd say yours is normal.

What's adding voltage going to do? And I've left my memory at stock while I find a stable core clock.

I'm sure it's not spiking. Tdp never goes above 85% for me

It's a few MHz... probably just nvidia's algorithms downclocking for one reason or another... not a big deal...

I have really bad OCD
