Overclocking questions

[masked106]

Hi guys

 

got a 970 I'm beginning to overclock. and yes I did consider an R9 390 but it was more expensive, expensive enough to not justify the tiny performance increase.

 

I have gotten so far:

 

+125mhz CC

+400mhz MC

+10mv

 

sometimes (occasionally) the game I'm playing will give a grey screen and after 10-15s say that the display driver stopped working and has recovered. is this this considered a crash?

what max temps should I be looking at? 84C? just so I know what headroom I've got.

I wanted to apply an overclock of +150mhz, +600mhz MC, +50mv. what would be the maximum amount of safe voltage to give? ive seen benchmark sites state that they give +70mv??

 

I'm new to the masterrace as I only got this PC 3 weeks ago and I came from the PS3.

 

P.S OMG THE QUALITY UPGRADE IS FREAKING AMAZING. RISE OF THE TOMB RAIDER LOOKS BEAUTIFUL

When the display driver has stopped working it crashed.

My max temp for OCing is 75-80C  (I have never hit that high but thats my max)

try to stay there

Try adding more voltage to this current clock and see if its stable.

90c is a safe "ceiling" for temperature on the GTX 970. Likely, you'll be able ot stay under 80c. Maxwell is stunningly good at staying cool. If your display driver is crashing, you'll want to underclock a little bit, as you might be pushing your card too far. Try +100 CC, and +375 MC?

Graphics card overclocks crashes due to 2 reasons

1) Not enough voltage to power the current OC

2) Simply pushing the card too hard

 

In his case, hes saying that he only added 10mv, therefore I would suggest for him to push the voltage up to see if its able to sustain its clock.

He asked if 84c is safe, so I refrained from suggesting further voltage. I'm not sure if those are the temperatures he's at, so I took the "better safe than sorry" approach.

Ah I see. Didnt see the 84c. My mistake.

I'm not getting 84C I'm getting above 75. I'm just wondering at what point should I stop Ocing.

[masked106]

should I maybe try +150mhz CC, +600mhz MC and maybe +30mv??

When it stops scaling. Maxwell doesnt scale well with volts, it scales with cold, if you were to get it under 60 You would get even better results. @Darkman@Gofspar

90c is a safe ceiling. If you're comfortable, continue to bump up your voltage until you get it stable.

so should I say 85C would be a good maximum??

90C under the most intensive load you can throw at it.

No problem! Glad I can help! Let me know how far you can go!

I can get +25mhz CC, +600mhz MC on +20mv. if I try 150mhz cc on 40mv its not stable. +125 cc gives me a boost of 1479mhz

how cute

 

my former 290x hit 92ºc underclocked
