980TI overclock...

ternity · 23 Jul 2015 at 19:28

So just got my 980TI today, sadly can't get a very good overclock even with the voltage turned up.

1340mhz boost, 2078mhz on the memory.

Did I just completely lose the silicon lottery or what?

Any advice appreciated...

That's quite high on the memory. If you drop it to 2000mhz can you clock the core higher? Have you increased the TDP limit?

ternity · 23 Jul 2015 at 19:36

Nope, did the core clock first and then the memory.

I did indeed increase the TDP limit. Sadly nothing helps. Could it be the latest drivers? I hear some people have issues with their overclocks after

Edit- weird thing here, in the overlay i'm getting a reported clock speed of 1420 mhz, yet in GPU-Z it says max is 1340. Is this normal?

you got better memory than either of mine. the core is the lowest I've ever seen though, which psu you using

Not sure if I can post but here is my gpu z...

My overlay is reporting 1420 MHZ ingame, slightly confused.

Can I force anything in afterburner to help? or maybe use another program?

Well, you didn't completely lose it. Mine overclocks to 1226MHz on the core (1428 boost) and 1940MHz on memory. And let me guess, you have a Zotac GTX 980 Ti Amp! edition with an ASIC percentage in the mid-60s?

EDIT: Actually, if your overclock is not stable, lower your memory overclock by about half. 650MHz is A LOT. Then try to see if you can achieve higher core clocks.

I do indeed

I feel lucky now, got 2 MSI cheapo reference which can run @ 1520 78 & 71 ASIC's.

1340 is what the basic boost is. This is based on a hardcoded offset from the base value. The actual max boost is worked out on the fly based on limiters and other complex things I know nothing about.

Good work. My 70.3 asic seems to bench well at 1506..but ain't game stable. I think its nearer 1430 for me to be 100% stable in heavy games like pcars.

ternity · 23 Jul 2015 at 20:11

Okay so all in all a 1420 boost overclock isn't that bad? Considering i've managed now a 700mhz memory overclock?

Is that instability power related (hitting max & throttling) - Ive found by putting my power limit stability has increased significantly

If you drop that to +500 (a good overclock) you may be able to get the core higher.

Yeah I hit the power limit quite a bit. But ive set it to 109% max in AB.

The stability is pcars screen freezing and a nvmddlmkm error recovery.

Yeah, I had to flash my bios to up the power limit to incrase stability, but I've got them under water & had to .. do horrible things to one of them to remove the stock cooler so no RMA for me.

I have to say, using a circular saw on a £500+ graphics card to cut through metal wasn't a fun thing to do half way through a build

One slip & I'd have chopped off the end of the board.

That's the thing, I did the core clock first, max I can get is +210.

My heaven benchmark score was 2700, does that seem normal? what do you guys get @ 1080P?

2700 is fine. I get just under 2500 with my AMP Edition @ 1440 / 1930.

use afterburner and run a game for a bit, then check the graphs - that'll tell you your true boost value.

So far i've only got +200/+500 on my ocuk reference and that's boosting to max 1466 with +25 volts, but that's hitting the power limit (106%) a lot and i'm getting some strange behaviour in gta v so i might not be completely stable yet.

Asic 83.9

Decent Asic there.

What overclock should be possible with an MSI 6g with 63.9% asic?

Competitor rules

980TI overclock...
