Good choice on the reference card, they are pure quality and they don't sag either!

Skiddley · 12 Feb 2015 at 17:48

Do the Strix sag?

Sag??

The Strix appears to have a backplate that should avoid physical bending.

I did not even realise cards did that until you posted! Learn something new every day

So far so good using these settings

You may want to test these too:

Power: 122%
+50 Volts
+121
leave your RAM stock, then up to my SIG speed if you are stable.

Report back.

Mine will boost to 1513, then drop to 1500 as vdrop kicks in. I've seen the RAM effects the voltage across the whole Card, so start with your Core first.

Just run heaven with the GT's and side fan, dropped the top cards load to 69°, that's a 10° drop from before! Well happy, now to over clock properly.

I'm finding Perf-Cap in GPUZ to be extremely unreliable so I wont use it any more.. It was detecting volt issues every time the screen went black in 3DMARK to load the next scene... In watching 3DMARK the volts nor the clocks dropped once!!

If anything my score went up and my power limit reached a peak of 110%!

Thanks a lot Awahwah for all your help

Coolies,

Now try to reduce the Voltage a little. You should find a nice medium, for me that was 1500/7700 @ 1.2 volts after drop. Which, if you think about it, is good for any 980. Anywhere around 1.2 - 1.225 I'd be happy with as looking in the BIOS Voltage table, 12.8 seems the max - not that I'd want to run it at that.

RAM clocks just seems to effect the Core clock and stability. I don't know why, but that just seems to be the thing with my SOC.

Anyone running two G1's?

Already have one and likely picking up a second tomorrow. I have decent airflow in the case.

I'd be interested in what temperature the top card reaches. What temp is your single card doing at the moment, 70 at peak or thereabouts?

1535 MHZ / 3758 MHZ 1.25V, 110% TDP

You've been here long enough to know that images over 1,280 pixels wide should be placed in spoiler tags.

Just about the same as my Card

Now that's just greedy!

I'll be interested in what you think of 2 in sli and what performance boost you get.

Had what looked like texture flickering in Dragon Age Inq, so I've dropped to this 1520/3700 which has solved it. Which isn't a huge amount and still a great clock

Glad you found your stable clock.

EVGA Hydro Copper owner signing in.

24 degrees idle. High 30's now in SWTOR. Love it so far, need to push it over these coming days.

olliej82 · 12 Feb 2015 at 21:20

In gpu-z I'm getting perfcap reason pwr. sli, does this mean my psu isn't strong enough for my sli 980's? It's a 750watt 80plus bronze

You're probably power target limited try raising it a bit

Problem is I need to keep the temps down, this cooler is awful... As soon as it hits 73C it throttles back about 20MHZ.

Yes well, once in what 6 years people forget

It's here and all in what diffent in games

Been reading through this thread tonight about creating your own tweaked bios.

http://www.overclock.net/t/1517316/...d-980-firmware-zosons-h2o-and-air-custom-bios

I dare say I'll give it a go knowing me.

Some people are getting some amazing overclocks with the G1 in this thread. Glad I have gone for this card now. :cool:

Looking forward to having a play with it!
