ULPS & Crossfire & Overclocking

[Chrisoldinho]

Is it safe to overclock with ULPS enabled in CF configurations?

HIS iTurbo gave me a warning that my system would be unstable, however I guess the proof is in the pudding as MSI Afterburner seems fine with it enabled, overclocked and running Kombuster?

Also, I know ULPS disables one of the cards when not in use, so I am unable to see GPU2 temps in MSI Afterburner, is there any way around this?

Thanks,
Chris.

Yes, but it can be a pain when you wan't to add voltage to the second gpu, overclcoking within CCC is with ulps enabled.

Main thing here is don't use Kombustor, it's mainly a stress test that is not good for your gpu at all, use 3DMark/Heaven etc instead.

His/Trixx both want you to disable ulps for stability reasons when adding voltage.

Varied with different AB's/driver combinations for me, sometimes it gives a full readout on the second gpu, other times it doesn't.

You'll want to be on a 13.2 beta driver before tinkering about with ULPS

I found with it enabled I couldn't run certain benches, also got random crashes.

Once ULPS disabled probs went away

ULPS enabled also screws up any monitoring applications you want to run as it doesn't force detect the 2nd card

I still can't get HW64 to recognise my 2nd card

Haven't tried tbh, I can get MSI AB & Radeon Pro to pick up both cards fine now though

Same here, just got some new ULPS software to try and if it works I'll put

a link up

Sweet

Absolutely LOVING my 7970 CF at the moment!!

The only thing stopping me buying a 3rd card is PSU limitations

Waiting to see what Titan proves to be like, if its a no go I'll have a 3rd card.
