Use GPUZ does under sensors it will show the reason for throttling.

I had this was showing power. I was at 125% in afterburner and using a 750w gold rated FSP psu.

I replaced my psu before i went SLI with an EVGA Platinum 1000w (made by superflower) an i get no whine and no power throttling issues anymore

I assumed power throttling meant the performance of the card was being hindered by its maximum possible power draw that it has (based on its power connections). At least that's what GPU-Z lead me to believe. The card is power limiting itself, not the PSU limiting the card (unless your PSU obviously can't handle it)

That is correct.

you sure it is power trotting not temperature trotting ?

Just to clarify, it was your PSU causing the issue?

CraigN · 6 Feb 2015 at 13:44

With my old PSU i was getting the message VREL in GPUZ when i saw throttling. I tested and got a different message when throttling was being cause by the card hitting 80 degrees.

I was also getting coil whine with my old PSU.

New PSU and no coil whine and no VREL message or throttling under 80 degrees.

So for me yes new PSU fixed it.

VREL isn't power throttling. It's voltage related. VREL = "Reliability. Indicating perf is limited by reliability voltage."

It could have been that your old PSU was on the way out.

I'm at work at the moment but I'm going to do some more testing when I get home tonight.

Strange thing is I only noticed the throttling last night. The few nights before I didn't see this issue. I am running a Silverstone 600w PSU:

I can get 1550 on the core and be stable, but I'd probably dial back to 1500 and be happy at that.

I haven't felt the need to OC even at 1440p. 69 fps and 65 fps isn't that big a difference really?

SS-89 said:
Mine are set to 1500/8000, they can go higher (benched at 1591/8300) but that provides more than enough performance at a relatively low voltage.

Sounds promising, I'll be aiming for circa 1500 on the core then. Cheers!

Sold my msi 970's and bought a pair of ocuk reference 980's they run a bit hotter than the msi cards but games are so much smoother now at 1440p I can finally play watch dogs although strangely it runs better on one card

Bluntwrapped · 6 Feb 2015 at 19:38

Ok so I fired up another run of Fire Strike this time with the power target maxed out to 125%.

According to the above my card needs upto 115% power target when at stock clocks to maintain steady core speed without throttling.

Does this seem normal?

krooton · 6 Feb 2015 at 19:46

I've caved in and joined the crew with an OCUK Reference 980

Love it! Even with a modest overclock, it runs 5ºC cooler at full pelt than my Inno3D 970 did! Quieter too

Dirk Diggler · 6 Feb 2015 at 19:55

@Bluntwrapped

Mine peaks at 73% on stock settings.

Can anyone point me in the direction of the updated bios for the Galax cards? They're too loud idling at 50%.

titaniumx3 · 6 Feb 2015 at 21:17

Has anyone enabled MFAA in the control panel? Is the performance increase good? Are there any image quality issues? Do you turn it on globally or game by game?

Disable the card in Device Manager first

passey89 · 7 Feb 2015 at 09:04

any 1 heard when 349.56 drivers are going to be released?

cHk4 · 7 Feb 2015 at 12:23

Not really sure what I should try and push the HOF to. Can anyone give me + values or Core Clock/Mem Clock please, I wouldn't mind pushing this beauty.

1550/8000

cHk4 · 7 Feb 2015 at 12:52

Thanks mate, am I being thick but I can't actually change the value to 8000, will only go up to 4.5

Dirk Diggler · 7 Feb 2015 at 13:14

Afterburner divides mem clock by 2, so in that image your mem clock is 7010, which is stock.

Do +100 on core and +200 on mem to start off. Then, run a benchmark and see what core and mem peak at.
