r9 380 4gb gigabyte core clock

[Onix87]

Hello,

I have this problem with my core clock on this GPU. In games like crysis 3 and far cry 4 etc. which are gpu heavy games core clock speed fluctuates between 920mhz and 970 mhz. It never even hits default 990 mhz. If I put power limit to +20% in CCC the problem goes mostly away and its almost constant 990 mhz core clock. My PSU is Gigabyte Greenmax plus 650w, with estimated 600W on 12v rails. What could be the problem? Some people suggested it could be the gpu bios... Please help :/.

Hello, I'm pretty sure you may have a bad PSU or 8pin cable, since it supposed to delive enough power for you. I usually set at +10% the powerlimit with every card I owned and I own the same card. I never had problem with it

I have the same problem here,and many others too.it's not the PSU.I just tried my old 280X vapor X and it runs always at 1100mhz without drops.The 380 from gigabyte suffers from thermal throttle even from 55C.The problem will be fixed if they release maybe new bios.The problem is that not every 380 G1 does that.So it is either the bios or a defective series.i got mine back for RMA i hope they accept it and give another model.

Yep, similar here - while I can reach 990Mhz at 0% power limit it is mostly hovering around 950-970 Mhz. 
I agree that early thermal throttling is the culprit.

So any news about this.?
Gigabyte answered me with [i]* Advertised performance is based on maximum theoretical interface values from respective Chipset vendors or organization who defined the interface specification. Actual performance may vary by system configuration.[/i] which is what they state in their page down below.
But they failed to explain how a configuration of 2 different pc that tested the card can not be enough.One of the computers is the one at the local store where i returned the card,so i don't know the specs of that one.They just confirmed that the card was not running okay to them either.
The other one is my own H97,i7 4790,16Gb DDR3 1600,2xSamsung EVO 850 250GB,Corsair h100i,NZXT s340,CoolerMaster 650 80+ ..pc tested and running a 280X vapor X and a 390 Gaming msi at their max.I even got the 280x to run from 1100/1500 to 1200/1650 stable.

Yet the Gigabyte insists that those configurations are not enough..This is a joke..Tried every possible version of Guru and Catalyst,updated bios,even tried a clear install o windows on my second drive and the card throttles after 55C..!!!!!!
Really disappointed by this card.I know other run it at 1100 stable and the one i got can't even hold 990.

i will now post some links of many others having same problem,that gigabyte refuses to see

shame on these guys blaming our hardware for bad products

It's not really about that ~30Mhz less speed, the G1 is fast enough anyway, but the G1 is $40 bux dearer, here in OZ, than a stock R9 380.

On the other hand the G1 is quite a hotplate inside the case - fans only spin up at 54+ Celsius hence the card is pretty hot/warm all the time and that may add to the early throttling problem. I had to increase case's exhaust fan RPM to get the excess heat out just from this card. 

[Albi Losha]

yup the card runs really hot.No amount of fan control will change that.i've set mine at 80% fan speed and the temperature never went below 48.Ridiculous.!! my 280X vapor x run idle at 35 during summer and 28 during winter.never buying these crap zero fan technology cards ever again.Also never buying from gigabyte anything

Same problem here, have to raise power limit to 20% to avoid throttle. if you have temp problems at idle you can set the fan speed to 40% (keeps the temp under 40º without noise) with msi afterburner.
