Hawaii 290X/P Overclocking Guide

Interesting, thanks for the info. I wasn't aware of the mem/core ratios in overclocking scenarios but it could be due to the memory controller changes?
 
If every card has its own core/memory ratio, overclocking tri and quad setups would be a nightmare.

Any recommendations on how to go about finding the ratio?

In gputweak, disabling the skin will reveal the lock button (as well as other features) for voltage vs clocks. Enable the lock. As you raise the clocks, voltage will rise accordingly since they are locked together now. You can use that as a guide for starters.

Not sure how locking the voltage to the core would help me find the optimal core/memory frequency ratio for my card(s)... :whiste:
 
I'm working on overclocking my r9 290 tri x right now. It's an amazing cooler, but this card is plagued by some coil whine. It's bad when the card is ramping up and down, but stops once clocks and voltages settle into their max and min values.

Somewhat disappointing, but I'll see how far I can push it.

If you are using Trixx, what do you use for monitoring your cards?

Thats how you get the clocks man. My ridiculous ambients does help, but if i didnt know the ratio of my card i wouldnt get anywhere.

Holy f***.
Finally a Hawaii card above 1300 Mhz.
Did you have any trouble pushing voltage through the card except the heat..??

I am trying to debate if the 290x lightning is worth it.
You would think with the card in hands of users for approximately 2 weeks & unlimted voltage, we would have something more than 1200s Mhz. Sadly nothing yet.

Ive been thinking about a Lightning too, but we'll see. Also from my observations 9/10 290s and 290xs will do 1300+ given enough volts (1.4 - 1.55v in GPU Tweak) so its not actually that rare. But you need the cooling for it. My 290p (Which i just sold 🙁 ) will do 1310 in Sapphire Trixx with 200mV :awe:
 
Thanks for the guide.

Regarding drivers I still get clock throttling with any driver after 13.12 with any added voltage. Doesn't matter what power limit I set or what temps. Just confirmed it still does it with 14.3 and Trixx. For example +37mV @1150 +50% power limit the clocks vary between 1100-1150. I have tried every beta driver, forcing power limit in Overdrive and using MSIAB and Trixx. 13.12 same settings 1150 constant.

This is just me reporting what occurs with my card (Tri-X R9 290) not complaining about the guide. 🙂

What you using to load the card?
 
I can only get 1150 with +50mv on the core. I'm not sure how far I can push voltage on hawaii. Anyone know? Is it still around 1.25 like Tahiti?

Who told you 1.25 is the most you can push Tahiti? And ... sigh. Dude, didnt you read the guide before i removed it? This is why i removed it, people dont read it and they still ask questions.

From my guide:
For all in benching you have no choice but to use modded GPU Tweak that allows for volts up to 2V, you'll also need to flash your bios, i suggest the PT1 bios for the 290X and PT1T for the 290P. Ill link other relevant guides and download links for bioses and GPU Tweak on the bottom.

Max volts i would use under water for benching with GPU Tweak is 1.55v, it'll drop to 1.47-1.5v or so depending on the card. For air you should just use Trixx and go all in 200mV, wont kill your card for quick runs, just make sure your fan is running 100% and that you open your sidepanel so it can breathe properly.

I'm not interested in quick suicide runs, but 24/7 stable clocks. Going plus 200mv probably isn't smart for that even with a tri-x cooler.
