To overclock today, we used the dedicated overclocking tools within Catalyst Control Center.
We increased the fan speeds to 60% to help a little with cooling performance. Noise levels are still tolerable at these settings. Pushing power limits higher didn't seem to have a positive effect on the final overclock.
We managed to overclock the core from 1,000mhz to 1,110mhz, which translates into a 11 percent overclock. The memory didn't exhibit substantial headroom, peaking at 1,365mhz, or 5%.
Increasing the power limit past 40% didn't improve the overclocking results.
The Sapphire R9 290 Tri-X scores 16,214 points at the manually overclocked speeds. This places it around 500 points behind the reference clocked Palit GTX780Ti Jetstream. An excellent result.
Of course the first AIB custom cooler WOULD be on a 290 non-x…my patience runs ever thinner.
Happy about the thermals. Not happy about the OC potential though. I though it could hit 1.2GHz.
No voltage tweaking? Cmon Kitguru, we wanna see more speed!
Did you increase voltage with that overclock?
Once we took the power limit to +40% (as shown in the screenshot) we didn’t find any improvements above this point. Not with this sample anyway. It can vary from card to card.
So the difference between the reference and the 100£ more toxic version is 1fps in games ? legit.
what power suply that graphic card need? (sorry for my bad englando)
The problem with the AMD cards is that they are being used for mining. Which has made the cards hard to find, and any that are for sale are at some insane jackrd up price well over the retail price. This is going to hurt AMD in the long run, as people will justto nvidia for those very reasons. AMD needs to block the mining ability, if they want to survive as a gaming card.
For reviewer:
Please, can you post a maximum VRM1 and VRM2 temperature in load from GPU-Z?
Thanks.
