R9 290X Owners Thread

jomama22 said:
Hey guys

I have tested 5 of my 6 (7th on the way) 290xs under water.

With the asus.rom bios maxed voltage (actuall voltage is <1.299v under load) i am seeing an average of 1230-1270 game stable clocks, with memory topping 1725 (6900 effective) but average landing @1600-1700.

Ill have a whole breakdown to come.

Using the pt3.rom bios, i tried feeding upwards of 1.42v (actual, setting is 1.375 or so) on these chips. On water, it depends on the chip whether it will take those volts or not. Most will take up to 1.375 (@40*c under load) before just crapping out (no matter the clocks, just fails). Iv had one lucky chip that would handle up and over 1.4v, this is also the highest asic i have (77.2%).

This lucky chip was able to go as high as 1340/1600 in valley, tuned a bit for a better score with 1320/1700 = 82.1 fps
edit: This is the right one
This chip was also good for 1315/1500 in fse, dont want to be sandbagging myself though ;). cpu is @ 4.7 here, so dont focus on the overall, 5.1 is being saved for later. GFX: 6600

Wow :eek: Get that posted in the benchmark threads.

always nice with some comparison.
I take 1250mhz anyday

What happened at the 5 fps mark? That seems scarily low.

Thracks, really?

The thing throttles at 95c~ you get the best performance by keeping it under that tempriture because it down clocks at anything over that.

If it runs at 900Mhz with temps of 95c then its not going to get to 1Ghz, put a better cooler on it and it will run 900Mhz at 80c, maybe 1100Mhz at 95c.

Look, its a great GPU, the green crowed said you couldn't do it, they said you couldn't make a GPU to match a Titan because it would be to big and to power hungry.
What you made was a Titan beating GPU thats actually smaller, no one saw that coming and its a big fat #### you to your critics.

But why, why oh why did you then not quite go far enough and give it the cooler it deserves and frankly needs? blower type coolers are not very efficient in cooling the actual chip, and the one you put on this is just a silly inadequate little block of aluminium, its the same thing as the ref- 7970.

Why did you not give it the 7990's cooler, it would have had a higher delta giving it more voltage and clocking room to reach 95c, end result: even higher performance.

i have never seen my r9 290x actually get to 1000mhz on the GPU...usually sits around 700mhz even at full load in BF4. Humbug is right, but that is nothing that can't be solved by a third party cooler to unleash it's potential.

i am on uber mode, but perhaps if I give it a little more fan speed I can reach 1k mhz before getting another cooler

Turn up your fan speeds and 1000mhz should be easy.

Mine have no problem running overclocked @1200mhz.

You tried any games yet kaaps with the card/s at 1200? what's the voltage your putting through them?

I had a quick play yesterday @1200/6500 but lasted around 10mins before i got a CTD with a direct x error.

May have been my memory though due to the lack of voltage control in Gpu Tweak.

How are you finding the card so far Mr K?

I have only used it for benching but I really like them. I think I will like them even more when I watercool them though.

I think using them for gaming will be a bit like the benchmarks, there are some things the 290X will do well and some things the NVidia cards will do well.

I did try some 3 way CF the other day but my poor 1200watt Corsair PSU was not up to the job. I will be using two 1200watt PSUs in a 900D case in the finished setup. Anyone buying these cards and overclocking should invest in a very sturdy PSU as these cards can use a lot of power.
