** AMD R290X NOW AVAILABLE & OVERCLOCKING REVIEW!! **

You have to laugh at AMD. Suffering extremely noisey and oven hot temps and thats just to get up there with the 780/Titan. They struggled and struggled badly. I suppose its a good thing as with the rise in heating bills this will come in handy. It's almost like the price of the card is good that its blinded everything else thats so wrong with it. Seem to remember the GTX480 getting a hell of a lot of stick on here for the very same thing. Strange that.

Definitely interested in seeing the 290 Pro's price point. I've been very close to purchasing a 770 but now it's the wait and see game.

And why are these kids crying about the 290x's power consumption? You might want to look at the difference between the 5850/5870 and the GTX480 before you compare the 290x and 780/Titan. The wattage difference (100-150+) was much more significant and particularly telling was the percentage at 30-50% more power for the 480 vs 5850/5870 compared to what, 40-60w and 18-20% versus the 780/Titan?

Fact of the matter is that none of these cards are efficient because you're still talking 350-400w of power consumption.

GTX480 is a bad example for comparison, it was not only hot, but overpriced as well. Had Nvidia priced it at no more/lower price than the 5870, it wouldn't have gotten as many stick as it did.
 
I am sure the non reference coolers will quell the stick about the card getting hot. Gibbo managed to benchmark and OC on the reference cooler, putting after market cooling on the card isn't expensive if you consider the price difference of similar performing cards from Nvidia.

I don't believe the temperature AND noise is as bad as people say. The temperature benchmarks which show 93 degrees also say that the cooler is only running at 40%. I bet this card with the stock cooler can either run cool and loud or hot and not that noisy. With the money you save by going 290x instead of titan, you could buy a custom water loop.
 
Someone needs to do a graph of £££ to 3DMark score (or FPS) over time. The best time to get a top end card is release day/week. You will get the most amount of use out of it, people are so busy banging the TITAN KILLAR!!11 drum they are forgetting just how long NVidia have had the speed crown.

The 780GTX has been out for 5 or 6 months now, launch price was what £500 - £550? That is an additional HALF A YEAR usage they have had for just £50 - £100 more. AMD have only just matched the Titan/780 performance and are charging £460 odd for it and are late to the party. You could say they have spent two years playing catch up and this is all they have to show?

Saying all that, I just ordered me a R9 290X :) It is still the best card to buy right now with oodles of potential. Coz all I have is a 6950 flashed to 6970.

780GTX owners however should be saying "welcome to the party, Y U SO L8?".
 
Gibbo when we gonna see non-ref wanna get me a windforce or toxic one of these as 95c is just lol wait until summer it's gonna throttle like crazy
 
Bit of a lurker here, registered just to ask as I know I'll get knowledgeable answers here:

Is anyone else concerned about the frame time variance (which causes the micro stuttering AMD have become known for of late)? It is still present on Crossfire solutions.

I've been holding out for a month waiting for the 290x and I am desperate to get dual or triple top end cards and start maxing out my three 1440p displays, but I am terrified that if I buy these 290x's I'll end up getting frustrated at the immersion ruining micro stuttering.

Is anyone else remotely concerned?

No.
http://www.pcper.com/reviews/Graphi...CrossFire-and-4K-Preview-Testing/Battlefield-

that before the release of the R9 290X today, there was no AMD CrossFire solution that would work correctly as we see here.

There are no dropped frames, no runt frames, etc. to be found in our first result!

You just sound bitter because right now, and for the first time in a long while AMD have a answer to everything that Nvidia have in there line up, not only that, they are cheaper, see im a fan boy, but of my wallet, and i dont care what colour i buy, as longs as i feel its best bang for your buck, i have had a fair few cards this year, 560ti, 560ti 448, 680 4GB, 7970Ghz 760 680, and now ordered a 280X TOXIC which is not far of the speed of a 780 either, great price i paid for every single one of them cards except the 760 which was dreadfull considering its the same price at the time as a 7970 or 680 when the deals was avaliable, i dont care if the titan or the 780 was better, what floats my boat if the fact that if i did need a GPU of that power, then for 429, i can get it, and that you cant argue against

I agree that AMD shoot there selfs in the foot by not designing a better cooler in order to appeal to a wider audience, but given the price it can be forgiven, plus id water cool a reference card anyways ;)
 
**UNDER-VOLTING**

Guys it seems the current drivers / BIOS have protection built in so the card won't allow you to under-volt it by any usable amount unfortunately.

Anything below 1225mv seems to trigger protection meaning it won't load to windows desktop until you do a full power off and on.

However going from 1250mv down to 1225mv has reduced temperature by 5c under-load with no ill-effect on stability at stock speeds with the card still set at +50 power with 1000Mhz core speed always.


If this protection gets removed by later drivers/BIOS the card in theory should be able to run fine around 1150-1200mv which should be good for a good 10c+ reduction in temps over stock. Seems you can get them to run pretty cool.

Infact its turning out to be quite a fun card for the tweaker/overclocker. :)

Damn I'm good.

That's 7950 boost voltage. I bet its possible to lower stock voltage and still achieve decent clocks. AMD do love to add excess voltage to low asic boost cards. What are the asics, did you check? Under 75% id bet.

I reckon 1.2v-1.225v should be ok. 1.1v sounds a bit low though for low asic.
