According to SweClockers custom Radeon R9 290X graphics cards will not be available sooner than the end of fourth quarter of this year.

Manufacturers usually need four to six weeks to deliver custom cards to the market. For that reason SweClockers assume that custom models can even be delayed till December (sounds too dramatic though). According to their sources AMD has not yet delivered enough Hawaii GPUs units to AIBs so they are not prepared for mass production yet. That said, if you were going to purchase the R9 290X, you have two options: wait for better coolers or buy a cheapest reference model you can find and install aftermarket cooler on your own. Some etailers, like OCUK, already offer custom solutions (pictures above).ComputerBase confirmed that Prolimatech MK-26 and Arctic?s Accelero Xtreme III and Accelero Hybrid already support R9 290X, so if you are really desperate for lower temperatures and quieter operation this is probably the best way to go.

This chip is hot!!! custom cooler should be better

[zalbard]

Just in time for GTX 780 Ti it seems.

I'm curious to see what kinds of impacts this has on the overclocking thermal issues. From what I understand, the 290X doesn't really maintain "stable" overclocks because of TDP and power contraints - but if a watercooled custom card could possibly maintain a 1500 MHz core clock then I think AMD should officially be given the performance crown

First results don't seem to go much further than 1200 Mhz... In fact, it appears that 1500 Mhz is barely possible even under LN2.

I'm guessing that it's a VRM issue then. Think about it, if you remove heat from the equation then the card just isn't getting enough power. That's something that an aftermarket pcb could rectify.

[dasa]

with some chips extra power just makes no difference to clock speed
still if these things can do a solid 1200mhz on water fairly consistently id say thats a decent oc considering how low they drop on air as they heat up

Come on. They haven't even hit that much on ln2 yet and this is with some modding to the cards as the 4 + 1 to 4 + 1 +1 seems to indicate. Even with water, they are maybe getting to just a little bit over 1200. There is absolutely no evidence that this thing can clock higher than gtx 780(only the opposite) and even that can't reach 1500 even with water. When you added the maintain part its, I think you have an absolute impossibility.

Nvidia only picked up an extra 100mhz maybe from having better VRM(and better cooling) and when talking about keplar vs GCN this generation, Keplar has been able to reach high absolute clocks.

Titan was overclocking at launch at around 1733mhz with Ln2 back in February. The highest I have see a 290x is 1500mhz with ln2, so 1500mhz stable on ln2 is a fantasy with water.

We might as well say that gtx 780 ti can overclock to 1600mhz after a respin(which typically brings higher clocks and yields) because some gtx 780 can reach 1400 semi stable with water. And this has more evidence than a 1500mhz 290x fantasy on water. And I say both are impossible.

Remove heat from the equation and gk110 hits the same clocks as its smaller brethren.

Yes, Kepler scores were actually with added/modded PWMs from the getgo.
Hawaii's 1400mhz is with stock PWMs...

Edit- 2mins of research, Titan was hitting <1.4ghz on stock PWMs.
And depending on who was OCing the card, some of the hardmodded PWMs were doing ~1.4ghz.

Noticed I said gtx 780 and not titan. Higher end gtx 780's are reaching near 1,400 on air like the gtx 780 classified. Maybe not quite stable but on air.

And the cards are modded currently to reach 1500mhz with LN2.

He doesn't describe everything as he likely wants to keep his mods secrets but there are definitely some hard mods there. Maybe not PWM, maybe VRM. As he doesn't describe them, who knows. But considering the talent of Smoke and Nick Shih, I would expect some mods.

This doesn't change that we both know 1500mhz on water is unlikely, particularly stable on water. If you didn't know, I was demonstrating overextending a guess based on current information on what current cards can do. Hence the ridiculous over optimistic assumption. There is nothing to indicate that 290x can reach stable water clocks of 1500 as there is nothing to indicate, we can reach 1600mhz on gtx titan on water. Both are gigantic optimistics leaps of faith based on limited information.

So you go from saying 1400mhz on air to not even 1500mhz on water?
Again, those are beefed up PWMs, you might want to wait and see what 290x can do because you are obviously going to be surprised.

I also notice you said Kepler... You also specifically mentioned Titan... so nice try.

Edit- And no, that 290x was not modded the same way as the Titan/GTX780s were with an extra PCB for more/cleaner power circuitry.

I mentioned both titan and gtx 780 for two different reason. I mentioned titan in the first place to show Titan was overclocking much better from the very beginning compared to 290x.

I mentioned the gtx 780 to demonstrate a point of when you take too many leaps of positive faith to make a overly optimistic conclusion. I.e Take a best case scenario of the gtx 780(which clock the highest of the gk110 series) clocking such and and add a respin and all of a sudden we have a 1600mhz water stable gtx 780 ti . I already said I don't believe this and is a fantasy. None the less considering we have seen air gtx 780 classifieds touch 1400mhz in benches and gtx 780 ti seems to be based on a respin, I could see that reaching 1600mhz on water easier than 1500mhz on water when it is taking master overclockers using ln2 to reach these clocks. These guys know how to do the mods(Nick Shih, used to be number 1 in the world) and do whatever they can to obtain the best scores, if they are having a hard time getting past 1500mhz maybe its with the silicon itself as they have already done mods.

The reason I mentioned 1400 on air is because you were mentioning hard modded cards were necessary to get past 1400mhz.

Do you truly believe that with waterblocks and upgraded PCB, that we are going to see stable watercooled 290x at 1500mhz stable?

Stable is what completely wrecks the possibility.

Do you think Titans needs hard mods to bench at 1400+. Just a quick look on Hwbot and you will see simply watercooled with zero mods Titans can reach basically 1400. So with ln2, I am pretty sure Titan you can get past well over 1400mhz.

[kuroikenshi]

all this is good info but lets consider the following:

1) the current world record is held by a quad 290x setup
2) until further notice, the current world record is still held by a quad 290x setup


lets also consider:

1) when 780Ti gets the next world record I will reconsider.


world records are actually a good way to see a chip's true potential, a world record def counts are true potential.

Looking forward to custom cooled R9 290x, everytime when AMD/ATI releases a new card their top tier card always run hot on that stupid stock cooler, and not to mention the noise. I always buy a non reference card now.
