triple 1080s . . . yah, 2 290Xs would be ideal. that is, if you can handle the pains of eyeinfinity combined with multi-gpus. looks like you are not the type who whines a lot.

It is a good pick by all means, case internal temperatures are improved with use of the reference cooler. Else, you might even benefit from a backplate.
You should undervolt to curb the 'Poole-Frenkel Effect'. I've read users sustain 1 GHz at 1.03v, so the extra +0.17v is needless and even challenging for the cooling performance. The gpu won't begin throttling below 80c, so that would give you extra leeway to avoid any performance degradation while maintaining a suitable fan profile of your preference(quiet profile at 94c will fluctuate, afaik).
If it weren't for high temperatures, you could replicate the success of 390X which is right up there with 980Ti in Hitman:Absolution, even running at 50 watts lesser power. 1200/1525 operation is also cooler than said temperature limits. Thus, low leakage profiling is sacrificing much of Hawaii's performance due to temperature degradation. Though at the time, MSI Gaming series was unrealized.

valley benchmark 58.9

post #44 of 64

i also monitored temps and fan speed during 290x valley benchmark. 290x set to QUIET mode

Temps climbed to 94 but fan speed never went over 43% (2200 rpm) so the fan was quiet the whole time

I guess 95 C is safe, as long as I'm happy with the fan noise at that temperature (there is no fan noise at 95 C so yes, I'm happy) I'm not going to worry about the seemingly high 95 C

sources for 95 C being safe:

"Do not be alarmed at the 95c temperatures on the R9 290X. Remember, the video card is designed to run with the GPU that hot. It may be a shock to us, expecting much lower temperatures, but 95c really is OK for the card and GPU."

"AMD have been very keen to point out that the 95ºC operating temperature of the Hawaii GPU is perfectly normal, and presents no tangible risk to the working life of the chip."

"Under load the card runs at 95C, which is not only hot enough to burn you but also alarmingly close to what is generally considered the limit at which silicon can operate - around 100-105C. In comparison this card’s main rival, the Nvidia GeForce GTX 780, runs at around 80C when under load.

However, AMD insists this is by design and not a problem. "

"The 95C maximum operating temperature that most 28nm devices operate under is well understood by engineering teams, along with the impact to longevity, power consumption, and clockspeeds when operating both far from it and near it. In other words, there’s nothing inherently wrong with letting an ASIC go up to 95C so long as it’s appropriately planned for. And this, more than anything else, is what has changed for 290X and Hawaii."

"As noted in our explanation of the new mechanisms included in PowerTune on the 290 Series, we have designed the 290 Series to operate at a steady state of 95C. By running at 95C, we are both maximizing the performance and minimizing the acoustics of the product. We do this by increasing clocks/voltages and/or reducing the fan speed until the GPU runs at the temperature target. By having the GPU target at lower temperature, you sacrifice either performance or acoustics.

Some of you have expressed concern over the GPU running at 95C. Be assured, that 95C is a perfectly safe temperature at which the GPU can operate for its entire life. There is no technical reason to reduce the target temperature below 95C. However, like all aspects of PowerTune, this is completely within the control of the end user. If you would rather have you GPU operate at a lower temperature, such as 85C or 73C, we strongly encourage you to customize it to your preference and write about it in your review. This is, after all, the reason that we design products with this level of flexibility."

Just to see if fan speed made a difference (some reviews claim it does) I set the fan to 60% and ran the tomb raider demo again

60% is what I consider WAY TOO LOUD. If it ever sounded like this during gameplay I would not use this video card and get a different model. Last time I had a card that loud was.... i don't even remember, tnt2? x1900? 5770? I don't know, I have had stock cards get that loud before, but that was a long time ago, they shouldn't be that loud anymore.

Anyway, Tomb Raider at 60% fan was 47 fps vs 46.4 with the stock profile that was quiet. That's a 1% difference and could be due to anything, might not have anything to do with fan speed. So I'm sticking with the slower fan speed that's quiet

i whine all the time biggrin.gif

Use to be a loved tinkering with PCs. Now I just want them to work with minimum fuss. I don't know why, probably because it went from a hobby and fun to a necessity and work tongue.gif That's probably why I have never tried crossfire. That and it never made financial sense, it was usually cheaper to buy new and sell the old then to buy a second old.

For example I could have bought a second 280x for $150+ and crossfired it and got much better scores than this single 290x. But I don't need it for the resolutions I'm running, so it's cheaper to buy the 290x for $225 and sell the old 280x for $150+, spending <$75 instead of $150 and saving me all that crossfire hassle and the pointlessness of running 60+ fps in every game instead of just 40+ fps thumb.gif

I set the fan speed to 100% and it's the loudest I've ever heard a fan be. NOTE: There should NEVER be any normal gaming circumstances where a 290x gpu fan is at 100%. The software controlling it will never allow it to get to 100% because it is never necessary for the fan to do 100% even if the GPU is pegged at 100% for hours.

Best comparison is a leaf blower

I'm putting a video together with sound from all the fan speeds, from 20% to 100%, complete with what it sounds like while Valley benchmark is running. It was recorded less than 3 inches from the GPU with a iPhone 6 Plus so it's absolutely the worse case scenario of what the reference cooler sounds like.

here is the video
post #50 of 64
Yep, its either have a 200mhz throttle or have a leaf blower. It starts out fine at 1000mhz but drops off considerably when you game for a while, all of the reference 290/290X I've had ended up around 800mhz after an hour or so of gaming, and I've had a lot of them (6 290's and 4 290X's). That being said, the last two 290X's I had both went 1200+mhz with a Corsair HG10 and an H55. A 1200mhz 290X is friggin fast.
