That's UEFI!

Looks like they are performing worse than my XFX cards.......that's a bummer.

I originally got a Gigabyte Windforce r9 290x and I liked the design with 3 fans.

Anyway, that card died within 5 hours of use so I sent it back and get a MSI gaming R9 290x.

The Gigabyte RMA page was down, and the technical support lady was rude, so I decided to switch brands to MSI because I have two GTX 760s that I'm extremely impressed with.

I also have a gigabyte ga-990fxa-ud3 (rev4) that is a nice MB except the BIOS is buggy. For that reason I decided to switch.

I was fine with one card, but when I added the 2nd MSI r9 290x I had the same sort of issues with the top card throttling down due to cooling.

I cut a hole in the side of the case and put in 200mm fan directly in front of the cards. That location originally had an 80mm fan.

Hot air was also begin trapped in the case to I cut two holes int he top and installed a 120mm fan in each.

The case takes 2 80mm fans in the front and 2 80mm fans in the back(for whatever that's worth), so I made sure those where all present and fresh.

The 200mm fan causes primary GPU temp to drop dramatically, however, the bottom card does actually increase 1 or 2 degrees for whatever reason.

Cheers!

Haha, yes, I'm 100% sure - it really doesn't take a college degree to mount one and I have plenty of experience over the last 15 years. MX4 is the TIM and the results are the same on open bench and with closed case - which has tons of cooling anyways. VRM and ram is cooled with the stock heatink baseplate(with the removed cooler). A guide can be found on here on OC.net for anyone interested. And the temps are very cool on vrm 1,2 - low 60C.

I'm really curious since XBIT used a S1 with the turbo module on a radeon 7770 @1.1Ghz and they were reaching 60C temps. All this makes sense, given the cooling capacity of the S1 is 120 watt and 7770 a 100watt TDP. Mind you that is less than half the heat output of a 290.

http://www.xbitlabs.com/articles/coolers/display/arctic-accelero-s1-plus-turbo-module_4.html#sect1

In all honesty, I wasn't surprised with my results. The S1 compared to a windforce cooler on my GTX 770 has less then half the cooling fin area and weights half as well and that same heatsink on a 290 is just about adequate for OC and mid 70C temps. Now, its important to note that the windforce is a 450watt cooler, the S1 is a 120watt(just check the Arctic Cooling site).

How you are achieving this is like I said, 'black magic'. You basically were able to pretty much triple the cooling capacity of the S1 wth.gif

Haha smile.gif I actually got my GPU up to 84C while playing Crysis 3. For some reason, during BF3 the GPU drained 201W max. Crysis 3 ups this to 251W. I have my temperature limit set @ 85C, and the clocks were 95% of the time at 1093 core. On rare occasions, the core clock dropped to 1047mhz but never any lower. I think that the high CFM fans compensates the lower fin area and heatpipes.. And btw, this heatsink is not suitable for mining if overclocked. I mine at 900/1250 850kh/s and core caps out at 75C, VRM1 76C and VRM2 64C.
Can you show some pics of your cooler please?

I will do a 5hr run of Unigine Heaven tomorrow, let's see what temps will there be.

Here are my VRM heatsink setups:

Aww!!!! Well, from what you wrote here it seems that powertune is working with your 85C target and it limiting the power big time - I would like to see you run a firestrike (just the regular test) and post a score. That should shed some light here.

I'm in the office at the moment. I'll post some when I get back home - apart from the stock baseplate cooler and slightly different fans its the same thing. The fans that I used have a higher CFM then yours. It seems you have a chip that doesn't leak much heat - whats your asic quality?

Settings are as followed: (CCC)
Power limit: +12%
GPU: 9,3%
Memory: 6%
Target GPU temperature: 85C

ASIC quality is 75,1%.

Heres my FS, Cloud Gate and Ice Storm results:

But tomorrow, I will test out 5h of Unigine Benchmark and i'll put the target GPU temp to 95C.

@coree: you have your vrms backwards.

vrm1 is core, vrm2 is memory.

Vrm2 doesnt need crazy cooling.

hi, why my core stays always on 1000 mhz on idle(desktop)? with drivers 14.2 Beta mad.gif
post #18240 of 43977
mine stick too.

open CCC, go to the perforamce tab, enable overdrive, click reset to default and save. You may have to do it a few times.

should fix it.
