Ati 5970 Water Chilling

[EvilClocker]

Here are results from Final Version of the Block

wow, much nicer than rev 1 DD. Great temps all around vrm & gpu, evilclocker. Got a screenie of your max oc?

[Eddy_EK]

I'd like to see water temperature on this and clocks.

Well in his screen shot of Furmark shows 849mhz for core and Memory at 1200Mhz. But if I do remember he's doing his with Dual Coolit Boreas now is that just the GFX or our you cooling all of your system with the Boreas's. If just the GFX what are you setting up the temps in the Mtec below ambient and if so what are you doing about condensation.

I also have a Coolit Boreas but set up just for my CPU and NB Core i7 920 and will have my 5970 on a GTX360 Rad.
So yeah just like Eddy Ek I would like to see water temps but more looking towards others with just using Rad, Pump, Block set up.

Iam runnng a Core I7 860 o/C to 4ghz 5970 1.165v 850mhz 1200 Ram.. Water Temps stay around 20-21C Running a Coolit system Boreas and Dual Freezone elites. All 1 Loop CPU and VIDEO

jaredpace , My card does 1000mhz on core max.. I get you a shoot today running furmark at that speed. Things heatup little more at that speed

[jaredpace]

If you think you can go higher (or even want to) AMD GPUclocktool raises cores > 1000 mhz, and Asus Smartdoctor increases Vddc to ~1.45v.

Jared,

YEah I have to use AMD GPUclocktool.. if I dont my screen flickers in 2d mode.. 1ghz on the core things heatup about 10c more on vrm maybe 1-2c on the gpu cores.. MY cooling systemup is pretty good

Hey Evil, could you run Furmark fullscreen? I tried running it at the same voltage and clocks as you and my frame rate average was about 190 (@1920x1200 Fullscreen 0xAA). Yours was 125. This would also explain why your current draw was only 40ish when mine was 60+. At 950mhz @ 1.225v my current draw is about 80 amps. I'm curious how well that block does under these situations. Also, it seems when using AA the current drops significantly.

Huge change of mind from the guy who used to screw aluminum plates on his blocks to cool VRMs

Worked just fine for GTX 285. I had great overclocking results with that EK block and it ran nice and cool.

I confirm, same story with EKWB FC-GTX285. A little bit tricky for coupling the vrm on the right side but when done, performance was great. I received today the FC-HD5970 from Slovenia, looks great, have some pics here: http://forum.hardware.fr/forum2.php?...w=0&nojs=0#bas (end of the page, french forum but international pictures and mouting instructions ) Hope the performances will be as good as with the GTX285.

Is this topic only for chilling of the 5970? Or may we also add results of watercooling of the 5970? (no chilling for me, only watercooling).

Thx

[EvilClocker]

Scaniris, Please post your Results.. I am interested in how well the EK block performs

[Scaniris]

Ok I'll do it end of this week, I have to install the waterblock and upgrade my cooling system before (and don't know if I'll choose a single or a dual loop configuration...). But I have no chiller, temp of water is @ 24,5°C average in idle mode, and maximum 30°C @ full system load (when I had the GTX285 and the i7 860 in the same loop, I don't know what will happen with HD5970 and with 1x480 + 1x240 rads).

I made some measurements with the stock cooling system of my XFX HD5970, using Stalker cop benchmark, and Furmark. I've recorded information with GPU-Z and MSI Afterburner monitor. After mounting the HD5970 waterblock, I'll make same measurements in same conditions, and compare. Without any overclocking, I want to compare stock versus water cooling solutions. So I apologize not to have Chilling unit in my system, it will be difficult to compare my results with yours because you are using cold water (I'm really interested in your system, I had a look yesterday on the CoolIT website, nice solution! )

[EvilClocker]

Make sure you do. the 5970 does but out some heat in the loop.. I am running a single loop on my rig.. The boreas is a good unit.. but not enough for a cpu and 5970.. so I am running boreas and (2) Freezone elites.. so Most of the time My Card is Chilling around 18-19C :-)

[Scaniris]

I'll create a new post to ask my questions about single or dual loop, I don't want to pollute your thread about HD5970 water cooling/chilling with another discussion not related with main subject But ok I'll post the results as soon as possible.

[Scaniris]

Hi EvilClocker,

I've put some screen shot on the HD5970 topic, but I put them also here:

Here are the temp results after 1h30 of Furmark @ 1920x1200 with MSAA @ x8.

The GPU Z screen shots show maximum temps recorded during the benchmark. The GPUZ windows up shows GPU1 info, the second window down displays GPU2 info.

BEFORE the stability test, here are the monitoring informations:


And DURING the benchmark, a screen shot of monitoring information (the Furmark was running in front of all the rest during stability testing, here it's running behind only for the screen shot, I used the Alt + tab function to switch windows)

[Scaniris]

What's strange is... that my temps are not really higher than yours, but I don't use chilling, only watercooling... coolant temp is 27,7°C after 1h30 of Furemark load... yeah some degrees, but the difference is not huge. I though it would be a bigger difference.

[EDIT] hum sorry... you have overclocked your card... so yeah my results are without overclocking, with a single loop for WC CPU + GC.
