Unable to read XFX 7950 Temps

[J-Teck]

Hi All,

 

I’m running the 7950 and wanted to monitor the temps just to make sure the case is circulating properly, but for some reason it doesn’t show in the control panel, I’m using Driver 91.33 and also have coolbits installed using the A1 option. I also installed MBM5 per instructions using nVidia driver 7.22.

 

Any suggestion would be appreciated.

Why are you using A1... are you after the additional SLI frame rendering methods and the clocks page? If so use 1A, not A1. In addition, I can't see my second core temperature until I switch to "classic mode".

Thanks Blaise, I must have fat-fingered it, looks great now core 1 reports 57C and core 2 67C, wow I guess being sandwiched like that I’d hot too. I guess this is alright for now but I think I should wait the water cooler for the 7950 come out.

[Blaise]

There should be w/c blocks for the 7950's soon... check this link out (looks kind 'a sweet).

[J-Teck]

Yes, I'm waiting on that w/c block and also waiting for the Thermaltake Mozart TX case, looks like alot can be done with this case, here's the link

Hi All,

I don't recomend using the 91.33 Beta drivers... people have reported a lot of problems with it.

 

I am using the 91.31 and I can read both GPU's temps on my G15 keyboard with the MBM5 applet.

 

Waterblocks for the 7950GX2 already exist, by Innovatek... but the only dealer they have in this continent (www.highspeedpc.com) didn't had them last time I checked. IMO watercooling this thing is MANDATORY.

Thanks Sorrento, I really haven’t seen any problems using the 91.33 drivers, I guess I’m one of the luck ones, I’ve search for problem with these divers and haven’t found anything so far.

 

What temps are your GPU cores running?

[Blaise]

Danger Den is in the process of testing out a new cooler for the 7950 (click here to view it) but no word on when (or if) they'll release it.

 

On the issue of temperature reading - I added Swiftech water blocks to my 7900GT's (and modded 'em to 1.4 volt) over the weekend. As I still wanted to use my PC through the process, I reinstalled on of my 7800GTX cards. When I finished playing around with my 7900GT's, I popped them back in and let Windows sort out the driver (91.31) by itself. Now I haven't got the temperature page in the nVidia applet BUT MBM5 can still read them (my G15 is happily showing both core temperatures - 34°C a piece... sweet). I recollect this happening once before where I had to uninstalled the driver and reinstall it to rectify the problem. It appears the the driver gets confused and simply drops the page

What temps are your GPU cores running?

At idle GPU-1 runs at 48° C and GPU-2 runs at 56° C, while playing HL2 Episode 1 (which is the hottest game I have seen for video) the gpu's run at 68/72° C... once with out the A/C on and 30° C room temperature I saw 72/78° C.

 

I need watercooling... checking the link posted by Blaise right now. Innovatek already made one and they are already selling it in Europe; www.highspeedpc.com doesn't have them yet... hopefully either Dangerden or Highspeedpc will have one soon.

 

/Edit

 

Hmm, the Innovatek looks better than the Dangerden... BUT, the Dangerden has bigger fittings, so waterflow won't be hurt too much; Innovatek's has 1/4" fittings. It is going to be available at highspeedpc.com in august:

I will wait for the Dangerden, mainly because I already tried Innovatek's and I want to see the competition

[Blaise]

Yeah, the Danger Den looks like to be at least ½" (yeah, I'm old enough that as an Aussie, I'm more conversant with imperial than metric;)). Mine whole system is ⅜" but I haven't noticed any problems so far but have enjoyed seeing a ~10°C drop in temperature (since dunking the GPU's toes into the water) and little or no increase to the CPU (compared to no GPU's in the loop) . ¼" seems a bit small but I noticed my reservoir (a Thermaltake Aquabay M3) uses ¼" on the inlet and outlet barbs.

 

My loop is: Reservoir→Pump→Radiator→CPU→GPU-1→GPU-2→Reservoir.

[Sorrento]

it all depends on the watercooling system itself, and how much heat is generated... in other words: how much overclock.

 

I had a watercooling loop that consisted on the Laing D5 waterpump, the DD TDX block on top of the Opteron 175 @ 2.75 ghz and A TON OF VOLTAGE, then the two Innovatek NV40's cooling each 6800GT @ 450/1190 mhz (A TON OF OVERCLOCK, which generate more heat than any 7800 card), then the BIX2 radiator and REPEAT. The two Innovatek NV40's were in parallel to each other with two Y connectors to join them to the main loop, each was 1/4" fittings like all Innovatek products and the whole system consist in 3/8" with 1/2" on the pump intake from the return loops (Swiftech no/reservoir thingy). Now that I don't have the two 6800GT's the CPU dropped 1° C, maybe.

 

I think my system was a little bit restricted by the two Innovatek's, even in Parallel... a single one would totall restrict the flow... thats why I was thinking about using a clear tube in parallel to the video waterblock... but I guess the Dangerden is a better option right now.

[J-Teck]

Great, the Innovatek looks great but the ¼ fitting versus DD ½, the less restricted flow the better chances of keeping the GPU’s cool, IMO. When the time is right I would like go the quad SLI route, but looking at just the 1 7950 in the top PCIe slot water cooling the NF4 chip would near to impossible getting a water block underneath these cards. Have you guys looked at other solutions for the NF4 chip cooling, if you go quad configuration?
