New to AMD - MSI HD 7970 Twin FrozR OC BE Temps

post #1 of 5
Thread Starter 
Card in question - http://www.msi.com/product/vga/R7970-TF-3GD5-OC-BE.html#/?div=Specification

For the last few years I have a series of Nvidia cards and my last card, GTX570 SOC Windforce, which was pretty heavily overlcocked would sit around about 80 degrees under load.

Today my MSI HD 7970 Twin FrozR OC BE arrived and all I've done so far is to install the latest CCC/drivers and try Heaven/Valley and play some Payday 2. In the benchmarks and in PD2 the card will hit 97 degrees which to an AMD novice like me concerned me a little.

I was advised to install MSI Afterburner 3.0.0 Beta 15 and try running Valley once more. I'd guess the ambient temp in the room is about 25 degrees and the card started at an idle temp of 40 degrees. Here's the results -



Obviously it's not as high as 97 degrees but I'm not sure if that's because the newer version of Afterburner is more accurate and/or it's simply down to the relatively high fan speed (which was quite audible).

So I guess what I'm asking is -

A, Nothing to worry about, just enjoy the card

B, I've made an obvious error somewhere

C, The cards faulty and needs to be RMA'd.

OP if its overheating you could try cleaning the die and reapplying a high quality TIM like prolimatech PK-1. setting a higher fan speed would help but it would come at a higher noise cost. if temps are hitting 90+c send it for RMA.

I've been running this same card for the past 3 weeks. When i get home tonight I'll try to remember to screen shot my msi afterburner showing it's hottest. But off the top of my head I think its around 70c with ambient temp around 26c. 90 sounds crazy high to me. Other than the little bit of coil whine this card is phenomenal, coming from oc'd 5770 in crossfire.

I posted on the official MSI forum, thinking they'd know best, but it's left me even more confused.

One of the MSI reps accused me of increasing the voltage but I've done no such thing. All I've done is install the drivers and MSI Afterburner which reports the vcore at 1256mV. I found one review online* for this exact card/SKU and their screenshot also shows 1256mV so quite why they'd accuse me increasing the voltage I'm not sure.

Since I posted yesterday things are slightly better. At 1256mV load temps are now 80c but the fans ramp up to 77% which equates to 3600rpm. If I "undervolt" the card to 1180mV temps load temps go down to a more respectable 72c but the fans still ramp up to 75% or about 3500rpm.

All the feedback I've got elsewhere and from the review I read state I should expect load temps in the mid 70's with fans at 45%**. Way less than I'm experiencing.

** - "With the fan control set to auto, the highest temperatures we saw was 71 °C. The fan hit around 45% to do it and was pretty silent"

Run the highest core clock with the lowest voltage possible. Fine tuning your card will likely yield improvements for temperature and render speed. Use your custom fan profile feature and shift the fan to 45-50% at 75-80°, I would bet you'll see equilibrium in the high 70s / low 80s. Quiet profile, respectable temps.. Likely no reason for concern. Gl thumb.gif
