The Massive Cooler

As you already are aware, highend videocards generate a lot of heat, hence the huge cooler on the RX850XT-TD256E. The copper heatsink comes in direct contact with the X850 XT core while heat is drawn away from the memory on the front of the videocard via the large aluminum heatspreader.

On the back, the memory is cooled by a smaller aluminum heatspreader. The cooler mounts onto the videocard via six mount points, two around the GPU and the remaining four placed evenly around the card.

The shapely 65mm squirrel cage fan acts as an exhaust and expels hot air from the case via the adjacent PCI slot. This makes sense, since you wouldn't want that warm air circulating inside the system. The fan is temperature controlled and during PC startup it spins at 100% speed, making quite a racket.

After about three seconds it slows to normal operating speed though. We did not notice an increase in noise level during testing, even with the card overclocked - so this is not really an ideal low-noise videocard.

If you're paranoid about temperatures, the MSI RX850XT-TD256E does have an integrated thermal probe on die. Programs like RivaTuner can read and log idle/load temperatures, which is more useful than ATi's driver core temperature reader.

Overclocking the RX850XT-TD256E

Overclocking Results:
Stock Overclocked
GPU (Core) Speed: 520MHz 582MHz
Memory Speed: 1080MHz 1215MHz

If you're new to Overclocking and not sure what to do, check out these two excellent Guides for some pointers:
Overclocking the CPU and Memory
Overclocking the Videocard
By default, the core of the MSI RX850XT-TD256E is clocked at 520 MHz while memory runs along at 1.08 GHz. This is 20 MHz slower on the core and 100 MHz slower on the memory than the flagship X850 XT PE GPU.

The first thing we did was raise both core and memory to X850 XT PE speeds and we were glad to see that the RX850XT-TD256E had absolutely no problem doing this. That should save you a couple of hundred dollars for starters. :-)

Raising the core speed in 5 MHz intervals, it seemed like the RX850XT-TD256E might be able to break 600 MHz core speed barrier with stock cooling. Unfortunately we didn't quite get up that far since the core started to give us problems around the 585 MHz mark. Lowering the speed to 582 MHz seemed to stabilize things.

Next up was the memory. Starting at X850 XT PE speeds, I first topped up the memory to an even 1200 MHz. We didn't get much farther than that with the memory sadly, since anything higher than 1215 MHz caused the videocard to start showing snow in 3D and 2D modes.

Considering that the RX850XT-TD256E is clocked at 520/1080 by default, its a pretty decent overclocker.
