Hello All,

I use MSI R9 270X 2G OC Edition for my gaming computer and I recently overclocked it to check on its performance. I used MSI afterburner.

Core Voltage (Stock): 1206 mV
Core Voltage (Overclocked): 1213 mV

I tried to dwell on stock voltage but unfortunately I'm not able to push my card without a minor uplift of the Vcore.

Graphics (Stock): 1080 MHz
Graphics (Overclocked): 1160 MHz
Memory (Stock): 1400 MHz
Memory (Overclocked): 1460 MHz

Other than these, the fan profile is kept in AUTO while power limit percentage is at default.

The Maximum temperature -> 76 C

I've stress tested my gpu with the help of Unigine Heaven Benchmark in which the test ran for 1 hour straight.
Request: Provided you have any comments, suggestions or constructive criticism, please reply to this thread. Thanks in beforehand.

"Using MSI Afterburner we were able to overclock the MSI Radeon R9 270X GAMING (OC Edition) even further, by increasing the Power Limit to 120%, the Boost Clock by an additional 60MHz and the memory by 150MHz. This gave us a real world Boost Clock of 1180MHz and a Memory speed of (6200MHz effective).

The additional overclock on the Core (60MHz) is not that high, but we must consider that the card already sports a factory overclock of an additional 70MHz! The memory overclock on the other hand is much more impressive with an additional 150MHz. When used in conjunction with the additional Core overclock the MSI 270X really...

Well, I was not able to reach 1180 MHz as graphics clock with 1480 MHz as memory clock because the card's temperature touched 79 and beyond which eventually throttled my card and lead to auto shutdown. It seems like the problem is in the tower. The temperature falls by 74 C only if the case is kept open for the above mentioned clocks. I think I can still push my card beyond the limit only if the case has a good airflow.

This is the tower: http://www.antecindia.co.in/product.php?id=NzA0NDA5

And how can I push the power limit to 120%? In afterburner, I can see only a maximum of 20%.

Oh, okay. So, should I keep it to 120% or will 100% be good? Now, I tried with 1170 MHz graphics and 1470 MHz memory. Artifacts appear during the test. So, can I increase the voltage? Will it increase the temperature beyond 80 and start throttling? In the current overclock settings, the temp is almost 77. That's why, I don't know if its safe to overclock further.
