Getting 20% Extra Out Of the MSI R4830 for Free

If you're considering the MSI Radeon R4830 videocard it's almost a given that you're planning to overclock it. The card has a good degree of headroom in this regard, so not overclocking is kind of a waste. PCSTATS had a very successful time pushing the R4830-T2D512-OC beyond its 585MHz core / 900MHz memory speed settings, but not at first.....

For some reason AMD's Catalyst Control Center did not respond to our attempts to overclock the MSI R4830 videocard at all. We could change the clock speed sliders, but after hitting the 'apply' button clock speeds just reset to default values (585MHz GPU / 900MHz memory).

Furthermore, AMD's Auto-Tune function would cycle up from 585MHz Core speed to about 630MHz, but at each increment of the test program it oddly reset the figures to "0." Given the positive commentary we've seen around the web for the ease of overclocking Radeon HD 4830s, we can only assume there was some issue between ATI Catalyst Control Center communicating with this particular videocard.

All was not lost however! PCSTATS turned to AMD GPU Clock Tool v0.9.8 and the overclocking results started flowing!

Overclocking Results:
stock overclocked
gpu (core) speed: 585 mhz 730 mhz
memory speed: (900) 1800 mhz ddr (1100) 2200 mhz ddr
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

The MSI R4830-T2D512-OC videocard ships with its R770LE GPU running at a default clock speed of 585MHz. The 512MB of GDDR3 memory runs at a healthy 900Mhz (1800MHz DDR).

Overclocking was done this time through AMD GPU Clock Tool V0.8.9 because ATI Catalyst Control Center wasn't working. PCSTATS started with the GPU first, pausing to test the results with a quick 3D benchmark to ensure stability before continuing onward. We take note of any stability problems or the appearance of artifacts, and then list the maximum stable and artifact-free overclocked speed the video card can attain. Obviously, overclocking performance isn't a given, so you may see different results in your own system.

The ATI RV770LE GPU at the heart of the MSI R4830-T2D512-OC was slowly clocked up from 585MHz to 600, 625, 650... 725, 730 and finally 735MHz. However at that speed there were visible artifacts in 3DMark06, so the GPU speed was dialed back down to 730MHz.

Overclocking the 512MB of GDDR3 memory was pretty straightforward too. Starting at 900MHz, the memory overclocked easily to 1000MHz, and beyond that 1150MHz came and went.

Pushing the Samsung memory to 1150MHz was no-go however, 3DMark06 failed to run and there were artifacts on Vista's desktop. After a few minutes of fiddling around, we settled for an overclocked memory speed of 1100MHz.

Our final overclocking results for the MSI R4830-T2D512-OC videocard were a GPU speed of 730MHz and memory speed of 1100MHz, up from 585MHz GPU / 900MHz memory. Very nice indeed, that's about a 20% increase in speed for little more than a few minutes tweaking!

Prelude to Benchmarks:

The details of how the MSI R4830-T2D512-OC test system was configured for benchmarking - the specific hardware, software drivers, operating system and benchmark versions are indicated below. All benchmarks for the MSI R4830-T2D512-OC videocard were run in Windows Vista Ultimate, the reference videocards were tested in both Windows XP and Vista for the DX10 benchmarks.

PCSTATS is in the process of making the transition to a Windows Vista only test platform, so keep this in mind as you scan the benchmark results. In the second column are the general specs for the reference platforms this Radeon HD 4830 videocard is to be compared against.
