MSI R4830 512MB Overclock Edition Review

» Discuss this article (4)

Closer Look:

The R4830 uses the same RV770 GPU core that is found in higher end 4850 and 4870 video cards. The factory core clock is set at 585MHz which is 10MHz higher than reference 4830s. The Samsung sourced GDDR3 memory runs at 900MHz through a 256-bit interface. Since this is labeled as an "Overclock Edition" card, MSI has included sold state chokes, solid capacitors, and an advanced 4+1 power phase to hopefully improve overclockability. The R4830 has 640 shaders compared to 800 shaders found on 4850 and 4870 cards.









The video output end of the R4830 has two DVI ports and a TV-out port.t. The opposite side of the card has a single 6-pin PCI-E power port for power.



The R4830 has two connections for Crossfire bridges. This feature would allow 3 ATI cards to be used in conjunction. Also, the R4830 features MSIs 4+1 power phase. This hopes to improve power efficiency and overclockability. Memory for the R4830 is sourced from Samsung.



Temperatures are controlled by a "seaweed-blade"-style heatsink. The heatsink is made from a single piece of machined aluminum and doesn't come into direct contact with the memory chips. I believe MSI expects the fan to draw cool air over the memory.



Four screws on the back of the PCB are removed to get full access to the GPU core. In typical fashion the thermal paste has been applied heavily from the factory. At the heart of the R4830 is the popular and powerful RV770 core. The RV770 is used in ATI video cards ranging from the 4870x2, in which two RV770s are used, to the less expensive 4850.


Lets take a look at the drivers and programs MSI provides with the R4830.
