nForce2 pushed to the Max: NF7 rev 1.2 vs Epox 8r(g/d)a+

Motherboards/AMD S462 by richbastard @ 2003-03-14

Stock speeds are no option when you buy an Abit NF7-S rev 1.2 or Epox 8r(g/d)a+. Which one can obtain the highest FSB? How do they compare at extreme high speeds? Which one of these three do you have to buy to be king of the hill?

Being almost identical to the 8rga+, i have little extra to say about this. There's no 12V connector to help stabilizing the 5V line or a heatsink on the southbridge. A pitty, because they both prove to be usefull.

Note: i've put a zalman nb32 heatsink on the southbridge, this is not included in the package.

  • 1* PS/2 keyb, 1* PS/2 mouse
  • 3 audio connectors: (front, rear/line in, mic/center)
  • 4* usb 2.0
  • 1* lan
  • 2* serial
  • 1* parallel


The only difference compared to the 8rga+ are the 2 serial ports. An optical or digital spdif out would have been handy. There are pins on the motherboard to connect a spdif out bracket, but it's not included in the box.

Out of the box the 8rda+ provides an inadjustable 1.6vdd, which is too low (in most cases) to provide a stable +205mhz FSB. I've modded my old 8rda+ rev 1.0 board to provide 1.8vdd and included it in the following benchmarks.

Vdd mod with 680ohm resistor boosts 1.6 tot 1.8vdd:
