BIOS

RD580 is a tweaker's haven, the reference BIOS images offering all manner of adjustable parameters designed to let you get the most out of your CrossFire Xpress 3200 system.

Here's the adjustment ranges you get.

Setting Range
HT Reference Clock 100-400MHz, 1MHz steps
CPU FID x4-CPU FIDmax, x1 steps
PEG Slots 100-200, 1MHz steps
HT Multiplier 1-5X in 1x steps
Memory Frequency 400/500/667/800MHz
CPU Voltage 25 levels, depending on base VID
e.g. VIDbase = 1.30V, level 1 = 1.804V, 25 = 0.604V, 11 = 1.280V
Memory Voltage 1.541-2.804V in 0.05V steps for Vdimm
0.807-1.149 in 0.014V steps for Vtt
HT CPU-RD580 Voltage
RD580 IC Voltage
SB600 IC Voltage
PCIe bus Voltage
1.143/1.201/1.260/1.299/1.348/1.406/1.455/1.504V
Nominal = 1.201V





The BIOS is probably the most tweakable we've ever seen, in terms of available adjustable parameters.
