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.
