Sapphire PURE AM2RD580 BIOS
Jumping right in.
| Feature | Adjustments possible |
|---|---|
| HT Reference Clock (CPU-SPP) | 200-440MHz (1MHz increments) |
| CPU FID | x4-CPU MAX. FID (x1 increments) |
| PCIe Clock | 100-200MHz (1MHz increments) |
| HT Multiplier (CPU-SPP) | 1-5x (x1 increments) |
| Memory clocks | 400/533/667/800MHz |
| CPU VID | 0.550V to CPU MAX (1.450V). 0.550V-0.7625V in 0.0125V increments. 0.7650V-1.450V in 0.05V increments |
| Memory VDIMM | 1.541V to 2.804V (0.05V/0.051V increments) |
| Memory VTT | 0.807V to 1.149V (0.013/0.014v increments) |
| NB and SB voltage | 1.143/1.201/1.260/ 1.299/1.348/1.406/1.455/1.504v |
| HT and PCIe Voltage | 1.143/1.201/1.260/1.299/1.348/1.406/1.455/1.504v |
The voltage and speed options are pretty good and tweakers should be able to get the most out of their system by toggling the various options. The BIOS also features a CPU VCore offset that enables a maximum voltage of 1.9V assuming a CPU VID of 1.4V
We'd like to see higher CPU VCore and options that allow you to save the BIOS configuration into a profile. You'll see why if you take a look at the level of DRAM adjustment possible.
You could be in there for a week! Even with this slew of options, there's no provision for manually selecting the DRAM command rate.
