Foxconn N570SM2AA BIOS
We've highlighted the important BIOS adjustments possible with the Foxconn N570SM2AA motherboard in the table below.| Feature | Adjustments possible |
|---|---|
| HT Reference Clock (CPU-SPP) | 200-450MHz (1MHz increments) |
| CPU FID | x9-CPU MAX. FID (x1 increments) |
| PCIe Clock | 100-145MHz (1MHz increments) |
| HT Multiplier (CPU-SPP) | 1-5x (x1 increments) |
| Memory clocks | 400/533/667/800MHz |
| CPU Core voltage offset | CPU default to 0.200V (0.025v increments) |
| Memory VDIMM | -0.150 to +0.600V (0.05V increments) |
| MCP voltage | -0.120V to +0.200v (0.04v increments) |
| HT Voltage | -0.09V to +0.360v (0.03v increments) |
The voltage ranges are reasonable for an nForce 570 SLI motherboard but we had significant issues with enabling certain settings when overclocking. For example, we couldn't set the CPU multiplier to below x9 and CAS latency and command rate were fixed.
DRAM voltages were set such that they were higher than the expected figure, meaning +0.2V resulted in a +0.4V setting. Further, various voltage lines could only be specified with settings shown above, meaning that specific voltages - such as 2.125V for the RAM - couldn't be manually inputted.
Here's a few shots of the BIOS itself, which was updated to the P30 release before testing.
