You can't mix them up since their voltages are different. DDR works at 2.5V while DDR2 is fed by 1.8V.

915P-A v1.1/v1.2 不支持 Intel P4 Extreme CPU.  915P-A v1.2A 不支持 Intel P4 3.4Ghz Extreme CPU.

请升级客制化BIOS来解决 "Warning" 警告问题。

请使用040913S BIOS。

915P-A可以支持NCQ(Native Command Queuing) SATA硬盘.

The 915P-A V1.2A MB South Bridge is ICH6 that only supported UDMA5 (ATA100) for IDE device. In the CMOS Setup menu, the BIOS detects SATA HDD to IDE HDD UDMA6 mode, but in real mode (Post screen / Windows XP), it’s UDMA5 due to ICH6 supported Mode. The PIO, DMA and UDMA concepts are exclusively for IDE ATA/TAPI drives. These terms do not apply for Serial ATA drives. The fastest ATA mode is UDMA 6 (133 MB/s) while Serial ATA technology can transfer data up to 150 MB/s. Operating systems and other applications may recognize Serial ATA drives as UDMA5. However, this does not reflect the correct transfer rate of your drive. From Sandra 2005 test result, you can find the SATA HDD could be recognized to UDMA6 mode, but the real mode is UDMA5. Actually, UDMA5/6 and SATA model performance is the same when we use the HDD performance test utility to test it (Sandra 2005 or something else). We also found all the other brands M/B in the market that has the same technology.

TM1 is the function that reduced the CPU duty cycle (internal clock) if CPU reaches the specific temperature (depends on CPU).
TM2 is reduce CPU voltage and clock (external clock) if the CPU reaches specific temperature (depends on CPU).

MaxCPU ID Value Limit option is for Prescott CPU that could not install WinNT 4.0 issue. If you need to Install Windows NT 4.0 w/ Prescott CPU, you need to enable this option.

因915P-A V1.2在硬件上没有定义+12V电压，所以用Sandra2005软件侦测到的值是不正确的.
