| Possible Memory Configration | ||
|---|---|---|
| FSB1066 (266 MHz) | 1:XX | FSB800 (200 MHz) |
| DDR2-533 | 1.00 | DDR2-533 |
| DDR2-667 | 1.25 | DDR2-667 |
| DDR2-800 | 1.33 | DDR2-800 |

Intel offers comprehensive support for manual memory timing optimization. It is also possible to increase the memory voltage up to 2.2 V.

Intel's D975XBX is the only motherboard in this roundup that reads and displays SPD information.

Although it exceeds the memory specification for the Intel 975X chipset, this motherboard supports DDR2-800. We found the DDR2-333 setting to be pretty useless, though.

We could overclock the Pentium Extreme Edition 965 up to 4.26 GHz.
| Bios Voltage Settings | |
|---|---|
| FSB frequency | 133/200/266/333 MHz (+1%-30%) |
| CPU Core voltage | 1.2750 - 1.600 V |
| Memory voltage | 1.85 - 2.20 V |
| FSB Signal voltage | 1.271 - 1.395 V |
| Northbridge voltage | 1.525 - 1.725 V |

It is possible to increase the Northbridge and FSB voltages, as well as to alter all clock speeds.
