Adjusting the clock speed of the Optiplex 745 Small Form Factor CPU
Adjusting the clock speed of the Optiplex 745 Small Form Factor CPU
Hello, I need guidance on how to downclock the Core 2 Quad Q6700 to 2.13Ghz. I want it to match my Core 2 Duo E6400 at 2.13Ghz. The Core 2 Quad is coming soon, but I'm unsure if it will work with my 275W PSU and worry about overheating. My motherboard uses the Intel Q965/Q963 chipset. Please confirm if this information is sufficient and whether the downclocking level is appropriate. Thanks for your help.
It isn't necessary to slow it down too much. You can handle a 130W QX6800 if desired. Consider using the JP911 heat pipe cooler.

The device was initially equipped with Pentium4 and PentiumD CPUs. A 3.4GHz, 130W CPU is perfectly compatible with that setup. However, the aluminum 2-core heatsink needs replacement.
Make sure to install the most recent BIOS from Dell—download it and run it from there.
William P suggests not downclocking. The system can handle a 130W QX6800 if needed, but using the JP911 heat pipe cooler is recommended. He shares a link for reference. The original model came with Pentium4 and PentiumD CPUs at 3.4GHz and 130W CPUs are typical for that setup. However, the aluminum 2-core heatsink needs replacement. Make sure to install the latest BIOS from Dell by downloading and clicking run. He apologizes for not providing more details earlier, as he wants to conserve power while planning to add a Core 2 quad q6700 and R5 240. He checked using a PSU calculator online and found the PSU reaches 276W, which is just over the limit. Reducing the CPU frequency from 2.66 to 2.13 lowered the load to 260W, safely under the threshold. Now he asks for advice on whether underclocking or adjusting the wattage with the Core 2 quad q6700 and R5 240 in the Optiplex 745 SFF is safe. Thanks.
