Help needed: Intel i7 870 overclocking
Hello everyone,
I have two questions regarding overclocking my CPU.
First, I’m unsure if I can increase the FSB speed to 200mhz or higher and reduce the multiplier.
Second, my CPU Z indicates I’m using 802.5MHz RAM, but I actually have 3 1600MHz RAM modules (2x2GB and 1x4GB). After enabling XMP in BIOS, I set the DRAM frequency to 1600MHz, but nothing changed in the CPU Z or other benchmark tools.
My hardware details are:
CPU: Intel i7 870 2.9GHz
MB: Asus P7P55D-E LX
RAM: 2x2GB XMS3 1600Corsair + 1x4GB Apacer 1600
GPU: 950 GTX
PSU: 580watt
I recently installed a water cooling solution for the CPU.

This video helped me a lot. I used the same motherboard and CPU as you did, achieving a stable 4.0ghz, but I removed it because the temperatures were too high. My case is in a corner under my desk with poor airflow, so I’m not keeping it running unless conditions improve. The CPU stayed within normal ranges, but the motherboard overheated quickly. Be cautious with that component. The CPU turbo boosts to 3.6ghz, which led me to find a stable OC at 3.7 and gradually increase it.
Regarding RAM, it’s DDR, so double the reported frequency your system shows. A 1600mhz reading appears as 800—no cause for concern there.

However, I removed it because the temperatures were too high and my setup is in a corner under my desk with poor airflow. Until then, I won’t keep it running. The CPU stayed within normal temps, but the motherboard got very hot. Be cautious with that. The CPU turbo boosts to 3.6ghz, so I found a stable OC at 3.7 and increased it gradually.
