In order to overclock the CPU with the MSI K8N Diamond, we changed the multiplier value to x8, so as not to have any problems with the memory clocks. We also increased the CPU voltage to 1.632v to increase stability. We had no problems pushing our AMD 3500+ (NewCastle) as high as 2500MHz. We then started increasing the multiplier and decreasing HTT.
After several tests, we could set the CPU core speed at 2750MHz, but we had several problems at high CPU loads. We were happy to see that the system was stable at 2700.8MHz.
As you can see, the MSI K8N Diamond board gives you a lot of room for overclocking, and PC enthusiasts will surely be happy about this. We should also note that during overclocking, the northbridge temperature was the same as before overclocking.
