I've just been trying some overclocking using Motherboard Intelligent Tweaker (M.I.T) in BIOS and have encountered some strange things. I have managed to increase the CPU multiplier and Vcore successfully.
I have tried to change the intergrated memory controller(CPU-northbridge) settings. I changed its multiplier from auto to 11. That should give it a frequency of 2200Mhz. I saved to CMOS and it restarted no problem there.
When I got into windows CPU-Z, AMD Powermonitor and CPU Brain identifier all registered it at the default frequency 2000Mhz instead of the expected 2200Mhz. When I changed the intergrated memory controller voltage in the BIOS it registered correctly in AMD powermonitor.
I also wanted to increase the voltage of my RAM in order for it to run at its EPP timings of 4-4-4-12. When set to auto it gives 1.8V and registers as 1.856V in the PC Health screen. I increased the RAM voltage by 0.250V. Next to DDR2 Voltage control it changed to show 2.10. I hit F10 to save to CMOS and it restarted no problem. However when I go back into BIOS and look at the PC Health screen it is still showing 1.856v. Even though on the M.I.T screen voltage control is still showing and increase of 0.25v equalling 2.10v.
When I boot to Windows Everest sensor shows a Vdimm of 1.86V. I don't understand this at all. I disabled Auto Xpress to see if that would make any difference and it didn't. Also when in Auto Xpress EPP Mode and EPP Voltage control are never selectable. I have no idea why.
Can anyone please shed any light on the above? I am clueless.
Any other weird quirks of this motherboard that I should be aware of??
Thanks.
