This is my 1st attempt at overclocking, and I have managed to safely get to 2.6GHz on air.
However, the VCore voltage is confusing me a bit.
I read the AMD specs for this cpu here, and it's 1.3-1.35V. Not sure how correct this is, though, as it's also rated at 110W and 80A, which should make the voltage required 1.375 (W = V * A).
So, on my system without overclock, and everything set to auto, my VCore is reading 1.392V according to BIOS, CPU-Z and Speedfan (same sensor, so no surprise all are reading the same really )
Anyway, I did some tests and managed to get up to 2.643GHz 'stable' (20min test with Prime95 on both cores) using ClockGen in windows (anything beyond that failed with voltage at auto/standard). I decided to drop it back to 2.6GHz, and plan to do a 24Hr test at this speed.
However, in order to fix these settings, I have to manually set the VCore voltage due to the way the options are available in bios. Basically, this mobo has an option FID/HID change. This controls the CPU multiplier and VCore voltage. If left on auto, and I put the HTT up to 260, then the multiplier automatically drops to 8x.
So, knowing that I have to manually fix the multiplier at 10x, I need also to set the VCore.
This is where I'm a little unsure as to what to set for the VCore. I decided to set it to 1.35 (in an attempt to stay within specification for the cpu). However, the VCore still reports 1.392V in bios.
Is this just a perculiarity of the motherboard ? Or maybe the mobo is recognising that the CPU requires a minimum of 1.39V, and therefore supplies that ?
If anyone has had similar problems and would care to share their experiences, it would be appreciated.
Thx in advance
