Umm... I dont really remember but your board doesnt have enough power or somethibg with 3+1 vrms .: overclocks are limited. Cant support enough power for higher clocks. Thats why higher end boards get 8+4/8+2.
The problem with a 3+1 power phase is that it will easily overheat and blow up, because voltage loads are focused entirely on 3-4 phases instead of 8+ phases (so what would be a fine 60*C on 8+1 would be 120+*C on 3+1... not exactly, but basically).
It's more like an issue of "you motherboard is either exploded or not exploded". My motherboard is not exploded, and I've done quite a bit of tweaking to make sure it doesn't (6 x 120mm fans on 100% speed, 1x80mm fan, heatsink on vrm's).
But yeah, id say 3.7 @ 1.5v is very good and stable 24/7 overclock. In fact its a really good result considering the board is a 770.
What difference would it make?
I'm a bit confused what you mean. I don't get how a motherboard, besides having a higher or lower fsb max value, would determine overclock stability. The only thing I see the motherboard determining is more like safety, ie you probably shouldn't try to overclock a phenom x4 on 1.55+ volts on a 3+1 power phase but there's nothing exactly stopping you from doing it.
Whereas I can't exactly run a 955 on 5ghz on air because temps and stability would both be a limiting factor.
Anyways, Mystery Temperature readings "Thrm/TMPIN0" in HWMonitor and temperature 1 in HWINFO gets up to a max of 47*C. I think it's my motherboard socket temps. If anyone else with a biostar a770e3 could talk about what the 4 temperature readings the motherboard gives out are, that'd be great (i think there's 2 socket monitors, the motherboard chipset northbridge, and some other temp i think maybe ambient or case temp). I am not sure if the coretemp reading is really accurate, i dont trust AMD core sensors, my athlon core temp was always ridiculously below ambient.
On a side note, CPU-Z says 125w TDP, but HWmonitor says 113 TDP.Edited by Belial - 11/7/12 at 9:03pm
