Hello, I was hoping someone could offer their advice on how much power I can safely pull through my GA-EX58-UD3R (rev1.0) not to be confused with the upgraded X58A-UD3R variant. Since it was the cheapest X58 motherboard at the time I assume the VRM design is rather weak. The board was never pushed hard but its very used, a very rough guesstimate would be around 14k hours powered on with an i7 920, a quarter of those hours at high loads.
I ebay'd a $24 X5670 and everything runs fine, since the board is so old I went with a soft offset overclock of 4GHz(167 x 24) uncore is at 3507. These settings produce a score of 940 in cinebench R15. At the current vcore offset it's showing 1.184vcore during prime95 small fft and hwinfo shows the maximum power at around 120w. Temps are under 70c, voltage is well under Intel's maximum but can this old board handle much more than this without going poof?
There isn't a VRM temperature sensor on this board but there is a north bridge sensor which reads around 50c during stress testing. Touching the VRM side of the heatsink doesn't feel much hotter than it does when I touch the north bridge heatsink but this is far from accurate....
TL;DR, I'm pulling 120w through a very used low end motherboard, can I safely push more or should I leave it be? I need to ride this out until 7nm drops.
