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.

I died at $4000. Maybe remove a zero?

Hello. I just built my PC and everthing seems fine now. However I realized that a click sound is coming from PSU upon shutdown. Here is a sound of video which is exactly same with mine.
Is this normal? I experienced something like this first time.

Also when I start my PC for the first time, it made similar sound and looked like starting but then powered off like I changed somethings in BIOS and then powered on again with a screen indicating You have changed CPU or memory please go BIOS. But then everything is working great. Is this also normal?

If you're still interested in tweaking more It looks like your memory speed or uncore speed is slowing you down. My x5670 is scoring 1955 at only 4GHz (167 x 24). Memory is at 1670MHz and the uncore is at 3507MHz.

@bleu a change of thermal pads on the VRM heatsink and thermal paste on NB will not do any harm. You might push you OC a bit higher to something like 4.2 or 4.4 if you need it, but a fan on top of the VRM and NB is requiered because they will get really hot. OC on the RAM will also help to speed it up.
I use P6T - probably the worst VRM out all X58 and it runs at 4.2 without any problems.

@bleu While the VRM isn't exactly amazing on that board, it should still be alright. Check the top heatsink, not the one connected with the heatpipe to the NB; the NB is the part that gets really hot on those boards (taking off the blue covers and adding a fan helps a lot), at least it did on my board. While a cheap board its still pretty decent.
