I know it's an old chip guys but it's as far as 1155 takes me so please don't judge too badly please. :eek:

Does anyone who ever owned one of these recall what the voltages were like pre and post OC? I ask because mine has always been 1.246-1.336V at stock (1.596-3.891GHz, single core max 4.190). This translates to 73*C max even with a D14. Recently I tried undervolting as low as 0.95V and max temps dropped to 65*C even under a Prime95 stress test. This went fine for a few days until it crashed again while a flight sim was running last night.

My 3570K runs 1.061-1.201V stock and tops out at 62*C with a measly Corsair H60. Folks on other forums are saying 1.1-1.2 on the 3770K is adequate for up to 4.3GHz and 1.3+ is waay too much, so at the end of the day does this essentially mean I just have a very badly binned chip? Hoping to take this up to 4.5GHz with custom watercooling but not so hot on adding more voltage (hehe, pun) if it's already using 1.3V @ 3.9Ghz.

You think the 3770k is an old chip? lol

The voltage for the 3770k does seem high are you comparing the 3570k stock voltage using the same motherboard?

It's old enough haha, but then again high-end parts from that generation are cheap enough these days to play with and not break the bank so I'll stick with what I have. :p

The 3770K is on an MSI Mpower Z77 and 3570K is on an MSI Z68A GD65. Does the motherboard play a big part in these things?

The motherboard can play a part but I dare say your 3770k is just needing a bit more juice.

You should probably be using manual voltage settings anyway and overclocking those chips to see what they can really do.

I'll try setting 1.3 manually and seeing how high I can get away with that. Thanks Saul.
