Overclocking Escapades: socket LGA1155 Intel Core i7 3770K

[Tech Tweaker]

Had this CPU for probably a year and-a-half now. Figure it's time to see what it's capable of.

Batch number: 3231B442 (Costa Rica)
VID: 1.16V (apparently, it's what it defaults to with settings at Auto/Default)
3.9GHz (100MHz x39 Boost): 1.16-1.168V (Auto) *not yet tested for lowest voltage
4.5GHz (100MHz x 45): 1.136-1.152V (1.14V) (62°C max load temp)
4.6GHz (100MHz x 46): 1.176-1.192V (1.18V) (66°C max load temp)
4.7GHz (100MHz x 47): 1.264-1.272V (1.26V) (76°C max load temp)
4.8GHz (100MHz x 48): 1.320-1.336 (1.32V) (84°C max load temp)

Motherboard: Asus P8Z77-V Pro
Cooler: Noctua NH-D14
RAM: 2x2GB G.SKILL F3-12800CL7D-4GBRM (PSC chips) 1600MHz
Power Supply: Corsair CX600M

Got it up to 4.5GHz so far, started at 1.2V and began working the voltage down, so far down to 1.14V and still stable.

This CPU might be capable of 4.8-5GHz at lower voltage if the voltage required for 4.5GHz is any indication of its upper limits.

2600k?

Hey, if you happen to sell it sometime, I might be interested...

I used to have 3 2600k's. All were doing 5GHz below 1.5v IIRC.

But 1.14v for 4.5 is damn good. This one might do 5.1 stable around 1.5v if cooled recently and no hitting the voltage wall...

Give a [email protected]/1.45v maybe?

Edit: maybe I should read the title, lol!

Is it de-lidded1?

Mine was doing [email protected], but was hitting the wall there, and no way to [email protected] whatever the vcore bump.

Offer still valid if yours is [email protected]

No, it's not delidded that I know of.

As far as I know it never has been, but no guarantees there as I bought it used.

Looks like you won the silicon lottery with that one.

 

[Tech Tweaker]

Looks like 4.9GHz isn't possible with my cooling solution, with 1.38V it hit 95°C on the hottest core within just a couple of minutes of starting Prime95 Blend test and around 90-92°C on the coolest core.

 

[trents]

Delid.
