I just got my 3770K today (Thanks I.M.O.G. for going out of your way to pick it up for me
) and so far I'm doing a relatively short session of Prime/Blend on it for a quick and dirty stability test. I have it at 4.5 with a load vcore of 1.184 (set at 1.165 on LL1 in bios) and so far it looks to be hotter than the 2600K I was running in that system, but is achieving that overclock with quite a bit less vcore. The setup is as follows:
Asrock P67 Extreme6 board with beta bios L2.02
4 X 4 GB G. Skill Ripjaws X + Turbulence DDR3-2133 ram
EVGA GTX260/216 vid card
Custom loop consisting of an older Swiftech GTZ cpu block, MCP355 pump on BayRes1, Swiftech MCW60 gpu block on vid card, XSPC RX360 rad and a HWLabs GTX140, push pull fan setup on both rads.
A few things I have already noted since the switch:
Load wattage on the 2600K, as read by my APC UPS (total system load), running only P95 blend and no load on vid card - 278-281 watts
Load wattage on the 3770K, as read by my APC UPS (total system load), running only P95 blend and no load on vid card - 234-237 watts
Max temp on hottest core of 2600K running P95 Blend (1 hour run) - 66 C
Max temp on hottest core of 3770K running P95 Blend (2 hour run) - 74 C
Load vcore on 2600K @ 4.5 was 1.328v
Load vcore on 3770K @ 4.5 is 1.192v
@ IntelEnthusiast, could you pass along to your contacts in Intel that I would pay $10-20 more for a processor if they would quit cheaping out on Ivy Bridge using TIM in between the core and IHS and go back to using the fluxless solder process to bond the IHS to the core. The fluxless solder process conducts heat soooo much better than the old fashioned and inefficient TIM they are using on IB. I am seeing 10 C difference in max temps so far between the cores, which is much higher than I have seen with the 2-2600K, 1-2500K, 980X, i7 930 and even the old QX9650 in my daughter's system. All those use the fluxless solder TIM bonding process and all are more even on core temperature consistency.
EDIT: Finished a 2 hour P95/Blend run successfully and updated vcore and load temp in post.
