How many have had terrible Haswell K chips

Just posing a random question to see how many Gerbils have personally experienced useless 4770K chips?

It’s sort of ironic. Knowing how good “Core” was going to be, I bought one of the launch day E6300’s. Those turned out to be very leaky chips, but leaky chips also make for great OCers and I took that 1.86 Ghz chip to a 24/7 stable 3.8Ghz under water. I figured why not repeat that, so I bought a launch day 4770K. Not sure about leakiness and it took a great deal of testing, but I figured out “the wall” was 4.3Ghz, so I left it at 4.2Ghz. A month later, the chip had degraded to the point it no longer was stable at anything above 4Ghz! I now regret not buying a vanilla 4770 g nike id iven this is basically a 4770 with features I could use disabled, but such is hindsight.

Delidders still run into the same pro nike id blems. A direct contact solution does help allievate the thermal paste issue, but Ivy Bridge and Haswell do get very toasty when you feed it the volts needed for high clockspeeds. It is hard to keep it cool with air when you go beyond 4.5Ghz. Water and Vapor chilling are the only viable cooling solutions at 5.0Ghz and beyond.

here is the thing. be it my opinion overvolting haswell is a mixed bag. and possibly detrimental.

it was engineered to fight arm and not overclock, this is NOT a surprise as tr and every other site noted. the IPC and draw (amp) trimming resulted in a chip that will normally not hit 4.5+ due to it being designed to be better.

the bad part. overvolting SB or older cpus was fine. it was designed to ramp. and designed to handle higher draw(am nike id p)/voltages. with overvolting you are actually putting more “wear” on the silicon. (thermal magnetizing, electron scaring, excessive gate wearing at increased load. and more) i think we will see “badly” tuned cpus fail after a few years of abuse instead of 5 6+ years for badly tuned (overclocked) setups from the socket 1156/1155 days.

Didn’t you also uncap yours? Not a fair comparison IMO.

Not as good a deal as the Cooler Master Seidon 120M I got (new) from Newegg for $25 after MIR a month or two ago. There’s a reason why the overclocker arenas are going the extra mile to get a Sandy Bridge chip over Haswell/Ivy Bridge if possible. 22nm and 3D transistor tech wasn’t build for handling volts and scaling stupidly high. It was build to make the silicon to cheaper to make and reduce the voltage at lower clockspeeds. This make sense perfect business sense for Intel.

The crazy overclocks with 22nm parts are using LN2 and a stupid amount of volts to keep the chips stable far more than their 32nm predecessors. The whole thermal paste issue adds another variable to the whole thing. This annoys overclockers who aren’t as adventurous and aren’t willing to delid the heatspreader. Delidding just gives you more thermal headroom to deal with the overvolting.

I guess I could’ve phrased myself better. To be clear, I never did “expect” good OCing from Haswell as I knew about the thermal goop and Ivy. I figured I had decent odds of 4.4Ghz and I would’ve been very happy to get that out of my chip. I use a triple 140mm radiator so cooling the hotheaded chip was not a big deal either, I kept coretemps to 75c or less during regular use.

What I did NOT expect, was that the chip would require 1.26v to hit 4.2Ghz. That I could at least live with. What I can’t live with is that it now requires 1.20v to remain stable at 4Ghz, basically a little over its max turbo freq!

OK, I rebooted my machine just to help y’all out and here are the pertinent settings:

1. CPU Core Voltage offset +0.150 volts. That puts maximum theoretical voltage at just shy of 1.3V given the base. That’s nothing to be terrified of.
