My real trouble is the probability of a high and safely sustainable overclock which is seemingly going to be hit and miss worse than ivy. What all these posts are not telling us is the increased probability of getting chips that will not OC as well as the engineering samples shown which is exactly what many have experienced with ivy in the near past. So I'd rather the ivy devil I know in this case. If the gains are 5-7% ivy to haswell what makes you think that OC clock for clock will yield anything better if not worse due to other factors that don't scale linearly in the real world? It still isn't worth it as the gains in OC are too measly to even make any difference in titles that matter like BF3 and Crysis 3 and warrant the premium that they are going to be selling at when they finally touch base in a store nearby you.

There is always going to be a trade off with an intel chip from the times of Core 2 architecture to present. If it is not the heat limit it is the OC potential if not that it must be the vcore required if not that it will jump back at the heat being enough to degrade your chip rapidly or you just have more trouble with the lottery than previous architecture.

Intel just needs to use solder and charge a little more. But in the end its about money, so if they can sell more CPU's while making them for less, that's what they are going to do. Its no surprise the higher end CPU's run cooler and make better contact with the IHS over these so called budget chips.

I just bought an i7 3770k yesterday at an offer price, can't wait to see what its batch has to offer. The i7 is coming in solely from previous i5 sale xD

Maybe they can't solder due to the transistor die size? Has anyone given that thought?

The motherboard was also at a discounted price and will be a while before I get it since I got them from two different places mainly because they were on offer. I went with Asus (that has twice a beefier VRM setup) this time instead of my previous Gigabyte preference. Apparently, its the second time I have had problems with Gigabyte and heavy overclocks.

I finally got my cooler running 3570k on a board with more options and power phases, MSI Z77A-GD65. I've got it dead stable at 4.6, 1.36V 85c at the hottest. It required 1.5x power frequency just to get it to post into windows and be stable. It is pulling nearly 99w. It isn't pulling up any better Gflops at 4.6 than at 4.5. Do you guys think I'm hitting a point of diminishing performance returns due to being so close to the thermal limit? Would better cooling address this?

It's kinda strange that Gflops didn't change a bit with the frequency increase, better cooling never hurts but don't know if that alone would make things better with no other changes.
It will be using more than 99 watts, there is no software that will read the power the cpu uses properly.

It you are sure it's totally stable, there's something suspicious going on.

If you don't yet know if it's really stable, I have screenshots of the same multiplier doing different GFlops at different voltage. One screenshot shows 4.9 GHz at 1.43 V and about 130 GFlops, the second shows 1.44 V and 132 GFlops. It still ran remarkably stable in that first screenshot. It was twenty passes at 4 GB size of the test IBT does. It failed prime95 after an hour or so.

I'd say you should try to see what your GFlops look like at 1.37 V or 1.38 V.

4.6 Ghz tracks w/ your Gigaflops @ 118, 4.5 is about 115 and this is mostly on high settings. It just isn't massively dramatic in scaling it seems.

Is there anything out there that says that as you get closer to a processor's thermal limit that processing throughput goes down?
