There are even some AM3+ boards with 64GB memory support, but no modules to max them out. Crucial still doesn't list non-ecc 16GB memory sticks on their web site.

And with DDR4 due out later this year.... :hmm:

Sure those AM3+ boards didnt support server memory?

Yea I don't see Intel bothering to replace the TIM on non-K parts. They already run well within spec and can't be pushed.

They really dont, I have a stock 4770 non K, stock turbo and everything, heavy avx loads will make it throttle (during winter times no less, summer is coming so its bound to get worse).
I am far from the only one.

By throttle do you mean below 3400?

But it raises the question again, where are those modules. You cant say Intel is "limiting" if what they are supposed to limit doesnt exist.

I am not saying anything, Shintai. And I agree with you, that is the problem with memory suppliers, not with Intel or AMD 😉
 
Several people have commented on the power consumption numbers in the review. According to the chart they benchmarked this with 3DMark 11 which is ... an interesting choice. Clearly all of these chips can consume more as this wouldn't really load 8 full threads. I guess we will know more next week as the rumor is that the non-k processors are released tomorrow.

Then stick an aftermarket heatsink on it. I run 4770's and I always slap a heatsink on it. Keeps it ice cold. Last I pushed it with Handbrake it cracked around 50 celsius and was up around 3.8GHz. The stock cooler is junk.

Maybe you have a bad chip or bad airflow? My 4770k never has dipped below 3.5
It actually regularly sits at 3.8+ for some reason.
This is why we don't judge off one chip but off reviews /batches of chops.

I'm on stock cooling as well.

I'm sure you've checked already, but that sounds more like an issue with the HSF mount than an issue with the processor.

At stock configuration (Vcc, etc) with stock cooling, your 4770 should have no problem sustaining full-load at stock clockspeed indefinitely.

If it doesn't, then you should seek to RMA it the same as you would any other sub-par product.

What you describe is definitely not what Intel expects the product to perform like, something has gone awry and you shouldn't settle for it as is.
 
This does seem alittle too good to be true tho. But we know soon enough.

I got two large fans spinning air out of the case (case has special vents for this), flow shouldnt be a problem.
While I only have *personal* experience with one haswell chip, these stories are not hard to find, we have had a few here alone and I suspect the reason why not more is hitting the issue is because they're not running heavy avx loads and not using the stock cooler. I can game on this thing for hours and never throttle, last i checked temps were around 75ish, however load up the avx2 version of prime95, let it run for 10-15 minutes and bang.. throttle time.

- Yea I would problary do that IF i wouldnt be without a CPU for the duration AND if I didnt get the impression that the fault is rather generic. The cure is simple, just dont run the avx2 version of prime95 (or any other avx heavy app im sure) and its good to go.

As for the hsf mount, other than the avx scenario temps looks to be in range with everyone else running stock.

That looks mighty fine. I'm waiting on Haswell-E to upgrade my system, but this looks like a pretty worthy upgrade for somebody with a Nehalem/Westmere/Sandy Bridge looking for more oomph and a better platform.

I wonder, though, if Broadwell-K will actually be any better on the overclocking front or if the process/design will be so optimized for low power that there won't be all that much headroom?

Given that Haswell Refresh is guaranteed to have a reworked mask set, I'm betting we are going to see a power consumption reduction (which begets a temperature reduction provided the thermal conductivity remains unchanged at the worst) simply due to the layout engineers having had another year to optimize the routings and xtor blocks over that which the original Haswell layout team was given.

Ugh, please don't remind me of the "Let's just tape out the base layer and keep submitting ECOs to the physical designers because they have nothing better to do" BS that I experience everyday at work, just so some management a*shole can claim that "they taped out" :|
