Trying to answer some questions that haven't been answered:

The motherboard problem isn't much of an issue if there's any airflow nearby. Just make sure you grab a board with 8 pin+ 4 pin power connectors for the CPU.

I know you have a Sunday launch but would rather have a next Sunday launch to get a carefully prepared CPU. I have not liquid cooled motherboard VRMs before but this rounds looks to call for it.

TLC is our bread and butter- we won't ship unless we're confident. smile.gif

in any case i will be waiting for the rampage 6 extreme or apex and i guess those will he fine and my cpu of choice will be either the octa or the 10 core

I would wait for some of the newer boards coming out in the next few months if you're really wanting push a 7980XE hard. The R6E and Apex are both very promising boards.

One of my 7900X's "preferred cores" is actually not stable at stock settings (4.5 GHz) under a single-threaded AVX512 test. And the BIOS is apparently not applying any AVX or AVX512 offset by default. I'm tempted to point the finger at the motherboard/BIOS rather than the CPU itself.

The thermals are part of the issue that was holding us up. Some 7900Xs throttle at 1.05V before delidding under a full AVX512 load (just look at the latest Intel linpack). Without being able to set different voltages along with the AVX/AVX512 offsets, it's hard to push the non-AVX frequency on these chips without hitting a voltage that will cause AVX-512 to throttle. As I mentioned in our emails, I've had frequency/power throttling issues with Gigabyte boards with or without AVX. I think it's just an early bios thing.

Edit; Thanks for the info and your work

As above, the lower the voltage we use to test with, the lower we will be able to advertise non-AVX clocks. It gets pretty extreme, so we have to find a balance between the two.

Keep up the good work and thanks for the info!

These are not low temperature CPUs. Kaby lake(14nm+) was a fireball itself compared to Skylake(14nm), and these are multiple 14nm+ cores all crammed up next to each other.

Pricing will be available tomorrow at launch.

Sticking to one single voltage makes the high leakage parts look artificially good. They do tend to go furthest on the least voltage, but they are often so hard to cool that the practical clock limits can be lower.

This is a problem we were faced with. Things get really messy the more variables we have, and we were trying to reduce variables starting with this launch to make things simpler. We have settled with a compromise between testing with a high and low voltage, to where the low leakage parts almost meet the high leakage parts in the middle.

Are the "just de-lidded" chips the binned chips that don't make the cut?

yeah thats what i am thinking about too.
are the normal delidded chips the ones with bad oc potential?

We only sell binned chips, the listings up now are just placeholders.

Just the 7800Xs and 7820Xs will be going up tonight.

We have to re-validate our 7900Xs- these motherboards have been doing some additional throttling in the background without me even noticing. This has been a pretty painful launch trying to get everything working right. The Asus boards have been giving me the least trouble so far, and will be what we will use for validation from this point on for now.

so you recommend Asus boards like x299 deluxe for running 7900x?

Honestly for the 7900X, I'd recommend waiting a couple months for new X299 boards coming out which should hopefully do better with high workloads.

Otherwise, all Asus X299 boards I've tested (strix, deluxe, X299-A) behave pretty close to each other.

is it cause of the vrm issue "der 8auer" talked about? high temps like 100 degree on the vrms on full workload?
or do you mean something else?
so are the boards completly useless on full work load?

They are far from useless. If you lock yourself in at 1.1V, you won't have any problems or throttling anywhere, and can still get decent overclocks. The problems only arise when trying to eat more of the headroom available on the architecture, power consumption goes through the roof.
