Re: So, mechanical keyboards

So, I managed to brick my venerated Ducky Zero 2108, with my preferred Cherry MX Black switches, by flashing the wrong firmware. In my defense, it was on the Ducky firmware page, MARKED AS A FIRMWARE UPDATE TO MY KEYBOARD THAT FIXED THE PROBLEM I WAS HAVING. I'm not a little annoyed. Wouldn't it be...

Re: 16 core CPUs with a single RAM channel are AWESOME

But even this doesn't make sense, because if I have an ideally-scaling n-way memory-bound job -- the only scenario where your gedankenexperiment matters -- then if I run it on the top i9 I can get it running 18-way and being fed at 4.7 GB/s per core, but this is not better than on TR2 because when ...

Not through tight optimisation of some software stack but straight out plain bashing of x86 on general purpose mixed integer/FP code like what I might write and use.

Re: Ryzen stable now?

It's a new chipset (and I don't trust Asmedia for anything), so if you really want to be sure, wait 6 months. In any case, coming from a 7700k hardly seems like an upgrade. You'll be losing a some performance in gaming and lightly threaded workloads. You'd have to really need those additional cores...

Re: RyZen+ Preorder: DO IT NOW!

I'm not sure that you can credit clock headroom on the new process; They've simply bumped the voltage in the case of the 2700X and that's resulted in the extra power draw. I have an R7 1800X running at 4.1GHz with an overvolt to 1.375V and that's without XFR, so it's directly comparable to the 3.7G...

Re: RyZen+ Preorder: DO IT NOW!

The 2700X looks great but I can't justify $329 for ~10% upgrade (vs my current 1700X).

I couldn't find a clear summary of the advantages of X470 vs X370? Anyone know?

Try setting the fan to something low in the Radeon drivers and see what happens. Maybe it's just bad design and they are indeed very noisy. Although that would be a terrible decision on ASUS's part.
