Re: AMD EPYC 7002 - Rome wasn't built at 14 nm

This is an unequivocal home run for AMD in the server. Only unknown keeping it from a grand slam is supply which I foresee them being able to see every chip that they can make for the next year. Of course my ego can think of a few things more that I wish AMD did: ⋅ Quad socket support &sdo...

Re: Does this exist? VNC-like remote access through a sort-of KVM?

Designed to provide connectivity to systems that didn't have normal remote access etc. Old job had some of these accessible from the OoB network for trouble shooting some devic...

Re: That make me CRAYzy

It wasn't too long ago that HPE bought SGI and with it their NUMAlink interconnect. This merger has had some HPE product come from it (it also helped that HPE was previously rebranding a high socket count SGI box). Cray is more puzzling. Cray of course does system builds but that is nothing special ...

Their launch windows look to be close with June being floated around for Ryzen 3 from various manufacture...

Re: RyZen 2 Desktop CONFIRMED... to not have 16 cores

Given how much larger the I/O chip is than the actual cores, and given some of the rumors surrounding Epyc, I have a controversial theory: I think that to make that chiplet smaller, AMD put the L3 cache on the I/O hub chip and that chiplet is just Cores + L2 caches + the I/O interface circuitry.

Re: DisplayPort problems

Does the MSI display have an option for HBR2 mode? Try toggling that on the display.

I would also attempt to use the different DP connectors on the RX580 to see if this changes anything with the different cabling schemas.

Re: why monitors have better picture than tvs?

Re: why monitors have better picture than tvs?

There are several things that effect how off consumer TV's can be "off". First is that HDMI on the consumer side has a limited range for RGB, 0 to 231 instead of the expected 0 to 255 values for each color component. The second aspect is that TV's may operate in YUC mode instead of RGB. Th...

Re: What's the latest with Intel Thunderbolt 3 integration?

My working theory is that we'll be seeing Thunderbolt 3/4 in iPads and iPhones next year. Beyond that, there is a chance that nVidia and AMD have both licensed it for inclusion on their GPUs. This would be a timely coincidence as Intel has had to fuse of the GPU on the few 10 nm Cannon Lake parts th...

Re: PCI-E x1 on a PCI-E x16 slot?

The catch with a 16x slot is that it provides more power than a 1x/4x slot. Really low end cards might be fine as well as some high end cards with a good VRM/power balancing setup that are undervolted or otherwise intentionally throttled. The challenge are the 75W edge connector only cards.

Re: Intel Processor bug incoming?

Well it looks like Spectre can break into SMM. This follows on the heels of another SMM attack in recent memory, coincidentally introduced in the first chips that Spectre could also be used.

Oh, and there is Spectre NG on the way too.
