Comment Re:Remove the "intel inside" stickers (Score 1) 43

I have an "Intel Underside" sticker on a riscv64 board. Some vendor dumped a bunch of 16GB Optane nvme modules at ridiculously low price; I guess they got a shipment of laptops with these marketed as "accelerators" and had no use for the modules. The "accelerator" idea was broken because of Windows being inept of making any good use of them. On the other hand, for a proper operating system, a 16GB disk is plenty enough. This way, instead of some lousy SD card I got much faster than Flash nvme.

And it prevents infecting others, too! Compare: bleach + ivermectin + cremation: removes pain quickly, stops the disease, stops further spread after the treatment is complete. Whereas, science-based medicine leaves patients suffering a lot of maladies, including but not restricted to, old age related diseases.

Or more likely, trying to source smaller memory chips would cost more. And as C64 already uses bank switching, there's no reason to not allow switching to more banks. Like, C128 shipped with 128KB, could be easily extended to 256KB, and its CPU could handle up to 640KB.

As 128MB = 32768 4KB pages or 65536 2KB pages (I don't know the granularity of the I/O port used for bank switching), I suspect this limit is due to bank numbers not the memory chips' size.

And the fun thing being, original software that was able to handle different memory sizes (64/128/256/640) might be able to use all 128MB without modifications.

s/done/sometimes done/
Try attaching any monitor above 1920x1080 via HDMI. So if the cable is known to be good, the computers in question have all "HDMI 2.0 4k" in big letters in their specs, all should work, right? Mwahahaha.

The particular case on my disk right now: EDID and DDC properly report 1920x1200 (native), 1920x1080, 1600x1200, etc., yet it fails to work in the first mode. 1920x1200 needs HDMI 1.4 bandwidth, the two other HDMI 1.3. The same monitor, the same cable work with some computers, fail with others. Hrm.

My low-res monitors are DVI, which is supposed to be carried over HDMI (same protocol), but guess what? It's also random which computers they work with.

Meanwhile, in the DP land, I have yet to see my first failure. But sometimes I need HDMI for $REASON. :/

Likewise with PCI 4.0 cards in a PCI 3.0 motherboard:
[ 0.768734] [ T1] pci 0000:43:00.0: 126.016 Gb/s available PCIe bandwidth, limited by 8.0 GT/s PCIe x16 link at 0000:40:03.1 (capable of 252.048 Gb/s with 16.0 GT/s PCIe x16 link)
or in a physically-x16-really-x4 slot:
[ 0.777737][ T1] pci 0000:09:00.0: 31.504 Gb/s available PCIe bandwidth, limited by 8.0 GT/s PCIe x4 link at 0000:00:03.1 (capable of 126.024 Gb/s with 16.0 GT/s PCIe x8 link)

The second card has same problem as yours, when in a real x16 slot it'd use only 8 lanes despite physically having the connectors.
