The artifacting reduced by 95% when using the 33 MHz front-side bus on the Daewoo board, compared to 40 MHz on the Asus board. Whether the artifacting is due to an overloaded bus on a long/crowded PCB, or due to or ageing silicon, I don't know, but I suspect the former. I don't think Diamond had a whole lot of sales with the MVP-2000 targeting the VLB platform. Looking through the manual, the VLB variant notes show up in the addendum.
Even with the artificating, it only shows up temporarily on the screen surrounding the overlay box. Once you refresh the desktop, the artifacting disappears. It would be interesting to test the same MVP-2000 board in a PCI system with a 40 MHz FSB.
Any idea who IBM was buying the VRAM from in 1994-1995?
Speaking of the VRAM, the NEC memory I had ordered had some of the surface print ruined (evident on page 2). This was because the manufacturer had placed tape over the IC's to hold them onto a foam backing board. I'm not sure why they weren't sold in tubes. Possible fakes? Removing the tape pulled some of the wording off. I was able to fix the wording, for the most part, using some thermal grease and isopropyl. The lack of consistency in the black colour on the casing of the IC makes me suspect they are fakes. Has anyone seen this non-homogeneous zone in the black plastic casing on memory modules?
Shown below are the fixes. Goofed up RAM print is on page 2 of this thread, here: download/file.php?id=131329&mode=view
