Upgraded VRAM in Q700, still only 256 colors?
Posted by: 9646gt on 2020-08-14 11:44:36
Hey guys. I installed six 256k 80ns 670-0269 VRAM sims in the Quadra 700. Hooked up to a Macintosh Color Display M1212 which specs say supports up to 16.7 mil colors I still only see 256 colors as the highest option. I should now have the full 2MB right? Is there a method in OS 8.1 to see the amount of recognized VRAM?

It should just work out the box - you have the right modules and speeds.  I'd clean connectors on both the modules and VRAM connectors, switch things around, try 2 x 256K modules at first then put the other four in.

I’m not sure what the deal is. The memory looks brand new and the slots were clean. I wish there was a way to see how much the system was recognizing was installed. I’m sure this monitor was meant to be used at 256 colors but I can’t imagine that being all that a trinitron tube would support.

It's your VRAM, not a limitation of the CRT - I've come across a few dud VRAM modules over the years.  You can check VRAM amount using a utility such as Norton's System Info.

Thank you. I’ll check with Norton. Is system info in Norton system works or Norton utilities?

I installed system info from NU 3.5.3 and it doesn’t mention VRAM amount anywhere.

Got it! Finally reseated all the VRAM again and now it works. Thanks for helping!

Great news!  The old module switch-er-roo often comes up trumps.
