Quadra 650 VRAM

[tecneeq]

Before i order 2x 512kb VRAM for my Quadra 650:

1. Is there any information i need to know in regards to latency of the chips and a 40MHz overclock?
2. Is it possible to use 2x 1MB VRAM? The documentation i have found says 2x 512 is all that's possible.

I can answer my own question:

1. 80ns is fine
2. 512kb are onboard, to get the maximum of 1MB you need 2x 256kb. Once again Everymac has wrong information:

Looking to expand my own 650 a bit: Where are you buying your VRAM?

No need for me, i already have 2x 256kB. But if i had to buy new, i would consider those in 80ns:

1pcs PurpleRAM new 68pin SIMM 256k 80/70ns VRAM memory Apple Macintosh computers | eBay

1pcs PurpleRAM new 68pin SIMM 256k 80/70ns VRAM memory Apple Macintosh computers | Computers/Tablets & Networking, Computer Components & Parts, Memory (RAM) | eBay!

Agreed, @Siliconinsider 's purple RAM is solid.

Also see through mac, which is epic in itself.

Good - those are the ones I had in mind!
Let's hope there's some left in stock for when I get around to it - Xmas isn't cheap :/
