BIGram vs ZorRam...

[Oldsmobile_Mike]

I recall a few posts about these when they first came out.  ZorRAM is compatible up to OS 4.1, BigRAM only up to 3.9, also BigRAM is a physically larger card (for those who care about that sort of thing), but I think it was also the first one to support up to 256MB, and should be a little bit cheaper.  I think one was designed by AmigaKit also, and the other by someone else?  Don't recall the rest of the details, sorry!

You might want to read this thread before you put a BigRAM or ZorRAM in your A4000.

Just skimmed to the bottom of this thread.  It seems like his problem was caused by a chip on the A4000 CPU board, not either of those memory boards.  Heck, if anything, the troubleshooting process he went through to get the memory board working actually fixed some kind of manufacturing defect on his CPU board.  Kudos!

The ZorRam works with a Cyberstorm MK1 and the BigRam Plus does not work.

That's a full house in that A4000!  Nice!  Probably won't make a difference but have you tried it with just the BigRam, and all the other cards removed?

By the way... the RapidRoad USB Module for the X-Surf 100 isn't compatible with the Cyberstorm MK1 aswell.

Ugh, dislike.    I'm probably not going to be in the market for an A4000 for at least another year or so, but as I love the RapidRoad in my A2000, that's good to know!
