Hello! I've again read through "RAM doesn't work" here: http://groups.google.com/group/g3-5- list/browse_thread/thread/e3148b46f756e739/0603c6cf964a079c

I'm planning to replace faulty RAM in my Power Mac G4 MDD. It now has 1.5 GB of PC2700 DDR SDRAM from Kingston (not specific to Mac). But since there really is not difference, it worked well. Until now - one of the DIMMs broke down (is now faulty). I had to remove it. I want now 2 GB and read, that I can also use two 1 GB DIMMs instead of four 512 MB DIMMs, here: http://developer.apple.com/legacy/mac/library/documentation/Hardware/Developer_Notes/Macintosh_CPUs- G4/PowerMacG4Sept02/4Expansion/Mojave_expan.html#//apple_ref/doc/uid/TP40000922- CH208-TPXREF102 I quote: > The memory slots will accept four 512-MB DIMMs (also is capable of 2-1GB) > for a maximum memory size of 2 GB. I point out: "also is capable of 2-1GB"! Now, my MDD is the version with 167 MHz system bus speed, so it takes PC2700 RAM (instead of PC2100 for the 133 MHz system bus). More specifially, that is a 184-pin 333 MHz DDR memory module (DIMM). I'd love to get ECC memory though. And since Len wrote it worked for him with PC133 memory for his G4, I though: what's the difference? I quote again (same source as previous quote): > Important: DIMMs with any of the following features are not supported in the > Power Mac G4 computer: registers or buffers, PLLs, ECC, parity, or EDO RAM. So, _officially_ ECC RAM is *not* supported. Too bad. For me. I'm eager to hear if it worked for anyone here on this list. If so, I may give it a shot and by ECC memory instead of Non-ECC memory. I'm also eager to by two 1 GB DIMMs instead of four 512 MB DIMMs, since the price is lower for a total of 2 GB. Has anyone ever tried that?
