What is Synch?

I've got some ****ing ram here and I wanna shove it in my iMac, only I don't know if it will break it. Can any of you Mac gurus here can tell me which one of these are good?

Stick 1: Micron

Code:
(Micron Symbol) MT4LSDT1664AG-133C1 PC133U-333-542-C           
   US     BZABXQW020     200309                                                           
   128, SYNCH, 133Mhz, CL3

Stick 2: (Micron)

Code:
  16X64     16X64s7g4c8nMIC1002                                                       
   PC100                                                                                                
   222-620                                                                                            
   13121132591040303nm VOID IF REMOVED

Stick 3: (Hyundai)

Code:
 HYM7V65801     HYUNDAI                                                                  
   BTFG-10S BA-A     KOREA                                                                  
   PC100-322-620     0035

All those sticks look to be old memory from the PC100-PC133 days. If your iMac uses DDR memory or labeled with a 4 digit number speed (like PC2100, PC2700, PC3200, etc) then no your sticks will not work. Physically they will not fit either.

But with how old that Mac appears to be I don't know if Mac only recently started using PC spec memory or has always used PC type memory (our Sun stations at work use some funky memory).

Not too knowledgeable about PowerPC family numbers but he's on a machine with a 400MHz CPU and 100MHz system bus so it's very likely a G3.

The second stick (Micron) seems to best in terms of latency (lowest of the three; 222 vs 322 and 333).

Also, does that 16x64 mean that it's a 1045MB/1GB chip? In which case it would also be the best in terms of size (can't derive the size of the third though)

Do you have any information on the size of the chips? I guess it'll come down to this order of priority:
1) Size
2) Latency (222 vs 322 vs 333)
2) 100MHz vs 133Mhz (though your system bus is 100MHz so no big deal I guess?)


You know where to install your RAM chip right? At the back of your iMac (am guessing it's the gumdrop all-in-one CRT one) there's an access door.. Flip it open and you'll see the RAM slots IIRC.

See if they're physically similar (same width) before you proceed.

Be gentle when figuring out which direction to slot them in (only one direction should work) and you should be fine.

Just put them in. If they fit, which they should, it won't hurt anything. If they are not compatible it won't do any kind of damage to your hardware.
