Ram backwards compatibity

[MadEye2]

I've just ordered a PC2700 DIMM to replace my PC2100. Could I use the PC2100 on motherboards that use PC100, PC125, or PC133 DIMMs?

Doubt it.

i think PC2100 and PC2700 are DDR. the PC100-133 are not DDR. they are SDRAM.

Ah well, may as well sell it then. Thanks

Reckon I could cram it in to the 72pin simm slot on my amiga?

If you are strong enough.

Lol.

While you're at it, you could try to slap a new Pentium-4 Northwood on your 440BX board. Sweet.

Pin incompatibility be damned!

Well, it was slightly too big, but i just hacked off part of it and it fit snuggly in to the slot, though the pins didn't line up. It seemed to work fine enough though, granted it could only map 32MB of it, the pcmcia slot didn't want to share resources and theres a strange smell eminating from the expansion slot. Now I'm considering removing the 50Mhz occilator on the blizzard card and replacing it with a 600Mhz one. By that logic I should get it to run at about 400mips - Alien Breed 3D 2 will run perfectly then.

Please go make a post in FS/T: "WTB: Sarcasm Detector. Mine's busted and I suck at the internet."

No, I'm serious. The A1200 could only map about 32MB using the Blizzard 68030 50Mhz board, and only about 16 if you wanted to keep the PCMCIA working. Not that that matters anyway as my SCSI Squirrel is a bit dead and I took the cables out of the CDROM drive (3.2x) and can no longer remember how they go back in. I think I may need a decent fan to make the 68030 operate with a 600MHz occilator, and it may even melt the keyboard. I'll try a 100MHz one. I won't be able to run Alien Bree 3D 2 with high quality graphics or even full screen but I should get about 30fps on it.

I think someone actually overclocked a 68030 with a 100MHz one, then again I've heard someone claiming to have clocked the 8MHz 68000 up to 100Mhz, which, if he wasn't lying would be pointless anyway because he wouldn't be able to use the AGA specific software that takes advantage of it.
