Source of 1MB L2 Cache Modules for PM 6/7/8100s and others


Recommended Posts

Hi Guys,

 

Not sure if you guys have any use for this but I figure it can't hurt to share the information.

 

While most Power Macs these days can or have been upgraded with either a G3 or G4 accelerator containing an exuberant amount of L2 (or even L3) cache on-board generally, in some cases, machines such as the Performa 6100/66 can't really utilize an accelerator if using either a Nubus or DOS Compatibility Card. Since I still wanted to be able to have a somewhat responsive system but without sacrificing my DOS Card, I had been looking for ways to somewhat improve the overall performance. I had been using 256KB of L2 cache so far but I had heard of the existence of a 1024KB (1MB) L2 cache module. Let me tell you, I've had a hell of a time finding one (these buggers seem to be rather elusive!) - until now!

 

Searching the almighty interweb I stumbled upon the site of a company named "Data Memory Systems" which still seems to have some on-hand stock of L2 cache modules. I figured I'd give ordering one a try so I ended up ordering the 1MB L2 Cache Module for the 6100/7100/8100 series of Power Macs, and at $2,-- per module - which included shipping nonetheless - I figured heck why not.

 

I am happy to report that I did indeed receive a L2 cache module rather than an email stating that they're out of stock but haven't had a chance to update their site yet! It's pretty big and heavy in comparison to the 256KB module (I'm scared of it somehow ... in a really strange way) but it certainly works like a charm! The performance increase is quite noticeable, even in comparison to the 256KB module.

 

Anyway, if there are more oddballs like myself who either can't or won't upgrade to a G3 accelerator, here's the link to the site (also, if accessing from the main page, scroll to the "Clearance Items" and then to "Apple VRAM & L2 Cache Cards"):

I have to admit that the description for this one isn't very specific. One can only assume at this point, but according to VRAM Chart (http://support.apple.com/kb/TA29136?viewlocale=en_US), if it's 68pin VRAM then just about all of the LC/Performa/Quadra/Centris could use it. Guess it's time to call/email in order to find out more details (speed, etc.) :)
