The Pickle strikes again--mostly :-) Inspected the card, and the cache is present (it's a daughtercard with chips on it, adjacent to where the 68040 CPU plugs into the main board of the upgrade card -- just like it's drawn in the Daystar user guide). This one has 8 32k chips on it, rather than 2 128's or 4 64's.
As for the OS, I obtained this machine with 7.6.1 already on it, but the proper Control Panel was installed, and AFAIK the previous owner did a fresh install of the OS when he first put in the upgrade card. Nevertheless, I did a clean install of OS 8.1 anyway, and was pleasantly surprised to see that it improved my MacBench CPU score by 1% and the FPU score by 13%. I'd assumed that 8.1 would be slower. Finally, in total frustration, I used TomeViewer to pull out the Apple System Profiler from the OS 9 install CD -- the 7.6.1 and 8.1 versions of the Profiler don't report anything about cache (grrr....). So the OS 9 Profiler reports 256k L2 cache. Finally, I loaded an old copy of TechTool Pro and ran the cache test, which (in addition to testing the L1 cache) tests the L2 cache for (a) presence and (b) functionality. Sure enough, the machine passed the L2 cache test. So it's possible that the fresh install of OS 8.1 helped things -- perhaps the MacBench increases were due to the newly enabled cache rather than any speed benefits of 8.1 itself. But I doubt the new OS install was the reason, as TattleTech still reports the cache as not enabled. I think that the cache was enabled and functioning all along, and I just didn't know it. Oh well, stupid me. Thanks to the Pickle for taking the time to respond, and thanks to everyone else for the bandwith :-) Best, Matt On Sunday, February 9, 2003, at 05:59 PM, the pickle wrote: > Does it really have an L2 cache? :) Check for the presence of the > chips > themselves; I don't know for certain what part numbers you're looking > for but > they should be some sort of fast RAM, probably in a group of two (128K > each) or > four (64K each) identical chips. > > Cache-22 may not like upgrade cards in general; what happens when you > run it > with the card removed? > > I think the Daystar PowerControl is only for the PowerCard and PowerPro > upgrades, which would explain its reticence here. > > Did you do a fresh install of the OS when you installed the card? > > Things it probably isn't: > > - the 040 cache mode, since the 040 is turned off completely when the > PPC is > active > - anything else related to the 040, for the same reason > -- > > the pickle > > FAQ <http://macfaq.org/index.shtml> > _________________________________________________________________ > > -- > Quadlist is sponsored by <http://lowendmac.com/> and... > > Small Dog Electronics http://www.smalldog.com | Enter To Win A | > -- Canon PowerShot Digital Cameras start at $299 | Free iBook! | > > Support Low End Mac <http://lowendmac.com/lists/support.html> > > Quadlist info: <http://lowendmac.com/lists/quadlist.shtml> > The FAQ: <http://macfaq.org/> > --> AOL users, remove "mailto:"; > Send list messages to: <mailto:[EMAIL PROTECTED]> > To unsubscribe, email: <mailto:[EMAIL PROTECTED]> > For digest mode, email: <mailto:[EMAIL PROTECTED]> > Subscription questions: <mailto:[EMAIL PROTECTED]> > Archive: <http://www.mail-archive.com/quadlist%40mail.maclaunch.com/> > > Using a Mac?
