This comment in a recent post to the list caught my eye.
If that doesn't work i can find a copy of the last free version of XLR8 software. I'm still using it with my OS 9.2.2 install as had issues with the later versions. best of luck Will S
Which version of the XLR8 software do you use in OSX? I purchased my card in 2002. Since I'm still in OS9.1 should I stay with the software that came with the 450G4 from XLR8 or should I upgrade to their newer version? And when I plunge to OSX what should I do. Thanks Will. Paul C
I'm using XLR8 Speed Control 2.5.0 for OS 9.2.2 seems to work fine. I believe it's one of the last versions that were free for all to use. However it's been so long since I installed it not sure that it didn't require a serial number. I did try version 2.6 but I didn't like the way it looked and went back to 2.5 which seemed to work just as well. So I know of no reason to upgrade for OS 9 if things are working for you.
OSX well the original XLR8 software quit working long ago maybe 10.1 was the end for it not sure. There was a period of time when there was no XLR8 software which worked with the current OSX after apox 10.1 . Lucky for us Ryan's Cache configure software available at the XPFacto site worked fine for OSX 10.1.5 and I think Jaguar. However it doesn't let you turn the motherboard L2 cache off. Having this on it becomes a very slow running L3 cache and slows your CPU down a bit. Powerlogix Cache Control X is perhaps the best software for Jaguar for those with Umax and some Apple machines (original 8600& 9600 machines) which have soldiered on L2 cache. Reason being it lets you turn off the motherboard L2 cache.It also reports the temperature of your CPU which not all softwares do. Cache Control X is no longer available from Powerlogix's web site. I can send a copy to anyone who wants it. They have replaced it with Cache Director which runs fine but doesn't let you turn off the motherboard cache and doesn't report cpu temperature. It's mostly for newer machines and upgrades.
I recently upgraded my XLR8 carrier card with one of the new Daystar/XLR8 G4 550-600 MHz Zifs. I tried using the new Daystar/XLR8 Speed control version 3.0 which came with the Zif (sold separately for $18.00 currently) It crashed on my machine both Jaguar and Panther . So I went back to Powerlogix's Cache Control X which worked fine both Jaguar and Panther. I mentioned to Gary @Daystar that their software crashed on my machine and he sent me the new 3.0.1 version runs great! The amazing thing is Panther starts up in 1 min flat more or less using the Daystar software. It takes 2 1/2 min plus using the Powerlogix software. The Daystar software is also said to have many improvements for Altivec which are only seen when using a G4 CPU. Seems to be true to my surprise but doesn't make a difference using a G3 CPU. I can now play high quality.avi & Divx video files with no dropped frames or sync issues with the G4 cpu which the G3 even at 550 MHz chocked on.
I spent a fair amount of time fine tuning my Carrier card with Daystar G4 550-600 MHz Zif. Speed depends on bus speed of course. Our old machines won't run a fast enough bus speed to take full advantage of the 550-600 Zif of course. I really pushed the limits and found my machine would boot at 60 & 61 MHz bus speeds using the G4! However I started having RAM issues no surprises there .I've lost at least one RAM chip with every CPU upgrade it seems and even OSX upgrades have caused weak RAM chips to no longer work. (These same RAM chips however still work fine when booted into OS 9) The fix for the RAM issues was turning off the motherboard L2 cache by jumpering the J38 pins on the motherboard with a small drop of soldier or in my case using a silver circuit writer pen. I put a small fan blowing on the heat sink just to be on the safe side and Carrier card with G4 runs fine at 540 MHz @ a bus speed of 60 MHz. I was surprised to find that OS 9.2.2 would boot with scrambled Video at that speed. Dropping the bus speed to 59 MHz fixed the scrambled video in OS 9 . So I am how running at G4 530 MHz with a bus speed of 59 MHz. I think one reason this works so well is the Zif is rated at 550-600 MHz and Daystar tests each Zif they sell to run at 650 MHz. So unlike most Zif CPU's this one is not running overclocked but under clocked. So it doesn't fail from over heating as many of the G4 450- 500 Zif's might. No telling what this bus speed will do for long time use but it has been fine for going on 2 months and with really hot local weather ( lots of 90 -100 degree days)
Hope that answers your question. Will S
