Quicksilver G4!
I found a Quicksilver G4 in a computer recycling bin today. Sticker says it's an 867 MHz, and it has no RAM or HD. I found it in pieces, but it has the logic board, PSU, optical, and zip drives.
I'm not going to be home until about 6:30 or so, so I'll try it out then.
Woo!

Even if one slot is fried, couldnt you just put in 3 512mb sticks to still get the maximum of 1.5gb? because at least 2 slots support 512mb sticks, if the RAM limit is 1.5gb, there would have to be 512x2 and 256x2.
still, quite a nice find. I have been trying to get a G4 system for under $100, which seems to be unobtanium lately.

it can only read PC133? I thought it was interchangeable. I know PC133 runs just fine in PC100 slots, it just throttles down. But PC133 slots should be perfectly compatible with PC100s. I know my mom's toshiba laptop takes PC2100, but i was using a PC2700 stick in the second slot. I tried the opposite, and the PC2100 worked just fine in a PC2700 slot. Maybe the stick is just totally dead...

You can't use PC100 memory in PC133 slot even though they are physically compatible. The memory would be overclocked 33%. You can put PC133 memory in a PC100 slot because it's not being overclocked.it can only read PC133? I thought it was interchangeable.

PC100 will not run in a PC133 board. Ok, sure you can cram the stick in there. Heck if it was a god module with an SPD chip it could run ok. However most of the time the answer is no.
By running the PC100 stick, he drops the bus from 133MHz to 100MHz. This places a large bottleneck in the system, which of course affects overall system performance.
Remind never to hire you as a tech.
Sigh...
Ok, look. On a PC-133 system, you can use either PC-133, or PC-100. If you run PC-133 this will ensure normal operation and keep the system bus at 133MHz. If you run PC-100 then the bus will drop to the highest speed of the slowest stick. In other words you drop the entire system bus from 133MHz to 100MHz. This is not good. Buy better RAM.
On a PC-100 system you can still run either module. Although some older systems have problems recognizing high density modules. Feel free to mix and match PC-100 and PC-133 sticks. If you stick a PC-66 stick in there, the same rule applies. The system bus will drop.
On a PC-66 system (G3's, PII, Celeron, K6, K5, etc.) you can run any damned module you want. There is nothing slower than PC-66 so go for it. Keep in mind though that the sticks must be SDRAM modules and not SIMMS. There are PC-66 SIMMS out there for a few franken-motherboards that appeared for a short time.

Sorry but I've tried moving memory out of PC100 machines into PC 133 machines and they DO NOT WORK EVER in my experience.
What you say also makes no sense because if the system bus drops, so does the speed of the CPU, the drives,and everything else that depends on the bus for it's timings. Putting a PC100 stick in a 533 Digital Audio (which I have never gotten to work anyway) would lower it to a 400mhz machine if your logic follows.
The bus should lower itself to the speed of the lowest RAM. In this case PC-100. Now on certain machines, the whole bus is effected. On some machines just the memory bus is affected. I am not sure if the QS will drop the whole system bus, or just the memory bus.
No way in hell does it auto-OC the RAM from PC-100 to PC-133.

Exactly. PC-100 does NOT work in PC-133 boards at PC-133 speeds. IME moving the RAM from a PC-100 machine to a PC-133 machine is hit and miss. Either it will work (albeit at slower speed), or it won't run at all. In the rare instance you can find PC-100 RAM that is happy at PC-133 speeds.
For what it's worth the physical ram ceiling of a QuickSilver is actually 2 gigs, and OS X can address and use that much, the stated limit of 1.5 gigs was for the benefit of Mac OS 9, which could only address that much.
I've also got to agree that it would probably be best to stick to the proper ram speed of your machine where possible, although Ive got a few PC100 systems with PC133 in them.
Other than that though, congrats on the QS! I'll admit that the QS has long been one of my favorite models of G4. (Even if it is really only a cosmetic update from the digiAudio [

To anyone who can help...
I just tried adding four 512MB PC2700 DDR 333MHz DIMMs in my PowerMac G4 (Mirrored) Dual 867 and it wouldn't start up (recognize them). I'm under, or was under, the impression that the PC2700 can ride on this model of Mac.
On the Apple support page it says for the 133 MHz system bus model (The one I have) that, "When only PC2700 or a Mix of PC2700 and PC2100 DIMMS is installed the computer starts up normally and behaves as though PC2100 DIMMs are installed."
So after reading that I took out one of the new DIMMs and added back my original PC2100s and it started up but apparently in and from The About This MAC I still only have my original PC2100 with three empty slots.
So I ask, are the 512MB PC2700 DDR 333MHz DIMMs no good in my 133MHz model or am I doing something wrong? Can they be recognized or did I get the wrong model of Dimm? HELP.
I also got an IOGear Hi-Speed 5-Port USB 2.0 PCI Card and I can't really tell if it's working in the sense of 2.0. I mean it working on the iPod I connected but it could be rolling on 1.1, no? How do I confirm this?
When I mention the About This Mac info, does that change with the ading and removing of devices and or what not or does it stay as is from stock? I would imagine it changes to show what is added or removed right?
Sorry for the rookie questions but when it comes to this stuff like adding memory or what not I am, BIG TIME.
Any quick answers will be greatly appreciated.

The big problem with newer faster speed memory in older machines seems to be the density of the RAM. I have tried some PC133 in my B&Ws and some doesn't work at all, some shows up as half of what it should be, and some works just fine.
Quicksilvers looks nice, but I think I like the less glitzy DA's more. Someday I will have the last OS 9.1 native booting G4 made (when they are freecycle finds probably).
2GB of RAM is decent even today, its nice to be able to stuff that much into older systems.

I was told today by the tech that I should try inserting one PC2700 512 Dimm at a time. They say they're backwards compatible.
So there you go, otherwise it's back to the shop for them.
f it, they, work(s), next on the agenda is finding out if the IOGear 2.0 USB PCI card is running at 2.0 or 1.1 because I couldn't find it in the profiler even though it was accepting an iPod. and apparently running faster than it was in the USB 1.1 slots.
Mac no matter how you look at it is DOPE.

Actually, according to mactracker, it says the limit on the QS was 1.5gb. Oddly, the sawtooth, and gig ethernet models could do 2.0gb under OS X, or 1.5gb under OS 9. Then, starting with the cube, and continuing through the DA and QS series, the limit is 1.5gb. then the MDD brought back the 2gb ceiling. Unless the app is wrong. I wonder why they took it out...and I wonder if you dual boot 9 and X on those rigs if you can leave in the full 2 gigs and just have the last 512mb ignored under 9...For what it's worth the physical ram ceiling of a QuickSilver is actually 2 gigs, and OS X can address and use that much, the stated limit of 1.5 gigs was for the benefit of Mac OS 9, which could only address that much.

I noticed that my former Cube and this QS have only 3 RAM slots; I haven't had any MDDs, but I'm guessing they have 4 slots, each with a max. capacity of 512MB. That would explain the 1.5GB limit on the QS and Cube (and possibly others).Actually, according to mactracker, it says the limit on the QS was 1.5gb.
