will DA processor fit in Gigabit?

2010-08-06 Thread Geke
I just got a Gigabit with a Sonnet Encore ST/G4 1GHz processor upgrade
inside.
Now I want to swap that Sonnet with the 466MHz cpu in my Digital
Audio, but before I do that, I wanted to check two things here:

1. How tricky is it to put the DA's CPU into the Gigabit? The CPU is
the same, but I read that the location of the CPU card on machines
previous to the digital audio would require some modifications to the
motherboard/case.
(The other way I can manage; I have the Sonnet instructions for
putting in the Encore.)

2. What do I gain by this swap? I mean, the DA is a bit newer and
faster, but is it worth it, or should I just switch to the Gigabit?
- I have already tried the DA's video card in the Gigabit and it works
OK; does it make a big difference that the DA is AGPx4 and the Gigabit
AGPx2?
- The RAM in both computers is PC-133
- Does the slower ATA bus speed of the Gigabit make a big difference
in actual practice?

Thanks in advance for your views!

2 Main considerations.

1) I think with the DA Card (I know with a QS card) you have to  
remove one of the 2 IDE connectors on the motherboard to get it to  
fit. We are talking board level soldering.


2) The DA has a 133MHz bus speed and the gigabit has a 100MHz. The  
466 has a 3.5 x multiplier so if you do the work above you will

only have a 350MHz machine.


2. What do I gain by this swap? I mean, the DA is a bit newer and
faster, but is it worth it, or should I just switch to the Gigabit?


Between the faster bus speed and 4 x AGP, yes, switch.

- I have already tried the DA's video card in the Gigabit and it works
OK; does it make a big difference that the DA is AGPx4 and the Gigabit
AGPx2?


If the card can take advantage of it, yes it does.

- The RAM in both computers is PC-133


Good, it is swappable


- Does the slower ATA bus speed of the Gigabit make a big difference
in actual practice?


AFAIK, the ATA drive interfaces are the same. There is a faster  
motherboard bus speed on the DAs (133 vs 100) and that DOES make a  
difference.

I seem to remember someone saying, that the System Bus speed bump from  
100 to 133 was significant, but that after that (167?) folks didn't  
see much improvement on G4s.


www.barefeats.com might have some benchmarks ...

The Giga-Designs processor upgrades were designed from the outset to  
fit in either processor position: the old position as found in the  
Gigabit Ethernet G4s or the new position as found in the Digital  
Audio and Quicksilver G4s. Giga does this by having a two-position  
processor cooler, and an innovative board layout which accommodates  
the special need of the Gigabit Ethernet for access to its optical/ 
ZIP drive PATA channel.


The Giga-Designs processors were also designed for easy changes from  
a 100 MHz bus machine to a 133 MHz bus machine.


I don't know if Encore offers this same flexibility.

It can make a difference, but that difference is probably somewhere  
in the neighborhood of 150 minutes to do a complex DVD authoring/ 
mastering job on a Gigabit Ethernet (100 MHz bus, an slower ATA  
channel) to 120 minutes to do the same job on a Digital Audio or a  
Quicksilver (133 MHz bus and faster ATA channel).


In stark contrast, a Shuttle SP35 OSx86 Hackintosh can do that same  
DVD authoring/mastering job in 12 minutes ... a 10-to-1 improvement  
in wall-cock-time, which is certainly one important measure of  
performance.


I still retain 133 MHz bus G4s for ordinary work (such as web access  
and Mail.app access, for which a 133 MHz bus and a dual 1.0 GHz G4  
processor is certainly satisfactory).


All the heavy lifting in my shop is now run on OSx86 Hackintoshes  
with, variously, 800 MHz to 1600 MHz buses and dual or quad Intel  
processors in the very high 2 MHz to low 3 MHz range (Pentium Dual- 
Core E6700 3.2 GHz, but over-clockable to 3.8 GHz to Core 2 Quad  
Q9550 2.83 GHz, but over-clockable to 3.4 GHz; however, I rarely  
operate my processors over-clocked, preferring reliability over  
excessive stress on the various components).

Re: Yikes G4, Can The Computer Chime and still have a Bad CPU?

2010-08-06 Thread Gus
The Short Answer:  Yes a bad cpu can give you a good Power On Self
Test Chime.  What you do is keep downclocking the CPU till it
eventually gives you video and boots.  You may even have to go to the
lowest setting your motherboard allows before it does gives video and
boots.  If a CPU has been heat stressed in the past, it may say that
it is a 500 MHZ processor, but may work just long enough to pass the
P.O.S.T. and give a chime, and then lock up (at its 500 MHZ
settings).  Lower clock speed = less heat = more likely to boot.

(For the archive).

Thanks all that helped with this problem.

 Chime, But no video.    No turn over to open firmware.  (no cd boot,

 STRONGLY SUSPECT I HAVE A BAD CPU.

 BUT!!!  I am smart enough to know that I don't know everything.  Is

 For grins, I did drop the system clock from 400.. then up to 500  No

It's not just a matter of heat.  The chip may just not be able to run at 
a given speed regardless of how hot it gets doing it.


One suggestion, keep dropping the clock speed till it boots and works 
okay... then drop it one more.  You may be right on the edge of it 
working okay and any little thing could push it over such as temperature.

Yes, you do need to be more clear. I'm guessing you want to cut the  
wires from the power supply that go to one of the standard molex  
power jacks, and splice an SATA power cable in its place? If this is  
what you're asking about, my reply is: Use the cheapo adapter.  
You'll make a mess of splicing the wires


	Mess? a neat solder job and some shrink tubing? and that's assuming I  
have to cut the wires at all.


, and probably short out your power supply with some bonehead  
mistake. Use the adapter, that's what they're made for, they work. I  
use several in my older computers with no problems.




Kris, If I honestly thought this was more of a job than what I could  
do, I wouldn't attempt it in the first place After some research  
of my own, I found out that a simple push-down sata power connector  
can simply, and I mean simply replace the molex connectors... I  
ordered several to have a few extra for future projects.


Regardless, thanks for the advice. Jeff

Great! Since you know what you're doing, I'd suggest doing it without  
first posting to the list. In my opinion your rewiring job is make- 
work. The 99¢ or less adapter accomplishes identical functionality in  
a fraction of the time or effort.

the subject line comes from a mel brooks comedy. sorry if it  
looked like a slam on adapters. It wasn't meant that way. J

You'll find that Molex, and AMP too, recommend against soldering those crimp 
terminals. The high temperature and solder blobs interfere with the flexibility 
of the metal and the mating force of the connectors after assembly.  Use a 
crimp tool!

Re: Whatever happened to RAM disks?

 Anyone still work with them?  For what uses?  How?  Thanks.

 They are very much around and useful for those who know how.
Do you have enough RAM ? MAX it !

Want to speed up your Photoshop or other application ?

Make a RAM disk according to the OS help instructions online or from your
drive.

Copy the application and any source files to the RAM disk. The system treats
it like a physical drive.

Do your chore. Copy out the work to a physical medium often. In case the
system fails.

Because Application calls to itself in RAM disk are faster than calls to
mechanical hardware things work faster and smoother. you can set it up so it
appears on boot and also have the apps there too.

Want to browse the web but empty the cache files for good on shut down? Put
whatever browser caches or any other unwanted files into RAM disk. When you
shut down they are gone with anything else in RAM. No traces.
