Fit Dual 450 mother board in 400 AGP?

Hi I want to fit a Dual 450 mother board into a AGP 400 mhz, I have noticed that the 450 Mother board has a twenty two pin connector and the 400 only a twenty hole connector.
The connector physically fits the socket via the guide slot but leaves the two first holes empty.
I presume these are the logic board feeds, can they be "jumped", if so from which pin to which pin?
Thanks in advance
Robert

Hi-
There are a couple of differences besides the number of pins. There is also a 28v feed in the GE. The problem in the conversion is the 28v. The Sawtooth PSU has no provisions for providing such.
You can get a 24 pin adapter at a PC store, and mod the wiring to convert the 20 to the 22 pin scheme, and then you can add a 28v "wall wart" to provide the 28v feed.
Using the G4 Pinouts as a guide, you should be able to get your wiring revamped. The author from outofspec adds some comments regarding using the external 28v power supply.
A 24 pin Motherboard connector example can be seen, as well as some other advice is available.
Other options are to simply get a GE PSU and put in the Sawtooth case, or get an Aftermarket PSUthat has the necessary wiring.
When I added an ATX PSU to my Sawtooth, I first modded a 20pin-24 pin adapter, made a few tests, and then modded the cable of the PSU. The adapter was way too bulky, but did allow me to build confidence in the proceedure.
One other bit of advice, is to *+triple check all of your work+*, so that disaster can be averted.

Processor from Dual 450 Gigaethernet to 400 single AGP Graphics compatabil

Can I put the duel 450 processors into single 400 mhz 100bus AGP Graphics G4?
I have another older and smaller mac and want to know if, after uprading my Giga-ethernet G4 (100mhz bus) whether the processors from it can be fitted to the AGP Graphics machine?
It has 1.12 gb ram
Machine model is Powermac 3.1
CPU type is Powerpc G4 (2.6)
20 gig hard drive
Any ideas?

Hi
I guess one option may be to upgrade the processor in the AGP Graphics machine instead. You could always swap some RAM and the hard drives etc between the two to make it your 'main' computer. As far as I'm aware the only advantages of the Gigabit Ethernet (other than gigabit ethernet and the fact they're slightly newer) are that some models came with dual processors and I think it also supports graphics cards with an ADC connector (unlike the AGP Graphics).

ATI/Radeon 9800 Pro 128 AGP 4x/2x in Gigabit Ethernet dual 450 PMac G4

Hi,
This is my first time posting to these discussion group... I've been going through related threads and have not found an answer to my problem...
I have a Gigabit Ethernet dual 450 G4. Awhile ago I upgraded the processor to a Sonnet 1.8ghz so I could run Leopard.
I just bough the ATI/Radeon 9800 Pro 128 AGP 4x/2x video card. I researched around and that seemed to be a card that would work in my machine. I even read a review on Amazon where someone had also upgraded to the 1.8 processor used this card with no issues.
I do have an older monitor - Apple Studio Display CRT with the ADC connector. So I also bought the Apple DVI to ADC adapter kit.
I installed the card and do not get any picture at all - I believe I have installed everything correctly. I'm pretty sure I can hear the fan on the video card in the machine. The monitor is getting power from the adapter since the button lights up when I press it - but it does not stay lit -- the monitor never turns on. Using my old graphics card the monitor makes a little "beep" when it turns on.
In reading the other topics I am wondering if it might be a power issue? According to Other World Computing's profile my machine has a max of 220 watts. Although they suggest this video card as one the will work in my machine.
I have disabled the hard drive that came with the machine (too small) and am using two Maxtor hard drives that I added - one ATA (120gb) and one SATA (500gb) that is connected to an SATA pci card. I also have two additional pci cards with usb 2.0/firewire ports.
In looking at the topics here I came across the link about taping the 3 and 11 pins on the video card. Even though the card I have is 4x/2x not 8x I thought I'd give it a shot. That did not work either.
Any help you can give would be greatly appreciated.

I don't wish to sound redundant here, but I've been reviewing the vendor's page:
It's OK- I don't mind beating this dead horse....
The maker says such to protect themselves from possible claims that may arise due to over loaded systems and power problems when their card is installed in said system.
Of course, 300w would be nice, but they didn't even specify the PSU rating a couple years ago. The Sawtooth, with it's 237w PSU, used to be listed as a compatible machine for the 9800...... They just didn't consider how far a Sawtooth might be modded.
Within reason, the early G4's (Sawtooths) are capable of using the Radeon 9800 Pro. The GE has the same 338w PSU as the DA (they are interchangeable), so there is plenty of power for the 9800.
One thing to remember, the requirements of the ADC port of the AGP slot are removed by using a non ADC card. This really changes the calculations of the power available.
It's kinda' a long post, but, if you care to get ALL the details, check the following:
http://discussions.apple.com/thread.jspa?messageID=7065653&#7065653
I think you'll be satisfied with the explanation.......
Which leaves your second, and very appropriate, point.
The main enemy of all, though, isn't power. Heat is the biggest concern.
Reducing heat/increasing cooling by using a third party fan on the 9800 is highly recommended. The 9800 is a hot card, and the stock fan is prone to early failure.
Adding additional cooling to remove the extra heat produced by the 9800, by using an exausting PCI fan, will also help the PSU provide adequate voltage to the system, by reducing the amount of hot air moving out of the PSU.
Super heated air moving through the PSU reduces the cooling ability of the PSU. A hot PSU doesn't produce reliable power.
So, add the 9800, add some cooling, and enjoy!

Can G5 1.8 dual mother board replace by a 2.5 dual

I've got a g5 2.5 dual mother replace to a 1.8 dual g5 tower, nothing happen except all the fans, did anyone know is it work, or my 2.5 mother board also dead?

2.5 dual mother replace to a 1.8 dual g5 tower, nothing happen except all the fans
FSB is completely different between the dual 1.8 and dual 2.5 GHz processors of the 970FX series....900 MHz vs 1.25 GHz. That likely isn't going to work as it is a big overclock.
Also, if the 1.8 processors are 970 series processors, I doubt that they would work on a 970FX board, which the 2.5 GHz board is..

Help me locate mother board-AGP G4, battery please!

My zapping the PRAM didn't help. I need to remove the mother board battery for that case. I check but do not know where the battery is loacted on the MB. I have the 1999 AGP 500MHZ G4 MAC.
Please help!

Hello! Yes the battery probably needs changing as 5 years is the max for one. I don't change one very often myself but then again I never shutdown my computer (very rarely) and it doesn't tend to run one down unless it's shutdown and unplugged. Always glad to help. Tom
You can pick one up on eBay or a Radio Shack Store.

Swapping mother boards

Since my 450 MHz video board died, I have parts I can use in other iMacs. I have one at work that the ethernet port was zapped.
Can I put a 450 MHz mother board in an older 400 MHz SE machine?
Thanks

Take a look back at your other topic. I suggested you try pressing the PMU reset button on the motherboard, before giving up...
Actually, I'll just copy/paste the info here:
One last thing to try before you take it apart.
Try resetting the PMU. It's like resetting the PRAM, but more extreme. Sometimes it works, if the problem is not the video board. I think it may not be the video board, because that problem usually starts with periodic shutdowns and the "snapping" sound before it gets to a point of not starting at all.
I found this web page with clear instructions. Pay attention to the part about not pressing it more than once.

G4 Dual 450 Boot Problem

Ive been reading other issues that others have been having. Ive got a 450 agp that I upgraded to a dual 450. I hadnt used it in a while and when I tried using it again, it would cut on, but no video, startup sound or light on button. Before I read the help column, I ordered another processor and heatsink thinking that was the problem. I installed the new processor and the cpu would start but had some issues. So I took everything off to test the other motherboard and when I re-hook up the new board; Nothing happened. The no light on power, no sound or video issue happens.
Ive looked up and performed the reset cuda, pram process numerous times for nothing to happen. I even bought a new battery, and stripped the motherboard down to nothing; waited 30 minutes and followed the reinstall procedure given and still nothing. Now maybe once is ok, but 2 motherboards and 2 processor is unlikely. Anyone experienced similar and can help???

Hi-
To be clear, what model motherboard are you using?
What CPU are you trying to use?
Have you tested the PSU (power supply) for power?

Mac Mini Core Duo 1.83 vs. Dual 450 G4

So I know somebody selling a Mac Mini Core Duo 1.83 for $200. My current machine is a Dual 450 G4. Would the Mini be a faster machine? I know it seems like a stupid question, but the Mini has been maligned because of its Integrated Graphics (my g4 450 dualie has a Radeon 8500 with 64 megs dedicated). I mostly use my machine for Photoshop, Indesign, music production and light video work.
I'd have to bump up the Mini's ram (it's only got 512 mb); my g4 has 1.75gigs of ram. Other than hat, would the Mini seem like a faster machine?
Opinions?

VRAM≠more performance.
I didn't say it did.
Integrated graphics steal from the main system memory and resources, so they shouldn't be considered when doing amateur or professional editing software.
It's true that on-board graphics use main RAM, thus removing 64Mb of memory from availability to the system, but out of a total of 2Gb, or potentially 3.3Gb on a C2D model, that is hardly a factor. It must also be said that while dedicated VRAM is a better bet for absolute performance, sharing high speed main RAM is also rather better than much slower VRAM on dedicated video cards such as the 8500 mentioned previously.
As to whether the presence of shared RAM rather than dedicated RAM should exclude a system from consideration when doing 'amateur or professional editing', I'd say that depends on the user, and that user's genuine need. Nothing, in the world of purchasing decisions, should be excluded until it is known to be unsuited for any of the reasons an individual might have. Given there would appear to be many people using Mac minis for tasks including video and image editing (including myself), it would seem clear that at some level these systems are perfectly suited to the task.
His Dual G4 has 1.7GB of RAM, a lot more than what the mini has—512MB.
Current Mac minis don't come with 512Mb RAM, and can be expanded to 4Gb (of which 3.3 is usable to the system).
The only category in which the mini wins is in CPU.
Actually not. Just about everything in a Mac mini is faster, not least bus and RAM speed. The only aspect in which there is parity is in the 5400rpm internal drive that both systems come with as standard.
That is not to say the G4 doesn't have advantages, as I have mentioned before it. It is far more expandable, with additional internal drive bays and where it is almost child's play to fit a fast internal, a better burner, more RAM an Airport card (though 802.11b only of course, not 802.11g) and even replace the CPU. The G4 is a true (and venerable) workhorse. Mine is still in service after almost 10 years and remains a favorite 'go to' system. What it is not, however, is fast.
Isn't it kind of obvious that if the person is using the Dual G4 for editing, he has PPC versions that run fast on his machine? That brings up another thing: If he were to use the software on his Dual G4 on a Mac mini, there'd be no benefits because, as you know, it'll run on Rosetta, which means that it'll run a lot slower than an Intel Application because it's being emulated.
Actually, as long as there is sufficient RAM, PPC apps will run as well, or faster, on an Intel system of sufficient speed differential, and your argument pre-supposes that the user is based on dated versions of applications which are not Intel-native, or cannot be readily up/cross-graded. At some point, a serious user has to consider that, even if not planning on a new purchase, since systems fail and need to be replaced, even if not always planned. At least buying into the Intel platform ensures forward compatibility and the ability to plan for future needs. To me, that's a critical part of using any system for anything other than simple pleasure.
Anyway, I have no intention to debate you on this - merely counter the point of view you expressed, which I believe to be somewhat misleading, and which directly counters my practical experience of running these applications on systems based on the same architectures the OP was discussing as options. As such, I remain certain that in every practical respect, excepting hard drive data access speed where the DP 450 has at least the ready ability to use 7200rpm internals, an Intel mini will outperform the G4 system in these broad uses. In my experience, the difference is notable.
Since the OP has your view, and mine, he or she is able to make an informed choice.

Pavillion DV4 mother board replacement

My Pavillion dv4 VM298UA won't charge. I tried a new battery, charger and DC jack but no luck. After searching the forums it looks like I need to replace my mother board. Does anyone have answers to the following questions?
1. What causes a mother board to go bad like this?
2. If I replace it is there anything I can do to prevent this from happening again?
3. I have seen new and refurbished boards avaliable with the refurbished ones being about half the cost of new. Is it ok to use a refurbished one? The benefit is lower cost, but what is the risk?
4. Is there anything else that needs to be replaced at the same time? ie fan, heat sink, etc
5. The boards I have seen do not come with a processor. Is it a big deal to take the processor off my existing board and transfer it to the new board? Any special tools or techniques needed?
6. How likely is it that the mother board is the problem and not something else? Is there any way to look at the mother board and tell? Any tests that could be done?
7. Anything else I should be aware of before I invest any more $ into this thing?
Thinking about this another way, with the hard drive from this computer fit into any other computer? I really would like to reserect the computer, but wjhat I really need to do is to get some stuff off the hard drive. Is there another compure I could get that I could plug this HD into?
Are there any post that address these issues that I just haven't found yet?
Any help would be appreciated.

Currnetly runnin OS X - not concerned with needing OS 9

Hi, J2, and welcome to the Discussions!
Your Mac's native drive bus will only recognize the first 128GB of formatted space on any size drive you install on the ribbon cable connected to the logic board, so look for a 120GB or smaller drive if you don't intend to purchase and install a PCI card to overcome this size limitation.
If you intend to connect the drive directly to the built-in bus as above, look for a 3.5 inch ATA (not SATA or SCSI) drive which runs at 7200 RPM, preferably with an 8MB buffer, versus a 2MB buffer, which is somewhat slower.
An ATA drive might be described as Ultra-ATA 133, IDE, EIDE, ATA 100, PATA, or parallel ATA. For shopping purposes, all of these terms basically refer to the same thing, so don't let them confuse you.
The major brands are Seagate, Maxtor, Western Digital, and Hitachi/IBM. Any of these brands should serve you well and you might shop online for the best "deal" by comparing cost/GB. Sales are common and often change from week to week, particularly amongst the mass merchants like Best Buy, Circuit City, Fry 's (outpost.com), Tiger Direct, Newegg, CompUSA, etc., so it pays to shop around online if you want to save some money. The best deals include a rebate or rebates.
Regarding OS 9, even though you don't intend to use it, when you do format the drive, I'd recommend checking the box in Disk Utility to install the OS 9 drivers anyway, which doesn't take up any usable space on the drive and might come in handy in the future, in case you need to update firmware or perform other tasks which OS X can't handle.

DV6000 faulty mother board

soon after buying my $1500 DV6000, my wireless card went out.
Then my hard disk failed.
Now not even two years oldthe mother board went out and I am out of warranty
The lap top used to get so hot, I could not touch the bottom of it.
Either the DV6000 is a bad design or I had a lemon. In either case HP should not ask for $400 to fix the issue.
This was the last time I spent money on HP products... no more

lol in that case we are 2 already, no more HP/Compaq products

Apple Hardware Test : mother board problem : post/16/64

I'm having this problem since last month. My computer won't boot properly, aligning lines and lines on the screen saying there's a problem with cpu 1 or cpu 0. I reset all Xram I could find, reset the PMU, changed the battery...
Finally, I used Apple Hardware Test that gave me this message : post/16/64 on mother board at startup. Then, when I run the tests, everything's OK !
I manage to boot from time to time with 10.4.7 only, other installed systems won't do it.
Would anybody have a clue about this ?
Thanks for reading me.
My computer is 4 years old, it worked well until then, I want it back, fully fitted.
I have screen shots that I can share if needed.

G4 QuickSilver bipro 1Ghz Ram 1Go Mac OS X (10.4.7) + Mac Os 9.2.2 + Mac OsX 10.2.x

Hi,
I have some good news for you all : I finally decided to open my machine and see what's inside...
I took a small paint brush, a screwdriver, a pressurized air bomb (hope you call it this way) and cleaned all the inside. I had some parts taken off, even the big thing that gets heat from the processors. My brother, who knows more than I do about the subject even advised me to unplug the processors, supposedly connected on a ZIF card (Zero Insertion Force card). I didn't manage to make them move at all. I took memory bars away, the video card too, to make place for the screwdriver to unlock the (radiator ?). Then I brushed all the dirt away, there was plenty, and put everything back inside.
It works fine, it really does. So, I guess and hope this will last for an other 4 years.
Thanks for the help.
Jacques.

Hot Rod PMacG4 400 AGP/Photographer

I read that onnly 1.5 GB of memory is allowable on the Apple G4 M7891LL/A. I have enough slots for 2 GB. What's up with that?
If I put 2 GB in it, will it do anything?
Also... So, my 9 year old Mac is getting slow, and can hardly handle video files, and I want a flat screen monitor (still have the old school box).
I was going to add another 512 of memory in the last empty slot,
and is it possible to switch out the Rage 128 Pro with 16 mb for a Radeon with 32 mb? If I do that, will it make a difference? What monitor could I hook up to ol' Macbessie then? I do a lot of Photoshop/photography work. It's come to a screatching halt because my discs are full, etc...
I'm also having a hard time viewing video at a resonable pace.
I don't want to buy memory, and a new graphics card, and then find out that I still can't support a decent monitor, and vise versa.
I just don't have credit for a new mac.
What there any other photographers on the Mac G4 400 AGP that have their systems Hotrodded? What did you do? HELP ME PLEASE!

Sandidt, welcome to Apple Discussions.
Here's the specs on your G4 Gigabit model http://www.everymac.com/systems/apple/powermacg4/stats/powermac_g4_4002.html
The max 1.5GB RAM only applies to operation on OS 9. In OS X, 2GB is the max. You might obtain a slight speedup with more RAM, however, you Mac is limited by the 400MHz processor speed & 100MHz bus speed.
Someone else will have to address the video upgrade. Rather than spend $ on upgrading your old Mac, you might be better off buying a newer, but used Mac. In the Dallas area Craig's List, G4 1.25MHZ Macs are listed for $325-400.
