Dual 800MHz in 733MHz QuickSilver - heatsink

Hello everyone!
I just had a PowerMac G4 QuickSilver 2001 (the original model) with a 733MHz single CPU from a good friend.
I want to upgrade the CPU and I already know that the CPU from the Dual 800MHz Quicksilver will fit and work in my computer, but my question is about the heatsink.
The Dual 800MHz CPU I saw on eBay doesn't come with an heatsink, so: can I use my heatsink from the single 733MHz with the Dual 800MHz or will it overheat? I could put a second 60mm fan attached to the heatsink to improve the airflow, will it be enough cooling?
Thanks!

As BD says, the 344W should be sufficient. It was standard on the 2001 Quicksilver with the dual 800MHz CPU.
I would worry more about the heat created. When I fit a dual processor to a Quicksilver, I fit an Evercool EC6025H12CA fan in place of the standard CPU fan. Cools things down nicely. It's a three wire fan, so you fold the third (blue, I think) wire out of the way. As I recall, you pull the blue wire out of the little white plug (folding it back out of the way) and move the black wire from its initial position to the space left when you pulled the blue wire. This lets you slide the little three wire plug onto the two posts of the motherboard where the original low speed fan went. The new fan will run at full speed (like the original) instead of being a variable speed job, but I haven't had one fail yet. Stare at it for a few minutes to get it all properly arranged in your mind, and it should go smoothly.
If you can't find a proper heatsink, you can try looking for a dual 1GHz CPU (and heatsink) from the 2002 Quicksilver. Interchanges easily.
I sort of prefer a Radeon 9800 or a GeForce 6800GT to the 9600, but anything should be faster than the GeForce2.
Best of luck! ... jws

Running dual processor on early Quicksilver board

I'm back to a Sawtooth because my 1ghz dual processor is panicking. Diagnostic in Tiger says the external cache is bad and I understand that I have to shut the cache off every time I boot by if I use CHUD to disable the L3 cache ( which I am very scared to do).
Because I'm more a MacButcher, I figure that running the dual processor on an earlier (733mhz) board which doesn't have the rom to enable the L3 cache might be a possible workaround. I'd then swap motherboards and run the dual limping a little on the earlier motherboard and slip the 733mhz processor in the later board and resell.
Does this all sound possible? What should I watch for? I realize the dual processor would run slower than intended, but it would be better than using the 500mhz Sawtooth and cheaper than buying a new processor.

Hi
I could be wrong, but I thought the level 3 cache was only not recognised if you installed a Quicksilver processor card in a Sawtooth or Gigabit Ethernet logic board, as these originally came with G4 variants that didn't have any level 3 (just level 1 on the processor die and level 2 on the processor card). If the 733MHz logic board is from a Digital Audio or Quicksilver, I wouldn't be surprised if the level 3 cache was recognised, as these shipped with G4 variants that could support level 3 (regardless of whether Apple actually chose to provide the extra cache on some of the models). I'd be surprised if there were any boot ROM differences - I'd imagine it just says if there's level 3 cache available then use it. That way Apple could have one unified logic board/boot ROM and just drop in different processor cards with or without level 3 cache. There are some reports in the CPU Upgrades database at xlr8yourmac.com which seem to suggest a 733MHz Quicksilver can be upgraded with a card pulled from another QS and the level 3 will be recognised.

Upgrading G4 dual 800MHz 10.3

fairly new to the Mac world, I have a system that I got for cheap it originally had a password set and it was lost. I called and got the original OS X 10.3 discs sent to me and reinstalled. It's a Power Mac G4 dual 800MHz PPC Quicksilver and I was wondering about upgrading it to 10.4 from 10.3. I found a retail set of 10.4 will I be able to upgrade from those discs keeping the applications already installed on the system or will I loose those and if the retail set is not the discs I need which ones do I need and what exactly do I need to look for?

aa-r0n:
if there is a link that will explain how to back the 10.3.9 up
To backup/clone the entire volume you will need an external firewire HDD and a backup utility like SuperDuper or Carbon Copy Cloner, or Disk Utility.
Creating a bootable clone with OS X Disk Utility
Clone HDD to external HDD using SuperDuper
• Connect external HDD to computer
• Power up HDD
• Start up computer
• Download and launch SuperDuper
• In the Copy field select your internal HDD
• To is your external HDD which will hold the backup/cone
• Using backup all files
• Click Options button
• Check Repair Disk Permissions on Source
• During copy Erase Destination HDD then copy from Source
• On successful completion Quit SuperDuper
• Click Copy and confirm
SuperDuper will take care of the rest.

Leopard Server on Dual 800MHz G4?

Sorry if this is a repost, I tried searching around for a while and couldn't find an answer to this...
I'm looking to install OS X Server on an old dual 800MHz G4 tower. I was just wondering if the install would allow it, because the clock speeds are below the minimum requirement, even though it's got 2 of them.
Thanks in advance,
J

No, Leopard's CPU speed restriction applies to a single processor. Your computer does not meet the requirement. You could look for a CPU upgrade for your model (check sonnettech.com) but you should know that Apple does not support CPU upgrades. Now that doesn't mean Leopard won't run on an upgraded machine, it means that if you have any problems with Leopard on an upgraded machine, Apple provides no support and does not guarantee that Leopard will work on an upgraded machine. However, the vendors selling the upgrades can confirm compatibility (at least with Leopard Client. I don't know if they test the Server version.)
You will need to weigh the differences between the cost of upgrading the computer versus buying a new or newer model with a faster processor.

Enable L3 cache on Dual 800mhz G4 processor

can anyone help?
i cannot enable the L3 cache on this processor.
im am not sure if it is even working or present
CPUD shows no option to enable it
it does not show in the system profile
Reggie SE show me an error (1018) when i try to enable the L3 cache.
i have tried to use the .kext written by Till Wimmer but i get an error on reboot saying the .kext file was not properly installed.
i am not so sure about using terminal
any help much appreciated

hi thanks for the replies,
As far as i am aware the specs show that the Dual 800mhz processor does have an L3 cache, and yes it is from a QS, modded into my DA.
the L3enabler is mounted when i am installing the .kext file.
i am a little unsure with Terminal, i am not sure that i am inputting the commands correctly, i am basically cut+paste the instructions with L3enabler
please correct me if i am doing the totally wrong thing!
step by step instructions would be great, spoon feeding if you like, whilst i cn get my head around the installation of hardware, my knowledge of programming code is VERY limited
(Cracking code for my ZX spectrum in the 80s was easy but i missed out on unix lessons!)

Will a 800mhz dual work with my QuickSilver

Hi i have a Quicksilver with a 733mhz processor, 768mb ram and mac OS 10.3.9 on a 160GB. I was wondering if my 733mhz can be replaced with a 800mhz Dual. Please HELP! Thanks!!!

Hi-
No electrical worries.
No jumpers, settings, nothing.
Use the same fan, and connect the fan to the same connector.
Watch this video:

Don't forget to put new thermal tape or thermal compound on the heatsink:

No Power Quicksilver Dual 800MHz...

My QS started acting strange last week - when I had to reboot I got a folder with a question mark icon. I rebooted several times and got the same thing. Then I unplugged the Mac and looked inside, cleaned up some dust, etc. Plugged it in and nothing - no light, no noise, nothing happens. Ah ha I thought, the battery on the motherboard is dead - the mac is something like 5 years old. So I picked up a new battery tonight, put it in the mac, zapped the PRAM and still nothing happens, not a sound or a light. Any suggestions on what is going on?
cheers,
Michael

You're right about the link you provided, Dave - the procedure is the same, the only difference is that the trickle voltage measured on a QS at pin 22 should be 25 volts, instead of the 28 volts shown for the Gigabit Ethernet Mac.
Regards,
Gary
ps to Michael: The procedure might look intimidating, but it's really quite easy! Here's a link to a color-coded pinout diagram, which helps to confirm the pins by the wire colors...

Dual 867MHz Is now Dual 800MHz After Motherboard Replacement?

so i replaced the motherboard on my dual 867MHz G4.
the computer turns on now, and i did a fresh 10.4.11 install...but i noticed that it says "Dual 800" instead of "Dual 867" in my "About This Mac" now. i typed "sysctl hw.cpufrequency" in the terminal and discovered that it is actually running at 800MHz, and not 867MHz.
so why did i lose 67MHz with a new motherboard? it was the correct motherboard...any ideas?

G4 MDD Processor and bus speeds
There are two classes of Processors for the Mirrored Drive Doors G4 Macs, and they do not follow the main distinction between the products -- Firewire 400 Vs. Firewire 800.
In the Mirrored Drive Doors models, processor speed is determined by a combination of the jumpers on the processor modules and the Bus Speed of the system into which the processor is installed.
• Install a processor intended for a faster Bus speed into a system with a slower Bus speed, and it will be clocked slower and run slower than expected. 133/167 slower.
• Install a processor intended for a slower bus speed into a system with a faster Bus speed, and it will be clocked faster -- in most cases so fast that it will immediately crash.
133 MHz Bus speed:
867 MHz dual w 1 MB cache (each processor) from Fw 400 model
1.0 GHz single w 1 MB cache from Fw 800 model
167 MHz Bus speed:
1.0 GHz dual w 1 MB cache (each processor) from Fw 400 model
1.25 GHz dual w 2 MB cache (each processor) from Fw 400 model
1.25 GHz dual w 1 MB cache (each processor) from Fw 800 model
1.42 GHz dual w 2 MB cache (each processor) from Fw 800 model
1.25 GHz single w 1 MB cache from "education only" 2003 model

I have a Dual 800 G4 and am trying to set it up so I can use the Migration Assistant on my new MacPro. When I try and restart holding down 'T' the computer just abruptly shuts down.

Power Supply on MDD Dual 1G Same as Quicksilver?

Can anybody tell me if the power supplys are interchangeable.
Thanks

Hi-
No, they are not.
MDD's only work with MDD PSU's.

G4 QUICKSILVER 733MHZ TO DUAL-1GHZ

#1 Will the QS dual 1-ghz card work in a 733mhz quicksilver server model with no change to the system board? can i just put the dual 1ghz in the 733mhz QS?
#2 Will the 64mb video-card from the QS Dual 1ghz work in the 733QS with a 32mb video-card now? and can i just put it in and will it work with no new drivers or jumpers?
#3 will all of that overload the QS 733mhz psu? i just found a 733QS server for $95 i think i over paid for it but i con not find a psu for the dual 1-ghz so i bought a qs 733mhz because i did not know if it was the psu or system board i know i can put the psu in the qs 733mhz in the dual 1-ghz but i do not know if the system board blow the psu? and i do not have any more $ for computers or parts. or wood it be better off just to leave the 733mhz qs alone? i do want to run leopard and ilife '09 on it but if something goes bad i will not have any qs so i can live with just leopard or tirger if i can use LeopardAssis app does it work in a qs? but i wood like to use the dual-1ghz in the qs 733 so i can use ilife'09 and not have to use a 3-party app to install leopard.
#4 i have a old post but i needed a new topic so i made a new post so it is easyer https://discussions.apple.com/thread/3071835
By-The-Way thank you japamac for all your help

Well i put the dual 1ghz in the 733 qs. and it blown the psu i guess the cpu is bad i just put out anouther $50+ for a new psu but when i put the 733mhz qs cpu back in i forgot to put the fan and the heat sink back on the cpu still works i puled the plug very quick. but the thermal paste is now gone on it i will get new thermal paste for it. do i just put the thermal paste ontop of the cpu top or on the heat sink? but the video card works very good from the dual 1ghz in the 733mhz qs

Yes.
You just need the dual processor heatsink.
Will the 64mb video-card from the QS Dual 1ghz work in the 733QS with a 32mb video-card now? and can i just put it in and will it work with no new drivers or jumpers?
Yes.
Plug and Play.
will all of that overload the QS 733mhz psu?
No.
No worries at all.

Dual Displays G4 Quicksilver

hello everyone,
i just got an AOC (DVI) 17inch flat panel display. I got an ADC to DVI adapter and hooked up the new AOC monitor. A Sharp flat panel monitor is connected to the VGA port. I have three problems.
1.) When the Mac starts up, the AOC monitor displays the white apple screen distorted everytime in new fasions upon each restart after the white apple screen, everything is perfect. Is this a problem/common?
2.) My new AOC screen is much brighter than the Sharp screen, is this to be expected?
3.) On the Sharp screen, instead of a mouse cursor, i get a white box that moves as the mouse but on the AOC screen, i get the mouse cursor, how can i fix this.
P.S. how do i span the two screens?
Thanx a million
Vince

Hi
In System Preferences - Displays there should be an arrangement option so you can choose which of the two displays is the main one and an option to switch mirroring on or off. These will only be present if your graphics card supports two independent displays. I believe the dual 800MHz Quicksilver had a 'TwinView' graphics card capable of supporting two, which allows the desktop to be extended across both, whereas the stock graphics cards in the 733MHz and 867MHz models only supported one (you could connect two to the card, but the desktop on one would simply be mirrored on the other).
I think some variation in brightness between flat panel displays is normal, even if they're the same model from the same manufacturer. If they're from different manufacturers and use different LCD panels, back lights and/or electronics, I guess the difference is likely to be more pronounced. I believe the brightness of the back light can also reduce with age, and the display brightness may also depend on whether it's connected via the VGA or ADC/DVI port.
I hope this answers a couple of your questions.

Dual 800 quicksilver AGP card

hi all,
Yesterday I picked up an old quicksilver G4 with the dual 800mhz cpus. i tried to install a nvidia geforce 6200 AGP that I have in my PC. it fit, but it was tight. I put the mac together and it would not power on, or even light up. I know the card works because it works great in my pc. I put the origanal card in the mac and it booted up like normal. I noticed that it's cmos battery is dead, could that effect it? I will use this mac more than the PC if i could get that card to work.
- Thanks in advanced.

I pretty well covered all the "how to" bases in my post above......
Here is a NVFlash how to:
http://themacelite.wikidot.com/nvflash-basics
The linked description page for the 6200 WANG also has the downloads link to the ROM page.
As for that particular card, well, there is a bit of the unknown, but it appears to be a reference design which simplifies things.
One may need to do some identifier editing in the ROM.
It's a "flash and see" kind of thing.
Might make an account at Strangedogs to access the Pro boards and see what others are doing for 6200's.

G4 QuickSilver 2002 Dual Drawer With 2-DVDs Needed--Slot 1 & Slot 2

Guys/Gals:
I have a dual door G-4 QuickSilver (2002) with a new Pioneer 110D drive in the upper Slot 1. Below that in Slot 2 is an empty 3.5" "Zip" drive housing.
I there a way to remove the present 5.25 inch housing and 3.5 inch zip housing and replace it with a mirrored door housing--or an aftermarket 5.25 inch housing so I can put the old DVD-RW-104 Pioneer drive in Slot 2 and keep my new Pioneer 16 x DVD drive in Slot 1.
I would gladly remove the front panel--providing it is not prohibitive-- if that is necessary and the replace present 5.25" housing. I would prefer to use the second slot in the QuickSilver as I have some desk space issues.
I saw on the Apple site that the mirrored door QuickSilvers have two 5.25" Drives-- one under the upper drive with a single housing.
http://www.info.apple.com/usen/cip/pdf/g4mdd/g4mdd-opdrive.pdf
I wonder wil this approach work--and will it be worth it.
Any other suggestions or resolutions to my issue.

POWER MAC G-4 (933 MHz QuickSilver) Mac OS X (10.4.5) iSite

Although not quite as involved as THIS, modding a QS case still involves cutting the sheet metal front casing, and modifiying the drive mounting case to accept a full-size drive.
It can be done, as the processor/heatsink is not in the way, as is the case with pre-Digital Audio G4's.
You will need ARDIEM to re-map a function key to eject the drive, as Apple's Option-Eject on works with MoBo's (MDD G4) that natively support two full-size optical drives.
xlr8yourmac.com used to have a link to a QS mod, but it has been dead for years now. elroyonline.com modded his QS G4, but never posted the photos online. You could drop him an email.

Dual 1.25 Ghz processor swap into 867 quicksilver?

Hey… I know this is going to sound like an odd question, BUT… I am considering upgrading my 867MHz Quicksilver processor, and tried a 1.5GHz upgrade chip from OWC. It didn't give me the performance boost I was hoping for. I have an opportunity to take the processor out of a dual 1.25GHz Mirror Drive Door PowerMac G4… is it possible to place the processor & heat sink from this machine in my older 867? I think the dual has a 167 bus vs my slower 133 bus, so I don't know if that's a problem. Thanks in advance for the help!

Hi
unfortunately processor cards from MDD G4s aren't compatible with Quicksilver (and earlier) G4s as they use slightly different architectures and possibly even different processor sockets. That's partly why OWC (and other third party) processor upgrades cover models from the AGP/Sawtooth G4s upto the Quicksilver 2002 G4s, but aren't compatible with the MDD or FW800 G4s.
The fastest 'Apple original part' upgrade would be a dual 1GHz from a Quicksilver 2002. I swapped my single 800MHz for a dual 1GHz (pulled from another Quicksilver) and the difference in performance was very worthwhile.
Having said that though, most benchmarks show a dual processor G4 is around 40% faster than a single processor running at the same clock speed, so I'm not sure a dual 1GHz would be much (if any) faster than a single 1.5GHz. Also which ever processor upgrade you choose, you're still stuck with the same relatively slow 133MHz system bus, which will impact real world performance.
I hope this helps.
