G4 MDD (FW800) processor upgrade

Thinking about upgrading to dual 1.25 processor but curious about different bus
speeds. Apple specs list fsb for single 1Ghz processor at 133 MHz and for dual 1.25 processors at 167 MHz. Can't find p/n's to compare logic boards so is the bus
speed 'fixed' for a specific logic board, or is it changed automatically with a different processor, or do I need to do dip switch/jumper/hard wire changes? The processor I'm looking at on eBay says that it was pulled from a G4 MDD (not specifically from a FW800). I'm not even sure I want to do this since I haven't experienced any noise/overheating problems with the single processor.

I'm searching for information about how to change bus speed on a mdd fw800 with a single 1ghz cpu. How does one make the bus go from 133mhz to 167mhz ? I've seen the pictures on http://www.macbidouille.com/article.php?id=89&page=3 but the motherboard of my G4 does not look like this, at last from the component side.
Does anyone have information about how to switch a MDD G4 fw800 from 133mhz to 167mhz bus ? I'd like to upgrade the cpu in mine and i need new ram anyways so i'd like it to go full speed.

FW800 processor upgrade

Will a MDD 1.25Ghz CPU fit in a FW800 model that had also a dual 1.25Ghz CPU?
My old CPU is dead so i was looking for a new on ebay. Found one from a MDD and it had this number on the sticker: KC306USGP8GB*630T4530/630-4528.

Yes. (I love short answers!)
Check this page for the specs.

Can i put a MDD/FW800 processor in an AGP Powermac G4?

topic question says it all? is this possible?

Quick answer - NO.
Why not buy a MDD/FW 800? I've seen these on the Dallas area Craig's List for around $400 +/-.

FW 800 - processor upgrade?

Hi,
please tell, are there any processor upgrade cards for a PowerMac FW 800?
Thanks,
Alex

Hi Alexander-
"The Power Macintosh G4 (Firewire 800) series is similar to the "Mirrored Drive Doors" series that it replaced -both share an identical case, complete with "mirrored drive doors" and the same bus speeds (133 MHz or 167 MHz) and RAM (PC2100 and PC2700), for example -- but the "Firewire 800" models have faster optical drives and add a single Firewire 800 port along with support for onboard AirPort Extreme (802.11g) and Bluetooth 1.1.
Perhaps most notably, however, is that the "Mirrored Drive Doors" models are capable of booting in MacOS 9, whereas the "Firewire 800" models are not."
http://www.everymac.com/systems/apple/powermacg4/stats/powermac_g4_1.0mdd.html
Except for the OS 9 boot abilty, the models are so similar, that they are often grouped together under "MDD".
The link (in my 1st post) to the Sonnet processors is from OWC, a Mac upgrade specialist, who lists the MDX as a processor upgrade for the FW 800.
Also, MacUpgrades UK lists the MDX as an upgrade option for the FW 800:
http://www.macupgrades.co.uk/store/productinfo.php?productsid=281
I checked the xlr8yourmac database for user reports, and found one match in (criteria) G4 MDD/Sonnet. The report is from a FW 800 owner, who had a VERY unique problem:
http://forums.xlr8yourmac.com/cpureview.lasso
Mike, the editor, makes a very good point regarding the lack of L3 cache on the 7447 Sonnet processors. The lack of the L3 actually limits the overall "speed" of the processors, and the 7447 processors really aren't any faster than a 2x1.3ghz-1.4ghz 7455 processor with the L3 cache. In fact, for video, games and such, the L3 cache is an important feature in the G4's performance.
If I were looking for a processor for a FW800, I would consider a 2x1.42 ghz OEM processor, or the above linked GigaDesigns 7455 processor, before I would consider the quite expensive Sonnet (which also requires software patches, as the 7455 processors don't).
LowEnd mac also has some thoughts on this processor and upgrading the MDD, as opposed to moving to a G5. See "MDD Processor Upgrade vs. Used G5" on the linked page:
http://lowendmac.com/mail/07/0605.html
Finally, I intend to check with OWC support after they open in a little over an hour, and confirm their recommendation of the MDX for the FW 800. I will post back.

How Do You Identify Logic board revisions for MDD FW800?

I have a logicboard, the CPU board, and the heatsink for a PowerMac G4 MDD FW800 DP 1.25 that I want to sell, but I can't figure out what Revision it is (A, B, C) or if it is 133MHz or 167MHz. I do not have the computer (bought for parts) they came from anymore but I have my own MDD FW800 DP1.25 I could consult. Logic boards, I'm discovfering, don't make for easy reading--can anyone assist or point me to a "Logic Boards 101" text?

Hi-
The following should help to ID the logic board.
For the FW800 1 ghz board, the part is identified by looking at the serial # ON THE BOARD.
Look for one of the following code combinations in the
last 4 digits of the serial # : NME,P2X,P3E,P3G,P3U,P7P,P8E,
PFD,PFF,PFG,PFT
This would be the 133mhz model.
For FW800 multi processor boards, the part is identified by looking at the serial # ON THE BOARD.
Look for one of the following code combinations in the
last 4 digits of the serial # : NMF,P2Y,P3F,P3H,P3V,P7Q,P8F,
PFE,PFH,PFJ,PFU
This would be the 167mhz model.
For the MDD 167mhz, rev A, look for one of the following code combinations in the
last 4 digits of the serial # MXJ,ND0,ND9,NE2,NE8,NEV,NEX,NFA,NFG,
NG1,NKT,NNR, NNS,NNW,NRC,NWK,P8S,PG2,PG3,PG4,PG5,PG6,PGI
For the MDD 133mhz, rev B, look for one of the following code combinations in the
last 4 digits of the serial # : NF9,NG1,NNR,NRC,PG7
For the MDD 167mhz, rev. C, to determine which 167 MHz logic board is installed in the computer, check the AirPort Card connector at the edge of the board.
If there is a 2-pin fan connector on both sides of the AirPort Card
connector, it is rev.C. Otherwise use rev. A.
Look for one of the following code combinations in the
last 4 digits of the serial # :MXJ,ND0,ND9,NE2,NE8,NEV,NEX,
NFA,NFG,NG1,NKT,NNR,NNS,NNW,NRC,NWK,P8S,PG2,PG3,
PG4,PG5,PG6,PGI

New Sonnet Encore /MDX G4 processor upgrade?

I looking at New Sonnet Encore /MDX G4 processor upgrade.
http://www.sonnettech.com/product/encoremdxduet.html
Do you think that would make my Power Mac G4 MDD (if I got Dual PowerPC G4 7447A CPUs running at 1.8 GHz) about as fast as my iMac G5 1.8 or my MacBook 1.83 ?

My Dual 1.25 is just as fast as the iMac G5 1.8 it replaced.
Your MacBook beats all of these machines, it is a Dual-Core processor, and it's a newer chip that beats any PPC except the Dual G5's.

Processor upgrades

i have had a single 1ghz mdd firewire 800 for about a year. i had great plans for this machine but it is basically a print server for my g4 imac in the living room. recently i purchased a 400 mhz sawtooth to replace the mdd. Is downgrading from a mdd a good idea? i plan on selling one of the powermacs. if i decide to upgrade again which is easier/cheaper to upgrade? there are a lot more processor upgrades for g4 models earlier than the mdd and i am not sure why. i purchased the mdd for around $400. i purchased the sawtooth for $10.

My LW 16/600 will work with the Wintels if hooked via parallel or via ethernet reversed pair cable (single cable with one reversed pair). But if I hook the LW to a hub or to the router the only units that can see it are the Macs. I just turn on sharing on the Mac and make a printer profile in the Windoze control panel that routes to my mac (\\xxx.xxx.x.xxx\<mac name>\<OSX printer profile>). I imagine it has something to do with the protocols back in 1995 when the HP4 was being made as a LW.
But if you say that your HP5 will show up when hooked to a hub but not a router I may try that, isolate the Wintels and the LW on the hub and then hook the hub to the router. Is that essentially what you are describing? A reversed pair cable is a two unit closed loop hub, so the same effect as I described before will apply, right? But current setting of letting OSX discover the LW and letting the Wintels use the Mac to print is no real drag, just a few watts of power for an otherwise unused computer.
My HP LJ5MP worked with the PhoneNet/EtherMac connection to its AppleTalk port back when I just used the old 10BaseT hub for my LAN and internet connection (before modern router and switches). However, the new switch technology doesn't recognize the EtherMac output, which is the AppleTalk input. I found that when I put the hub in between the EtherMac and the new switch, the switch recognized the hub, which recognized the EtherMac and everything worked on my LAN. With this setup, both my Mac and my PC notebook on my LAN could see and use the HP LJ5MP.
Alternatively, I later bought a D-Link parallel port print server for the HP LJ. It works quite well on my LAN and is a little bit faster than the AppleTalk/EtherMac/hub setup. I currently have both connections to the HP LJ 5MP hooked to my LAN. I do it for redundancy, as the two different connections function independently of each other, so if there is a problem with one, the other usually works. This is important to me as the HP LJ is my primary printer for all my computers.

Sonnet processors- Encore/MDX Duet processor upgrade card

Just wondering how Sonnet processors (specifically the Sonnet Encore/MDX Duet processor upgrade card for the G4 MDD macs) function with Logic Pro.
If anyone is using these particular cards in conjunciton with Logic Pro 7 on the lastest mac OS X, I'd really like to know how they perform? (these are specifically upgrade cards for the G4 MDD edition macs).
I'm looking to upgrade my 867 MgHz dual-pro. G4 MDD with one of these Sonnet cards.
Any feed back would be appreciated.
Thanks people.

thanks for your input,
I've checked out that site. It's where i originally read about the Sonnet line of upgrade cards .
Great site for tweaking and learning some good **** about your mac systems.
cheers.

Anyone using one of these processor upgrades?

Is anyone using this processor upgrade from Other World Computing?Its this one:
Motorola/Freescale PowerPC G4/7447A Processor running at 1.6GHz
# 512K of 1:1 L2 Cache @ 1.6GHz
# 100MHz or 133MHz bus operation
# Bus Ratio of up to 16:1
I have just recieved a Quicksilver 733(was supposed to be a dual 800,but it was defective),and I would like to max it out without spending nearly $400.00US for one of the 7448's.Is this worth $200.00US?Will I notice performance close to my dual 1.25 MDD?Or is this just a waste of money?Any info at all on this upgrade would be very appreciated,thanks!

Well,duh,I should have just looked at your sig japamac! I forgot you were running one of these,nice to know its reliable.Good to know it will keep up with my current computer as well.Thanks BDAqua as I actually wanted to know if it would at least be better than the dual 800 I didnt get.Dont mind spending the cash,just dont want it to get out of hand if its just a small increase in performance.This will be paired with a 9800pro and sata Hitachi 1TB upgrades,so this shouldnt be a slowpoke with Leopard.And of course I maxed the ram out.Again thanks for the info(and FAST!!)!

Processors upgrades to replace the core i3 330m

what processors upgrades to replace the core i3 330m in the hp pavillion dv6-2150us notebook?
This question was solved.
View Solution.

Hurray It Worked!!!
I upgraded from an Intel i3-330m @ 2.13ghz to an i520m 2.40ghz w/turbo tech running @ 2.93 max.
now my quest is to try the i7-640m 2.80ghz w/turbo tech that max out at 3.46ghz which will maybe be max cpu upgrade for this laptop. as i stated earlier though the cpu-z stats and the hp manual say the -7-720qm and 820qm will work, they didnt so no chance of a quad core solution for this motherboard and finding another motherboard has been trying. My windows 7 score went from 6.3 up to 6.8 with this cpu upgrade so i can imagine the boost of going to the i7 cpu next. Basicly I feel that this board will only use the Intel Arrandale processor only. so heres the link to the Intel website to view processor comparisons to which you will try for your cpu upgrade. : http://ark.intel.com/compare/47341,43544,49666,50179,43560,47663.

Processor Upgrade Questions

I've seen Xserve dual 1GHz (133MHz) bus processor modules on ebay.
Question 1. Will these work in a low end 1GHz single cpu MDD (FW800)?
Question 2. What kind of, if any, speed increase would there be?

Yes, it should work just fine, seeing how you have the same 133 MHz bus. You would see a pretty sizeable speed increase because you would be spreading the load between two processors insteadn of cramming it all on one. I know that my dual 1 GHz PM blows away my iBook which has a 200 MHz advantage in CPU speed but only one CPU.

G4 Processor Upgrades - Anyone experienced them?

Okay so you can get upgrades from OCW, Sonnet and Powerlogix to change your G4 400 sawtooth to a 2.0Ghz beast, but how effective are they? Is it worth forking the £200 ($350)+ amount of cash, or is it more worthwhile to buy a a new G5?

sorry guy this is the forum for Expanding the Power Mac G4 (MDD) and (FW 800)
for MDD there are not any std processor upgrades sold on market (other than ebay or other sites selling modules pulled from other MDD).
if u want real speed buying a PMG5 is better because you will get faster ram, faster bus, faster video, etc...

Ventilation and dual processor upgrades

Hi to all,
I recently decided to change the ventilation on my powermac G4 dual 1ghz MDD. I'm getting tired of its noisiness.
Doing a little research i fell on some dual processor upgrades and thought i could do both.
Has anybody tried Gigadesigns processor upgrades?
<www.gigadesigns.com/index.asp?PageAction=VIEWPROD&ProdID=4>
If so, are you happy with it? is it worth it? Does it help for the noise?
I use my G4 for intensive editing(FCP,studio pro, After effects) and would enjoy a G5. But while i'm waiting for that to be possible, would it be worth patching up the G4?
Thank you very much for your feedback..
tee.

sorry dude. the MDD G4's cannot, technically, use any upgrade processors...
unless you found someone willing to sell you their dual 1.42GHz G4 dual module. or your could whip out your soldering gun do a little OC'ing.
for cooling though--->
there is a nifty cooling solution you can implement if your MDD is out of warranty. Verax, its out of Germany. they have some nice cooling setups for MDD. One is for the giant 120mm system fan, the other listed below is for
the dual CPUs.
here is a link-->
http://www.verax.de/verax.php?template=catalog_entry&entryid=44
I've read about these Verax coolers once before back when I first got my G4 MDD, because many of the MDD mdoels were noisy as heck, and dubbed the
"Windtunnel Mac."
On a side note, i even read about people encasing their G4 MDD inside of noise proof boxes and such.

MDD FW800 video card questions?

Greetings!
i have a mdd dual 1.25 fw800. it has a radeon 9000 pro -64mb memory.
i came across a NVIDIA GeForce 7300 GT - 256mb memory from a Mac Pro 2.66ghz x 4 for $35.
is this a worthwhile video upgrade? a lot of video i watch or download is pixelated and or choppy
will this work and/or what would be required to make it work?
flashing is probably beyond me, but the pin blocking modification i've read about for some cards is not.
i'm using a 24" benq monitor.
many thanks!
chris
i'm posting here also as i haven't gotten any responses elsewhere. ct

Hey Darkey, I'm from Long Island too.
Anyway, I have a G4 MDD Dual and upgraded to an ATI 9600 Mac Pro.
It has been working just fine for me since the original ATI 9000.
There is the ATI 9800 also, but it runs HOT and I have seen many posts where it has caused problems and the fan it has sometimes burns out soon.
The 9600 is only 256 MB VRAM , supports Core Image, and Quartz Extreme and Much of OpenGL 1.4 and is way better than the 9000.
I get few problems with video any more.
Unfortunately it's just over $200.. but well worth it, if you see one of those on ebay.
Just make sure it's the right one, and not a flashed PC version (which are cheaper).
Good Luck.

Processor Upgrade for iMac G3

Hello, I didn't see any particular posts specifically pertaining to the slot loading iMac (Graphite)..I hope someone can help me out.
I have a G3 Graphite iMac, upgraded RAM currently running Tiger. I used to use it but wiped it clean, re-installied the OS and created a separate account for my 8y/o son, so essentially there aren't many apps on there. For some reason it's running slower than it should, even with just Safari open. Is there a fix or possibly a processor upgrade for this model (I keep seeing that there isn't, but I want to be sure).
It's either that or constantly hearing my son complain of the lagtime and ask for our laptops instead...

According to Mactracker at one point there was a 700 MHz model available in Graphite & Snow. If you could find a 700 MHz G3 CRT iMac logic board on eBay it might be possible to upgrade the processor speed. You could also install a Matshita SR-8184 or SR-8186 DVD-ROM drive.
There's firmware available for both drives that allow them to be flashed to RPC1 or region free meaning they can play DVDs from any region in the world. Normally the drive is restricted to being able to only play Region 3 DVDs from the US. If you order a Matshita SR-8184CD optical drive from www.welovemacs.com call their 800 number listed on their website & be sure to ask for Jessica or Faith since some of the optical drives they sell don't have RPC1 firmware available for them.
