1.25 167 MHZ processor upgrade for a dual 867 133 MHz bus

Having upgraded my MDD with a dual 1.25 processor, I am left with a single 1.25 processor at 167 MHZ bus. Can I use this to upgrade a dual 867 MHZ MDD? I know I won't get the original speed due to lower bus freq, but I'd like to use it anyway, especially if the heatsink fits.

Hi there, that's going to leave you with a single 1 GHz CPU vs. 2 867s, unless you also bump the speed multiplier, but...

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.

SCSI card for a G5 or processor upgrade for a G4?

Hi all
Actually, this is a question that concerns the G5 and the G4 forum, but I decided to post it here first.
So, I have this old G4/400 PCI with an Adaptec 2930 SCSI card that I use for scanning slides with an Artix 4000t sclide scanner; this works fine, but the G4 is rather slow when it comes to using some features of the scanning software, such as removing scratches.
I've been thinking about buying a SCSI card for my G5 (Dual 1.8) for some time now, but I'm not sure what card I should go for; I'm not even sure if there are still cards for such an "old" device as the slide scanner (about 3 to 4 years old, no Ultrawide or something like that). And then there's the problem of the drivers for the card - how long will they be available, especially now that Apple is switching to Intel...?
The other possibility would be to buy a processor upgrade for the G4. I've seen some at OWC, and they seem to be less expensive than a SCSI card. The drawback of this solution is of course that I'll have to keep the G4 standing on my desk... on the other hand, I do know that the scanner will work perfectly with the G4.
The G5, on the other hand... it will be faster and easier, since I won't have to transfer the files for storage and editing, I could free some space on my desk,... but will it work? The G5 is running 10.4, I'm not sure if my current scanner driver is compatible... and what when 10.5 comes out...?
So I'm looking for a second, third, fourth... opinion:
What would you do? Get a SCSI card for the G5 or a processor upgrade for the G4? What SCSI card would you recommend?
TIA,
Tina

I've done some research on G5 and SCSI and scanners, and obviously, what I remembered was correct... making it work seems at least tricky, and maybe expensive too (if you've got to buy new scanning software and and..).
So I guess that's decided: No SCSI on the G5. Leaves the question, should I buy a processor upgrade card for the G4? Getting some dual G4 on eBay might be an option, but then, that would be another computer in my already crammed office, and I just can't throw the G4 away, it's one of the very first models...
I came by the idea of a processor upgrade because I just played around with an old Mac SE, which has an 68030 accelerator card installed, and this seems to work fine. Anyone has any experience with G3 /G4 upgrades (good or bad)?
Smokerz: Why would you not recommend an upgrade? Any bad experiences?

Processors upgrade for ECS 945GCT-HM Livermore-GL6

Hi all,
I really want to know which processors that I can upgrade for this motherboard.
On HP specs it can only upgrade to intel e4300.
Which I don't totally understand why I can't upgrade to e4400 or e4500 or e4600 or e4700 as they have the same FSB of 800MHz...
Can someboday explain me why I can't..
I wouldn't even posting this message if I could find e4300 but that seems totally impossible as it is really old processor.
I really can't afford to buy a new desktop at the moment.
I am deeply appericated if somebody could help me out with this...
Thank you

So the following upgrades will help:
Upgrade the processor to the top model listed
Upgrade the memory to 2GB
Install a discrete video card. Without changing out the power supply, the NVIDIA GT 240 1gb DDR5 is an excellent card.
If it's gaming or video performance that you need then do the video card first.

Where do I find upgrades for my imac G4, 800 mhz for OSX?

I have an IMAC G4 that is currently running OS X 10.2.8
I need to upgrade my safari since it mis-reads some pages when using this IMAC. But I can't upgrade safari unless I can upgrade the OS X.
I can find upgrades for 10.3.9 but can't install without upgrading to 10.3.
No where on the apple website is there an upgrade to bring my 10.2.8 into the 10.3. Was this a major upgrade that required a purchase?
My other mac is an ibook, running 10.3.9. Ideas on how I can find this other upgrade for my imac?

Hello Kathy:
OS X 10.2.8 is the last one in that release.
"No where on the apple website is there an upgrade to bring my 10.2.8 into the 10.3. Was this a major upgrade that required a purchase?"
The answer to this question is yes OS X 10.3 is a new release of OS X.
If you are considering upgrading, I would consider OS X 10.4 The new Safari (2.0.1) is faster and has an RSS reader. You can go directly from where you are (10.2.8) to Tiger (OS X 10.4). I would suggest an archive and install if you decide to proceed:
http://docs.info.apple.com/article.html?artnum=107120.
Your iBook no doubt came with 10.3 installed. In addition to being illegal (according to the license agreement) your iBook install software would probably not work on your iMac. If you wish to get OS X 10.4, purchase a 'family' license. In that way, you may legally install on up to five computers in your household.

Processor upgrades for PowerMacG4

I have recently get a PowerMac G4 dual processor tower because it was the only way to operate my adc apple cinema HD display correctly. The machine is about 6 years old now and works perfectly. In order to achieve good performance in the future (i'm thinkin to switch to Leopard) I'm considering upgrading my processors, video card and slave disk space.
Does someone can tell me truth about does dual processors upgrades offered by Newertech (2x7448 PPc particulary), Gigadesgin and Sonnet? Does it worth the price (up to 700$ in some case if you want top clocked models) configuring that I want enough power to expect to: -record multitrack audio with Logic or Pro TOOL; - to use efficiently guitar rig 3 - play some new games and finally keep in my studio this quite cool looking silver tower in the standards some years more. Does it exists any risk to install those upgrades?

Hi!

Memory/Processor upgrade for my K9A2 Platinum V1 board

Hello everyone. I am considering jumping up to a Phenom II x4 940 and 8GB 4 x 2GB sticks of the following memory....
1. Geil Black Dragon GB28GB6400C5QC

2. Geil Black Dragon GB28GB6400C4QC

4. G.Skill F2-8800CL5Q-8GBPI
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231195
5. Or just getting a second set of Corsair XMS2 (TWIN2X4096-6400C5) for a total of 8GB.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820145184
I would just get a 2nd set of corsair memory.... but if I get a quad kit I know I am getting 4 matching modules ( Or at least should ). Instead of memory manufactured a year ago or longer (for original set) and up to this year (for 2nd set). I don't want problems between same type of memory using different chip sets. Oh btw, I would really prefer PC2 8500 or so.
Anyone out there had or have any of these combinations. Or is there other memory that you would recommend instead. Overclockability is a plus.
Oh ya I have also thought about upgrading motherboard as well and get something with the 790X or 790FX/SB750 chip sets instead of the 790FX/SB600. But not quite sure what to get on that end either.
My system specs are below.

Anyone of the above should work fine. I would consider Mushkin XP2-8500 modules, but with 4 x 2 GB modules you will probably have bad overclockability with any memory.
If you have a K9A2 Platinum now, it's not really useful upgrading to a 790FX + SB750 board. Granted, SATA and USB performance should be a bit better with the SB750 and it has RAID 5 support. For the rest, you will not notice the difference...

PLEASE READ!!! Pro Tools user - need tips on processor upgrades for movies

Hello all,
I know this is a FCP forum but thought that you may be able to help.
I'm a Pro Tools user and I bassically wanted to know if there is any hardware (like some sort of card) that I can buy to manage my processor's workload. I would buy a Pro Tools TDM system, but they cost so much.
I just want my Pro Tools to run smoothly (working with video) and right now, with my single processor - i can't. ANY SUGGESTIONS?
- Josh

Truth is, you really need multiple CPU's nowadays, especially for your ProTools filters to stay realtime. And your G4 is getting a little long in the tooth. It's going to be hard to keep it being a viable, up to date machine, as you stuff more and more tasks onto it and expect it to keep up in realtime. There are CPU accelerators for your CPU available (check www.macsales.com, xlr8yourmac.com or others), but you cannot make the jump from one to two procs on your system, and it's a game of declining returns...
If money's an issue, why not sell your G4 and buy a used Dual Proc G5? You may find yourself short only about $1k in the transaction, possibly even less if you get lucky. You will definitely see a major performance difference, and you won't have to reinvest in plugins, cards, etc for the new Intel architecture.

After processor upgrade to sonnett dual 1.8 ghz system crashes

Hi all,
My system keeps crashin when using the dock or switchin software programs usual suspects are photoshop to illustrator to itunes. The screen freezes and i get no mouse movement or keyboard functionality and i have to force the restart.. only seems to be happening since the upgrade of my processor.. also upgraded RAM and added a expansion card for my 400 gb hard drive..any ideas?
happens at least twice daily...

Hello! You have committed a sin by doing multiple upgrades at once. If you upgrade ram, processor and drives at the same time without running each upgrade to make sure it's stable then it's difficult to troubleshoot but ram is agreeable the most likely culprit. Tom

Can FW800 133 MHz board from single 1 GHz machine take a dual processor?

I've read in more than one place that the logic board from the 1 GHz FW800 machine can't be used with ANY dual processor. Can anybody tell me with a reasonable degree of certainty whether this is true or not?
Please don't bother answering based on general principles. I already believe -- tell me if I'm wrong -- that every other MDD FW400 or FW800 board CAN take a dual processor and, except for this question, EVERY processor will work EITHER with EVERY 133 MHz board OR with EVERY 167 MHz board.

From my experience the processor card should be compatible, but don't hang me if I'm wrong.
This page showes how to set different multipliers = bus ratios.
So, according to the default multipliers for the MDDs, you get:
6.5x 133 MHz bus = 864.5 MHz CPU (867 MHz)
6.0x 166 MHz bus = 996 MHz CPU (1.0 GHz)
7.5x 166 MHz bus = 1,245 MHz CPU (1.25 GHz)
Thus, if you put a Dual 1.0 GHz onto a 133 MHz board, you'd get not 1.0 GHz but 800 MHz instead (798 MHz to be exact). The same goes for the 1.25 GHz where you'd get 1.0 GHz (997.5 MHz), and for the 1.42 GHz where it'd be 1,1 GHz (1130 MHz, multiplier 8.5x).
6.0x 133 MHz bus = 798.0 MHz CPU (1.0 GHz → 800 MHz)
7.5x 133 MHz bus = 997.5 MHz CPU (1.25 GHz → 1.0 GHz)
8.5x 133 MHz bus = 1,130 MHz CPU (1.42 GHz → 1.1 GHz)
So, if you alter the bus speed of the board (see here, link is from the xlr8yourmac page linked above) you will be able to use the Dual processors for the 166 MHz bus on your 133 MHz board, then overclocked to 166 MHz, at their designed speeds. If you don't what to change the boards system bus speed the processors will just be underclocked, thus run slower – with all the advantages like less power consumption and less heat emission together with a prolonged lifetime.
To fit the 133 MHz system bus you would have to change the multipliers on the processor daughter card to run at the processors native speeds.
Just one example:
1,000 MHz / 133 MHz = 7.5x
So, if you'd want to run a Dual 1.0 GHz processor on a 133 MHz system board you'd have to alter the multiplier from 6.0x (for the original 166 MHz system bus) to 7.5x (for your 133 MHz system bus) – the resistors to change the multiplier reside on the processor daughter board.
That said, keep in mind that this procedure is *NOT tested or confimed*, but it seems logical, doesn't it?
I had a OWC Mercury Extreme 1.4 GHz processor upgrade placed in a Gigabit Ethernet replaced into a Quicksilver (2001 version). As you can see here, it had set the multiplier to 14x to have it run at 1.4 GHz on the Gigabith Ethernet (100 MHz system bus) and I had to set the jumpers to a multiplier of 10.5x for the Quicksilver (133 MHz system bus).
Thus, if I had put the OWC Mercury Extreme running at 1.4 GHz in the 133 MHz bus Quicksilver unmodified back into the 100 MHz bus Gigabit Ethernet, it would run at 1050 MHz (roughly 1.0 GHz).
That's it. There wouldn't be more to it than that, but the latter source (for changing the motherboards system bus speed) states that Apple put in some protection on the processor daughter card to prevent increase in system bus speed if no dual processor is present. Since this doesn't apply to you as you stick to your 133 MHz system bus it shouldn't bother you.
*But don't blame me* if it should turn out to be completely wrong!
Cheers,
Andreas.

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.

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.

Upgrading for pics and music

I have a 400 MHz Power PC G4, 768 MB SDRAM, L2 cache 1MB, AGP Graphics. OS OS x 10.4.1. This was a gift my wife bought me to replace my pc. It really needs some upgrading to enable me to work with my photos and music library. I had hoped to purchase the newest version of I photo, but find I don't meet the system requirements. Any suggestions or ideas would greatly be appreciated. I can not toss this computer because I love my wife and she really thought she was doing something nice for me. So far it hasn't been, but I am going to find a way to use it. Thanks for looking in and maybe having some ideas.

Although some may argue that it's not cost-effective for a first generation G4 at this point, you could upgrade the processor with a faster one. The performance boost would make continued use of the computer more satisfying, until you can replace it with a newer/faster computer. Other World Computing has some compatible processor upgrades for your G4. For the same $$ spent, you could find a secondhand G4 with a faster processor and system bus speed, as well as a better graphics card and optical drive.

FastMac processor upgrade

I have ordered a Fastmac 1.5 GHz processor upgrade for my PowerMac G4/400 AGP Graphics.
The onboard USB ports are 1.1.
Will this G4 model accept an 2.0 USB card?

Thank you for your answer.
I found two Belkin USB 2.0 cards.
One is Belkin F5U219-LP Hi-Speed USB 2.0 (480Mbps) 3-Port Low Profile 32-bit PCI Card - WIN/MAC
The other is Belkin USB 2.0 Hi-Speed 3-Port PCI Card.
The first one requires a low-profile PCI slot. What is this? Does my G4 has low-profile PCI slots?
I want to order one of them, but I'm afraid to order the wrong one.
Can you help me?

Upgrading my G4 MDD dual 867 with Gigadesigns dual 1.33 upgrade; worth it?

I am updgrading my PowerMac G4 dual 867 and doing most of the usual; ATI Radeon 9800 Pro 256MB AGP video card, more internal hard drives, still debating on SCSI hard drive; then maxing out memory at 2GB (missing anything else to upgrade?)
I am also considering on upgrading the processor to Gigadesigns dual 1.33 processor upgrade (btw, is this the only processor upgrade available for me?). First, is it worth it? Second, will this force me to change out my PC 2100 DDR SDRAM memory modules? Any other foreseen problems with upgrading to the dual 1.33 processor?
I am hoping to get a response from someone who has actually upgraded their MDD dual 867 with Gigadesigns processor and see what they have to say about it.

MDD upgrades were complex, challenging, and there are 6 different configurations and versions of MDDs out there. And the supply of 7455Bs may be a limiting factor.
If you need OS 9 or don't want a G5 (2.0's for $1699 making it affordable "upgrade") and $499 seems acceptable, and your applications will benefit, AND you don't need more than 2GB RAM (which is limiting also)...
The 9800 Radeon adds more heat and noise and $249 to costs, and the fan is loud but also can fail (poor designed product?).
yes for SATA 10K Raptor over SCSI! Less heat, fast, SATA cables are easy to use and don't cost $100 for good stuff.
But you want to spend how much? $1000 - 1200? a pair of Raptors or something? Seriously, get a G5 from Apple Specials. Your MDD can offset the cost later too.
