    What is the best currently available CPU upgrade for a digital audio G4 tower?

    Same question regarding video card.

    May be looking to upgrade my G4 and would like to know the best options.

    Thanks!

    Other World Computing sell a 1.6GHz dual G4 upgrade, and you should be able to get the GeForce 7800 GS working.

    I saw those cpu upgrades at OWC. Is the dual 1.6 really worth twice the price of a single 1.6? Will the difference be that noticeable?

    Thanks!

    I'd certainly say it should be so, give my previous experience with single vs dual processor systems... it's expensive though, I was in the same position of you, and realised that it was actually cheaper to buy a dual 1.8GHz Power mac G5 than even the single processor 1.6GHz G4 upgrade... if you have the money though, it's worth it.

    Not trying to offend you but how can a person who doesn't even understand how memory works and asks questions like will an iMac HD work in other Macs really give any valid advice? Your understanding of your own computer is remedial at best so how can you possibly think you can help someone else? People like you sway others in the wrong direction because you don't know anything past the basics and even some of the basics are not understood by you.

    AtmChm:

    If you can find a single or dual 7448 G4 upgrade on ebay I would buy that. Even a single 7448 will be faster than any dual G4. If you can't find a 7448 CPU daughtercard then try to find a dual 7455 upgrade used. If the first 2 can't be found then settle on the dual 1.6GHz 7447 from OWC. The 7448 and 7455 are faster than a 7447 in any situation. You will certainly notice improved performance over the single. Don't buy a G5 like the uninformed one above suggests. They are by far the most unreliable Macs ever made.

    IMO the best video card for a Digital Audio would be a 256MB Radeon 9800 Pro. A 7800 is much better suited in an MDD. The DA PSU is only about 330 watts and the 7800 could easily be too much for it.

    Funny enough, I actually expected a reply like that, be *nice*, even if sometimes I am an (intoxicated) idiot, my reply THIS TIME was accurate, if you think he can upgrade PAST what I said than please correct me.

    Also, I can tell that you do not have first hand (positive) G5 experience, being a former Apple tech I know that they can in fact be very unreliable , but if you find a *good* one, then a G4 is no match. If money is no issue I would not ever hesitate to advise a G4, I am one of the lucky few to take a gamble on a G5 that has so far been great for me.

    Despite that, I will admit that you know more about G4s than me so I will yield the remainder of this thread to you and we will have to agree to sometimes disagree.

    I have been using and working on G5's since 2003 when they came out. I have plenty of direct experience with them and thats why I have never bought one myself. I have setup entire clusters of 20+ G5's and maintained them all for 3 years.

    Sorry but I cannot believe that someone who asks the type of questions you make threads for could possibly be a tech of any computer type.

    Now back to the question at hand..

    The best G4 upgrade is the 7448. Period.

    here your next CPU
    [​IMG]
    This upgrade will make your Digital audio fly and will make it easy keep up with G5 PowerMac's (runs circles around the single processor G5's) and still keeps up with early intel core duo Mac's :)

    sounds expensive , but is worth every cent

    and for the GPU , you could try to find a a ATI Radeon 9600 128MB VRAM(as second choice )because the ATI Radeon 9800 256MB is harder to find, AGP cards and obviously Mac editions

    dont forget to max out the RAM and make sure you got the latest firmware upgrade (4.2.8 is the last to my knowledge)

    I agree that the 7448 is the best G4 upgrade ever, but G5's are not that bad, but compare it with the G4's, G4's are more "solid".

    Do they make a G4 Powerbook upgrade for those who don't like the 7447a or 7447b 1.67 chip? I heard of Daystar making logic board upgrades for Powerbook G4's to allow 1.8 or 1.9 7448 if I am correct?

    Even my G4 MDD is faster than my 2006 Powerbook G4 1.67

    I just wish one could get the 7448 upgrade for the G4 Powerbook. It seems my G4 MDD is much faster than my 2006 G4 Powerbook because of the fact it uses a 7447a/b processor. I remember that Daystar produced upgrades for the Powerbook G4's. Mine is a DLSD 17 inch PB G4 1.67. I like it to death, but wish it were a lot faster. Is 7448 socket compatible? I know I would have to unsolder the 7447a/b processor and put the 7448 in its place. Has someone done this?

    not for your PowerBook to my knowledge ,the daystar upgrade was as far as i know for the titanium PowerBooks

    dont even know if they still built them , but i have seen one nearly 2 years ago on craiglist London it was a Powerbook G4 867 with daystar upgrade to 1.33 ghz ..in immaculate condition no scratches whatsoever according owner and pictures ...i was to late as it sold already 15 minutes after it was listed for £500 , the owner said i was already the 20th or so who did call and it was only 30 minutes after he did list it :(

    Yeah I know, but is it possible for the 7448 to fit in place of the 7447a/b chip? I know a friend who is good with micro soldering, but has anyone tried to replace the 7447 with a 7448 in an aluminum powerbook G4 dual layer or any powerbook for that matter?

    Is it even worth it even if I could get the 7448 chip?

    i never done it , so i cant answer you the question as i know nobody who has tried to upgrade a PowerBook with a 4778 cpu , would be great if possible , but maybe you got more luck with a answer if you make a separate thread like "PowerBook G4 cpu upgrade to 4778 ? "

    but remember to ask your mate if he really can desolder and resolder a lot of microscopic tiny pins and i mean a lot , its like soldering in the socket of a PC a couple hundred tiny pins or so and none of them have to get in contact with each other


    i guess if you overclock your Powerbook it's a bit is easier ..if you want to risk that for max 200mhz and that is max if you dont want to transform it into a fryer . that is because unlike in a desktop there is not much room for more heat and higher clockspeed means more heat using the same processor not to mention the extra power needed so your battery will drain faster too .
    Those fast daystar upgrades need ac power in order to run at full 1.83 ghz + and they are practically just overclocked processors but done by professionals

    Technically possible:

    But adjustment of Core Voltage and PLL settings coud be needed, what has to be done on Powerbook's logic board.

    I'm very curious about real life result of such an upgrade. 7448 runs much cooler than 7447 so it would be perfect for Powerbook, heat emission-wise.

    If you'd have technical possibilities and 167 MHz bus PB and 7448 chip to sacrifice, I'd love to see them running together :)

    I have the same upgrade MacHamster68 shows the picture and info of above. Saddly the 7448 upgrades are no longer made for lack of demand. OWC told me on the phone in 09 when I bought my 7448 that they sold 3-4 7447 for every 1 7448. This was due to a 7448 of the same speed being 150-250 more. The added performance was/is well worth the added cost though. My single 1.8GHz 7448 cost 375 in June 2009.

    They are hard but not impossible to find on ebay now.

    Yes, that cpu upgrade would be very good if it were still available. But when you click to buy it, you get re-directed to the OWC website where it says it's sold out.

    I may look around e-bay for a while, but otherwise the 7447 from OWC seems like the best thing still in production/available. I guess I am still wondering if the dual 1.6 GHz would be that much better than the singe one to justify twice the price.

    Thanks for all the suggestions on video cards!

    No you can't. OWC is NewerTech. Same company. The 7448 are no longer made. Period.

    What's actually the most power efficient G4-CPU-Upgrade, i.e. most processing power per Watt.

    (One would have to consider, too, that for a given task, maybe a more energy hungry CPU is less costy, because it gets the job done quicker...)

    The 7448 is by far the most efficient. Least power consumption and the most performance per mhz. It's at least 40% faster than the 7447 before it and uses less than half the power. In turn it is also the coolest running.

    Just wondering, If this chip is this good, how come apple never decided to ship it? Was it due to the Intel switch?
