    Specs:
    Macbook Pro 13", 4gb RAM, 1tb HD, OS X 10.6.8,
    2GB SDRAM in my G3 ?
    My G3 is slow and choppy on some videos
    even though I have a fast server.
    Can I use 2 - 1GB SDRAM for a total of 2GB
    or should I just replace the 256 MB with
    another 512MB SDRAM for total of 1GB ?

    CPU Type: PowerPC 750 (22.15)
    Number Of CPUs: 1
    CPU Speed: 600 MHz
    L2 Cache (per CPU): 256 KB
    Memory: 768 MB
    Bus Speed: 100 MHz
    Boot ROM Version: 4.1.9f1
    Serial Number: RN______LFC

    Memory: 768 MB :
    DIMM0/J13:
    Size: 256 MB
    Type: SDRAM

    Specs:
    27" 5K iMac, 3.3GHz, 256GB Flash Storge, 16GB memory and OS X.11.3.
    Increasing the memory to 1GB may help a little, however the main problem is the speed of the processor. G3's are now old alas and not much will improve them. The main problems are the processor speed, or lack of it, system bus speed and L2 cache speed.

    I do not think the G3 would recognise the 1GB modules.

    Specs:
    MacMini 2.4, 8 Gb, OS 10.10 and 10.6; MacBook 2.4, 4 Gb, OS 10.6.8
    Ditto to Harry's answer, 1 Gb is your maximum, best with 2 x 512 modules. You can use PC-133 (more common) but it will operate at the slower speed of 100 MHz.

    As you'll note, I too operate a 600 MHz G3 iMac, a good machine, but video is its nemesis. Quicktime and the odd .wmv works okay, but not flv or .avi. The ATI Rage 128 Pro or Rage 128 Ultra video card just doesn't foot it either.

    It's on the way, but to save on shipping I emptied the bottles first.
    That hughvane is a nice looking chap.
    Hey Harry, I do make and fly boomerangs here in Oklahoma, USA. but I guess that's off subject.

    Completely off-topic - we throw Australians here in NZ, but they keep coming back!

    My avatar earned me a case of wine, I'll have you know . A Mac mate reckoned I wouldn't leave it there for 12 months, one bottle per month. I became quite attached to it, so there it stays. My mate now reckons it looks better than the real thing. Good to have mates like that.

    More importantly - is your new Mac on its way yet? Do Harry & I need to exercise even greater powers of persuasion?

    Actually hughvane's avatar is very lifelike! And the beer was probably not Miller's Genuine Draught, which is a great drop.
