PowerMac 7600 3.3v ram

[obsolete]

The limited experimentation I've done with bus overclocking suggests that EDO modules can work at faster bus speeds (up to 60MHz) where my FPM modules do not.

Well I'll be damned, ain't that something. Learned something just now, thanks!

So 7600s accept both EDO and FPM (though not mixed) - what are the pros and cons for each choice?

EDO is faster than FPM, but I'm not sure if the 7600 took advantage of that at all or if they just run effectively in FPM mode. I think the 6500/TAM was the only board to actually use EDO as they strongly recommend those over FPM, but I could be mistaken on that.

Were you successful tracking any done? What sizes are you looking for?

I have at least one spare 64 GB Kingston stick, and I have 8 OWC 128s in a system, which is way more than I need.

found a assortment of various sticks from a powermac 7300 listing on ebay, upgraded it from 48mb to 208mb, and upgraded the VRAM from 2MB to 4MB, would like to have more ram tho (1GB would be amazing but theres no way id be able to afford that much for it lol, plus i wouldnt have any use for having that mach ram in it but its neat to hit the ram cealing for the 7300/7600 lol)

208MB is loads there isn't much that needs more and 128MB sticks cost more than they're worth.

Make sure you install them in pairs in the slots as per the manual.

yeah, done all that, 7600 runs great. so happened to come with a OS9 compadible USB card with the original install, will have to find out where the drivers for it live and copy them (i plan to install the newest version of MacOS that has support for the video capture hardware, as the current OS9.1 install doesnt seem to see the hardware, might see if i can find a 7.5.3 restore disk and upgrade from there)

USB drivers can be slightly tricky, you have to install them with the card in there usually, and I find you have to do a manual install and pick an option that /means/ "PCI or PCMCIA card" but doesn't say it - it says something.... I'll check and update this comment. BRB

Edit : "USB Adapter Support"

(Thank you @croissantking )

I'm not sure why you'd start from 7.5.3 and upgrade to 9.1 though - it won't change AV compatibility. I suspect it just works in OS9. I remember using iTunes on the Video out on my 8600, and suspect that was OS 9.1 from a clean install.

ill have to take a look further in OS9, though iirc the video player program (forgot what its called) that has the AV capture program wasnt in the OS anywhere so the previous owner mightve un-selected it when they clean installed OS9 or something. (though im curious that its like using OS 7.5, have never used it before)

Yeah, it's easy to pick and choose what software goes in. You can just re-install the missing bits over the top using an install disk for the same version, or you could grab a copy of Adobe Premiere 4 or something and play with that.

7.5 is nice enough, on a 7600 I'd sooner install 7.6.1 because it feels more stable (probably personal preference), but with 200MB RAM, I'd probably just run 8.6.

Keep in mind that USB doesn't work in 7.5.

The best solution though is always to install several different OSes on different disks or on different partitions

I generally tend to partition my disks into multiple parts and put a few different OS versions so I can switch between them depending on what I want. My 8600 has like, 7.6.1, 8.6 and 9.1 on it, or something like that.
