I've had a Mac Pro 1.1 for years, its still going strong and there are no problems - I want to max the out thew RAM to 32GB

At the moment it has 10GB. The last time I bought RAM for it was about 9 years through Crucial, I checked them again and they don't seem to stock RAM for the this model of Mac Pro anymore - they do provide SSDs
(but that's a question for another tread).

I came across two other vendors

https://www.mrmemory.co.uk/memory-r...n#!ddr2-pc2-6400-800mhz-240-pin-apple-mac-pro

The above company provide RAM in two configurations (both come in pairs)
2GB - 667MHz - £29.99
4GB - 800MHz - £28.50

The RAM currently inside the Mac Pro 677MHz, as far as I've read the 800MHz is compatible? If I was going to buy from it would have to be the 4GB pairs to max the RAM.

The other supplier, supplies OWC RAM

A 4GB pair here is £74.79 - per pair. Maxing RAM this way would be a lot more expensive, but I imagine its the way to go?

Which one should I go for?
 
800MHz should be compatible, if the rest of the specs matches. They would just be running at standard 667MHz. Just don't go slower.

Regarding maxing out: I seem to remember that there has been a long thread (or perhaps multiple ones) that discussed the Pro's & Con's of doing that. Quintessence was (iirc) that you would have to suffer from a speed loss (either from maxing out itself or from not considering the dual channel configs - can't remember anymore), but that that could be negligible if your workflow benefits from having more Ram.

Search the forum and take a read.

Slow down is caused by maxed out RAM config and a PCIe SSD. With 8X4GB you are nowhere near the optimum 56GB or the maximum 64GB.
