RAM upgrade for my SE30?

[ChrisW381]

Have a restored and recapped SE30 with 40mins HDD and 8 Meg RAM using all the slots. So I would like to take it up to 128 meg if possible. Best place to get these chips please?

128MB is a huge amount of RAM. For normal use, 20 is plenty, 32 is crazy and 64 is more than you could ever imagine using.

This said, OWC sells 16MB SIMMs with a lifetime warranty I believe.

16MB OWC Memory Upgrade Module

Upgrade your Mac memory and save money by trading in the original factory memory chips. Includes a lifetime OWC warranty.

As long as they're not too tall for the SE/30 - watch putting them in. The clearance isn't great and if it snags you can damage things (with any SIMMs, not just these).

If you don't have something particular in mind, I'd suggest just getting four to start.

Also bear in mind that a 128MB memory test in an SE/30 will take about 4-5 minutes… so it makes the boot time very slow indeed. I’d say go for 32MB or 64MB instead.

But yeah those OWC sticks or MemoryMasters work.

Many thanks all, gone for 32 meg (2x sticks) so just waiting for the shipping from the US

Sadly this won't work - the RAM is arranged in banks of four SIMMs (each SIMM is 8bits wide, and connected to a 32bit bus).

You have to fill each bank of four slots with four identical SIMMs.

For 32MB you would need four 4MB SIMMs, in both banks for eight 4MB SIMMs total, if you're using 16MB SIMMs, yould be putting 64MB in one bank.

You'd also still likely have four 1MB SIMMs in the other bank. Just because, well, you're not going to leave it empty. Why would you

Ok thanks well that’s a bummer, Will have to see what turns up in terms of size of the chips then order again

If they haven't dispatched your order, drop them a message and ask can you update your order.

See if you can avoid paying for shipping twice.
