GVP A500 HD8+

Hi,

What RAM should I buy to upgrade my GVP A500 HD8+?

Pop it open and check.. Its usually 30 pin simms, so 4x1mb simms.

Best checking first though some gvp stuff uses custom gvp simms.

I had a hd8 a while back and it took the standard 30 pin simms i pulled from an old pc motherboard no problem.

I remember my HD8+ took standard 30 pin simms. What sizes it supported I can't remember though. I think I just put 4 1MB simms in it.

As much as I know it should reach up to 8MB!

Two 4mbyte * 30-pin SIMMS

Thanks ... can I buy four 2mbyte * 30-pin SIMMS or they do not exist? I am asking because on this image it seems there are four slots.

[Munchkin]

There is 4 slots, at least in mine just as on that picture. Think that 8MB is maximum though.

Mine has 4 slots, I think max 2mb SIMMS to equal 8mb. There is a jumper diagram in there if you pop the top off, i'll take a pic of mine if yours is missing the label.

if you have the time I would really appreciate that I bought my GVP second hand and do not have any manuals.

Use either 1MB SIMMS's for a maximum of 4MB or use 2 4MB SIMM's to get the full 8MB. I have never seen 2MB SIMM's (30 pins), nor do the jumper positions suggest they exist.

Get the jumper settings from the amiga hardware database

Good, that is what I wanted to know .. I know what's next on my shopping list.

Just another question. From one of the above posts someone suggested that the RAM could be of a normal PC!!? is this true?

Regardless as to whether they exist you could almost certainly not use them. 1MB or 4MB SIMMS are the only two types that are described as being compatible.

When using 2*4MB SIMMS you have to put the SIMMS in slots 0 and 2.

2 mb 30 pins simply do not exist probably because there are no double sided 30 pin SIMMs. (wild guess here)

[EdFlux]

It's 2x4mb, sorry, it's been a while since I worked with 30pin SIMMS. Sorry for the incorrect info.

Sorry, that would be slots 0 and 1. CN9 and CN10 to be more precise.
