What are exact Pegasso2 memory needs? only things what i remember are PC2100,DDR.but any other needs. I have currently only 256megabytes and i think adding more is not silly.

I added in my Peggy 2 Corsair modules PC2400 (or 2700, I don't remember anymore), blue heatspreaders type, 1 Gigabyte each module, for a total of 2GBytes.

2400 more megahertz bandwidth is not supported by Pegasos that is limited by bandwidth of northbridge chip, and memory over 1,5 Gigabytes is not seen by MorphOS memory management, but it works flawlessly...
And 1 GB and a half is more than any morphos or amiga software could dream of, to manage its data.

Yes, PC2100 DDR266 184-pin according to the spec. For more information I recommend to read this thread:

There is still a memory vendor that guarantees compatibility of 1.0 and 0.5 GiB modules with Pegasos II:

Crucial memory when made itself seems be non ecc should be such? or both works.

Actually, this depends. See the above-linked thread for details.

Tell this to OWB which leaks memory like mad :-)

The Pegasos II memory controller supports both ECC and non-ECC.

Good. And some coding ideas what i have i bet going use much memory becouse one kind data uses much memory and is not realted platform but pure fact if picture is 4096x3072 and for example 16bit rgb valus (all componetns are 16bit) then is big. and this kind things.

I think I mentioned I tried a stick of 2gb EEC memory in Peg2, didn't work.


Sold the memory on eBay, with warning that it didn't work on my, rather unusual Pegasos 2, and they buyer said it worked fine.

So I don't think the Pegasos supports EEC memory, I know that it principal it does, but in reality, probably not.

True, you did:

I gave you a link to a MorphZone thread where users reported their Pegasos II working well with ECC memory (1.0 GiB and 0.5 GiB modules):

https://morph.zone/modules/newbb_plus/viewtopic.php?forum=11&topic_id=5724&start=45

So the reason it didn't work with the 2 GiB module might have to do with the size rather than ECC.

Best program to handle and apply effects on very big images in Amiga and MorphOS are ImageFX and ImageFX lite that own their virtual memory image cache system. Other software are prone to fail and crash. Professor Peruggi loaded huuuge 16000x16000 long camp deep space Hubble Telescope images from NASA site as a test for ImageFX on Pegasos MorphOS and it munched pixels with no any flaw.

Yes i know ImageFX. Did you know very likely if i have time i going code own image processing stuff comp+uters what i use. Sthff what we never seen abd sine if then are stuff what
