@Massi,

Your problem may be more CPU/Buss speed than graphics mem.

@Rob

Don't even suggest it, it might be taken literally.

I know of one guy who got a hacksaw and cut the corresponding slot in his new card to make it fit. I don't know what happened when he turned the power on.

I'm merely quoting ACube's own words, from their manual. Some people don't read them.

Funnily enough I actually saw a mod last week for turning x8 PCIe card into a x1 card by doing just that.

@tonyw

Unless his hacksawing skills were exceedingly bad I expect it simply worked.

A much easier solution (if there is space on the motherboard) is to just cut away some plastic from the socket, to make it open ended. There's still guiding in the other end and the keying tab.

@Rob

(some finn fitting a PCIex16 card into x1 slot, do not try this with your Amiga (debug on x86 first))

(olegil's way is better, as long as there is no components on the way of the x16 card to fit)

When designing new boards:
I think it would be good idea to use open ended x1 and x4 connectors rather than closed ones.
Or alternatively, just use x16 physical connectors also for x1...x8 slots.

(free hint to a-eon ... )

I know this was a problem with Eyetech A1's but didn't think it was an issue with Sam's.

It was a driver problem I think. The driver couldn't handle multiple banks of gfx memory, OR it was very difficult to find the second bank or something.... In the beginning the driver would assume all memory was in one chunk but when 128MB was used up the driver started "using" memory where there was no memory on the card, because the second bank was elsewhere. Something like that. Doubt it was an AmigaOne issue.

I think tonyw was talking about a normal PCI card, to make it fit in a wrong voltage slot. I also heard that story...

@All

Thanks for all contributions ... can someone recommend a specific model that is known to work well?

Changed the Radeon 8500 that was installed to the XE to a ASUS 9250 AGPx8 (128MB DDR) as Hyperion said it was the most supported one.

Good or bad move?

More later heard it's slower? The guys were releaved in the local shop that they got rid of such old HW and this was a few years ago;) Not too expensive either.

Well, it works fine and is cooler. 9200 Pro should be faster so got a bit confused about this numbering idea? I think we know better than many else.

Maybe a graphics test?

Found the 9250 box and it says AGP or PCI express, has DVI but using VGA as the displays input in the monitor is reserved for the pc's vga that has two so it's quite handy with a kb+mouseswitch.

@PR

8500 is not fully supported by OS4, so good choice.

@pavlor

Thanks. Tested Mui4, Dopus and OWB all worked fine. Youtube was a bit slow but it worked. This is about optimazing maybe or could we get more from the GFX card as it's been the best supported;)

@All

Does anyone own a Radeon 9250 (PCI, 256 MB, 128 BIT, DDR, VGA, DVI, TV-OUT) for the SAM440EP-FLEX?

Does it have a passive cooling?

From which manufacturer (ATI, Sapphire, ...)?

I hope to get a precise response, thanks.

You can compare different video cards (yes, even our "current" old ones) at gpureview.com. Select "Compare cards", and you can compare 2 different models side by side.

However, note that:
-All our currently "3D supported" cards are rather ancient compared to anything more modern, and speed differences betwen them, while perhaps noticeable, might not alone be good enough reason to upgrade.
-Even if it looks like same card, units produced by different manufacturers can vary greatly.
-Instead of pure speed, also consider other factors, such as noise (active / passive cooling), available connectors and software support (3D acceleration, overlay...)

On MorphOS, people recommend always trying to get the 128bit version (instead of 64bit). I guess OS4 will also benefit from this the most, as it affects the overall bus speed (and slow bus is even worse when you lack VBO support, like we do... Of course games also need to support it)

And yes, if there are some driver issues with 8500, 9000, 9100 and 9200 on OS4, I'd recommend avoiding them too. But on the other hand, wouldn't recommend "downgrade" from such board you already own, unless you really DO have some issues (crashes, gfx corruption, whatever) or missing features (no overlay or such)

@Jupp3

PIV is very nice too;)

I think all these "pc crap" are fine compared to the zero work they have to do.
Bought a NVidia 8800 GTX Extraturbo Special Porsche injection and it gave a few years more for a stock pc.

I'd like that and drivers to make a HTML5 video in Youtybe to work flawlessly. Should not be about the HW. Interestingly waiting for a fast booting Net machine. Since 2002;) (My XE..)

Typing with an A1200...

To get a 5v card to fit in a 3.3v sot wouldn't you have to remove the card's rear bracket and install it the wrong way round?

yes I think you are correct with this.

@Deniil715,

The post I was responding to in that thread was about his original performance issue. Samflex with a 733 processor and its bus are not the fastest.

PS: I still haven't heard of any other A1 machines having the "no 256 mem" showing problem except for the Eyetech ones.

EEEEEK. No, that's not it at all. The connector is backwards, but the pins are the right way. If you plug it in backwards you'll do ALL sorts of wrong.

I cannot for the life of me figure out why people wouldn't be making universal voltage PCI cards in this day and age.

I don't think Rob and realize really meant that you should insert cards backwards, I think they more meant to illustrate (in extreme) how it's not possible to physically fit a 5V card in a 3.3V slot by mistake (or vice versa), as a response to tonyw's claim that you could damage the SAM by inserting incompatible cards!

If anyone is doubtful about this and how it works, look at the left column (32-bit) in this picture to see the difference (both slots and cards):





Pay attention to the different placement of the "key notches" on the two variants, and also how universal cards has two key notches so it can fit in any socket.

AFAIK most graphic cards were indeed universal (thus having two key notches). Like this:

Some 256Mb cards have one bank of 256 and some have two banks of 128.

Yes that sounds like the one I was thinking of.

http://www.diamondmm.com/s9250pci256-diamond-amd-radeon-9250pci-256mb-ddr-video-graphics-card.html

What do you think guys about this one here?

1)
The PCI slot seems compatible.

2)
The memory specs say MEM Config : 16Mx16
Does it mean a 256 MB chunk?

3)
It does have active cooling, I would prefer passive, anyway.
