Hi,

I have a TF534 rev 2c with a 33mhz 030 / 82 clocked at 36mhz 4MB ram. What is the best ram upgrade to fit with the TF534 on a 1MB chipram rev6 A500? I Have a compatible GVP Impact with 2MB z2 ram but found it not very ergonomic as the box is big when connected to the A500. I have another upgrade, the Supra rx500 2MB z2 but it seem non compatible with the Tf534 as the ks3.1 warn me that the thing is defective when it's not true.

Hmmm unsure. I tested a bunch of cards. Including the Gvp

It is possible to upgrade my tf534 4MB to 8MB?

Read the pinned post at the top of this forum.

Thank you for allowing me to join the forum. I get exact the same issue as Berty Boy does with a Supra Ram 500RX with my TF534. When booting with my original 680000 it shows up fine, but with the TF installed it shows as defective on boot.

Has this been addressed, or will the expansion (Supra) never be compatible with the TF.

Finally its a great card, and would be great to have a bit more ram to play with.

The Supra has 4mb on board

Kind Regards

From my little bit of troubleshooting with Diagrom, it appears the SupraRam doesn’t autoconfig correctly. It seems to always locate the RAM at a fixed location. That is, if autoconfig tells it to locate the RAM at a given address, it uses a different address instead. This causes a conflict with the TF RAM.

Supra Ram isn't working with any other expansion not just TF cards :!:
And remember - any (Trapdoor) expansion will add problems to Your system, or make Your system run slow / unstable, so better leave it just as it is, TF530 and TF534 are great LowEnd cards, these was perfect three years ago, where we had no IDE and no FastRam at all. Evolution of TF cards is amasing if You look on TF330 for example, just be patient and You'll be able to build TF536 with 64 or even 128MB - this will be enough to run any game / demo :arrow:

Thanks for the feedback everyone :-)
