Hi all,
Does anyone out there have a gvp 4MB 64pin simms for sale. One of the simms in my gvp A530 seems to be bad:furious:. Preferably in the USA but will entertain any offers outside also.
thanks,
Mech

Wouldn't it be easier just to replace the RAM chips?

Easier no, cheaper probably. I was going to see if anyone had one laying around before i did that.:)

It will be easier & faster, these GVP SIMMs are hard to come by as you know. :)

Someone on Amibay made up a batch of 16MB ones last summer, but I missed the post and they didn't last long. Don't understand why someone with hardware experience doesn't ramp up a batch of these more often? Seems like they'd make good money off them... :(

I will be making quite a few. Lets see how pcbs come. They are 4 layers.

W00t! If you're making the 16MB ones, put me down for at least four! :)

Buddy, if I can score some good 16MB ones, you're first in line for my four 4MB ones. ;)

can you recommend me a good program to test fastram on the GVP040?
I will be testing 4mb and 16mb simms.

Hi!
Not surprisingly I already have several memory tester programs on my hard drive. Haven't ran them in a while so gave them a whirl a few minutes ago:
http://aminet.net/package/util/misc/memtest - worked fine
http://aminet.net/package/util/moni/MemTest - locked up on my system
http://aminet.net/package/util/misc/pmemtest - worked fine
http://amiga.resource.cx/exp/gforce2040 - 1.51, worked fine
I ran all four from Shell booting with no Startup-Sequence. Hope that helps, if you come across any more you'd like me to test let me know.
Also, I think the RAM has to be at least 60n's for burst mode to work, but I might be confusing that with the VXL*30 in my A500. Still, the faster the better! ;)
-
will give a try as soon as I have the pcbs with me.

Good luck with your project! You will make bank if you're able to get them working! :)

Hi!
For now I have tested 5 4mb simms. I am waiting for memory chips.
I can sell for 25 euros each plus postage if anyone wants.
Cheers!

4mb simms are good... 16mb would be nicer :)
