GOLD 2.9.x Crashing My Amiga

Hi everyone!

I have successfully upgraded my Vampire V2 with the new GOLD 2.9.x... but it looks like I'am stuck with a very unstable system now, as I'm getting crashes as soon as I put the Amiga on any workload. Let me detail what I tried:

* Before upgrading to GOLD 2.9.x: everything OK.
* Flashing GOLD 2.9.1 x11 + Coffin r51: lots of crashes and reboots. Maximum time the Amiga was able to operate without crashing: 1 minute.
* Flashing GOLD 2.9 x10 + Coffin r51: quite improvement in stability, but still unusable. Maximun time the Amiga was able to operate without crashing: 5 minutes.
* GOLD 2.9 x10 + stock Amiga OS 3.x: way more stable than Coffin, but it will crash as soon as I put heavy CPU usage on it.

My system config:

* Amiga 600 rev1.5
* Vampire v2 600, from Majsta first batch on Amibay.
* A604n + Indivision ECS + RTC + RapidRoad USB.
* Sum A600 USB Keyboard adapter
* Powerful power supply.
* Usually I have a PCMCIA network card attached, but I put it off for the stability tests.

Any hints? I feel like somehow I lost my Amiga on the upgrade :(

I think your vampire needs the cap mod.

Reviewed the forum and it looks like it could be the problem. Time to visit the components store.

For the record, it's this simple mod :

Please report back once you've done it.

Reporting back! I completed the cap mod and my Amiga is stable again, regardless of using Coffin or stock Amiga OS. I have been playing Warcraft II (ShareShifter) for about a hour and running Quake demo for about 2 hours without any problem.

You rocks guys, thank you so much!

By the way, I have left flashed the Gold 2.9 x10 core (x10 is more than enough speed for me). Why the x11 one is 2.9.1? Does it have any feature 2.9 doesn't?

This is one has more serial numbers to enable the recently registered cards.

Fairly simple, thank you all for the help :)

  They are, on those you need to make sure to get them in the right orientation. I think using large electrolytics are likely overkill and I worry about odd power situations that may dump current into the board or the Amiga.

I just went with what Gunnar suggested, by stacking another surface mount cap on top of the existing caps.  a 22uF 0805 sized ceramic cap. stated here 3 posts down: CLICK HERE
