Alright, I don't know if someone can help me here with this, I know someone else was having a similar issue here, but I don't know if it was ever resolved.
For the past month, I've had three modules in my Saturn, and all the dies have been working fine ever since I've gotten the upgrade module, and used fw 98.1.beta. 3 days ago, one of the dies died and won't stay on. I've put in fw 9.1.1 (the new one 'Orama linked to) and adjusted settings, but it only comes back on for a few seconds (maybe 10 seconds), and dies again. Also, if I use any other fw other then 98.1.beta another die turns off on another modules, and the worst part is, bertmod can never detect that dc/dc module, here's what I mean:

On the last board, one of the cores never show up (it never has), and the one that shuts off on any other fw is the one I can't see (the only reason I know this is because I used BFGMiner from bertmod and it showed that board only hashes at 108GH/s on any other fw.
Things I've tried:
1. I checked all the cables (power and data cable). I've got all the modules plugged directly to the PSU currently (bypassing the blue extension cables)
2. I've rearranged the data cables on different ports, I've also swapped cables between modules.
3. I've tried to let the module heat up to 88c to see if the die would come back on.
4. I've tried several firmwares: 9.9.1-tuning, 9.9-tuning, 9.8.1, 9.8.1beta (the one that works the best), 9.6.1, 9.5 and 9.4. I'm currently back on 9.8.1beta
I don't know what else I can try to fix this. Before I was getting an average of 425GH/s and 5920WU. Now I am getting 380GH/s and 5330WU. Anyone have any other ideas I can try? I don't know jack sh!t about linux, so if it involves anything to do with that, I would need handholding through the whole process. I would really appreciate the help.
Thank you all in advance.
P.S. Now that I think about it, that problem started happening the day after I updated to the new fw that 'Orama had linked to, that improves the hashrate for Eligius. Not sure if it have anything to do with it, or just pure coincidence.
EDIT 1:
I just tried it with having just that one module connected to see if maybe it was a problem with the PSU and this is what I get:

EDIT 2:
.... and not its back to the way it was... 0.188A output voltage... so its not a problem with the PSU. I've tried different pci-e cables.
