I apologize if this question is not appropriate to ServerFault, but I have been Googling for hours to no avail and Sun doesn't really exist anymore and I don't have a support contract with Oracle so I can't really ask them for directions...
Anyways, I was recently given a Sun Fire X4100 (not the M2), with 2 x AMD Opteron 254 and 4GB of PC-3200R DDR1 ECC RAM and I intend to use that for ESXi but I needed to upgrade the RAM first.
After checking the documentation I was able to find online, I decided to purchase 8 x 2GB DIMMs. Now, these are HP DIMMs since I couldn't find SUN ones, and they are from Micron, as opposed to the the Samsung ones currently in the server, but did a lot of research on DIMM compatibility and was not able to find anything saying these shouldn't be compatible, so I went ahead with the purchase.
They arrived today, I did everything the documentation instructed me to do (Power off the server, replace the DIMMs, clear CMOS, etc...) but they just wouldn't work. I power up the server, it shows a RAM error (the amber lights on the RAM slots) and doesn't even POST.
So I checked the ILOM logs and this is what I got:

I tried setting 2 of the old DIMMs in NODE 0 and SLOT 0 and 1 and 2 of the new DIMMs on NODE 1 on SLOT 0 and 1 which made the system POST but it would only recognize 2GB of RAM installed on NODE 0, even though ILOM shows that the 2 x 2GB DIMMs are indeed installed. And the faulty RAM lights were on for NODE 0 SLOT 1 and NODE 1 SLOT 1, which seems pretty odd to me.
I have gone through all of the basic troubleshooting I could think off, cleaned connectors, swapped slots, reset CMOS but nothing worked.
According to the manuals I was able to find, this system does indeed support 2GB DIMMs and the BIOS is updated to the latest version, so is the SP Firmware. So I'm out ideas, I'm hoping someone here has or has had this same system and is able to help me out with this issue...
Extra info on the labels that might be helpful: Old DIMMs:
Model: Sun (Samsung) PC3200R-30331-C3 1GB DDR PC3200 CL3 ECC Sun P/N: 371-0072-01 Single-Rank DIMM
New DIMMs:
Model: HP (Micron) PC3200R-30331-Z 2Gb DDR 400 CL3 ECC REG HP P/N: 373030-851 Dual-Rank DIMM
Thanks in advance for the help!
