Hello,

I purchased a T320 a couple days ago from an ad on craigslist... (Please don't blast me for this - first time I'd ever done that, and last time.  Lesson learned)... to be used as a fileserver for my home.  It came with a single @E5-2440, 24GB Ram, H710, DVD, and (7) 500GB drives. I paid $600 and figured for what I was getting, it'd be cheaper than buying new or building from scratch.

Ever since I got it home, it's given me nothing but troubles.... well almost.

LCD panel keeps throwing: VLT0304 CPU 1 PLL PG voltage outside of range.  Reseat CPU

This happens so sporadically it's not funny.  Sometimes, it will throw the error and power cycle during POST.  Sometimes, it will throw the error while I am in BIOS.  Sometimes it threw the error while I was trying to build the RAID (H710 ctrl-R).  It managed to stay up long enough to get Ubuntu 18.04 LTS installed... then the error again and power cycle.  I managed to get the latest IDRAC and BIOS updated in between all this, hoping it would solve the issue.

Throughout all of this, I have unplugged,  drained the flea,  unplugged everything from the motherboard,  removed the CPU,  removed the H710,  put everything back, and powered back on... The first time I did this, it came up without issues for about 30 minutes.  The second and third time, didn't seem to help much.

Then all of a sudden, it decides to stay up and running without any issues for hours on end.  It managed to stay up for almost 24 hours (overnight), and I've been on/in the OS, tinkering and setting it up, all day without any issue.

I pulled out one of the hot swaps (just to get a model number off the drive) plugged it back in... about 30 minutes later, i got the LCD error again... 3 times now within the time it took me to write this.

Each time this has happened, the SEL shows a bit more:

CPU 1 has a thermal trip (over-temperature) event
CPU 1 PLL PG voltage is outside of range
The system board PS1 PG Fail voltage is out of range

When I run the Hardware Diagnostics, everything comes back green.

I guess I need to know the following:

Is this a bad CPU ?  or a bad motherboard?  or a bad power supply (350W)?
Is this happening because I have it plugged into 1) the wall and/or 2) surge protector power strip,  instead of a UPS  ?
If I need to replace the motherboard, does DELL sell them new and how much? (I can't seem to find anything other than "refurbished" on ebay.

I really don't want to call it quits on this just yet, since I've only had the machine a few days now... but it seems if I look at it wrong, it craps out.

Any help would be appreciated.

Thanks,
Michael
