for sure, hope to hear your good news.

Have a good one!

Erman,

I am sure others have "real" issues with their Servers, so I appreciate you taking the time "chatting" with me. It keeps my spirit up, ha ha. That said, I just ordered a PSU I found for a really good price. I don't think it is the PSU, but it always bothered me that I never replaced the broken one. (I had two).

After that, I might buy a motherboard. I saw a good deal for 110 euro. Unfortunately, it is a private seller so I can't send it back it doesn't fix the issue. Don't like doing that anyway.

Thanks.

Thanks, you too! I keep you posted.

One more thought:

The last thing I saw before my T620 died completely was:

DDR3 Training Failure - FPT - Write DqDqs DIMM A1

Memory Training Failure Detected. Failed  Write DqDqs DIMM A1

Since the T620 had died, I had no chance to switch RAM sticks around to see if it is the RAM itself, or the Slot that is defect. Now that I have taken everything out and only left RAM in Slot 1, and Slot 1 could be defect, can I use another Slot as my "minimum boot configuration" Slot? Lets say Slot 2 or so?

Thanks.

Hi, unfortunately no if T620 has one CPU then it needs to populate DIMM_A1 for the minimum to post process. You can try with a known good DIMM on the A1 slot to figure out slot is working or not.

I see. What about having two CPU's installed. Can I use DIMM_B1?

Thanks

Chris,

Putting RAM in dimm A1 and B1 did the trick!!! My T610 did boot again. YEAH!

Since I had taken everything out, including the GPU, PERC controller and RAM, the front panel is telling me that there is a "problem" with the connection to the hard drives. Makes sense [since the PERC controller is not there).

However, what do I do from here? I am afraid to just hold the power button and turn the system of, but I guess there is no other way of doing it other than that!?

I would go ahead and plug in the GPU first so I can see what's on the screen. 

After that, plug in PERC so I hopefully have a running (OS) T620 again.

Then test RAM by RAM, but how? In which order do I go? Now dimm A1 and B1 are plugged in. Do I then add dimm A2, then B2, then A3 and so on?

Thanks!

Erman,

thanks for the reply. Since it does not show 32GB and 48GB using 8GB dimms, I figured I just add two, to each channel. Currently I have two 8GB in A1 and B1. So 16Gb. To add two more I would do A1, A2 and B1, B2, correct? 48GB would be A1, A2, A3 and B1, B2, B3, right?

Or do I plug all of them in at the same time again and see which dimm shows up as failure? And then simply take those two out?

I also wonder if I have to disable onboard GPU when using external GPU? I am using the onboard one right now, but I can see my NVIDIA in device manager.

Thanks.

Hi,

I thought I can just add one dimm at a time to see which one is defect, but I guess I have to a add a pair since I have two processors.

GTX780Ti. I remember ordering a GPU cable kit for the T620 when I bought it, so Dell must have been planning on people adding GPU's.

Thanks.

Hi, yes you need to add a pair of DIMM due to two processors. 

I found a power GPU cable but I couldn't see a GPU kit part number. by the way GTX780Ti not officially supported. You may encounter an issue. However, it also doesn't mean it won't work at all. 

Erman,

I thought it was a "kit", because there was the cable and something else. Like a GPU bracket to secure it. Doesn't really matter...

My GTX 780 Ti always worked with no issues. Ever since my T620 was acting funny, the GTX seems to act funny as well. I see it in the device manager but no signal comes out of it!? Anyhow, that's a different issue, for another forum. 

I would still like to know if I have to turn the onboard GPU off!?

Thanks.

Hello navissa,

Since Dell has not validated GTX 780 Ti you may need to try trial and error.  Try it with it enabled and disabled.

I can provide this for your review:  GPU Card Installation Guidelines

You may check this post for their experience. Please don't post in that thread as it is an old one. I just wanted to provide for example.

Charles,

Thanks for the fast reply. I am going to just disable the onboard GPU and see what happens. However, the only concern I have is that if my NVIDIA does not work, how would I be able to see the BIOS if the onboard is disabled, ha ha. 

I think I could just take the NVIDIA out, and the onboard would automatically come back on, right? 

Thanks.
