Recommended Posts

Uhm, I cant even reinstall it the darn machine. Just hangs under the installation.

To rule out a possible instability of the LV 4GB Hynix coupled with your 1.5V Kingston (which by the way Kingston lists as compatible with the T20) try this:

 

Remove just one of the 8GB DIMMs and use it with one 8GB and the 4GB and see if you get the same behavior.

 

Does the Hynix overheat at 1.5V?

Run memtest. No issues!

 

It works fine with only one of the KTD-PE316E/8G sticks.

 

Correct me if I am wrong. First populate the white banks, and then the blacks?

Yes. The sockets are like this (counting from the CPU to the front bezel): 3, 1, 2, 4.

Channel A is 1 and 3, channel B is 2 and 4.

So the order would be 1, 2, 3, 4 when populating the sockets (1, 2 and 3 in your case, 1 and 2 with 8GB each and 3 with the original Hynix 4GB).

 

Also check your BIOS log entries. Is there any memory related message besides "the amount changed"?

Do you get any beep pattern on POST?

They will, but if you're planning four of them to max it out, you should really get the KTD-PE316ELV/8G, which are 1.35V.

 

Have you actually installed and tested the KTD-PE316ELV/8G? I'm planning to go to 32GB in my T20 but haven't seen much real data on memory for it.

Been running Memtest (http://www.memtest86.com/) for five hours, no Errors.

No Beeps att the startup. And Bios register all memory fine. No logenteries.

Been trying bank 1 and 2 (whites). It hangs

Been trying bank 2 and 4. (white and black) It hangs.

Beem trying bank 3 and 4 (black and white). It hangs.

Been testing memory 1 alone, and memory 2 alone. It works fine.

Memtest looks like this. And yes, I just ran it for showing the memory specs:

 

I also ran the Dell heath check, I think it was called. That is buildinto the BIOS. And that check pass to.

Have you done the single test with both sticks of 8GB RAM. It could be that 1 of the sticks has a small issue that only shows up in certain circumstances. If you haven't done this, or can't recall for sure, I would stick a label on the two 8GB sticks and then try doing an install with each one separately, to see if one of them hangs.

 

The other thought I had is that perhaps it's ESXi that's complaining, and that's why you're not getting errors with anything else. You could test this by trying to install some other OS; see what happens.

The correct pairing is 1+2 (whites) for the two Kingstons.

 

If Dell's diagnostics passed all of the memory tests it has to be something else (software related). What exactly is that hangs?

I thought that the two Kingstons were okay, but not when combined with the 4GB Hynix.

 

By the bill of materials, the Kingston appears to be KVR16E11/8.

 

Like ikon sais, try some OS without ESXi.

@Taffeys No, I have not installed and tested the 8GB LV Kingston, but that is first on my list of memory for the T20.

I did tested one G3220 T20 with a 32GB kit (1333MHz non-ECC) I had on hand.
