Hi- I'm looking for RAM- no longer supported PC, so an OEM part number would be very helpful.

ProDesk 400 G1, S/N [Personal Information Removed]

Currently, a single 4 gig ram stick 7Q1515  PN 698650-154

 

Hi- I'm looking for RAM- HP no longer supports this PC, so an OEM part number would be very helpful. The RAM for this series varied by processor, in this case it is an i5 4670 quad core.

 

I have the OEM # for a 4 G stick (7Q1515  PN 698650-154) but I really would like to find the corresponding 8 gig sticks. Can you help?

You should be able to upgrade to 18GB (2 x 8GB) max using the following compatible RAM

I appreciate your response. What I keep running into doesn't make sense. I've tried five rounds of off-brand/generic RAM I purchased from reputable resellers (A-Tec, etc). What has happened when installed the RAM is this, Instead of going into the usual Win10 boot screens, I get a DOS-like screen that tells me "The amount of RAM has changed"  and prompts me to hit F1. Then:

A- the machine freezes or,

B- I get five beeps and the cpu starts to overheat with no other symptom.

 

I've tried installing the RAM in all possible combinations. New 8 G in either slot (I only have 2 slots), 2- 8 Gig, the OEM 4 Gig with the 8 Gig, and so on.

When I go back to just the OEM 4 Gig stick. the machine boots up normally.

The HP documentation is useless here- the Memory section refers me to select RAM by whatever combination of MOBO and CPU I happened to have, in this case, an i5 4670 (Haswell)quad-core on an Intel Motherboard 718778-001 718414-001 #3530,  and the documentation stops at this point.

So, I'm aware that Crucial makes a great product, but since the OEM RAM is the only RAM that works so far, I'll try that.
