I've only tried them with the risers, I'm not certain that the DIMMs will fit in the slots without the risers?
I don't have a DS10L, but from pictures on the web I assume the risers just rotate the module orientation by +/- 90 degrees and the modules should fit fine into the sockets without the risers. Of course the hood won't close then, but it's just meant for testing the modules (1) without the risers or (2) with the known working modules. If one or both 512 MiB modules are defective case 1 should give the same symptoms (beep code and no POST) - I just want to rule out any problems with the combination of the risers and the 512 MiB modules. But case 2 might actually make the machine do a POST and just deactivate any defective modules - which could then be checked in the SRM (assumption). At least for the DS20E this seems to be supported (see "Memory Features" in the DS20E technical summary
), it isn't mentioned under "Memory Features" for the DS10
Other ideas: (3) Have you decoded the beep code (the AlphaServer DS10 User Reference Card
lists some) and (4) what does the RMC say when the machine powers up? The RMC should emit some messages on the first serial port (default configuration) as soon as power is applied to the machine and when the machine is started and detects a problem, the RMC might also emit some messages (assumption). You can find more information about the RMC in the AlphaServer DS10 / DS10L, AlphaStation DS10 Console Reference

I believe the 1 GiB limit is just because only a maximum of two modules can be used (and only in combination with the risers) in this machine when the hood is closed because of height restrictions and 512 MiB was the maximum memory module size available or supported at that time. I don't assume that the other memory bank is deactivated in any way.

Your decision, of course.
But if you ever try to diagnose this again, it would be interesting to know what you found out then.
