Re: HP Probook 4520s Memory upgrade to 8GB (2x4GB) Corsair Unsuccessful and Failed

[ Edited ]

I can confirm that the G.Skill RAM posted does work. An observation, if I may:

 

In relation to 4GB Modules, both of the Mushkins (996647 and 997066) that I tried (and failed) to use, as well as the one set of Corsair (CMSO8GX3M2A1333C9) all had 8 ram chips per module. The G.Skill has 16 per module. Perhaps this is the key, and affects the addressing of the memory in some way?

 

For reference, the G.Skill's SPD output is as follows:

Re: HP Probook 4520s Memory upgrade to 8GB (2x4GB) Corsair Unsuccessful and Failed

That could be, but it's odd that the specs are all the same. Just plain weird. As I said before, the guy at my store said he doesn't know why either, but sometimes GSkill just works. I've racked my brain trying to figure this one out, and HP doesn't have an answer for it either; at least none of the techs I talked to.

Re: HP Probook 4520s Memory upgrade to 8GB (2x4GB) Corsair Unsuccessful and Failed

Well, we may never know, that is until someone goes out and tries a different set with 16 chips per module :smileyhappy:

 

Cheers, everyone!
