copingNutria Posted February 13, 2022 Share Posted February 13, 2022 Hello, this is my first post here, glad to be a part of community. Currently I'm looking at Zbook 15 G3 with Xeon E3-1505m v5 for cheap and the only thing that makes me wonder is: Will it work with non-ECC DDR4 memory sticks? I'm not talking about mixing ECC and non-ECC, I have spare 2x16G Hynix sticks and planning to use it in that scenario. I am aware that HP docs says something like "just use ECC", but I'm curious if anyone had tried this. Link to comment Share on other sites More sharing options...

copingNutria Posted February 15, 2022 Author Share Posted February 15, 2022 Hey, thanks. It appears that official HP docs recommend ECC memory for Xeon. I'm just curious about possibility of that particular Xeon model in Zbook G3 to "non-officially" work with non-ECC memory too. Link to comment Share on other sites More sharing options...
Aaron44126 Posted February 15, 2022 Share Posted February 15, 2022 Sorry that I can't offer confirmation, but I think there is quite a good chance that this will work. I'm not so familiar with the ins and outs of the HP ZBook line, but I know that Dell Precision 7000-series works with both ECC and non-ECC memory if a Xeon CPU is installed. This is true for all generations where Xeon has been offered (6th gen - 11th gen). Intel supports it, so it seems like it would work with HP systems unless they went out of their way to block it.
