First of all, thanks for the program. Aside from this one issue, it is excellent, and it is very useful for keeping a quick eye on the memory status.

I've noticed Meminfo never shows more than 4GB use by an application. I'm assuming this is because it's a 32-bit program. Is that the case, and if it is, can you provide a 64-bit version? I see there's a post from 2010 stating that when a 64-bit Delphi compiler became available a 64-bit version of Meminfo would be, but that doesn't appear to have happened.

Hi Steven,

Thank you for your comments and your query on MemInfo.

MemInfo supports detection of memory above 4GB even as a 32-bit compiled executable on 64-bit Windows

In my own system, with 8GB RAM, I tested going beyond the 4GB and you can see MemInfo reporting correctly a physical memory in use of 5,38 GB:


I guess it must be something on your system.

Yes, we have a Delphi 64bit edition now, but I've not yet found a reason to compile it to 64bit since it works well as a 32bit app on 64bit systems.

MemInfo uses an internal Windows function to retrieve the current memory usage, so it's irrelevant if it's a 32 or a 64bit Windows.

Hope this helps.
Thanks,

I guess I should have been more clear. It does show total usage of >4GB, but per application it only shows up to 4. For example, my browser is using just shy of 7GB but MemInfo reports 4GB even for it.

Hi,

Sorry, yes, I did not understand that it was memory usage per application, sorry.

I've tried to replicate and I'm struggling to even go beyond 1GB in an application let alone 4GB. Any tip on how to make a browser go beyond the 4GB? What browser are you using? how many sites open?

Thanks,

André Santos

I'm using Pale Moon, which is a fork of Firefox which should, therefore, do the same thing theoretically. I frequently have 70+ tabs open, and sometimes 2-300+. For example, among others, I currently have ~90 Amazon tabs open, and without them even being loaded up (I just restored the browser and until I activate them they don't load) I'm at 1.16GB usage. Just open a bunch of Youtube, Amazon, Google Maps, Google Image search, etc tabs and you'll get there.
