24gb at Win7 premium, ramdisk question

[turbopixel]

Hello guys.

I am upgrading my ram from 8gb to 24gb. I know that the limit of Windows Premium is at 16gb. If I create a 8gb ramdisk, will be 8gb or 16gb left for Windows and applications?

Btw my main operating system is a Linux based one (Ubuntu 14.04). That is where I could need higher ram for video and photo editing.

Windows 7 Professional x64 has a limit of 192GB - https://msdn.microsoft.com/en-us/library/windows/desktop/aa366778%28v=vs.85%29.aspx#physical_memory_limits_windows_7

Oh sorry my fault. I meant the version Home Premium. Got confused with the versions. Thanks for correcting. I'll edit the title (if its possible).

To be honest... I'm not really sure. I did read that a RAMdisk will work to get past that 4GB limit on 32-bit versions of Windows... but on a 64-bit version I haven't been able to confirm whether or not a RAMdisk will work on a (Windows Home Premium) system that currently has 16GB of RAM. Some people claim it will should work while others claim it won't work.. but none of the people, as far as I can tell, have tested it out for themselves.. so they're just guessing.

It would NOT make any sense to buy Windows 7 Pro or Ultimate since the free upgrade to Windows 10 Home will allow up to 128GB.. so if you upgrade now the extra RAM will become available after the upgrade.

As far as creating a RAMdisk, I'm not sure. Just go ahead and upgrade your RAM and come back and post here as to whether or not you're able to create a RAMdisk.

I will test it, as I already ordered and just waiting. I just ask, because there could be something like best practices or specific bios/uefi settings or a specific tool, which would do the trick. I just wanted to prepare everything.

Anyway, I will report later.

OK... that would be great...

Sorry to tell, but I can't test it anymore. I've messed up things and some of my mainboards functionality is broken, like broken LAN adapter and USB3 and even my soundcard on PCI extension will not be recognized. I decided not to try things anymore and was in real panic.

I don't know if this is part of what the problems called, but I had 2x4gb ram with 1.35v and mixed them with the new 2x8gb 1.5v. Didn't pay attention to the voltage. And while starting and killing the power abruptly (because nothing worked), I think things gone wrong and its part of my own fault. Is this really dangerous for the board to mix 1.35v and 1.5v ram? Btw, I am using the new 16gb now and leave the old 8gb sticks unused.

I'm not exactly a RAM expert and most people say you should not do it. However, I have read postings from people saying it's ok if you're careful. In my Gigabyte (dual channel) BIOS, I've always manually entered the RAM's timings and made sure it had the correct voltage (1.5v). After I entered the values for slots 0 & 2 (channel 1) the settings carried over and duplicated for the RAM in slots 1 & 3... but I noticed I could also enter different values for the second pair... so I think some motherboards can handle different mixed ram... just as long as your pair them correctly into their matching slots and manually enter the correct timings and voltage for each set (my theory). However, this website has a lot of "purist" who are adamant that you should never do this or that or insist you will have problems. I currently have 16GB installed (4x4GB) but since Windows 10 supports more RAM I've been thinking of adding an extra 8GB of RAM to my system by getting 2x8GB modules and replacing a couple of the 4GB ones. I found a pair of G.Skills with the same exact latency and same exact timings so it shouldn't any problem.

As far as starting the computer with the wrong timings.. it does happen.. and it did happen to me once. I upgraded my BIOS (first time) and forget to double check the timings.. and my computer crashed since it reset my BIOS settings. I just re-entered the timings and everything was OK.
