Ghastly Xeno

I thought the security instructions requirements that were required in versions after the anniversary update applied to both the 32-bit and 64-bit versions, but seeing as how I just updated it to 1809 today, it seems you are correct. So looks like I'll be stuck with 3.1gb of RAM for now. Once I get a Dell 5100 from a friend and use its motherboard in the 670 with the GTS 450, I should be all good. It has a Pentium 4, but I should be able to install my spare Core2 Duo E6550, which will support Windows 10 64-bit hopefully, as it was released in 2007/2008 (forgot). After all is said and done, this 1 core hyperthreaded processor will be replaced by a true dual core. After seeing benchmarks online, light gaming is also possible.

This machine supports up to 16gb RAM when a 64-bit OS is installed, and, when I was testing Windows 7 64-bit, I installed 64-bit Java, so this is indeed 64-bit.

Then how about the problem with 64-bit Windows 10 not working, but 32-bit Windows 10 works, despite it being a 64-bit processor?

My friend was going to throw away his old Dell Precision 670, but I managed to snag it from him before it hit the dump. It has a one Xeon 2.8ghz processor in there (One core with hyperthreading) and a GTS 450 (CPU bottleneck is real, I have no idea why he upgraded this machine with a GPU that came out 5 years after it). I'm going to be upgrading the pc, mainly just keeping the GPU, but while I still use it, I'm wondering why this old Xeon, probably from 2005, is stuck at 2.8ghz. The problem isn't that it won't hit it's max turbo, it's just stuck at 2.8ghz. And so, it doesn't take long before it heats up and the fans rev up. It idles at 65c, but because the clocks don't go any higher, it never goes above 75c. I'm just asking, is there a way to get it to not do 2.8ghz all the time? Also, is there a way to install Windows 10 64-bit? I can install 64-bit Windows XP, 7, Linux (Lubuntu), and various other 64-bit OS's, but not Windows 10, 8.1, or 8. However, I can install Windows 10, 8.1, and 8, as long as I'm installing the 32-bit versions. How come I can't install the 64-bit versions of these, despite it being a 64-bit processor? Also note that I have to install the anniversary update from 2016, as newer versions of Windows 10 no longer supports Pentium 4 CPUs or CPUs based off of it due to missing instruction sets.
