Old 2.8ghz Xeon only runs at 2.8ghz

[Ghastly Xeno]

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.

Turbo boost did not exist in 2005. If CPU is 2.8ghz, then it will run at 2.8ghz.

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?

Those early 64 bit chips were junk. You could be limited by ALL Kinds of things, mostly the system board in a 690

Is it this one?

Turbo boost: No

Instruction set: 32 bit

 

My guess regarding the issue with 32 and 64 bit. Is that Windows 7 64 bit, has the ability to handle 64 bit data, but does not actually require a 64 bit capable CPU to run itself. While windows 8 and up, actually requires a 64 bit capable CPU in order to even run. I'm not even sure why you would want to install 64 bit windows 10, as it serves no actual purpose. You cannot exceed 4GB of RAM, and your 32 bit CPU would not be able to process other 64 bit software.

Likely needs new thermal paste

Talking about 64 bit instruction sets... AMD was the first to release 64 bit instructions sets (and what we use nowadays is built on that), and intel tried to come up with their own; the dreaded IA64... older operating systems had support for IA-64, but that has gone the way of the dodo as AMDs setup became prevalent, which is why windows 8 and upwards no longer have such support...

That operates with a 400MHz FSB. Dell product page lists 800MHz FSB.

 

This is closer: https://ark.intel.com/content/www/us/en/ark/products/27078/64-bit-intel-xeon-processor-2-80e-ghz-2m-cache-800-mhz-fsb.html

 

Still need one that supports HT though as neither of these do. Could be a custom part for Dell.

Windows 8 x64 and later will not work on a chip that old because (if memory serves correct) they require security-related shit that Netburst never had. 32-bit probably only works because that branch of Windows likely does not require said security shit.

 

And the reason it just runs at full send all the time is likely either BIOS or Windows related, since the 7030 does have SpeedStep (obviously not Turbo Boost because that wasn't going to be a thing for quite a few more years).

Intel-64, and not x64... shaaaaayt

I don't think it has proper modern 64-bit support.

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.

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.
