Windows 10: Will Free Windows 10 "Upgrade" work with Clean Install (CMPXCHG16b)?

Alright, I won't do that anymore, BunnyJ. I promise. You had me worried there for a minute! ; P

 

All good. And again.. best of luck with Win10, oh and have a good day.

Thanks, you too!

 

Hi everyone,
Just thought this might be interesting to some people: I am typing this from Windows 10, the final release, from an old Opteron system that was working on 8.0 (but failed the 8.1 update test). I did an inplace upgrade to Win10 32 bit and all is working well so far. (I downloaded the iso, burned that to a DVD and installed an upgrade from the DVD within 8.0).
PS. I have not tried a clean install yet.
PS. It did not run any assistants
PS. It gave me a new key that I could now use to try a clean install (am using a local, not a MS account)
PS. I have 8gb of ram but pulled 4gb out since 64 bit is not an option. I know it is not ideal, but it is fast enough on 32bit since memory management is so much better than on Win7. So I'd much rather run Win10 32 than Win7 64 since that was unstable with NVIDIA graphics.

I have an old AGP card, Nvidia 6200, I downloaded the latest Nvidia drivers (390 I believe) and those worked.

My specs:
Tyan Tiger K8W
dual 250 Opteron
Nvidia 6200 AGP
Raptor 36gb WD

For the record, the system feels faster than a recent quad core build with 4gb of ram and a samsung Evo 850 120Gb SSD! So there is life in these opties yet!

 

FYI banger, Pentium 4s are NOT dual core. they're single core only but later generations of Pentium 4s were dual threaded (aka. hyper threaded) [the "Prescott" & "Cedar Mill" series were HT]. I know because I own certain versions of those Intel Pentium 4 CPUs such as the 661 (3.60Ghz) & 641 models (3.20Ghz). If the hyper-threading feature of those P4 CPUs are enabled in BIOS setup, Win10 will treat the CPU as two "virtual" cores but not they're not true cores. Run the CPU-Z tool on your Pentium 4 and it will tell you how many "cores" it really has.

Pentium Ds on the other hand are true dual core CPUs. I also have such CPU - an Intel Pentium D 945 (3.40ghz)

 

You *might* be able to access all 8 GB of your RAM, even with the 32-bit Windows 10 variant that you have installed. If you enable the PAE flag:

By the way, many of the Northwood Pentiums had Hyperthreading (HT), as well. I had a Northwood P4 that ran at 3.4 GHz stock (512 KB L2 cache, 8KB trace cache). Ran Windows 7 (32-bit) and Ubuntu Linux (dual boot) like greased lightning.
