Underclocked P2. 256MB of RAM. Windows 7

May 17, 2010 at 13:41:07
Specs: Windows 7 x64, Dual-core Opteron 185 @ 3.2GHz, 4GB
Sh!t happens when my Sundays get too rainy.

Here it is: Windows 7 on one hell of a slow machine.

Final Specs:
-300MHz Pentium II underclocked to 180MHz (60x3)
-256MB of 60MHz SDRAM
-160GB hard drive
-GeForce FX5200 @ AGP 2x

Notes:
-I also tried getting Win7 to work on a Super 7 board, first with a Pentium MMX 166, then with a K6-2 300. However, the OS would hang before the main installation screen. I guess the Pentium II is the slowest CPU Win7 will tolerate.

-To satisfy the installer, I used a Pentium III 600 with 768MB of RAM. Same motherboard. After the OS installed, I slotted in the P2 and its 256MB of RAM.

-I couldn't get Aero to work with the P2; when I tried enabling it, I received a BSoD. However, Aero worked fine with the P3-600 (same motherboard and RAM). It appears that W7 Aero requires a CPU with SSE.

-Win7 would not boot with less than 256MB of RAM installed.

Computing.net is also up and running in IE8.

Above that is a CPU usage graph. What's interesting is that Win7 with Internet Explorer running only uses ~40% of the CPU. Under Vista, the same CPU was constantly pegged at 100%, without IE running. This shows how much faster Windows 7 is than Vista. As for physical RAM, Win7 uses 180MB of it, which is actually around what Vista used.

CPU-Z shows us that a 180MHz PII running Windows 7 will in fact play a 1080p, 34 mb/s M2TS movie off the file server. The catch: you have to watch it at an exhilarating 2 frames per minute. Really.

That's it for now. The machine is quite slow, but it's actually not too bad, considering the specs. The old rig runs Windows 7 at least 10x faster than Vista. Interestingly enough, it was not reduced memory usage that allowed W7 to outperform Vista, but greatly reduced CPU overhead.

I won't be taking the machine apart just yet, so if any of you would like to see more, I'll boot it up when I have the time.

Couple questions...

Why did you underlclock?

How do you consider 2fpm as a movie; slide shows are faster. :-}

Another question - 160GB HDD on a board that old?

"Why did you underlclock?"

I'm trying to set a new low. :)

"Another question - 160GB HDD on a board that old?"

The BIOS doesn't report the correct size, but Windows sees it all. It was the only spare drive large enough for Win7.

I doubt you plan on keeping the system setup this way, but if you did, wouldn't the data evetually become corrupted due to the board/BIOS not supporting 48-bit LBA?

Probably, but I doubt that anything bad would happen under the 137GB mark.

I'll be taking the system apart in a few days.

Just after the movie credits?

Forgive me...just couldn't help myself.

LOL.

But I'd also like to watch vol 2, so

Underclocking, sweet!

I really don't see why the Pentium II will run Vista and the Socket 7 machines will not. I could see why if the P-III would run it and the P-II would not (SSE).

Have you tried to run it on a Pentium Pro machine? I have one sitting right here, OCed to 233mhz, I am so tempted now!

Hey, see if it will work on a Cyrix M-II, lol!

If I install Windows 7 on Intel P3 866 Mhz,256 mb RAM, will I be able to efficiently run programs like Photoshop CS,MS Office 2007,Quark Xpress 8,etc(without the computer hanging every now and then)?

One word, No. Your computer is way to slow to run programs such as photoshop without hanging, especially with only 256mb of ram on Windows 7.

jackbomb was just playing on a day when he obviously had nothing better to do. He's probably still trying to watch that movie.

"I could see why if the P-III would run it and the P-II would not (SSE)."

Aero Glass/desktop composition under Win7 seems to require SSE. The 600MHz PIII had no problem running it, but the PII crashed to a bsod. Makes me wonder how a 1.4GHz Thunderbird Athlon would handle it. Would it run Aero using 3DNow? Unfortunately, the only K7 box I have left is a Barton 2800, which does have SSE. It runs Win7 w/ desktop composition beautifully.

"Have you tried to run it on a Pentium Pro machine?"
I had a 180MHz Pro a few years ago. Neat machine, but its performance left a lot to be desired. My P233MMX, SDRAM-based machine ran circles around it.

"He's probably still trying to watch that movie."
Nope, ended yesterday! :P

"Is it going to rain this Sunday?"
No, summer is finally in full swing!
