Slowest SuperPi scores ever

[dchard]

Lowest SuperPi score ever.

A few days ago I dumped out an old Compaq computer from the rubish.
"It should contain some valuable parts" I tought.

It's an old Compaq 4/33S compuer:

- 33MHz 486 Intel SX CPU (without any cooling sollution)
- 45MB EDO RAM (70ns)
- 203MB HDD
- 1,44 Floppy
- 100w PSU
- No co-processor

Under a few hours I put a 3.0 Debian woody to it, with kernel 2.2.20.

Then the Super Pi test begans.

I ran the 16K test on the system:

Calculation time: 6691,190 Sec. (with a 3200+ it takes ~0,3 Sec. without OC)

Here is a picture to validate:

I cannot found any lower SuperPi score ever, but if you have one, post it here :-)

MOD: the 1M calculation should take up to 5 days (~4,91) to complete. If I have some time, I will run it.

[kiwi]

Run 32M :D

[cMw]

jesus 32m would take forever kiwi hahaha


thats definitely a slow ass time though dude :rofl:

[LenniZ]

Nice. A real conroe-killer. (if higher is better)

[Repoman]

I thought my 2 minute 1m on 900Mhz athlon was bad

Definiately :)

I would like to see 386/286 and XTs. Now that is one old piece of hardware :) Or even mainframes from 80s :D I worked myself on 286 and XTs, it was almost 20 years ago. They had around 256-1024KB RAM :D

[InSanCen]

Lemme get my 386/40 back, and I'll fire it up... will smoke your 486/33, guarantee it.

32M should be good for a laugh though, I'm game if you are:D

Would use the Apricot Zen Xi, 286, 512K, Monochrome, but it hasn't got the Protected Memory mode... can't see it running anything really.

Used to smoke people with that rig, it's in my sig...
I suddenly feel very old

[dchard]

I am sure that there is slower computers than this, but to get a score, you need to fire it up with a working os to calculate pi. :)

In this area I recommend the 16K calculation to use for the scores.

And yes, lets the game begin :D

If someone brake this record, I will hopefully find a way to get an older and slower config for a nex beat :cool:

Dchard

Oh and about 32M: I think that I sooner get a blackout than I can finsih a 32M calculation with this machine :-)

[Scarlet Infidel]

Is the rule no underclocks allowed? Stock speeds all the way id say.

[DeltZ]

omg..."hurry up" and do 32mb!

that would be obscene:stick: :slapass:

[ent]

Linux Super Pi is about 25% faster than Windows one :D

[Qkjhfhaiguihfma]

if i calculate 16k digits by hand do i win?

[X3non]

if i calculate 16k digits by hand do i win?
LOL.. :D

[thunderstruck!]

No cooling solution? Wonder what temps were.

[dchard]

No cooling solution? Wonder what temps were.

Interesting, but not too high: about 60 Celsius when run at 100%.

Yes, the rule is no underclocking allowed. These are stock values. (anyway I cannot underclock this sstem, because it's BIOS cannot changeable, I cannot set any value, neither with jumpers).

Of BTW: originally there was 16MB of EDO in it: I have some stick from my old school, and put it in for the linux to work a little faster. (an because there is no space for Swap on this HDD)

Another funny thing: there is no slot closing mechanism on the slot.

"Linux Super Pi is about 25% faster than Windows one"

Yes, but win 3.1 (or below :D) are not supported by Pi. BTW: an NT4 should be run on it, but if the 70MB linux distro setting up about 2 hours... I don't wanna wait that time, if not necessary :)

Dchard

[CompGeek]

lol, go guys go!

[realsmasher]

what if i run my old on win2000 or something, put prime in background with priority "realtime" and then calculate 16k ?

allowed ?

if yes, i'll send him into a 4 week 16k run :banana:

[RyderOCZ]

Slowest 32M I have seen so far is over 38 hours:

My old result, done in March 03, with a compaq contura aero laptop
CPU: 486SX-33 (without fpu, lol), 20 megs of ram.
Time: 1M - 46h 56m 06s = 2816min 06sec = 168966sec :D

http://pillemati.cafe.ee/~kalle/pents/486_superpi.jpg

also ran hexus pifast with that monster..

742583.24sec = 206.27h = 8.59 days = 1.22 weeks :D

My P2 Lappy 400Mhz does 1M in about 5 minutes. 256 ram!

[InSanCen]

I meant that my 386/40 (8mb) will be faster than your 486/33:D (First time I said that was a looooooong time ago)

Doubt I could get a Slower time off it if I run a Linux install straight off.
I'm sure I can get Win95 on it, that would do it...:D spent ages trying to prove it could be done.. have to dig out the old switches, I seem I remember I got it on there via Switches on the Installation CLI... dunno really, been such a long time.

anyway..

Spoke to the Friend who has it. We'll see what we can do. If it's all still working, we'll fire off the whole series for ya! You might want to put this thread on suscribe, a I suspect 32MB will take a short while, (We may even see AMD retaliation against Conroe before it finishes :D)

[Bbq]

Toshiba Satellite pro 4600
900mhz p3-m

17 minute 1m

don't even ask how long for a 32m.

[SMa]

Who will be the first one to do a week (168 hours) for 32M :banana:

What happens if Prime & SuperPi are ran together? Would be much much much slower.

No, no, no.

Thats not allowed to slow down the computer with other program loading.

That way with an endless cicle I can get much much worse score with my 486SX.

Please play this fairly. It cannot checked so this depends on the player's conscience.

In my test results no other program running background that artifically slow down the system for worse results.

As I said: the 1M on this shlt can take up to five days, i don't really wanna run it.

Please use 16K test in this slow area to determine a score. You don't really want to wait that time till 1M completed on a computer like this. :D

[InSanCen]

Agreed, to a point.

don't run any proggies to slow it down. just a Basic OS install will do (Win95 on an 8MB 386? Suppose that's pushing the envelope a bit. I'll lookee for a Linux install, see if I can get my head round it).

16K to show some numbers, anything longer at your own discretion
But I'm still up for running 32M...:D

organising getting my 386 back. Fires up still:D
The Apricot 286 does too!

[caater]

As I said: the 1M on this shlt can take up to five days, i don't really wanna run it.

as you have the same cpu as mine was, it should take 2 days max.. and linux version will complete it even faster..

I have Cyrix 100Mhz lappy, but spi are not running, just errors.
I got P133, and OC friendly s7 board, with 256MB ram. Will buy 200/233Mhz MMX pentium for this machine :toast: Oldscool, here i come.

[ewitte]

Time to break out the P133 laptop I have.

[dchard]

Time to break out the P133 laptop I have.

I have one too, I'll run a test on it.

Dchard

Oh by the way: OK, I'm in game: first I run the 1M on SX, than 32M, an d also on a 133MHz P1 laptop with 32M ram, and win98 on it but on this just an 1M.

[over@locker886]

Welcome on XS my friend's:D Wait 1M and 32M:toast:

[dchard]

I done with the 1M superpi test on a P1 133MHz laptop with 32MB RAM, and no L2 cache, Win98

1M Calcualtion time: 53min 03sec

Validation picture here (http://prucsi.clan-hq.org/cfos/laptop_pi.jpg)

For the test 1M and 32M on 486SX I need to borrow an UPS :D

The game is on.

Dchard

MOD: for users who get errors on old machines with win95/98: use the original superpi:

ftp://pi.super-computing.org/pub/exec_windows/super_pi.zip

[Kasparz]

I ran 16K on Cyrix lappy, 75Mhz actually and 24Mb ram, w95. 16K time 7.26m
I ran spi on s7 rig too (P133 256MB SD-RAM w2k) underclocked to 75Mhz(50FSBx1.5), 16K 13.059sec, and overclocked to 188Mhz(62x3) 16k 6.059sec. I really dunno why Cyrix lappy are too slow. I started to run 1m now, but i will not finish today :D

[dchard]

It seems, that an old 386 33MHz AMD computer with almost 4MB of RAM should come not far, so the 1M and 32M tests on 486 SX will be delayed.

This is a borad integrated one :D

I think the 32M on this it takes more than two weeks, far more :D

With the 486SX the 32M with precise calculations from 16K results: it takes ~ 1/3 month.

Dchard

[Big SturL]

What would be nice to see is how slow a modern machine can go, due to crappy software. My mothers laptop which has a 1,7GHz Pentium M and 256MB ram, uses like 2.5min on 1M.

[Kasparz]

OK, who wants SLOOWW times, use w95. 16k on w95 7.26m, 16k on w98SE 52sec. Same config.

[dchard]

Hi!

386 40MHz AMD cpu, 3712KB simm ram, 200MB HDD, VGA with 512KB ram (ISA), Win95 Floppy Edition(!).

Original SuperPi 16K running. :D

Why Floppy Edition? Because the CD version crashes with "Memory control error" before it can start the file copying stage in setup. The CD is fine (I setup systems with it).

A 486sx doesnt even have a maths coprocessor so its a bit unfair.

We had an 086 till recently, it was a full system & I used it to print documents off. I actually sold it on ebay for £40 :D

8.66mhz I think it was, I used to go make tea and a sandwich while it started so cant remember now. We even had a couple games, tetris 3d and double dragon! 512k was its total memory or maybe half that, but is that even enough to run superpi? Only had a 5.25" FDD too but I think I would have used a nullmodem cable and zcopy to transfer the program.


The oldest machine Ive used was a Wang machine (1970's?). Maybe it was called that because of the 1 foot long floppy disks it used :hrhr:

[dchard]

"is that even enough to run superpi?"

No. Not because SuperPi, but you cannot run a proper OS to run Pi (win, or linux).

And I'am in trouble too: SuperPi can be started, but hangs immediately, after I start the 16K calculation. Interesting, because win95 is running quiet well. I think I need a little ram. I can buy 5-6 pieces for just 0,5$ :D

Next week I will do this, and will try again.

Dchard

[Celeron Gamer]

My 486sx/25 can be set to 7MHz in the BIOS, I don't bother running Superpi with that :)

u overclock too much lol

[Khenglish]

Hey does anyone know how to mod a graphing calculator to make it calculate past 10 decimals? I think the 4mhz 8bit z80 in the Ti-83 and 84 will take the crown as the slowest calculation. I'm worried that the batteries won't last the days to calculate even 16K.

[ANP !!!]

LOL.. its like we are all back in old times. when P series was going to be launched. God Dammit those were the times.
