Ok, Phil, start a thread blaming me just so you can post an uber-score :D

What is interesting is I was getting a 36sec time with the P4 2.8C @ 3.57GHz (255x14 with RAM @ 1:1). For raw crunching power, these A64's are very impressive.

XP1700(TBred-B) @ 2253 gives 62 sec... varying the ram/fsb speed had no effect on results?
/edit
down to 61 sec now, this is on a win98se machine... wonder if that makes a diff?

phil

2nd March 2004, 04:36

Something seems wrong there Tim. SuperPi was written when Win98 was in it's heyday. Are other benches showing correct results? I'd expect around the high 40s with your specs.

MikeTimbers

Tim,

check the memory settings. There is a huge differnece between running ram at CAS2 and CAS3. 62secs is way high for your headline speed.

Medic193

2nd March 2004, 09:55

I'm running close to the same system as Tim on one of my boxes. I got 1 minute 3 seconds.

MikeTimbers

2nd March 2004, 11:49

So how come my 1700 at 2400 (relatively small % quicker than 2253) manages 43 secs? I've found that high multiplier/low FSB is much worse than low multiplier/high FSB especially if the memory can be at low latencies.

I run 2-2-2-5 (@2.9v with no heat spreaders :eek: ) at 200MHz with a 12x multiplier. That gets me to 43 seconds.

zhotfire

3rd March 2004, 00:50

Hmmm... maybe the bios is lying to me and isn't applying the manual settings... I'll have to check that out. :confused:

zhotfire

6th March 2004, 11:37

An update... I dropped the FSB to 100 and ran at 2205 Mhz... got 1 min 15 sec. I'm wondering if the lack of variation on the high end is due to dual channel being enabled...? It is running on an NF7-S...
Anyone with an NF7-S and XP cpu want to compare apples to apples? LMK Thanks! :)

Only one mod... Vcore +5%
Never goes above ~46c full load
This is on air cooling :eek:

The headroom on this thing is amazing!
If you've been waiting... I'd say it's a very good time to upgrade! :)

Hey Phil, how ya been?

You have an FX55 rite? What clock speeds are you getting from it? I was going to go with an FX, but I wanted .09u so I went with this chip. The speeds I'm getting are about average for the winchester cores.

All the old timers know I'm a big ASUS fan, but they didn't make an NF3 939 board. I'm not interested in SLI or PCI express. This MSI board is a stable, and very fast board, but a major PITA to set up.

MikeTimbers

30th December 2004, 15:44

Very nice score Dustin. I've seen people with 2.9GHz A64s only getting a couple of seconds better so you've got a real nice system there.

Dustin

30th December 2004, 17:12

Very nice score Dustin. I've seen people with 2.9GHz A64s only getting a couple of seconds better so you've got a real nice system there.

That was my best time... I got varying 32 or 33 sec's. I Must be rite at the measurement cutoff (32.4 32.5). Too bad it doesn't measure tenths. One second is a lifetime to a CPU. Also, I do not know how sensitive Super PI is to HT, RAM speed, timings ect... Anyone running at 2.9 most likely isn't using a 1/1 ratio.

I know this isn't the rite thread, but I'd like some advice on water cooling. I know some ppl here have a lot of experience in that area. :)

MikeTimbers

30th December 2004, 18:31

Start a new thread. Both my systems are water-cooled and Phil and Martyn both have bucket loads of experience :p

pinman

30th December 2004, 23:08

48 seconds.

Celeron D 2.4 Ghz @ 3.7 Ghz.
Ram at 206 mhz.

Prescott runs a bit warmer than I'd like. But kicks butt for a super cheap cpu.

phil

31st December 2004, 09:37

Hiya Dustin, I'm doing fine thanks :). I am still running the FX51 and Asus SK8V that I was a year ago. It is watercooled using a Swiftech MCP650 12V pump, Swiftech MCW6002-64 water block and a Thermochill HE120.1 radiator.

Max core speed is 2.5GHz but at 200x11.5. I haven't had much luck with higher HT speeds but it is probably down to the registered RAM. I am about due an upgrade but am waiting for the New Year sales :).

hey guys i know this is a bit off subject but do any of you know where you can get SuperPi far a mac OS? i was running it on my old p4 1.8 running at 2.1 (air cooled) and i was getting over 1min :banghead: but my macs much more the machine for the job thanks

Wow, check this this (http://www.legitreviews.com/article.php?aid=178) out. Specifically where they show the SuperPI results on page two (http://www.legitreviews.com/article.php?aid=178&pid=2). That's a lot of crunch out of a 2.4 to 2.6 Ghz.

Its an article about running intel 479 processors on a 478 socket. Asus created a converter so you can run Mobile Pentium 4 on a regular socket 478 board.

Is intel finally emulating AMD with these Dothan processors? Lower power, lower speed, higher performance? Sounds a lot like the athlon 64.

21st March 2005, 21:22

Wow! Thanks for that link! Sarah and I both are running P4P800 SE mobos here, and I looooove quiet! Pentium M, low power and performance! Definitely want to check that out, even as just a "research project". Be fun to play with...

Hey Billy, I use an Abit IS7-E Motherboard. Same chipset. Does your MB give you a Power Mosfet temp reading? If so, can you give me a few details? FSB? Video card? Processor speed?

I'm running Celeron D 2.4 at 3.7 Ghz. Processor about 62 C, PWM about 63 C. Are you seeing similar temps on the same chipset board?

Wow, no I am seeing much lower temperatures. In my machine I have a 2.4C, on a 250 Mhz. fsb, for a processor speed of 3.01 ghz. Stock HSF and at default voltage. At idle the processor will stay around 36c, "system" which stays about the same. Full tilt I will hit 48-50 for the processor, and the "system" will go as high as 44. The case generally stay around 27-32. Ambient being 23-25c.

I have:
ATI Radeon 9800 Pro
2x512 Kingston HyperX 512MB PC4000 memory (dual channel)
120GB WD pata hd
Leadtek Winfast TV tuner
SB Extigy (usb)
Liteon 4X DVD burner
Antec Whisper 430 Watt PSU

I only have 2 extra case fans, on a switch and rheostat, but I only use them on low when I am gaming. The psu has two fans, but they don't make a lot of noise. Although "Whisper" is a name that does better for marketing than for reality. ;) But I like quiet, and this does passably well.

Sarah has a similar system, but has a 2.8 @ 3.14, and 4X256 of Kingston Value Ram (dual channel as well). I don't check her temperature... but there hasn't been any problem. She does a lot of photoshop work, and will have a million windows open at a time.

pinman

29th March 2005, 13:22

Thanks for the feedback Billy. Those 60C + temps are under full load doing folding and playing FarCry. My chipset temp never goes over 40C.

It must be that Prescott Core Celeron D that draws all that power though the MB that heats it up.

Thanks for checking.

Billy_Bat

2nd April 2005, 15:14

lol, that's why I don't monitor the temp on Sarah's machine... that Prescott is probably a flamethrower! But there hasn't been a problem, and a problem is just an excuse to upgrade!

MikeTimbers

If you're not going to monitor a Preshott at least run Throttlewatch (http://overclockers.com/tips00715/)

pinman

If you're not going to monitor a Preshott at least run Throttlewatch (http://overclockers.com/tips00715/)

My bios had an option to allow or disable processor throttling. I have it turned off. I'm guessing most have that option?

Billy_Bat

6th April 2005, 23:30

I turned it on with mine, but I never could get it hot enough to kick in. (I didn't try with the fan unplugged :eek: )

I do have it turned on with Sarah's Prescott, if it has ever throttled down, she hasn't complained. (probably because if she does it'll be an excuse to upgrade!)

Just a quick note to say that a newer version of SuperPi is out that calculates to 3 decimal places. Grab it from http://superpi.radeonx.com/

My new Centrino laptop @ 1.7GHz scores a healthy 48.450s for the 1M calculation.

My Celeron D 2.4 @ 3.6 Ghz gets 48.844 seconds on 1M test. A friggin processor at half my speed beats me by more than double. :confused:

Dothan core Pentium-M processors are arguably the best cpus that Intel make (and actually sell as opposed to those they announce but don't have).

Hopefully, the K8L cores will get the AMD side to close to those performance levels. The competition seems to finally be paying off..

A few people (specifically Mike) like to see SuperPi results....the 1M test especially. Post your results from your madly overclocked boxen! SuperPi can be downloaded from here. (ftp://pi.super-computing.org/windows/super_pi.zip)

Specs:
Asus SK8V
FX-51 @ 2.5GHz (200x12.5)
2x 512Mb Corsair XMS3200R

Results: I get a 34 secs time. (http://homepage.ntlworld.com/phil.harling/images/fx51/fxsuperpi.gif)

Wow, this feels just like yesterday! The above beast is still going strong and until recently has been running 100% load, 24/7 with the d.net RC5 client. I have recently stopped participating with this machine as it uses a boat load of power for very little return (a PS3 is orders of magnitude faster and more economical). Anyway, the system is still running, albeit at stock speeds as a Geovision CCTV server/ DVR machine monitoring the external views of my home.

It's amazing just how far things have come in the last 3 years though. That FX-51 was the cream of CPU's at the time and I paid just over £600 for the pleasure :eek:

Well, I've just put together a new system for use in the living room as a media centre PC and is hooked up to my HD LCD TV. It cost roughly £600 in total if you exclude Vista and my Dinovo Edge keyboard lol. Anyway, I thought I'd give some specs and a Superpi time. It's not overclocked but is plenty fast and silent.

Shuttle SP35P2 Pro Barebones
C2D E6750 (2.66Ghz)
2Gb Geil Ultra PC6400
Passive cooled Geforce 8500GT
500Gb Seagate Barracude SATA2 300

So, out the box it runs a 19.2s 1M SuperPi calculation....15secs faster than a 3yo Proc and almost a full system for the same price!

Just how much power do we need lol?

MikeTimbers

17th January 2008, 15:30

You can't not overclock C2D chips. It would be a sin not to.

13 seconds for my new E8500. I am running it in the same setup as my last post in this thread but I just selected 10% OC from the BIOS so 3.48GHz - default vcore:

Shuttle SP35P2 Pro Barebones

Overclocking by numbers? Phil, Phil, Phil. And you an ex-doyen of ACHO. Pitiful.

:p

phil

9th December 2008, 15:38

:rofl:

I really like this dynamic overclocking option available on this shuttle. It only raises the fsb when there is a demand for it. On idle, it sits at 333x6 (2Ghz) but when I load the CPU, it raises the multiplier to 9.5 and raises the FSB by the amount you set (5, 7, 10, 15, 20, 25%). So, you have the best of both worlds....good power management at idle and more power when needed :norty:

You also have the option of overclocking conventionally by hard setting the fsb but I think I'm gonna play a little more and see just how far this dynamic overclocking can go. After all, +25% is a 416 fsb (3.9GHz)!
