Pentium 4 benchmarking
 

Just got myself the ASUS P4C800-E mainboard for s478 benchmarking, available CPU's:
P4 1.5GHz/256/400/1.75V
P4 1.4GHz/512/400/1.3V

DRAM of choice: Corsair XMS 3200LL (BH-5)

Test setup:

1ste tests with P4 1400MHz:



2000MHz CPU-Z verified: http://valid.x86-secret.com/show_oc.php?id=442017


Problems I'm running into:

- Multiplier is stuck to 12, while 14 is the default value. 12 is battery saving multiplier.
- DRAM divider malfunctioning, can't set anything else then 3:4 at this moment which makes me run into maximum DRAM frequency pretty fast.
- Board freezes randomly after VGA artifacts

More to come the following days...

time to mount the single stage, mobo should be good for 250+Mhz FSB, reaching up and over 300Mhz if you can handle it

wish the memory divider would co-op with me for that :s

Bios flash?

TCCD ram is maybe an option , slower timings but higher mhz.

I'm not 100% sure but I think there is something wrong with the board as I'm getting VGA erros all the time. Tested 2 S3 PCI videocards in every PCI slot as we speak.

For TCCD ram, you need to flash the bios :

if u need a other board : contact maximus on 9lives ;)
p4c800 he had i think still fully modded from back with dothan :P

Got this board via him ;)

You interested in my P4C 3.0 now that my AI7is dead ?

Not really, seems like the old P4's are working samples :)

3000MHz watercooled:

100% OC in the bag, nicely done! :D

My previous pair of DDR ram was dying, could run memtest. I have the system up again with a new pair of BH-5's, memtest stable and yet I'm still running into artifacts. I can hardly open CPU-Z and superpi at the same time. Taking screenhots is out of the question at this moment :no:

Near 300MHz at this moment:



Notice the places where I had to switch memory devider.

Looking good, G.

Could you send me the XLS file with all the data? I'd like to do some math on it myself :D

(btw, please fix the printscreen issue you have; people seem to be bothered that your verification on hwbot are photos)

are you using the "SuperPi" OS?

Can't help it, every time I load the graphics card the system crashes :(

But photo's are okay I presume, you can read everything and they are much harder to manipulate for photoshoppers.

No, Windows XP SP2, with some services turned off here and there. I know, wprime scores suck :(


EDIT: superpi OS?

yes there is a superPi OS out there; tweaked Windows OS; might give you a few better scores. will give it to you Tuesday

regarding SS, mspaint doesn't work on your XP SP2 install?

Yes I got paint, that is not the issue. The system freezes when I press print screen 90% of the time. It often freezes when I open paint, open task scheduler, ... You see, even taking a photo is a hell of a job, when I try to grab and drag a window, system freezes. For one stupid superpi score it happened that I had to reboot 10 times before I could have every application nicely line-up in order to be hwbot valid. For every benchmark I have cpu-z, memset, clockgen running in the background, times are still okay since I could easily beat the competition cpc when I was testing the 1.5GHz willamette. Yes, better is possible, wprime and superpi 32m, but it takes so long that I'm not really interested to tweak it down just because of the printscreen issue.

The setup can run 2h wprime stable, it can run through memtest at high frequency's no problem, but just don't do anything complex like dragging windows :)

At optimal settings the OS uses not more then 30MB memory space though, don't think I'll gain much be using other OS. Or is there more then meets the eye?

much more; if Massman is to be believed, some copy wazaa trickery can lower your SUperPi times

ah yes, an OCX member has made a small utility which simulates copy waza. I'm not using it at the moment, not needed in order to take first spots in superpi :) But... it wouldn't heard to have a copy of such well tweaked OS, safes me the time I would otherwise spend on shutting down everything which is not needed :)

It's not the amount of idle memory usage which is the key for having a good benchmarking os, it's the efficiency of the memory and resources usage that's important. Copy-waza basicly prepares the system for big calculations, which has quite a decent influence on the system's performance. For instance, iirc, the AXP setup would apparenlty have been 0.2s faster in 1M if we'd done a copy-waza.

server 2003 is best for P4 G ;)

Faster then Superpi OS? :D

What kind of calculations? Efficiency?
You see, this board can go quite high on FSB, but with multi 12 I aint going to get much higher in frequency's when using LN2, need to get the multi 14 working. 14x190=4060MHz, now that's something, CPU will probable stop clocking earlier though, 3,8GHz~3,9GHz at most. Its a step B, not same quality as Northwood step C. Would yield in roughly 180% oc, not that bad :)

EDIT: how exactly did you do the CPU microcode bios modification on your PT800 board?

I'm in doubt about the OS; it might even be so that win2k is faster on this old technology. For the Athlon XP, Win2k is apparently faster.

Yeah, I was going to check efficiency, but haven't come across anything interesting so far. It might be cool to find out in how far memory timings and dividers play a role, but that's only interesting for data analysis, not really for breaking records.

Is the multiplier of that cpu unlocked? Why doesn't 14x work?

I changed the CPU Microcode using bios editing programs, as far as I can remember. Firstly, I extracted the microcode out of the bios of a recent motherboard, then added the microcode to the new bios. It was a fairly simple program to use: completely GUI. I'll search for the program and link you :)

No idea why it doesn't work, 14 is full speed multiplier, 12x is speedstep multiplier. Probable same reason as with the E8600 on PT800, not completely supported.

What bios are you using?

Latest, F23: P4C800-E Deluxe BIOS 1023
This BIOS support mobile CPU adapter card CT-479. Please do read the description before updating BIOS
Do not use old version Afudos.exe to flash BIOS.Must use new Afudos(2.07) or later revision to flash BIOS.
Using ASUSLiveUpdate to flash BIOS, you need to upgrade ASUSLiveupdate to v5.22.02 or later before flash BIOS.
This BIOS is for motherboards purchased in a retail ASUS package. If your motherboard is part of Compaq X07 Gaming PC or Compaq X09 Gaming PC systems, you should obtain BIOS updates from HP, as using this BIOS may have adverse effects, such as rendering your system unusable.
Support CPU multiplier item when using Dothan 533 with CT-479

F24 is beta BIOS, don't see why that BIOS would suddenly support the Pentium 4 mobile since these CPU's were launched way before BIOS F24 (y: 2005)

Can you fix something for me PJ? I have all the mandatory apps and all...

email NeoForce with

as comment:)

Thanks! I'll link him to this thread ;)

U can also use this tiny program http://www.xtremesystems.org/forums/...d.php?t=203196

nice find!

I tried snagit, no better :(

Here we go again, NeoForce certainly didn't pay tOo much attention last time...

what where?
you really have to find a solution to the system freezing during screen grab as this will stop any issues. your scores can be blocked if they are deemed suspicious :-/

Ever since last time I have not posted photo-screenschots, along the blocking work one of my submissions must have slipped through his net. Well, I don't blame him, probable the other guy in the category who wants his silver cups in gold. He got his cpu stock ffs, guys really have no shame from time to time.

can you post a linkie to the score in question please?
