yes i am bro. 24/7 download machine! mostly dl HD files

HD files? then can those files be played on d same pc? 

thanks.
any idea what the suitable graphic card i can use for this Intel D865GBF?
its AGP.

720p no problem smooth as butter. 1080 then 

Very hard to find one now... so sad, lat time I had one...kanchong, kanchong go & sell ony 

720p can run fine on P4m 2.0Ghz with 512MB ram with normal Radeon 7500 GPU that does not have any HD hardware acceleration (even if you have nvidia 7600GT AGP also no hardware HD acceleration). If lag, i think is your pc resources issues, such as background programs, etc that hogs certain % of your CPU.

using klite codec pack. if using coreavc, results are better 

Radeon 3850 bro. Had one before, then sold it...

Now I have a 6800GS only. Also have a 4600Ti, Geforce 3 Ti200 and Radeon 8500.  About a dozen other non-interesting cards also, like FX5200, 6200, etc.

Also wanna update, changed my cooler to a CM N620, with custom bracket, and stable at 3.95Ghz so far.  Going for 4 ghz, maybe more if I can 

Updated: 4ghz

Thanks bro. FSB at 1066mhz, ram at 177mhz CL2.5 - cause my rams are just generic stuff.  Temps even with the new cooler are low 70s during intelburn test. My test room is not air con'ed- ambient temps are high- so that's a big minus point.  The whole case gets blazing hot until even the panels feel like the side of an oven.  You can actually start sweating sitting around this system.  Stability is of course best early in the morning 

Stability tests completed at 4ghz- intel burn test 10 loops maximum stress, superpi 32m, unigine cathedral, prime 95 2 hrs and 1/2 hr of NFS:MW.  No 24 hr prime test- I just don't believe in 24 hr priming anymore, the stress it places on system components is lethal and I prefer more real world tests. High power draw of the prescotts at 4ghz will burn out mosfets eventually.

Now that I've hit 4ghz, I'm gonna lower it to something "sane" for 24/7 use - maybe 3.6ghz .  I kinda like my retro P4 so I want it to last just a bit longer. 

Long time no drop by this thread. Seems is till very active.

@SGT76
Maybe you can include all the parameter such as ram timing, voltage etc. Just my suggestions.
Running at 4GHz is superb, but too much of heat generated is another issue. A 3.6GHz would be sweet enough to run daily works.
@raymond
Bro, perhaps is time for you to go further than 3.6GHz.

It has been a while since a P4 user uploaded his 4Ghz clocks

Running at 4ghz is scary- the system feels like it's on a thin edge. The air exhausted out the back fan and psu is like a building exhaust vent.  Case side panels hot. Northbridge heatsink WILL burn fingers real fast, vcore fluctuates due to droop. 

Parameters are:
ram timings: 2.5-3-3-7 @ 177mhz dual channel
voltage set in bios to 1.385v, but due to vdroop it fluctuates wildly.  Setting it higher than this pushes temps way too high.
pci/agp/sata all locked at 33/66/100
super patch and all auto enhancements off

hardware is:
Processor: Prescott 3.0 E0 stepping
Motherboard: DFI 865PE-AL
Ram: 1 stick Kingmax 512mb DDR400 and 1 stick Kingston 512mb DDR333  (either it shows how ghetto my rig is or that you don't need high performance rams)  <-- anyway I'm looking for a set of better rams
CPU cooler: Coolermaster Hyper N620, with modified Deepcool s478 mounting, 2 x12CM fans
Thermal past: Zalman
Graphics: Nvidia 6800GS, Palit oc'ed version, further pushed to 470/1300--> faster than a 6800 Ultra
Hard disk: 2 x 40gb (1 maxtor, 1 Hitachi)
Optical drive: Sony CD/ DVD combo
Floppy: Sony 1.44"
Sound card: SB Live ! CT4830 with EMU chip (on-board sound doesn't like oc- becomes flaky)
Case: Coolermaster Elite, forgot which model- 3 x 12cm CM fans
PSU: Tagan 480w
Others: CM Musketeer with bling bling meter

Future plans: get some better rams - Kingston Hyper-X or similar, more modern video card- Radeon 2600, 4650 or 3850, add more fans - maybe 2 in the rear in sequence to extract hot air faster, heatsinks on mosfets, southbridge, ram cooler.

3.6ghz on Northwood is very impressive.  Before this I was using 2.8b, max stable oc only 3.36ghz. Clock-4-clock, Northie is 10% faster than presscott I think, so your 3.6ghz should be about a 4ghz pressie.
Ya, ya 3:2... my matematik very phail one  thanks!

C Northie is the best P4 bro. Northwood only 21 stage pipeline, prescott is 30 stage.  Make many many extra rounds in the silicon, then only the superpi come out.

Very inspired lah joining this thread.  I think today I go back I'm gonna tweak my system some more and try to get that 4ghz 24/7 stable.

Prescott has a longer pipeline compared to the Northwoods
So clock per clock at stock, the Northwood is able to beat the Prescott

But due to smaller dye for the Prescott, it can scale higher than Northwood in terms of overclocking to compensate on the longer pipelines

Clock to clock it definitely beats the Prescott in stock form, that is a fact after all but not when the Prescott is overclocked
With the help of a larger 1MB cache couple up with high overclocking ability (0.09 micron), the longer 31 stages of pipelines is easily being compensated

About significance....for a P4, a 400Mhz bump in clockspeed, the gain is so negligible that one can say it is close to non-existence (which for me is true, just nice to see high clockspeeds )

It does help in speed/performance in applications, just that it is negligible even though with HT on. However in Windows, it is close to non-existence. If it is snappy, it will be snappy.

the Gflops in intelburntest for the P4 is 4Gflops from the screenshot. My X3220 oc'ed to 3.3Ghz is 44Gflops...

Thanks bro. Learned a lot from Lowyat from reading all the posts, now I'm just giving back by sharing some info.

Getting this to a stable 4ghz for practical 24/7 usage was the most challenging project I've ever undertaken- had to add heatsinks on all the mosfets, modify the custom mount a bit more, tweak the volts, remove unneccesary hardware (4ghz prescott is a power hog- Tagan 480w is almost not enough for it!!!), bios tweaks, carefully route all cables and wires and ensure optimum airflow.

Running 4ghz all the way 24/7, no cranking down. I was surprised too at the power usage.  This PSU has served me well in the past on my old Athlon 7750BE system (overclocked 3.16Ghz) with 8800GT, 3 hard disks, 1 DVD burner + 2 120cm fans. 

But it's marginal for this system.  I have stripped this rig down to the basics- 1 hd, 1 cd/ dvd drive, 3 120cm fans, 6800GS card, SB Live! sound card.

my system is pentium4 3.0E Ghz, currently my best o/c is 3.6Ghz only (15x240Mhz) on AI7 mobo with 2 GB Gskill PC4000.want to go to 4Ghz, i think maybe it is my psu limiting me to go further.my psu is rated true power at 450W, must be my GC taking drawing alot of power, it's a HD4650.What you guys think?

Not only the mofsets being hot
The Abit mobos are plagued by the infamous Vcore flunctuation as well

the Gflops in intelburntest for the P4 is 4Gflops from the screenshot. My X3220 oc'ed to 3.3Ghz is 44Gflops...

yeah i know that. last time my pwm temp can shoot up to 90 deg cels bcoz no proper exhaust fans but now my pwm temp reads around 53~58 lor.i did slap some mosfet heatsink onto it and improve the exhaust fans by using 80mm panaflo fans.as for my proc temp is around 52-56deg cels.so i dun think it is my proc temp either.im using CM hyper6 for the HSF.i did noticed the vcore fluctuate a lot. (between 1.36~1.39).

you also using ai7 mobo? maybe it is ur mosfet overheating. once that happens the efficiency of the voltage supplied will drop seriously.

i got 5 F3's in my rig, no problem at all for reliability and the temp is lower than WD Green.
