p4 2.4Ghz overclocking -> should i use the 533 FSB version or the 400 FSB ver? - Overclockers Forums
Hello everybody, I'm a graduating college student just entering the overclocking scene.
I have been around computers long enough the know the basics in both programming and hardware, but I wanted to see if I can learn more from the long time gurus here.
Any knowledge and help you can provide would be very appreciated
I recently acquired two Northwood 2.4Ghz cores (for very, very cheap), one running at 533 FSb and the other at 400 FSB.
Now I want to make use of these and stick one into my old HP Pavillion 752n:
original specs:
- 2.0Ghz Northwood P4 @ 400FSB
- MB: Trigem 129504 (brookdale-gl northbridge, 478 cpu socket, 2 DIMMs)
- MB is can run either 400 or 533 FSB
- MB only has 3 PCI ports
- PC2100 512MB (256 x 2) DDR SDRAM ->
I'm not sure if these can run dual channel or not
I also know that the motherboard BIOS is more than likely locked.
Which makes clockgen the only viable option.
Some other things that I also have at hand are:
- a Dynex 400w power supply
- 2 sticks of 512mb DDR rams (also pc2100)
- Visiontek Radeon HD2400Pro (PCI, 256mb memory)
- A Panasonic Bluray Reader (UJ-120)
- an extra 70mm case cooling fan
- an extra 40mm graphics card cooling fan
I think this is a good combination of ingredients for a possible HTPC in the making, and I want to overclock the cpu for a bit more power to run the Blurays, and perhaps to let me play some of the newer games at low-mid settings.
Would it be wiser for me to install the 2.4GHz 533FSB cpu to overclock, or the 2.4ghz 400fsb version?
Since the MB supports both 533 and 400, i was perhaps thinking of using the 400 fsb and overclocking the flow from 4 x 100Mhz to 4 x 133Mhz.
Would i need to match the overclocked CPU frequency to the Ram's frequency as well?
Any and all recommendations are welcome.
Thanks!

Seeing as you have both, you might as well try both.
If you don't want to do that, i'd use the 533 personally, either way you're likely to run into ram speed issues before you run out of CPU room.
The 533 should be slightly faster to begin with, and may have new(er) snazzy features like hyperthreading, though i really don't know as the only P4's i've messed with are a 775 prescott and a 478 800fsb northwood.

P4 Northwood cores only came with hyperthreading if they were the 800fsb models, so neither of those will have them.
To the OP, the 400fsb model might give you more overclocking headroom (I've never used clockgen so I'm not sure how much room that will give you though) than the 533 due to the lower fsb.
When I used to have a bunch of northwoods I tended to have the best luck at overclocking the 800fsb models, and then with the 533fsb models coming behind them.
About the RAM, I'd put in as much as it could hold regardless of overclocking (the 2x512MB sticks maybe), but I doubt you'll have much luck with running HD video or blue ray discs off of either chip.
When I built my first dedicated HTPC I tried a 3ghz 800fsb northwood and later a 3.0E prescott paired with a 3850AGP videocard.
It wasn't able to handle 720p video without massive stuttering even with GPU acceleration, so I'd doubt it'd work better for you in this case.
You should have no issues with standard quality video though.

Hmm I'm a bit unclear as to why the 533 would be more beneficial.
Some people have told me to use the 400 FSB model because it gives more headroom, but how does that work?
How is upping the frequency from 133 Mhz to say 166 any different from 100 to 133?
and no neither of my processsors have HT

Hearing about your old HTPC set up makes me lose a bit of hope.
Although... I do hear of some people successfully running HD content using a p4 3ghz and a video card similar to mine.
And assuming I oc the 400 FSB version to 533FSB would boost the speed to aprox 3.2ghz?
can this be done safely with clockgen?
Does anyone else have experience with a similar setup?

I'd run the 400FSB CPU at 533MHz and throw in that 1GB of RAM and call it a day.
You will not be able to play BluRays on it, but you might be able to play DVDs and that sort of thing.

No way in hell are you gonna be able to overclock the 400 fsb chip up to 533 with a bios locked board no matter what program you use.
The best you can expect to get it to is probably at the most is a 200 mgz overclock.
And that is if you are real freaking lucky.
If i were you i would throw the 533 chip in there and see what you can get out of it providing your pll is supported by any of the programs out there.
Good luck because you are going to need it.
