overclocking P4 3EGhz

Toggle sidebar Toggle sidebar
:) no I'm asking the FSB
is it possible to reach 1000+ my current FSB is 800Mhz?
I'm goin to upgrade my ram soon so the DDR500 might help me in OC? right?
I'm planning to buy KINGMAX HARD-CORE series DDR500 cheaper than corsair and kingston..
 
lol this is going round in circles

(repeat what everyones saying in a diffrent way) a P4's FSB runs at (eg for FSB800) 200mhz but its effectivly 800mhz (equal to) as its QDR or Quad Data Rate (4x) so its 200x4=800mhz FSB and to get FSB1000 you have to overclock the FSB to 250 to get 250x4=1000mhz FSB and because P4's are multiplier locked (and yours at 15) when you raise the FSB from 200 to 250mhz that changes the original 15x200=3000 to 15x250=3750.

It seems like your a newbie at this, i suggest to google "overclock prescott" and see what everyone else has to say bout prescotts but here are the basics:

As for overclocking, dont go straight from 200mhz FSB to 250mhz FSB, do it in ~5mhz increasements.

As for Ram and overclocking, if you run the ram Async with a diffrent ratio (depending on what ur bios has to offer) you could run it at the '333' setting to when you get to FSB1000(250) your ram will be back to the stock 400mhz, but performance wouldnt be as quick as if you had ram in sync.

Prescotts are hot.
You will need excelent cooling to use a prescott (even with stock speeds).
Prescotts throttle and performance may be worse after overclocking.
 
no i'm not planning to buy new PC right now, because i'm goin to buy notebook f0r school, but maybe next year (2007), i will use AMD fo my new PC :)
 
my Prescott is overclocked, and its running at 21C/69F. Yes, right now. I'm using a 3.0Ghz processor overclocked to 3.22Ghz. When overclocked to 3.48Ghz, its only mildly higher. Like, 23C. :roll: I've heard so much crap about Prescotts running hot, I don't know where it all comes from. Most ppl who claim they run hot haven't experienced it themselves, or have a crappy set up in their system, like being dusty.

Click to expand...

soooo your prescott runs at 23 C overclocked... lol
looks weird to me because a prescott may start at 43 C doing nothing if it's perfect... even a watercooled prescott is over 30 C ( human body is 40 C ) so if you touch your heatsink it should be cold while your cpu runs... if you use stock air cooling, may i suggest that the sensor might be wrong. all prescotts i've seen were aroud 50 C and running up to 75 C with stock cooling. even a via c3 chip ( passive cooling ) with a real heatsink on won't go below 25 C
 
well, assuming the sensor is right,

to get 37 C could be a socket sensor. or chipset sensor ( mobo temp )
( with a fan blowing directly on it )

anyway, what program or tool give you that temp 23 C
( if it's an lcd screen in front of your case, the sensor is still on the intake )
 
in my thread about it I state the reason why, I have too slow of RAM, and clocking back makes the RAM underclock... system works great at 3.48Ghz. I could leave this thing on 3.37Ghz (overclocking my current RAM to DDR454, and its a DDR400 stick) currently, at my 3.22Ghz overclock, I have my RAM overclocked to DDR430. Seriously, this thing is pretty cool, maybe the sensor is out, but I still think its running pretty cool. Ambient is about 20C. Processor is running at about 21C now.
 
It all depends Wusy.
My 3.0E does 3.75gig on stock voltage with memory set to 320 or 5/4 ratio. max temp so far is 58c running Stability test. A couple degrees higher than prime or Folding@home.
Of course I'm using a Thermaltake P4 Spark 5 copper heatsink(2 years old) with the fan turned down to 11/16 . Much too noisy at regular speeds.
Never tried the stock cooler. Still in the box.
 
recommend me a good motherboard.. even though it'll be a lot of work to switch motherboards, I think it would be worth it if I could overclock more.

Two things I forgot to mention the other night, and that is its a LGA 775 socket CPU, and I get those low temp readings cuz I leave the cover off, I never put it on. The whole system runs a lot cooler with the side cover off. Under stress, with the cover on, it reads more like 42C. :)
 
I'm a big fan of Abit, Asus, and Gigabyte: in that order. If you're going Pentium, I HIGHLY recommend targeting an intel chipset rather than a particualar Mobo Mfr. Find your ideal chipset (Intel usually releases 2 at a time: a mainstream and ahigh-end). The latest chipset is the 955X.

I've gotten both good and bad mobos from the above Mfrs, so find your chipset and then research the difference between the different Mfr's boards: features, and common problems. I usually browse the Mfr message boards as well.

Abit and Asus usually have better overall OC solutions, while Gigabyte seems to be more creative value-adds, such as Dual Bios' and 'Wind Tunnels'. Abit's been pretty good about quit and creative cooling solutions, too. Asus has thier BIOS AI or whatever, which seems to be more bark than bite, usually.

Anyway, pick a chipset (I recommend Intel's 955X, or wait for the 975X for Crossfire), and then compare the different implementations. Stay away from SIS chipsets. VIA is hit-or-miss, but you get what you pay for. If you want nVidia SLI, get nVidia's new chipset for intel procs.
 
My Prescott doesn't run that cool but it does run 30 degrees and under load it goes up to 39 degrees. I ran prime95 and it only went up to 43 degrees and that's running it clocked @ 3.27mhz with a zalman air cooler. My AMD 64 has a similar setup and it runs about the same temps maybe about a degree or two cooler if that. No big deal to me.
 
I'd go with Abit if I found one with a good Intel chipset for good $$ thanks for the tips :) Maybe even Asus, but I'm looking for one that will handle a good overclock.
 
I’d like to point out that if you have proper airflow it’s cooler to leave the cover on then keep it off. Since you create a wind tunnel that ducts air directly over all the critical areas.

I think some of you are getting dud readings on you temperatures. My 3.0E idled at around 50c with a zalman cooler. Now I went liquid and it idles at 48c ocd to 3.75 250 fsb… the biggest difference is while the cpu could go up to nearly 70c under load with the zalman, now it idles at 58c under load with liquid. I can break the 4ghz barrier completely stable, but the returns are diminishing.

Prescotts (well p4’s in general) can get fairly insane over clocks. Provided you have enough cooling 300 fsb is fairly easy.

For intel overclocking I'd always go with abit. Their boards are solid OC platforms.
 
my celeron D 2.4ghz (socket478) hits 3ghz on stock and no further, but the same chip with better cooling hit 5ghz on the net somewhere so i want to try for that some day.

oh yeah - wierdly runs cool at like 58 under load on my ASUS P4P800S

As for my main - P4 2.6c @ ~3ghz stock cooling - what would a better cooler do for me?

i agree on the case on theory - case off runs cool for a while till the hot air gets recycled and heats up more where as a case with decent front intake and rear outtake will run cooler.
