Spoilt for choice

[furiousV]

i would like to overclock my Pentium 4 2.8E Prescott to something like 3.2 or so (and get really serious later on, Tesco have called back today asking me to stay on, since i was a temp over christmas, so i am going to have some income )
looking at www.overclockers.co.uk , there are so many HSFs to look at, but really do not know where to start. are they all actually suitable for overclocking, some say 'Up to 3.6GHz' and so on.
the prescott are rather hot, idle at 44-47oC from boot
49oC idle after being used
55-56oC during intensive use.

currently im using the standard supplied HSF, is that actually any good for overclocking to other factory standard speeds? (im not implying that the 3.4GHz is a overclocked 2.8, but wouldnt they both be supplied with the same heatsink?)

and why is my FSB 200MHz when the box says 800MHz?

any help will be greatly appreciated

 

[Eg.]

xp-120, that prescott will cook if ur not careful, wc is the norm fo rit

i hear of people achieving good clock speeds with the standard cooler, but not sure if they meant northwood or prescott.

if i were to save up for water cooling (most likely my feb paycheque will be nice and big enough), would o/cing with stock fan be advised at all? just to 3.0 or 3.2?

im asuming you meant watercooling = wc

looking at the Thermalright XP-120, im wonderin if il have enough room between the CPU and the PSU. there is only a 2cm gap between the edge of hte HSF and the start of the powersupply.

Your FSB really is 800mhz, its just that the proper FSB is 200mhz which is quad pumped to 800.
Just like DDR ram is actually 200mhz but DDR performs 2 clocks cycles per second (or something like that) giving 400mhz.

Next your cooling.
Most aftermarket heatsinks are usually larger in width than the retail heatsinks, therefore you have to take into considerations like your PSU being too close or capacitors in the way.

Best to check in OCuk whether it specifies what boards are compatible with the heatsinks ard which are not.

PC world (although usually shite!) are offering a watercooling setup at the moment for about £141, You may be able to pick up the same model, cheaper elsewhere, But this WC setup uses InertX PF5080, this liquid is none-electrically conductive, and if it leaks, it just evaporates instead of frying your hardware.
The model is the...... Coolermaster Aquagate .. see the link here..

Apparently it can keep the Pentium 4's about 10 -15*c cooler when its running at full speed.

The only problem is that it is an all enclosed WC system, so you can't add a VGA or Northbridge sink later if you wanted too.

But it'll give you an idea what you can get.

just when i thought i understood all about megahertz and all that other fancy stuff, more stuff to learn crops up. the cache latencys, well nm. thanks uve answered a question that was buggin me

i found the same watercooler (what should the max temp be of p4?)
http://www.overclockers.co.uk/acatalog/copy_of_copy_of_Others.html
ocuk give it for £135.07 inc VAT, PCWorld for £141.36

a PCGamer mag featured that watercooler in their overclockers guide. u know that big page with "build a pc for under £500" and all. il think about getting it when i get the tax office to give me back my £300 tax that i SHOULD NOT BE PAYING!!!! argh stupid inland revinue. (and im just too lazy to get that P45 or whatever it is) :dork:
oh, another stupid question :dork: 'why' add extra cooling to your northbridge? (i found that the Arctic Cooler rev 3, the clip that mounts the GPU gets in the way of the northbridge heatsink)
its not that you o/c your northbridge is it? ok il admit, i know nothing ;( what exactly does the northbridge do?

Asus P4P800E Deluxe (i865PE) Socket 478

some hardware explaining links would be really appreciated, i would like to understand about this hardware stuff, cuz ive got more questions coming up

Just like DDR ram is actually 200mhz but DDR performs 2 clocks cycles per second (or something like that) giving 400mhz.

I made an error, I meant that DDR ram performs 2 clock cycles per NANO second, Not per second..Doh!

Anyways...The northbridge (usually the small 2cm square heatsink on your board, with or without a fan) Performs the function of a memory controller.
Basically AMD have done away with this in the AMD 64's, Cos now the memory controller is inbuilt into the AMD 64 cpu.
So in your board and the old athlon XP boards..Data is passed from the cpu through the northbridge and into the system ram, Since this northbridge gets hot and is connected to the memory FSB its useful to be able to keep it as cool as possible, The cooler it is, the more increased memory FSB you can get while keeping everything more stable, Speed is nothing without stability.

Another cooler you could try is the Zalman one, That big, blue one that acts as a huge heatsink (its about 2 foot high).
I'm sure I've seen a PC with this installed using a cpu,vga and northbridge sinks.
Its roughly the same price, Although I'm not sure whether InertX PF5080 is able to be used in it, Since this stuff costs about £50 per KG then it could prove costly.

If you want to really learn about watercooling, I suggest you register and post in the forums at www.futuremark.com
Some of these guys here use not only water cooling but Co2 and Liquid Nitrogen, Thats about extreme as you can possibly get.
