I'm not sure how this will go down. CeX are selling used 1-core Intel Celerons and Pentium 4s for very little. I don't know much about PC building, but if your motherboard supports it, it would be a good backup. I wouldn't recommend these for daily use. Most are instore but a few you can order online with free delivery if you're quick. CeX are usually quite good about returns and they do test all of the things they're sold.

A few examples:
Celeron 1.8 GHz S478 - £1
Pentium 4 1.7 Ghz Socket 478 CPU - £2 (+online)
Pentium 4 1.8 Ghz Socket 478 CPU - £2.50 (+online)
Pentium 4 2.4 Ghz Prescott 533FSB S478 - £5 (+online)
Celeron D325J 2.53GHz LGA775 - £6
Celeron D336 2.8GHz LGA775 - £8 (+online)

There are lots more. Once you get up to £18, there are dual core ones too Dual Core such as the E2140 (1.61Ghz) LGA775. If you want AMDs, they start at £8:

I use this website for comparing them. It's not very accurate I hear, but it has lots of benchmarked processors. http://www.cpubenchmark.net/cpu_list.php

anything that'll be an upgrade from an AMD Athlon XP 2400+?

Anything on the AMD list is better according to the benchmark site.
#3
lol didn't see the AMD list :) lol cheers, will have a look now (tries to think what motherboard he fitted....)
#4
Are you sure these are not faulty processors. Do you get any warranty.
#5
Be careful on pricing, some of the on-line availability AM2 prices look a little high in comparison to other sites.
#6
best processor i can get for my motherboard is an amd athlon xp3200+.........but i cant find one anywhere lol

Well it's only a few quid, but I assume CeX do not test them when they are brought in. So for all we know it could be someone pulling them out of dud units and selling them for profit.


I'm guessing that they would test them. Its wouldn't be a good business plan to buy parts from customers that did not work and then try and sell them as working......:whistling:

Is it really worth upgrading a PC that old? I've had a PC with an Athlon XP3000+ for the past 7 or so years and have recently replaced it with a C2D laptop. The difference in performance is incredible.
You WON'T see much of an increase in performance between an XP2400+ and a XP3200+

All CEX stuff comes with a 12 month warranty as far as I am aware, and yes they usually test everything before buying it.
#10
sod it, i'll just wait till i can get a new pc

i only use it for converted videos & playing "killing floor" anyway lol.
#11
i've got a dell dimension 8100 with a 1.3ghz p4 processor ( i think) whats the max processor i could upgrade to?

I've been thinking about adding some extra juice to my Dads old computer for a while, already had a memory upgrade, but he has a 2.4ghz Celeron, 478 socket so I was looking to see if the P4's would make that much of a difference. Highest P4 Cex seem to have is 2.4-2.6ghz.

So can upgrading from Celeron 2.4ghz to Pentium 4 2.6ghz really make that much difference?

£6 isn't so bad, probably around that much from Ebay with postage ontop.

You'll get a bigger cache and maybe a higher FSB with a P4 over a Celeron but to be honest the speed difference is going to be negligable

On paper yes, the Northwood based Celerons were the worst they ever made because the design at the time was highly reliant on cache hence taking most of that way crippled the performance of the processor. However in reality I doubt it would make any noticeable difference if the PC only sees light use unless he's doing a lot of video encoding or similarly cpu intenseive tasks.

Will bear this deal in mind next time I'm working on a dead 478 system as a few quid to revive an old system would be acceptable.

Johnmcl7 & GAVtheRAV, thanks for the answers, and yeah it's incredibly light use, the internet is mainly his day to day activity, few light-weight programs, the speed of the system to him isn't bad at all but if I have to help with anything I can't stand it.

If you can get it cheap then I'd definitely recommend u do the upgrade mate....I upgraded my gf's 2.4ghz celeron to a 2.66 p4 about a year ago and the difference was absolutely huge! Prior to that, the pc was just so damn slow! Of course, the p4 still isn't that fast if ur used to a c2d but it makes it much more useable.

(I should note that I also upgraded the ram from 256mb to 760mb so I'm not sure which one had a greater effect of increasing the speed but the two combined was a winner!)

If the PC was running XP then i suspect the ram made the [majority of] difference there. XP isn't great with less than 512MB

ive just chaged a celeron 3ghz for a 2.8 P4
the P4 kicks the celerons ass!!!
if your board can run it i would go for a 3.0 ghz P4 for all they cost.
though i just clocked the 2.8 up to 3.06 with no worries

I agree - ditch the Celeron for a P4 - you'll see a big difference - Celerons are sh**

Woulden't touch these lot with a barg pole haveing a right do with them at the mo got a

As others have said check how much RAM the system has as if it’s too little upgrading it will make a dramatic difference whereas upgrading to a P4 will only normally be noticeable when dong something intensive like gaming or media encoding. If he doesn’t do anything intensive I wouldn’t spend the time and money upgrading the CPU.

I bought one new when they first came out...awesome cpu still going strong in my shuttle pc.

Exactly. But to be honest, your board probably uses DDR1 memory, which is very expensive compare to the (semi-)current DDR2 memory. You can get a new board, a dual core CPU and 4GB of RAM for just over 100 pounds, and that is probably the most cost effective upgrade. You could spend that on 2 GB of DDR1 RAM alone - and the system would still be a lot slower.

i was surprised how expensive DDR1 is
thought i would get 2 gig for under £20 easy like when i last bought DDR 1
how wrong was i:oops:
#27
No surprise really, old ram is more expensive because it's not in demand as it was before, and it might well have gone to limited production or not even manufactured anymore.

But for the sort of person that is skint or relatively happy with their current PC adding 512MB of DDR PC3200 will cost around £7 or less from eBay. That’s a lot less money and a lot less time consuming than upgrading major components and most people don’t have the skill to swap out a mobo which might require reinstalling Windows also. For that sort of system 2GB is usually overkill anyway and it doesn’t cost £100 but more like £30 to £35 or less if you’re patient.
