Re: Overclock or buy new CPU?

Any suggestion for the best buy CPU that can rival low end PIII?

I just finished upgrading my c300a (450mhz) to a CeleronII 566 that runs 850mhz @ 1.64volts. Performance is comparable to an Athlon 750 or PIII-733. Great upgrade for a BX motherboard. The total cost for this upgrade was $136.

I have a Celeron 266. Would it be a good idea to overclock it or get a new CPU instead to play F1 2000 or GP3

New CPU and MoBo. --

The Celeron chips didn't add an L2 cache until the 300a model. Even oc'd, the 266 won't be very fast for today's standards. Depending on your motherboard, probably a new cpu would be the way to go. I don't know how much you have to spend, but if you're looking for a cheap way out, I have a 300a that oc's to 464 mhz, very stable at 1.95 volts (less than default) that I'm willing to sell. It's slot1 and comes with the Global Win dual fan/heatsink. The Global Win unit is worth about $22, so I'd guess the whole unit is worth about $45. It should be able to work with your motherboard if you can set it to 100 mhz. Otherwise, there are lot's of good deals on faster chips that oc very well. -- Slot Tweaks & Reviews www.slottweak.com "GUCCIPHILE" <[email hidden]> wrote in message news:[email hidden]... > I have a Celeron 266.

i run a celeron 266 at 448 mhz, fine for GPL and most stuff thats out there currently, but it is showing its age, hopefully at xmas time I'll be upgrading Martyn_D GUCCIPHILE wrote: > I have a Celeron 266. Would it be a good idea to overclock it or get a new CPU > instead to play F1 2000 or GP3

Celeron 533a (make sure its the 533a - thats the FC-PGA, NOT the PPGA Celeron 533) or 566 should both o/c fine, just stick a decent fan/heatsink on it (somthing like a thermaltake golden orb, or an alpha cooler if you want to really go for it). Only half the cache of a PIII, so wont be as quick as an equivalent speed PIII (depending on what your running) but a lot cheaper! I recently bought a 566 and have it running at 850, it will even run at 950 but is a bit unstable at that speed and probably needs a higher voltage.

That depends on your motherboard, memory and how much you want to spend; and what you consider a low end PIII. I also have a C366 that I'm oc'ing to 600Mhz at 1.95 volts. I wasn't planning on parting with it, but who knows. You may find some good deals on these chips that will oc at least to 550Mhz. Your C266 may oc to over 400, but that's rare in a .35 micron chip, heat could be a problem depending on your case, and you'll still have no L2 cache so that will hurt your speed, etc. For my computer now, I'm running a C566 at 920Mhz. It's perfectly stable at that speed, I've had it past 950 but it did crash on extremely hot days after a few hours. One thing to consider about Celerons vs PIIIs is that at the same clock rate a PIII may show *slightly* higher general test scores, but in games the Celeron may be 1 or 2 fps faster. I've tested a few of them and the only thing I can figure is that the smaller cache on the Celerons is an advantage in many games. Think of the cache as a basket. It's faster to find what you're looking for in a smaller basket than in a larger one. Current games don't seem to be overloading the cache, so it works. A lot of info is now processed on the video card. Probably new games coming out will take advantage of the special instruction sets in the PIIIs, so that will make a difference, but it's hard to tell which games will and which ones won't. If you're also dealing with large graphics file processing (pictures) or running a CAD program, then the PIII will probably be better for you. What we're trying to do here is give you advice without know how much you are willing to spend and what your current system is. I'm willing to bet that you're running PC66 memory, so you'll probably need new memory and a motherboard. -- Slot www.slottweak.com Tweaks & Reviews "GUCCIPHILE" <[email hidden]> wrote in message news:[email hidden]... > Any suggestion for the best buy CPU that can rival low end PIII?

Hi to all, I'm a bit of a newbie around over clocking ! I have a PIII 450 and want to know what I can over clock this to and what do I have to do ? Thanks in advance for any advice, -- Martin [email hidden] __ []_.-' (Q_,._ (o)_[F1}____(o)Z>

Go to my webpage (url below) and check out the overclocking section.... 8-) *Peter* - http://www.cix.co.uk/~peterpc/home.html

Well, on Intel chips (as well as the new AMD's) the CPU's multiplier is locked, so to overclock you instead raise the Front Side Bus speed. Likely your FSB is set at 100MHz, and you have PC100 memory, and thus the CPU multiplier is 4.5. If your system's motherboard supports adjustment of the FSB, either in the BIOS or through jumpers onboard, you can raise the FSB. Ex., Set the FSB to 112MHz. Now your system speed is 4.5x112. Depending on the quality of your memory, you may be able to increase the FSB as high as 124 or 133. Anything higher and you will need PC133 memory. Also, adjusting the CAS latency in the BIOS settings can get a little more out of your memory, ie. if it fails at FSB of 133MHz at CAS 2, try CAS 3. Finally, stubborn CPU's which don't overclock (assuming you don't have a problem with your memory), can usually be persuaded by slight increases to the CPU core voltage, say by 0.05-0.20V (try this in increments). Like all things, there are some downsides to this. First, your CPU will generate more heat from higher bus speed and/or core voltage. You need to make sure to provide it with adequate cooling. Second, when you raise the FSB, you are also raising the speeds of the PCI and AGP busses in your system. Most recent motherboards provide both 1/3 and 1/4 bus speed dividers, so you can adjust the divider to get your PCI bus speeds as close as possible to spec, which is 33MHz. This is important because some PCI devices and also hard drives (due to their controllers) do not "get along well" with overclocked PCI bus speeds. As for the AGP bus, your only settings available for that will be either 2/3 or 1/1. Obviously you will use the 2/3, but at FSB of 133 for example, you have the AGP at 89MHz, which is way above its spec of 66. A lot of video cards can't handle this. The Voodoo3's and a few others, can however deal with it. Finally, all this overclocking of components, busses, etc., generates heat. You definitely want to make sure to have a roomy computer case with lots of proper (as in airflow direction) ventilation. Martin wrote:
