I have an:
AMD Duron 1.8 GHz
1 GB DDR-RAM
FSB is 133 MHz
s/Ts is 4,5 s
64 K L2-cache

What is the most important for the s/Ts?
Processor runs at 100% so it doesnet have to wait for the rest of the system.

Will more ram help? if the cache was bigger, would it count?
The new PC\'s have fsb with 1 GHz speed. Is that important or is it the processor?

How much beter is a P4 than a P3 and so on
Pls, someone who knows something about this, tell me.

Thank you :-)

The best thing is multi-core - while it doesn\'t make any single model run quicker, you can run two (or four, with Kentsfield, Clovertown or Quadfather) at the same time.

1GB is plenty of RAM for this project, whether you\'re running one or two.

Memory speed is very important, as is FSB speed (particularly with multi-core since there is more pressure on the memory).

First off, I\'m not an expert. That said, your machine has plenty of RAM; whether you can tweak the FSB depends on the quality of the installed RAM.

As far as I know, the P3 was architecturally superior to the P4 but couldn\'t be driven at P4 clock speeds. Pentium M is a derivitive of P3.

Both P3 and P4 are superceded in power/performance by AMD Athlon. Athlon is out-done by Intel\'s new Conroe, \"Core\" technology, in price/performance -- though AMD dropped prices a lot.

L1 & L2 cache are larger on faster CPUs. It isn\'t anything you can tweak on your Duron.

Do you want to replace that machine? If so, your budget is the only limitation. Much hardware discussion here:

If you want specific advice, that\'s a better place to ask.

If you want to overclock your machine, it could probably be done. However, stability becomes a bigger issue.

Greetings from coastal Washington state, the scenic US Pacific Northwest.

I have an:
AMD Duron 1.8 GHz
1 GB DDR-RAM
FSB is 133 MHz
s/Ts is 4,5 s
64 K L2-cache

What is the most important for the s/Ts?

Processor speed, processor type and memory bandwidth and latency are all big factors. Cache also plays a part.

Will more ram help?

No. I GB is plenty.

if the cache was bigger, would it count?

Yes, but not a tremendous amount. I also have a 1.8 GHz Duron that I\'m running on the attribution project now. When I tested it on the coupled model at the BBC site, it ran at about 3.25 s/TS. So, the difference between our two systems is likely the RAM latency, and the motherboard chipset. The RAM timings on that Duron system are 2-2-2-5. The motherboard is an NForce2 and the memory is running dual channel. If your RAM timings are considerably slower, say 3-3-3-8 and you are NOT running the RAM dual channel, then that would likely account for the difference.

The new PC\'s have fsb with 1 GHz speed. Is that important or is it the processor?

It\'s important primarily because the memory bus is running faster as well.

How much beter is a P4 than a P3 and so on

It depends. Old P4s that ran with RDRAM or SDRAM and/or were less than 2 GHz weren\'t much faster than the fastest P3s. As the P4s got a 200 MHz (400 MHz DDR) front side bus and dual channel DDR RAM, then they really took off.

Thank you for the answers. There is obviously a lot I dont know about computers. If ram is 2-2-2-7 or 3-3-3-8

I would lik to know more about this. Does someone know a good place on the internet where I can read about this?

Thank you

This is part of Tom\'s Hardware, always a good read on computer matters.
And this is another site which explains the numbers, perhaps without helping to understand what\'s best for you.

First, this is probably mentioned somewhere else, but I didnt find it..

I am going to byu an athlon 64x2 3800 since it (as it seems to me..)gives the most processing power for the money, and is a good OC-cpu.
I will tweak it and then I wonder if I should byu a certain type of ram. Is the type of ram given from the motherboard or will it adjust automaticly to fsb or other things? I want to byu an am2-motherboard for later upgrade and then I have to buy ddr2-ram?
I now have ddr1 and CL is 2 which is very good but ddr2, even expensive, have CL5. As I have understood ddr2 has higher bandwith (more MB/s?) Is it still better with ddr2 even if it has higher CL?
Another Q is: The fsb is on the motherboard but cpu\'s also come with a fsb-number. Why? and does this numbers have to match an m\'board and cpu?
And last: Is it better with a 10 000 rpm hd than a 7200 for cpdn or other BOINC-projects?

Thank you

Steinar

Hi,

An alternative you may want to consider is an Intel Core2Duo e6600, which can overclock up to 3.5MHz or so if it has high frequency memory and the right motherboard. It\'ll outperform an overclocked AMD (Honza\'s 6600 runs twice as fast on the model as my overclocked 4600+). AMD does give the best performance/price at the low end.

DDR1 (Socket 939) is not compatible with DDR2 (AM2 socket). I think X2 3800 is available in both varieties, but you need to get the matching one for your motherboard and memory.

AMD doesn\'t have a FSB as such, there are several different things you need to tweak to overclock them.

Well, you quoted 4.5s/TS for your old machine.
I have a new Intel Conroe E6600 based set-up and it runs at 1.6s/TS in standard trim (3 times the speed of yours and I have dual-core obviously, so I am doing about 6 times the work that you are in the same time!!!), but if overclocked, like I am currently, it is running at 1.25s/TS.
FSB/memory speed and clock speed are all interlinked. In order to get a higher clock-speed, you need to \"up\" the FSB. By doing this, allows the RAM to support the CPU better, if and only if it has sufficient overhead.

Neil.
