Mobo/memory/cpu help please

  Jakey boy 10:07 29 May 2004

Ok, hope someone can give me some guidance here. Mobo is Asus P4S800 (SiS 648FX chipset). Am considering P4 3.0Ghz CPU (Northwood or Prescott?) and 512mb Ram. I'm confused as to
a) Which Ram would be compatible
b) Northwood or Prescott CPU

Also, I have already got a Q-Tec ATX 300w psu. Would this be powerful enough, given the intended specs? Haven't decided on a GFX card as yet, but HD will probably be at least 80GB to start with. Any help?

Your mobo will accept northwood & prescott designs

the ram is dependant on the FSB of the CPU

If you get a 533fsb CPU then pc2700(333ddr) ram

If you get a 800fsb CPU then pc2300(400ddr) ram

The higherthe number the better so if can go 800fsb not much price difference between them now..

Prescotts use more power and produce a little more heat

I would surgest a 400w + PSU and higher if you get lastest gfx as need extra power...

80gb would be fine unless you do a lot of d/loading (BB) or video editing

One question do you have a D on the end of your model number or not?

As to the RAM question, go to click here select UK from the drop down box at the top left of the page, enter your mobo in the Select Manufacturer box and follow the steps. Order your RAM direct from Crucial - it's the best.

No idea re the processor, I use AMD

Thanks, I know about the fsb, am going for 800. And 400DDR. It was the manufacturer I was concerned about - brand or generic - big difference pricewise! "D"? On the mobo? No, just P4S800.

thanks to you also. I have used Crucial in the past, and I agree they are one of the best. A bit pricey tho, compared to other outlets.

If going 800fsb then get pc3200 ram like johnsims said crucial selector will show all ramthat will fit urboard but you will select the 3200 viarity to get best performance..

With regards to cpu do you have a budget and what do you wish to do and also would you want to overclock any time?

  ste_bla 10:47 29 May 2004

They maybe pricy but lifetime gaurentee you CANT get better than that, only other RAM I would consider would be Crosair or Kinston and all their prices are roughly same...

  Jakey boy 10:56 29 May 2004

Have checked crucial, and they confirm the best for the mobo. Not too expensive either. ste_bla - No budget really, happy to pay about expected £150-£200 for retail inc fan/hs. Overclocking? Nah, over my head i'm afraid ;-D

Not sure on GFX card yet. Installed nVidia GeForce 5200 in current main system recently, and am comfortable with it's performance. Not a big gamer really, but do like to get the high-end graphics titles when I can.

silly me i canna read properly...

I think the Prescott has a larger secondary cache (1Mb vs 512kb for the Northwood)

What that means in terms of performance - I have no idea !
