Hi everyone,what CPU can I upgrade to based on my system below? Dell claims 2.8 at max in their documentation, where the below Powerleap system scan claims 3.06. Who's right?

Supposedly www.intel.com has a place on their website to tell you this information. You can also download the MOBO spec sheets.W. Sieffert

According to Intel, it will take up to a 3.06ghz cpu. Make sure you have good cooling if you decide to install it.

Thanks for the replies guys.I've had others tell me the increase in CPU cycles going to the 3.06 would not translate to that much better performance (FS2004) because of the front side bus speed (533 in my case).I was told a better way to go would be with a mobo upgrade that supports 800 FSB speed and the appropriate processor - that would yield greater performance - do you agree?Thanks,

"I was told a better way to go would be with a mobo upgrade that supports 800 FSB speed and the appropriate processor - that would yield greater performance - do you agree?"Yep. Given the choice between increasing CPU sped or FSB speed, an increase in FSB will always yield more system performance.Greg

I have 1 gig of DDR PC2100 memory in my current box. If I put that memory and a P4 3gig+ 800FSB processor into a motherboard that supports it, would the slower memory cripple the system? Or do I absolutely need faster memory to take advantage of the faster FSB speed? I'm new to alot of these terms, so go easy on me ;-)I'm trying to save money where possible, especially seeing as I upgraded my memory only a couple months ago.Thanks for any help.

"I'm trying to save money where possible..."No problem there... we all are.Having said that, the PC2100 would not make your system happy if you upgraded to a 800Mhz FSB board.Your current board is a quad pumped 133Mhz FSB design. The PC 2100 is perfectly matched for that. Wouldn't be the case with the 800Mhz board (200Mhz quad pumped). It will be happiest with PC3200 (200Mhz) memory.An 800Mhz motherboard from a manufacturer like ASUS or Abit using the Intel 865 chipset would be a very good choice. Also, Newegg is currently selling Kingston and Corsair PC3200 512Mb value RAM for $75-$80.00.The key is in creating a balanced system. To do that often requires upgrading more than just one component. It's the nature of the beast.Hope this helps,Greg

If you replace the MOBO in your Dell be sure that the connections on the power supply's main ATX power connector are laid out in accordance with the ATX spec. I read a post (I think in an AVSIM forum) that on some Dell systems the power supply and MOBO connections are not standard. The result is that if you change to a normal ATX MOBO or power supply the board will be destroyed. I have no idea whether this is true or not, hopefully someone will give you a definitive answer.David
