Pc2700 ram 333mhz reads 266mhz

[p4USER2112]

i have 2 1gb pc2700 unreg un bufferd no ecc for my hpd220 they are 333mhz each but my bios reads 266mhz on the rams i dont know what to do to help it read correctly please help anyone.

Its not really a problem your ram will run at whatever the bus speed of your processor is.

What cpu you have?

It depends on the CPU and the board. I had an old system that ran 4Gb of DDR400 at only 333. I found out I needed a Prescott CPU and a bios update, but even then, I saw little to no performance boost on the old 478.

its a celeron 2.4 128 400mhz but im upgrading to p4 2.8 512 533.. that is possible right ? well on a hpd220?

 

[saaiello]

Yes that will work on that board

 

[p4USER2112]

but my ram speed will it change to 333mhz?

 

[violentlyhappy91]

It should do. If it's only 533mhz I can't really say 'yes' though. If you had a board with support for 800Mhz FSB, then it would. I've got a few 3.0 Prescotts CPUs and a 3.2 Nortwood sitting around at home. Just got my server running 333Mhz with a 3.2 Prescott OC to 3.8 and 4Gb RAM, but it won't go to 400Mhz, the reason is that an old board isn't able to use everything to it's full potential.

You won't notice a difference between 333mhz and 400mhz with that chip anyway.

 

[p4USER2112]

so im better off getting a new board that supports 800mhz? ...is there a special pin mod for the 478 cpu like to speed up the fsb?

 

[violentlyhappy91]

Getting a new board...good luck finding a good condition one, if you can find it, go nuts. There's no pin mod, just the Northwood CPUs that support hyperthreading, or Prescott CPUs. Northwood is slightly better when gaming, or basic tasks, but Prescott can be overclocked with little to no rise in temperature, however it can cause your capacitors to go boom. You can tell the difference between Northwood and Prescott by the L2 Cache. Northwood is 512kb, and Prescott is 1Mb. Good luck with it.

thanks man
