Locked

Motherboard

By JVBerryman ·
My question is likely very elementary to most of you, but here goes... I have a DELL PC with a Intel MB and 1.7 processor, 400 front side bus. I want to use a faster processer (2.4) but it wouldn't work. I am seeking advice and location of stats on the MB / processor relationship and compatability. The 1.7 processor is either a Northwood or Willamett processor, and I believe that match is my problem. Can someone help.

Thanks.

For most OEM motherboards, your only source of support is the system manufacture.

Log into Dell's site with your model and serial number to access as many details as are available.

See what CPUs Dell lists as upgrades for your system.

You may need a BIOS update to be able to recognize newer CPUs.

It is possible that your board only supports the 400MHz buss speed.
If so, you need to specifically shop for CPUs with a 400MHz FSB.

Even if your motherboard supports a faster buss speed, you may need to install faster RAM before you can raise the buss speed.

Assuming that you are limited to the 400MHz FSB, this P4 may be what you need.

DELL doesn't give out info. I suspect I am locked at a 2.0 ghz P4. The ram is locked at sdram pc133.

Thankks for the input. That MB item suggested looks like the one I tried. Current CPU has 256 L2 cache. That one has 512. I don't know if the cache is the problem or not. I am aware of the 400 FSB. Is there a utility to identiry a motherboard somewhere?

Thanks again.

Motherboard cpu capabilities is often decided by the front side bus and the controlling chip set. If you put a 533 fsb cpu in a 400 fsb motherboard the cpu will usually perform at the 400 fsb level, that is under perform.

Your problem is most likely due to the controlling chip set not having the control commands to operate the faster cpu. Check you motherboard manual (or the manufacturer's website) and it will tell you if that motherboard is rated for a cpou of that speed and type.

There are motherboards around that will accept Celeron processors, but not P4 s of the same number of pins and speed. Also some motherboards that will handle up to 1.8 processors but not 2.0 or faster. I suspect that your board is not rated for the faster cpu.

I haven't had that problem with Dell. If you are still under support they should give you all the information they need. At the very least you can enter your Service Tag number at their support site.
If you only have the motherboard and NO Service Tag, try calling until someone talks to you. I bought a Dell server motherboard on e-bay and seller wouldmn't give me the service tag so I kept calling with the Serial Number until someone told me it was a Poweredge 2400. Be persistent.

If youhave the service tag put it up here and I will trying requesting info from my Account Manager??

I have been all over DELL support and find only basics, no detail on capabilities and max, etc. I want to put a 2.6Ghz in the 400 FSB. My guess is that it hasn't been tested by DELL, but the DELL boards suggest it will work.Thanks

Go to Intel's site and cross ref your CPU for specs, FSB speed and Vcore voltage. Most OEMs wont support user or third party upgrades. Your MB may not support the new CPU.

Your MB must support the FSB and voltage requirements of your new CPU, if the chipset/BIOS does not you need a MB that does.
