I NEED MAJOR HELP PLEASE.

I JUST UPGRADED THE CPU ON ON MY DELL XPS 410 FROM E6300 TO E6850 AND WHEN I TURN ON IT DOESNT BOOT JUST BEEPS. I PUT THE OLD CPU BACK IN AND IT WORKED FINE. WHAT IS THE PROBLEM?

THANK YOU IN ADVANCE

Moderator's Note: Don't use all caps!

The BIOS your are using may not support the E6850. Go to your product website (Dell XPS 410) and check for any BIOS revison available to support the E6850. I am not familiar with your machine.

One other thing. Take off Caps Lock while you still have it working.

alright caps is gone sorry, ok i found what the problem is bios is set to 1066 and my new processor is 1333, i read places that the bios could be flashed and other say its hardware, so i am not sure, if the bios is upgraded will it still run at a slower 1333 because i read that the motherboard does support it with the right bios, im confused

could i mess up the processor if the fsb is different or is it safe if the motherboard supports it

Call Dell's T-support, they will gladly help you out. They usually provide really good T-support.

Also as far as Dell BIOS goes, it's easy. Just put your service tag into the support area, then go to the downloads and download the BIOS that they have posted out there (it will be the most recent, don't worry about "which one to get" ). Then to update the Dell BIOS is simple, just double click the file you downloaded while you are logged into windoes, the Dell utility does the rest. It is more reliable than other windows BIOS update utilities and should go fine.

Your BIOS has many settings. 1066 most likely refers to 1066MHz, a RAM speed setting or possibly a CPU setting. 1066 does not refer to your BIOS revision. I am not familiar with your DELL 410. The symptoms you describe suggest your BIOS 'revision' your are currently using may not support the E6850. You should go to your Dell 410 website page and check for any BIOS revision listed there that supports the E6850. To be honest, I know nothing about the DELL you have, MB, chipset, etc. Your system may not support the E6850.

ok i just updated the bios from 2.3.1 to 2.5.3 hope this works

what i meant was that the old processor is 1066 fsb and the new one is 1333 fsb

Good luck, I'm at work so I will check back in a few and see what's going on.

same thing computer just beeps

doesnt even boot or nothing beebs as soon as turned on

With the latest BIOS revision I would say that your motherboard may be pre-P31/P35 chipset and may not support the E6850. Your going to have to get to the meat and potatoes of your motherboard compatibility and what chipset it has.

i cant find what motherboard I have, i read some where that dell modifies the bios specific to their systems being built

this is giving me a headache

all i want to know is if this can be modified or fixed by software like bios and settings or if this is a hardware issue, so i know im not wasting time and i dont want to mess up the cpu if its a hardware thing or the motherboard, the beeping is scaring me, i dont want to fry either

Install and run cpu-z http://www.cpuid.com/cpuz.php , that should tell you all the information about your motherboard/chipset that we need to know to help you.

Without doing any research on your specific machine this is my take: Most likely you have a 965/975 based mobo that only supports 1066 FSB processors. Your best bet if you want to upgrade your processor is to return your current one for one with a 1066 FSB. A dual core would be the safest option but a Q6600 should work as well and would make the best upgrade if possible.

You may want to consider just overclocking your current E6300 processor if your bios allows it. This can be dangerous but is usually safe as long as you don't increase the voltages. My overclocked E6400 runs faster than a stock E6850 without increasing the voltage past what is reccomended by intel (1.35 vcore).
