I have tried a Intel x5365 and it always comes up as a unsupported CPU. I am running BIOS revision A08. Is there more magic sauce involved such as a non-general release BIOS rev?

Okay. If when some one searches the Internet for an answer Dell 490 Upgrade options. I can confirm the fallowing. Xeon X5355 2.66 does in fact work in Dell 490 with the last available update. Quad Core. 1333 mhz bus 8 megabyte cache. X5365 3.00 Works.

Tried a a few Eseries Xeon Quad Cores 2.83 3.00. No go. Dempsy 3.7 ghz works dual core. Next will try a Dempsy at 677mhz 3.00 ghz. Going to pad mod BSEL and jump the fsb to 1066. Possibly 4.2 ghz.

Will try tonight. Pad BSEL  1066 3.7. Jump it to 1333. will post my results !

Bios should be updated before CPU change.

CPU's should be Matched Sets where the S Spec is the same.

Then with the correct parts  

two 2 GHz Dual Core Xeon 5130 processors,

two 3 GHz Dual Core Xeon 5160 processors

two 3 GHz Quad Core Xeon X5365 (Clovertown) processors

I believe your 490 will work fine with any 51xx cpu.  The 5100 series is dual-core, the 5300 series is quad-core.  As I understand it, all Precision 490 systems will run the 5100 series dual-core chips, but there is a mysterious motherboard revision that allows the use of the 5300 series quad-core chips.

I currently run my 490 with the chips you are looking for, the 5160 dual-core 3.0.  Twin cpu's each with 2 cores.  I just purchased two of the 5355 quad-core chips to replace my two 5160's, keeping my fingers crossed they work with my motherboard.  The twin 5160's are great, there isn't much I can do to really max out the power, until I start encoding video, and that is what I built this machine to do, and even now it does it very well and at high speed.  I should get my new cpu's in a few days.

Definitely make sure you get matched chips, meaning same revision and stepping numbers. 
Revisions run by these SL9RT, SLABS, and SLAG9, in alphabetical order from oldest to newest, meaning the SL9RT (max temp 56.5c) is older than the SLAG9 (max temp 65c).
Stepping numbers are either B2 or G0, I suggest the G0 because it allows the chips to idle at a lower wattage (less power and heat).

I would also look at your bios.  I just updated mine to A08 (newest) from A06 with no problems, but it probably wasn't necessary.  I think you want A06 or higher, that revision added support for new processors. It won't change the motherboard accepting the quad-core cpu's, but it might help ensure the dual-core's work for you.

A06 fixes:  1. Added support for new processors 2. Optimized memory allocation for Option ROM and PCI resources 3. Fixed BitLocker BIOS issue running with Vista SP1 4. Improved SATA device name strings in Setup and Boot Menu 5. Improved memory block attributes at E0000h after booting 6. Updated BIOS to support chipset errata 7. Fixed optical drive boot issue with drives attached to SATA port 4

A07 fixes: 1. Vista SP1 support 2. Miscellaneous fixes for PCI and PCIE devices 3. Fixed POST message with a single Intel(R) Xeon(TM) processor installed in the CPU1 socket

A08 fixes:  1. Improve OS licensing handling.  get it at    http://www.dell.com/support/drivers/us/en/04

Hi

Many thanks for such a detailed reply.  Have already updated my BIOS to the latest revision. I read elsewhere on this forum that to run quadcore's you need to have the "Clovertown" DR054 mobo.  Hope thats of some help to you.  Lets know how you got on with them.

Hi.  This is a follow up question to my Dell Precision 490 CPU upgrade.  Would the following Intel Xeons also work:

Intel Xeon 5060 3.2 GHz dual core Socket 771  SL92A 4M/1066 64-bit

Thanks

Hi,

Searching the internet found this thread. Am about to test several different versions of Quad Core's on a Dell 490. Have two 490's. The first one I upgraded to Intel X5355 Quad core. After updating the Bios. Purchased new $50. each with shipping.

They are plentiful and inexpensive on Ebay averaging $40-$50 for a used matched pair. The board revision that accepts the Quad core Xeons on the 490 as far as I know is GU083. Both of my 490's have this board.

Now. I have 4 T7400's. Decided to upgrade them. The faster processors are still too expensive.

So tried what is known as a BSEL modification. Took a E5450 pair. "13333mhz" Covered the correct Pads with tape on each processor. Well they now all boot at 3.5.5 ghz. 1600 mz. With Set FSB can go to 3.8 ghz. Best to stay at about 3.6gh

though. More Stable.

The Dempsy Xeon 3.7 Dual core is found on dell 490's being sold on Ebay. These have a 1066 bus not like your original chips. I have the same pair as you. No time tonight. This is an oid thread also.

Since the 490 has a 1333 mz bus. Why not look at the Xeon List on Wikapedia check out the Dempsy's. they have Hyper threading. I bought two of Ebay shipped $20.00 3.7. Bought a few more Dempsy's $5.00 and $6.00.

Will try them in a few days. If I am lucky and no VID Pad Mod(Volt Modification) is necessary. BSEL 1066 to 1333. Will take this dual core chip to 4.5 ghz. My bet is the Dell 490's being sold by Dealers on Ebay with these 3.7 mz Dempsey's

are the revisions that will not take quad cores.

Dempsey's have Hyper Threading . So at 4.5 ghz two threads with two virtual threads. It might out perform or equal a 2.66 ghz Quad core? Have to sleep. Will play tomorrow and see what works and doesn't. Then Post it here.
