Re: Question for a Precision 690 Quad-core owner...
The part number and revision did not change in the transition from dual to quad cpu support. It was the manufacture time of the board that mattered. I originally had two dual cores and changes to dual quad cores but was evidently lucky that I had the board capable of doing quad support. Mine came with a creative labs x-fi sound card and until I took that card out it would not boot through so the BIOS could reconfigure itself for the new CPU's. Before that I kept getting an unsupported CPU error message. Let me know if this is why you are asking.
I found a blog of a person with the older 690. I asked about which version He has and the person identified it as ODT029 (the old version that is not supposed to support Quads) And he is running it with dual Quads 5350s.
SO I want to say its possible to run quads with DT029 and probably with the F9394.
Yes, I am aware of the solutions you can use in order to get an incompatible motherboard working with a quad core, but at the end of the day they are only temporary. I don't have full data on what is different in terms of functionality between the different revisions of the x5000, but I think it is fair to assume that Dell hasn't put the restriction in place for fun.
For those of you that don't know, you can get a both a DT029 and F9394 motherboard 'working' with quad-core CPUs.
For F9394 motherboards: Any BIOS revision can be used, when you get the "incompatible processor detected!" message unplug the machine from the mains and remove the clock battery. Wait for at least 30 seconds before re-inserting the battery and then restore the power. The machine will operate normally up until the point where it is unplugged from the mains, at which point you will have to repeat the procedure.
For DT029 motherboards: The same as above except you must be running BIOS revision A01 (A02 is a possibility but untested) or lower. If you only have a quad-core chip you will need to find a dual-core CPU to downgrade the machine with, the battery removal trick will not work if you have upgraded the BIOS past A02.
Having said all the above, I have not tested every permutation, and am eager to hear your results.
If you go to the Blog site you will see that the DT029 is running dual quads fine with BIOS A01 and the user used that battery trick to downgrade bios with the quads installed. He also mentioned that the battery solution was only needed with A06.
Dont you think that is strange. Seams Dell is crippling the boards.
More on DELL:
I think it is more of a Sell strategy. Dell wants us to upgrade to T7400 platform to get into the peryn quads. If the equipment works with just the battery trick there is no reason for it not to work all the time ecept that Dell dosnt want it to work. All is needed is a BIOS upgrade to the latest Intel microcode and its done.
I cant believe such a company is doing such unapplealing thing to their customers.
Consumers have rights too and Dell needs to know about our dissappointment.

As I said in my previous reply, we have very different definitions of the word 'working'. To assume that Dell disables certain motherboards capabilities just for profit is puerile, especially considering the line in question (P690) is not explicitly denied more recent CPUs in its most recent incarnations.
However, I will agree that Dell are extremely poor when it comes to making these compatibility details known to their customers. It really shouldn't be our job.
Bottom line is that Dell outsources the manufacuring of its components to other companies (the competition has the same procedure) and looking at other 5000x solutions I have seen BIOS updates that enable even penryn family compatibility.
Definately support is not Dells strong side - and its a shame on DELL that one has to come to a Forum to learn which equipment works with what. I dont understand why that should be a secret?
Thanks for your reply and sorry for Hyjacking the thread.
I didn't consider your post to be hijacking the thread, it is certainly on-topic.
I would be interested if you have any links to back up what you're claiming though; that x5000 based multi-processor solutions (that have been available for as long as the 690) by other manufacturers have no compatibility issues with 53xx and 54xx series CPUs. Simply stating that other manufacturers current x5000 based solutions support quad-core CPUs is inadequate.
