CPU Upgrade for Core2 Q8200 CPU to XEON 5450

[marcgoldbergnj]

Hi, wondering if I can upgrade the CPU in my old Dell Studio 540 from Core2 Q8200 to Xeon 5450?

Unfortunately not if you don't intend to upgrade the motherboard aswell, the Core2 is connected to the motherboard using a LGA775 socket, in other words your motherboard has a LGA775 socket and the Xeon E5450 requires a LGA771 socket not a LGA775 socket and therefore is incompatible with your current motherboard. If you wish to upgrade the CPU you should also upgrade the motherboard. but as far as I know the Xeon is also a server CPU and therfore very expensive.

Google is your friend. Start here and read it very carefully: http://www.delidded.com/lga-771-to-775-adapter/ In Tested motherboards section, search for "Dell Studio 540".

Edit: It would be easier to install a Q9650 since they are not that expensive and no socket modifications and modded BIOS are required: http://www.ebay.com/itm/INTEL-Q9650-Core-2-Quad-3-0G-12M-1333Mhz-from-Xeon-E5450-SLANQ-LGA775-CPU-/271704344812?pt=LH_DefaultDomain_0&hash=item3f42d748ec

The E5450 can be found for $50.

Xeon E5450 (with "mod") installed on my Dell Studio 540 (Q8200), working perfectly and without errors.
I have only one problem, the CPU fan runs at full speed ... but HWMonitor reads normal temperatures around 45 degrees in the cores.
I write these lines with this configuration.

If the fan was working fine before, the issue may be caused by the CPU that isn't fully recognized.

Well, it depends where you are I spose. The 9650 in that ebay add was $50 , its the same performance benchmark wise , it doesnt need a mod widget that costs another $10 and your fan would run normally.
But congrats, anyway.

If read properly, you'll find that "The 9650 in that ebay add" is exactly the same xeon 5450 as any other, someone has just carved two notches into it and modded the appropriate pins, so that it can be directly inserted in s775. So you don't have to cut the plastics around the socket, but it doesn't make any difference otherwise. Real 9650's still run much more expensive than that on ebay.

EDIT: just noticed how old this thread is... sorry for spamming

Not quite. It is always a good idea to check in CPU-Z to see if your XEON is actually running at the speed it is supposed to be.

The XEON E5450 will boot in a Dell Studio 540 (latest BIOS), but it will run at 2.33 GHz instead of 3 GHz. This is due to the fact that it isn't recognized properly by the BIOS and will run with a 7x multiplier instead of 9x. However, the same board (IPIEL-RN2 0M017G) will run a Q9550 with an 8x multplier, a Q8300 with a 7.5x multiplier, a Q8200 with a 7x multiplier, and a Q6600 with a 9x multiplier.

Basically, this board will boot with the XEONs, but they aren't recognized properly and do not run at the correct speeds and are likely unstable.

Unless the user I'm quoting modified his BIOS to support XEONs (which he did not mention), his CPU was running at only 2.33 GHz.

Just installed a E5450 on my studio 540. It runs a 3GHz without having done anything.
Unfortunately I have the same fan problem.

Again, you aren't listening. Yes, Windows will say that it is running at 3 GHz. CPU-Z will say 2.33 GHz (the actual speed that it is running). Please don't post misinformation here.

The fans running too fast are a result of the fact that the board DOES NOT properly recognize the CPU. If it was properly recognizing the CPU, the thermal sensor would be correctly communicating with the motherboard and the fans would not be doing that.

You have contradicted yourself and you don't realize it.
