it will fit the socket, but since it's "new" 45 nm technology, it won't work without a BIOS update. are you sure there's no updates? These 45nm CPU's came out quite a long time ago.
Ok! Ok, The Motherboard update came out on 7/2009 v5.22 for this motherboard. I have v5.22 installed already. I want to know if this CPU is suported now! You can see the update is very recent.
High % Rubbing Alcohol and Cotton Swabs / Q-Tips. If it doesn't come off on its own (after removing the screws), you can try turning it gently back and forth. If it won't move, let the computer run for a bit to heat the CPU/Cooler up and loosen the paste.
Also you can use a hair dryer and warm/ heat up the cooler slightly, then the cooler should get loose easily, like twiz said, use some alcohol to clean the DIE itself.
Update! I installed the CPU in the motherboard and guess what, the Motherboard is compatible with the E8400. It works beautifully. Also when you installed a CPU which has VT technology the motherboard will give the option to turn it on. I'm so happy! So if have the MS7525 and you are looking to see if you could upgrade your motherboard with a CPU higher than the E7XXX, you are able to! Like I said HP won't said all the CPU's the their motherboard supports. Nice
I only joined this forum to post this sole message for future readers of this board, because this thread helped me. I took apart my girlfriend's HP to find this lovely motherboard with an e4300 processor. I felt that it might be able to stand an upgrade, so I did the research, and like the OP says HP does not list whether any 775 processors work beyond the e7xxx series. I just got an e8600 processor from ebay for like $40 and popped it in. No jumper settings required changing, and it ran like a champ. It took 50% less time to boot Windows. So this confirms that the e8600 processor works, just in case you all have these ms7525 boards and are looking for a cheap upgrade. Well worth it. So the next question is, what lucky stranger will try out an Intel Core 2 quad like a q8600? Any guesses on whether it will work?
I have this same board with a E6600 Core 2 Duo (not on the list) and it works great (with 5.22 BIOS update). I also have a Q6600 Core 2 Quad that I tried to install and get a message that says that the cpu is incompatible. I really do not want to buy another board. I'm just looking for that extra umpf.
You will need to update your bios again that includes support for your CPU, if you cannot find one on the site, then you may have no choice but upgrade to a new motherboard.
i.imgur.com/BQ0ZgeP.png i.imgur.com/Gm9tgRN.png i didnt even need to update the Bios. Intel Duo E8600 3.33GHz fully working on MS-Boston 7525.
its actually 4 months old but i assume u cant read properly anws, i bump this cuz it helped me out and just in case a future reader is passing trought the same problem will know that MSI Boston 7525 is fully compatible with Intel Duo EE8600, a CPU that is not on the official LIST of that board.
Now that it is actually 5 years old, I found it fitting to say this post gave me assurance to order the E8600 for MS7525 Ver 1.0 Bios 5.14 from the factory. As stated, the E7xx are the highest supported LISTED core 2 duo on that mainboard, meaning theoretically there might be a few scragglers thinking they're using all the board has to offer out there. To those select few, I say it is time to upgrade as this chipset is far irrelevant. Anywho, thank you Raul for your counsel, and you caffeinepizza. and to answer your question, i do. i do.
