I hold a A.A.S in network technology, a A.A.S. of Telecommunications, a B.S. of Technology with Networking, and am rapidly approaching my M.S. of Technology.
I would NEVER knowingly steer somebody wrong on a technology question when all the answers are to be found ONLINE with a bit of judicious research.
Please accept my apology if I offended you with my first reply...but I'm not a jerk that runs around posting willy/nilly..(.I'm NOT saying you are, I'm just saying I do my research first..).without thought as to if the person asking for the advice can afford to get a wrong answer and then run out and spend a large chunk of their budget they may not have...only to find out I lied to them...that's not acceptable to me or any ethos of decency and honesty in these types of forums...I've been a member of more clubs online than I can count for better than a dozen years and my track record for appropriate answers is pretty decent...I'm also listed at LinkedIn, Cisco, Techspot, TomsHardware, and on and on, I have a technet membership, I have taught Cisco Networking classes, I don't believe I'm making a mistake in what I stated above and I believe that I'm 100% corrrect in saying that the Chipset capabilities, the CPU fsb, and the type of socket ALL must be compatible...you can sometimes down clock your ram....but the cpu fsb and the chipset speeds must MATCH or be compatible...the lenovo mentioned REQUIRES a 800 MHz architecture to function...the bios will NOT recognize a cpu that isn't compatible with the chipset in speed...ie...fsb. I gave the individual the correct answer to his question and that in general is how DDR II and all it's associated hardware have ALWAYS worked because that's the way they were designed...now the cpu architecture isn't designed that way and because the modern cpu IMC talks DIRECTLY to the memory and a FSB isn't utilized any longer per this:

Read Note (2) below to clarify the difference of having a IMC...integrated memory controller... in modern cpu's utilizing DDR III and associated architecture versus using DDR II and it's associated architecture!
What Chipset Should I Choose?
The motherboard usually has 2 chipsets
1. Northbridge - for Intel LGA 775, it holds the Memory Controller and the PCI-E Controller. The Northbridge determines the type, maximum amount, and maximum speed of memory. It also determines the number of PCI-E lanes that will be available.
2. Southbridge - it handles the Input/Output devices (keyboard, mouse, gamepads), storage devices (HDD, SSD, USB) and other components of the PC
Modern AMD and Intel CPU's now have an Integrated Memory Controller. So it is now the CPU that determines the type, maximum amount, and maximum speed of memory. The Northbridge is now only left with the function of supplying the PCI-E lanes. Modern CPU's don't use the FSB anymore, they now communicate directly with the memory.
For Intel LGA 1156 motherboards, there is only one main chip - the Platform Controller Hub. It functions more like a Southbridge and the 2 common chipsets are P55 and H55. The main difference between P55 and H55 is that H55 allows the use of IGP's of Intel Core i3 500 and Core i5 600. Using a Core i3 500 or Core i5 600 on a P55 board is possible but the IGP will be disabled. All LGA 1156 processors are compatible with P55 and H55.
Intel LGA 1366 boards still has two chips- the Northbridge and the Southbridge. It only has one type of Northbridge - the X58. The X58 chipset has 36 PCI-E lanes but this becomes only significant in a multi-GPU setup.

Glad to help! I agree with the desktop decision...the upgrades are usually considered to be within the acceptable limits of wattage usage and heat production if the upgrades are coming off the official manufacturers tech support pages!![hellokitty[hk]](/community/data/avatars/m/169/169488.jpg?1355088591){kind=avatar}
