Need specs for the N15235 motherboard.\r\nIt has a

i don't know what computer you have

You need to update the Bios to the latest version to recognize that cpu. You can get it here:

Hi,
Welcome to Fixya. If you want to upgrade your Processor you can use a dual core cpu. I proivded the list of processor that is compatible with your motherboard. By the way the socket of your motherboard is a LGA 775
Lga 775 Processors
Thanbks for using Fixya.

No since this is a older mobo the manufactre only recomndes you use Pentium D, Pentium 4 HT, or Celeron D. many people have tried this and have had alot of problems and little success.

Socket LGA 775
Supports Intel Core 2 Duo/Pentium Dual-Core/Celeron Dual-Core/Celeron 400 Series Processor
Supports FSB 800/1066/1333MHz
Support Intel Hyper-Threading Technology
FSB 533MHz is not supported by this motherboard. CPU TDP over 65W is not available. Please refer to CPU support for further information.
hope this helps

The LGA 775 processor socket doesn't matter, calderwooddu.

It's up to the motherboard chipset, and the BIOS program, and version, of what that Foxconn N15235 will support. I would go back to the Pentium Dual Core E2160, use CPU-Z from CPUID.com, (Free), and see what the motherboard chipset is, first.

(Motherboard chipset: The Northbridge, and Southbridge chips. Chip is slang for I.C. Integrated Circuit)

The Northbridge chip is what determines what Processors are supported.

1) http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

2) http://en.wikipedia.org/wiki/Northbridge_%28computing%29


Since the E2160 is built upon the 65nm technology, and the E5400 is built upon the 45nm technology, the Northbridge chip of the Foxconn N15235 may not support the E5400.

With the technology change are also Instruction Set changes. Plus other parameter changes. The BIOS program, and version on the Foxconn N15235 may not support these, either. Sorry to be a bummer.

Not a solution per se, Yet.

Need to know what computer this Foxconn mobo is out of. (MOtherBOard)
OR, if you get the computer operational again, let's use CPU-Z to see what the motherboard chipset is.
Need help in downloading, and/or installing CPU-Z, post in a Comment.

Assuming the CPU you have is an E5300 2.6 duo 45nm then use an LGA 775 mobo.

For Win XP / Vista run at LEAST 2gb (Preferably 4GB) Ensure the mobo specs are compatible with the type of ram also.

Most major manufactures use motherboard designed to their specs and upgrades to the processor are limited. You can use software such as Belarc Advisor, to determine what motherboard you have and then you can search the net to determine what processors are compatible with it.

This particular CPU is not on the list of processors supported by this board. See "CPU Support List" tab:

ASUS P4-P5N9300 Spec

How to install Socket LGA 775 CPUs:

Lift up the cpu slot load plate (which covers the pins and also locks the cpu in place) and install the processor slowly, vertically and carefully into the socket without bending any of the tiny pins in the motherboard socket. Lock the load plate.

The advent of the LGA 775 form factor moved the tiny pins from the CPU to the motherboard socket. Great for Intel, not so great for motherboard manufacturers. Now bent pins are the responsibility of the board makers. Customers with bent pin problems are no longer contacting Intel.

The further down you go the stronger the CPU.
When looking for the CPU that you want, you'll also need the bios version listed across from that CPU.
