Where can I find Bios updates? Chipset updates? My processor for my Foxconn NT330IABNAA NVIDIA ION (4GB RAM w/ ReadyBoost) is not performing as I have read.

there is no answer to that. no 2 CPUs on earth overclock the same amount nor way.
best is not OC< and learn to just compute and be happy?
old chips sets are 4GB max ram and useable to 3.2GB
the data sheet on your PC, for the north bridge tells you that
it PCI devices, or iGPU can steal RAM from main, to form up. vRAM
it even says the word steals. (intel pages)

find OC forum real and read. 1billion words to nowhere fast.
have fun with BSOD , endless. and random or hard worked hot.

Click on the Specification tab.
Notice under the Processor heading - Chipset.

The motherboard chipset is an Nvidia GeForce 6100 chip, and Nvidia nForce 410 chip.

[ Chip and Chipset are slang terms for I.C.

Short answer?

Yes.

Good day,
According to Intel 945G chipset supports Celeron D up to Core2Duo. Intel Gigabyte's 945 DS3 even supports up to Core2Quad. GByte Foxconn has 3 mobo bios from there site. Foxconn
According to their date: Latest to oldest
4BFF1P56 No Version 4BFF1P40
Have you tried installing the no version bios? In my experience some latest bios have some problems with other devices so try to use the no version bios. or try a different mobo bios with the same chipset from Foxconn. below are two foxconn mobo models i can't see the difference.
945G7MA-8EKRS2 945G7MA-8EKRS2H
Update at your own risk..
hope this helps, thanks for posting.

The k8n supports a max of 4GB Ram but to be able to access all of the 4gb you need to have a 64 Bit OS or you can only access 3.26 GB.

This could simply be an issue with you bios. Flash to the latest bios version.
From the site it looks like the Mars has had some bios issues in the past.
Nice setup btw

First need more info on your setup. your puter may not support 4gb. If it does do you have the right ram. Make sure ram is same type. If so take ram out & reseat it. Make sure to shut down & unplug power from back of computer. If this does not work try putting one stick in & start puter
