The L4S5MG is based on the SiS 650 Chipset. This is a great board and ECS shows much potential.

I want to begin by saying this: I will never, ever let a company control the view of this website. What does that mean? A number of sites on the net have this bias that is glaring because of the sponsors they have. While I know it is hard to keep a site running and they need these sponsors, but the sites should not say a company is great just because they give them money or products. This is just wrong, and if it is ever done here, I give you permission to find me and give me a virtual slap in the face. Anyway, enough of the ranting.

What a nice CPU, tiny too</center>

Welcome to the first review at ASE Labs that I didn't pay for the products. Well, that's not entirely true, but I digress. ECS was kind enough to send me not one but two motherboards based on the Pentium 4 socket 478 cpu. The two motherboards I received were the P4IBMS and the L4S5MG, based on the i845 and the SiS 650 chipset respectively. Since this was the first Pentium 4 review, and will be my first Pentium 4 cpu, I'll be using this as the base for everything else. You will see the slew of benchmarks I've used and I hope you will give me comments on which I should include and exclude. I chose to buy the 1.6a Ghz Northwood. I paid around $150 for it. Anyway, the reason I bought this were two fold, the price and the overclocking. More on that later. I later decided to separate this into two reviews, and chose not give a score because I cannot compare it to other boards so my score would be messed up.
