When it comes to overclocking processors, it seems like the Celeron is by far the most overclockable CPU. There are several reasons to this. Because the standard FSB currently is 66MHz, the other hardware such as RAM, video card, and harddrives don’t have to deal with extreme overrated frequencies. Overclocking the Celeron 466 to 581(7x83FSB) gives us an AGP-speed at 83MHz. No harddrives should have any problems even, with UDMA enabled, neither would my AGP-card. In addition, with the 83MHz FSB, you don’t need the expensive PC133RAM, just plain PC100. However, when running FSBs between 83 and 100 MHz, you might experience problems with your hard drive and other peripherals.
Different plants also have higher success rates, with Malaysia producing the most stable Celerons available. The Costa Rican version also has some moderate success but data indicates the Malaysian version to be stable a higher percentage of the time. Understanding what the numbers and S-Code means on the Celeron will help you identify specifically what type of Celeron you have or need to purchase. These identifying numbers can be found on the bottom side of the CPU.
In this case, I have got my hands on a Boxed SL3FL Malaysian CPU. Its full FPO/Batch # is L9160680-0684.
The first digit is the location of manufacture. This should be a 0 for Costa Rica and a 9 for Malaysia. The second and third digit indicates the week of manufacture, week16. The S-specs indicates whether it is an OEM or retail processor. It should be SL3EH for an OEM processor and SL3FL for the retail version.
General specifications cut’n’paste, as published by Intel on Celeron 466:
|SL3FL, Processor CPU ID Information:|
|Max. Bus Frequency (MHz)||66|
|Max. Core Frequency (MHz)||466|
|Case Temperature||70° C|
|Socket Type||370-pin socket|
Next thing to consider is which mainboard to choose. I have always believed in ABIT, and therefore ABIT it is.
Q1: Single or dual mobo?
A1: Depends whether you are planning upgrade to a dual system later on or just buy an Athlon 1GHz in a few months.
Q2: Slot1 or socket 370?
A2: If you have a slot1 mainboard, you’ll need a Slotket (converter PCB) and there are a few brands out there. A friend of mine had the choice of two, but it didn’t seem to be any "significant difference". However, he was very impressed with the MSI MS-6905 (can also be used for dual mode). This one has jumper settings on the converter PCB from 1.8Volt all the way to 2.6Volt. It also had jumpers for single/dual CPU mode and an overclocking jumper which "virtually set 66MHz to 100MHz. If I go for the socket 370, I have to buy a new heatsink-combo, because I can’t use my old slot1-ALPHA.
Consider your motherboard as a tool. With good tools, you’ll have better results. When I decided which mainboard I was going to buy, I wanted FSBs. Lots of. UDMA66 wouldn’t be too bad either, so in fact there was only two ABIT-board I could choose. ABIT BP6 and BE6-II. I went for the BP6.
