Asus P2B rev1.10 and P3-1GHZ

Got a motherboard here, the Asus P2B rev1.10. was wondering if I can buy a slot 1 p3-1Ghz running at 100mhz bus and just put it in there. I have the latest drivers from Asus for my board, 1013 beta? i forget which one but its the latest i know for sure. I think the P3-1Ghz has a 1.70 voltage requirement, on my asus board theres no manual way to adjust this. I would go with the sloket and Flipchip version of the 1gig and just use the sloket voltage settings, but I only have PC100 ram and i dont feel like shelling out cash to buy PC133 ram even though memeory is cheap, however im poor.

Also whats the deal with Tualatin cpus and the P2B? will those new chips work with my board and if not are there any plans in the future to adapt this ? I dont see a need to buy a new motherboard unless I REALLY REALLY have to since im cheap and poor.
 
first off, you're revision board offically doesn't support a coppermine but it may still work.
have a look at the numbers & letters on the top of the voltage regulator next to the atx connector.
here's the specs

IC Vcore range
HIP6004ACB 1.80V to 3.50V
HIP6004BCB 1.30V to 3.50V
HIP6019CB 1.80V to 3.50V
HIP6019BCB 1.30V to 3.50V
if your voltage regulator's Vcore range is 1.3-3.5V then a slot 1 coppermine will work.
 
You can use any Intel processor with a 100MHz FSB, or if you don't mind the AGP being out of spec at 89MHz, you can also use 133MHz FSB processors. The P2B does have a 1/4 PCI divider at 133MHz, so you do not need to worry about that either. Multiplier is NOT an issue, since all Intel processors are multiplier locked, and they will ignore whatever setting your motherboard has and use its own multiplier.

You must have the latest BIOS, either 1012 Final or 1013 Beta 007.

Depending on the revision of the board, you may or may not need to do a bit of tweaking for it to work. If you have PCB rev 1.12, it already has support for Coppermine voltages. Earlier revisions may not. In such cases, you need to use a slotket with an FC-PGA processor, and set the slotket to manually request 1.80 volts, which is the lowest that boards as far back as rev 1.02 can handle. This voltage is fine for Coppermines, and assists greatly in overclocking should you want to. If you do not set the voltage manually on the slotket, the system will not boot.

You can find the PCB revision printed directly on the board in small lettering next to the name of the board itself, located between the PCI and ISA slots.

Only some versions of PCB rev 1.10 support voltages lower than 1.80 volts. If you do have one of these (you can tell with the post given above), then it should be OK for a Slot 1 1GHz processor. Of course, it is always safer to purchase an FC-PGA processor with slotket to ensure that you do not run into any problems.

As for the Tualatin, it's difficult to know whether or not it will run on the P2B. The pin definitions are different, and the VRM is the new 8.5, not 8.3 (used for Katmai) and 8.4 (used for Coppermines). Either way, we will need to see if the slotket compensates for this and whether or not ASUS will release BIOS support.

Thanks for the info, im going to check my board in a sec. Btw i did do some searches on the forum to see if anyone else had this question and i noticed you just cut/pasted that line but what I really was interested in was that quote. That basically cleared it up for me. I would do the FC-PGA processor w/ slotket method but due to cash problems I dont know if I can do it unless it was my only alternative. I only have PC100 ram and i dont even know if my video card, Creative labs TNT 16MB can even run on an out of spec'd AGP of 89mhz. Anyways, if my board can handle the upgrade i'll be darn happy, this board has lasted me for many years.
 
Cash problems??

A slot 1 processor is more expensive than an FC-PGA processor. Putting an FC-PGA processor together with a slotket makes the price the same.

While I cut and paste the same post, it helps clear up the situation regarding the entire line of P2B boards. I simply append post specific information at the end if necessary.

The 1GHz processor is available in both the 133MHz and 100MHz FSB versions. You need not worry about your AGP running out of spec if you purchase the 100MHz FSB version.
