Just a note that VOGONS isn't intended to be used as a marketplace. Please don't use it for any personal buying or selling.

In regards to obtaining specific processors, my recommendation is setting up an Ebay search for specific processors. This way you will get notified when one appears for sale.

You could also try the Amibay forum (https://www.amibay.com/), since that forum is intended for buying and selling vintage hardware.

My bad, didn't mean to break the rules.

EDIT: Followed your advice and joined the amibay forums, thanks.

Mods can delete this thread if it's against the rules, again my bad.

Btw, why is this? Many other forums have a buy/sell subforum...

No worries, it was just intended as a friendly notice of the rules here. 😀

My understanding is it's to avoid the headaches and potential liability that comes with individuals undertaking commercial transactions.

Invariably with enough buying and selling, there will be deals gone wrong which will lead to disputes between members and potentially increased moderation activity. Disallowing buying/selling helps avoid that.

If you look at Amibay, they have an elaborate set of rules to govern buying and selling activity. It's a lot more overhead to try to manage.

Another issue is fraud. vcfed allows trading, and doesn't have the capacity to keep a close enough watch on people selling things they don't actually own using pictures scraped off of Facebook marketplace. So it's more trouble than it's worth, and best to keep off of vogons.

Hello,

I have a P6BAT A+ rev 2.2 motherboard so I'm stuck with 100mhz fsb

I think it's easier to just set the existing CPU's FSB to 133 MHz.
There's a 95% chance a 600 Coppermine will work at that speed.

From the motherboard's datasheet there is no support for 133 FSB, nor is there a way to modify the multiplier in the bios, at least none that I can see.

Depending on the motherboard, there might be some software level support for increasing the FSB. There won't be a way that I am aware of to adjust the CPU multiplier.
I've had some success in the past with using such programs like CPUFSB.
Just food for thought.

https://www.majorgeeks.com/files/details/cpufsb.html

cpufsb does indeed support W83194R-39 used by this board, gives you two options to try:
FSB 112MHz, PCI 37.33(CPU/3)
FSB 133MHz, PCI 33.25(CPU/4)

BUT board manual shows BIOS has support for both FSB and Voltage settings:
"CPU Internal Core Speed
If you set this item to Manual, two new items will appear: CPU Host BUS
Frequency ...
CPU Core Voltage
This item can be used to a set a core voltage for different kinds of processors.
Leave this item at the default value and your system will automatically assign the
correct voltage."
so I would start there

PIck up a coppermine 1133/133 with a Slot1 adapter and run it at 850/100, or maybe a bit more if you can get the FSB over 100. Much easier to find.

I ran a 1000/133 at 840/112 using the same method on a 100FSB mainboard.

Are you sure about that? I don't see a single one on ebay. Every 1133 that I see listed is a Tualatin.

I don't think any of the top speed Coppermine chips are common at all.

You are right the 1133 are pretty much all tualatin, and only a few coppermine 1000. I guess the advice is outdated from 18 months ago when there was much more of them on ebay, I just went on there and bought a 1000 for $13.

There is one more alternative, though I am not certain of its availability to you.
A 1+ GHz Tualatin Celeron (100MHz bus) and a compatible slotket.
Should the BIOS fail to recognize the Tualatin core, it can be patched with the BIOS Patcher utility.

In my experience, there’s no need to patch it. Worst case scenario, during POST, the displayed CPU type & speed will be completely wrong, but other than that it will work perfectly (as long as the CPU or slotket have been modified to support Tualatin, of course).
I ran Tualatins on boards with unpatched BIOS versions from 1998.

I have PIII 900E and it is sufficient for all games up to about 2002. Not sure if they still sell. Few years ago I bought a few of them.
