There’s no multiplier on the board, only for clockspeed, which I left at 33mhz. Maybe that is the issue.

2.5x multiplier is hardlocked in podp you should correctly install jumpers on motherboard only

What else is there to do if the boards runs at 33Mhz? Isn’t that all?

Nope not all. Once more - you should find manual for your motherboard or info for jumpers settings for correct detection/installation PODP83 Pentium overdrive CPU.

Apologies for ressurecting the thread, but thought this question might be better answered here:

I recently acquired a podp5v83, and put it into my old childhood 486DX2 66Mhz-build, just to play what if… the board is from ‘93 and I have not been able to ID it, seems like it is a taiwanese clone board..anyway the system boots but the Overdrive is reported as a 486DX2 at boot, is this expected behaviour?

If the motherboard is from 1993 you will probably encounter many issues when trying to use a POD. Intel changed the Overdrive specs very late in the game, so pre-1995 boards usually don't work reliably (or at all) with the POD.

The other jumpers are for cache management. And also to select 5V, if applicable

The board is 5v only. I can’t find the specific board, I believe it is a clone board. It is very close to some of the Pine Technology boards, but not exactly.. so I do not have access to a manual. It is only equipped with jumpers for the clockrate.
I haven’t tried it much yet, just got it to boot.

But just wondering if it registering as a 486DX2 was expected from an old board like this.. or if I will damage it?

Its not so bad to begin with photo of your motherboard 😉

Here you go 😀

By the way, the manufacturer identifier says it’s a Lucky Star-board, however from layouts and searching countless hours, it more closely resembles a Pine Technologies board.

It's a common layout for many motherboards on UMC, Contaq, OPTI and maybe ALI chipsets. I took a quick look at TH99 hardware database and the only hope is cache layout and keyboard controller positions. Many jumpers are hardlocked (but all motherboards required special jumpers configuration for Pentium Overdrive).

Lucky Star

Hi if you still have it could you dump the BIOS ROM?
