I have one of these boards coming (a revision 1.22), as well as a AMD X5-133/P75+ ADW.

The board apparently has 256kb of cache installed already via four 64kbit x8 srams, and according to stason.org, it supports up to 512kb using four 128kbit x8 pieces. However, the board has 8 sockets which can be utilised in an alternate 256kb configuration (eight 32kbit x8 srams).

Has anyone tested whether eight 128kbit x8 chips work to give 1024kb? It seems a popular board, so I'm guessing someone here may have tried this.

On the PVI-486SP3 only half of the cache RAM sockets are 32-pin, the other half are 28-pin, so it isn't possible to insert eight 128k8 chips.

I tried to upgrade my board to 512k once by inserting 4x 128k8 chips, but it didn't work (cache wasn't detected by the BIOS). I blamed it on my cache chips, since I don't have another board to test them.

If anyone has a PVI-486SP3 running successfully with 512k cache, please report here with a SST screenshot. 😉

Ah, I hadn't anticipated that!

Oh well, I'll try and pick up a set of four 128k8 chips and see if I can get the 512kb cache configuration to work when all the parts arrive.
