BX chipset max cache accepted?

I read or heard some where that the BX chipset will only support up to 512 meg of cache? True or false?

The reason I am asking is that I just completed my second PIII modded BP6 running dual 1100E's (1100/256/100/1.75V) @ 110 FSB.

This board is at its' max potential and then some (all caps replaced, EC10 mod and VTT regulator mod as well as a few others).

The only way I can see getting more out of it is to install 1.4 PIII's and under-clock them. The only major advantages here are the larger cache size and the additional instruction sets but if the BX will only accept 512 then I don't want to waste my time and money on the 1.4's.

Does anyone have the answer to this question?

Regards,

This might be correct. I still haven't found any information on the BX but I do know that the ZX (BX's smaller sybling) only supports 256 megs of cache. I wouldn't be surprised if the roof was 512, which would still be pretty good considering the age of the chipset.

you could try too put some P3 with 512kB L2 and try it...but, as i remember BX was made for Xeon processors also, and they have 1MB L2!!!
so it's had to say...

In a couple Intel BX440 Designs docs, I found cache sizes of 128-KB and 256-KB (Celeron and Pentium-III, respectively). In another Intel BX440 Design doc, to discussed the cache size of 512-KB for a Pentium-II. So, maybe purrkur is right about a maximum size of 512-KB for the BX440.
