bios dos't allow mor then 512 ram

[Rehbar]

i have Acorp 6A815EPD motheboard. It have max 3 ram slot and menual allow max 512 ram in all slots of system system. This mean that you can not increas ram more then 512MB . Weather you use a single 512MB or (128+128+256=>512, 256+256=>512). If i used three 512MB ram in three slots bios dos't identify other two rams. It show and work only 512MB ram. How can i remove limits of 512MB to 3GB Ram..?

from the iNTEL i82815EP datasheet:

32 MB to 512 MB using 16Mb/64Mb/128Mb/256Mb
technology

512MB is the memory that this chipset can handle at max. this is a hardware limit and can not be expanded by bios updates or anything else.

but intel 810e and intel815 support max 2gb ram. so y not it support too?

[cp]

any proof that the chipset supports 2GB RAM despite what intel wrote in their datasheets? if you want i can quote from the original intel datasheets again or point you to their document server so that you can read for yourself. the i815 supports a max. of 512MB SDRAM as already stated.

i815 support 512max, this is a limitation built-in by Intel as they wanted to support their new Pentium 4 systems.
i810 supports 512MB max,too; at least 256MB max per Slot with i440BX compatible modules.

[Rehbar]

yes i agree but if we modify bios and remove the limitation of ram then will it support? Or intel815e chipset dos't control more than 512mb ram?

It also indicate that it dos't support Windows Vista too.... It is bad for intel chipset motherboards. And a chance to VIA leadform intel chipset boards.
It is bad and much bad for me bc i have intel chipset board...

[Denniss]

That's a hardware limitation, there's no way to have the memory controller support more than this.

hmm..that's what i wrote in my first post. and i prooved it by quoting from the Intel datasheet. maybe there's something wrong with my posts?!

Thanks you all

but intel 810e and intel815 support max 2gb ram. so y not it support too?

the entire 81x series supports 512MB maximum
