Witam,
trochê manuala poczyta³em i czê¶ciowo problem siê rozwi±za³. P³yta obs³uguje max na jeden slot 256MB.

Pozostaje tylko kwestia pamiêci z ECC.

W manualu s± takie informacjê na temat RAMU:

The Mainboard provides four 168-pin DIMM sockets for system memory
expansion from 8MB to 512MB SDRAM, 1GB registered SDRAM or 1GB EDO
DRAM. (EDO DRAM is available for 66MHz processors only.)

Bank/DIMM Memory Module Total Memory
Bank0/DIMM1 8/16/32/64/128/256MB 8MB~256MB
Bank1/DIMM2 8/16/32/64/128/256MB 8MB~256MB
Bank2/DIMM3 8/16/32/64/128/256MB 8MB~256MB
Bank3/DIMM4 8/16/32/64/128/256MB 8MB~256MB
Total System Memory 8MB~1GB

DRAM type, size, parity supported:
* EDO DRAM: for 66MHz system frequency only
* Unbuffered, registered SDRAM with SPD
* Both parity or non-parity are available.
* 3.3V, Single/double-side, 8/16/32/64/128/256Mbytes
(Max. memory size: 256MB registered SDRAM or EDO DRAM)
* Both 4Mbx4 and 16Mbx4 (Each side has 16 chips.) SDRAM devices are
supported in the form of Registered DIMMs only.

ECC (Error Check and Correction)
This mainboard can support the ECC function while utilizing parity modules. To enable
this function, users must set “DRAM Data Integrity Mode” to “ECC” through “Chipset
Features Setup” from the BIOS setup screen. All in all, ECC’s function is to detect and
correct the errors of transfer data.


Nie wiem czy dobrze rozumujê, ale skoro wk³adam pamiêci ECC 512MB, slot ma ograniczenie na 256MB, a ko¶ci ECC s± traktowane jako sparowane czyli takie same i dzia³aj± co¶ na zasadzie dual channel wiêc sysytem widzi dwie ko¶ci 256MB jako jedn± 256MB. ?!? trochê zamiesza³em, ale staram siê to jako¶ zrozumieæ.

Pozdrawiam
