Page 5-1 of the "AlphaPC 164SX Motherboard, Windows NT, User's Manual" says:
"Each bank consists of two DIMMs and must be fully populated."

Actually my 2nd Alpha was a PC164SX (the first was a Multia I fried).

NOPE. The PC164SX does not have L3 cache. That's why I bought a PWS to replace mine. From the "AlphaPC 164SX Motherboard" User's Manual:
L1 Icache 16KB, direct-mapped, instruction cache on the CPU chip L1 Dcache 8KB, direct-mapped, data cache on the CPU chip L2 backup cache Onboard 1MB, direct-mapped, synchronous SSRAM backup cache with 128-bit data path

They are in pair. Banks are two dimms wide...

Hmmm, maybe you had the 2MB version then? There are two versions I beleive...

Sweet when I can boot. My problem still persist. The bus gets reset twice and sometimes 3 times at the first initialization. When this happens, scsi polling fails and I can only see pka0.7 ... I really must know why...

Awh, this line is only the OEM_STRING environment variable of the SRM. It can be customized. Atom is the name of this server and Quanta is my company... ;)

I am only using the narrow interface.

The IDs of my scsi devices are 0,1,2 for hard disks, 4 for the Yamaha and 6 for the NEC-222 cdrom, 7 of course being the adapter. I didn't try this config in a PC tough but I'm pretty confident that it will work since I don't have problems once I get through the loader process (SRM + loader). FreeBSD has never failed resetting the bus. Only SRM and loader do. My 2940UW can be configured through AlphaBIOS. I just resetted the values to default...

Yes. A 2930u2 has an external narrow, internal narrow, and internal LVD connector. A 2940u2 has an external narrow, internal narrow, internal wide, and internal LVD connects. The only difference between a 2940u2 and 2940u2w is the external connector/bus.

WAIT! Cand you load your 2940 bus and test it for me? I really need to know if the card is faulty or not. The test is very simple: init, init, init, init etc 'till you type through your keyboard! ;) Seriously, if after 10 inits in a row, having a slow CDROM, CDRW and hard disks, you don't loose a single device, then I will consider changing the adapter (testing first with the 2940...) Will have to find one of those Qlogic 1040 ultra ...
Having more guts, I would have changed this SX machine for an UP1000 but I've had enough problems with this one...

99.999% sure.
