qdi excellent II motherboard....ram supported?

[strange_dragon]

even the online TH99 site doesn't help answer this somehow so I thought I'll try ask here anyhow...

is double side sdram supported in both slots or just the first one?

I've got a double sided azen stick in first slot now and was wondering about trying this spare kingston (which is double sided too, I wonder how come its got outlines for a middle-located chip on both sides) stick in the second slot to give it a lot more total ram.

thanks

(azen seem to be possible AAP1146 if thats what its # is, kingston clearly says its a KVR133X64C3)

Memory Configuration
The P6I440EX/MATX EXCELLENT II mainboard provides two 168 pin 3.3V unbuffered DIMM sockets to support a flexible memory size ranging from 8MB to 256MB for SDRAM or from 8MB to 512MB for EDO memory.
The following set of rules allow optimum configurations.
Rules for populating a 440EX memory array:
The DRAM Timing register, which provides the DRAM speed grade control for the entire memory array, must be programmed to use the timings of the slowest DRAMs installed.
Possible EDO DIMM memory sizes are 8MB, 16MB , 32MB, 64MB, 128MB, 256MB in each DIMM socket.
Possible SDRAM memory sizes are 8MB, 16MB , 32MB, 64MB, 128MB in each DIMMsocket.

you show only partial type numbers on both sticks, not possible to identify them. That Kingston stick is most likely 64mbit technology which means it will only show 1/4 of its true size in this board.

well thats what the kingston label says aside to that its ValueRAM .. so here's the # off the chips of it: Samsung K4S281632B-TC75

as for the azen one...it says 2365-TRAN on the label otherwise no further # at all...chips being NEC D4564841G5-A10B-9JF

edit: kuriaki that didn't help with how it takes SD and/or DD, thanks still

Shouldn't the i440LX/EX as well as i440BX/ZX support max 128MBit density memory sticks ?
That means 256MB max per stick, doublesided with 16 memory chips and 16x8 organisation).
AFAIR my i440LX board, Asus P2L97, did work with a 256MB stick; the EX is just an i440LX with only two memory slots supported.

Denniss: all 440LX/440EX boards I encounter can only handle 128MB maximum per stick. Chipset limit is 512MB which means you'd need 4 slots. I think that P2L97 uses a nifty trick to recognize the 256MB stick and I bet you can't use a second 256MB stick. You might try using a 128MB stick in the 3rd slot.

strange_dragon:
The Kingston stick should have a number after that: KVR133X64C3/128 or KVR133X64C3/256. How many chips are on this stick?

The chips on the Azen stick are 16mbit and PC-66, the total amount of memory is 2 x the number of chips it has. This one is compatible for sure.

[Denniss]

Hmmm - seems I ned to verify this with my P2L97 and GA-686LX, maybe I find my M715 and test some i430TX boards as well. Sadly I only have one i440BxX compatible 256MB stick So i have to fill other slots with 64 MB sticks. Or I have to open my father's comp and use the 16-chip 128MB sticks from there (64 MBit density).

Currently running primestable with all installed memory reported as working:

Gigabyte GA-686LX with i440LX chipset, P2-233; one MDT 256MB i440BX-compatible 16-chip PC-133 SDRAM, one Hyunday 8-chip 64MB PC-100 SDRAM, two i430VX compatible 16-chip 32MB PC-66 SDRAM

Seven out of eight memory rows are in use (three double-sided/rowed plus one single-sided/rowed memory stick)

Maybe I should try to fill all eight memory rows with three 16-chip 128MB sticks replacing the 64 and the two 32 MB sticks.

thought it was just a store label till I compared it with someone else's quick cam-taken photo of similar stick and so well here's another # if thats the one you had been refering to....

9902364-002.A01
558249

This is what is listed at Kingston. As you can see the number you gave is incomplete and the last few numbers are date codes, not type numbers.

KVR133X64C3/64 64MB 133MHz Non-ECC CL3 DIMM
KVR133X64C3/128 128MB 133MHz Non-ECC CL3 DIMM
KVR133X64C3/256 256MB 133MHz Non-ECC CL3 DIMM
KVR133X64C3/512 512MB 133MHz Non-ECC CL3 DIMM
KVR133X64C3/1G 1GB 133MHz Non-ECC CL3 DIMM

There is not a single 440EX or 440LX board listed for this series as being compatible.
