Need Help With ABIT KR7A-Raid and Memory Modules

Canon EF-S 17-55mm f/2.8 IS USM

I have a ABIT KR7A-Raid MB

2-512mb DDR PC2100 memory mods

Manual says to populate Dimm slots 1-4 in order:
Slots/Banks per the manual:

Dimm Slot 1 - bank 0/1 - Mod 1 512mb
Dimm Slot 2 - bank 2/3 - Mod 2 512mb
Dimm Slot 3 - bank 4/5
Dimm Slot 4 - bank 6/7

The manual says they can take up to 1gb per slot.

With the 2 modules in Dimm slots 1 and 2 (Sandra reports banks 0/2)they continue to crash under use.

If I use the mods seaparate they work fine!

The banks are 0/1 2/3 for DDR I understand.

Any ideas on what I'am missing here?

No hammering the ABIT please :) just want ideas

in that motherboard, all for dimm slots take ddr up to 1 gb in size, so 4 gig max.

abit are awsome, no need to hammer it! ;)

what brand are the sticks of RAM?

have you tried skipping DIMM2 and jumping to DIMM3
(not sure if that mobo will support that, but it won;t hurt it if it doesn't)
reason for trying this is dimm2 may be faulty.

lmk what you find out.

Dunno about the ABIT board, but my ASUS board requires to populate 1/3 first... then 2/4...

Another thing to check is the timing settings in BIOS. It may be that the MOBO just has too-aggressive settings as default.

The one I nought when I built the system is Micron.

What my son bought I do not know.

I can not find anything that tell sme if it is ECC or etc. Sandra does not give this info.

This is Sandra's data report:

Logical/Chipset 1 Memory Banks
Bank 0 : 512MB DDR-SDRAM 2.5-3-3-7CL 2CMD
Bank 2 : 512MB DDR-SDRAM 2.5-3-3-7CL 2CMD
Speed : 2x 133MHz (266MHz data rate)
Multiplier : 1/1x
Width : 64-bit

Memory Module(s)
Memory Module 1:
Micron 512MB 16x(64Mx4) DDR-SDRAM PC2100U-2533-750 (CL2.5 up to 133MHz) (CL2 up to 100MHz)

Memory Module 2:
512MB 16x(64Mx4) DDR-SDRAM PC2100U-2533-750 (CL2.5 up to 133MHz) (CL2 up to 100MHz)

They are identical except Micron and ? for the one he bought.

I will check that and see. The manual says to populate Dimm 1-4 in order?

I went through and tried the different settings in the Bios manual vs auto and etc. I will have to go through it again.

Strange, I think one is ECC and the other is Non-ECC I bet. Run fine separate, but together they crash?

Any software you know of that checks this for you?

Sandra does not give this data. Gives all the other info but.

I normally run Sandra myself, don't know of anything better...

Got it to work.

I put the unknown mod in slot one and the Micron is slot three and now it works?

Not per the manual but what the heck!

They are now running banks 0/4

slot 1 - bank 0/1 Unknown Mod
slot 2 - bank 2/3
slot 3 - bank 4/5 Micron Mod
slot 4 - bank 6/7

I changed the CMOS setting back to manual and 2-way interleaving but not sure if that was part of it or not?

Atleast now I can play Unreal Tourny! on the Net again!

I went back into the BIOS and set the Bank Interleave back to Auto (4-way Interleave) and it still works fine.

It must be running the new mod in slot one and the old mod in slot 3 that works?

go figure.

It's great to hear you guys talk dirty...Populate the motherboard, etc.. Sure beats the eternal whine about post-processing of photographs, and why this site is not "cool" because the average age is over 30 years.
Do keep it up - New Year's Eve is my birthday and I am a damn site older than 35, and it is a real pleasure to tune in on forums of you whiz-bang guys. Makes me think my youth was misspent.
HAPPY NEW YEAR to you!
