Abit AV8 - correct settings for 4x256mb

Abit AV8 VIA K8T800 Pro

AMD 3200+

corsair twinX dual channel 3200

 

CPU-Z Memory Slot info:

 

Slot #1 CMX256-A-3200C2 Corsair

Slot #2 CMX256-A-3200C2 Corsair

Slot #3 CMX256-A-3200

Slot #4 CMX256-A-3200

 

I'd like to know the correct settings to getting this Mobo to see all 4 slots of the above memory please. Or any info. I've spent all day reading various message boards to no avail. I've tried some BIOS changes ( changing from 400 to 333, changing from 1T to 2T) and they haven't worked so I may not be reading the right information. I'm looking for a definitive answers (maybe my two sets are not compatible? but they were on my last P4 system) Thanks.

What exactly is the problem? It will not post with all 4 insalled or runs at DDR333?

 

Dim Voltage to + 2.8 Volts:

CAS Latency CL=3.0

Row Cycle Time tRC Bios Default

Row Refresh Cyc Time tRFC Bios Default

Ras# to CAS# delay tRCD 3

Row to Row delay Bios Default

Min Ras# Active Time tRAS 8

Row Precharge Time tRP 3

Write Recovery Time Bios Default

Write to Read delay Bios Default

Read to Write Delay Bios Default

Refresh Period tREF Bios Default

Enable 2T Timing Enabled

Then test the system with http://www.memtest.org and make sure it's stable!

Motherboard: A8V Deluxe

CPU: AMD 64 3200+

MY MEMORY: 4 sticks of 256mb PC4000 XMS

 

CPU-Z Memory Slot info:

 

Slot #1 CMX256-A-3200C2 Corsair - on compatability list

Slot #2 CMX256-A-3200C2 Corsair - on compatability list

 

Slot #3 CMX256-A-3200 - *not* on compatability list

Slot #4 CMX256-A-3200 - *not* on compatability list

 

ok, so the bottom 2 are no on the compatability list here:

http://compatible.corsairmemory.com/memorysearch.aspx?modelid=531#othermodules

 

But if i take out the " CMX256-A-3200C2 " and put the " CMX256-A-3200 " in their place the system runs fine. It just won't recognize all 4 modules even though CPUZ will detect them. Also, all 4 ran fine together on my former P4 system.

 

IS there a BIOS setting I'm missing or will these never be recognized on this motherboard :confused: ?
