Out of the attic: CMX1024-3200C2 and Abit AN8 SLI

[visual1ce]

Hi,

 

I've taken out some old parts for some overclocking fun. But before I can get to the fun part I'm trying to get my RAM running in DualDDR 128-bit mode at stock CPU/NF4/DDR400 CL2 timings.

 

Here are the details of this particular system:

 

Coolermaster 460W PSU

ABit AN8 SLI Motherboard (BIOS 21 - Latest)

AMD Athlon X2 4200+ (Stock)

Scythe Mugen 2

TwinX2048-3200C2 (More info below)

ASUS EN8800GT

Seagate 80GB SATA HDD

 

OS: Vista x64

Drivers:

nForce 4 15.01 x64

Realtek Audio Driver x64 6.01.6305

nVidia GeForce Driver x64 190.62

 

Here are the details that appear on the RAM sticks:

 

CMX1024-3200C2 XMS3202v1.2

XMS3200 1024MB 400MHz CL2

 

Here are the settings I have set in BIOS:

 

DDR SDRAM Voltage: 2.75V

 

DDR400

CL: 2.0

Row Cycle Time: 11 (default)

Row Refresh Cycle Time: 13 (default)

RAS to CAS delay: 3 (default)

RAS to RAS delay: 2 (default)

Min RAS Active Time: 6

RAS Precharge Time: 3 (default)

Write Recovery Time: 3 (default)

Write to Read Delay: 2 (default)

Read to Write Delay: 4 (default)

DRAM Command Rate: Auto (default)

Burst Length: 4 beats (default)

Bank Interleaving: Enabled (default)

Read Preamble Value: Auto (default)

Max Async Latency Value: Auto (default)

DRAM Drive Strength: Normal Drive (default)

Bypass Max: 4 (default)

Idle Cycle Limit (IDL_Lmt): 16 cycles (default)

Dynamic Idle Cycle Count: Enabled (default)

MTRR Mapping Mode: Continuous (default)

32 bit DRAM Memory Hole: Auto (default)

 

USB Mouse and Keyboard Support have both been disabled, IEEE1394 controller disabled, CnQ disabled and ACPI set to S1.

 

The strange thing is, I've run Memtest 3.3 for like 12 hours with no problem but I cannot get through a 1 hour OCCT test. I did fiddle around a bit and I came within 10 minutes but I changed too many things... I think I'll try disabling bank interleaving and give it another go.

 

Also, I have a set of different RAM from a different vendor (2 x 512MB matched) which work without a problem (slower timings and lower voltage though) in the same setup.

 

If any of you guys can help me out I will appreciate it.

Hi,

 

Some more info:

 

So its the CPU:OCCT test I'm referring to which ineluctably returns with "An Error was Detected on Core1".

 

I have a 3800+ here in my attic as well... perhaps I should give it a try. It puzzles me though that the generic 2 x 512MB DDR400 RAM I have works passes through CPU: OCCT but not this RAM which I believe to be much better.

 

Also, I forgot the lot number on the RAM: 0618022-1. And just to confirm that these sticks are a matched pair. I don't see this batch number on the IC list for DDR-1 though...

 

In any case, I might install Vista x64 with a single stick and then try and get both sticks running in DualDDR mode after.

 

Any help or advice would be greatly appreciated.

 

Kind Regards,

Please set the Dim Voltage to 2.7X volts and then set the timings manually to the tested settings for the specific module you have, and then test the module/modules one at a time with http://www.memtest.org! If you still get errors, please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure.
