Quad2X4096-6400C5DHX and a ASUS P5N32-E SLI

Hi guys

 

I bought a new homebrew system including an ASUS P5N32-E SLI and 4Gb (4x1Gb) CorsairTwinX XMS2, DDR2 PC2-6400 (800), 240 Pins, Non-ECC Unbuffered, CAS 5-5-5-18, EPP RAM.

 

On getting the motherboard I made sure that its firmware was upgraded to the latest version (1103). I also due to a known issue with Vista installed the OS with only 2GB of RAM, patched the system and installed the extra 2GB. But I am having stability problems with Vista 64 Ultimate. After much checking with many different systems diagnostic tools it appears that I am either having motherboard issues or RAM issues.

 

This problem manifests it's self in the OS either by not starting correctly, the computer hanging or just rebooting.

 

I completed a very methodical check of the RAM and slots

 

Memory Timings set to Auto

1) First by checking each of the RAM modules in every slots - no problem with any slot or module

2) All modules populating all slots - Microtopology failure on all modules

 

Memory Timings to to 5,5,5,18 2T (note: after reading some posts on this forum from Ram Guy I did remember to load default BIOS before setting these timings)

1) First by checking each of the RAM modules in every slots - no problem with any slot or module

2) All modules populating all slots - Microtopology failure on all modules

3) Then I checked combinations of modules and slots.

Slot A1 and A2 - First passed, second failed

Slot A1 and A2 (Memory swapped round) - First passed, second failed

Slot A1 and B1 - First passed, second failed

Slot A1 and B1 (Memory swapped round) - First passed, second failed

etc etc always the same problem, and I tried this will all sticks.

 

This is a curious issue, as each module shows as passed by itself, but combining them causes errors, this can be in different test though. When there are 2 modules it often fails on either the Inversion tree or Progressive inversion. On occasion chaotic addressing and Block rotation.

 

Any advice would be much appreciated.

Full System Spec available here.

 

Many thanks in advance

Hi RAM GUY

 

Thanks for the response... PSU a bit small... ok :S (me goes and runs off to see if I can RMA it).

 

Unfortunately I can not test is any of my friends systems as none have upgraded to systems that use DDR2.

 

Any other ideas or memory timings (and voltage) settings you can recommend?

 

Cheers

Just spoke to the supplier I got the motherboard, RAM etc etc from.

 

They advised to set the memory timings to 5-5-5-15 with the clock set to 1, and to set the latency to 667, then the voltage to 2.1

 

I've done this and am running some memory tests.

I'm running more memory tests at the moment using MemTest86+

 

 

The errors were all software based not BIOS based.

 

The software errors were:

The system hanging

BDOD's included NTDLL.DLL corruption, NTFS.dll corruption, Hard Errors, the usual less_than_or_equal stop

Failed boots (screen would just stay black before login)

System rebooting

 

Initally some of these issue's were due to drivers (nvidia mostly) but after letting MS update install the drivers that side of the system appeared stable.

 

Memory Test so far:

 

Test 1 (Individual stick)

Stick 1

Slot A1 X Passed

Slot A2 X Passed

Slot B1 X Passed

Slot B2 X Passed

 

Stick 2

Slot A1 X Passed

Slot A2 X Passed

Slot B1 X Passed

Slot B2 X Passed

 

Stick 3

Slot A1 X Passed

Slot A2 X Passed

Slot B1 X Passed

Slot B2 X Passed

 

Stick 4

Slot A1 X Passed

Slot A2 X Passed

Slot B1 X Passed

Slot B2 X Passed

 

 

Test 2 (2 sticks in different slots)

 

Stick 1 Stick 1 Status Stick 2 Stick 2 Status

Slot A1 Passed Slot A2 Failed

Slot A1 Passed Slot B1 Failed

Slot A1 Passed Slot B2 Failed

 

Stick 1 Stick 1 Status Stick 2 Stick 2 Status

Slot A2 Failed Slot A1 Passed

Slot A2 Passed Slot B1 Failed

Slot A2 Passed Slot B2 Failed

 

Stick 1 Stick 1 Status Stick 2 Stick 2 Status

Slot B1 Failed Slot A1 Passed

Slot B1 Failed Slot A2 Passed

Slot B1 Passed Slot B2 Failed

 

Stick 1 Stick 1 Status Stick 2 Stick 2 Status

Slot B2 Failed Slot A1 Passed

Slot B2 Failed Slot A2 Passed

Slot B2 Failed Slot B1 Passed

 

 

Stick 2 Stick 2 Status Stick 3 Stick 3 Status

Slot A1 Passed Slot A2 Failed

Slot A1 Passed Slot B1 Failed

Slot A1 Passed Slot B2 Failed

 

Stick 2 Stick 2 Status Stick 3 Stick 3 Status

Slot A2 Failed Slot A1 Passed

Slot A2 Passed Slot B1 Failed

Slot A2 Passed Slot B2 Failed

 

(I stopped at this point as the results appeared conclusive, and didn't move on to 3 sticks)

 

Test 3 (All four sticks - this was actually the first one I completed)

All four sticks failed a test

 

As I said at the top, I'm running MemTest86+ now as you've recommended this in previous thread... I'll let you know what the out come is.

i have the exact same problem!

 

Abit Aw9d MAX

Q6600 - G0

Same RAM

Vista Ultimate X64

 

I changed the voltage to 2.1v and the tRFC to 42 and its a little bit more stable. anyone know if the voltage is ok and the tRFC? alos because of the memory voltage should i use my dominator fan?
