Hi there,

I just received today my memory modules. After installation, all seemed to be ok. But the first time i tried to launch a game, all was ok until 5 minutes playing, then got a blank blue screen and computer restarting. A friend suggested me to do a memtest, what i did, and i got one error :

 

Test : 8

Pass : 0

Failing address : 0001da7c094 474.7MB

Good : ffffffff

Bad : ffffff00

Err Bits : 000000ff

 

Is it really bad ?

 

Motherboard : Asus A7N8X-E Deluxe

CPU : Athlon XP 3000+ Barton

RAM : TWINX1024-3200PT

BIOS settings : Default except onboard AC97 disabled

Since i'm not technician, i hope it is that you asked for

Yes that is exactly what I asked for thank you! And please try this:

First move the modules to slots 2-3 if they are not there already and then move the FSB Jumper to pins 2-3 furthest away from the CPU. (I know that’s not what the manual says, but please try it.) Then before you turn the system back on clear the bios with the battery removed with the CLRTC jumper for about 2-3 Min. Then when you turn the system back on go to bios setup and load setup defaults and set these settings.

Then please test the system with http://www.memtest.org. This is what I had to do to get this MB to pass with any module I test with it.

Everything done, but got now 2 errors with the new memtest :

 

Test : 8 | Pass : 0 | Failing Address : 00012f80094 - 303.0MB | Good : ffffffff | Bad : ffffff00 | Err-Bits : 000000ff

 

Test : 8 | Pass : 0 | Failing Address : 00017b7a094 - 379.6MB | Good : ffffffff | Bad : ffffff00 | Err-Bits : 000000ff

Yes, I downloaded & burned & used the v1.50.

Module A is the one which was first on slot2, Module B was on slot3.

 

tests summary :

 

1. Removed Module B from slot3

 

2. Memtest (one pass) Module A on slot2

 

=> 1 error : test 8 | Pass 0 | address 000df0e354 - 223.8MB | Good/Bad is same as previous errors.

 

3. Moved Module A from slot2 to slot1

 

4. Memtest (one pass) Module A on slot1

=> No error !

 

5. Moved Module A from slot1 to slot3

 

6. Memtest (one pass) Module A on slot3

=> No error !

 

7. Removed Module A from slot3 & Added Module B to slot1

 

8. Memtest (one pass) Module B on slot1

=> 7 errors :

- test 8 | pass 0 | adress 0000f84a04c - 248.6MB | Good ffffffff | Bad ffff00ff

- test 8 | pass 0 | adress 0000fc4604c - 252.3MB | Good ffffffff | Bad ffff00ff

- test 8 | pass 0 | adress 0000009410c - 0.2MB | Good ffffffff | Bad ffffff00

- test 8 | pass 0 | adress 00000094114 - 0.2MB | Good ffffffff | Bad ffffff00

- test 8 | pass 0 | adress 0000af9e254 - 175.8MB | Good ffffffff | Bad ffff00ff

- test 8 | pass 0 | adress 0000de4a044 - 222.6MB | Good ffffffff | Bad ffff00ff

- test 8 | pass 0 | adress 0000f042044 - 240.1MB | Good ffffffff | Bad ffff00ff

 

9. Moved Module B from slot1 to slot2

 

10. Memtest (one pass) Module B on slot2

=> 15 errors :

All at test 8 pass 0. Most between 0.1MB & 0.4MB (like 10, didn't have time to note all), the rest between 170MB & 250MB. Err.Bits are all 10000000.

 

11. Moved Module B from slot2 to slot3

 

12. Memtest (one pass) Module B on slot3

=> No error (!)

 

After the result of step 12 remembering that you said failures in test 8 would suggest some other problem, i think that the problem does not come from the modules but from the slots. Can you confirme that ? If I move module A to slot1 and Module B to slot3, would the errors disappear ? I know if I do that, I will not have dual on, but my first interest is no more crash.

That would suggest some problem with the CPU or MB or PSU. If you have a bad module it will fail no matter what slots you have them in and usually on test 4. And I would make sure that you have the FSB jumper set to pins 2-3 and the modules should be in slots 2-3 as well. If that does not solve the problem, we can try replacing the modules if you like, but I would suspect some other issue from what you have posted.

Okay, I will not replace them at the moment. A friend suggested me doing tests on his own motherboard (a MSI 848P Neo-V) then if there is no error, this thread would be closed and i'll try to contact my motherboard reseller about its warranty and/or change the power unit. Thank you for all quick help :)

After many tests, all seems to be good. Modules are not incriminated. And...er... I'm really dumb. There was a mistake about the slots. You were right to remind me that modules should be in slots 2-3. All this time i believed that the slot2 was the blue middle one...I was wrong.

 

After the end of the tests (all successful) on my friend's motherboard, I read again my motherboard manual, then I saw that in fact slot2 is the black one (the nearest from the CPU). Yeah, laugh at me !

 

So now the modules are really in slots 2-3 and all is going well.

 

Thanks for help and all your patience !

aka Tart, who have to learn how to read a manual :D:
