Ramguy.. we got a problem

Hi Ramguy

 

I refer to previous thread..

 

http://www.houseofhelp.com/v3/showthread.php?t=51765&highlight=itsme

 

After entering the new modules in my asus a7n8x I notice after a while that the system still did not run stable (SPD 5-2-2-2 @ 2.8v). So I removed de 3200XLpro from my asus and put them in my shuttle one at the time.

 

Running memtest on the shuttle SN25G2V2 (@2.6v) one module gave occasionally errors. The second module gave a lot more errors. Maybe 2.6v was not enough but my shuttle does not allow to change voltage.

 

So I moved the modules back to the Asus and ran memtest on each module one at a time at 5-2-2-2 @ 2.8v. Both gave errors in the first 5 passes but one more than the other.

 

So I changed setting to 6-3-3-3 @ 2.8v and also here... lots of errors in first pass (here I did not take the time anymore to test the modules seperately.)

 

Then I thought what if my Asus was bad... so I moved my XMS twinx 512 Mb (2*256) to the asus and ran memtest @ 2.6v (SPD setting) and no errors occured in 10 passes.

 

I would like to know what my options are. Yes, I could buy a new motherboard but then I would move to DDR2 of course...making the XLpros obsolete....

 

Looking forward to hear from you.

 

kind regards

Can you tell the CPU speed and it’s FSB as well? In addition, please tell me the bios settings you have set for both CPU and memory and any performance settings that you may have set?

 

Sorry for not giving you all the details.

 

mb ASUS a7n8x (non deluxe)

Radeon 9200 pro

ps 430 Watt Enermax

HDD Samsung 250 GB ATA

1 DVD RW

 

cpu Athlon xp 3200+ not overclocked

FSB 200 (auto)

DDR Voltage 2.8v (manual)

 

for test 1GB Twinx 2*512 @ 5-2-2-2 (part numbers 100314790 and 100314791)

settings : Optimal

memory: SPD

 

for test 1GB Twinx 2*512 6-3-3-3

settings : Optimal

memory: manual

 

In both scenarios errors occur within the first 3 loops of memtest86.

 

Last night I replaced the xlpro twinx 2*512 (5-2-2-2) with the xms twinx 2*256 (6-3-3-2) and the latter ran memtest @ 2.6v the whole night without errors.

 

Could it be a mb problem?

 

Looking forward to hear from you.

 

Kind regards

Please make sure that you have the latest bios and then install the modules in slots 2-3 and then load setup defaults and set these settings and test them again.

System Performance: User Define

CPU Freq: 200 MHz

Memory Frequency: 100%

Dim Voltage to 2.8 Volts

Resulting Frequency: 200 MHz

Memory timings: Manual

Would results in these settings

SDRAM CAS Latency: 2.0T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 2T

SDRAM Active to Precharge Delay (tRAS): 11T

Graphics Aperture Size is 128 MB

Amazing

With above mentioned setting the computer is running rock solid... not one error in memtest over the last 10 hours of testing.

 

How did you know? and how to get forward from here?

I have had to many of those MB's and we used it on our production line!

 

Does that imply that it won't be possible to have 5-2-2-2 on that board?

 

Does that mean I should consider buying a other mb? if yes,, which one?

 

Looking forward to hear from you.

 

Kind regards

You might try testing the modules one at a time to make sure its not one failing module.

 

Well, I mentioned in my first post that both modules were failing 5-2-2-2 @ 2.8v tested one at a time in the first memory slot of the A7n8x.

 

Do you want me to test them again one at the time but this time in the second memory slot?

 

Kind regards

Do both modules fail at those settings? If so that would suggest its not the memory!

 

yes, both fail... one in the first run and the other in the 5th or 6th run. Instead of buying a new mobo I'll keep the memory running @ 11-2-3-2.

 

Thank you again for your time.

 

Kind regards
