Any answers for this?


Recommended Posts

Well...

 

I let my old problem thread die as my box has been running stable. However, I am still stumped as to how/why I cannot run my ram at 1T. I did for about 3 months (under volted at 2.6v due to inexperience :O ) without any problems. Then after three months the sh** hit the fan and I experienced a month of problems. Also, even though it is stable now (my box is running 24/7 without a problem), memtest always gives errors on test #5. Running each stick on it's own produces no errors so I cannot say that one of the sticks is faulty. What gives?!?!?

Here are my current stable settings:

 


Genie BIOS Settings:



FSB Bus Frequency.............................  -  200

LDT/FSB Frequency Ratio.......................  -  Auto 

CPU/FSB Frequency Ratio.......................  - Auto 

PCI eXpress Frequency.........................  -  100Mhz 



CPU VID StartUp Value.........................  -  StartUp 



CPU VID Control...............................  -  Auto 

CPU VID Special Control.......................  -  Auto

LDT Voltage Control...........................  -  1.20v  

Chip Set Voltage Control......................  -  1.50v 

DRAM Voltage Control..........................  -  2.80v 





DRAM Configuration Settings: Memory ORANGE Slots.



DRAM Frequency Set............................  -  200=RAM/FSB:01/01

Command Per Clock (CPC).......................  -  Disabled

CAS Latency Control (Tcl).....................  -  2.0 

RAS# to CAS# delay (Trcd).....................  -  2.0 

Min RAS# active time (Tras)...................  -  06 

Row precharge time (Trp)......................  -  02 

Row Cycle time (Trc)..........................  -  07 

Row refresh cyc time (Trfc)...................  -  Auto 

Row to Row delay (Trrd).......................  -  02 

Write recovery time (Twr).....................  -  02 

Write to Read delay (Twtr)....................  -  02

The only difference between these settings and the settings that ran for 3 months before the crashing began were:

 


DRAM Voltage Control..........................  -  2.60v 

Command Per Clock (CPC).......................  -  Auto (Enabled)

DRAM Bank Interleave..........................  -  Enabled

Oops...didn't see the pretty picture :)

 

I understand that not everyone can get 1T to go, it's that I already had it going and that it will no longer go. I guess what I'm looking for is an explanation as to how/why this could happen. This is what's making me crazy at the moment (ya ya...so I'm a little obsessive...).

Try updateing the bios. I'm sure I read somewhere that there was a version of memtest on one of the bios's that didn't understand the memory controller properly on the newer A64's, version 1.5 I think. The newer bioses have 1.6 I believe. Apparently the old version would often show errors on test 5 even if the ram was working perfectly.

I searched for the memtest problem on the board and was unable to find anything. Do you have a link (I don't want to update my bios for no reason)? I also found some ram settings for my ballistix (1T etc) to try out and they allowed me to pass test 5 in memtest but booting into XP always gave a "STOP" error until I switched back to 2T. While I do appreciate the input here, I am really just looking for a straight answer to my original question...what would cause the system/ram to no longer run with the 1T setting after it had already run that way for 3 months before?

lowboy:

I tried the trc and trfc settings and they don't mess up anything. I was able to run memtest test 5 without error (1T - CPC enabled). However, when I boot to XP I still get the STOP error. Disabling CPC (2T) corrects this. I will run the rightmark memory analyzer later when I get home from work. I also have the MS memory diagnostic which I will try as well.

 

dow:

I remebered that I have the latest memtest bootdisk, so I will try that later.

I dont know if this is any help to you but when my pc sudenly goes on the blink I usely do what my russion friend does. Takes a run up at the case and boot it as hard as you can. That usely does the trick for me. Not all the time but most of the time.
