TWIN2X4096-8500C5DF Memtest errors after BSOD


Recommended Posts

Hi there,

 

I recently upgraded my RAM from 2x TWIN2X2048-8500C5D Dominator modules to TWIN2X4096-8500C5DF. I have extensively tested each module separately and in different combinations with no errors in Memtest86+ v2.11.

 

My system however has become unstable with BSOD’s in WinXP SP3 of various errors usually occurring after the system has been on for at least a day. My system will then not boot and remain in a continuous BSOD cycle.

When I run Memtest straight after the BSOD I get 100s of errors after a few secs. If I hard reset/power the system and run Memtest I get no errors.

 

I have the latest BIOS version for my MB and I believe I have the correct memory settings. Here are my current Gigabyte EP35-DS3P memory settings.

 

MB Intelligent Tweaker (M.I.T.)

 

Robust Graphic Booster [Auto]

CPU Clock Ratio [ 9 X]

Fine CPU Clock Ratio + 0.0

CPU Frequency 3.00Ghz (333x9)

CPU Host Clock Control [Disabled]

Pci Express Frequency (mhz) [Auto]

CIA 2 [Disabled]

Performance Enhance [standard]

System Memory Multiplayer (SPD) [Auto]

Memory Frequency (mhz) 1066 1066

DRAM Timming Selectable (SPD) [Manual]

***Standard Timing Control***

CAS Latency Time 5 [5] I believe the initial number is what was auto detected by MB

DRAM Ras # to Cas # Delay 7 [5]

DRAM Ras # Precharge 7 [5]

Precharge Delay (tRAS) 24 [15]

 

***Advance Timming Control***

ACT to ACT Delay (tRRD) 4 [Auto]

Rank Write to read delay 4 [Auto]

Write to precharge delay 8 [Auto]

Refresh to ACT delay 68 [Auto]

Read to precharge delay 4 [Auto]

Static tRead value 6 [Auto]

Static tRead phase adjust 0 [Auto]

 

***System Voltage Optimized***

System voltage control [Manual]

DDR2 Overvoltage control [+0.30V]

PCI-E Overvoltage control [Normal]

FSB Overvoltage control [Normal]

(G)MCH Overvoltage control [Normal]

Loadline calibration [Auto]

CPU coltage control [Normal]

Normal CPU Vcore 1.22500 V

 

 

 

 

Any help would be greatly appreciated.

Please make sure that you have the latest BIOS version and the go to BIOS setup and load setup defaults (very Important you do this step) then set the tested settings of the modules:

***Advance Timming Control***

ACT to ACT Delay (tRRD) 4 [Auto] (This should be 5)

Rank Write to read delay 4 [Auto] (This should be 5)

Write to precharge delay 8 [Auto] (This should be 10 or 11)

Refresh to ACT delay 68 [Auto]

Hi,

 

I did have the latest BIOS but still I re-flashed my BIOS w/ ver. F6a loaded Optimized defaults. Set the MB settings to the settings that were suggested, reinstalled XP SP3 successfully. Then after a few hours I again received a BSOD and system was stuck in a BSOD loop. I tested the memory while system was in BSOD loop with Memtest, again 100’s of errors within a few seconds.

 

I hard powered down the system then powered it back up and XP SP3 booted without any problems. Ran Memtest again and only one error appeared after 1 pass. I then tested each module again in all four slots separately at least 2 passes each and no errors were found.

 

I have also noticed when testing individual modules that any placed in slot 3 or 4 are detected as DDR3 for some reason in Memtest.

 

Do you have any other suggestions which I could try?

I have changed the MB settings as suggested except for the ‘System Memory Multiplayer’ because I can’t seem to select 1066 manually. There is also no option to disable 'Performance Enhance' only Standard/Turbo/Extreme so I have left it as Standard

 

Performance Enhance [standard]

(G)MCH Overvoltage control [+.100]

Refresh to ACT delay 68 [72]

 

System Memory Multiplayer (SPD) [Auto]

Memory Frequency (mhz) 1066 1066

The options are as follows:

Auto

2.00

2.40

3.20

3.33

4.0+

2.50

3.00

4.0~

 

If I select 3.20 the memory frequency is displayed as 1066 and 1066 but when I save/reboot the system and enter the BIOS the frequency show as 800 and 1066.

Just an update to my problem, I have tried the settings as posted above.

Performance Enhance [standard]

(G)MCH Overvoltage control [+.100]

Refresh to ACT delay 68 [72]

 

The system seems to be running a bit more stable, it ran for over 48hrs then BSOD which is nearly twice as long as previously. I ran Memtest and again 100s of errors after a few seconds. I hard powered down the system and ran Memtest one error occurred after 2 passes which was what happen previously.

 

I again went through the process of testing each individual module and again no errors.

 

EDIT: The same problem occurred and the system was not even on for 24hrs.

 

 

Can you advise what the System Memory Multiplayer (SPD) should be?

I have posted what the options are in my previous post.

System Memory Multiplayer (SPD) [Auto]

Memory Frequency (mhz) 1066 1066

The options are as follows:

Auto

2.00

2.40

3.20

3.33

4.0+

2.50

3.00

4.0~

 

If I select 3.20 the memory frequency is displayed as 1066 and 1066 but when I save/reboot the system and enter the BIOS the frequency show as 800 and 1066.

 

 

If the correct option is 3.20 I assume the memory frequency should not be reported as running at 800 1066 in the BIOS after saving to BIOS and rebooting the system?

I have not seen that MB so I do not know what it should be, I do have another MB like this but I normally just change it till I get the right setting, just when you make changes the changes do not take effect until you restart. Sorry too many MB's to remember them all.

Just an update one of the memory modules is now producing errors when tested in Memtest.

 

Would it be possible to get my modules replaced?

If possible the Air Flow unit also needs to be replaced as it makes a whining noise when in operation.

 

Thanks again.
