Bad RAM?


Recommended Posts

Please set the Dim Voltage to 2.7X volts (+.2 Volts W/Giga-Byte) and then set the timings manually to the tested settings for the specific module you have, XMS2700C2 Cass 2-3-3-6 for example or if you have Value Select "BY SPD" and then test the module/'s one at a time with www.memtest.org! If you still get errors, please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure.

I set the +0.2V option.

But I couldn't find the timing settings you mentioned anywhere. :(


So, I started Memtest again with both modules plugged in. And there were errors again. After about 9 minutes the error-list on the screen disappeared and "p:)" appeared. And then memtest froze (nothing moves and it doesn't respond at all).


Here's a picture of what I see right now:

I don't have a chance for that. Got no other computer which can accept these modules.


However, I just replaced the mainboard a few months ago, because I thought it caused the random crashes. I didn't know about memtest back then.


Plus, why does only one of the two modules have these memtest errors?

Can you tell me the make and model of MB you have along with 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?

Mainboard: Gigabyte GA-8IPE1000-G.

CPU: Intel Pentium 4, 3.0 GHz (running at 3014 MHz - I don't think I can change it to 3000 in the BIOS).


I'll post the BIOS settings after rebooting.


Edit: Here they are.


Advanced BIOS Features:

- CPU Hyper-Threading: Enabled


Frequency/Voltage Control:

- CPU Host Clock Control: Disabled

- CPU Host Frequency(Mhz): 100 (grayed out)

- AGP/PCI/SRC Fixed: 66/33/100 (grayed out)

- Memory Frequency For: Auto (can be changed to 1.33, 1.66 and 2.0)

- Memory Frequency(Mhz): 400

- AGP/PCI/SRC Frequenncy(Mhz): 66/33/100

- DIMM OverVoltage Control: +0.2V (can be changed to Normal and +0.1V)

- AGP OverVoltage Control: Normal (can be changed to +0.1V, +0.2V and +0.3V)

- CPU OverVoltage Control: Normal (can be changed to +5.0%, +7.5% and +10.0%)


That's all I found about Memory and CPU in the BIOS. I heard there is a hidden code to enable more "expert" settings. Is that right?


Edit 2: I got the hidden settings.


Advanced Chipset Features:

- Configure DRAM Timing: Manual

- CAS Latency Time: 2

- Active to Precharge Delay: 8

- DRAM RAS# to CAS# Delay: 3

- DRAM RAS# Precharge: 3

- Refresh Mode Select: 7.8 us

- Delayed Transaction: Enabled

- PSB Parking: Disabled

- Command per Clock: Auto

- Current CPC: Disabled (grayed out)

- Fast Chip Select: Auto

- Current FCS: Disabled (grayed out)

- Dynamic Paging mode: Auto

- Current Dynamic Paging: Disabled (grayed out)

- M.I.B.: Auto
