Problem - GA-EP45-DS3L with F2-6400CL5D-4GBPQ

[al64new]

The problem is that my system freezes frequently. The key components are:

MB - Gigabyte GA-EP45-DS3L with F10 BIOS
Processor - Intel Core 2 Duo E8500 at 3.16 GHz
Video Card - EVGA 512-P3-N954-TR GeForce 9500 GT 512 MB
Memory - G.Skill F2-6400CL5D-4GBPQ

I have performed the following test using Memtest86+ V2.1

All tests were run with the CPU running at the standard speed (3.16 GHz) and all advanced memory timing settings were auto.

First Test:
Dual channel configuration (slots 1and 3)
Memory Settings:
Performance Enhance - Standard
Memory Frequency - 800
Time Control - 5-5-5-15
Memory Voltage 1.8v

Result - system freeze within 1 minute

Second Test:
Dual channel configuration (slots 1and 3)
Memory Settings:
Performance Enhance - Standard
Memory Frequency - 800
Time Control - 5-5-5-15
Memory Voltage 1.9v

Result - system freeze within 1 minute

Third and Forth Tests:
Moved memory to memory slots 2 and 4
Same memory settings as tests 1 and 2

Results - system freeze within 1 minute

Tests Five and Six:
Removed one memory module
Same memory settings as tests 1 and 2

Results - system freeze at 1 to 4 minutes into test

Test Seven and Eight:
Switched the memory modules and inserted the "new" module into a different memory slot
Same memory settings as tests 1 and 2

Results - system freeze at 1 to 4 minutes into test

Test Nine and Ten:
Tested each memory module individually in different memory slots
Memory Settings:
Performance Enhance - Standard
Memory Frequency - 667
Time Control - 5-5-5-15
Memory Voltage 1.8v

Results - both memory modules completed one pass of memtest86+ with no errors and the test was still proceeding fine when I stopped the test execution at 1+ hours into the test.

Test Eleven:
Dual Channel operation
Memory Settings:
Performance Enhance - Standard
Memory Frequency - 667
Time Control - 5-5-5-15
Memory Voltage 1.8v

Results - system freeze at ~5 minutes into the test

Test Twelve:
Dual Channel operation
Memory Settings:
Performance Enhance - Standard
Memory Frequency - 667
Time Control - 5-5-5-15
Memory Voltage 1.9v

Results - system freeze at ~5 minutes into the test

Test Thirteen:
Single channel operation - both memory modules installed
Memory Settings:
Performance Enhance - Standard
Memory Frequency - 667
Time Control - 5-5-5-15
Memory Voltage 1.8v

Results - system freeze at ~23 minutes into the test

Any suggestions or comments? Do you believe the memory is bad?

Thanks.

do you have other memory to try out?
it's weird that one can run DDR2 800, but freeze when running DDR2 667
or you could replace another pair with your local reseller to try first
thanks

I am not sure if I incorrectly stated the results of the tests I ran or not. However, I will summarize:

All tests at 800 MHz failed (both modules installed, only one module installed, and I have since executed tests with the memory voltage increased up to 2.05 - still failed).

All tests with both memory modules installed at 667 MHz failed (dual channel, single channel, 1.8 to 2.05 volts)

The only successful test was with a single memory module installed at 667 MHz at 1.8 volts.

sorry, we misunderstanding the result
we thought it would pass DDR2 800 while installing only one stick
if it can onlt pass DDR2 667 in single channel, please replace a new kit with your local reseller and try again
thanks

What about using RMA to get a new kit to try?

[G.SKILL]

of course it's fine to RMA with us
we'd recommend you to replacewith your local reseller because it should be more convenient
but if you would like to RMA with us, it's also fine
thanks
