trouble: VS1GBKIT400 for Gigabyte's Mother Board

Hello.

 

I'm tired of taking care of my computer during the holidays.

 

I purchased VS1GBKIT400(2x VS512MB400) in October, 2004 at Newegg for my mother board 'Gigabyte GA-8PE667 Ultra 2.' I removed my old 256M DDR333 (very stable) and installed VS1GBKIT400 into DIMM slot 1 and 2.

The compatibility list by Corsair says VS1GBKIT400 is good for this mobo.

 

However, these two months after the installation, sometimes I see 'bluescreen' of Windows 2000. So I recently suspected DIMMs and checked with memtest86 3.1; I found that a lot of errors appeared every time.

 

I tried many combinations of CPU Clock and DIMM Freq again and again,

but even in the best case there are some errors per one pass of

memtest86. Even in the very normal settings (i.e., CPU at 2.4G,

DIMM at 333MHz), there are many errors.

 

Could you tell me what I should next? :[pouts:

 

Thanks,

iga_001

 

M/B: Gigabyte GA-8PE667 Ultra 2 (Version F3 - latest)

CPU: Intel Pentium 4 2.4B (SL6EF)

DIMM: VS512MB400 x2

HDD: ST380013AS x2 (RAID0)

DVD: Pioneer DVR-A06J

 

BIOS Settings that bring less errors:

CPU Clock Ratio: x18 (2.88GHz)

CPU Host Clock Control: Enable

CPU Host Freq: 160

Fixed PCI/AGP Freq: 33/66

Host/DRAM Clock Ratio: Auto [x2.5]

Memory Freq: 400

DIMM OverVoltage Control: +0.2V

AGP OverVoltage Control: Normal

CPU Voltage Control: Normal

 

At the Advanced BIOS Setting Menu,

I select 'SPD' as memory timing.

You will need to set the memory Freq at DDR333 with this platform. With the settings you have set you are trying to run the memory at DDR480 and that would be way above spec for the modules. The memory freq is a multiplier off of the CPU at with the memory at DDR400 with a default FSB of 133 that would make the multiple 4-6, so 160 FSB Divided by 4 X 6 = 480 MHz.

Thank you, Mr. RAMGuy.

 

Sorry but you've lost me. The POST message says the DIMM Freq is 400MHz with the settings I quoted (160MHz x2.5, CPU: 2.88GHz). If this correct, they didn't run at 480MHz.

And my old 256MB DIMM (not Corsair, PC2700) could run very stably at 340MHz (170MHz x2, CPU: 3.06GHz) for 1.5 years, which is the frequency the POST reports.

 

Anyway, I'll memtest again with the settings of DDR333 (DIMM Freq: 333MHz) with

1) CPU Host Freq: 133, Host DRAM Clock Ratio: 2.5 (CPU: 2.4GHz) and

2) CPU Host Freq: 166, Host DRAM Clock Ratio: 2.0 (CPU: 2.9GHz).

Is this correct?

 

Thanks,

Mr. RAMGuy,

 

I tried checking both settings with memtest86 3.1.

 

Anyway, I'll memtest again with the settings of DDR333 (DIMM Freq: 333MHz) with

1) CPU Host Freq: 133, Host DRAM Clock Ratio: 2.5 (CPU: 2.4GHz) and

2) CPU Host Freq: 166, Host DRAM Clock Ratio: 2.0 (CPU: 2.9GHz).

Is this correct?

About the case 2, memtest reported tons of errors.

About the case 1, there is no errors in 3 passes of memtest86. Looks good.

However, 2.4GHz is too slow for me because I used this P4 at 3.06GHz with old PC2700 DIMM.

Do you have any good idea about the better combination of DIMM/Freq settings?

Should I have bought PC2700 DIMM instead of PC3200 for OverClocking?

 

thanks,

 

PS. I set 'DRAM Refresh Mode Select' to 7.8us manually when memtest ran without errors. With 'by SPD', memtest86 reported a few errors in case 1.

I would suggest testing the modules on a system that is not over clocked and has a better bios translation, which would help verify the issue. And I have explained the memory frequency ratio; you might do some more research on the MB makers forum if they have one!

Thanks, RAMGuy,

 

Hmm...okay, I'll use this machine without OC. Much memory is better than OC. :laughing: But I have new quick questions.

 

1) I ran memtest all day long. Both memtest86(3.1) and memtest86+(1.40) report some errors at the same address (0x0002fb5d9c0, bit 0x00000200) about every 10 passes (@normal settings). Will this be a problem?

 

2) I think VS512MB400's SPD is 2.5-3-3-8, but I realized that this mobo cannot set TRas# to 8. CPU-Z (http://www.cpuid.org) says current memory timing is 2.5-3-3-7 even if I choose 'by SPD.' Is this memory module compatible with this mobo (GA-8PE667 Ultra 2)? Your site says VS512MB400 is compatible with this mobo...

This time, I checked only one stick with memtest86+. The condition is very normal. The result is 6 errors at the same address in 50 passes. I attached a screen shot. I don't think this is good.

 

Thanks,
