Value Select pc3200


Recommended Posts



I just recently purchused the 1gb kit of Value Select ddr400 memory. One of the sticks gives errors if I run it on anything beyond 166mhz. By itself the module fails in test 4 of memtest86 v3.1 - in duel channel with both corsair modules, that same 1 chip fails once in test 7 of memtest. If I test it at 166 the failing module doesn't return any errors. Shouldn't a DDR400 chip be able to run at say for example 180mhz? The second module runs fine at 180. Just a bad stick?


board - a7n8x (@333mhz)


current settings for timings - 8,3,3, 2.5T


I think voltage is set to 2.7...


If anyone could make any suggestions please do.

Test them one at a time in a 200 Mhz FSB system. Testing them in the current system can pop up errors unrelated to the memory.


meh.. well that didn't work i tested in a 200mhz system and it still failed...


will just have RMA this kit then.

Please make sure that you have the latest BIOS for your MB and load Setup/Optimized default settings, and try the following BIOS settings;

VS1GBKIT400 or VS512MB400

CPU Freq: 166 MHz (333 FSB)

System Performance: User Define

Memory Frequency: 100%

Resulting Frequency: 166 MHz (333 FSB)

Memory Timing: User Define

SDRAM CAS Latency: 2.5T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 3T

SDRAM Active to Precharge Delay (tRAS): 8T

DDR Reference Voltage: 2.7 Volts

AGP Voltage: Default *unless you have ATI (9200 or 9600) or NVIDIA (5200 or 5700) then 1.6 Volts suggested!*

All other settings are motherboards defaults

Then please test them one at a time with http://www.memtest.org and let’s make sure it's not some other issue! I would run the test for at least 2-3 passes to be sure!
