xms2700 gone bad

[stealthfx]

hi all, i recently upgraded my system, new motherboard, case ect..i ran everything at default, and started windows setup, thats when my prob started, it would get halfway, and id get errors, corrput files ect.. i removed the HD and put it in another pc, ran scandisk and checked it,it was fine, i removed the cpu and put it back in my old mobo, tested it , it was fine. I even looked at my win xp cd, not a single scratch or mark. I downloaded a copy of memtest, burned it to a cd, booted off it, and i found out that one of my stick of ram was bad, by the 8th pass it would give me all sorts of errors. Now i have 2 sticks of corsair xms2700, 256mb,cl2. They were purchased at diferent time ( i dont think that has any relevance). I tested them modules one at a time, and even switched ram slots, and it came back to the same stick that would generate errors after a bit. My pc is running like crap with only 256 mb right, please help.

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?

Processor

 

2.20 gigahertz AMD Athlon XP

128 kilobyte primary memory cache

512 kilobyte secondary memory cache

 

VIA Technologies, Inc. KM400A-8237

Board: KM400A-8237

Bus Clock: 199 megahertz

BIOS: Phoenix Technologies, LTD 6.00 PG 10/20/2004

 

Also, i went into my bios and went into the "DRAM Clock/driver control" tab

i copied down all the settings, they are as follows..

 

FSB freq = 200 mhz

Current DRAM freq = 166 mhz

DDR freq = 333mhz

Tming = Manual

Cas latency = 2

Bank interleave = Disabled

Precharge to active = 5T

Active to precharge = 7T

Active to cmd = 5T

DRAM burst length = 4

DRAM Queue depth = 4

DRAM command rate = 2T command

Write recovery time = 3T

tWTR = 2T

 

Ive been running the system at default bios settings since i built it...

 

Hope this is what you needed. Thanks.

Please use this as a reference, but make sure that you have the latest BIOS installed before making the necessary BIOS settings:

CMX256A or CMX512-2700C2

CPU Freq: 200 MHz

Memory Freq: 166 or 333

Dim Voltage: 2.7/2.75 Volts

DRAM Clock: 4:3/83%/166 or 333

DRAM Timing: Manual/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): 7T

Bank Interleave: 4 Banks/Enabled

SDRAM Burst Length: 4

SDRAM Command Rate: 1T

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

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!

ok, well, i didnt get to thank RAM guy for his help before, i upgraded my bios, and using the settings he\you posted as a reference i tweaked the bios settings for the RAM, the system ram w\o a glitch for almost 2 weeks. Then, the stick which was giving me trouble the last timebit the dust hard. I get memory errors while running windows, burning cd ect..futhermore, when i leave that stick in, and run mem test 86 or whatever, by the 5th pass it has generated over 3 thousand errors. The tech support given to me was able to prolong the life of the stick of ram by 2 weeks, but now its dead, pleeeease RMA this thing for me, ill post part # later when im at home. Running on a 256 instead of 512 is killing me! :!:
