XMS 512Mb PC3200 gone bad??


Recommended Posts

well the other day i was doing my normal web desing work (i manage my site and a couple other sites) so i had open PhotoshopCS, Macromedia FireworksMX, Macromedia DreamweaverMX, and then my ftp program, i also had winamp and AIM open, and Windowblinds 4 running the background, this is my normal day for like 6 hours then i will reduce to just internet and winamp and aim and those things.


well i was sittin there rendering some projects when my screen flickered about 12 times then the whole pc shut down. i try to turn it back on and it gets a to the login screen then fails, then i try again it doesnt make it to the login screen at all and fails on the DMI Pool screen, so i think i have gotten a boot sector virus, i reformatt both my 160gig WesternDigital and 40 gig WesternDigital HDDs and try to reinstall windows, it wont reinstall it will get to the installation sequence then has many errors due to files not being able to be uploaded. so i take out the 40 gig drive and put it back into my old tower (pre built hp pavillion from 7 years ago) and i run the system restore disk, and it reinstalls the 98se os and all the oem software from the manufacturer, then i run the windows xp pro cd, and it updates to that, and works fine, so i have excluded the HDD from being the problem at this point.


i put the 40 gig HDD back into the new tower that i built and i try to run it and i get the NTLDR missing error (bad memory is usually the cause of this). so i run three different memory tester and each one fails after testing about 1mb of RAM, and then freezes at about 45% of testing. so i am pretty sure the RAM has gone bad, i have loaded the fail-safe BIOS for the mobo and then loaded the optimized settings like it said to do on the mo/bo manufacturers support forum.


i tried it again and still got the NTLDR missing error, so i am convinced that the RAM is the broken link in this situation. My specs are:


3.2 Ghz Pentium 4 Prescott, abit Is7-E2 mo/bo. nvidia 5700le optima agp 128mb video card corsair XMS 512MB PC3200 400Mhz RAM


any help on the situation?


EDIT: i forgot to say that i just built this PC right before Xmas, so it isnt even a month and a half old

uh it is only one module, i tested it with three different memory testers and they all failed.


the settings were the default settings for the mobo, i know the ram voltage was 2.6


the exact numbers from the ram stick are


CMX512-32002 XMS3202v5.1



XMS3200 512MB 400MHz CL2

Please make sure that you install the memory modules on either slots 1&3 or 2&4 and also have the latest BIOS installed for your MB; load Setup/optimized default settings, and try the following BIOS settings;

TwinX1024 or TwinX512-3200C2

Softmenu Setup

CPU Freq: 200

DRAM Clock: 400 MHz

CPU/Memory ratio: 1:1

Memory or Dim Reference voltage: 2.75 Volts

System performance: AUTO

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


Configure Dram timing by SPD: Disabled/User define

SDRAM CAS Latency: 2T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 3T

SDRAM Active to Precharge Delay (tRAS): 6T

Game Accelerator Mode: Auto

All other settings should be set to default settings!

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!

well i went out and bought a new stick of Kingston PC4000 512mb hyperx ram, and i put that in and the computer works like a charm again, tried to put the corsair stick in the 2nd slot and it just gave me a ton of erros whenever i tried to do anything in windows, so i am conviced that the ram is crap as of now, ill be sending it in for a new stick and hopefully have no problems after this

We will be happy to replace the module, but you may not be able to mix our module with another part# on this MB.

Please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it!

thanks for all the help, i just filled out my RMA form online and hopefully get an answer back by monday night


another quick question, do you think i will have problems running the replacement corsair with a module of Kingston HyperX 512MB PC4000 400Mhz??? cuz that is what i bought to replace the corsair, and i want to run both because they are both great RAM, and then i can run dual channeled in my system

I dont think you will be able to mix their modules and ours.

And you should get a reply by this afternoon, if not I would follow the link in my signature, "If you have submitted the RMA using the on line form and have not got a reply!"
