Possible ram trouble.

[Gelleous]

I am having trouble with reboots and lost or corrupted files. In a new system I am using a Chaintech 9cjs mobo, intel p4 3.0 ghz non prescott cpu, twinx1024-3200xlpt ram, Antec true 480 psu, Nvidea 6800 GT, and Western Digital 160 HDD. I have updated the bios to the latest 7.0 and am running at all default settings. I called chaintech and they suggested I run 3Dmark03 in a loop to see what happens. On my inital try I couldn't get it to run, it kept telling me it found corrupted files. I downloaded it again and tried with the same results. I then removed one stick and tried them individually. One stick ran for 8 hrs straight before I stopped it and the other ran only about 10 minutes before the first corrupted file error then fewer minutes each time I restarted until it would not even begin the benchmark. I ran the memtest86 ver. 3.2 you recommend three times and on the stick in question I got 2 errors on test 3 each time and on test 4 I got 79, 81, and 84 errors respectively. All other tests showed 0. I have no idea what that means but I hope you do.

I see from the memtest screen my settings are RAM :202 mhz (DDR 404) / CAS : 2.5-2-2-5

The second stick of the pair showed no errors on any of the tests.

Please advise if there is something else you want me to try.

Thanks, John

Please try setting the Dim Voltage to 2.75 Volts and see of that does not solve the problem. And I would try and set the timings manually to the settings listed bellow.

Dim Voltage to 2.75 Volts

Resulting Frequency: 400MHz

SDRAM CAS Latency: 2T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 2T

SDRAM Active to Precharge Delay (tRAS): 5T

If you get no errors in memtest but the system is still not stable, I would maybe check them in another system to be sure if you can. And you might look at your PSU and make sure you have enough power for your configuration.

I tried to set the dimm voltage at 2.75 but the option seems unavailable. The default is 2.6 and my options are +.1, +.2, and +.3 I tried the voltage at 2.8 and it reduced the errors on test 4 to 3 errors on 1st pass, 0 errors on 2nd pass and 2 errors on 3rd pass. No errors on the other tests. At 2.7 voltage setting I got 1 error on test 3 in three passes and about 20 errors per pass on test 4 in each of 3 passes. The good stick checked errorless in 3 passes at the 2.8 setting.

I manually set the latency to 2-3-2-5 as you suggested for each test.

As for the psu what do you mean " look at it ". It is a 480 w psu more than enough power if it is working properly and if not how do I check it?

Thanks for responding I'll check back.

What is the make model of you MB?

Did you read my first post?? It's a Chaintech 9CJS Zenith. Please advise with any other ideas I might try. I don't know if a few errors are acceptable or not but since one of the sticks tested perfectly I assumed there was reason to believe they both should.

Well we can try replacing your modules if you like.

Please send us a email with a copy of the form or all of your info name address and phone# and the Module part# and copy the link to this post and email it to Warranty@corsairmemory.com. Or you can also use the On Line RMA Request Form as well.

If after 1 day or 24 hours excluding weekends you do not get the RMA please email the same to rma@corsairmemory.com and we will help to resolve it.
