18 months of BSOD's with CMX6CX3M3A1600C9

I had my system setup for me last year may 2010.

I have had hundreds of BSOD's since then. I have had this RAM replaced already once.

I have convinced my vendor whom sold me the mother board to RMA said motherboard just before the 12 months warranty and am still getting BSOD's I have removed all devices and have even turned off my Marvell 9128 sata 3 controller and moved both sata 3 drives off to the Intel controller in the hope to stop the BSOD's.

At one stage for about 4 weeks I had my lan controller disappear and only come back when i removed all memory and turn on for 20 seconds then replace RAM and the lan controller comes back.

I have tried other forums that specialized in BSOD's and they said everything points to a memory fault.

I haven't run memtest in months and decided today to act on the matter.

Here are my results.

First off the start of the test and the type of RAM.

 

After 45 mins this...

 

After 2.30hrs this....

 

I am still running memtest as I write this thread and will let it run for another 3hrs to see what other faults occur.

Every time I set the memory to what specifications are recommended for this type of RAM I have had BSOD's.

Every time I have tried XMP I get BSOD's.

Can someone tell me a solution to this matter.

Did you make sure to check the voltages for your memory? The DRAM voltage should be 1.65 and you may need some memory controller voltge too. It should be called QPI or something similar depending on the MB BIOS. It needs to be set to a value between 1.35 and 1.45v. I would start with 1.35v first at test it that way. XMP should adjust that voltage but sometimes misses it.

Sorry, I have several QPI voltage switches.

I have included 3 picture of my MB voltage control. Can you tell me which QPI voltage to adjust from the pictures below, I have attached.

 

BTW all of the voltage adjustments are in equal increments like 1.64 - 1.66 ad so on. So when I adjust what you suggest it will either be 1.34, 1.36 etc for the QPI.

There are two QPI settings. One is QPI/Vtt Voltage and the other is QPI PLL.

Which one do I adjust.?

it will be the one marked QPI/Vtt. Raise that to 1.34 to start with and see if tha makes any difference for you.

 

LOL left the computer run over night and now for the week I am up to 50 BSOD's.

I had difficulty with what I could see as the proper voltage after I adjusted it in the CMOS/BIOS.

So I used the Gigabyte tool "easytune6" to adjust and observe the voltages.

Here is my voltage details.

Is this the correct settings. Can you see anything that is wrong with any of the other settings or is the settings correct to your liking?

Test ONE stick at a time in the same slot to see if it's a stick or slot issue.

 

I have did as you suggested and started testing one stick of RAM at a time.

 

The memory specs for my RAM are (CMX6GX3M3A1600C9c) 9-9-9-24-2T 1.65v.

@Wired, am I right in leaving these settings as is?

 

I have left the memory settings at these specs and am now testing the memory one by one.

How long and how many tests do I run it for? Sorry how many passes on each stick of RAM, I am coming up on the second pass with the first stick and memtest says "Pass Complete, no errors, press Esc to exit".

@Wired

Right I put in one stick of ram at a time and allowed memtest86+ ver4.20 to run for three passes (some 55mins each).

1. First stick No problems.

2. Second stick No problems.

3. Third stick and REPORTED ERROR!

 

I have taken photos of the results of each individual stick after 3 passes and labelled them and have attached to this reply below.

 

So what happens now that i have found an error in RAM stick 3?

I have re-slotted the two remaining sticks in on the MB.

Gone into the bios and set all the voltages at default.

Switched on the XMP profile to the specs 9-9-9-24 2T 1.65v and booted.

That was 2-3 hrs ago and the system is running smoothly without any BSOD's.

Thanks for your help.

If you don't mind could I ask this question.

I need this computer for work till Holidays as I is my work computer.

I can buy the same type of ram for $60.00 a kit.

http://www.mwave.com.au/sku-37140411-Corsair_XMS3_6GB_%283x_2GB%29_Memory_Kit_1600MHz_%28PC3_12800%29_DDR3_RAM_240_pin_DIMM_C

 

If I buy another kit this week then RMA the faulty kit. Can I still use that ram with the ram that I am suggesting to buy?

IE 2 kits of 3x2gb CMX6GX3M3A1600C9. In total 12 GB.

 

Can two kits of this memory run as compatible on my GA-X58A UDR3 MB.?

Just trying to cover my bases for work, Wired!:biggrin:

LOL, Today having priced the postal of this RAM back to Corsair under the RMA is more expensive than to go out and replace the product. By the time I spend time posting and wait possibly 10 days @$200 a day ($2000 lost in work down time) while the work computer is down, isn't viable for me. Its cheaper for me too go out an buy a new kit of ram and have it here now.

You can contact our customer service once you have the RMA# and ask for an advanced RMA. But I would suggest you install one module then go to BIOS setup and load setup defaults and enable XMP and test them one up with memtest.org. It sounds like you may not have done this when you tested them?

Hey RAMGUY, Thanks for the advice but that is what I did the same procedure on all ram sticks.

The funny thing is right, I bought this RAM last year 01/06/2010 $238. But today I got the same RAM but ver2 for $45. I can't believe the drop in price over a period of 12 months.

 

Anyway,:laughing: I am up and running, put the new ram in, reset the CMOS. Then set the ram to XMP and system defaults and I am typing to you right now with a stable system.

My Force 3 120GB SSD is showing through ATTO optimal performance, where as before I was getting dismal results. I am just happy the whole system is working properly.

 

I would still like to honour the RMA that Corsair has offered me.

Maybe with any luck I might get the same version of ram on the RMA as I have just bought.:biggrin:

You guys have been brilliant in your help.

 

I am just dirty I paid a computer shop money to diagnose the system and they never picked this problem up.

Thanks for your help RAM GUY.

I am impressed that Corsair will take a RMA on this matter so quickly. I have just gone out and bought the same RAM for $45 and I was given a mailing price to RMA said defective ram for $69. So in the future if its expensive ram and becomes faulty I will consider a RMA.

 

To bad Corsair hasn't got a place in Australia to deal with RMA's.
