stookza Posted February 16, 2013 Share Posted February 16, 2013 4 months ago i bought CMZ24GX3M6A1600C9 24gb corsair memories kit from seller in ebay, but i have 1 problem with 1 memory stick, the serial number on the sticker of this stick is different than the others and when i put this memory together with all the other sticks it always decreases 4gb, so i tried all combinations and nothing works. this stick works just alone as 4g, the system actually never detected all the 24gb so i was working always with 20giga of ram just with 5 sticks, and when i put all the 6 together it detected always 16gb on the bios, the bios is flashed and updated, and so i sent DFI a letter and they said that the board must detect all the 24g. so i was advised with 2 computers technicians and they said that this memory caused the problem because it doesn't belong to the set and that's why it doesn't work with the other sticks. I sent a letter to the seller earlier ["nhts" which looks very reliable seller] ,and still waiting for respond, someone has an advice for me? do u think that this can be the reason? do u think that can i send the whole kit back to usa and can he replace it to another kit with the same serial numbers for all the sticks?

peanutz94 Posted February 16, 2013 Share Posted February 16, 2013 Well, serial numbers may not always be sequential because of the way they are tested and packaged. Could you provide a pic of all the sticks? Was this a brand new kit or a used kit? Link to comment Share on other sites More sharing options...
stookza Posted February 16, 2013 Author Share Posted February 16, 2013 Thx peanutz A brand new, the serial number for all the sticks was in sequence of 0336xx, but only this stick has the number 033777.[i need to photo it to show u]. Link to comment Share on other sites More sharing options...
Synthohol Posted February 16, 2013 Share Posted February 16, 2013 compare the SPDs with CPU-Z. if they all match you should be fine. Link to comment Share on other sites More sharing options...
stookza Posted February 16, 2013 Author Share Posted February 16, 2013 Yes i forgot to mention i did it and the funny thing is that there is 1 with a different serial number in CPUZ but he is working good together with the all others and detected by the bios, and not like this 1 with the different number on the sticker.

Synthohol Posted February 16, 2013 Share Posted February 16, 2013 its possible that during testing, the next sequential stick had errors and was not sold. they tried other sticks from the same batch, if it tested good with the rest it was packaged and that would explain it.

stookza Posted February 16, 2013 Author Share Posted February 16, 2013 Thx I c. so do u think he should replace the whole kit for me? i patched a picture of CPUZ SPDS to show u the other stick with the different serial number on CPUZ that works with all the rest located in SLOT4. But this 1 with the different serial on the sticker doesnt work with them and i pulled him out. http://postimage.org/image/ux4jtu4mp/full/ Link to comment Share on other sites More sharing options...
peanutz94 Posted February 17, 2013 Share Posted February 17, 2013 so i was advised with 2 computers technicians and they said that this memory caused the problem because it doesn't belong to the set and that's why it doesn't work with the other sticks. I'm raising the:bsflag: on that one! Like we both said ,serial numbers are not always sequential. Part number is far more important than the SN. It shows it indeed came from that kit. I have two out of my six that are different as well, but haven't had any issues and came out of a sealed box. With the X58 chipset there are a lot of things that can cause memory mis-detection. Anything thing from incorrect settings in the BIOS to bent pins in the CPU socket and also your CPU cooler if it is not tightened down evenly could cause these symptoms. Before you go replacing the kit there are a few things to try right off the bat. 1) Are you using the XMP profile? If not please enable it and see if that changes anything. Also with XMP enabled you might have to set the DIMM or memory voltage to 1.6 or even 1.65v with that kit with that chipset. I know they are 1.5v sticks but that chipset generally needs the extra voltage Set this first making sure the QPI voltage is set to 1.35v and retest. If this fails move to step two! 2) What is the QPI (memory controller) voltage set to? It should be about 1.35v and if it is already there, you can try setting it to 1.4 and up to 1.45v without worry. Adjust and retest.I'm betting it will be this setting because of the increased load on the memory controller the last stick is putting on it. 3) do you get the same results no matter what stick you place in what slot? If all that fails then you need to test the memory one stick at a time in the first slot with memtest to be sure you don't have a bad module after all. Make sure you load set-up or optimized defaults before testing each stick and boot to memtest letting each stick run for about three passes or until you get an error.

stookza Posted February 17, 2013 Author Share Posted February 17, 2013 Hi again peanuts and thx for the reply. Those technicians i talked too just suspected after i told them about it, they were not sure 100% about the exception sn memory that is causing the problem. 1.I dont have any XMP profile or such an option in the bios! i was working on 1.65V DIMM memory all the time and for the last 4 months, till 1 week ago i changed it to 1.5V because i had 3 BSOD, every month had 1 bsod, related to memory dumps or caused by creative driver issues [Creative Technology Ltd DRIVER_IRQL_NOT_LESS_OR_EQUAL ha20x22k.sys] so i uninstalled the x-fi titanium driver + dsweeper and dcp and removed all related creative things in the registry, and after reinstalled the driver with the creative PAX driver of Robert Mclelland. 2.I dont know about the QPI voltage because i dont have any option of that in the bios too. maybe the name is different on DFI award bios? Sorry but i didnt understand, what did you mean "[memory controller]"? plz tell me, do i have any jumper or something on the board which i should change, or u meant just for a setting in the bios? 3.No i dont "get the same results no matter which memory i put on which slot". that memory with the different sn on the sticker always decreases 4g no matter what i tried, when he works together with the others, no matter on which combination and which slot i put him, but alone he works well as 4g stick. this is very strange... I tried all combinations and testings with "mwmd", "goldmemory" and "memtest"[8 tests in a row during 1 night with memtest] believe me. and the results were always fine on all the memories, when i tested them all together and also separated 1 by 1. I cant load setup or optimized defaults in the bios and test the memories after it, because if i do that the memories will work just on 1066mhz speed by defualt. It means i can do that but i dont wanna work on 1066mhz memory speed, and btw i tried it before few times and all memories tests were ok too, but the bios still didnt detect all the 24g. Maybe the problem is with the buggy board of DFI? or maybe with the bios? I really dont know what to do and what to suspect anymore. Link to comment Share on other sites More sharing options...
peanutz94 Posted February 17, 2013 Share Posted February 17, 2013 2.I dont know about the QPI voltage because i dont have any option of that in the bios too. maybe the name is different on DFI award bios?Give me time to download the manual and I'll see if i can find it for you. But since the memory is all testing out fine I have my suspicions its your MB that is having the issue. I cant load setup or optimized defaults in the bios and test the memories after it, because if i do that the memories will work just on 1066mhz speed by defualt. It means i can do that but i dont wanna work on 1066mhz memory speed, and btw i tried it before few times and all memories tests were ok too, but the bios still didnt detect all the 24g. It really wouldn't matter. If memory is going to fail it will fail at any speed and not just the rated speed. But at any rate give me 10 mins and I'll have an answer for you on the QPI voltage...

peanutz94 Posted February 17, 2013 Share Posted February 17, 2013 Okay on your board QPI would be CPU VTT voltage. I would make sure that is getting set to 1.35v and retest plz. @ Turbo DFI quit making enthusiast MB's over two years ago. So there is no BIOS updates for that board.

stookza Posted February 17, 2013 Author Share Posted February 17, 2013 I dont have 1.35v option, i have just 1.34 and 1.36, anyway i tried both of them but it didnt work either, still bios detects just 16gb with that specific memory and without it 20. Yes i asked them 3 months ago if they have "something special" for the bios, but they told me that there is no any update since the last 1 on the site.

Synthohol Posted February 17, 2013 Share Posted February 17, 2013 so just to clarify, if you start with the odd stick, boot up it shows 4G. then if you add a second stick it still shows only 4G? Link to comment Share on other sites More sharing options...
stookza Posted February 17, 2013 Author Share Posted February 17, 2013 No it shows 8 but when i cross the 12g, it starts to decrease 4g or just been not detected, and without it all the others are detected in the bios as 20g with no problems.

NP, it was worth a shot.

At this point it's really pointing towards that MB having some sort of issue with 24gig's ,which is entirely possible. It very well could be the CPU cooler or bent pin in the CPU socket. So i would go ahead and remove your cooler and CPU to check the socket for ANY bent pins in there. You may have to look with a magnifying glass since they are hard to see sometimes. If all looks good then remount the CPU and cooler making sure the cooler gets tightened evenly. And if you by any chance are using a large air cooler you should make the two upper most screws tight first to prevent the cooler from making the processor "sag" in the socket. Or at least that it is tighter than the others to prevent that sagginng. If the cooler sags enough and pull down on the CPU sometimes the pins don't contact the CPU enough and can cause all kinds of weird memory issues. And of course if that STILL fails then go ahead and have the kit replaced. But I just dont think thats going to solve your problems either. I really believe it's just the MB. I love my x58 RIG. They were just notorious for memory issues though. I'm on my third replacement board for this system and after three of them I finally got one that has been rock solid stable with 24gigs and overclocks real nice too!. But it was alot of frustration. As a matter of fact if you ask synthohol(at least i hope he remembers) that very issue is what brought me to the forums in the first place.:cool: Link to comment Share on other sites More sharing options...
stookza Posted February 18, 2013 Author Share Posted February 18, 2013 Thx alot for the detailed respond Peanutz! I followed your instructions and did it and reseat the cpu during the night and it was actually such an "ants work"! because i had to pull out all the wires and hardware and the mobo too just to dismantle the cpu because u cant do that from the other side of the case because its blocked! Anyway i wanted to do that long time ago and put new thermal grease cream on the cpu, and yes there was actually a bint pin on the socket that was crooked a little bit and i made him straight with tweezers. I built it all again and tried but still unfortunately, the bios doesnt detect that specific memory with all the others togteher and thats why there is no 24giga of memory so the problem remained :_{. Im so confused now i really dont know what to think about and how to fix it, I just think to replace the memory to anothers with the exact serials on the stickers and on cpuz, [why they dont precise and package it in the corsair factory or whatever it was packaged with the same sn to not create such a mess after?! i really expect from such a pro and quality company like corsair to do so] Or to get rid off and replace the damn DFI motherboard because since i have this mb, i had nothing but troubles and BSODS with it, actually i didnt want to buy it from the beginning[february 2009] and i wanted to buy an ASUS, and if u look at my system specifications too, u will c that all the others products are excellent and i had no problems with them, but the seller recommended it for me and said that this an "excellent performance mobo" ,and i started to regret it like even few days after since many problems began because this mb is too complicated and buggy. And now i dont know what to do first, if to pay the delivery fee and ship the kit to netherlands and replace them, but i need to get authorization first [like the seller said he would "apply for RMA with corsair"], or to ger rid of the dfi mb after 4 years and buy a new mobo of asus and spend more money and the devil knows.. maybe the problems with the memory remains...

I'm just not convinced it will solve your proble,s. As far as the SN goes, thats has nothing to do with the issue. Modules are issued a SN and then tested and packaged. So that is why they may not be sequential. It has absolutely nothing to do with your issue. I'm certain it's the MB, but i would go ahead and have your supplier replace them just so you can say you exhausted all possibilities. If I were you I would do the RMA yourself and save a lot of time so you don't have to wait on your supplier. Link to comment Share on other sites More sharing options...
stookza Posted February 18, 2013 Author Share Posted February 18, 2013 Penautz Believe me that believe u 100%! But i remember that u said yourself in this thread: http://forum.corsair.com/forums/showthread.php?t=105757 that "Even two sets of the same exact part number, version number, and so on is not suggested as synthohol stated" So forgive me, but i started to suspect since than day on every small detail that can cause a problem and unstable system. u said that part number is "far more important" than the sn but how can i know what is the sn and what is the pn? there is the 6 numbers on the middle of the sticker[033777] and 9 numbers in the right side of the sticker[123707782] and the internal serial number that cpuz detects which is different at all, so how can i know what is what and what is most important?

Correct mixing two SETS. Like if i you had used two 12 gig kits to make up your 24 gigs. The part number is CMZ24GX3M6A1600C9. When you received your memory was the package shrink wrapped?

Hi stookza Motherboard DFI Lanparty DK x58 T3eH6 and Processor Intel i7 920@3.40 ghz is not the best choice for OC as no XMP profile. Not support from DFI for this board so no bios update.

Can u tell me plz how can i do an RMA myself? i went to that page http://www.corsair.com/en/support/warranty but i dont know what to do exactly. and how many time do u think that it can saves if ill do the RMA myself and not by the seller?

So it always about take more risks and spend more and more money. Link to comment Share on other sites More sharing options...
