juris_doctor Posted September 27, 2007 Share Posted September 27, 2007 Holy cow! This is unbelievable! I hope someone can weigh in with some valuable insight on this one... :confused: Summary: 0) Have known stable system already with a pair of TWIN2X2048-6400C4 in slots #1 and #3. (This is the EPP memory that runs 4-4-4-12 at 2.1V) Want to increase system memory from 2GB to 4GB, so... 1) Ordered/paid for new TWIN2X2048-6400C4 kit from Nxxegg. 2) Installed kit, ran Memtest86+ v1.70 -> lots of errors! 3) Rma'd kit back to Nxxegg for replacement requiring add'l payment for return shipping costs. :(: 4) Received replacement kit from Nxxegg. 5) Installed replacement kit, ran Memtest86+ v1.70 -> no errors! Yay! Now I can load some operating systems and test the system. Okay... so far, so good... everything seems fine... Now start up CPU-Z v1.41 to check things out. Click on "SPD" tab and the following discrepancies are observed: Slot #1/Slot #3: Max Bandwidth PC2-6400 (400 MHz) Part Number CM2X1024-6400C4 SPD Ext. EPP Week/Year 23/06 JEDEC#1 270 MHz, 4.0, 4, 4, 13, 15, , 1.8V JEDEC#2 400 MHz, 5.0, 5, 5, 18, 22, , 1.8V EPP#1 400 MHz, 4.0, 4, 4, 12, 22, 2T, 2.1V Slot #2/Slot #4: Max Bandwidth PC2-5300 (333 MHz) Part Number VS1GB667D2 SPD Ext. (blank) Week/Year (blank) (blank) 200 MHz, 3.0, 3, 3, 9, 11, (?), 1.8V (blank) 266 MHz, 4.0, 4, 4, 12, 15, (?), 1.8V (blank) 333 MHz, 5.0, 5, 5, 15, 19, (?), 1.8V Uh-oh... What is going on here? How in the world did I pay for TWIN2X2048-6400C4 and end up getting VS1GB667D2? How did I end up with slower memory (333 MHz) than I paid for (400MHz)? How did I end up with lower quality memory (ValueSelect) than I paid for (XMS2)? :eek: Also, it's running at 2.1V which is higher than the 1.8V it's rated for which is probably not good. :bigeyes: This is extremely disappointing. After all the hassle, delays, and additional cost from the first RMA and now I have do it all over again. More hassle, more fiddling with the system, more waiting, more $$$$... :(: RAM_GUY: What kind of incredible bad luck is this? Do you have any idea what has happened here? Can you please help me get this straightened out? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 27, 2007 Corsair Employees Share Posted September 27, 2007 Are the modules that are detected as VS1GB667D2 running at 4-4-4-12, 800MHz at 2.1 volts? If so, then the SPD may have been programmed incorrectly, meaning the SPD for a VS1GB667D2 was programmed onto a 6400C4. There is no way that a VS1GB667D2 would operate at 800MHz at 4-4-4-12. Either way, if you would like to have them replaced, Please follow the link in my signature “I think I have a bad part! Or “Tech Support Express” and we will be happy to replace them or it! Please make sure you let them know you are from the forum! Link to comment Share on other sites More sharing options...
mariusart78 Posted October 2, 2007 Share Posted October 2, 2007 I recently bought a TWIN2X2048-6400C4 and one of the module is detected by CPU-Z as VS1GB800D2 in SPD. Is it another case of error in programming? The computer runs fine, i haven't overclocked the memory yet but i plan to increase the voltage to 2.1V and set latencies as in specifications to 4-4-4-12. Pls tell me what to do. Thanks Link to comment Share on other sites More sharing options...
juris_doctor Posted October 2, 2007 Author Share Posted October 2, 2007 And also this person, too: http://www.houseofhelp.com/forums/showthread.php?t=63114 Ramguy, thank you for your reply. My modules do seem to be able to handle 4-4-4-12 800MHz at 2.1V and the labeling/stickers on the heat spreaders are purple and say CM2X1024-6400C4. Do you really think the SPD simply got loaded with the wrong data? I never had this happen before; now it seems like happening to a lot of people? mariusart78, are you saying you bought a kit/pair and one module SPD is correct and the other says VS1GB800D2? Gosh, this sure seems strange to me... :bigeyes: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 2, 2007 Corsair Employees Share Posted October 2, 2007 If they are running at the specifications that the 6400C4 is tested at, then the SPD was probably just programmed incorrectly. Set the modules to 4-4-4-12 and make sure you increase the memory voltage to 2.1 volts. If either one of you would like to have them replaced, Please follow the link in my signature “I think I have a bad part! Or “Tech Support Express” and we will be happy to replace them or it!

Corsair Employees RAM GUY Posted October 2, 2007 Corsair Employees Share Posted October 2, 2007 Can you tell me the lot code of the modules? Should be a 6 or 7 digit number something like 0623047-10? Link to comment Share on other sites More sharing options...
mariusart78 Posted October 3, 2007 Share Posted October 3, 2007 Yes juris_doctor that's what i'm saying, one is reported correctly and one is reported as VS. Tried switching them and runnng them in single channel, still same thing. The lot code of my modules is 07330029-0. Ramguy thank you for your quick replies.

Corsair Employees RAM GUY Posted October 4, 2007 Corsair Employees Share Posted October 4, 2007 Ok thank you for letting me know, I have alerted the production manager and we are looking into the cause of this to prevent it from happening again. And I am sorry for the inconvenience. Please let me know if you have any more questions! Link to comment Share on other sites More sharing options...
juris_doctor Posted October 15, 2007 Author Share Posted October 15, 2007 mariusart78, thank you for your reply. RamGuy, I'm sorry I don't have lot numbers for you right now. I haven't had a chance to pop the lid off the box for a look inside yet. I wouldn't mind simply having them replaced as you offered and that is normally what I would do in a situation like this, but it's just too much hassle right now. I'm also thinking about the fact that it is set for 4-4-4-12 @ 2.1V and it does seem to be running okay. Maybe it really is just bad SPD data. As long as it performs, I'm not going to worry about it. I'm also thinking that one of the reasons I bought the Corsair memory in the first place is the lifetime warranty and that if I have any problems later on down the road, Corsair will be there to take care of it. RamGuy, does that sound like a good idea? I guess if there are problems down the road Corsair will take care of it, right? Thanks! Link to comment Share on other sites More sharing options...
