mfaridi Posted January 11, 2009 Share Posted January 11, 2009 yesterday morning I buy TWIN2X4096-6400. I have this RAM before ********, but this RAM was 2GB and I need 4GB of RAM , so I buy TWIN2X4096-6400. so first I unplug all power cable from my case and then I reset or clear CMOS or BIOS and install new CORSAIR RAM and press ON button my system start working , but after seconds I hear RAM failure beep and my system can not boot , so I change DIMM but nothing happen and still my system dose not work , I test DIMM 1 and 2 and 3 and 4 , but nothing happen , but when I use one RAM , I see my system boot and I can use FreeBSD and WIndows VISTA , only my system work with 2GB of RAM and dose not work with 4GB of RAM but I do not have this problem with ********, I put 1GB in DIMM1 AND 1GB in DIMM2 and work with CORSAIR I must use only one DIMM and 2GB of RAM I do not know what is problem I update my bios last Friday and it is new bios ******** are DDR2 800 please help me I solve this problem I hear many thing about quality of RAM made by Corsair. Please help me.:[pouts::[pouts: Link to comment Share on other sites More sharing options...
007bont Posted January 11, 2009 Share Posted January 11, 2009 insert just one ram module, then enter your bios and set the dram voltage to 2.1 volts. Also increase the nortbridge voltage with +/- 1.5 volt. Save and exit the bios. Shutdown the pc and insert the second module, if succesfull post cpu-z screenshots of the memory and cpu tab.

mfaridi Posted January 11, 2009 Author Share Posted January 11, 2009 I see this on package of RAM Twin2x4096-6400C4 but I see on each RAM this Twin2x2048-6400C5 So I think my RAM is this Twin2x2048-6400C5 Link to comment Share on other sites More sharing options...
007bont Posted January 11, 2009 Share Posted January 11, 2009 can you post a screenshot of cpu-z , memory and spd tab? does your system boot now with both modules? Link to comment Share on other sites More sharing options...
mfaridi Posted January 11, 2009 Author Share Posted January 11, 2009 can you post a screenshot of cpu-z , memory and spd tab? does your system boot now with both modules? No my system dose not boot with two module . I will test it with one modules and put in here CPUZ result Link to comment Share on other sites More sharing options...
007bont Posted January 11, 2009 Share Posted January 11, 2009 No my system dose not boot with two module . I will test it with one modules and put in here CPUZ result and you did made the bios changes? Link to comment Share on other sites More sharing options...
mfaridi Posted January 11, 2009 Author Share Posted January 11, 2009 and you did made the bios changes? no right now I will test it tonight but another question when I use CPUZ 1- before change bios and only with one module ?? 2-after change bios and use one modules ? 3- after change bios and use two modules ?

007bont Posted January 11, 2009 Share Posted January 11, 2009 First you load up setup defaults in your bios, then save and exit the bios. restrat the pc and re-enter the bios, changing the dram and northbridge voltage as mentioned in the previous post. Save and exit the bios and shutdown the pc. Insert the second module and then if the system boots, you can run cpu-z if the system does not boot with the 2 modules, you can use cpu-z on one module. Just to clarify, cpu-z will only help to identify the type of modules you are using! Link to comment Share on other sites More sharing options...

mfaridi Posted January 12, 2009 Author Share Posted January 12, 2009 I clear bios and try set DRAM voltage to 2.1 , but I can not see this voltage and maximum voltage is 1.95 my bios is like this picture I attach it so I have to use one modules and run computer and start use CPUZ I see these pictures I think my ram is Twin2x2048-6400C5 Link to comment Share on other sites More sharing options...
007bont Posted January 12, 2009 Share Posted January 12, 2009 Right, Set your dram voltage to 1.95 volt insert one module and test that module with Memtest. Test it in channel A1 and B1. Once finished do the same test with the second module. Disable usb legacy, before running memtest in the bios. please post the results you get from memtest!

I can not find good Camera for take photo and my Nokia 6230i do not take good photo so I write for everything you I see on my ram I see this cm2x2048-6400 c5 5-5-5-18 1.80v ver3.1 800mhz 2599211 08430040 2048MB xms2-6400 I wish this information can help us to solve problem I will get photo.

mfaridi Posted January 13, 2009 Author Share Posted January 13, 2009 I think there is no way for solve my problem . but I hear DHX models can work good for me with this motherboard , but I do not know what is real different between XMS2 and DHX ?

DerekT Posted January 13, 2009 Share Posted January 13, 2009 The XMS2 family is Corsair’s mainstream line of performance DDR2 memory. DHX is the form factor that contains the memory. The casing if you like. Download Memtest v2.11 from--->Hereand extract the ISO image. Burn the ISO image to an CD-ROM disk. Download CPU-z from Here . Perform a hard reset to clear any BIOS stack corruption issues.

mfaridi Posted January 15, 2009 Author Share Posted January 15, 2009 is it always the same ram module that doesn't work, or the same memory slot of your MB? I want send two modules for warranty. I think one of the modules has problem Link to comment Share on other sites More sharing options...
mfaridi Posted January 18, 2009 Author Share Posted January 18, 2009 I send two modules for warranty and they send me new RAM , one of the RAM has problem and they change it for me . I Clear bios and set it as default and put two modules and I see my system start normally and in bios I see I have 4 GB of RAM and everything is OK , and I go to Windows XP and see it work good and I do not test it in Windows Vista. I run CPUZ and everest I attach it for you Please see it and check is everything OK and my RAMs work good with high performance or NO ??? Do I set my RAM Dual Channel ?? I ask this question because my mainboard has four DIMM for install RAM , two of them are Yellow and two of them are Black I put two modules in Yellow Dimm , and I think CPUZ , show me they are Dual Channel . How I can use all power of RAMs and use them with High performance ? Thanks Guys again it is good day for me because I join to Corsair group of RAM Link to comment Share on other sites More sharing options...
