FranticLuca Posted February 6, 2009 Share Posted February 6, 2009 Goodmorning to all! I'm italian and my name is Luca. I'm the owner of one MB Biostar Geforce 6100am2 and all was good when I worked with 2GB of ram installed. Some days ago I decided to upgrade my computer adding 1 more modules CM2X1024-6400, but the computer just recognize the processor and freeze; so I bought one more module thinking tha MB needs pairs of ram, but the computer beeps every 2-3 seconds and nothing else (reading manual they said it means the MB doesn't see any memory). Maybe do I mistake in something? :confused: I hope someone can help me Thanks in advance Link to comment Share on other sites More sharing options...
Wired Posted February 6, 2009 Share Posted February 6, 2009 I don't see your motherboard listed on the Corsair Compatibility Site. Is the other memory the same part number? Link to comment Share on other sites More sharing options...
FranticLuca Posted February 6, 2009 Author Share Posted February 6, 2009 My MB support max 1GB every slot. I have four modules of 1GB, the same model for all. If i install one it works If i install two it works If i install 3 or 4 it doesn't work mmmmmm..... i don't see my MB in the compatibility list, too Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 6, 2009 Corsair Employees Share Posted February 6, 2009 What RAM did you have before you bought the Corsair? Are you mixing the new CorsairRAM with the old RAM? Will the 2 modules of Corsair RAM work by themselves? Link to comment Share on other sites More sharing options...
FranticLuca Posted February 6, 2009 Author Share Posted February 6, 2009 All 4 modules are the same from Corsair... two work good, when I install 3 or 4 it doesn't work at all... seems MB doesn't see any memory. I bought 2 modules 1 month ago and 2 3 days ago... Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 6, 2009 Corsair Employees Share Posted February 6, 2009 Please list ALL of the information from the stickers on the modules. Also, add your system specifications to your profile so that we can read them in the dropdown menu. Link to comment Share on other sites More sharing options...
DerekT Posted February 6, 2009 Share Posted February 6, 2009 Please look at your modules. Post the excact model and version number. ie. CM2X1024-6400C5 Version 1.xxxCM2X1024-6400C4 Version 2.xxx Link to comment Share on other sites More sharing options...
FranticLuca Posted February 6, 2009 Author Share Posted February 6, 2009 First of all thank you very much for your answers. I changed my technical profile adding my computer characteristics. Here I write all i can read on my CORSAIR Modules: Module 1 (I'm using it) : CM2X1024-6400 1.90V Ver7.5 3532645 09020858 5-5-5-18 800MHz 1024 MB XMS2-6400 Module 2 (I'm using it) : CM2X1024-6400 1.90V Ver7.3 3470290 08011226 5-5-5-18 800MHz 1024MB XMS2-6400 Module 3 : CM2X1024-6400 1.90V Ver7.3 1061772 08121162 5-5-5-12 800MHz 1024MB XMS2-6400 Module 4 : CM2X1024-6400 1.90V Ver5.1 3478422 08011253 5-5-5-18 800MHz 1024MB XMS2-6400 ...Tonight I tried to make many things, but all was without success... for example I took away bios lithium battery for some seconds, thaen I replaced it, I installed all four Corsair modules and bios saw and recognized them, but told me to set CPU frequency. I entered bios I tried to make to recognize CPU and again didn't want to accept my new 2 modules of ram... I go to sleep! :mad: Bye! (and sorry for my poor english...)

DerekT Posted February 6, 2009 Share Posted February 6, 2009 It's never advised to mix and match different versions and doubly so to do so in the same channel. You can drop your bandwidth down to 667Mhz and raise the NB voltage to 1.40v and see if that helps. Link to comment Share on other sites More sharing options...
FranticLuca Posted February 7, 2009 Author Share Posted February 7, 2009 mmm... ok... I understand, but why if I install 2 modules with different versions it works and it doesn't work with 3 or 4 modules? After I removed bios battery for some seconds, it sees all 4GB of memory, but asks me to set cpu frequency because there's a checksum error. Sure I can work with 2GB of memory, but now I want to know why it doesn't work... :laughing: Link to comment Share on other sites More sharing options...
DerekT Posted February 7, 2009 Share Posted February 7, 2009 It could well also be a motherboard memory controller issue. The board's memory controller might be wonky. If the DRAM tests out singly, then the modules are fine. They might not play well together, but as you have found, it might be a limitation of the memory controller. I think your only way out of this is to buy two GB modules if you want 4GB. That or an RMA of the board. Very likely if you install 4 X 2GB you will find the issue once again repeats.

FranticLuca Posted February 7, 2009 Author Share Posted February 7, 2009 hehehe... I can install max only 1GB per slot on this mainboard..:mad: ...btw right now I tried to install 3rd and 4th module and to remove bios' battery and all worked.... seems.... XP boot up normally, but Ubuntu has problems, freeze during booting and if it boots all after it reset. Now I have a system with 3GB (or 4GB) single channel. How do You think? If I ask retailer to change the module ver5.1 to one ver7.5 and i install 7.3+7.3 and 7.5+7.5 may it work? ....thank you very much for all your answers!!:biggrin: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 7, 2009 Corsair Employees Share Posted February 7, 2009 Did you try raising your memory controller voltage as Derek suggested? With 4 modules, you will typically need to raise your memory controller voltage to compensate for the increased load. If your retailer will assist you, I would suggest that you try to get 4 modules of the same revision. Link to comment Share on other sites More sharing options...
FranticLuca Posted February 8, 2009 Author Share Posted February 8, 2009 I tried all You said, but nothing. I was really depressed when I saw Ubuntu freezing... so I removed ram and left only 2 modules: all worked very good as before. I think the problem is not ram, but MB and I'm going to buy a new one. Anyway thank you all very much for the friendly help!! :)::)::): Bye and nice sunday! Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 8, 2009 Corsair Employees Share Posted February 8, 2009 Keep in mind that you will still mixing different revisions of memory which is never advised. A new MOBO may or may not resolve the issue. If your retailer will assist you, try to get all 4 modules of matching revisions. Link to comment Share on other sites More sharing options...
