Move from 2gb to 4gb of ram - Fail!

Recommended Posts

Hi guys,

 

I, rather rashly it seems, decided to go and buy another 2gb of ram. See my specs for current set up.

 

I thought it would be quite simple to double my ram to 4gig. All Corsair Dominator, of course:):.

 

The first set of twinCMX1024-8500C5D I had said 2.1V ver1.5.

The new set have 2.2V vers1.2 (why the diff in v?)

 

Question1 - Can these to sets work together (original set is in slots 1 & 3 - new set in slots 2 & 4)and yes, I have tested all slots and all modules through memtest - all aok. Why test, I hear you ask? See next Q.

 

Question 2 - Regardless of what I do, I can not get my system to boot with any config other than 1 (2gb) set in dual mode. I even went back to the vanilla settings in the BIOS, but no joy. At best, I would get a continual series of short beeps meaning that power was an issue. I swapped in a 850w pack and got the same results, so I don't think it's that.

 

Could it be somehow related to my 1gb of ddr5 mem on my gc causing some sort of mem limit, due to having Vista 32bit os?

 

Bottom line is: I can't seem to get my machine to run with 4 gigs of ram:[pouts:(I also tried 3 sticka - nada).

 

Soz for length/thx for help:):

Mixing 2 different revisions of modules is not recommended but it may work. You'll likely need to raise the memory controller voltage up 1-4 steps above the stock setting to be stable with 4 modules.

 

Since you have tested both kits individually, you may simply have a combination of board and memory that will not work together. Try a single module from each kit in the proper slots for dual channel to see if 2 modules will run together on this MOBO.

After you try RAM GUY's instruction and IF you find that one module of one version works with another module of the other version, then you can move to the below instructions.

 

Lower your memory speed to allow for the extra memory. As well, you have different version and voltage requirements for the memory. Very likely this memory will NOT play nice together but you can try.

Download Memtest86+ V2.11 from--->

and extract the ISO image. Burn the ISO image to an CD-ROM disk.

Download CPU-z from
.

Shut the system down. Insert a single stick of DRAM in Slot 1 (Closest to the CPU) and slot 3.Enter your BIOS. Load Setup Defaults. Save Setup Defaults. On the main BIOS screen press Ctrl + F1. You will see the screen flicker. Next select the MB Intelligent Tweaker option. On that screen you will see many additional settings that were not there before. Set to these values but be sure that the last value you set is the MCH Latch Value. Leave it on Auto until you set all other values. Then set the Latch to 333Mhz, save and exit:

Shut the system down. Boot to the Memtest CD with that single stick and allow for two full paasses. Shut the system down. Remove the first stick and insert it in slot two. Repeat memtest. Shut the system down. Remove the first stick and insert it into slot three and repeat memtest. Do the same for the last slot. You have now tested one stick and all four slots. Shut the system down and remove the first stick. Insert the second stick in slot one. Retest. Shut the system down and remove the second stick and insert the third stick in slot one. Repeat Memtest. Do the same with the last stick. You have now tested all four sticks.

 

Now test for the Dual Channel Mode function of the memory controller. Insert a stick in slot one and three and memtest. Remove the set and insert the second set in slot two and four and memtest.

 

Results?

 

Finally, insert a stick in slot one and slot three, a stick in slot two and slot four and repeat Memtest. If Stable enter Windows and post screenshots of CPU-z's CPU, Memory and SPD tabs.
