Intel DG45ID and 4 * 1 GB Corsair DDR2 RAM

[Arun]

I have an assembled PC with Intel DG45ID mobo and 4 * 1 GB Corsair CM2X1024-6400 (1.90V ver 7.3) RAM. I am experiencing occasional Blue Screen issues and I believe it is related to the RAM. I think I was able to isolate the issue with one RAM module and when I use Windows without that RAM module then I haven't seen Blue Screen error. It has been only 2 weeks since I assembled the PC. I had already updated my BIOS firmware to the latest version earlier. Is anyone else using the same configuration and having the same problem? Is it compatible? Since it was able to run for several hours without any problem, I'm not sure if it is a compatibility issue? Can anyone help me with troubleshooting it before I submit the warranty claim? I am from India, will there be a local address where I can send the RAM for warranty claim?

The only memory Corsair supports in a four DRAM slot population is their Quad kits. This does not mean they will not work, just that you have no recourse to RMA Corsair if they do not work. If there are problems with the DRAM modules, they are still supported via lifetime warranty, but that is for physical defects ie. errors in a two stick kit mode. Matched Quad sets are highly binned modules for a four slot population. The Dual sets are tested as a kit, not a Quad and warranted as a dual kit, not a Quad setup. You need to Memtest them as Kits (2 modules, not as a four DRAM slot population). If they fail as a kit or singly, then you have RMA.

 

You are advised to drop the bandwidth to 667Mhz and raise the Northbridge +.2v. I don't know if your mainboard has an MCH voltage setting in your BIOS. If it does, set +.2v higher.

There is a limitation of the On Motherboard (Intel) memory controller or On CPU (AMD, Intel i7) and a population of all four banks at the full speed of a two bank run. This limitation is across the board with both AMD and Intel chipset based boards, DDR, DDR2 and DDR3.

 

Keep in mind that often issues can arise in the longer term even though you have shorter term stability. The issues seldom damage the DRAM unless you raise the DRAM voltage too high. They damage the on CPU (AMD) memory controller which has a harder time keeping up with the demands of a four DRAM slot population being run as fast as a two DRAM slot population.

.

Insert a single stick of DRAM in your board. Enter BIOS and set the DRAM to 667Mhz and the MCH voltage +.2v. Shut the system down, insert the other three sticks and boot to the memtest CD allowing for two full passes. If you pass, enter Windows and post a screenshot of your CPU-z CPU, Memory and SPD tabs. Please post all four of the SPD tabs, one for each module.
