I've inspected all CPU and mems pins, seems to be fine. Other thing, BIOS sets 1.60v and SPD is 1.50v. Are you relising new BIOS update for G41C ICH7 Chipset? Other thing, i've been _foruming_ and seems to be g41 problem (independent on brand) on 1333Mhz mems...

If you check the Memory QVL document for the G41C-GS, a memory speed of 1333 is an over clock:

The memory controller in your system is part of the G41 chipset. The specifications show a supported memory speed for DDR3 memory to be 1066 maximum:

So a DDR3 memory speed of 1333 is an OC on your board. Normally the more memory that is being used (4GB instead of 2GB for example), the harder it is to over clock the memory. Less memory is easier to OC, as you have seen.

Try these things to see if you can get all 4GB of your memory to run at 1333:

1. In the BIOS, in the OC Tweaker,  DRAM Timing Configuration screen, set all the memory timing options to Auto.

2. In the OC Tweaker screen, increase the DRAM Voltage to 1.65V.

Save and Exit the BIOS, boot into Windows, and check your memory speed.

If this works at 1333, then you can try to set the memory timings lower than what the Auto setting gives you, likely higher than 9 9 9 24.

If this does not work, try increasing the memory voltage to 1.70V, with the memory timings set to Auto again.

If that fails, you can either keep increasing the memory voltage, or just accept you can't OC 4GB of that memory.
