Huud,   That should be correct, as the voltages would self regulate..   Hope this helps.    
Hi, I have a Dell R620 with 18 DIMM Dual Rank DDR3 [ 8GB 2Rx4 PC3 10600R 1333MHz ] modules, totaling 144GB. How should the layout be, I have gone through [ Dell PowerEdge R620 Owner's Manual ] but it does not properly explain how to use 144GB DIMM with 2 processor. I understand its just a sample configuration but its quite confusing. Currently I have installed A1 to A9 and B1 to B9 but the system only detects up to 128GB. I'm unsure how to go about this. Thank You
