[QUOTE="Crazy_Eddy, post: 58895, member: 167"] Yep, the DFI Ultra-D board physically has 2 PCI-E slots just like the SLI version, so that helps tremendously. AnandTech had an article long back showing that nF4 Ultra Chipsets could be converted to the SLI version for any board (even an Asus A8N-E), just that you physically need 2 PCI-E slots to make use of SLI. Angry_Games from the DFI Support Forums had made a statement long back saying as per all the nF4 Ultra chipset inventory DFI had sent out - all could be modded to SLI. No idea about their current inventory, as nVidia was planning on re-designing the chips for the nF4 Ultra instead of merely modifying the SLI chipsets into nF4 ultra ones (much like disabling pipelines on graphics cards for lower end models). Drop a post at the DFI forums to know the current status of things. IIRC, there were some driver incompatibilities as well - nVidia absolutely did not like the idea of modding nF4 Ultra chips into SLI , and hence mucked around with the drivers to put road-blocks where they can. They even dis-allowed selling of SLI bridges with non-SLI boards (however current drivers do not need the bridges altogether) Both me and Darky used the [B]24-pin[/B] 400W Powersafe with good results. There is no 24-pin 500W model as yet, but a basic mod should allow you to convert a 20-pin model to a 24-pin. Cost ~ 1.4K, so pretty cheap too. This is the absolute cheapest you should go for, and still expect good results with it :) DFI makes it absolutely mandatory to use a 24-pin PSU, while most other 24pin boards get along with 20-pin PSU's. It would be wise to heed DFI's advice. AFAIK, the reason for dead RAM was the voltage regulator on the 5v line. It heats up tremendously when in operation (Sunny had put up pics of thermal scans of the DFI boards, those showed the hot spot as well) , and doesnt put out a steady voltage either - ultimately killing the RAM. When using RAM with the default 3.3v line, you'll be pretty fine. If switching to the 5v line for your mem, you would absolutely have to stay above 3.2V and the higher you go, the better the voltage quality is. [/QUOTE]
