cvc009 Posted May 1, 2009 Share Posted May 1, 2009 Hey, I searched the forum for these settings and found one fairly similar, the only difference is that i have 8 gb and the other one 4 gb Can anybody telle what my BIOS settings should be? Thanks a lot Link to comment Share on other sites More sharing options...
DerekT Posted May 2, 2009 Share Posted May 2, 2009 The only memory Corsair supports in a four DRAM slot population is their Quad kits. This does not mean two dual kits or even worse two dual kits of different versions will not work together, just that you have no recourse to RMA Corsair if they do not work together. If there are problems with the DRAM modules, they are still supported via lifetime warranty, but that is for physical defects and 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. Keep in mind that there is no support for mixing and matching different versions of DRAM either since different version are of different fabrications and/or manufacturers. They might work, they might not work, but you have no support if they do not work. Thus you are advised to buy all the DRAM at the same time and in this way be more assured of getting the same versions. If you buy online, be sure to specify same versions of the modules. You are advised to drop the bandwidth to 1066Mhz and raise the NB Voltage +.15v. Please research this thread: http://www.houseofhelp.com/v3/showthread.php?t=64360&highlight=Unpredictable+results+QUAD2X4096+Gigabyte+X38-DS5 There is a limitation of the On Motherboard (Intel) memory controller or On CPU (AMD) 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. You are advised to drop the memory speed from 1333Mhz to 1066Mhz and increase your memory controller voltage +.1v for your X38/X48 memory controller chipset.Download Memtest86+ V2.11 from--->Here Download CPU-z from Here .
