X48 8GB 10666 Ram Latency limitation
I recently ordered two sets of G.Skills F3-10666CL7D 4GBRH 2 x 2GB memory kits. I researched the X48 chipset limitations prior to placing the order but was unable to source clear information regarding the latency limitations of X48. Intel's technical whitepaper on the chipset lists 1333Mhz latency as 8-8-8-7. The G.Skills website guarantees their modules are C7 with latency 7-7-7-21-2N. So as I saw it when placing the order, I would have two options; Run only two modules in XMP mode to achieve the G.Skills guaranteed rating, or run all 4 modules, 8GB, non XMP. (X48 supports on 2 x 2GB when XMP)
Two questions; Which configuration performs best for DirectX 11 gaming and occasional video transcoding tasks, and secondly am i correct in assuming that an 8GB configuration will be limited to 8-8-8-7 latency. Incidentally I intend to clock my E8400 at 4Ghz if possible.
If anyone has run a similar X48 configuration, I will really appreciate your advice.
