14 DAY TRIAL // It seems that Intel's Core i7 processors do not go well with memory voltage that exceeds 1.65V. The giant chip maker is said to have warned both motherboard makers and memory vendors that its new X58+Core i7 combo would not support memory modules with voltage over that limit. The risk of getting a fried CPU appears once the 1.65V barrier is crossed.
It seems that some pictures of motherboards having stickers over the DIMM slots that warn on the risk of high voltage already surfaced on the web. This limitation hits memory makers heavily, since there are already products that operate at values well beyond that line, including OCZ Reaper PC3-14400 which needs 1.9V, Mushkin’s XP Series that work at 1.9-1.95V, or Corsair’s Dominator high-end that will operate at no less than 2.1V.
Of course, there are also modules that fit the specified limit, with DDR3s starting off at 1.5V, yet, given the fact that Intel's chips proved to be excellent for overclocking in the past, memory makers came up with faster, higher-powered products for the enthusiasts. According to the Inquirer, some of the vendors already started redesigning their modules to fit the specifications.
Mushkin is working on some kits especially made for the X58+Core i7 combo, said VP Steffen Eisenstein, who added that the new Tri-Channel modules should be ready next month. Some other memory makers are also working on the new specifications and are waiting for certification with motherboard vendors.
DDR3 IC and memory vendors will have some work to come up with new enthusiast-level memory modules to fit the Nehalems. As the Core i7 is close to hit the market, users will have to be careful on choosing the right memory kits if they want such a processor, while Intel has to deliver an explanation.
