Core I7-4900/4800 “Ivy Bridge-E” will fully support PCIe 3.0
In November last year debuted intel Core microprocessors i7-3900/3800 Series conociods by its code name Sandy Bridge-E , which were touted as the first microprocessors to support PCI Express 3.0 (PCIe 3.0). But, when it began testing with the first pcie 3.0 video card industry (released earlier this year) the problems started.
Many users of the first Sandy Bridge-E (C1 stepping) had problems in getting run over two pcie 3.0 video cards based on Nvidia GeForce 600 Series GPUs and AMD Radeon HD 7000 Series, this problem was even more severe in the cn video cards Nvidia GPUs, because they refused to work in PCIe 3.0 mode, but you used only da video card (Nvidia released a patch to force their way PCIe 3.0 GPUs ).
The above problems were apparently solved with the launch of the new microprocessors Sandy Bridge-E C2 stepping , which are able to work seamlessly with the PCIe 3.0 video cards and even multi-VGA/GPU configurations.
From Xtreview inform us that future microprocessors ivy bridge-e LGA 2011, based on the Ivy Bridge microarchitecture , to form the new top model of Intel, will fully support the PCIe 3.0 bus, so we have no such drawbacks when used with PCIe 3.0 video cards.
Note that in the Ivy Bridge microprocessors for desktop-DT (Core i3/i5/i7 3000 Series), the problems with the PCIe 3.0 bus is not obvious, as only have 16 lines (lanes) PCIe 3.0, which are shared when used in multi-GPU modes (2x8X or 8X/4X/4X) while Sandy Bridge microprocessors and future-E-E Ivy Bridge PCIe have 40 lines, greatly complicating factor of bus management.
