In simple words, it's the nº of channels the CPU use to "talk" with your RAM. More channels = better speeds but also more latency. More: wikipedia Most CPUs use dual channel, the "old" Intel's i7 (the likes of 920/930, 950 etc.) use triple channel while the new i7 (3930K) go with quad channel. When buying the RAM the difference is that dual channel kits comes in packs of 2 modules, triple channel comes in packs of 3 and quads in packs of 4.
The combo CPU-chipset (like those of X79, Z68, P67, 990FX, etc) talk to the devices that you install in the motherboard via a series of lanes. This number of lanes are finite (X79 gives you 40 PCIe 2.0 lanes while the 990FX has 42) and are spreaded into the different PCI slots that comes with your mobo. Simply put, the more the better. But be careful with the names, a PCIe 2.0 is different from a PCIe. To learn more: wikipedia
This multiplier tells you the number of lanes the PCIe uses (16x = 16 lanes, 4x = 4 lanes). Every motherboard has at least 1 PCIe 2.0 x16, and this is where the graphics card goes. If you go with SLI/Xfire you must look at the other PCIe slots. When using 2 Gfx cards some boards will split those 16 lanes into the 2 cards (8 for each one). The difference in performance is usually negligible. See more examples here: http://www.hardocp.com/article/2010/08/23/gtx_480_sli_pcie_bandwidth_perf_x16x16_vs_x8x8/ I hope it helps. |
does the 2nd PS-E slot not being 16x reduce the speed and performance
or does it only need 16x in total,8x in one and 8x in other
there should be enough PCI-E slot to accomodate audio card,wifi,bluetooth card
about ram lanes,is it necessary to ram in specific amount or is it just to increase performance?
for example:if i buy 8gbs of ram and cpu support triple channel.and suppose 8gbs are divided into 4 2gb memory.will the 4th memory not work or perform as well?
