Lost Circuits posted a review on the Foxconn C51XEM2AA Motherboard

nVidia's releases of the nForce 590 SLI chipset and reference designs have been implemented one way or the other by a number of manufacturers - each of which has added a little bit of his or her own secret sauce to make things more comfoming to the rest of the product line-up, shave off a few pennies here and there or simply "because". There is, however, Foxconn, who manufactured the original , nVidia-internal reference boards. Reference boards have in the past always stomped the final production versions - in terms of performance and reliability and, often enough, also in terms of overall compatibility. Reason enough to greet reference boards with a bit of skepticism. However, in this case, we have a one-to-one conversion of a reference design into a GTO production - with an unspeakable name, produced by Foxconn and sold at a perfectly acceptable price.
