Quote:It would seem Intel's X299 platform is already having some teething issues, with user "der8auer" of overclocking fame claiming the platform is essentially a complete "VRM disaster." In the video in which these claims are made, he levies the blame to both Intel and the motherboard manufacturers "50/50." For Intel's part, he blames them for the short product launch which was pulled in from August to June, giving the motherboard manufacturers in der8auer's words "almost zero time for developing proper products."
In the video, der8auer elaborates to basically claim a completely lack of consistency among the quality of VRMs and their heatsinks in various manufacturers. In his first test, he takes a CPU that is known to do 5.0 GHz and on a Gigabyte Aorus branded mainboard found himself unable to even hit 4.6 GHz with dangerously high VRM temperatures. He goes on to blame the heatsinks on the VRMs, going so far to call the Gigabyte solution more of a "heat insulation" device than a cooler, as a simple small fan over the bare VRM array did many magnitudes better than a simple standard install with the stock VRM cooler attached.
der8auer also went on to criticize the lack of voltage input in the form of many boards having only a "single 8-pin connector" which der8auer claims is not nearly enough. He claims cable temperature of nearly 65 degrees Celsius on the 8-pin cable which is obviously disconcerting, though Techpowerup has been in discussions with renowned PSU-tester Jon Gerow (Jonnyguru) who feels the "all-in-one" cable design on the Super Flower PSU shown in the video may be partially to blame here for the heat level with that current draw. It's hard to tell which part is more at fault for that temperature and we will update that as we know more.

One thing is for certain: The VRM situation is far from consistent at this point in time, and overclocking results on one board may not be consistent to another. Heatsinks may be inadequate, and as far as Overclocking is concerned, it may get interesting folks, and not in a good way. In the end der8auer concluded he couldn't really give a solid recommendation to any of the launch boards put past his desk, all of them having one issue or another with VRM heat at some point.
