Some info I wished I could have found on this forum but did not. Cost me lot of money to learn.
Intel i7 Cpu's and Multi-threading. I found on a long search that disabling the multi-threading when overclocking will reduce the heat load on the top end as much as 10 degrees. Do a search, Asus has as a great article on this and by disabling it causes a 5% loss of efficiency but only on special apps.
Does not effect gaming as I read it.
I also discovered that the XMP program in the Bios only works with memory designed for it. I have 3 HyperX Modules that state they are 1600mhz compatible but this is true only when the XMP is enabled in the Bios. The memory without the Xmp is 640x2=1280mhz tops will not run over that.
The reason is when you begin to overclock the cpu the Xmp goes out the window and you have to DISABLE the Xmp in the Bios to get the machine to post. It will not post with Xmp ENABLED in a Cpu overclock not matter how small. The Xmp program was put in the Bios to allow those who do not want to overclock the Cpu to have a little more efficiency on their machines.
So if you are going to overclock the Cpu forget the HyperX modules they are cheap memory with the program for Xmp only. It is a rip off. to sell more cheap memory at high prices with fancy covers.
I have also discovered that overclocking i7 Cpu's will not normally run stable with memory at 2000 and above so shoot for 1600 to 1800 to keep machine stable, someone could possibly add more to this and I am sure there are exceptions but for us newby's this can save a lot of heartache and money, 2000mhz and above is very expensive.
If anyone wishes to add to this, please do so,we newby's spend a lot of money find these basics that should be a part of this forum and they may be available, but I never found it.
