ASRock X58 Extreme + DDR3 1866

My fiance and are I planning on putting these two components together in her new i7 box:

MB: http://www.newegg.com/Product/Product.aspx?Item=N82E16813157163
RAM: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231262

However, the Newegg specs indicate that RAM over 1066 is only available via "OC"... could someone explain what this means to me?

The default memory multiplier for the i7 920 is 8x (2:8 FSB : DRAM ratio), so w/ a default BCLK of 133MHz the resulting DRAM frequency is 1066MHz. So in order to run the RAM at a higher frequency without changing the BCLK, the DRAM multiplier needs to be manually increased from the default of 8x to 10x or 12x for example. A 10x or 12x multiplier results in either a 1333MHz or 1600MHz effective DRAM frequency (considered to be OC'd) at a 133MHz BCLK. In the Chipset Settings menu of that board, you just need to select a particular DRAM frequency from the list of available options. If the 14x (2:14 ratio) option is available, then the resulting DRAM frequency would be 1866MHz. Otherwise in order to reach that frequency at a lower multiplier, the BCLK would need to be increased from the default.

Sorry for the late reply. Holidays are butchering me.
Thanks redduc, that makes perfect sense and played a part in us getting the 1688 (or there abouts) mhz stuff since the lady wants to OC her i7.

Cheers.

I have a ASRock X58 Extreme3 and want to know if this is normal:


If I set in the Bios Overclock mode from Auto to Manuel and i save it and then when i reset my computer my computer shots down and 3 a 4 second
my computer comes back on again.

I have don OC many times on Computers, and what i know it's not normal that my computer will do that, or is it normal that he do that?

Also with the newest Bios he dos that, If i only set Overclock mode from Auto to Manuel, and not OC anything and save, he will turn off every time when i want to reset my computer, and then Windows will load and when i
reset Windows my your computer shots down and 3 a 4 second my computer comes back on again.

But do you all have this when you OC with this MB, or with the ASRock X58 Extreme?

If not i gone RMA this MB for a new one.



I have sent a E-mail to ASRock but i hear nothing from them.
