leka Posted October 2, 2010 Share Posted October 2, 2010 Hello! I have motherboard Asus Maximus Extreme III, and I was going and new memories! Because the ones I have, has very high volt up to 1.8V The motherboard has the chipset P55 and I stand between two memories, first is: CMD8GX3M4A1600C8 8GB Kit (4 x 2GB) 8-8-8-24 240pin DIMM Dominator and the second is: CMG4GX3M2A2000C8 4GB Kit (2 x 2GB) 8-8-824 - 240pin DIMM Dominator My question is which of them I will be most useful? Will I be able to reach 2000 MHz? my current memory is running at 1480 MHZ 9-9-9-24@1.9V and those I have now is not XMP. I want to continue to run with my processor which is to 4.3 ghz so which of those two, I will be most pleased with? I play heavy games, etc. etc. I would appreciate any of this forum will help me Because corsair feels right for me Link to comment Share on other sites More sharing options...
trackrat Posted October 2, 2010 Share Posted October 2, 2010 The CMG4GX3M2A2000C8 is tested and approved to run at 2000 MHz. @ 1.65V. That however does NOT mean that your CPU/Mobo will run at 2000 MHz. memory speed because of the many variables. Your CPU is only guaranteed to run at 1333 MHz. memory speed. http://ark.intel.com/Product.aspx?id=48499 Link to comment Share on other sites More sharing options...
leka Posted October 2, 2010 Author Share Posted October 2, 2010 Thanks for your quick response! I know that the processor does not work with more than 1333 mhz on the memory at default CPU BLCK, right now I have one hell of manual bios, but what's the difference if you use XMP? and then manually clock the processor until it reaches 4.3 GHZ, as I have it now?

trackrat Posted October 2, 2010 Share Posted October 2, 2010 XMP is just a predetermined memory profile that has been deemed to work in many applications - but not necessarily with all memory modules/mobos/PSUs/Video cards, etc. Manually setting the BIOS options will allow you to determine the maximum memory frequency for your particular hardware.

So do you support and think that the best option for me is to set a goal for the 2000mhz sticks? because I know I will reach probably 1800 mhz with the 1600mhz stick with some manual settings.. What do you think? cheers Link to comment Share on other sites More sharing options...

trackrat Posted October 3, 2010 Share Posted October 3, 2010 I'm not sure I understand your last question. If you're looking to run stable above the specified memory bus speed for your CPU then picking the higher frequncy rated RAM, i.e. 2000 MHz. may provide a higher stable speed than a 1600 MHz. rated RAM - but there are no guarantees when it comes to overclocking.

leka Posted October 4, 2010 Author Share Posted October 4, 2010 What would you do? Go for 8 gb of ram, or take the 2000 MHz 4 gb insted? Link to comment Share on other sites More sharing options...
trackrat Posted October 4, 2010 Share Posted October 4, 2010 Do you really have a need for 8 GB. ? If you do photo/video editing, CAD, etc. then you may want 8 GB. If you don't really need 8 GB. and you want to OC then the 2000 MHz. 4 GB. option is better for OC'ing. Link to comment Share on other sites More sharing options...
leka Posted October 4, 2010 Author Share Posted October 4, 2010 Okej I fully understand, But one question, What is the Different between CMT4GX3M2A2000C8 and CMG4GX3M2A2000C8 Do they both support my chipset? P55 The reason I wonder is because CMG cost 100$ more.. Chears!!! Link to comment Share on other sites More sharing options...
trackrat Posted October 4, 2010 Share Posted October 4, 2010 I don't know. Maybe RAM GUY can answer this one? Wait a few hours until Corsair opens for business in California. Link to comment Share on other sites More sharing options...

NEW Memory Part Number Breakdown CMT = CMG + connector for Airflow Pro Both should work on that platform, however your memory controller may or may not be able to handle memory that fast.

leka Posted October 4, 2010 Author Share Posted October 4, 2010 What speed you think i'll be able to reach? I just order them Cheers Link to comment Share on other sites More sharing options...
Wired Posted October 4, 2010 Share Posted October 4, 2010 It depends on the luck of the draw with your CPU's memory controller. Link to comment Share on other sites More sharing options...
