RAM XMP OVERCLOCK :)

Skeng · 20 Mar 2010 at 02:47

Well I decided that I wanted more ram and this morning my new 6GB OCZ Obsidian Triple Channel glorious ******** arrived. https://www.overclockers.co.uk/showproduct.php?prodid=MY-179-OC <--- (Check out link) I already own the Platinum version which is factory OCed to 1866Mhz the reason I bought the Obsidian from OCUK was because in the comments someone said it has a XMP of both 1600Mhz and 1866Mhz.

Now I havent had time to look into XMP yet since I had work and I pretty much just got home now (2:45am). So could someone please give me the rundown on what XMP is and how I can OC my new ram so it may work with my old ram giving me a glorious 9GB experience.

Oh yeah both Voltages and Timings are the same for both new and old ram just the speeds are different

Thanks for reading

XMP will sort the timings voltage and speed for you, may also overclock the CPU a little.

If your motherboard is XMP compatible you will find a memory overclock option in the BIOS, in the list of options will be the XMP profiles. Select the one you want and all settings will be arranged for you to run your memory at the advertised speed.

Poking about with XMP on the P6T: http://www.xbitlabs.com/articles/mainboards/display/asus-p6t_7.html

Your 4ghz overclock will fall flat on its arse when you put three more sticks of ram in. Go back to stock speeds and overclock from scratch.

XMP sets frequency, timings, ram voltage and qpi voltage. The odds of it setting qpi voltage sensibly for your layout are zero. Setting frequency and timings by hand are trivial, so I suggest you ignore xmp and set things manually.

XMP is to deal with the standard newbie objection of "why isn't my ram running as fast as it should". It's of no use to you I fear.

Hotwireds link shows xmp setting qpi voltage to 1.45 or 1.5V. That's well over Intel's absolute maximum for this voltage, and likely to cause your processor distress. Not that Gigabyte nor OCZ really care that much if they kill your processor.

Ah I see so basically XMP is the noobs auto overclock, makes sense never the less I've never OCed ram before and would much appreciate if you could check out my new thread
