hmm, i cant be the only one using ddr3 ram? anyone else have any experience with ddr3 memory?

helmutcheese 1.9v sounds ok to try out, i just checked the specs for corsairs dominator ddr3 ram and its rated at 2v stock, although mine is not dominator memory so not sure if i could take it up to those sort of volts. im trying to find out now if there dominator ram uses the same sort of chips as my xms3 dhx stuff uses. since i suspect that my ram may also hit the dominator speeds if i shove 2 volts up it.

need to see if others have tested this before though before i progress.
 
here is a bench in everest of the ram running at stock 800mhz speed and stock 7-7-7-20 timings just incase anyone is interested:

ahh thanks for the reply, does that mean that the xms3 dhx1600 ram i have uses the ram chips as the dominator stuff? (but probably speed binned so wont get as fast as dominator ram i bet)?

also would running it up to 2.0v void the warranty? since its rated to 1.8v on the corsair site.?

and finally, how hot does this ram get if its run at 2.0v 24/7?
thanks.
 
I don't have any personally to test so I am relying on one of my fellow lab mates feedback. The DHX cooling is the same internally as the Dominator so heat is not an issue at 2.0v. I don't have specific temps but 2.0v will not cause heat issues, especially if you have good case airflow. If you want to take extra steps, a fan is a good idea. And, yes it is binned so my guess is you will probably be able to hit somewhere between 1600 and 1800 with it but there are no guarantees of course.

You are fine up to 2.0v and within the warranty. 1.8v is the tested spec but we allow some tolerance due to various factors such as MOBOs under or over volting, etc.
 
excellent, thanks for that info yellowbeard, i just realised that your an official corsair representative so thats awsome stuff there. i will get testing on the ram later on this week and post my results.
 
not having much luck with the overclocking, i put the voltage up to 2.0v and set the fsb for 450mhz and reduced the cpu multiplier, keep getting failed posts even at 9-9-9-24 timings. lol just my luck i bet.
may try 425mhz to see if it works.
 
ahh i have gigabyte P35T-DQ6 board. chipset voltage i believe is the MCH voltage setting in the bios, how much extra should i add and whats the max safe limit to use?
this is the board in question: http://www.gigabyte.com.tw/Products/Motherboard/Products_Spec.aspx?ProductID=2636

thanks

oh just to add, i thought increasing the mch voltage is only beneficial/required when you have 4 sticks of ram in the system?
