Ive got the Corsair H70 (pretty similar to yours), I dont think temps are causing my OC to fail, maybe some other settings, took your advice and changed most thing to auto, seemd to stay stable longer.
I think u were asking me ? I got my i7920 at 3.4 and its really fast at that freq. I may raise it a little more after I get the water hooked up. Probably not more then 3.6. I need ram that runs stable at 1800+ my 1600MHz hyperX is already pushed to 1700.
Going back to your stability I'm not a true expert I aim to sort do it the easy way. If you got it stable at 4.0 or close to that thats really good. Some people say certain multipliers are better.
I ran prime at 3.1 for like an hour that was good enough for me. got to like 78 on air. My 3.4 OC is just humming im not pushing it with prime till i hook up the water. I did run prime and saw temps go to 81 and shut it down.
Your temp is super low thats sweet,
You could try messing with the ram clocks or something if you really want to run it that high ? i just lowered mine a bit but i think you woul have to raise 1 or 2 of yours.
DDR3 ram is 240 pin i don't think they are interchangeable as physically different.
DDR3 is quite superior.
You choose in your bios what you will run the freq of the ram. Therefore you gotta know what freq ram you have bought.
I own 1600mhz ram and i have it overclocked to 1704mhz.
My ram timings came stock 9-9-9-24
I changed it to 7-9-8-22
I read if your overclocking very high u can change some things to make it more stable.
Just google ram timing and overclocking u will find many articles heres one http://www.overclock.net/faqs/26706-info-ram-timings-du...
There are like 16 number fields in ram timings my 2nd number i couldn't change or it wouldent boot and its really advanced crap i barely understand. I only modded 2 numbers. There is ushally a setting in bios that say ram settings or timing or something
