I am having some trouble with bios 0803. When it fails to boot when I am trying to overclock the ram past 1200 MHz, I have to switch off the PSU when the system is running, as it becomes non-responsive to holding in the power button.

When I turn it back on, the bios is cleared as if I used clear cmos function.

I still cannot get past 1200 MHz on this board, 1200 is rock stable, 1201 MHz will not boot. This is using any strap. This issue is really annoying me.

Is anyone getting some good results with bios 1201?

I didn't have this issue since 0704 bios, maybe you are pushing the rams and board a bit too much so that it becomes unresponsive, post ya template again plz... also before trying out a new setting I opt to save in an OC profile in case off a complete unforeseen reset.... 1201 with the same settings as 1103 seems to give me a bit better bandwith and lower latency (but no miracles ofcourse)

what might be the problem then Ive tried your template and another 2 and still nothing will it be the bios 803 seems to be good or 1201 sounds to be going well when it's on asus site lol. Could anyone surgest anything to help me out thanks

Try 1201 mate, runs flawless here with the Qx... and try 3.6Ghz first and determine ya Vcore there and post back... could be some pll and GTL tweaking does the trick... Vcore at 3.6Ghz already gives a good idea what will be required for 4Ghz ops... if you are at 1.25 plus for 3.6ghz you can expect pretty easily 1.4vcore for 4ghz ops.... hows ya cooling ?

My ambient room temps are finally cool enough to run 440x8 for 3.52ghz. I am having a problem though. At 425x8 I was able to run my ram at PL7/strong and since I have increased the clock speed it is obvious I will not be able to run at PL7 but I can boot at PL8 and have found that I need 1.46vcore with the CPU and am now trying to pass an OCCT ram test at PL8 but I keep getting BSOD's and OCCT crashes. My ram passes PL8/Moderate with memtest86 v2.01 in DOS. What seems to be my problem? Here are my settings and my set-up is in my sig, thanks!

One of the reasons I almost never use memtest in dos as it seems to be stable there, yet your OS can crash in a flash...I still love XP as it's less hard on ya OC's then Vista... just try to disable static read control and see what gives or loosen to PL 9... think it's time to settle for some slightly looser settings to increase stability... does the CPU and co pass all small tests, ya rig caps out in blend or large mode ?

Try 1.45v to see if volts are the issue - even if you think thats too high for regular use (i dont believe it is), it will identify that is where the problem is.

I wouldn't run my precious Qx daily over 1.4, think he needs to verify all the settings and power connections and get the hang of the board and settings before pushing on... templates are nice but each CPU/Mobo/Ram combo is different... just like women lol
