stueck9356 Posted November 30, 2012 Posted November 30, 2012 Hey there. This thing is kicking my ass. I recently (yesterday) upgraded to a P8Z77-V pro motherboard, and an i7 3770K. I have looked at how-to's on youtube, googled, and updated the bios to the most recent version (1708) My problem is, when I set my OC up... XMP enabled 42 multiplier cpu voltage, manual, 1.225v cpu current 140% LLC extreme It will not stick. I can load into windows, and quickly load CPU-Z, and notice a 4200mhz overclock. then, after about 7 seconds, it drops to 3500. I can load LinX and do a run, and it will peg itself at 3500mhz. No more. nada. Realtemp displays the same thing, 3500mhz. Prime95, doing in-place large FFTs, will not increase past 3500mhz either. Does anybody know what might be bugged?

El_Capitan Posted November 30, 2012 Posted November 30, 2012 When you update the BIOS, be sure to reset CMOS. Sometimes it helps. Attached some pics to help (on a P8Z77-M Pro, but shouldn't be that much different). Set somewhat similar settings, but don't directly copy the VCore. I have a 3570K that I'm overclocking to 4.6GHz, and watercooled. Share this post Link to post Share on other sites More sharing options...
ccokeman Posted November 30, 2012 Posted November 30, 2012 ALso only use the XMP setting as a guide to load up your memory timings manually. Then go back to manual and make the noted changes. Share this post Link to post Share on other sites More sharing options...
stueck9356 Posted November 30, 2012 Posted November 30, 2012 (edited) I used your OC as a guide, here is my setup.. I uploaded a youtube video of booting up. It's shoddy - it was taken with my phone.. You can ignore the sound of me just fumbling it about update.. changed from XMP to manual, like coke said. Still not working. I also used the "USB BIOS FLASHBACK" button, since that is the only way to downgrade your bios. Went to v1206, since that was what a guy was using in a video I saw, and he had 4.7ghz with the same mobo/cpu. Still same problem..

El_Capitan Posted November 30, 2012 Posted November 30, 2012 Did you reset your CMOS, yet? Share this post Link to post Share on other sites More sharing options...
stueck9356 Posted November 30, 2012 Posted November 30, 2012 (edited) Yeah. Just did that again, after going all the way back to the first bios, 0801. I moved the jumper to pins 2 and 3 for a few minutes. After resetting CMOS, I let the computer load into windows with complete defaults and settle in. Then I proceded to restart and apply the overclock. Same issue. On a side note.. changing multiplier, ram timings, voltages, disabling hyperthreading, etc.. shouldn't the computer shut down completely and then power back on in order to apply the changes? Or do the new motherboards change all of that without fully shutting off? I will hit "save and reset" in the bios, and the monitor goes idle, the fans spin up, then die down and the computer loads. Never does it fully shut off. Edited November 30, 2012 by Snugg Share this post Link to post Share on other sites More sharing options...

Never does it fully shut off. It'll do a reboot. Try disabling Speedstep. Share this post Link to post Share on other sites More sharing options...
stueck9356 Posted November 30, 2012 Posted November 30, 2012 (edited) disabled. same problem. I am trying different things. I installed Intel XTU, and oddly most of the options are greyed out.. This is after resetting BIOS to defaults. Edited November 30, 2012 by Snugg Share this post Link to post Share on other sites More sharing options...
stueck9356 Posted November 30, 2012 Posted November 30, 2012 (edited) Sorry for double posting, but I decided to play around while I think about this problem. So.. I did this.. Unplugged every fan in my computer. Both CPU fans (NF-P12), my exhaust fan (NF-P12) and all three of my bottom intake fans (180mm, come with the silverstone FT-02) Side panel off. Basically only fans on are the three on my GPU (accelero xtreme) and my PSU (which intake and exhaust are both from outside of the case) Ran LinX, max problem sizes. and Prime95, 8 threads (HT is on) Aparently, I can manage to adjust my clock speed, so I ran that up to 103MHz. Putting me at 3.6Ghz. This is after about 20 mintes of just heat soaking the system.. remember, no fans!!

cjloki Posted November 30, 2012 Posted November 30, 2012 i don't have one of those yet but don't you need to disable the c1e and intel speed step, along with anything else that will scale down performance ? those power saving and boosting schemes have long interfered with stable overclocking... Comments...? Share this post Link to post Share on other sites More sharing options...
d6bmg Posted November 30, 2012 Posted November 30, 2012 May be its time to replace BIOS battery? I can see no other reason here. Share this post Link to post Share on other sites More sharing options...

Comments...? I thought so too. That is why I disabled HT as well. But the past few tries, I have disabled every single power saving or scaling down method that is available. May be its time to replace BIOS battery? I can see no other reason here. I jumped the CCMOS, and installed the battery from my last mobo since I know it works. Same problem. I think I will leave the jumper on the 2-3 pins while I am at work, and try again when I get home. If that doesn't work I'll reseat the CPU and if all else fails it's still under warranty.
