I noticed while playing games or running Prime95, I get random crashes of programs such as HWMonitor, Anti-Virus, and other random apps. Can this be caused by my CPU overclock? I notice it created huge window error reports as well

Yeah the same thing happened to me when my CPU wasn't stable. It means you need to increase Vcore.

You're right, Speedstep does lower the multiplier, but it leaves the voltage where it's at. I'm at 4.5GHz @ 1.24v right now stable after 18 hours with all c states and speedstep enabled. I'm also using offset. I guess you just have to find what settings work for your chip. I like using offset so I can have a lower voltage on idle instead of constantly running at 1.24v.

That's what I thought but instead of increasing vcore I decreased my speed from 4.5 to 4.4. Same problem.

I have had this issue as well. It's weird because my stress applications were doing fine, but the monitoring applications would crash.

Trying to OC my i5-3570k. I have it up to 4.3ghz but I can't get the core voltage to go any higher than 1.192. I have it set at 1.2 in the bios however cpuz shows that it won't get that high. When running prime95 the voltage even lowers to 1.184 and will jump back and forth now and then but never over 1.192. I want to achieve a higher voltage so I can try and get to 4.5ghz. Is there any setting I could change other than the core voltage to get it higher? There are three settings in my bios I have not changed that I was wandering if they would make a difference, CPU PLL Voltage, CPU I/O Voltage, and CPU Core OCP Expander (it says it expands the cpu limitations but the cpu is less protected). Thanks.

Fill out your rig and put it in your sig so people can see what hardware you have. It's difficult to help when we don't know what you're using!

The voltage drop you're experiencing is called Vdroop and it is normal. Load Line Calibration is a setting that combats against Vdroop.

Just got my I7 ivy and now looking at buying RAM. From what I have read
Samsung Seems to be the choice of most overclockers here.
I was also looking at G.Skill 4 Different Ones

Does anyone have any other suggestions or a preference on which one you think is better?

I plan to get the Noctua D-14 cooler as well. Anyone here happen to be running on on the ASUS P8Z77-V DELUXE? I'm a little concerned about the clearance but I'm pretty sure it will fit. I saw someone else with the same config on another asus board.

My use will be for a 24/7 overclock for Gaming
(Mostly MMORPG's) Hoping to hit 4.5Ghz with the highest memory clocks I can get.

EDIT: Wow, so Frys, Microcenter, and Newegg are all sold out of the Samsung RAM kits. I could buy 2 single sticks and see if all goes well. Technically there shouldn't be anything wrong with running two random sticks dual channel as long as they're the same model right?

Sorry about that, got my sig set up now. I'll go have a look for this LLC and see if I can find it in my BIOS. Thanks.

No problem. When you say you can't get your Vcore higher than 1.2, do you mean you can't physically set it any higher in the BIOS? Because overclocking sandy and ivy is basically just adjusting Vcore and turbo clock, as well as a few other settings that you can mess with but don't have to. I can't imagine that your Vcore would be locked at 1.2
