Let me know what you guys think. I think I have a successful overclock?

I ran Prime95 for 20 mins.
I am using Corsair H60 with a mod and using 2 fans.

332

324

Coretemp and CPUZ show different voltages, anybody know why?
Sometimes it drops to 1.1760, but then goes back up to 1.1809.

I have 1.170 set in BIOS, and for the sleep states I only disabled Thermal Monitor. I have enabled High Perf, Fast, Turbo settings, I forgot what the names of the settings, but it is in that order.

Ok gentlemen,

I've been having an issue that I'm not so sure anymore is a GPU issue but something not set right with my CPU settings.

I've been having Crysis and Crysis 2 'not responding' error messages. Black screen on one occasion. A ctr+alt+del can quite task easily. I've not had any forced reboots.

I thought it was a faulty PSU (new AX850) but swapped it out for another new PSU and same issue. I'm now thinking perhaps one of my new RAM sticks is bad so I'm going down that tideous route.

RAM is set for it's default 1.650v setting.

However it dawned on me that perhaps settings on CPU in UEFI BIOS aren't set 'auto' correctly. I'm stock CPU / GPU / & never OC Ram.

I've had to force DRAM memory to 2400 MHz because it always defaults to 1300 MHz.. I've turned off stepping and C1 (disabled).

What should my default voltage, VCCSA, and DRAM be set for? I'm a bit lost if 'offset' voltage should be on or manual. If it should be set to (+ or -) as well.

I'm about to send back my GTX 690 thinking it's the GPU failing and if that's the case good luck on me getting a replacement. Anyone?

Check the eventlog, under windows logs\system.

Does it do the same thing at proper stock ram, as whilst you are not OCing your ram you are OCing the memory controller. I'd also immediately check the ram voltage that the usual programs thinks you are seeing as that might scale with speed and you'll be well over the recommended voltage for the ram .

Ahhh... look at this my very first overclock thumb.gif Only took me 30 years of life to accomplish this:p.

I've set my bios to a very meager 42x100 because I knew that would not have to change the vcore with that quit yet.

I'm having a ton of trouble maintaining a stable overclock on my 3570k. When I enable the turbo boost in the BIOS, it overclocks my CPU to 4.6 GHz. The problem is that this isn't stable at all. My PC crashes within about 1 minute... I reverted everything back to stock clocks. I also can't get my memory to overclock past 2GHz. (It's a 2133 MHz set)

I must be doing something wrong... I'd really like to overclock this processor, but I'm having very little luck getting any kind of overclock without great instability. Help would be greatly appreciated.

From my recent and brand new experience with overclocking an ivy bridge(specifically the 3570k), I have turbo boost enabled and at the moment I have the multiplier set to 45, but I started out with 42 like it says here. So try 42, and set 42 for turbo boost(all of the active states).

So, maybe start out at 42 first?

I think the memory controller or the chipset(not sure which one) only supports up to 1600mhz and in order to run 2133mhz you have to overclock your CPU first. Starting out with 42 should work.

And don't overclock your memory until you are finished overclocking your CPU first. Make sure it is stable. I ran prime95 for 20 mins. Keep an eye on your temps, I use coretemp.

42 is a great place to start. Good job.

Maybe run for 20 mins next time?

What CPU cooling are you using?

Turn off turbo and change the default multiplier instead. Turn off all power saving states C1E, C3/C6, EIST, etc. set the voltage to whatever the BIOS shows stock next to Auto (instead of Auto). start with whatever your turbo multiplier normally is. If it's 39 on one core, set it so that's your default frequency. It should be able to handle that on the stock volts. Do a quick stability test (20-30 minutes of prime. If it works, jump the multiplier to 40. Go into windows, repeat the 20-30 minute stress test. If it passes, go to 41. If it doesn't, give the voltage a few bumps up. Keep repeating the process smile.gif

I'm confused. When I set the clock ratio to 42x, and disable turbo boost settings (for optimal results), I do get a 4.2Ghz OC no problem, but when I set turbo boost, C1E, C3/C6, and CPU EIST on, and I increased the Turbo Power limit to 300watts and Current limit to 200 amps, it only overclocks to the 4-core turbo ratio of 3.60Ghz. What am I doing wrong? All I want is for turbo boost to lower the clock while in idle and boost up to 4.2GHz under load.

If you want it to drop while idle, you have to use offset and not manual voltage. Why are you changing the Turbo Power limit and Current limit? Especially for that OC, you shouldn't have to do that.
