I7-3770k Single thread stress test

[IInuyasha74]

Hello Everyone,

I have been re-working my overclock lately on my i7-3770k. Before I used a multiplier of 42 and a FSB of 102.7 with a -0.030v CPU voltage offset which gave me a speed of around 4.3Ghz. This was stable for most usage even gaming, but it had random blue screens that happened infrequently.

I like having a small FSB boost, but decided to remove it to try and get rid of my problems. Currently at 4.2Ghz it has been stable for 20 passes in Linpack with IntelBurnTest. I am trying to also boost my turbo speed for single and dual core settings also and have my single thread clock set to 4.4Ghz, but every time I open Prime95 or IntelBurnTest and configure it for a single threaded test, the CPU stops at 4.2Ghz. Not only that, but the other cores jump up to 4.2Ghz also even though they are not under load.

I know I can deactivate the other cores for testing, but feel that might give inaccurate results. Any idea how I might get it to truly test one core?

I don't recommend using turbo boost on overclocks, from what I've heard it messes stuff up.

How about ocing without turbo?? Does it work properly?

Also, how's the temps?

Nah using Turbo doesn't really have any issues so far. That is how most tend to overclock anymore is just by adjusting that. It works about the same as pushing up the CPU core multiplier normally would, with the exception of if the core runs too hot it will throttle down to the default clock speed.

I have an Asus P8Z77-V Pro and it has the option to change the CPU multiplier way down in the BIOS options, but there are a lot less options for it.

My temps are holding well. I currently switched to a +0.030v offset for the CPU, thinking if I am dropping the BCLK down to 100 I should go ahead and give this thing a good push. It's about 8 passes through Linpack right now at 4.3Ghz and the temps are hanging around 75C. I don't plan to take the voltage higher really so temps should stay pretty good.
