First off, thanks to the TS and all who contributed to the guide.

Since a few weeks I have a new gaming rig, I've been working exclusively on Macs for the last 5 years so building a PC was a bit of an adventure with all these new-fangled CPU, GPU and RAM specs.

Currently I'm running a torture test at 4.8Ghz for over 40 minutes now. (I've got a Hyper 212 evo cooling the 2500K).
I think the numbers look good: Peak temps are 73C, 79C, 81C, 75C so far, Vcore peaks at 1.400 V.

My question; during the test it isn't running at 4.8Ghz all the time (as I've setup in the BIOS), does this affect the "validity" of the test in any way?

Right now im stress testing at 4.0ghz with a main voltage offset at 0.005 but im noticing higher temps than when i used fixed mode at 1.27 which i ran prime 95 for 20min with and it was stable (1.265 crashed). Should I just go with 1.27 fixed or stick with the offset?

No the test is not valid if the CPU isn't locked at 4.8ghz during the entire stress test. For me 81c is getting a little hot for me, i like keeping all cores in the 70's. Are you using offset mode when overclocking?

Stay w/ offset especially if you plan on overclocking to 4.5ghz in the future. Me and others noticed w/ the Extreme 3 Gen 3 that after 4.0ghz the overclock wouldn't hold in fixed mode, it would start fluctuating during the stress test but w/ offset the overclock will stay locked.

HelloI everyone .I just update my AsRock Z77 Extreme 4 bios form 2.0 to 2.10.Everything ok but now i can't set LLC to any value but 1 or 5.That's a little bit odd because now at 4.5 my i5 3570k needs 1.3V to get it stable.Can i downgrade the bios or i have to wait until new version?

You can downgrade but try this first...

Use LLC 1 and up your Turbo voltage.

Keep Offset at +0.005v (minimum).

Hello kennyparker1337 and thank you for your post.I try with aditional turbo voltage at +0.004v (minimum) and offset at 0.005v (also minimum) and the same 1.31v in load. It's stable with this settings but with llc=2 i have 1.27v max in load.Maybe i will try the downgrade after i get the response form AsRock suport team.

One question about this:

MY PREFERRED CUSTOM TEST
Match the settings to what is in the picture below and use these settings for every test in this guide.

"Number of torture test threads to run" should be automatically be set to 4 or 8 depending on what CPU you have.

"Memory to use in MB" should be set to 512 x # of GB of RAM installed. 4GB x 512 = 2048. 8GB x 512 = 4096.


I have 16G of Ram so my Prime Custom should look exactly like this but with 8192 Mb of Ram used, correct?

Woah, I'm sorry! I made a mistake in my first response.

I meant to say use LLC 5 (NOT 1) and up the turbo voltage.

LLC 5 will drop your voltage way more as opposed to LLC 2. So to compensate use more turbo voltage to reach 1.27v.

Correct.

You can use more than that if you want. It will just stress the memory and memory controller more. I picked half of system because most people have 8GB and most programs are still 32bit and can only use ~4GB of memory anyhow. Although that is for each program, and not together. So by all means, test more if you wish! 50% is just a good medium across the board for all users.
