Change vcore to manual vcore and change it to 1.2000vcore.
Make CPU ratio to 40 and check stability of that for about 30 minutes. Post your results here.

sounds like a plan, my Vcore was 1.272 and VID 1.266 when Vcore was AUTO & Offset was AUTO (+) with 42x, so perhaps starting at 1.200 may work although my voltages seem high compared to others for this mild OC.

EDITED: Swag, I also just proved something this morning on my own and through some searches. Prior to my upgrade from BIOS 1504 to 1606, I could re-start (warm boot) and still enter BIOS, but now that I have 1606, it seems like my POST is either too fast or re-start is taking cues from the OS and not letting me get into BIOS thinking this speeds up a re-boot to the OS. I even found something on microsoft.com about it, so maybe I just have to shut down, wait a few secs and then push the power button to re-enter BIOS to continuing stepping the OC'ing. Not ideal, but I've had no problem producing that 2 times then had to get to work...so maybe the OC at 42x was stable. what do you think? I'd still appreciate doing this "live" with you regardless as this minor issue has made me a bit gun-shy.

there's one thing I am missing in all of this now that I am trying to reach a baseline OC for your comments and help....how do I set up prime95 as it seems many set up differently and therefore your OCs may be different results. I understand the ways to use it, but in this case where I am trying to find my best OC do I:

Use custom blend and leave the lowest and the highest FFT settings to run all the way thru the FFT sizes or change the sizes?

How much time do I give it to run each FFT test? If I am supposed to be checking this for a small amount of time, say 10-20min, to find my proper voltages and then try to adjust higher multiplier, etc, how will I learn anything if it hasn't completed even one full test?

And if I use 90% of my available memory isn't that testing memory more than CPU or is that just a nonsense thought b/c they always work together and why the guide suggests this setting?

I am reading so many conflicting ideas, but I'd like to know from those doing this using this guide. I'd like to hit the start button and not over-think this, but without these answers, I am not sure what what kind of stability I'll be proving when I post my results.wackosmiley.gif

Small FFTs are ideal for older CPUs. They are NOT ideal for the new CPUs. Here's why: The new Intel CPUs have IMC, whereas, their old CPUs, do not. IMC is Integrated Memory Controller and thus making "RAM stressing" with CPU stressing critical. Most people generate more heat under Small FFTs but you are limiting what you are stressing with that. Now, CPU's are two parts. IMC and the actual CPU part. With Small FFTs, you leave a huge chunk of "instability" left unchecked.

I hope this cleared it up to you why using blend is more ideal for the new CPUs. A lot of my problems during stress-testing are the higher FFT sizes which stress the IMC.

Sounds like a plan, tell me how you want to do it and when. I tend to be on a bit late at night since I am on PST.

Actually, you don't need to do that. Go into BIOS and look for a Fast Boot option and put in Normal Boot. This way, it shows the Asus Boot logo and it won't skip through it. Of course, another option so you don't turn off that feature would be holding down "Del" right after you press the power button. Holding it down makes the BIOS know that you want to go in it and switches from Fast Boot into Normal Boot.

For now, try doing 1.2000vcore until we can get a time set. I try to help as much as I can, but ultimately, it's you who does the hard part. I guess I'm just the median. tongue.gif Anyway, for Ivy Bridge CPUs, as long as temps permit, you can go up to 1.40. I ran 1.37 for a while for 5GHz and I never saw any degrade from any of my other OCs. Everything still stable and they can all still pass 12hr Prime!

1. Use custom blend with all FFT sizes. Do not change the FFT sizes, they are critical to your stress-testing.

2. Change amount of time to run each FFT to 10 minutes. This allows it to run all FFT sizes in 12 hours. 10 minutes is minimum as well to run a FFT size so don't go lower than that. 10 - 20 minutes is to find a baseline and basically see how low your voltage can go. It will almost always increase by quite a bit from the lowest vcore you could get it to.

3. 90% of RAM because IMC is now integrated into the CPU and making it critical to stress your IMC as well. More RAM used = more stress to IMC.

Hi all, could I please get some feedback on my OC so far? This is a i5-3570K on a Maximus V GENE.

I have my BIOS configured exactly like the guide says. Below is each attempt at running Prime95 for 10 minutes on Blend using 90% of my memory as the guide said. First using Offset Auto Vcore, then switching to Manual Vcore after my first crash.

(Key: Vcore - Multiplier - Max Temp)

Offset Auto

1.192 - 42 - 69
1.192 - 43 - 70
1.200 - 44 - 71
1.200 - 45 - 70
1.200 - 46 - 72
1.208 - 47 - 71
1.208 - 48 - Crash

Manual

1.210 - 48 - Crash
1.215 - 48 - Crash
1.220 - 48 - Crash
1.225 - 48 - Crash
1.230 - 48 - Crash
1.235 - 48 - Crash
1.240 - 48 - Crash
1.245 - 48 - 78
1.245 - 49 - Crash
1.250 - 49 - Crash
1.255 - 49 - Crash
1.260 - 49 - Crash
1.265 - 49 - Crash
1.270 - 49 - Crash
1.275 - 49 - Crash
1.280 - 49 - Crash
1.285 - 49 - 84
1.285 - 50 - Crash
1.290 - 50 - Crash
1.295 - 50 - Crash
1.300 - 50 - Crash
1.305 - 50 - Crash
1.310 - 50 - Crash
1.315 - 50 - Crash
1.320 - 50 - Crash
1.325 - 50 - Crash
1.330 - 50 - Crash
1.335 - 50 - Crash
1.340 - 50 - Crash
1.345 - 50 - Crash
1.350 - 50 - Crash
1.355 - 50 - Crash
1.360 - 50 - Crash

I stopped here as I was hitting 96 on max temp at this point, so I didn't see any reason to continue.

Any recommendations? I haven't ran any other tests. Looks like 4.7 could be a nice sweet spot, or is it worth it to try stabilizing 4.8/4.9? Is there any other setting I should change in my BIOS to lower my voltage at the higher clock rates?

Thanks!

The OC benefit really stops at 4.5GHz and anything over isn't too beneficial. It stops being worth it for the temps and volts. 4.5 - 4.6 would be a great OC.

Got my 3770k, thing is amazing compared to my i5. Passes prime at 4.5GHz @ 1.18v, requires 1.21v for no WHEA errors at all so that's where I have it. Topped out at 86c.

For comparisons sake my 3570k needed 1.25v for 4.4GHz and topped out at 94c.

My i5 had a VID of 1.29v, my i7 has a VID of 1.20v.

i agree with you swag. over 4.7 ghz only benefits in term of benchmark. correct me if im wrong.

thank you. excellent explanation for settings and reasons! I'll test 1.20v with these prime95 settings and will PM to set up time.biggrin.gif

That's great to hear. It looks like you are gonna have fun with your CPU! I was planning to switch my i5 to an i7 but since my chip can do 4.8 at 1.264, I don't want to complain. tongue.gif It does what I need to do and I'd rather save the money for something else like getting my server for folding. I wish I can fold more, but with the hot temps right now, I don't think I can do more than what I'm already doing.

Anything above 4.5 is generally overkill in terms of benefits. 4.5GHz vs 4.7GHz, you will see 1/2FPS increase in all games basically, and the reason why I chose 4.5GHz rather than 4.6GHz for the OC benefit stop was because in general, more chips require a whole lot my vcore for 4.6 rather than 4.5. Like the scaling becomes wacky.
Most chips might need around 1.26vcore for 4.5 and most need 1.32+ for 4.6. That increase in vcore or temps isn't worth that 1/4FPS to me.
