I hope to push this chip to 4.6-4.7 and then i will be very pleased, i can achieve 4.4ghz at like 1.23~ are the other voltages i should look at other than CPU Input voltage and Vcore? i dont wanna lower my ram speeds, cause i paid for the speeds im running at. Any tips to help push this chip a little further will help. Overall i can easily do 4.4ghz at 1.23~ so im happy

You'll all be charted... soon. Ish

Hi all,

I've got a few question regarding overclocking with the UD4H.

1. Do you adjust Turbo Power Limit (Watts) and Core Current Limit (Amps) while overclocking without Turbo Boost?

2. I don't see a CPU VRN Loadline Calibration in my Bios - is that a problem?

3. My current overclock with my 4670k and a Phanteks PH-TC with 3 fans is:
4.4 GHz CPU Core
4.0 GHz Uncore
1.96 VRIN Override
1.34 CPU Vcore
1.2 CPU Ring
Max Temps: 84C in Prime 95 (usually stays around 65C)
What is your recommended addition to voltage? I know that 1.45 is technically the max, but I'm wondering what a healthy max would be.

Thank you very much - Happy Thanksgiving,

D2234

Due to the unnecessary heat and noise while under low loads, since I'd never use the system that way, I saw no real value in testing under manual. I frustrate myself enough with the trial and error time investment tuning my system for every day use smile.gif.

While I appreciate that many do enjoy it and I love reading about the results, to invest that time to say "Well I can do 4.7 under a setting (manual) I'll never use again" is just not something I'm willing to invest time in right now. So again, w/ all the manufacturers saying "No AIDA 64, no Prime95, no OCCT", I went looking for something that would stress the system to the point that I could reasonably be assured I won't experience crashes on a routine basis.

JJ recommended RoG RealBench in Asus' Manual Z87 Overclocking Guide on Youtube and I followed the threads on the RoG Forum a bit before trying. I even asked how folks found it compared to the "ole standards" and the responses both public and private were favorable, basically indicating that if ya "can pass RoG RealBench, you system is likely to handle anything ya can throw at it. This will be a production box (CAD) ....with off hours gaming fun on occassion of course:) ........... and I haven't been able to make it stumble as yet with the settings I obtained running RealBench

If ya wanna give it a try.

http://www.necrosan.com/rog/RealBench/RealBench_v2.0b10_RC6_public_beta.rar
It has both benchmarking and stress testing mode.

Thanks for this info! I am definitely going to try this, I think I am done with Prime95.... I'll probably use a combo of Realbench, X264, and Intel XTU.

1.45v is not the technical max. I don't know where you heard that. I believe the max on my board is 1.999v for vcore. I forget exactly, but it is definitely much higher than 1.45v

YUNO have updated sig rig? I'd love to help you with your LLC problem, but can't because I have no clue what board you are using. You definitely have a setting for it, but it seems that every board manufacturer likes to use their own terms for the same exact settings.

As for suggestions moving forward, make sure you reset all settings to default and test core stability first. I'd suggest using x264 to push further because you will need less vcore than P95 stable (depending on which version you are using) and will have less heat. Not to mention, you will see real world temps with it and can see when your cooling solution is your limiting factor in your overclocking.

You are more than likely going to be VRIN "limited" before you hit a vcore "limit" But you're true limiting factor will be your cooling solution. I'm not saying your cooling is bad, but it will most likely limit your overclockabiliity unless you get a chip like Darkwizzie's and are limited by a voltage wall where it's just plain stupid to move to another multiplier because the voltage jump can't justify the slight increase in performance.

Yeah, until you're playing games and it falls over.

Too many people in this thread waste time doing stress tests. Get it what appears stable and then start gaming - if you're good, then you're good. Why anyone would bother doing 6hours of Prime is beyond me. Sure I did that on my SB back in the day @ 1.54v for 12hour run just cause I wanted it posted and it was <80 degrees but today, either I'm too old now and just don't care or something else.

Didn't think any ASUS board used the term VRIN. Anyhow, SVID enabled and then it's respective Voltage Override is also on the Z87-Pro, I've yet to see what exactly it does. It certainly doesn't raise Input Voltage under load/idle.

Woah, really? What is VRIN then on asus z87 mobo's :S

Edit: whoops sorry, I'm tired tongue.gif got SVID override voltage and CPU Input Voltage mixed up. Yeah I just left SVID on auto from memory. CPU Input Voltage is on 1.950v

I thought my x47 clock was stable, sure x264 for 10 loops so far with mem at 1600 1.5. I thought I could be cool and try xmp. 1 hr later, bsod 124 with Crysis 2 biggrin.gif
post #6138 of 19603
Been trying this Realbench, looks like fun as it has a bench too but it is still using an old version of x264 (version 2273 compared to 2377 .. so about 9 month old). Still better than the very old x264 bench.

1.45 is safest max on air according to Intel is what I am referring to (http://cdn.overclock.net/f/f5/900x900px-LL-f5315882_vku3.jpeg).

I'm using the same board bios as Sin0822 (http://cdn.overclock.net/7/7a/7a0d7199_5m3.png). He seems to have an extra screen than me. I don't see 3d Power Control anywhere.

What is the max temps you'd recommend?

What is the max temps you'd recommend?

Depends on the stress test for what max temps are okay. For P95, 90C is as far as I would go. With something like x264 it's really up to you since it is what you'll be seeing under load. I personally don't want to see above 75C max while under load. That's just me though.

I agree that over 1.45 is probably not safe to run 24/7 but it definitely isn't the max you can go, that's all I was saying.
