For beginning I must recommended for YOU full of review with description of the board:
Asus-Rampage-V-Extreme-review-OC-and-some-fun-bonus
, BIOS description etc...But for someone can be interesting only this part of overclocking...

Part with overOCng. For reminder, my cooling system is simply Noctua NHD14. I tested in AIDA stress test for 30min. I tried two combination. One with BCLK around 100 MHz and second with STRAP 125. I pushed memory clock to the higher clocks and cache clock also. Stabilize high cache, RAM and CPU is very stress for CPU overall, so with lower cache and decent RAMs you can get CPU frequency around +100 MHz higher.

Decent profile

I started at "decent" 4200 MHz. 1.22V was necessary for full stable of my retail piece, RAM 3200 MHz and cache 4 GHz. Load stress temps in AIDA stress test were between 75-80 C, not bad.

The best stable performance profile-named OC1 in graphs

It was very hard to get stable 4300 MHz, now I need 1.32V, power consumption jumping up (as you see later in graphs). Temps up to 93 C, small reserve is still here :). I tried 4200 MHz cache, but it was not full stable...

Second stable performance profile with 125BCLK strap and a bit lower cache and memory clocks-OC2 in graphs

For 4376 MHz I tried temperatures limits, but not why. Right overclocker must pushing to the limits sometimes :). Cache clocks was here 3876 MHz (is mistake in description note at printscreen) and RAM 3000 DDR4. I set cpu voltage to the 1.35V, for AIDA stress test hitted temps over 100C, yeah baby:D. This profile has similar average performance as OC1 with lower CPU clocks (but higher cache+memory). Sometimes is better, but lower cache and memory clocks are for some tests important...

old bench days-Cinebench R10, I started promote it for hwbot many years ago :)...


So time for graphs




-the higher cache in OC1 profile and better RAMs means in memory tests clearly win.




-ufff, all modern chips are so quickly in wprime1024, but under 100s now with air?!


-Frtizchess test over 30k points? Wtf?! Where are the times when I was happy for 10k barrier 🙂



-Cinebenchs are so awesome for this monsters


-ideal CPU for x264 (and sure for x265 4k) video encoding 🙂




-Far Cry II is very sensitive for CPU (in lower resolutions specially). I had not tested 4960/3930K in this benchamrk and I do not bulid again this CPUs for only few tests...So for Far Cry II graph I changed these CPU for i7-3770K and FX-8350.

Power consumption for 5960X after OC is really big. Big chip, higher voltage= overheating, more current suply, need VRM active cooling. 390 Watts is without GPU load, so with GPU could be around 500W (270X-r9 now)



This is not all, later max benchmarks at air and we will se what happens with LN2 later :). Im afraid from old SF3D LN2 pot...Petri or Ryba, can me change old one for new one for free?:D

To OP:

Thanks for the thread.

Im running a 5960x too, but on a Corsair H80i w/ aftermarket fans.

I was running a rock solid stable 4.0ghz (40 x multi, no other changes) with 1.35v core. "warm" Idle (ie, sitting idle but after a long session of Elite Dangerous) temp was about 43C (with fans spooled down to totally silent mode) and Asus RealBench load (H.264 video encoding test) temp was about 69-70 (and fans spooled up, of course).

I saw your post and tried dropping my own vCore down to 1.22. Now idle temp appears about the same +/- error, it's sitting at 43C now but load (same stress test) is 62-63C (down from the 69-70 before).

Thanks for your post. I have not tried pushing the ram past 2133 because I was getting hung boots before, and the Samsung XP941 I'm using as a boot drive is very sensitive to this and gets its MBR corrupted easily, requiring a full windows reinstall from the DVD (The recovery options don't work). Im tried of reinstalling windows and setting up all my stuff, so for now, I've left the ram speed at 2133. But 1.45v on your ram?? Its that crazy high??

1.45V is OK for Predators with high heatsinks. Example JEDEC DDR4 is 1.2V, but XMP profiles is defined as 1.35V. So + next 0.1V is still safe for high clocks. Its something as 1.75V for DDR3 and its OK if you have good memory. With DDR3 you cna push it around 1.85V for air benchamrking and with LN2 around 2+ V :). Of course all at risk.

But Im sure, 1.45V DDR4 is OK with good airflow inside the PC if you really want one step tighter timings or +200 MHz clock. For daily using is better try example 1.35V and 3200 MHz with 16-16-16-37-1T.

Part with max OC benchmarks.
This CPU is nothing special. I mean, sample of average chips in 60-70% of users (because most users will be not showing how bad CPU is in OC 🙂 )

We know, max stable settings is 4300 MHz (If you read last chapter). So I hoped for 4400 MHz. And this is exactly the limit of the CPU with my cooling.

Cinebench R11.5, with higher cache I got freeze at this CPU clock.


HWBot PRIME at 4411 MHz


Wprime 32M and Wprime 1024M 8C/16T 4400 MHz



Winrar 8C/16T, wow almost 22k KB/s



need it more voltage 🙂


8c/8t Superpi 32M 4536 MHz and 4549 MHz




Max Superpi 4C/4T. CPU vcore now at 1.45V, 4662 MHz




Max Superpi 32M 4c/4t, 4623 MHz



Max idle 4C/4T 4721 MHz, 1.45V
