I found that uping the input voltage helped with one of the overclocks I was playing with, and mine was much less extreme, 4.3@1.260v. Yes that's how bad things are for me. And this is with memory running at 2133.
I can't be this unlucky a third time surely? I must be over looking something. I had a rubish 4770k, 4790k and now a 5930k. Both my sandybridge chips (2600k,2700k) hit 5 and 5.1 gig on less than 1.3v.

Anybody got any advice? I'm currently using all stock settings except for multiplier (43) and Vcore (manual 1.255v) imput volts back on auto (1.840), memory on auto so running at 2133mhz.

AI suite is showing ram to be running at 3100mhz, but it isn't. Also I'm not liking fan expert, it seems to do it's own thing regardless of when I set. And so does the bios fan controls. Maybe it is because all my fans are 3 pin.

In AI Suite my ram also shows it is running @ 3105mhz, when it isn't (my ram is running @ ~2133mhz). I'd ignore that figure if I were you and just use the numbers from CPU-Z or something for confirmation (unless I'm missing something as well in AI Suite?). I wouldn't say 4.3ghz @ 1.26 is abnormal so to speak, just perhaps tiny bit more volts than some others can achieve. My 5930k would do 4.3ghz @ 1.29v with my previous Gigabyte X99 Gaming 5 but somehow on my newer X99 Deluxe it runs 4.6ghz @ 1.296v. As far as fan expert goes I'm guessing that could be down to your AI Suite version or BIOS or fan characteristics. I find that Fan Expert works really well for myself but only after I did the fan tuning/calibration thing.

I think it is probably my fans because they are old.
Congrats, 4.6@ 1.296v:toast:, I would be very happy with that. I just set LLC 6, and enabled VRM spred spectrum to no avail. Still crashes before XTU can finish benchmark:(

Tried 1.275v, crashed again in XTU bench. Something must be wrong somewhere, maybe I should check that all my cables are plugged in properly or something. I have loaded the 6 core gamer oc profile.
core 0=45
core 1=45
core 2=45
core 3=43
core 4=43
core 5=43
Vcore =1.350v
LLc 9
CPU input voltage 1.850v
CPU powerphase =extreme
CPU VRM switching freq =500khz
CPU current capability =140%
CPU power duty control =extreme
mem still at 2133mhz
All seems about right for 4.5ghz. XTU completed without crashing but I can not try anything like OCCT or Aida because my ageing H100 is not performing adequately at the moment (mite have to swap it for the WC loop in my gaming rig). Didn't hit 4.5ghz in XTU only 4.3 so it didn't get hot.

Live or Die... any reason you are adjusting the input voltage at non extreme clocks?

Increasing CPU input voltage some times makes it easier to get a lower vcore also it depends on your CPU like mine needs 1.91v when running AVX @ 4.4hz removing it and i get a BSOD.

4.5Ghz stable 1.29v / 1.85 input voltage / LLC 6 .

I test with a couple of things (Sorry about late reply)
Prime95 is still one I like to use, I normally test for 30 minutes to get a beginning of stability checked and then after I have everything confirmed I do it once again as part of a Burn in for a long period of time (Generally a couple hours depending) for final temps and to make double sure. I also use Heaven, AVX2, FireStrike (Mostly for fun), Pi, CineBench, and a few random depending on what I hear is a good recent one. I change when I hear about new ones or programs that are getting better checks for certain processors or just are now better for checking.

As for settings, well my settings (I checked this weekend but forgot to post and I am at work so this is off memory) were 1.275 for VCore and manually entered the ram settings for this system which is about the extent needed for my 4.5ghz overclock which was fairly easy to find (Stability wise), I plan on going back alter and trying some additional changes to try and lower the Vcore a bit when I have some extra free time. To achieve 4.6ghz I got it after playing around some more with settings to 1.295 Vcore, Ring (I believe) 1.10-1.2 (Cannot remember exact ill again have to double check), and then bumped the input voltage up a bit which got me some good stability which I may go back to (its a saved setting) but for right now I am more than happy at 4.5ghz on it. I have not devoted enough time to playing around with changing the input and such to see if I can get that 4.5ghz lower because I have been to busy and actually not been using it much lol.

Not enough time in the day sometimes with my recent position change at work along with a move, however this week should allow some extra time that I may go for a bit of playing.


Prime95 or any AVX stress tool I need stupid amounts of voltage as I don't use any think AVX and if I do it will never put full load on my system, I don't tune using it I use linx 0.6.4 and aida64 and test for 6+ hours.




UPDATE!!!!

Well LLC on auto isn't Level 9 for me i did a quick test with VCCIN set to 1.85v Also if you set auto in the bios and change it in Ai Suite Level 9 becomes the auto setting, You have to select a Level in the bios i selected Level 6 here's what i found.


LLC Auto vdroop = 1.792v - 1.808v ( Level 6 )
LLC Level 9 vdroop = 1.856v - 1.872v ( fluctuation )
LLC Level 8 vdroop = 1.840v - 1.856v ( fluctuation )
LLC Level 7 vdroop = 1.792v - 1.808v - 1.824v ( fluctuation )
LLC Level 6 vdroop = 1.776v - 1.792v - 1.808v ( fluctuation )
LLC Level 5 vdroop = 1.776v - 1.792v ( fluctuation )
LLC Level 4 vdroop = 1.760v - 1.776v ( fluctuation )
LLC Level 3 vdroop = 1.728v - 1.744v ( fluctuation )
LLC Level 2 vdroop = 1.712v - 1.728v ( fluctuation )
LLC Level 1 vdroop = 1.696v - 1.712v ( fluctuation )

LCC doesn't seem to give much Vboost on my system even on LV9 i would say its safe to run it on LV8 as its very close to what you set in your bios.

I just ran a quick 5 minutes LinX 0.6.5 AVX test with the above LLCs Now my system isn't stable running LinX even for 5 minutes i normally get a BSOD and seems like LLC was the problem after setting LLC to Level 8 i was able to run LinX for 5 minutes the LLC settings below all failed.

No idea but AVX now fails again with a BSOD when reusing the settings it passed on just before .

So to high a LLC can cause instability? Can high temps cause a Bdos, 85-95c? (I stop when I see these temps, if I don't get a bdos first)

I have not been able to get stable at 4.4 because I don't have good enough cooling, I don't want to go past 1.325v cpu core at the moment.
I dropped back from 4.4 to 4.375@ 1.325v but this time with ram at 3000mhz and 125 strap. Still unstable, crash after a few minutes of linx 0.6.4 and real bench stress test test with 16 or 8gig of ram (stable with 2 hours of BF4).
These are my BIOS settings.
125x35=4.375, 3000mhz
CPU Manuel--1.325v
CPU system agent--+150 (1.034v)
CPU input voltage--1.910v
CPU LLC --6
CPU SVID support--Disabled
CPU power phase control--Extreme
CPU power duty control--Extreme
CPU current capability--140%
CPU power thermal control--120
Fixed VRM switching freq--500
Dram V--1.35
Dram SVID support--Disabled
Dram current capability--100%
Dram power phase--Standard
PCIE clock amplitude--Higher

Is it likely that I can tweak a bit more to get stable, or improve cooling, or is it simply a case of my CPU needs more volts to do these clock ratios? What do you think folks.

Never let your CPU pass 85c your BSOD are more related to a to low Vcore.
The higher LLC you use the more the set CPU input voltage will hold closer to what you have set in the bios, Seeing your using Linx 0.6.4 i can get my system stable on 4.5Ghz with 1.295v LLC 6 input 1.85v but i have been using LinX 0.6.5 which needs a lot more voltage than 0.6.4 my current overclock is 4.3Ghz @ 1.25v LLC6 1.85v . Seeing your using 3000Mhz ram to get this stable you need a very high system agent voltage to stabilize the IMC best to remove your memory overclock run your memory @ 2133Mhz when testing your CPU overclock once you know that's stable then add the memory overclock and start working to stabilize that.


Nothing special here just a 4.3Ghz overclock AVX2 stable this test fail after a hour on 1.24v , As i use this system for gaming I'm happy with this overclock the extra 100mhz for 1.32v isn't worth it, And ill rather be as stable as stock clocks and be able to run AVX stress tests with no problems, A lot of people turn there overclock using realbench or aida64 but both of these fail vs LinX 0.6.5.

Thank you Live or Die. I had been trying to get a stable 4.4ghz with 2133mhz mem but temps would not allow it, as it seems I would need to give the CPU more than 1.350v. I was hoping that there mite be something else other than raising Vcore that would help stabilise. I realise high temps can causes permanent damage to the CPU and reduce it's performance, I was just wondering if high temps could cause instability because I felt sure 4.4ghz should be achievable on 1.350v

Right now I'm at 4.250ghz, 3000mhz mem with 1.260vcore, 1.032v system agent and 1.870 input voltage. Hopefully these volts will all come down a fair bit. Once I have lowered the volts I will move on to OC'ing the cache (and probably uping everything again).

Anyone here using anything but the basic V settings on the Rampage V or X99 Deluxe to achieve their OC?

Benchmark Scores Faster than yours... I'd bet on it. :)
Why are you touching SA or Input voltage at such 'low' clocks? Mine are at stock at 4.7Ghz....

People use Realbench for stability testing? LOL.
Talk to ASUS, that's what they and their reps (ie, Raja) recommend.

System agent needs a boost with high cache and high memory speeds and multiple VGAs on some chips. One of the first times it's become a relevant voltage for anything other than LN2 use.

I know.. And didn't mean to blow it off so hard. It's definitely not my preference as it doesn't give me a great idea of stability for how i use my daily driver pc (which isn't much - gaming, light photo editing and encoding).

Interesting. I was good to 4.7 with memory at 3k... Though single gpu, well 295x2, so single PCIe slot anyway.

To me, you got a good chip, but it's not like I have played with a bunch; just a few so far. But I am a bit cautious about how well these chips can clock, since I have seen 4.5 and 4.6 GHz walls, and NB scaling seems quite varied, too.

As to RealBench, I'm with you dude, but it IS what ASUS is recommending right now. It does do a fairly well-varied stability test with a bunch of different workloads, but doesn't run that long. I was just saying, that's where the confidence in it comes from, IMHO.

It's all over the map.

I only got 5.2ghz on ln2 on this thing... She's a dud in that respect. Retail edge program will net me a 5930k so we will see how that does.

If your CPU can do 4.7Ghz then thats great 90% of peoples 5930K can't i need 1.32v plus INPUT of 1.93v for only just 4.4Ghz when stressing LinX 0.6.5 i would like to see a screen shot of your system passing 150min of LinX to believe you because its hard to haha, I run a system agent of 1.12v which is needed for my memory to run @ 3000Mhz all CPUs will need a increase in system agent voltage to do so its nothing to do with the memory its the IMC.

I uninstalled AI suite and suddenly everything makes sense. I mean, every bios change, volt settings and mulipliers, stability tests and bdos. Back to normal overclocking. AI suite was the problem.

I got my answer about temps. According to the ROG site, high temps can cause instability under heavy software load.

@EarthDog I was touching those settings in a desperate attempt to make ANY overclock work. Actually, to make make anything work, I could not run Aida for 12 minutes without bdos at stock.
Now with AI suite gone I am currently testing 4.2@ 1.230v, 2133. Everything else at stock/auto except CPU Svid set to disabled because it says to do so when overclocking (I have no idea if this is necessary at such a low OC). Woke up this morning (I got the OC'ing blues) to 10 hours of Aida 64 @stock. Now into over one hour at 4.2.

What are you guys with average overclocks doing with CPU Power Phase Control and CPU Spread Spectrum? Will these settings have any impact at 4.2ghz?

Benchmark Scores Faster than yours... I'd bet on it. :)
If your CPU can do 4.7Ghz then thats great 90% of peoples 5930K can't i need 1.32v plus INPUT of 1.93v for only just 4.4Ghz when stressing LinX 0.6.5 i would like to see a screen shot of your system passing 150min of LinX to believe you because its hard to haha, I run a system agent of 1.12v which is needed for my memory to run @ 3000Mhz all CPUs will need a increase in system agent voltage to do so its nothing to do with the memory its the IMC.
Linx stable? Not sure on that... Here is the review in which 4.5Ghz is my overclocked setting, and 4.7Ghz is the 'pushing the limits' using Cinebench. If I can pass Cinebench and WPrime repeatedly, I'm not far off from stable. But I could run 4.7GHz all day through 3D's (think Vantage/11/FS which have brutal Physics/CPU sections). I think I can lower that voltage a bit too...

Its on an EVGA FTW now, perhaps later tonight when I get to sit down at the board I can post up some P95 or AIDA64 or something. But its stable for what I use it for anyway.

So with a low OC of 4.2 and no cache or mem OC the only settings I need be concerned with are vcore. If a particular vcore fails nothing else will help stabilise that multiplier.

So to high a LLC can cause instability? Can high temps cause a Bdos, 85-95c? (I stop when I see these temps, if I don't get a bdos first)

I have not been able to get stable at 4.4 because I don't have good enough cooling, I don't want to go past 1.325v cpu core at the moment.
I dropped back from 4.4 to 4.375@ 1.325v but this time with ram at 3000mhz and 125 strap. Still unstable, crash after a few minutes of linx 0.6.4 and real bench stress test test with 16 or 8gig of ram (stable with 2 hours of BF4).
These are my BIOS settings.
125x35=4.375, 3000mhz
CPU Manuel--1.325v
CPU system agent--+150 (1.034v)
CPU input voltage--1.910v
CPU LLC --6
CPU SVID support--Disabled
CPU power phase control--Extreme
CPU power duty control--Extreme
CPU current capability--140%
CPU power thermal control--120
Fixed VRM switching freq--500
Dram V--1.35
Dram SVID support--Disabled
Dram current capability--100%
Dram power phase--Standard
PCIE clock amplitude--Higher

Is it likely that I can tweak a bit more to get stable, or improve cooling, or is it simply a case of my CPU needs more volts to do these clock ratios? What do you think folks.
I would leave all at auto,

except in digi+ only these
Cpu current 130%
ram current 110%


Svid disabled,
manual 1.85v
system agent voltage 0.050 - 0.080v+ offset should be enough.


looks like 4.4ghz needs more, probably ~ 1.34 -1.35v range

I thought you would say that i can run CineBench and AIDA64 fine @ 4.6Ghz on 1.35v but as soon as i run LinX 0.6.5 or Prime95 my system will just reboot the amount of voltage need for AVX will shock you.

I never use Linx (overkill) anyway. Typically, to get p95 28.5 stable I need to add around .025v or so. So like I said, I'm in the ballpark. :)

Your right there P95 is just as good but i find that to add around 8c on top of my LinX temps lol, My chips seems to be a cow lol it will pass all types of stress tests but if i want it to pass AVX i need like 0.1 more voltage which is crap 4.4Ghz i can get to pass AVX at 1.34v but i can run 4.5Ghz for normal use Aida64, Realbench, LinX non AVX, OCCT but as soon as i start up a AVX stress ill get a reset which normally means i way off the needed voltage, I could run LinX AVX for a hour fine once it got up to around 1 hour 20 minutes ill get a BSOD so i kept increase the voltage until it passed, These CPU are really odd to overclock.

I think so too.

Prime95 or any AVX stress tool I need stupid amounts of voltage as I don't use any think AVX and if I do it will never put full load on my system, I don't tune using it I use linx 0.6.4 and aida64 and test for 6+ hours.




UPDATE!!!!

Well LLC on auto isn't Level 9 for me i did a quick test with VCCIN set to 1.85v Also if you set auto in the bios and change it in Ai Suite Level 9 becomes the auto setting, You have to select a Level in the bios i selected Level 6 here's what i found.


LLC Auto vdroop = 1.792v - 1.808v ( Level 6 )
LLC Level 9 vdroop = 1.856v - 1.872v ( fluctuation )
LLC Level 8 vdroop = 1.840v - 1.856v ( fluctuation )
LLC Level 7 vdroop = 1.792v - 1.808v - 1.824v ( fluctuation )
LLC Level 6 vdroop = 1.776v - 1.792v - 1.808v ( fluctuation )
LLC Level 5 vdroop = 1.776v - 1.792v ( fluctuation )
LLC Level 4 vdroop = 1.760v - 1.776v ( fluctuation )
LLC Level 3 vdroop = 1.728v - 1.744v ( fluctuation )
LLC Level 2 vdroop = 1.712v - 1.728v ( fluctuation )
LLC Level 1 vdroop = 1.696v - 1.712v ( fluctuation )

LCC doesn't seem to give much Vboost on my system even on LV9 i would say its safe to run it on LV8 as its very close to what you set in your bios.

I just ran a quick 5 minutes LinX 0.6.5 AVX test with the above LLCs Now my system isn't stable running LinX even for 5 minutes i normally get a BSOD and seems like LLC was the problem after setting LLC to Level 8 i was able to run LinX for 5 minutes the LLC settings below all failed.

No idea but AVX now fails again with a BSOD when reusing the settings it passed on just before .

0.016v fluctuation at every LLC setting. Look at this screen capture I just took.
0.016.png
This is LLC 7, also 0.016v fluctuation. What ever LLC I use I get 3 readings. Usually the lowest reading is the most prevalent, but sometimes it's the middle one. Will test now to see if different LLC has any effect on whether the lowest or middle number is used the most during stress.
