Quick Overclocking Guide for EVGA X79!

I feel like this overclocking guide needs to be updated. I'd love to know what revision OP was using because it seems after revision 039, no OC works.

What revision should I use?
What settings (BCLK, CPU control voltage, CPU multiplier)?

I currently can get my 3820 to 4.3 GHz (simply by increasing the multiplier to 43). I once was able to get it to 4.5 by setting BCLK multiplier to 1.25 and leaving the CPU multiplier at 36.

I'm telling you guys, Kingpin laid it out very simply.

I'm using his model to go by except the memory timings. I have to leave mine on auto for the mem to run at 2400mhz.

50% vdroop keeps my volts around 1.45 - 1.46

I would say yes to that until you find your max OC. Then I would go back and find a percentage of vdrop that works for you as well. Other wise your Vcore is going to spike every time you load it.

Hey guys. I would disable Vdroop, enable PLL CPU volt overide.

set the Vcore to fixed voltage. then Start with 1280mv then work your way up to a stable voltage.

I have varied my voltages and found that I can run 1.28 to 1.32
stable.

Those higher volts you guys are trying is going to destroy your CPU or motherboard and even worse both. even when I was on air and heat sink I would only be at around 48-55c under load @ 4.6ghz 1.32v

I'll check out that vid when I don't have to multi-task between work, this, and grad school! Ha!

Interesting, discovery just now... I turned Vdroop back on and enabled Internal PLL override and set the Vcore to fixed 1.425 and it's now perfectly stable at 42x, 66ºC, 1.376v Vcore at load.

140 GFlops in LinX at 4.7 seconds a run with just 6 threads. Very nice.

Before I had Vdroop off, PLL to 1.9v, and Vcore at 1.4v and it was drawing up to 1.482v and temps were in the mid-70s at 42x multi and it would crash/restart within seconds. I thought I had a poor chip for a second but it appears that simply reenabling a few things really helps. Thumbs up to this mobo for making OCing even easier than originally thought.

--EDIT--

So it appears doing the above with Vcore set to 1475mv and PLL set to 1.9 does the trick at 46x for me when leaving Vdroop on and turning on Internal PLL Override.

LinX 6 thread - 150+ GFlops
LinX 12 thread - 128+ GFlops

I've been using the Intel Spec all along, but not the PLL override.

I will try that too, Thanks!

Working at 38X125=4.75G Just passed Intel Burn Test on High setting 7 run set. I may have my 38X OC back, Thanks Again.

I'm running 4.6ghz @ 1.32v
Idle temp 28-30c and under full load 35-40c

Could you post pics of your Bios settings, similar to HoracioArcondo's above.

Need a template for the X79 boards. I would love to see some of the settings everyone is running.

Re:Quick Overclocking Guide for EVGA X79! (MhzManiac)

I tried taking the Vcore down to 3.3v with various vdrops and also no vdroop. I could not get it to pass Intel Burn Test on high setting without killing the vdroop and raising vcore to 3.56v. Under heavy load is rises to 4.1v and drops to 3.56v at idle. When I was using the Intel Spec vdroop, it would stay steady at 4.1 at all loads. I will try this config for now and look at getting an H100 or H110 setup.

By the way, nice looking rig. I need to enlarge the hole in the rear plate of my case so I can hide my cables like that.

How is your H50 setup configured? Your sig makes it look like more than one. Mine is just modified push/pull.

Never mind, I see you have an H110 on the cpu.

Yah I'm using a H110 for the CPU. The Titans have H50's on their GPU's

Got yourself a little toaster there with that high of Vcore voltage. I keep my 3820 at 1.41 volts with 50% vdroop at 4.625 G. Never goes above 1.43.

My max temp under constant load is 72c, what temps are you getting?

Do anyone have a setting that can help me overclock my X79 Classify intel I7 3930 processor with a EVGA GPU 660 FTW Signture 2. I have try several without any luck. Any help would be greatly appreciated.

thanks,

You need EIST enabled for throttling.

i have no option for offset mode on cpu vcore, only auto or fixed?, all cstates enabled but cpu stays fixed @ 4.7 and vcore stays fixed as well, i wanted it to throttle down while idling?

Sadly this overclocking method is far off, and does not work at all. Everything I have tried just resets the motherboard -- and Windows 7 never see's the overclock on top of it. Not even able to take full advantage of my memory, which kinda erks me.

Sorry I purchased this motherboard. Between its overclocking lack-luster and the lovely Check-sum error after updating the BIOS (from Windows or DOS) has pretty much told me: this is the last EVGA motherboard I will purchase. I love EVGA, but someone screwed the pooch on this board.

Also, I am not "Danny......" on this account. I have no idea why my account shows me as someone else when I log into my EVGA account.

EDIT/UPDATE: Sadly all of the 3.0 USB connectors on the back of the motherboard have just died. Nail in the coffin: my last EVGA motherboard purchase. Really shocked at how bad EVGA has gotten :/

I've been able to get 4.2 without changing any settings. I can't seem to,get my ram (rip jaws 2133+) past 1867. Any tips? Running a 3930.

As was pointrd out to me the BCLK has to be 100, 1.25 and one other anything will make you lose ports, Nic etc. I HOPE there is a Bios Fix for this ONE of these days...

I'm currently @4.5Ghz HT Off with my Classy and my 3960X.
Before i was with all power saving features set to "DISABLE" and i was rocksolid, now i turned on "C1E" and "EIST" because i want that the frequency goes down when I'm in IDLE. The system looks stable (like before), should i have many problems with these features turned OFF?

Another thing that i saw.. i tried to work with the BCLK and the BCLK Ratio. For example i tried with the 112.5Mhz frequency (BCLK Ratio = 1.25x). Everything was stable except that i lose my USB 3.0 ports. I don't know if the problem was the 'strange' BCLK frequency or the ram frequency (i also pushed them up for that test, a bit over them specs). When i came back to my settings (4.5Ghz HT OFF BCLK 125Mhz) USB 3.0 ports returned to work.

Thanks VagueRant and mwparrish! I think I'm finally getting somewhere.

(Now if only the 680's would show up as in stock long enough for me to order. Although I really want two of them.)

The only thing that should be enabled on that page is Turbo. Without Turbo enabled... nothing happens.

Leave the individual core multiplier alone on that page and set it on the main Overclocking page. This has worked without issue since BIOS 030.

Re:Quick Overclocking Guide for EVGA X79! (VagueRant)

With C-states disabled the 3930 will not go past 35, from its default 32 multiplier, which is the all core running turbo speed. When you enter in the multiplier manually I assume it is essentially turning off the incremental turbo speeds to run at a set speed. If you have C-states disabled then Windows would be what is lowering your multiplier and voltage. Just go into Power Options and make sure Minimum Processor State is set at 100%.

(Power Options -> Change Plan Settings -> Change Advanced Power Settings -> Processor Power Management -> Minimum Processor State = 100%)

Ok..., I've got Speedstep disabled and I've got the multiplier for my CPU set to 36. Yet, in Eleet, it shows my CPU running at 1200 mhz unless the computer is actively doing something. I thought disabling Speedstep would keep it at 3.6 ghz.

Also when running benchmarks, it seems to be capped at 3.6 ghz and doesn't boost to 3.8 ghz as is listed for the max turbo speed for my 3930K.

How does one keep the CPU from downclocking and how does one raise the boosted, turbo speed on an EVGA X79 Classified with BIOS 37?

Answers are probably incredibly simple for the experts here, but the BIOS on the X79 boards seem to have an order of magnitude greater options and choices compared to my old X58 build.

Thanks for any help offered!

I've probably missed it..., but how do I turn off the Intel Speedstep in BIOS 37?

Thanks!

It's under:
Overclocking -> CPU Configuration -> CPU Power Management Configuration

EIST Enabled/Disabled

Thank you very much! (The old eyeballs aren't quite what they used to be.)
