i7-5820k CPU on an Asus x99-a Mobo

31crzy · Jan 9, 2017

So I'm super green thumbs when it comes to overclocking. I know absolutely nothing about it except that it can help boost the performance of your PC when gaming and doing other things. My questions is this, how do I overclock my CPU to a better speed instead of 3.3 so I can run games better. I've checked out a few videos on youtube, but I can't tell if the settings are actually working or not. I'll leave a current list of my specs below.

System Specs:

Case: Corsair Graphite Series 760T CC-9011074-WW White Full Tower Windowed Case
Mobo: ASUS X99-A/USB 3.1 LGA 2011-v3 Intel X99
GPU: GIGABYTE GeForce GTX 970 4GB G1 GAMING OC EDITION
CPU: Intel Core i7-5820K Haswell-E 6-Core 3.3 GHz
PSU: CORSAIR HXi HX1000i 80 PLUS PLATINUM Certified Full Modular Power Supply
RAM: CORSAIR Vengeance LPX 32gb 288-Pin DDR4 SDRAM DDR4 2133
Drive 1: Seagate Desktop SSHD ST4000DX001 4TB 64MB Cache SATA 6.0Gb/s 3.5" Solid State Hybrid Drive Bare Drive
Drive 2: Kingston 128GB SSD --- running games from this drive ---
CPU Cooler: Corsair Hydro Series H110i GT High Performance Water / Liquid CPU Cooler

I'm currently playing a lot of DayZ Standalone, but I'm having some FPS drops in game when I'm around towns and cities. My team says that it happens to everyone, but I believe that it can be fixed by upping my CPU speed a bit more.

I'm also running Windows 7 home premium at this current time so I'm only able to use 16gigs of my RAM

The Haswell information basically applies to Haswell-E in terms of voltage limits and major settings.

Every CPU is a little different, but you should be able to get quite a bit more out of it.

If you want a quick test to see the limits, your motherboard likely has some built in OC tuning utilities.

No, voltages aren't the same between Haswell and Haswell E......Haswell E runs much hotter than the mainstream i7s.

Depending on your cooling, you can get these processors up there quite a ways. I had the same motherboard and processor, and ran mine daily at 4.3 @ 1.249v.

This thread has a ton of good info on the Haswell E processors.

My understanding is the voltages are the same. Yes the HEDT processors can pull more current and thus more heat, but the H110 should be more than enough.

Even the chart you linked too has most of the air cooling setups hovering around 1.3 which is around the safe maximum for the 22nm process it is built on. (Saw a 2.06 in there, and not under LN2 cooling, hopefully a typo)

It takes my venerable 4770k nearly 1.3 volts to handle 4.3Ghz. I can run it at 4.5Ghz, but it does take 1.35 volts, and nearly 100C even with high end water cooling. Not comfortable for day to day.

Vellinious :

I'd love to be able to get up to at least 4.0 but IDK how to tweek the settings to get my system to run that way. Basically I'm asking for a cheat sheet so I can fill the system settings into the BIOS and then apply them. I'd love to learn more about overclocking but IDK where to start. Also like I said, Win7 is throttling my RAM

31crzy :

This is a good place to start. Then, get in that forum link I posted earlier, and read / ask questions.

The best thing you can do, obviously, is just read. Get familiar with your motherboard's bios. Nobody is going to be able to tell you which settings to tweak to get your specific processor stable at your target clocks. They'll be able to ballpark it, but to tune it so it runs properly, that's going to be on you and you alone. You're going to have to do some trial and error...test settings, run short stability tests to get things close, monitoring temps and voltages with HW Monitor or some other good monitoring software, and see where it gets you.

@Eximo....if you're pushing toward 100c on 1.35v with a 4770 at 4.5 with "high end watercooling", you're doing it wrong.

As soon as I take the voltage up past 1.31 or so the power draw shoots up enormously. If I were to give my CPU a grade it would be a C-. There were plenty worse 4670k and 4770k then mine at the time, some failing to reach 4.1Ghz. The only thing I never did to it was de-lid and re-apply thermal compound, which probably would have taken care of most of it.

HEDT processors are soldered to their heatspreader, so they have a nice advantage there. And on the Haswell refresh they basically used a better compound or better quality control and took care or most of the problem. I was very tempted to pick up an i7-4790k, which could beat my processor at stock settings.

Not to worry, I have a 7700k sitting on my desk waiting on the motherboard to arrive.
