I-7 6700k Overclocking

post #1 of 11
Thread Starter 
Hey all,

I've got a 6700k and msi z170a krait gaming mobo, a bit disappointing in the quality of the mobo but thas a different story and 16G of G.Skill Trident at 3300, love these guys and their RAM.

So I've OCed 6700k to 4.5 at 1.28v. Had it full stable on over 24hr run on Prime 95 and like a 12 hr run in IBT. Was very happy with results.

This is not a gaming rig. It was designed to run Innovyze Infoworks ICM modeling software for my boss. I ran a test to see how much faster this set up works and got a blue screen some 30 mins into the process. After looking at some things and rerunning the simulation, I've set the OC to stock and ran it and everything seemed fine. Well the next step figured would be to add more voltage. I ended up going to 1.32v, which was stock 4.0 clock. Everything started to work like a charm. Then a week later on a different simulation had that bad blue screen again..... I didn't have the time to tweak with the voltage so I just set it to auto and the mobo bumped the voltage to 1.4, fine w/e lets see what you got. I've started the simulation that caused a crash and went home, it was a Friday after-all. Everything seemed to go well and temps hit 66C from previous 61C. I've haven't touched it since.

I've only meddled with the voltage and maybe changed a couple settings, as I almost never change anything else as I've gotten stable results and happy this way all the time. Now is there any pointers I might be able to get to lower the voltage to shave down the temps?

hello have you tried running Bluescren view or who crashed app..after each blue sreen.it will tell you ecatly the cause of the crash....

also try a HARD RESET of the board..remove the cmos bat after removing all power etc..internally and externally...leave it that way for 20min...the reconnect it all and load defualt bios settings...see if it helps...dont OC anything untill its been atleast a few weeks of stability:D

Bluescreen view, How I've never came across this before? D:

Didn't really have a few weeks to wait to figure out if everything was stable. But I did stress out the system on defaults for two days before OCing. And everything worked good on the OC until Infowork ICM ran a specific simulation. It ran others just fine. The program pretty much utilizes everything the CPU can give it. That's why I think it is the cause of it, plus it's the only thing that runs, unless excel can cause a blue screen.

I'll give it a shot of hard reset. If anything I'll just let it have its way with 1.4v and get a bit better cooler.

i do a lot of repairs from old to new school..these apps have saved alot of people ALOT of money...cause usually they get told they MUST buy new hardware when it fact its a software issues not always hardware...
quick tip- never oc a system within its 1st month of buying it..if something busts..your out of luck with warranties for rma...most brands have reps these days eerywhere...so posting live that you OCed the
setup and now its wonky....wont help you at all:thumb:
just hard reset the thing...it helps alot

ooo thanks for the links.
Haven't had a chance to take a look at bosses PC, but there was no complains from her. That means that my theory might be right. Just cause prime95 and IBT says it's stable it doesn't mean that they were able stress every nook and cranny in the CPU. If only i had the knowledge to understand how infoworks ICM actually works.

My CPUs get OCed almost instantly biggrin.gif, a month is too long for the fun, not to mention that is the exchange period of Microcenter. Plus I don't push things to the limit. In this case I only took the 6700k to 4.5.

You got me curious tho, how can one mess up an OC these days? Everything is made so easy. Not like back in the day where mobos had like 3 options set your clock speed, voltage and play around with the RAM setting to go stable.
Many motherboards do all the heavy lifting for you, all you really need to do is play around with the voltage as the stock voltage the mobo gives for your overclock is always too high, well maybe not in my case right now:thumbsdow Unless you going to the ceiling of your CPU or you don't have proper cooling. I don't see all that much room for mess up.

Also for all those company reps that linger around posts as you say.
Dear Corsair,
I've been waiting for well over a year for my replacement for my broken Corsair Link cooling node, that worked for some 3-4 months. My ticket number is 6494280. Haven't bought a Corsair product since, even thought half my stuff is usually them.

What is the cpu operation temperature? I am very surprised it crashes at that speed and voltage.

You and me both.
Lets see when I had it at 4.5 and 1.32V max temps was 61C while running Infoworks ICM Simulation Engine. Prime95 Max was 73C IBT had it about the same 1 or 2 degrees higher. Don't remember the temps at 1.28v.
At the Current 1.4v which so far been all stable with ICM, max temp it hit was 68C. I image Prime95 would hit at 80C.
Idle temps are in the 20s.

Can be caused by memory (& cache speed) too. The error code could help.

Hello

Sound like IMC instability to me.. Try the stock setting and keep the memory at 2133mhz.. for 3300mhz you need to change the system agent to 1.200v to be stable at high memory freq..
