Crash - Overclocking CPU with XMP enabled

[oversere]

Hi everyone,

I’ve recently bought a new PC, and I’m having some issues with it, thought you might help.

MOBO: MSI Z170A Gaming M3
CPU: i5 6600K @ 3.5 GHz
RAM: G.Skill RipJaws DDR4-3200

The issue is the following:

Right now on stock settings everything works fine, but I wanted to do some overclocking on the CPU and enable the XMP profile.

Case:
a) If I overclock the CPU it runs @ 4.5 GHz with no problem. (CPU ratio: 35 -> 45)

b) If I enable XMP, the RAM runs @ 3200 MHz with no problem. (XMP Enabled)

c) If I enable XMP, and do any tweaking on the CPU, the machine will not boot. It just keeps restarting, until I power it off and reset the BIOS settings.


Any input will be much appreciated.


Thank you for your help,
Cheers

Do you have the latest BIOS? Should be able to OC while XMP is enabled

 

[oversere]

Yes, that was the first thing I did.

 

[Tradesman1]

Could try increasing CPU voltage, not really sure, I don't build on MSI due to their poor QC, (not a fan of their BIOS s either), but have worked with a few Asus Z170s, and a couple/three each Rock and GB mobos and no problems running the DRAM and OC independent of each other

 

[oversere]

I saw a videos on youtube, doing overclocking and enabling XMP on an Asus Z170 ProGaming MOBO with no trouble what so ever (no voltage change required), but when I do the same on my system, I can only get one part running smoothly.

It's a shame, because that was the reason I bought the 6600K in the first place, even got a nice Dark Rock 3 to cool it.

I will do some tests tomorrow.
Thank you.

Each 6600K is individual, you may need a vCore (CPU) voltage increase

 

[oversere]

Well, this went poorly. I’ve increased the vCore to 1.350 but I’m still unable to get it working.
Can’t even get to BIOS, the PC just won’t start. The control LED on the MOBO stops at DRAM and than cuts off the power.

On the other hand, I’ve learned that I can do the CPU OC from the software that MSI provided with the MOBO called Command Centre.
So right now I boot up on CPU stock speed with XMP turned on, and then if I want some more juice I just crank up the core ration in the software.

It’s something.

Sounds like they need some more work on the BIOS (which is common with the new Z170s)

05.06.2016. - Just a quick update.

After updating to the latest BIOS version (A.60), I was finally able to overclock my CPU with XMP enabled, without experiencing any crashes.

Guess the BIOS needed some more work, and now it all works flawlessly.

Cheers 😀

Thanks for the update, sounds like they took their time on it 😉

Dude, How did you oc ram to 3200 when your cpu support 1866/2133-1333/1600 ??

 

[Tradesman1]

6600K is native to DDR4 2133, most 6600K can easily run up through about 2800 sticks at stock (some higher), generally 3000 and up is where a CPU OC may be required

 

[oversere]

@Mohamed Blat, the base frequency is 2133 MHz for every DDR4 memory kit (this enables you to boot your PC without having any issues), that's where Extreme Memory Profile (XMP) comes in to play.

Cheers.

Hey i also have Gskill DDR4 RAM with COAX speed of 2400MHz which is set by default and XMP RAM speed of 3200MHz. I use the overclock value of 3200MHz for my ram anyways. My cpu is the intel 5820K CPU with default clock of 3.3GHz and gaming overclock speed of 3.6GHz. I use the gaming overclock and not the default one. My reference clock is set to 100MHz and the cpu voltage is default. I also have GTX 980 MSI version with core boost to: 200MHz and memory speed 170MHz boost. The fan spinning for cpu water cooler and GPU of 100 Percent. I have a samsung 850 evo pro with 520MB/s.

I use MSI x99s gaming 7 motherboard which support XMP AND overclock genie feature. The CPU and XMP are on but i also experiance many game crashes, for eg. titan fall freezes on the main menu when it first loads. and battlefield 4 stops working online when i enter online mode. When i press the W key, the game freezes and the pc turns off maybe because my cpu and ram doesn't handle it.

The gpu is also overclocked and im sure its okay to do that because our msi motherboards are meant to be USED THAT WAY. They are supposed to be used in that manner


What i want to do is, use XMP and overclock of my intel 5820K cpu to 3.6GHz same time as XMP. I could not do it as well because my PC crashes. It freezes for 5 seconds then, the pc shuts down. I updated my BIOS to latest version but still i have the problem. The FSB or reference clock is set to 100MHz . Should i change it? The cpu voltage is max and i cant change it. My power supply is 840Wats power supply. I have 3 dvd drives installed on my pc, 4 times DDR4 gskill 8GB memory modules on my MSI X99s gaming 7 motherboard and my GTX 980 Video card msi version. I dont know what causes the crash. I know m

 

[oversere]

@Ragahv, I would suggest that you set everything back to stock clocks, test if everything is stable with stock settings and no XMP.
If the games crash even at stock, consider reinstalling game, drivers.

Only after you made sure, it all works at stock, start overclocking.

PS: Keep the BCLK (CPU Base Clock) @ 100 MHz, change only the multiplier.

Good luck 😉

 

[Ragahv]

Yes, thanks for the reply.

I have understood what you are trying to tell me. If i revert back to stock settings, i will get normal PC operation while playing all my games. However i have done that and i have noticed the games run well than overclocking. The MB is made for overclocking. So is the CPU, ram and gpu. I overclock using the multiplyer . At the moment its 3.3GHz. Now its 4.0GHz

You probably need to give it a bit more voltage. The 5820K's I've worked with default to 0.95V and that's not enough to get very far at all. I would start at 1.1 and see how far that gets you. If you're not satisfied, you can go up in small steps with voltage and try again, up to a max of 1.3V.

 

[Ragahv]

So your saying that, increasing the voltage parameter also increases the multiplyer or the speed of the processor?

I know what voltage is - The cpu needs it but i thought if the voltage was ever exceeded it would cause the cpu to go bad/smoke - do you think if i exceed the voltage limit cpu can catch fire or have smoke from it? When wud a cpu smoke?

Also, what if i only change the cpu multiplier? What if i leave the V at 0.95 and OC at 4.0GHz. Are you saying if i want to OC at 4.0 GHz i would need to apply more voltage? Im scaared that will damage the cpu. What V do you think i need in order to OC at 4.0GHz. NO one has done this to their 5820K cpu without a water cooler. Since i have a water cooler, im keen on doing so. I never knew that applying voltage would improve speed of cpu.

The highest stock voltage that the Haswell architecture is made to run at by Intel is around 1.25-1.27V in the case of the 4790K. The stock voltage is higher because that CPU turbo's to 4.4GHz vs 3.6GHz in the case of the 5820K. It's pretty fair to assume that voltages below 1.3 are safe as long as heat is controlled. There's anecdotal evidence that degradation is a concern at voltages starting above that point. Mild degradation causes the CPU to lose stability at overclocked speeds. Severe degradation can render the CPU unstable at stock speeds or even completely dead. The stories of people degrading their CPU's are few and far between in the 1.3X range, but they are quite common in the 1.4X range.

 

[oversere]

@Ragahv, increasing the voltage parameter DOESN'T increases the multiplier or the speed of the processor. Voltage is for stability reasons. If you want the CPU to run faster, you need to give him more power.

If you exceeded the voltage, the PC will turn off, it will not catch on fire 😀

When I did my OC, I let the BIOS handle the voltage automatically, but overclocking is a process, you rise the clock speed in increments. Then boot your system, do some benchmarks, stress tests, monitor CPU voltage with CPU-Z(free software).
If everything is stable, and the PC doesn't crash, go back to the BIOS and rise the clock another increment, repeat the testing process. Do this until you reach a sweet spot.

Cheers 😉

I fried a 5820 using 1.3v. Lasted about 6 months.

What motherboard did you have it in? If it's an ASUS X99 board, then that's why. I have to keep mine below 1.25V, or I end up with dead boards and dead CPUs. 3 of each in less than a year. If not ASUS, I'd like to know the details. MB, clock speed, input voltage and cache voltage.
