Hello everyone,

First of all, I don't have proper knowledge on OC'ing CPUs but then I try to keep my CPU at 4.5GHz and I am having troubles and seeking advice about settings. I checked many sites and comments about this but could not resolve the issue.

I set CPU to run at 4 GHz and there is virtually no issues but when I try to run it on 4.5 Ghz problems start as:
- Computer randomly freezes on load or idling with constant "Grrrrrrrrrrr" on speakers and screen stays frozen on last frame until I reset PC. No black screen or any kind of Bios/OS error.
- This happens randomly, like 5min after boot or 2 hours later, idle or on load.


If I set CPU ratio to 45 and leave DRAM frequency Auto and XMP off, computer gives OC failure on restart, If I set XMP auto, it boots but freezing occurs after any random time. I tried all memory settings possible and it didn't help with the freezing.

I tried to increase CPU voltage close to 1.3V and it didn't resolve the freezing problem. I have also a feeling that the whole problem is something to do with the Memory, I am using Kingston Fury DDR4, 4X4, Kit of 4, in quad channel mode. Very rarely in a year, sometimes one of these Rams lose connection to system and I see 12GB reported (3 of 8 Ram slots usage) instead of 16GB, no error on quad channel configuration, I reseat all rams and it fixes the issue.

If you guys could help me with settings in the image I will be very grateful to keep it running on 4.5Ghz without freezing.

I am cooling CPU with an Arctic Freezer 360 CLC, it's running very cool.

Thank you for reading. Settings in images are for Simple mode, If I switch to Advanced there are more settings enabled.

My old 5820K need 1.38v for 4.5ghz. And its was quite picky on temps as well.
If it went over 80c it would become unstable.

The first thing you need to do is get a stable base line for everything.
So drop speeds back to something like 4.2ghz and run though a few stress tests and make sure it all passes that.
Then dont touch any of the memory settings and start working your way up from there.

If you are just gaming I would disable hyper-threading so you aren't asking the cpu to function in a way you don't require and by doing so temps will drop.

my 5820k runs at 4.5 1.35v

You need more core voltage. Start at 1.35V

Hi,
Indeed it might just be the ram
I had corsair dominator 2666C15 4x4gb kit
Corsair used micron memory chips which hate my board it always drops one stick off the map causing bsod.... usually C_1 dimm but not exclusive if I moved that stick to another dimm it dropped off the other dimm slot too

RMA'ed the kit next kit did the exact same thing.

I'm using trident z 3200C14 4x8gb kit now samsung memory chips and works so go figure lol board is only really compatible for 2400 but 3200 is running without issue for close to 6 months or more can't really remember.

Either way 1.3v should be enough pretty much what my 5930k will do it at with various different way to dial it in/ manual mode/ adaptive 0.001 and 1.3v haven't figured out offset mode though

I'm sure the ram dropping off is pretty much why the clocks bork but yeah 3.5v is what I read as limit but if you can cool it I doubt it really matters.
On asus boards cache voltage and possibly vccio cpu 1.05 voltage has been frying them
New bios shoots vccio cpu 1.05 voltage to 1.25v when reading say no more than 1.15v should be passed
Cache voltage absolutely less than 1.2v far less I try to keep it at no more than 1.17v at 40 max cache.\

Use thaiphoon burner to see what memory they used I'll guess micron or hynix.

Uh, what? The vast majority of 6 core Ivy Bridge-E chips are not stable at 4.5Ghz/1.3V. That's clearly the most likely reason he's unstable, not memory chips.

I'm stable at 4.5GHz and 1.28 =)

Been running like this for years now.

The best part is, I also have C-states and speed step enabled. It auto clocks down to 1.2GHz and 0.75V at idle.

I think it's more a function of this power supply and this motherboard. I had this chip in a different board and couldn't hit 4.5 no matter what I did.

Once I finally got it stable on fixed voltage, I swapped to adaptive with an additional 0.02v everywhere and slowly dropped core voltage down from 1.35 a little bit each week. Around 1.25 is where it started to get unstable, so I bumped it up little by little and eventually stopped at what it is now. I haven't had any unexplained crashes in a very long time.

Hello guys,

I tried as @bmgjet suggested and anything above 4 Ghz with dynamic cpu ratio mode is crashing. Then I saw an option fixed cpu ratio mod and there is no problems so far,
@ThrashZone I think that makes sense because I also have a similar memory kit which is acting in a similar way dropping one of the sticks, only difference there is no bsod or error. KHX2400C15D4/4G kit of 4. Just that this happens very rarely.

I have a feeling this CPU/motherboard/memory combo does not like to be overclocked on dynamic cpu ratio like yours. On fixed mode it is 1.275mv on 4.5Ghz.



I still want to have a proper non-crashing dynamic mode (speedstep and c-states enabled) so CPU can lower its speeds when not needed. But this does not seem possible voltages under 1.3?

Thank you for answers, I appreciate all.

Your aim is too high IMO, getting 4.5 GHz on Haswell architecture is not an easy feat especially if it is an older batch or anything other than 4790k and 4690k. You have to start low so you know the potential of your chip, as the quality of production between chips varies.
I had two 5820ks and both coudn't reliably do 4.5 GHz at anything below 1.35v (OCCT 4.4.1).
I recommend to start stabilizing at 4.2 GHz and using a reasonable stress test such as OCCT 4.4.1 large data set. Avoid anything newer than 4.4.1 though as that puts unrealistic load on the CPU.

http://www.ocbase.com/download/OCCTPT4.4.1.exe

First stabilize the core at default ram clock, then after you reach confidence that it is stable, stabilize the OC with XMP.

Hmmm, now I ma thinking my 5820k at 4.3ghz and 1.22v is pretty good. Never really pushed it more.

Hi,
I don't know about that but silicon lottery is real :)

I'd start with adjusting system input and system agent and use load line calibration
Normal start would be llc 7 possibly 6 "8 really but I'm too chicken for that need more droop" don't get greedy just go with optimize and 120% cpu capability
Set input to 1.91 possibly 1.92v
Get system agent adjusted to 1.1v+ a little I've used offset +0.195 I believe gets it there or a tad above.

Tie down both the vccio voltages to their default or standard of 1.05
Limit the cache with 24 min and 38 max and offset mode of +0.175 should work just fine.

Should be able to get 4.5 temperature allowing.

From ROG forum hasswell-e oc'ing guide

Proper VCCIN voltage is dependant on several settings such as CPU speed and voltage, cache speed and voltage
and to a lesser extent SA and IO voltages. Though DRAM voltage is external to the processor the amount of
installed ram, speed and timings can also have an influence on the needed VCCIN voltage because of loading.

The following is assuming active cooling across the VRM section of the motherboard. Set VCCIN to 1.90V
and LLC to Level 8. Make the necessary adjustments for stability at your desired CPU, cache and memory
speeds and timings. Once stability is found slightly lower VCORE and increase VCCIN in 0.010V steps.
If still stable continue lowering VCORE, raising VCCIN and testing for stability until VCORE cannot
be lowered any further while remaining stable or 1.95V VCCIN is reached.

If increasing VCCIN from 1.90V does not allow a lower VCORE VCCIN may already be higher than needed.
Lower VCCIN in 0.010V steps while testing for stability. Once instability is reached increase VCCIN
at least 0.010V.

Setting LLC to Level 8 pretty much locks the VCCIN voltage to the same value regardless of load.
There is at times an approximate 0.020V droop but the droop and recovery happens quick enough that
it is likely not to be seen by software. If the VCCIN voltage is at a low enough value LLC levels
from 5 to 7 can be used. The lower the LLC level is the more voltage droop will increase. Moving
from LLC Level 8 to a lower setting will require increasing the VCCIN voltage. Keep in mind that
droop is a good thing as it helps guard against overshoot during loading. But the amount of droop
needs to be balanced against the required set VCCIN voltage.

Guys, thanks for answers,

I am needing highest single thread/core speed possible, I can disable some of cores in that matter. could you help me about how can I do this?

I saw some options in BIOS that disables core and so on but not sure what to do.

Disable hyper threading, That will turn it into a pure 6 core cpu and half the power and temp while only losing about 30% multi-thread performance.
Push as much voltage as you can cool.

Hi,
You can also disable multicore enhancement
If you have a bad core or two just use by core oc'ing and tone down that core to a lower clock and lower voltage.
But you're dealing with a asrock board if not mistaken oops nope msi :eek:
