help! First overclock (i7 10700K) and RAM overclock

[EspinalAndres]

Greetings,

I just got my first K processor (i7 10700k), I already did an overclock by replicating this video

Is this ok?

 

I change:

• CPU ratio: all core.
• CPU ratio: 50
• CPU ratio mode: Dynamic mode.
• CPU ratio offset AVX: 0.
• Ring ratio 48.
• CPU base clock apply mode: next boot.
• CPU core voltage: 1.33.
• CPU SA Voltage: 1.2
• CPI IO Voltage: 1.2
• DRAM voltage: 1.35 (Overclocked RAM from 2666 (16,16,16) to 3200 (18,19,19,39) ¿Is it better?
• CPU loadline calibration control: Mode 3
• Long duration powe limit: 4096W
• Long duration Mantained: 128s
• Short duration Power limit: 4096W

 

But doing a Prime 95 I get 100C° on CPU and 100 C° on "MOS" (which I suposse is the mosfets?)  after 5 minutes:

 

What can I do?

Thank you.

Every GOOD video I've ever watched on the topic says to NOT COPY other peoples data like that.

You wont Find your own system weaknesses over time doing someone elses work on a different piece of silicon.

 

Clearly too hot at that voltage and frequency (+fan curves)

Start dropping voltage for heat reduction..,then drop clocks when its not stable at lower voltages

What values Do i need to start moving? I dont know how to

[SkilledRebuilds]

Well even without looking at frequency..

The voltage is too great.

 

 

You want to see where your cooling handles certain voltage values..so...

Further more thinking about it...

Id just start way lower at Default Everything

Then. .Where does Auto Voltage land  ?

If using Multicore enhancment or FullTurbo unlock,what is its voltage requirment..?

More DATA YOU KNOW ON YOUR OWN SYSTEM.

The easier it is to dial it in..

This will take time.

Don't bother if you don't have time.

Watch GUIDES without APPLYING anything.

Learn from similar systems but don't use their values, but you're own.

[EspinalAndres]

Is it ok to start just with CPU ratio, until it doesn´t boot.

Then I'd start to increment the voltage?

Or is it necessary to move more settings?

[HoneyBadger84]

Is your RAM set to XMP?  What RAM are you using?  Those timings are VERY loose for 3200MHz unless you have a kit that can't hit 3200MHz at better timings... as a for instance, the 3200MHz version of my RAM has CL14-14-14 timings @ 1.35V.  CL18 @ 3200MHz is cray cray imo.

Also, I highly recommend doing any RAM overclocking LAST, after you've found your happy stable spot on your CPU overclock testing.  It is the hardest part of any overclock if you really wanna go hard on getting your RAM fast & tight timings.

Is there any airflow at all over your VRMs?  Some airflow is better than none.  Where and what direction is your CPU radiator mounted in?

A picture of your system's insides would be very helpful.

 

If you want an idea of how crazy I am on "giving stuff good airflow", witness:

 

That 200mm monster moves quite a bit of air over the VRMs while being relatively silent at 800RPM, and the GPU radiator intake fan is "above" them, to pull any hot air out quicker.

 

Edit: I would not push your CPU any further until you get your temperatures figured out, VRMs running at that temp readout is on the borderline of unsafe.

Hello, my ram is set to XMP, this is my ram: https://www.xpg.com/es/feature/552/ (2666Ghz Cl 16-18-18), currently at 3200Ghz (18,19,19,39).

 

My current settings are:

• CPU ratio: all core.
• CPU ratio: 51
• CPU ratio mode: Dynamic mode.
• Voltages override.
• Ring ratio 47.
• CPU core voltage: 1.32.
• CPU loadline calibration control: Mode 4

Everything else is auto, I get like 60° after two minutes of Prime 95, but after 3 minutes it goes up to 80 and crashes.

Currently the case is open both sides and front also, two fans 120mm as exost (one up, one on the back) and one AIO 240mm as intake.

 

What can I do in order not to crash? It crashes on Prime 95 but on Cinebench is ok and also in PUBG is completely stable (I played like 2 hours).

Thanks.

What version of prime95 and was it small FFTs? Modern prime95 with avx and small FFTs is very hot and some would argue it needs too much voltage to be worth it. You could probably go above 80 on synthetics. Try upping the voltage by .005 until it is stable.

 

And just to be clear, is 3200 the xmp speed, or is it 2666?

Hi, is version 29.4.

I just do this and press OK:

3200 is the overclocked speed, 2666 is stock (I mean is what the RAM says on the sticker).

XMPS profiles give me only 2 options at 2666 (16,16,16).

Only work on overclocking one part at a time. I don't know for sure if your ram or your cpu is unstable. Set your ram back to stock, and we'll work on that later. After that, try small FFTs. If it is stable, try large just to double check. If it isn't stable, then increase the voltage.

This, yes.  Set the RAM back to XMP & stock voltage, don't overclock it at all, and test the CPU for stability.  Even if you have previously benchmarked the RAM settings stable, at a higher CPU clock & voltage, the memory controller may be under more stress & the RAM settings are causing the instability, or vice versa, the CPU not having enough memory controller voltage could cause the RAM to be unstable... it's all up in the air, which is why you should do one part at time.

 

I am not super familiar with the 10xxxK series' voltage ranges, but 1.32V sounds like it's decent for 5.1GHz, so I would test just that with the RAM on XMP with no OC & voltage set to what it says to set it to on the package/sticks (1.35V I would assume).

 

Also, 80C should not be causing a crash, so something else is causing it (pretty sure your thermal limit & mine are the same, which is about 100C on the cores).

 

How are your VRM temps with the sides of the case off, better or about the same?   Is it possible to put a fan blowing down on to the VRM area of the motherboard from the top?  I know it sounds sub-ideal to have a top fan as intake, but if the rear of your case is set to exhaust, it should work out just fine.  Any airflow directly over the VRM (be it pulling air off them or pushing are over them) is better than no direct airflow at all, and can make a HUGE difference in VRM/MOS temps.  That may be why you're crashing, your VRM may be overheating & instead of throttling, it's causing a crash first.

If VRMS are MOS on HWMonitor then the temps are great I think, below 80.

 

Currently at 5.1Ghz:

• CPU ratio: all core.
• CPU ratio: 51
• CPU ratio mode: Dynamic mode.
• Voltages override.
• Ring ratio 47.
• CPU core voltage: 1.32.
• CPU loadline calibration control: Mode 4

This works on Cinebench for multiple rounds, when doing a lot of rounds I get 90 C°, I think is stable with this settings BUT:

When playing PUBG it closes suddently almost every single match, windows is OK though, What could be the problem.

I'll try setting RAM to stock (only XMP) and try again.

O_O at "below 80" and "great" being in the same sentence. 

 

My MOS readout doesn't go that much above 40-45C under full load while OCed so to me those temps are high, though they are "within spec" since most MOSFETs/VRMs on boards can handle 100-110C before actually throttling/tripping OTP & shutting down, though it's entirely possible if you're going from 60 to 80C on the CPU within 2 minutes, that the MOS temp is going higher & maybe also spiking higher faster, thereby causing issues.  Just a possibility I thought I'd point out since some motherboards have very shoddy VRM/MOSFET cooling, especially when lacking airflow.

 

80 is better than the 98C you were showing previously though, that's a very good improvement.

 

Let us know how things go with the RAM set to just XMP/stock voltage.

Updates:

I ran 10 minutes of Prime 95 with this settings:

 

Currently at 5.0 Ghz with new fans agressive settings:

• CPU ratio: all core.
• CPU ratio: 50
• CPU ratio mode: Fixed mode.
• Voltages override.
• Ring ratio 47.
• CPU core voltage: 1.30.
• CPU loadline calibration control: Mode 3
• No RAM overclock whatsoever, NO XMP.

After 5 minutes of this:

 

I have got during those 5 minutes:

• 73C° on CPU (great!).
• 73 ON VRM (MOS on CHMonitor).

After 5 minutes:

• 83C° to less than 89C° on CPU.
• Less than 90C° ON VRM (MOS on CHMonitor).

Stable for the 10 minutes i ran it!

 

I'll try to:

• Put pull/push fans on my 240 rad (currently only have push fans).
• Change the top 120mm fan from exost to intake, in order to improve VRM temps, I feel this fan is doing nothing currently.

Even though is improving (on large FFTs test) when I test this (see image) I'm getting instant 100 C° on CPU, ¿Why? ¿Can I ignore this?

 

 

Thanks.

Download AIDA64 free edition & run just the CPU stress test (uncheck FPU, stressing CPU & FPU will make your temps go up a lot, so do that second) for at least an hour.  If it passes that, you can consider your CPU pretty stable, then if you are okay with your temps being toasty, run CPU FPU & Memory all at the same time, this will likely make the CPU thermally throttle with your temps, but it's still a good test to run.

 

If the CPU is hitting 100C but not crashing (and instead throttling like it should) then technically speaking that's fine.  I would definitely try Push/Pull as it can improve temperatures in a lot of instances, JayzTwoCents did a radiator fan configuration test that showed Pull actually performs better than Push sometimes, and Push/Pull universally improves temps by 2-7C, so it may actually make enough of a difference to stop the throttling you're experiencing at 100C.

I'll try that, I'll show the results this weekend, thanks.

 

I don´t undestand why is always stable for exactly 5 minutes (70° C on CPU and less than 70C° on VRM) but after that it goes up to 90C°.

It jumps from 125 W to 175, when hits 175 the temps go instantly up to around 90C°.

 

I tested it multiple times, and is always 5 minutes, after 5 minutes it goes from 125 W to 175W, when this happens temps go up.

Yeah, small FFTs is brutal. Here is what r/overclocking has to say:

Quote

How do I stress test my overclock on...

...modern CPUs? (AMD Ryzen, Intel Haswell and newer)

x264 Stress Test.

With Haswell, Intel introduced the design philosophy of having instructions - AVX2 - that get a lot of work done but produce an unsustainable amount of heat and draw an unsustainable amount of power on the assumption that they would only be used occasionally. Of course, some specific applications such as searching for mersenne primes with Prime95 absolutely hammer these instructions. Most use cases, however, are a fair bit lighter on them. x264 Stress Test uses a heavy real-world video encoding load that includes these AVX2 instructions, but doesn't hammer them the way prime95 does. While prime95 is not magically creating instability that doesn't exist, x264 can be fairly said to test stability for 99.9% of uses. If you want absolute 100% stability prime95 is still king, but needing this is very rare.

Some guides will tell you to use an older version of Prime95 because that's the "haswell compatible" version. This is a load of rubbish - in fact, the older versions referenced have not been updated for haswell and that's why they don't use the new instructions.

...older CPUs?

Prime95 small FFTs.

I'm not familiar with stressing the CPU with large FFTs. You should probably switch to x264 or AIDA as mentioned if you don't care about 100% stability.

 

If you do want modern prime95 small FFTs stable, you might want to use AVX offset. This will lower the multiplier by the amount you set when you run AVX workloads. So you might set 1 AVX offset with 50 multiplier to run modern p95 small at 4.9 Ghz and p95 26.6 at 5.

so, I'm stable at games and windows with:

 

5.0 Ghz with new fans agressive settings and pull/ push fans on rad:

• CPU ratio: all core.
• CPU ratio: 50
• CPU ratio mode: Fixed mode.
• Voltages override.
• Ring ratio 47.
• CPU core voltage: 1.28.
• CPU loadline calibration control: Mode 3

I only manage to overclock memory like this:

• NO XMP (it crashes if XMP on).
• 3200 (18/19/19/39) at 1.3 Volts from 2666 (16/16/16) at 1.2V.

Is it better to go 2666?

1.3v is good for ram. A lot of XMP settings are 1.35. I would use 3200. What did you use to stress test your memory?

Really only Prime 95:

 

And PUBG for hours.

I can´t lower the timings or go beyond 3200 because it won´t boot.

[keeeys]

Owned the 10700K and 240mm H100i XT, from what I see - Those temps are way too high and the voltage. I was able to reach 5.1 GHz in safe temperatures till I got to a 280mm one, but I'd do LLC4 and adaptive voltage, but fixed is okay with what you have as it's not that much of a difference. You can probably get to 3200MHz CL16 still - ram voltages are safe at 1.5v, for Hynix I'd do 1.45v maximum although there are different dies. Samsung B Die generalized is fine at 1.5v, Hynix dies in general can handle 1.45v, but I haven't tested 1.5v on Hynix yet.

 

Having said, it's good that the voltage is now 1.28v that I just saw - didn't see oops. I don't really like Prime95 since it doesn't provide a realistic real world test.

[EspinalAndres]

I went back to 2666.

3200 (18/19/19/39) gives me stuttering in PUBG and an old game (warrock, single core) that I play.

 

Strange but I can see it easily.

I think my RAM is Samsung B die (https://www.xpg.com/es/feature/552/).

So, is it ok to run the RAM at 1.45? I'm trying to lower the timings.

Whoops late reply lol. Yeah that's perfectly safe on B die. It's safe at 1.5V, but wouldn't go any further than that.
