    Posted: February-22-2021 at 7:46am
For the last several hours I'm making through the NickNs Overclocking Z490 10 Series guide. I set everything exactly as per the guide, I read every word in it. Now I started with the first OCCT:Lin test and stumbled upon a big discrepancy and I'd like to clear it up before continuing with anything. In the guide there's a line: "Real Time Vcore OCCT:LIN 1.190v - 1.195v could be slightly higher or lower". My real time Vcore is mostly at 1.279 and max is 1.288 (when I took a picture I'm attaching it was by chance at 1.288). That's almost 0.1 above what it should be. That probably doesn't fall into "slightly" category, or does it? Also, my temperatures are around 80°C so I guess I lost the lottery big time. Again, this is the absolute first test in the guide for 5GHz no HT. I ran it for 20 minutes without errors but then decided to stop because of this high Vcore number. My question would be what does this mean, is it bad or can I do something about it?

My computer specs:
Motherboard: ASUS ROG STRIX Z490-G GAMING (WI-FI)
CPU: Intel Core i9-10900K
Cooler: SILVERSTONE Permafrost 240mm ARGB AIO WHITE water cooling (SST-PF240W-ARGB)
RAM: ADATA XPG SPECTRIX D50 RGB 32GB DDR4-3600 CL18 (AX4U3600716G18A-DT50)
PSU: SilverStone 850W 80+Gold Full Modular (SST-ST85F-GS v 2.0)
Case: Fractal Design Define 7 - Black Solid (FD-C-DEF7A-01)

Now my expectations dropped and I just hope that I can achieve 5.0Ghz with HT on. I was saving for this computer for years and now this.

I can of course provide any additional information needed. I'm refraining from any further tests before this is cleared up.

I have not gotten to where you are at yet....so I cant help much.

But I think the guys that can help you are going to need a picture of the voltages you have set and the test you are running.

Are you sure you are running the Linpack test....the seconds test test, the Large Data test, seems to require higher voltages....so if you are running that test....

Yes, I'm sure, it's the Linpack test.
Here it the picture from the BIOS how I set Offset voltage (I got exactly 1.315 in HW as per instructions):

The correct OCCT version is also important....not the latest...but the correct version!

wich version are you using?

Ah....I see now you are using a different MB than the outline was tailored for.

That could be the reason too.

Surely others will offer better advice (based on actually having done it)....but I dont know...maybe it makes sense to load a Bios from around the same time as BIOS 607 for the Maximimus XII Hero (wifi) came out?

Well, the guide says it's for the Z490 and I do have Z490. It could be the reason it's not the exact model, I don't know, that's why I'm asking.

quotes from the quide:

„I have outlined this with a specific motherboard, processor, memory product and cooling solution for duplicated success and engineering reasons.“

„IN THE EVENT a different model motherboard may be used for this, make sure it is a z490 Asus product with the 10900K processor as every manufacture has their own way of designing boards and BIOS systems. I can not say this outline will work exactly the same with different Asus motherboards. Most likely it will not work with a different manufacture motherboard. You will need to extrapolate and work it out yourself using the information here with a different board.“

It would be great of someone here has the same MB as you.

Then you could compare results and see if this is normal for your board.

Yes I know....do I sound like I am blaming you?

Just trying to give you ideas as I am reading through page 26 of a guide I read for the first time.

I can stop if you want to...just say so.

 HT off?

I already read through the whole guide 2 times. As I said a couple of times I did exactly what the guide says and I'm on the first test (OCCT: Lin). There is no HT test before that so yes, HT off. I don't want to be disrespectful, I appreciate any help but this thread is getting quite long and not progressing at all. I'd like to hear from somebody who knows why real time Vcore can be so high on the first test and is it ok, can I proceed with the guide or can I do something to lower this number.

0Artur0 -- The 1.288 Max VCore is not a problem at this point.  It is well below the 1.48v hard ceiling.  Your Max CPU temps stayed under 80C (79 Max).   At no time should real time Vcore spend anything but a transient second get above 1.40v.  

Question: where does your Real Time Vcore reading "hover" or spend most of the time?   

Right now its safe to continue.  Your initial readouts are in line with what I experienced with OCCT:LIN at 5.0. on the Maximus XII board.  I wouldn't be surprised down the line that there will be differences between the our two boards in their responses on this tuning guide because there are hard differences between the two boards in the VRMs and the BIOS code.

Its good that you are being cautious and keeping your eye on things.  This definitely won't be a "slam it and forget it" proposition! Wink

That's the thing. It's around 1.279 pretty much all the time. What scared me is the fact the guide states it should be around 1.190-1.195 which is significantly lower.

Understood!

  Your (-) Offset voltage will likely be adjusted significantly as we move up to 5.1, 5.2.  Like I said in the above [now edited] response, the BIOS and VRM systems are hard coded differently between the Stryx and Maximus boards.  That doesn't mean you cannot attain your goals (only the real-time trials will tell) but it means that we are dealing with a slightly different breed of cat here -- even though they are both ASUS cats...

You will need to apply the underlying idea behind the approach, as the exact responses almost assuredly will be different between the two, so just expect that from the outset.

Thank you!
I just wanted to be sure this discrepancy isn't something catastrophic because there's quite a difference.
I doubt I will be able to go much higher, those temps are with HT off, I'm yet to test it with HT on. After running OCCT Linpack for an hour the Max Package temp went to 87°C but it was stable. I just finished OCCT Large data set test and it also passed with Vcore real time temps around 1.288 and Max being 1.305 which is also way above what the guide says.

Max voltages don't look too bad...a little high maybe. But there should be moments in LIN where the Vcore drops to 1.2V or so. Might need to check the Load Line Calibration setting? I have no idea if the same one should be used for the STRIX.

I experienced OCCT CPU to be easier to get a load reading from, not talking about the MAX reading here. And you say you are at 1.288 most of the time?

You could start experimenting with lowering the offset voltage until Vcore drops a bit because it seems there is a margin already. In that case, you'll have to forgo the stated VID of 1.315 since it will drop with the offset, and just focus on Vcore.

Real Time Vcore OCCT:LIN 1.190v - 1.195v could be slightly higher or lower. 
MAX Vcore column 1.255v - 1.289v could be slightly higher or lower.

Real Time Vcore OCCT:CPU: 1.230v - 1.238v could be slightly higher or lower. 
MAX Vcore Column: 1.255v - 1.289v could be slightly higher or lower.

Now I'm torn... I started testing 5.0GHz with HT on and after about 45 minutes on OCCT:Linpack I got BSOD. Previous tests with HT off didn't require any VID, VCCSA or VCCIO changes. Since it was BSOD, which would probably indicate that the voltages are too low, I was thinking of raising VID, not lowering it 🤔

You weren't testing with HT back then LOL

I would still go back to HT OFF to get some kind of understanding why your load Vcore appears so high, before even starting with HT.

What is your load Vcore with OCCT CPU?

It was real time 1.288 most of the time and 1.296 max.

I already went ahead with HT on testing. I guess I don't understand this approach because I expected at least 10°C higher temps with HT on but that was not the case. The temps were pretty much the same as with HT off. What's happening here? The only thing I changed in the BIOS was HT from off to on. That's it. After I raised VID for 0.005 the OCCT Linpack test ran for an hour and no crashes this time. Here are the screenshots and a photo that shows that HT is in fact on. Also, since I raised VID for 0.005 the Vcore also raised to real time 1.296 and max 1.305. Most of the time the temps were in the mid 60s and occasionally raised to 80s. I thought there was some downclocking going on but the speeds were at 5000 MHz all the time. Can somebody explain what's happening?

The OCCT Linpack test wasn't designed to stress test CPU HT capabilities.  The actual threads are running spread across the logical cores of 20 vs 10.  This is strictly a stability test with the AVX-1 instruction set for CPU heat and with the memory in play.  I saw the same relative temperature changes on my system i.e. cooler on the AVX w/ HT than AVX w/o HT.   That does not mean that when running "real life" applications or a simulator that is coded to take full advantage of HT, that you won't see the higher temps. OCCT CPU is about overall CPU stability alone.

Another thing you need to keep in mind -- on the power/temps you are in the safe range now, but already getting up into the high 80's:  The guidelines were established amongst 10 plus systems all with 360mm radiators on the cooling system and you are working with a 240mm radiator, your "ceiling" and thermal limits will not be the same, just as the voltages/VID will not be the same for running a different class of MB than the outline was painstakingly worked out with.  With the caveat that the max voltages and temperatures I would fully consider hard limits as given in the guide.

To a degree we are not comparing apples to apples here.  If you were on the exact same system as the outline was derived from or even a Asus Maximus class motherboard with the same cooler, then I would expect you would be very much in-line with the ranges and temps we found consistently across the original Maximus XII boards.  The more differences in your system set-up compared to those used to make guide, the more deviation from the given expected ranges.  It is what it is.

With cooling limitations as another difference in yours vs the guideline systems, you may or you may not make it much higher in clock speed.  On the plus side, I think you've reached your goal of 5.0 HT safely.   You may make it stably to 5.1, but we are comparing an orange to apples, if you know what I mean.  Also, remember that you must also run HCI Design Memtest through at least 8 full passes (800% or higher which is far better) before you can call the clock stable.  You may still have some minor tweaking to do.  I just want to make your expectations realistic for the hardware you purchased.

Best of luck!  If you do find your temps get up to 93C, then MAKE SURE you set up the Maximum Watt and CPU Temp Limit Safety Net as outlined before going further, with Long Duration Package Power Limit, Package Power Time Window, and Short Duration Package Power Limits.  This should ensure you can protect your investment that you saved up over time to put together.

I wish I'd knew more about liquid coolers before I put together this computer. The price difference between 240mm and 360mm is minimal. I'l make a research how better the 360mm cooler is and if it would make a temperature difference needed. If it will make a difference, I'll eventually switch.
In general, I'm well aware there are differences in hardware between the guide and mine. I do not expect the same results but when my expectations differ so much from the actual results (Vcore, HT on temps) I have to ask.
I did an over night HCI Design Memtest and it didn't produce any errors. I guess I'm stable at 5.0GHz but since the temperatures are getting pretty high (one core even hit 90 on the OCCT Linpack stress test) I'm doubtful I can go to 5.1GHz... maybe with a better cooler since I didn't full on hit the wall but I very well touched it. 
One more question regarding setting the Watts. Do I look at package temperature ar a single core temperature? Following the guide, if I look at package then I should add 10 to the max watt measurement (which was 235.44) but If I look at single core, since one raised to 90°C then I should only add 4. Also, should I round this number down to 235?

I'd have to agree with you here.  But 5.0 on all cores with Hyperthreading enabled is nothing to sneeze at!  That will be a solid performer for whichever sim you plan to use.

Package Temperature.   Round the 235.44 to 235. 

You may still be able to tweak the memory and you still need to verify PCIe video adapter 3D load stability. (Step 9 in the Guide). If you want to go further you will need to address your cooling solution.

Yeah, I'm actually pretty happy with 5.0GHz with HT on, major improvement from my old 4790K. I did successfully complete 3DMark tests also so it appears the OC is completely stable. 
There is no way I can go to 1.370V, required to even start testing 5.1GHz, the temperatures would be too high. I repeated 1:30h OCCT Linpack test today and the temps on CPU package went to 87°C with 2 of the cores hitting 90°C. Raising volts from 1.320 to 1.370 would push at least those two way too high. It would be nice to have 5.1GHz but as I said, I don't have any regrets. Maybe I'll buy a better cooler one day and I'll be able to push it to 5.1. Thanks for all the help!

Thanks to NickN and the gang for this guide! It was very helpful.

If sometime in the future somebody with the same motherboard reads this and did attempt an OC following this guide, I'd like to know what your Vcore temps are. Even though everything works and it's stable, this remains a mystery. Maybe it's the Strix motherboard thing, maybe it's something else.
Also, if somebody has any idea, based on the posted temps, is there a point in my case to buy better cooler (360mm) and attempt 5.1GHz? I did a research and didn't get a clear answer. Some say it actually won't cool much better, it's just going to be quieter. Maybe for a few °C but that's not enough in my case. I would need like 10°C headroom.

I'm not sure what you are asking, here, 0Artur0.  The ranges between Vcore and Temps are listed in the Guide.  To be honest with you there is a limit on what can be done to assist you when we don't have our physical hands and eyes on your system, only you do.

In all fairness, you came to dinner late, after you purchased your build parts.  There are differences in the class of board and its power phase, components and utilization of the multicore enhancement implementation between the Strix class of boards and the Maximus.  Some of these things are technically beyond what can ethically and safely be advised in a Flight Simulator Forum, particularly with due regard to maintaining longevity and safety to your equipment investment.

You can research for yourself the relationships between VCore, VID, and LLC (Load Line Calibration) and power phase control of various lines and brands of motherboards. 

Here the goal is to help sim enthusiasts safely and sanely get the most from their experience.  This is not an Overclocker Forum as such.  

I pointed out the cooling solution, but there may well be more to the story.  I cannot tell if your cooler pump is making proper contact with the heat spreader or that your choice or manufacture's choice of thermal paste is good -- if there is a large bubble between the two preventing good conduction of heat away from the CPU, if your CPU cap is true or dented. This is not suggesting you did anything incorrectly, I'm just pointing out you are now asking for advice I cannot honestly give.  You've reached the end of what I can do in a forum and in good conscience.  Sorry.

There is no way put a scope on your board and see the response curves, and those things that can only be done by a very knowledgeable technician with overclocking experience or an electronics engineer who knows what he is doing.

Quite honestly you received the best and most insightful end-result of literally hundreds of trials at all different standby voltages, offset voltages, et al, cache frequencies, VCCIO, VCCSA, almost ad infinitum.  This product was arrived at by careful analysis and deep understanding of very advanced computer engineering concepts with this expertise provided to the community by Nick.  The guide you now have is the product.  It was not the means to developing the product -- that was lot's and lots of trials and data all put into Nick's hands and orchestrated to this end.

The guide is what it is.  You have a safe clock.  You understandably want a higher clock (although the actual visible performance difference in the simulator between 5.0 and 5.1 is not likely to be as big as you might think.)  

If it is just "bragging rights" to have a higher clock than the next guy, I can dig that too.  But that is not OUR purpose in publishing the guide to fellow flight sim pilots.

I do wish you best of luck in your endeavors, your flights, and your landings.

All I meant was that if somebody with Strix motherboard attempts the OC following this guide to report their Vcore temps, so I can see if those discrepancies were due to different motherboards or something else. That's all.
