Hey, what's up guys? So after doing my under volting
and tuning video of the 14700K On my ASROCK Z790 PG
Sonic motherboard, I got some request asking to do a guide
that could be easy to follow for all users despite
having different motherboard brands. So the only way to go around
this is by using Intel XTU software, which is made by Intel themselves
and can run on Windows. In this way we can minimize
the need to do any change in BIOS So let's get started
by first installing XTU. You can find it easily
just by searching for Intel XTU and it should show up, when you first
launch it, You will be greeted with a simplified
dashboard showing you current metrics and some easy settings to change on the fly,
but we’ll just switch to the advanced view to get to all features
that XTU has to offer for us. So once we are in the advanced view,
my personal thing to do Would be changing the theme
to the dark one. Note that you need to restart
the application to apply Theme change. And now let's cover over the tabs
found on the left side The first one we have
is the system information. As the name suggests it,
just list your PC specifications The second one we have
is the speed optimizer. Basically, that's Intel one click feature
to overclock and optimize your CPU. But the issue is that it doesn't take
into account your cooling solution at all and not even do any under volting. All it does is raising your power limits. In my case, over 300 watt
and it also make use of thermal velocity boost while giving also small bump to the frequencies. But by just running cinebench 23,
temps will immediately raise to over 100 degrees and cause thermal throttling,
, as you can clearly see here. So I would absolutely recommend to avoid using Speed Optimizer
because it's only worsening the situation. The next tab we have is advanced
tuning one and here we will do
our manual tweaks and under volting. It’s the core feature of XTU
and we will get to it. In a bit after finishing exploring around, a cool feature
that I like is the stress test one. For example, I am doing an AVX2
stress test after doing my manual tuning, and I also wanted to show you
a very powerful feature that is the monitoring Hud here you can check
all metrics as you run benchmarks. And it's very customizable. For example,
you can change temperature from Celsius to Fahrenheit
and add more metrics as well. Additionally,
you can also customize the graph as well as logging data
and changing the pooling rate. If you prefer a quicker values update. So pretty versatile and useful. Now the next tab we have
is a benchmarking one, and here you can run a benchmark and compare
the score online was other users as well. Now naturally, the last thing you will want after doing
your changes is losing your settings. So on the profile tab you can export your profile,
which I'm about to do for my profile. And I’ll also include it
in the video description for anyone that would like to try it on. to See if it works out-of-the-box. Now finally, the last tab we have
is a profile pairing one. For example,
I assigned BIOS profile to Cyberpunk 2077, and that's absolutely
one of my favorite features because it makes it much easier
to have different profiles based on different scenarios. instead of manually doing the changes
every time. Another thing I wanted to show you,
if you go to the settings, here you can also check the option
restore tuning after reboot. This way, even when you shut down your PC
and whenever you start it again XTU would apply
your changes automatically. But of course,
if it noticed any instability, it wouldn't do it as a way
to avoid entering into rebooting loop. So with our tour finished, let's start
the real work in the advanced tuning. And here we are. At the first glance, it might really look crowded with many options
and feel overwhelming and complicated. But trust me, once you get the of it,
it will look much easier. Now, if you see the infamous yellow thunderbolt symbol, that means that
you can't do any under volting at all. You can only increase voltage
but not decrease it. here it says that under volt
protection is enabled and will prevent voltage
from being set below booting voltage. So the only way to fix
this is by going to bios. In my case, the changes that I need to do
are disabling under volt protection that is found in the CPU configuration
and also in the advanced section. I need to disable Intel
virtualization technology. And VT-D. If you are unable to find them on
your motherboard, bios feel free to ask me
in the comment section and I'll do my best
to help you out with that. But I want to know if your motherboard
chipset is neither Z690 or Z790 but B660 or B760. You would need to do an additional step
by changing the bios. Microcode. So I’ll link some articles.
I found that may help. But anyway, after those changes
the thunderbolt symbols will disappear for good. letting us freely under volt in XTU. Now the first change I'll do is reducing
the core voltage, offset to -165, which essentially use
an offset to reduce total voltage. The next one is changing
the AVX2 ratio to four, which means that the core ratio
will be less by four gigahertz as AVX workloads are hefty and letting them
have the same standard core ratio will cause so much overheating
and probable instability. Still, I'm not going to make any changes
in the AVX2 voltage guardband factor, so keep it at 1x. Next I'll do is changing turbo
boost power max to 250 watt. So I would suggest
you evaluate your cooling change. PL1 and PL2 accordingly based on that. For instance, I'm using a 240 millimeter
AIO cooler from EK. And I found it to be able
to sustain up to 250 watt. But of course my goal is to make sure
it doesn't reach that much of power consumption. But just making sure to not being limited
by power as a save measure. So I’ll set PL1 to 250 and PL2
to the 255. I’ll max out the turbo Boost power
time window from 56 seconds 128 seconds. Now let's tune the active core settings. If you go down a bit,
you should see a star next to two out of the eight p-cores
this means that those two cores are the fastest ones. And if you look here out of the box,
they are fused at 56 ratio instead of 55 as the rest of the p-cores. So I'm going to do the following to max those two cores,
to 58 while keeping the rest as 55. And as I do that you see above,
when one core is active, it's now changed automatically to 58. so that means
when one of those two cores is active, it will push itself
harder to 5.8 gigahertz. In this way, we push the single core
performance as much as possible. While under volting. I’ll also set when two cores are active,
the ratio should be 58 as well. So in this way we are taking full advantage of this
too fast cores as much as possible. But note that when you change that,
it automatically change all cores to 58. So make sure that you dial
the rest of the cores to 55 while only keep the two first cores
as 58. A faster way will be by shift-click
to select more than one core at a time now i’ll keep from three active cores and on the ratio will be 55,
which is the default. Now let's tune the thermal velocity boost. All you have to do
is enabling it and set following. When temp is 90 degrees,
we reduce the ratio by one, while when temp is 95 degrees, we reduce
it further by two ratio. In this way we maximize performance
while helping the CPU to not overheat so the point of thermal velocity boost
that the CPU will boost as long as it reaches those temps to maximize performance
while having better control of thermals. You can also enable
thermal velocity boost per core So I'll do the same here as well. And here you can also shift
click to modify them all at once. Now, after finishing with the p-core tuning,
let's head over to the e-core This time I'll set when 1 to 11
c-cores are active. ratio should be 44. But when 12 efficient cores are active,
the ratio will be 43. That's because I found some stress tests
like OCCT that’s It's unstable with efficient cores
being above the default 43 ratio. So I’ll just do this trick that
as soon as all e-cores are active to have normal ratio, just a smaller ratio boost
when 11 out of 12 e-cores are active. Some things to note here that I didn't change the reference
or bus clock at all from 100mhz and I do not recommend you do
so as it's going to push all cores, cache and even RAM clock and the possibility
of instability is likely 100% so that's why I don't recommend that. Also, I didn't change the processor core
ICC Max, which is unlimited by default. here I want to clarify that
for the rest of settings like for cache. I kept all as default that
because each motherboard might have a different kind of way
to tune cache ratio. For example, mine keeps it 3 ratio less than
core to be stable, so that might vary
depending on your bios, features, etc. I just wanted to make sure
that those changes could potentially be stable
for as many users as possible. So with all done. We can now hit apply button
and thankfully we got no bad signs so far. Now here I want to show
if I unhide the right panel, You can see the settings set at boot versus
The ones we just proposed in XTU. So in that way, you can compare
the difference between the boot and the ones we just set so in order to save your
profile, you can do so by clicking here. Also here, I want to show you
some important points to look for in bios in the voltage configuration. I've set so load line calculation
to level three, in ASROCK motherboards lowest voltage drop is level one
and the highest VDROP is level five. So level three is the best balance between stability
and not having high thermals over time. For example, if I set it to level four,
it's going to be unstable. That's because voltage drop
will be more prominent instead if i set it level two,
it will have less voltage drop and also going to be more stable,
but gets much hotter over time. So in my case, level
three is a sweet spot and also load line calibration level settings
may vary between brand to another, but as a general rule,
always choose the middle one If you have trouble deciding
which one to set on your board, please let me know in the comments
so we can see that together. I also want to note that those tuned settings
work fine with XMP profile so you can enable it in bios as well
without an issue. Now, in order to make sure our tuning
is fully stable and working, it's highly recommended
that you run a different set of stress tests and benchmarks to ensure
we are not compromising stability here. Also it’s recommended to try more than one. That's because, for example,
if it was a stable in Cinebench R23, it may not be the case in OCCT
or in Ycruncher, so things could greatly vary
between workloads. That's
why it's always better to do all of them and then call it a successful CPU
tweaking. So I'll get started by doing both single
and multi-core in Cinebench R23. And here is the result before and after. For multi-core, we got 35878 and for single core we got 2216. I would say it's a good uplift that because
we are running at the lower voltage. Let's now head over to AIDA64
and do a stress test For one hour and also in AIDA64. It was all clear. So let's switch gears to OCCT And in here I'll do a stress test
in both SSE and AVX2 workloads and to make sure it's
as challenging as possible. I'll be choosing a small data set that draws the most power and provides
the highest stressing scenario possible. And also for the mode,
I'll be choosing the extreme one to make sure it's more demanding. So I'm going to run each one for an hour
to make sure it's all working. Let's go also in here it passed without any issue. And that's quite reassuring. But it's never perfect
without Ycruncher as well. So let's give it a spin
and see how it goes. Also in
Ycruncher it finished the test without any error. So I will say we actually managed to get
a stable system POST tweaking as well now after doing all those tests, let’s check now
the gathered data in HWINFO. So the max p-core we got is
5.8 gigahertz for our fastest cores and for the rest 5.5 gigahertz as in before fast cores got to 5.6. And the rest of cores
5.5 gigahertz as well. Now we get to the E-cores and in here, post
tweaking, all of them managed to hit 4.4 gigahertz at some point while before Max was 4.3 across all of them. Now we get to temperature
and in here post tweaking. The maximum recorded temp is 80
degrees, with no thermal throttling and that was gathered
throughout all those tests. We have done, while before, with just cinebench
It reached 99 degrees and even caused a thermal throttling
as it's shown here. And finally, for power draw post tweaking The maximum is 241w while before the maximum is 253w So I would say the outcome is very good
and we truly have reduced temps by quite a lot. Now here I want to show you something by default, sometimes in HWINFO
values are rounded So even though we have 5.5
gigahertz or 5.8, they are showing a little less in HWINFO Also BUS clock is
100 megahertz, but here is showing 99.8 So sometimes HWINFO
gives round values and that cause some difference
in the shown value. So if you want to fix this issue,
go to settings and then go to the customize tab, search
for the ones you want to adjust Shift-click. And here you can add more values
until they get to the actual values we have. And same goes for the E core As for BUS clock, just select the decimal
digit as zero and it should fix it. And optionally
you can also change the color. So just wanted to show you about this possible fix for HWINFO
reporting wrong values. That's only a fix in case you are like me that prefer to see
whole clock number instead. Now, finally, I have prepared
three games benchmarks to see how do difference translate in gaming. So overall, even in gaming
we managed to reduce thermals and power draw greatly
thanks to doing those tweaks in XTU we managed to check all three boxes
for our 14700K less voltage, less power draw
while still having a good performance. Now here I want to show you
in my ASROCK motherboard There is a new feature
called CPU Indicator and here it shows you
the silicon quality of your CPU For example, mine for p-core it's
75 while for e-core, it's 69. The overall CPU quality score is 73. Now the reason I'm showing you
this is because if my CPU quality, which is below the average, is able to get
this kind of tweaking results I'm positive if yours
has higher rates. It can even get a better outcome. And also in this guide,
I wanted to show you the method that I would do in XTU But you may choose a different approach
and could even lower P and E ratio to under volt it further. if you've got any question or issue, please feel free to reach out to me
on the comments section. Or over at TECHOSAUR Discord server. I'd be so happy
to help as much as possible. Also, if you like this video,
please give it a thumbs up and subscribe to be up to date with all my latest guides
in tweaks and updates. As always, thanks for watching
and see you in the next one.
