Hi,

I have tried messing round with the settings of my pc after watching/reading countless tutorials. All I can achieve is a gaming pc that restarts all the time so put I everything back to stock.
After spending money on all these features I would really like to get the best out of my hardware so is there anyone on here who could hold my hand and go through a step by step process of overclocking/undervaulting to get the absolute best out of my setup? Pleeeeeewase :)

Z590 MSI gaming edge wifi
11700k
MSI 3080 Trio LHR
MSI MPG 360R
Lian-LI pc dynamic
32gb 3600 mhz corsair vengeance rgb. Can't seem to run them at more than 3200mhz.

Thanks in advance!
 
Thanks Darkhawk,

I will give the above a go.

I would like to get my ram to the rated speed, stable (3600mhz) - I'm currently using 3200 mhz through memory try it!

I would also like to overclock the CPU if it's worth it. When I'm gaming my CPU is showing 4600mhz. The only setting I have changed is Core Voltage Offset through XTU to -0.0110V. I also run ultimate performance power plan.

My GPU is overclocked through Afterburner and is currently using +86 on the core and 200mhz on the memory.

Was wondering how to fine tune the hardware for less power consumption and more performance. If that's even possible? If not, then just increase performance, efficiently.

Yes of course it's possible, but you are using the wrong methods. First off, High/Best/Ultimate Performance power plan are pure snake oil that will only cause unnecessary load, waste power and cause higher temperatures, see here. "Balanced" is the only way to go.

About the CPU, with the 11th gen i7/i9 CPUs, there is almost no OC headroom left, unless you're willing to accept a huge hit in efficiency for a measly performance increase. Due to the several different aggressive turbo modes of the high-end CPU models, those CPUs are driven to 99% of their capabilities once you remove the power limits and give the turbo modes free reign. For the last 1%, you will have to live with an exponential increase in power draw and heat production, which can quickly overwhelm some of the best CPU cooling available.

Intel went above the normal efficiency range of that silicon (which is mid-4 GHz), so it behaves - at stock, with power limits removed - like a substantially overclocked CPU would have behaved in the past. Meaning, the power draw is very high already, and the efficiency is quite low. If you still try to go above that with OC, you will see that the performance will hardly scale anymore, but the power draw and heat from the additional voltage required will rise very steeply. This is why, contrary to past CPU generations like the 8th gen, there is very little to gain by overclocking these new CPUs anymore (on the contrary, if you factor in the power consumption and thus calculation efficiency, which can suffer a lot).

Intel has pushed the higher-up CPU so models so much (a trend starting with 9th gen, but became really evident with 10th gen and newer), to the point where the 10850K, 11700K and 12700K are actually the better all-round CPUs, compared to 10900K, 11900K and 12900K. Sadly you cannot overclock your 11700K to perform like an 11900K. Intel heavily binned the silicon for the 11900K (pre-select for silicon quality). If your 11700K had the performance of an 11900K in it, without an exploding power consumption, rest assured that they would have sold it as an 11900K instead and made more profit. Because it is really difficult for silicon of that manufacturing process and CPU design to run with the kind of frequencies that the 11900K has.

What's more, overclocking can be deceiving if you only test the performance with certain benchmarks. It can make the results in selected benchmarks with full multicore load look a bit better, because people usually go for an all-core OC. But because it cancels out the intelligent power-saving mechanisms, it increases the core voltage which makes the CPU run hotter, so the CPU sometimes doesn't boost as high anymore in single-core or partial multicore load (which is much more common than full multicore load in daily use), compared to letting it boost normally. So you have nothing much gained other than in some theoretical benchmarks.


Much more important is to get your RAM run at DDR4-3600. Forget "Memory Try It!", that's just a last desperation attempt. First we have to get it going at XMP.
For that, update your BIOS to the latest version: https://www.msi.com/Motherboard/MPG-Z590-GAMING-EDGE-WIFI/support

1) Get the latest BIOS. It's the topmost one on the MSI support page for your board.
2) Extract the file and you will get a text file and the BIOS file. Put the BIOS file into the root folder of a USB stick/drive.
3) Enter the BIOS by pressing DEL during boot, go to "M-FLASH" in the BIOS.
4) Once M-Flash (the updater) is loaded, it will show a list of your drives. Select the USB stick and select the previously extracted BIOS file on there.
5) It will ask for confirmation and then update the BIOS. It's fully automatic from there, takes about two minutes.

Then try if it works at XMP, if not, we should be able to get it to work by changing some IMC-related voltages and maybe the DRAM voltage too.

Finally, about your GPU. Nowadays a straight overclock has gone out of fashion. Instead, undervolt it. This can lead to higher boost clocks as there is more thermal budget left. This is done in Afterburner with a custom voltage curve. Read here where i talked about it before. That method with the Curve Editor is the preferred one nowadays.
 
Wow, I really appreciate the quality of your response. Totally understand what you have explained.

So the only thing to change is;

Set power to balanced. I removed MSI centre a long time ago as I was getting the issues described in your link. Should I attempt to undervault CPU in balanced mode?

Undervault GPU

XMP memory to 3600mhz.

The XMP is what was causing me issues at 3600mhz. I have the latest BIOS.

I will have a go at what you have suggested and report back.

Thanks again.
 
Yes, if your main goal is a higher efficiency, you can also undervolt the CPU. I actually like to do this via the setting "CPU Lite Load" in the BIOS, it uses a lower frequency-vs.-voltage mapping for the CPU VCore (requires stability testing). It's similar to undervolting, but i like to look at it as an optimization to the quality of your specific individual CPU. Here you can find a post about that option.

If you have the latest BIOS and XMP is unwilling to work, can you do the following: Use just one of the 16 GB modules in slot A2, then enable XMP in the BIOS and press F10 to save and reboot, in all likelihood it should pass memory testing now (because it only runs as single-channel, halving the stress). Of course we don't want to run it like this, instead what i want to find out is, what voltages does the BIOS set once XMP is enabled and working. We might have to increase one or two of those voltages to make it work with both modules in dual-channel.

So then go to "OC" in the BIOS and make a screenshot of the voltages below Voltage Setting (press F12 in the BIOS to make a BMP screenshot to a FAT32 drive, then convert to PNG or JPG for size and upload here). Depending on what is set there, we'll see what we can do.
 
Hi again,

Took a 16gb module out and enabled XMP. I also enabled Intel C state a d C1E support.

I have set CPU LL to mode 2 so far, no issues?

I also UV the GPU using your link. Great results, dropped about 10 deg and 110w. Didn't notice a difference in FPS either. This is with one module in still. I'm using CP 2077 as a benchmark, ha.
 
I wouldn't do several things at once. So while we try to get XMP going for two modules, don't change CPU Lite Load at the same time.

Ok, the IMC-related (integrated memory controller) voltages SA/IO2 look more than sufficient for DDR4-3600, as usual MSI is generous there, so it's probably not the limitation.
Instead, set DRAM voltage manually to 1.4V and then try to add the second module in slot B2. If that doesn't do it, then it makes more sense trying to lower SA/IO2 a bit, by 0.05V or so. Because currently this is quite a high level already, more than necessary to make 3600 work. And sometimes the IMC is weird with the voltages.

Yeah, it's a good method with the curve editor, isn't it? Much better than the old overclocking approach.
 
So I changed to 1.4v on the DRAM and restarted and shut down. Then I out the 2nd module in where I'm the computers has resorted to crashing again.

Will now try the next step in lowering SA/IO2.

Just heading out at the min but will post back my results.

I appreciate, your time and knowledge on this.
 
No worries. The reason i said to test it seperately is, if you're lowering the CPU Lite Load mode, you want to test the stability with Linpack Xtreme, but when that test is too bottlenecked by the RAM performance (because you're in single-channel mode with one module), the results might not be very valid. So it's better to test for CPU stability when the RAM is running at full performance.
 
Hi,

Back again, I've been working away this week.

I went back to defaults (even started with a fresh install of windows) and all I have changed is - enable XMP and manually set to 1.4v.

The PC crashed as soon as I tried cyberpunk.

I went back into BIOS and I'm currently reducing SA IO2 by .005V.....
