The program crashes on start for me too. Tried the debug option and it shows an IndexOutOfRangeException. Not too sure how to get into the code where that is called though, I'm not really used to C#-related debugging (I'm more of a Java guy). Let me know in which ways I can provide more information and I'll look into it 🙂 Stack Trace:

Some data about my system maybe it helpls: Windows Version: 1909 (Build 18363.1082) CPU: AMD Ryzen 5 3600 Mainboard: Gigabyte B450 AORUS M Bios-Version: F50 - AMD AGESA Combo-AM4 1.0.0.4 Ryzen Master: 2.3.0.1591 SVM: Disabled There might also be some incompatibilities with my Windows 10 setup. I ripped out quite some privacy related stuff and enabled some security measurements not commonly enabled (although I tested with the security stuff reverted and got the same error) so maybe it has something to do with it. (Unfortunately I'm unable to test on a clean install right now) Would probably be helpful to know what exactly is throwing that exception so I can see if its anything related to those system modifications.

@zorandesign and "who" is going to "mature" the sw, if no one uses it? lol, beta doesnt equal having problems. best proof is R6 siege, which ran better while i played closed/open beta, than it does now after being out for 5y. completely ignoring the fact that no one forces you to use it. @Phoenix616 Tried the latest bios? use efiflash with /C flag

wierd if this tool is realy reducing single core perfomance what's the point of it

Not weird. Manual mode for Zen/Zen2 has always been like this, the tool is simply "lazy man's all-core overclocking + potentially undervolting", changing settings and trying them by itself (without manual operation) Everything that the tool does can be done manually as well (but as mentioned, manual mode cuts off the the single threaded boost) I guess those with threadrippers and such might benefit from it, as they bought their CPUs for running all-core workloads all day long, and they could be interested in finding the sweet spot. Those do not care about single thread performance.

Hey, hope I can get some help here. I have a Ryzen 9 3900x with an Asus TUF x570 board and when I run the program it just doesn't open. Anyone know what's up with it?

3600x. program starts but bluescreens my comp as soon as I try to do anything with it

Dont seem to do much other than set my 3600 to 4050 and only runs once Maybe because it says reference frequency: 6525MHz

This tool is fine if all you do is AVX workloads across all the cores but it really limits the cores overall perf with too small a delta between the worst ccx and the best. With everything loaded on my 3950x it went from 8890 to 9917 on my CB20 score after tweaking I actually went a bit further and upped the ref voltage to 1.250 giving me 4425 on CCD1 closed all the programs and did another run got 10221(edited) what im most impressed about is the thermals im now getting for having a fixed oc but im not overly comfortable with having a fixed oc on this regardless of thermals. So Im going to try pbo again with an offset voltage

@Phoenix616 Tried the latest bios? use efiflash with /C flag

Good catch. I recently updated it so I didn't expect there to be a new one. Unfortunately I couldn't get efiflash to work, it seems to complain about the system being 64-Bit? Updated it with the @Bios tool though (which doesn't have the /C / clear DMI option :S). After flashing it, it still didn't work so I assume the DMI clearing is the important part or its a different issue. Any way to clear that manually or get efiflash to work?

i have all the requirements and the program don't open

I have the same issue. In windows event viewer I'm getting this error:

@Phoenix616 use rufus to make a bootable usb (use freedos) and copy efiflash.exe and the bios. boot from stick to dos and try again. i renamed the bios file to x570.Fxx for mine. to make it easier and shorter to type in. make sure to load defaults after reboot, save and reboot again. i would run memtest v8.4 for full 4 cycles to make sure ram rans fine ( i needed to add 0.01v to make it "stable", vs V on previous bios).

On my system I have gone from benchmark of 3259 to 3703- 13.6% increase. Just using default settings for my Ryzen 3600

It just overclocked your system. Thst could be done in the bios.

Undying:

It just overclocked your system. Thst could be done in the bios.

Thanks for that. I'm happy to let the program do it for me

So what are your CB20 single thread scores compared to before?

So what are your CB20 single thread scores compared to before?

I was on a PBO 300 230 1 and my top clock was 4.775/750mhz on Core 1/2 before. on Core 3 and 4 and CCX 2 4.675. Now with the tool Im at 4425 on CCX1 and 2 and 4200 CCX3 and 4250 CCX4 (Despite CCX3 being higher quality apparently because I know Core 9 is the worst on my cpu) On CB15 I went from 215 to 206 so not a massive drop considering how much voltage drop I have and thermals CB15 multi I am 60 points shy at 4480 of my all time record where I was going after the best so my clocks were more than AVX limits. CB20 Single I am down to 510 so far from 537 but multi is a great boost going from 9917 to 10221.

Seems like the proggy needs work...;) My "silver sample" 3900X won't complete the C20 CPU bench because it stops rendering the stress test when the CPU hits 80.1C...;) Result = 0. Outside the program, the C20 test runs to completion no problems. The temp limit for the 3900X is 95C--program needs work. I don't *think* I'm looking at this the wrong way, but....

Did not see it listed in either article, is there a recommended power plan to be on with this, or will it override the power plan settings in windows so it does not matter?

You know you can increase the temp max and the power max? Ive pushed mine https://i.imgur.com/2TGPN6S.png

Don't take this the wrong way, but you should probably not be messing with this until you do some more reading.

Worked well on my Asus X570 TUF, r5 3600. I reset BIOS to default and set LLC to 3 and XMP per the guide. Cleared Sys Logs in Win10 to be safe. Downloaded CB20 and dropped it in the CB20 CTR folder Diagnostic showed silver sample, 4300Mhz 1275Mv with 4100Mhz 1175Mv undervolt. After running the OC I landed at 4250Mhz 1275mv. The hard part was realizing Dram Calc and CTR gains together. I had to leave all configs as is except for DDR voltage. Trying to modify power settings for LLC etc. Per Dram calc's suggested values was a performance hit. Some takeaways: - very sensitive to temperature thresholds which was supported in the guide with Gamers Nexus frequency to temp scaling graph. You'll want your pump at 100% and fans running at high RPM to see good gains from CTR, which was highlighted in the guide as well. 1usmis noted that AIOs and Open air do not perform as well for full stability OCs compared to custom water solutions.
