Did I miss a Zen 4 OC and result thread?
Zen 4 memory arrived

It's for Vcore, newguy1 asked about VSOCDer8auer has a video on 3 x Zen3 cpus he ran for 4000+ hours at 1.4V,with little to no detrimental effects. Not Zen4, but the only "study" I know of.
Since Zen 5 is designed to operate at over 90C, the only thing you are telling me is that your chip isn't running at optimal speeds.Anyone else had a recent bios update that has like notes like below?
TUF GAMING X670E-PLUS WIFI BIOS 0821
"1. Update AGESA version to ComboAM5PI 1.0.0.3 patch A + D
2. Improve DRAM compatibility
3. Improve system performance
Normally see the temp fly to the moon to 80c+ even in cinebench but after I updated the bios, I only just noticed how much better the temps are?

Great, now test it in 7zip, Blender, Handbrake, Rapydmark, etc. Then get back to us about how much 'faster' your CPU is.Found a neat trick not sure if it was used in previous gen Zen CPU, but it will improve multi-score pretty good if you use PBO.
Originally limited my temp to 85c in the bios and did the PBO's setting from Optimum Tech video "Fixing Ryzen 7000 - PBO2 Tune (insanity)"
I was testing my CPU to optimise the PBO setting and realised setting the temp to '75c' in bios actually improved overall multi score.
If you think about it, once the CDD1 hits 75c, there is more power available then which is allocated to CDD2 which will make it clock higher, which would bring the overall average of your multiscore higher while having better temp as well. Obviously CDD1 clocks will be lower (not by much), but we're looking to achieve better multi-score overall.
Hope more people can test as my sample is really low and I only used Timespy CPU test to try it

A special note here. Zen 4 is on a different process, so what applies to Zen 3 most certainly does NOT apply to Zen 4. Don't read anything you see in forums or other social media and take it for granted, unless you have money to spare on a new CPU. I personally would not be comfortable running Zen 4 at anything over 1.25V with a static overclock, and a 7950X costs slightly less than an hour of my current pay.It's for Vcore, newguy1 asked about VSOC
Fortunately we still have ESU, the Power Unit in Joules; that's why CoreFreq managed to read, per Core, the consumed energy.I'm on latest bios, awating for a newer one with tREFI option for fine tuning RAM, already contacted MSI support asking for it.
Its a few seconds faster on handbrake, not tried it on blender or the others you mentioned.Great, now test it in 7zip, Blender, Handbrake, Rapydmark, etc. Then get back to us about how much 'faster' your CPU is.
Not sure but it is still doing better than majority of 7900x CPU with 3080ti using Timespy which works for me, no crashes or anything so ya know.Since Zen 5 is designed to operate at over 90C, the only thing you are telling me is that your chip isn't running at optimal speeds.
That's interesting, i will have to try that out, I can't get it to boost there. Is C state and boostit different things? Did your temps increase much?It won't boost over 5.5 no matter what load and temperatures ? I could be wrong but i think i heard somewhere something about C-State needs to be either on or off with latest AGESA ? On my Asus board theres an option called Medium Load Boostit that removes that 5.5 limit "bug" or "feature" not sure how to call it
After enabling it and +200 offset in PBO, 5.7-5.75 works in games without problems, even in games capable of using multithreading and drawing lots of wattage like Hitman 3.
Guys, I've been testing my system in Aida64 and prime95 stability tests for a few hours each, and so far, no crashes when RZQ/5 is set to all DRAM impedance options.I'm starting to wonder if my DRAM stability problems might be related to DRAM impedance (which isn't something I've ever tested before).
I tested RZQ (240Ω) for all DRAM ODT settings and my system wouldn't boot.
RZQ/2 - Boots, but failed stability test very quick.
RZQ/3 - failed stability test in a few minutes
RZQ/4 - took a bit longer to fail
RZQ/5 - Seems to be stable. Will see.
Presumably, RZQ/7 should work fine also.
Memory is what can get you best improvement these days since there is so little cpu OC headroom and xmp mostly sucks. ( not everything responds to memory though)So out of curiousity since everyone seems to be getting good results with memory OCing, I'm guessing it gives a decent boost? My experience with Memory OCing was it was usually a pain in the you know what
7950 gets here tomorrow, wasnt planning to mess with Memory OC but if everyone else is having good luck maybe ill take a crack at it
Is there a good master thread or guide to go with so i have a starting point? Havnt built with DDR5 yetMemory is what can get you best improvement these days since there is so little cpu OC headroom and xmp mostly sucks. ( not everything responds to memory though)
I'm providing a change for Vcore and probably Thermal readings; can you please pull and try latest develop branch of CoreFreq ?I'm on latest bios, awating for a newer one with tREFI option for fine tuning RAM, already contacted MSI support asking for it.
It shows voltage now although it's fixed at 1.55V, no temp reading yet.I'm providing a change for Vcore and probably Thermal readings; can you please pull and try latest develop branch of CoreFreq ?
1.55V is unfortunately not a good reading, can you show the Voltage or Sensor view ?It shows voltage now although it's fixed at 1.55V, no temp reading yet.
