EXPO kits cap at 6000mhz the sweetspot AMD stated and most don't tune their ram there was no reason to ship any bios over 1.2v vsoc

The best way of solving this for me was to get a 13700K and Z-690 A pro. AM Dip is gone, and DDR4 OC is moderately painless all of the sudden. :D

@@handofhuang5250 Well I wouldn't say outright better. But Going from Zen to intel, i found the whole PC experience better. I was on Zen for an eternity for all versions. Less idle spikes, and emulation is better. I still think X3D is great for normal people, just not me.

[@denvera1g1]

Before i bought the 7950x for my server i found that 1.2 is apparnetly the max set by TSMC, so i set it to 1.1, what does it matter to me though, all core i needed to stay under 90w, and preferably under 75 so the fans on this small server weren't screaming. Still wish Intel would come out with an all E core Xeon that i can thrown into LGA1700, say 48E cores with a socket power of 120w, but better multi-core performance of say that 280w 32 core thread ripper As it stands i have to hack in hardware acceleration for the Ryzen iGPU, Intel's iGPU just works but they dont make a CPU with good enough performance per-watt for my needs.

[@RainOnWarpaint]

What do you think about the new Asus x670e bios update? It's seems not only it didn't fixed the issue with the SOC voltage, they also voided consumers warranty.

[@troyxhoward]

What was the rated speed on this ram?

[@MadPeteST]

What you'll probably find based on my extensive testing is that it seems to be stable at lower SOC voltage but isn't (it'll pass OCCT, Aida, Prime 95 for hours fine), but then it'll ransomly crash out during gaming etc. My chip needs 1.33v to do 6400 stable (and I think I have a very good one), it's taken me two weeks to find this out and LOTS of testing. I might drop it down to 6200 and lower timings if it's happy at 1.3v or lower now.

[@ryanstewart68]

I'm running at 6200, I needed almost 1.4v to hit 6400. 6200 seems to be MUCH easier on the IMC and I don't like fire...

[@Heisenberg355]

I have 6000MHz Ram and im really unsure whether I'm stable. Currently, I'm on 1,15V vSoC and everything seems stable (y-cruncher, OCCT, prime95, Linpack, aida64 and playing LoL) However, according to what I see here, I'm probably not stable... How did you notice instability exactly?

[@ReaperHackz]

Glad i got to make this stream but yeah weird that it took so much more volts as you said deff not worth all that extra volts for not even barley a difference.

[@Robert_Paulson1360]

Increasing SOC above 1.20v causes nothing but problems on my B650M Aorus Elite/7700x. I leave it at 1.20v but there is a process for getting a stable 6200mhz. I have to boot into windows w/stock bios settings, then shutdown and boot with EXPO enabled, then shutdown and boot again with 2033/6200. If I try to do all bios tweaks at once it will NOT boot into windows at EXPO 2033/6200. Once I follow this procedure though I'm good to go until bios update. I can get it faster with lots more tweaks and voltage but it makes zero difference in gaming far as I can tell.

[@fatalradius]

Hey dude, love your content. By any chance, do you have a video on under volting a 13900k? I know you focus on overclocking and getting those gains, but just wondering how you would run a 13900k so it won't run too hot if you have limited cooling options.

[@cjceeez9897]

When i had the 670 extreme and 7950x i had to enable memory context restore and pwer down mode to get any kind of stability. This 3d update looks like a wash when you have to finalize implementation and scheduling yourself. At this rate, the amd chips should be 300 dollars off in its current state

Think it's going to vary a lot depending on your CPU/MB/MEM set up. Probably a large percentage will be able to hit that 6200 at a low SOC voltage. They'll probably be a large varying with anything higher. My 7900X/B650E Taichi/Corsair 6600 64GB kit we'll hit 6400 with 1.235v

SOC voltage seems to depend on which gpu you have. put a 4090 in and see if it works at 1.2v. My 7900x needs 1.27v in windows, 1.32v in mbo for it to work properly. It will boot at lower voltages but the gpu defaults to gen 3 and only works in a slow safe mode. Please check your gpu is working correctly at 1.2v.

[@BaBaNaNaBa]

the way people on hwbot get ddr5 6400 and 2200 fclk. is by using a chiller, not your normal water loop or AIO

[@Hoofie]

No, it just comes down to the lottery. Some chips are just better than others when it comes to that. Many people out there running 6400 2200fclk with normal cooling. Hell, even 6600 2200 if you're lucky.

[@Malklaw]

@@Hoofie i guess thats true mine runs 2200 but with 6200 cl 28 1.46V air no problems but 6400 even 6300 needs probably tons of voltage one way or another

I can boot 6600 2200Fclk at 1.3vsoc, but its not stable. Would probably need more voltage to get it going, but would have to revert back to an older bios for that to be a thing. But yeah, some chips have no issues, while others stuggle hard with 6400.

​​​​​​@Hoofiew whats your vdd vddq and vddio/Mc voltages at 6400 ? Mine is booting with cl30 6400 flck2200 at even 1.2 soc but ITS unstable i think becouse vddio voltage vdd vddq or to tight timmings or even maybe gdm off or to high flck... But IT seems to be possible i guess in my case stock timmings and gdm ON is the couse but im curious about your voltages that would be helpfull for me ...

[@Hoofie]

@@Malklaw At 6400c28 2167Fclk I'm running VDD at 1.52v, VDDQ at 1.42v, VDDIO at 1.25v, SOC at 1.25v. VDD voltage depends on sticks, and mine arent the best. 6400c30 might require a bit more than 1.4v, so something like 1.43v "should" be ok for 6400c30. Again, depends on your sticks. Generally speaking, a-die requires around +/- 1.4v for CL30, 1.5v for CL28, 1.6v+ for CL26, and like 2.1v+ for CL24 at 6400. Anything above 1.5v usually requires cooling, so probably not recommended for daily. But yeah, every CPU is different. It could just be that yours isnt able to run 6400 stable. Plenty of CPUs out there that can boot 6400 2200, but cant run stable no matter how much voltage you push into it.

[@radugrigoras]

Voltage is beyond the point, the point is that the CPU can short itself and not shut down on thermal…I can go into my BIOS right now and set the voltage to 1.5 on my Intel and it won’t burn up, it will just power off..This chip is flawed from a design point, as it ages that limit of 1.3 will start to creep down, 3 years from now 1.2 might cook it..AMD is like taking a stock 2L Honda engine and strapping on a 64mm turbo off of a cumins diesel, sure she will go like a bat out of hell for half of a dyno pull, but she’ll explode, not a matter of if, but a matter of when. Stick with what works boys and girls, stop chasing saving a couple bucks and getting an extra 2%. All the stock holders are FAFOing around too, nobody in the server space is loyal, if they were then nobody would of gone to AMD, if Intel comes out with a banger than AMD will go back down to 13$. No value, just like their consumer products. AMD took a lot of risks, that’s why they came up in such a short amount of time, Intel is slowww they take their time, test test test. In the long run and for myself, I want reliability so I’m going to stick with Intel and NVIDIA, a couple good products in 3 years doesn’t mean anything to me, especially when they have all had issues.

DDR5's are funny.
