Still better than Comic Sans MS.
Game cache FTW
at 1440p there is no big difference at all (But still ZEN2 has notch better 0.1% LOWs)
Now imagine my system
3800MHz CL16-17-17-15-31-40 1T (63ns)
Finally a chance to see what 1004 is all about
Nice. That SMU is slightly newer than the beta bios for my ASrock B450.
WHY Meeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee MY 184.108.40.206B BIOS sucks, why am I cursed with low cinebench20 scores.Intel curse you.OH wait my gaming scores are good,my encoding is fast but frack it is not saying 5000Mhz why an I so cursed with AMD.NOOOOOOOOOOOOOOOOOOOOOOOO save me.
SMU... so power management, config etc... Maybe something newer for boost, voltages etc (not that I'm complaining)... sweet.
I do think they toned down the SMU aggressiveness in 220.127.116.11. Now I never got an ABBA to play with but I did have the modified ABB with what I think was going to be the ABBA SMU in it and it definitely boosted more often and for longer. I would still be using that one but the beta 18.104.22.168 works better with my memory so I'm sticking with it.
Totally! My current sticks are on my board's QVL (go figure) and yet weren't stable until this latest flash. lol. Ah well. Just glad I can use my rig now . I pretty much use most of the power conservation options and modes I can... I noticed one thing that's new on my board's PBO option now in this version. "PBO 45W Eco" mode...
Oh man do I hate this. I just took my crap-illionst try to get 120mhz bclk stable.
Voltage is OK.
Temps never rise above 65 degrees celsius.
Testmem5 runs 5+ loops fine without error.
1. I cannot get lower timings than CL14 besides using the 2666 strap to get to 3200mhz effectively. Shouldn't I be able to get it at least to CL12 something because using the lower strap? C6H does CL11.
2. My screen always gets dark after some usage. Because bclk oc I stressed all components at once with Testmem5 for memory, AIDA stresstest for GPU only, VLC with 4k video open and running a game fullscreen in the background while converting this 4k video to 1080p in different video/ audio format.
The screen went black, no sound, nothing, but a blinking memory diagnostic LED on my motherboard.
Any hints on what I could change? I heard CLDO voltage helps, but I don't know anything about that.
EDIT: rather... bear in mind - eventually you'll plateau.
Look for anything in your BIOS related to the PSU worded as or closest to "Power Supply Idle Control" within that Low Current Idle or Typical Current Idle choose Typical Current Idle. Low Current Idle is a compatibility/legacy feature, assuming yours is a newer PSU go with Typical. Low will also inadvertently cause undervolting in certain scenarios.
CLDO_VDDP is tricky. It's a cut between your processor sku and memory settings. For some overclockers/tweakers stability is aided by a voltage increase or decrease to this setting.
I'd still check this against your own testing but you can find configurations out there ranging between 850 mv to 1000 mv (that is unless your default is lower or higher for whatever reason).
Unless maxed out on all RAM DIMMs; verify you're using the recc placement of your Modules for the amount you have installed (consult your motherboard manual) if this is wrong it will screw stuff up.
Ehh the lower strap doesn't necessarily guarantee that. Hmm. Try different Command Rates, 1T, 2T, Gear Down Mode on / off.
The "UCLK==MEMCLK" and "UCLK==MEMCLK/2" settings can assist with memory stability if overclocking / tuning. MEMCLK/2 basically sacrifices some Infinity Fabric bandwidth at the flip-side of stability.
ProcODT is pretty well optimized by now but some have found fine tuning it to a specific frequency to stabilize overclocking.
You might want to save an OC profile before embarking on all this. Good chance you'll lock your system before finding the right combination.
Yes the 22.214.171.124b is toned down a bit on the boost part but I really do not mind at all if I boost to 4500Mhz or 4400Mhz.I play games 4K Freesync so the CPU clock is fine.
As far as memory goes, I have not had a problem on any BIOS setting memory up to CL16 4200Mhz ,weird thing I have not tried higher than 4200Mhz on the RAM.
I agree BIOS 126.96.36.199b is good enough and is a keeper and waiting for 188.8.131.52 now to come out.
First Beta BIOS vs 184.108.40.206b BIOS
Good morning all. Thought I'd add this link :-
MemTestHelper/DDR4 OC Guide.md https://github.com/integralfx/MemTestHelper/blob/master/DDR4 OC Guide.md#setup
found @ https://www.reddit.com/r/Amd/comments/dtnmtq/stock_cooler_ryzen_3600/
I found the amount of concise INFO on timings & relationships to each other very interesting & useful.
^ Man did time already flash that fast lol! *whew* holy gawd AMD has been burning the midnight oil eh
To be fair, that information is more helpful to the first and second generation Ryzen CPUs. There is a change in the IMC of the 3000 series. The basic rules are just that basic. What comes next is the unconventional and it is just trial and error, testing to see if it is an improvement or not. What has made me comment on it was the whole thing about not seeing an improvement with setting Trcdwr lower than Trcdrd. Cannot agree with that. There is an improvement; noticeable too. Mine is lowered as low as the bios allows 8. Bandwidth saw an uptick. Test Mem5 finished quicker as well. So there is an improvement maybe not in games but with other uses, there is.
Was premature earlier in saying that I found the timings I was staying with...until I finally dialed in the unconventional timings I am using now.
These are the results with the above timings and a cpu offset of -0.0875
These are the results with the same above timings and a cpu offset of -0.1000v
What Ryzen Master does not show is that Trdwr and Twrrd are both set to Auto. If Tcwl is set differently than CAS those two settings need to change to make it viable. Plus what is also not show is that those settings even when Tcwl is set same as CAS, the settings for Channel A and B are not the same when left on Auto. These settings gave me the best results both with singe core results but multicore results as well. CPPC and PSU idle control were left on Auto...do not like how the rig responds when those are specifically enabled.
Currently playing with the cpu voltage offset to see where the best compromise with the Vcore voltages, performance gains, and cpu thermals.
C6H OC with b-die. Probably useful for some, searching for values, limits and stuff.
Found on overclock.net.
In theory applicable for general ryzen oc.
The RAM strap thing is interesting. But you need external bclk gen AFAIK. Not much boards have that.
1440p Gaming Vs RAM LLT
Now we have a new beta bios too
sweet thanks for the heads up. I'm always excited to try out a new BIOS.... which is something I've never really said before I got my first Ryzen system.
Just loaded that BIOS and ran a Cinebench 20 lost 100 points on the multicore test single stayed the same. Same basic settings as I had on the earlier beta.
