I'm running 4x8 bdie on 3800cl16 easily with c8hw and 5600x, same as on 3600x. On 2600x this kits was running on 3600cl14
Do you ha e updated benchmarks, Zen timings screenshots,etc?

I own a 2x8GB 3600 MHz CL16-16-16-36 kit and just purchased another kit to try it in dual rank 4x8GB.

My current timings are 3800 CL16 with 54.1 ns of latency. I'm hoping I can keep them but I know a few settings might have to be changed.

This is what it looks like in game, just doesn't budge from 3.7:



This is it when running benchmarks:

Your first CPU monitoring software reports the P-State frequency whereas the second displays the relative frequency.

Im about to return my asus strix b550e and bought a X570 Hero VIII for my 5900x cause im having random restarts since the start. What bios do you guys sujest to start from? I have 2 kits of 4000cl19 bdie. Hoping to atleast use it at 3600mhz.
uninstall asus ai charger

Well, got 4 sticks running at DDR4-3800 16-16-16 today. Won't boot with anything more than than that unfortunately, was able to do DDR4-4000 with 2 sticks (these 2 can do DDR4-4300 16-17-17 on Intel but can't do 14-14-14 at 3800...go figure) before but I guess this is a tradeoff.

last check for 2702 bios on ryzen 3950x it's seems to good stable, and performance is little bit better then 2402 i think, no whea errors or 41 kernel power problem. It's time say goodbye 3950x it goes tomorrow new home, and 5950x is arrive replace it. 3950x is very good processors i have little problems with asus bios and asus some how fix generally all problems but it need time.

i wondering i use der8auer custom oc brackets if they for 5000 series, i try because cpu layout is same compared to 3000 series

pbofmax on
scalar 1x
ovveride 200mzh
memory 3733 cl16
flck 1866

cinebench i get single score 545
and multi score 9660

cpu-z 568

I gave up on 2702 and stayed at 2502. I keep seeing Vdroops and massive frequency drops. I tried all the ways I could to get rid but they kept persisting. I dont see those on 2502.

This is it when running benchmarks:

It is as CyrIng states. One is reporting the base frequency, where as it checks once for stock output, and then does not update again. Hwinfo will update actuals at intervals.

For bios dump look at the last tab in the bios under profiles. The very last option will allow you to save profile and export them to either a text dump or CMO extension. That will save you making screenshots. LN2 mode comes under advanced options under CPU I think.

u have 3950x or 5950x?

3950x i dont see massive vdroop or freq droop different loads, its likely normaly boost behavior because my bench get more points and few fps gained

i currently use 3950x tomorrow i change 5950x because it finally come retailer and send it friday

Testing with "PBO FMax enhancer" to ENABLED, it seems to me to have better temps and higher mhz (with my 5900x, about 4950Mhz in single core), however my cpu Z in single and multicore is lower (580 NO-PBO FMAX vs 560 PBO FMAX on single, and 9700 vs 9500 on multicore). I don´t understand why if it seems better sustained speed and looking that option in bios it would be increase FPS, why the bench scores are lower? any tips?

Other thing I noticed I have good temps with default stock setting, reaching 72 degrees only with prime or fumark cpu-burner (all 24 threads, all cores, between 4200 and 4400 Mhz). However, if I do that test only with 6 threads, my temps goes to 85-90 degrees. Less threads and more heat?? I don´t understand why

it seems that while the clock is higher but the effective clock actually being lower, for it's 4.6GHz all core normal clock and 4.4GHz effective

What is the difference between effective clock and normal? If the core which is benched is at 4950 Mhz. Any explanation/help about temps issues testing 6 threads?

Just setup a new 5800X with (4x8GB) of G.Skill F4-3800C14-8GTZN running 1900MHz FCLK/MCLK 1:1. Currently prime blend stable, only enabled DOCP, set FCLK to match the speed and bumped vSOC to 1.0275 in BIOS.

Any suggestions on tightening timings without having to increase voltages significantly?

I've just installed a 5900x in my Crosshair VIII Hero and when playing games it won't boost at all and is locked to it's base clock of 3.7

If I run cinebench then it boosts just fine.

Is this just a bug?
That sounds very much like a Windows power profile issue. If the other suggestions don't work try changing this setting to 95% or higher (maybe try 100% to start):

I was getting slightly higher in single core at 5150 which occurred only a very few occasions. The Vdroop you can only see when you do all core stability runs. You will never see it with single core usage. I saw vdroop down by about .1v, and I couldnt find a way to boost it higher. Frequencies were hittings 2800mhz then skipping back to 4150s with intel burn test and aida 64.

RDRDscl and WRWRscl will give better latencies if you can find a stable set up by reducing those. I couldnt get mine below 4 even by increasing voltages. Use aida 64 to check out latency.

EDIT**
Nice site here for how timings work. Dont take it as gospel though. Use to find ball park areas.
