[SOLVED] 3600 Mhz ram works at 3200 Mhz even with XMP enabled ?

[troyer1234567]

Hi
just bought a couple of Corsair Vengeance LPX 3600Mhz CL18 Ram Sticks, and installed on A2 & B2 slots of my Asus Prime B450m-A, my cpu is Ryzen 3400G
in BIOS, there is an option called "D.O.C.P" which is XMP , i've enabled that and selected the only available profile which is 3600Mhz Cl18 1.35V
when i go to AI Tweaker tab , there is an option called "DRAM Frequency" which got set to 3200 Mhz after i enabled the DOCP profile. when i change it to 3600 the system doesn't post and i have to go to bios and change it to 3200Mhz, i haven't checked other freqs like 3400Mhz
any solution?

Firstly, check the timings. maybe it's at 3200mhz cl16 which is basically the same as 3600 18
also, recheck if there are multiple profiles, there should probably be.

It might also be just the cpu not being able to go up to 3600. older ryzen chips tended to dislike higher frequencies.

checked the timing, it's 18
and there is only 1 profile

The 3400g is part of the Zen+ architecture. Those chips tend to top out at around 3400MHz on the Dram. Make sure you have the latest motherboard bios compatible for your cpu, it may help. If that doesn't help. Fisrt load the DOCP and then try lowering the frequency down to 3533 then 3466 then 3400 etc. and reboot at each frequency until you find the max your system is going to support. I have a Zen+ cpu that wouldn't boot above 3466 just using DOCP. With a lot of time, trial and error I did get it running at 3600, but for what was likely a very small performance gain it probably wasn't worth the effort.

wouldn't it damage my system if i change frequencies and check whether it works or not?
what's your cpu model?

 

[bfollett]

It's not going to damage your system to use a lower frequency. The ram is rated to run at 3600 so any frequency lower than that (such as the 3200 you are currently running at) will be fine. I have a Ryzen 2600x which is also a Zen+ CPU. Even though your CPU is numbered in the 3000's, it is not a Zen 2 CPU such as the 3600. AMD seems to always use the previous generation core in chips with integrated graphics such as your 3400G.

i've heard that changing ram settings in bios can hurt controller in cpu and damage cpu

If you do extreme RAM OC and really overdo it, it might do that. But under normal conditions and if you don't do anything crazy, it usually won't, no. I'm pretty sure a 3600MHz kit that is essentially mainstream (most sold in my country, actually, taking someone who works for the biggest PC parts retailer here by their word) and also especially tuned to Ryzen chips according to Corsair's page shouldn't usually do that.

Btw, I use the same RAM kit with 32GB and a 12700K. It's a pretty decent kit.

how can i use my current kit with current speed (3200) but with lower timing (CL16) ? because i had two options when i went to store :
A. 3600Mhz CL18
B. 3200MHz CL16

i bought and now it works like B but the timing is not 16 , it's 18. can u help me to make it work as CL16 with 3200 Mhz freq?

Unfortunately, I never tinkered with that. It should be a setting in the BIOS, though. However, absolutely do some research about the timings a 3200 kit of this type has. CL isn't the only timing that will be different. I had no issues outside an XMP glitch with my RAM kit, and the glitch was solved by resetting to factory optimum values, so I didn't have to look into how to change anything...

 

[bfollett]

You should just be able to override the CL to 16. The ram should handle that without a problem.

if you want to tune it yourself, you could give zentimings read and thaiphoon burner read and post both screenshots here. Prolly i could help. Also tell which ver. are your corsair sticks, it's on the ram sickers itself, on right side under barcode. for 3400G, 3466 is attainable at CL16 with some tweaking, 3533 might be attainable too.

ok thank u so much i will check that

but does it really worth it to change everything to get freq to 3533? i play games with my pc

I could help with tuning it, just need the infos i asked.

Also yeah, wether you use the igpu or not, ryzen does love faster ram and lower latency since how infinity fabric works. Heck even a 5600G at 3600mhz ~ 4000mhz+ at CL16~CL18 does perform near close to RX 460. 3400G is mostly at 1030 level, with good speed and timings.

only difference between slots is tRDWR and tWRRD i think

ram ver is 5.30

Probably your ram are hynix CJR, or a good bin AFR (cant clock more than 3600 stable).

Here is my recommendation:

• Update bios to bios Agesa 1.2.0.3 (dont go above it since it got bugs)
• Install the latest chipset driver ver 3.10.22 on your mobo web page and reboot
• Try these timings and settings (start from the biggest value first):

Dram Freq: 3200~3466/3533 (make sure voltage is applied first)
DRAM Voltage: 1.36v ~ 1.41v max (prolly just do 1.36/1.37)

SOC Voltage/DVID Voltage: 1.1~1.15v (usually 1.25 max is fine since you're on an APU which needed for igpu power, if your not using igpu you could just do 1.15)

VDDG CCD and IOD (or search anything with VDDG voltage): 0.950 or 0.955v. (usually it's -0.04v lower than SOC, dont go past 1.1)

VDDP Voltage: 0.945v or 0.910v (usually it's -0.04v lower than VDDG)

FCLK Frequency: Auto

UCLK Div1 Mode: UCLK==MEMCLK (or leave it auto since you're using Zen+)

Primary Timings:
Command Rate:Gear Down Mode or 1T, just make sure Gear Down Mode is enabled, or 2T with gear down mode disabled
tCL: 16
tRCDWR and RD: 18 or 19
tRP: 18 or 19
tRAS: 36

Secondary Timings:
tRC: 55 or 56, or stay at 60+ (just below 70) if below 60 cant do stable
tRRDS: 4~6
tRRDL: 4~10
tFAW: 32 or 24 or 16 (usually 16 is attainable)
tWTRS: 4 or 5
tWTRL: 8~14
tWR: 16~22
tRFC: 630 or 560
tCWL: 16

Teritary Timings:
tRDRDRCL: stay at 5 or 4
tWRWRSCL: stay at 5 or 4
for SCLs, sometimes 5 is better performant than 4 due to instability, you could compare it yourself using aida64 memory and cache benchmark.

tRDWR: 8
tWRRD: 3 or 2

ProcODT: 43.6 or 48 (start from 43.6 first)

ClkDrvStren: 24
AddrCmdDrvStren: 24
CsOdtDrvStren: 24
CkeDrvStren: 24

Gear Down Mode: Enable (if it cant be changed, leave it be auto) or Disable if use command rate 2T.
Power Down Mode: Disable
Dram Latency Enhance: Enable (if such a feature is available)

Then test them using this TM5 with absolut config, open tm5.exe, click on load, choose absolutnew.cfg, then reopen tm5.exe as admin, wait till 2~3 cycles passed. If there is any errors after 3 Cycles, share a screenshot of the tm5 and let me see which errors you got the most.

thanks forhelpin me , i'm really noob to this overclocking and just worried , would these testings hurt my pc?

Edit: i found out what that Aesga mean and checked my bios , its version is 3122 and Agasa 1.2.0.3 Patch C so i shouldn't update it to Agesa 1.2.0.6b right? i should change my bios.

here i read that my ram sticks are AFR: https://forum.corsair.com/forums/topic/142851-what-is-the-difference-between-ver-431-532-539/

another question, can i install Agesa Bios on my Asus b450m-a bios? where can i download it from?

- No, it wont hurt your PC since the ram rated specs are 3600 C18.

- dont worry much to find agesa bios, every amd bios utilize agesa since it's their codes. just find the one that does have Agesa 1.2.0.3 if available, or 1.2.0.2, find your bios here

- If it's a hynix AFR, then this is a ok bin (since afr does not OC well, just a little bit above MFR), 3433 should be the max usually Zen+ could do, if you're lucky, you could do even 3533.

even if i increase the voltage to 1.41? shouldn't i be worried?
i have no cooling system but the stock fan of cpu

 

[Koekieezz]

It wont hurt. but i suggest just use 1.36v or 1.37v since AFR does not scale too much with voltage.

i only found DRAM freq and voltage setting in bios:

and also there is an option called DRAM Timing Control, i can control timings there but there is no option for VDDG or FCLK or UCLK

btw i increased dram voltage to 1.36 as u can see the ram freq is at 3433 and system post well. the xmp is disabled and cl timing is 24 which is awful

well i already posted the timings i suggested and you could just read, mix and match which is which.

for fclk just leave it be, and let vddg and vddp auto. For SOC Voltage you could use GFX core voltage instead of VDDCR SOC Voltage (or you could use vddcr soc and see if it stayed on a fixed voltage.), you could just do 1.15, or 1.2v if you do OC your IGPU. also your CPU Voltage is high, bring it down to 1.35 or just stay below it if you could.

are you on bios with agesa 1.2.0.3 yet?
