[SOLVED] Overclock Corsair Vengeance LPX 3600Mhz (Special case)

[troyer1234567]

hi, i said special case in the title because my ram is Corsair Vengeance LPX 3600Mhz C18 but due to lack of support by CPU it works as 3200Mhz C18 !
my spec:
Cpu: ryzen 3400g
MB: Asus b450m-a
ram: Corsair Vengeance LPX 3600Mhz C18 2*8GB
gpu: no gpu
psu: green 330W
here is the timings of my ram after i enabled XMP profile:

i changed 5 timing settings in the BIOS:
tCL: from 18 to 16
tRCDWR: from 22 to 18
tRCDRD: from 22 to 18
tRP: from 22 to 18
tRAS: from 44 to 36

other things are on auto but DRAM voltage is 1.35 (first i enabled XMP profile then saved and restarted and then changed these 5 settings i said, other timings are on Auto)
then did export my ram specs using thaiphoon burner and imported to DRAM Calculator and here is what DRAM Calculator suggests:

i did exactly what these settings recommend but after restart when i opened TM5 (testmemory5) and started the test, after some seconds it showed me the sad face error (your computer ran into a problem and...") then i went to bios and changed everything to auto but the 5 settings i mentioned above, i set them ro recommendations by DRAM Calculator which were 14-18-19-19-38 but again received the sad face error 🙁
now u can see my settings in the picture above (it's 16-18-18-18-36 and other options are on auto), it is fine and stable, did an overnight test with TM5 and got no error. i'm so noob with overclocking. just want to know should i change anything to get better result or not?

another question, i don't have SoC Voltage option in bios, instead i have VDDCR SOC Voltage option which shows 1.2V and has two options: A. Auto B. Offset mode
in DRAM Calculator it says the recommended SoC Voltage is 0.975, i don't know if VDDCR SoC is exactly that SoC voltage or different and wonder if mine is too high or not ?! in another thread someone said as i use igpu , it's ok to set SoC voltage to 1.25 so if he's correct then 1.2 is fine and shouldn't change it, right? (note: in ZenTiming software, VSOC (SVI2) is about 1.1V)

thank u for your answers

thank you man
one question: can updating bios help me oc my ram to higher freq? i mean, should i start testing different values again to see if i get better oc with new bios?

trials and errors. Overclocking is all about desire and luck. Like what i said way months before, if you're a diehard APU user, go 5600G/5700G, replace the ram sticks with something better, prolly a Team, V-color, Klevv, or PNY ram for budget.

Your apu cant do more than 3466 and 3600 at better bin. why 5600g/5700g? because they're IMC reached the mature of ryzen ddr4 development and ALSO its in an monolithic die WITH matured architecture + fab at 7nm TSMC.

OR if you do have a gpu now you could just buy a Ryzen 5500 which is basically 5600G with fused off gpu, and call it a day.

i've oc ed and fine tuned my friend 5600G to 4133mhz CL18 with tight subtimings with V-Color prism pro rgb 3600mhz cl18, and i bought the same ram as mine, did the same settings albeit a little bit tighter cause im on an intel system (i3 10105F) so y not? and its all stable.

the thing is to do ANY oc you would need:

1. Understanding about the chips, any chips. Cpu chip, gpu chip, ram chip, etc.
2. Know the motherboard wall frequency and bios wall.
3. Understand the way your ram chip behaves after stable overclock, like will it causes error at certain loads or temps.

and you're pretty much good to go.
