[SOLVED] Overclock my G-Skill DDR-4 F-4-3200C16-8GVKB

[qnkov]

Hello there. Using MSI mother board 550M with kit 2x8GB of G-Skill DDR-4 F-4-3200C16-8GVKB. I just overclock my ram from 3200 (16-18-18-18-38) to 3600 with timings 17-19-19-19-41. First I've tried 3600 with 16-18-18-18-38, but after reebot it crashes. Is that good timing and clock or should I change it?
When I check it with hwmonitor is like this - https://prnt.sc/18rrl1l

Model of your MSI B550 chipset board? What BIOS version are you currently on for your motherboard? Did you change the voltage on the rams before you tried tightening the timings and increasing the frequency? Speaking of which, what voltage are you on at the moment? Processor used on that board? Try taxing the system with a game and if see if the overclock has helped with gaming and benchmarks. If they're unstable, you will need to tinker more with the timings.

I'd try with 3600MHz, 1.4v, 18-18-18-18-41 then dial the timings down gradually. With the timings dialed in, see if you can drop the voltage down to 1.35v and test for stability.

"Is that good timing and clock or should I change it? "

You should be able to tell us.
Tell us: Did bandwidth increase? How was latency affected? What programs did you run to check stability?

My spec:
Cougar Mid-Tower - 5 Fans | MSI B550M VDH - PRO WIFI | Ryzen 7 3700x | RTX 2080 | 2x8GB G-SKILL 3200 | NVME 250 GB - Windows 10 | SSD 500 GB EVO 960 - Gaming | 3 TB USB SSD Disks

I dunno about bandwidth or latency, even dunno what is that. Yes, voltage is 1.35. I didn't even test it. I just ran 2 games at same time and everything was ok.

So, i've set it 17-19-19-19-41, but for some reason CL goes 18., so its 18-19-19-19-41. You suggest me to try with 18-18-18-18-41 on 14 v? I've tried with 17-18-18-18-41 on 13.5V, and i needed to restart the bioss, cuz the computer didn't want to startup. And that takes time, cuz my batter is under my video card ... )

Aida64 will tell you bandwidth and latency.
HCI Memtest to test stability, most of your RAM, leave 4-5 gigs for Windows. Run to at least 100%. A quicker test is Testmem5. But not as thorough so can't trust on that alone. Good to use while dialing in timings.

https://download.msi.com/archive/mnu_exe/mb/E7C95v1.7.pdf Page 38. To reset CMOS, rest something metallic on those 2 pins for 10 secs. Screwdriver is popular.

Geardown mode enabled will make your CL go to nearest higher even number. But CL will alternate between 17 and 18 in your case. It's how GDM works.

Hi, i just started the HCI memtest 120 percent - no errors and stopped it. I've installed memtest86 with flash and started it, but i've notice that in RAM INFO there is my ram with XMP profile 3200 with 16-18-18-18-36 timings, but not with my overclock freq and timings? The test runned for 30 mins, first PASS and i've stopped it. No errors. But does that means that i'm making test on my xmp profile with 3200, but not my overclock custom settings?

When your timings didn't work, mobo probably reset them.
