issue with ram

[Kumoko]

well when i try to OC using profile one 3600 which is the ram is rated at it gets unstable :/ is it becuase i only plugged in 1x8 of the cable for the cpu? 4 ram with 3600 it works with only 2 though

- BCLK 125.0

thats whats killing it

most you can do is about a 5-6mhz increase (105-106mhz) before killing the cpu

killing what? my cpu is fine and has been for 4+ years.

you can manually overclock the thing to 4.5-4.6, maybe more.

also the cpu never goes above 45c

I think "killing it" mean killing the chances it will work. From what I remember, the BCLK really doesn't take well to being too far away from the base 100 MHz; it's precisely why overclocking has largely been done through multipliers since Intel integrated the IMC (Northbridge and FSB went away).

OP, I may have missed it, but did you post your hardware anywhere? CPU-Z validation link, maybe? All I saw was that you're using a 3600X on an Asus B550.

One person's results do not equal what another will get, but in the rare chance I may able to give insight, I have a 3700X on an Asus ROG Strix B550-F Gaming and I have 4 modules at 3,600 MHz and it's working fine with me having done nothing but setting the XMP profile (interestingly, if I use half the RAM and set the XMP profile it fails). Our RAM might be different but I can show you what the voltages for things are running at. Also, I tried updating BIOS long ago and started having a random restart about two minutes after loading into Windows. It was odd, if I sat in the BIOS or passed that mark it was stable, but it was a Russian roulette game every time I started the PC. I'm not sure if RAM was why (it did this with XMP on or off by the way) but mentioning it in the off chance that different BIOS can have wildly different results.

But as the others said, if it works at stock 2133 MHz JEDEC speeds OR works at rated 3,600 MHz speeds with half the modules, the IMC voltage not being enough is a likely place to look.

and with the fsb/bclk overclocked, its also overclocking everything
+25% is a huge oc on ram and pci speeds etc...

oh i ddint mention my well overall specs ill just mention it on this reply
R7 5700G
4x8gigs ram @3600
my BIOS is also up 2 date
ye it actually works with 3600 with half the module only so 2x8 so is the IMC voltage the issue?
not sure at what config i should set that into though do u also have similar 3600 or higher ram that u r using?

3600+ MHz is difficult to run on more than 2 DIMMs at a time, even more so if it's below CL18.

When you add another identical kit, you need to use more DRAM voltage and more SOC voltage.

DRAM voltage can go up to 1.45~1.5V depending on the ICs used (i.e. Samsung B-die, Hynix CJR, etc.)

SOC voltage should rarely need to be higher than 1.1V and should never be set above 1.2V under any circumstances since you can destroy the IMC by using too much

Motherboard also has an effect; if the mobo's PMIC can't do 3600 on 4 DIMMs, then it's not going to pass, and that's the case for a lot of really cheap AM4 boards.

4x8 3600 running at cl16 (cl18 ram). The only voltage change is to the ram, which is at 1.37 (0.02 increase). The SOC is fixed at 1.1v, basically left untouched. Aorus Elite x570, when they were cheap.

Of course, this doesn't mean the same configuration will work on other rigs, even if the specs are identical.

oh wow 1.37 works i only set the DOCP easy mode then went to advance to change i think dram voltage n left everything alone it should b fine right it wont cause any issues o.o
