pc not stable with memory oc rated speeds

I am having a real tough time with pinning down the problem of overclocking my ram. Importing ram data into dram calculator from taiphoon and trying both safe and fast settings haven't helped me. Have also tried xmp.

It's a problem that not even memtest picks up. Have tried leaving it going overnight and no errors. But gaming triggers it.

What would happen is about 30 minutes or so (sometimes less sometimes more) into a gaming session the pc will shut off, no bsod or anything and attempts to restart but never happens the fans keep spinning with a black screen. When the ram is at 3466mhz, the chances of a shut off happening is low. But at 3600mhz the chance of a shut off happening is almost guaranteed. At 3600mhz there will sometimes be a problem where sounds start crackling and become distorted while in a game.

 

Have tried playing around with voltages like dram voltage 1.3 to 1.4v, soc voltage went up to 1.25v

 

Specs : ryzen 3600 / tomahawk max / F4-3600C17D-16GTZR ram

750w PSU and I have tried another for troubleshooting still same problem. Tried multiple motherboard bios versions.

 

Here is what dram calculator shows me https://ibb.co/ZcTFMdK

What's your Vdimm?

Also, what sort of dies are on these chips?

Tried 1.3v-1.4v

Should be safe up to 1.5, but not all chips react well to raised Vdimm

But it feels like no matter what voltage i set the same problem always occurs

Could be a bad BIOS revision not actually raising Vdimm? Possible RMA, either MB or CPU.

Why not try lowering frequency and tighter timings? 3200CL14 works pretty sweet with my 3600. Does that work?

They are samsung b-die

Good Samsung B-die should do 3600CL16 and should react very well to raised Vdimm, up to 2.0V (not necessarily safe for daily). Also they react somewhat badly to high temps.

Is that faster than the kits rated timings and speeds?

Ohhhhhh, are the DIMMs in the correct spot? One set of slots usually give better OC headroom than the other due to slightly shorter traces.

Yes i have checked mobo manual and the preferred slots are 2 and 4

Not necesarilly. I thing the B450 Tomahawk has T-topology so, if he is using dual channel right, doesn't matter if it's A1-B1 or A2-B2.

Try this. Set everything in the BIOS to default, reset your pc and enable D.O.C.P., change Trc manually to something similar to 80 but a bit higher (82?) and see if that works.

 

Let the voltages and multipliers of the DOCP set as they are, don't touch a thing.

 

Sometimes, the Trc is set to auto but it's shown as a value.

If this doesn't work, I don't know...

 

I had a similar problem but with bsod instead of resets and it was that 1 of the sticks was faulty. It died few days after buying it and start having this problems.

 

Let's hope it's not the same problem with you.

What would this do?

Ohh, sorry to hear that :(

 

I only have one more idea.

 

Try to achieve something "similar".

 

Instead of 3600 17-18-18-38, try 3200 16-16-16-36.

 

Is not the same OC but is fairly similar while, at the same time, lighter on the ram.

Is there a big performance loss?
