My RAM won't OC. At all.

[linum]

I have a set of 2x 8GB GSkill Trident Z RGB 3200 CL16 (part number ends with GTZR). This thing won't OC at all, won't even let me do slightly tighter timings. 

 

It's paired with a 5600X and a B450 Tomahawk MAX. It's supposed to be B-Die - but did I get a crappy chip wrapped in fancy metal?

You could try upping the voltage as well as timings, maybe it just can't get enough power

However upping voltage can cause your memory to degrade faster

I've tried 1.4V on it (stock is 1.35V). No good. I'm tired of resetting CMOS because every time it fails to post.

I actually got best results by first picking XMP (or whatever it's called for AMD) and then changing only the clocks. 3200 MHz is a bit on the low side for Ryzen 5000 series tho. You should really pick a 3600 MHz kit from the beginning as that's where you get the biggest gain in performance which starts to drop again at 3800 MHz and over in most situations. Especially since prices are not that much different really. Depends where you live tho.

 

EDIT:

Btw, since you have Tomahawk which is MSI, look for "Memory Try It" selection in BIOS. I think ti should have it. There are bunch of predefined profiles. When I had MSI board, that actually gave me best results. Where picking things manually so often failed.

How did you come to the conclusion that it's Samsung B-die? 3200 CL16 is literally the most common DDR4 bin out there at the moment, and kits rated for those speeds can be almost any DDR4 IC under the sun.

 

If it really was B-die though, then that doesn't necessarily mean that it should overclock well. There's good B-die (3200 CL14 kits and such), and then there's bad B-die scattered around other random speed bins or even OEM JEDEC sticks, though they're fairly uncommon.

That depends on the memory IC being used and what voltage we're talking about.

Yeah, temperature too. Personally I don't overclock my RAM as I don't game anyway (mostly productivity with me) as I don't want to risk it dying as I have only 1 8GB stick rn (awaiting another from AliExpress).

Tried Try It as well, same thing, fails to post. Even at same speed, tighter timings.

Thaiphoon Burner is where I checked the SPD properties.
