Downclock 3600Mhz DDR 4 for b450

Recommended Posts

Posted · Original PosterOP

Hi. I have a spare pair of Corsair vengeance lpx 3600mhz ddr4 2x8gb sticks, and was thinking of upgrading my editing pc using these.

Issue is I'm going from an i7 4790k to a ryzen 7 2700 and an asrock b450 itx board, or maybe the msi itx equivalent.

Is it possible to manually downclock the ram to 3200mhz, manually set better latency and timings, so that it will run within spec of the b450 boards? 3200mhz is the sweet spot for those boards apparently.

Yes.

I downclocked my DDR4 3466 to 3200 manually and set the CL from 16 to 15.

 

but why didnt you buy the fitting RAM from the beginning?

Yeah i thought so but always best to seek a definitive answer. Thanks.

Its spare due to upgrading my Ryzen 3000 gaming pc with the g.skill ripjaws v memory, which was purchased for half the price compared to when i originally built the pc. Saw the black Friday bargain and upgraded😁

Yes you could, even without manually adjusting timings if you wish so. Just force a lower frequency with DOCP enabled

Ah, that makes sense.

 

Good luck and have fun with your build.

Yeah sounds good.

While you can downclock from XMP setting, you maybe just able to run it straight at its XMP settings to be honest. If the XMP is faster than 3200, then it won't effect anything badly (particularly if you aren't going to change other timings), it's just runs in to the law of diminishing returns over 3200 apparently. I have 2*8 of GSkill Trident Z Neo in my B450 board with a 2700X, and it has zero trouble running at XMP of 3600 CL16 out of the box.

So these sticks now come clocked at the advertised speeds right out of the box, as in, no need to mess with the xmp etc ?

 

I was under the impression all of them have to be manually set to the desired config.

You still have to enable them to run at XMP in the bios, and some will/some won't, particularly on Ryzen 1st & 2nd gen. The Trident Z Neo I have worked out of the box, once XMP was enabled in bios at 3600 CL16 on a 2700X. Sure, I might eventually tweak the timings etc down to CL15, maybe 14 if possible and some of the other timings, but tbh, it's running stable rock solid on the XMP profile and isn't doing anything super latency dependent so I'm not bothered at the min.

Well that good to know and hopefully i can just plug n play. If not then at least other options are possible. 

I shall report back once up and running.

Cheers
