New cl26 DDR5 RAM for Ryzen coming in January.

Im currently seeing if i can CL26 on this kit with a slight voltage bump.

If not i’ll bump the Transfer rate instead

Its pretty darn good! Very snappy at these timings.

Let us know how you get on.

Passed Testmem but I want to try the OCCT test later.
I did play cod for a good few hours the other night and this really hammers all the components in the rig at 4K and had no issues at all. It really was a blast, performance was brilliant. :)

Did try 1.35v with errors so bumped straight to 1.4v with a complete pass a few times.
I guess I'll leave it at 1.4v - max temp was around 50c with no issues.
4x Low rpm 140mm fans as intakes as everything else is water-cooled with external rads so this helps.


 
So sub 60ns is possible. Newish OS install shaved about 2ns off.

Happy with the timings below, TM5, Karhu and Ycruncher seem stable. Overnight Karhu left to do before I can leave it alone as a daily profile.

CL28 - 6000Mhz - Seems to working very nice.
Still a few adjustments I can make to the tertiary timings which may improve latency but so far happy with this kit.

 
Personally I just find the fastest and buy it. Yes it's 0-5% difference typically. But I'll also buy pre overclocked graphics card to go with it, so that's another 0-10% depending on the game etc.

I don't upgrade often, so when I do, I'll stretch the budget a bit too get beefier hardware. Spending an extra £100 on a build can make it last that little bit longer in terms of performance.

I'm still on my 5800X, watching these newer DDR5 kits closely. :)
 
Been keeping an eye out for the CL26 that was “Pre Order” until a couple of days ago, and now they have been taken off the site completely.
 
realised yesterday what a difference with (my sticks of 6000 A die) volts wise 6200 cl28 vs cl30 is

6200 cl28 - VDD 1.43 and VDDIO 1.35v
6200 cl30 - VDD 1.32 and VDDIO 1.27v - with even tighter timings

going to stick with cl30 as at 1.43 I was noticing that I was approaching 60C under test and then failing test due to errors now temps have gone up a bit with the increase in ambient temps

I think this is really good insight into how difficult and fiddly memory overclocking can be.

Yes, you can get more performance but it's not a case of 'timing setting go lower, performance go higher' as many people think.
