With 3900X back to the original MSRP of £479.99 (new MSRP is £499.99 due to weaker pound), now is the time to make that upgrade, with some very tasty components indeed!

 

[Threepwood]

Very nice price on the 4400 there!

 

[RCM]

If a pair of these 4400 kits were paired up and downclocked to 3600/3733 (so as not to mess with the infinity fabric), what sort of timings do you think would be pretty easy to achieve without too much tweaking? Something like 16,16,16,36?

Any reason why you don't stock the 3733 Viper Steel?

3733 is not B die.

3866 upwards are B die and well I got the 4000 kits for less than 3866 so just made sense to stock the 4000 and 4400 models in B Die.

In theory the kits should down clock fine and if you get particular good IC than 15-16-16-35 can be possible at 3600 otherwise 16-16-16-36 or if again you get unlucky then 16-18-18-42 all at 3600.

Always remember to fine tune other sub timings too and use Ryzen master.

3733 is not B die.

3866 upwards are B die and well I got the 4000 kits for less than 3866 so just made sense to stock the 4000 and 4400 models in B Die.

In theory the kits should down clock fine and if you get particular good IC than 15-16-16-35 can be possible at 3600 otherwise 16-16-16-36 or if again you get unlucky then 16-18-18-42 all at 3600.

Always remember to fine tune other sub timings too and use Ryzen master.

Yeap, I realize 3733 is not B-die but as far as I gather it's the perfect speed for Ryzen, a touch better than 3600.

Still undecided whether to get some 4400 and downclock with better timings or just buy the 3600/3733 and leave it. Both the Viper Steel 3600/3733 have very reasonable stock timings and I'm really not into tweaking that much where RAM is concerned. The 8Pack would be better but I guess I've missed the boat on any deals for that RAM this side of 2020.

 

[Shac]

The 4400 Viper downclocks rock solid to C14 at 3600.
It runs exactly the same memory settings as my 8 pack set.
However the Vipers show as 94% quality to 92% for the 8 pack set.

Thaiphoon burner shows tighter timings from the Viper set though.

The none B die vipers don’t clock or tune as well.

Better of buying 4000 or 4400 Vipers and then down clocking them to 3600-3733 with as tight as you can make the timings.

Sick of procrastinating so will go with the Steel 4000Mhz. I'm not looking for uber fast timings and something like 16,16,16,36 will be great or even 16,19,19,39 is fine @3600Mhz (motherboard is an X570 Aorus Master). Not sure if I'm using Ryzen Calculator right but that seems to say those are possible using just its Safe preset (using Superficial's info from above). Not a major gamer and I understand timings make the most difference in games, so it's not essential to get every last drop out of the RAM. Thanks for your help.

I'm not experience at all but I got 15, 15, 15, 35 @ 3733 by just adjusting a couple of things so you'll be grand.

That's good to know, I'll see what it can do when the system goes together at Christmas. I'm not too experienced in RAM overclocking either so getting those timings with just a few adjustments sounds sweet.

These will easily do 3600 at cl14. The 8 pack 3200cl14 kits are a slightly lower bin and will all do this (cpu dependent I guess).

 

[Perfect_Chaos]

However the Vipers show as 94% quality to 92% for the 8 pack set.

Thaiphoon burner shows tighter timings from the Viper set though.

Where do you get to see the quality %?

[Danny75]

Got the cheap Patriot 16GB 3200MHz kit running at 3400MHz with same main timings and a slight touch up to 1.39v on the DRAM (XMP had it on 1.376v). 1700/1700 FCLK & UCLK. Not bad for what it is. Manufacturer showed as being "Nanya" in Taiphoon Burner (it's an older freeware version, may not be as good/accurate).

 

[Arne Saknussemm]

These are a no-brainer buy

I 9900KSs on the Gene ran these out of the box no tweaking

Still to test with Threadripper

You're possibly right but dram calculator shows my VS 4000 as 86% and my best settings as 3783 @ CL 16

I wonder if anyone knows if that is the safest bet or really my most reliable performance settings? I was running 3733 @ cl15 stable but I realisd my Tomahawk max onboard audio was crackling and popping - this was definately beause of my ram settings but since using Drams settings (properly this time) the beow is a far beter result than I was getting before:

 

[KungFuSpaghetti]

Oh really, 86%??? That doesn't sound right, just checked and my 8 pack show as 93% and I have had them running at 3800 cl16 too :S

I've read that the audio crackle is when you're running above the fabrics silicon quality, I would shoot for 3600 cl16, then try and tighten to cl14 if all goes smooth.

ok mate will try that cheers,

I'm certainly not done with experimenting but I *think* my aida benchmark results are pretty decent even at 3733/CL16

 

[KungFuSpaghetti]

Yeah those results im aida look bang on pal. Similar to mine
