3600 cl14 bargain

some of these low latency sets may be A2 which is currently faster than B die on intel.

Memory checker says mine is samsung, but it does not say B-Die. Spec sheets say all above 4000mhz is B-die tho.

Got mine to post at 3733/1866 if cl 14 @ 1.49v unstable so I will up the juice a little. Have to manually enter VDDg/vddp as no post on auto. That is on any timings or speed. Strange issue with bios I think as I cannot enter any value below 1v on either.

NicE! Have you stablised yet?

Did not have time last night but it looks like more volts will do the trick. Hoping for a new bios update soon.

My 4400 kit is Samsung B die and is down bin? 94% quality though.

However it runs tighter timings than my 8 Pack 4000 kit.
No idea if down bin is considered good or bad though.

Just posting to let anyone interested know that the patriot viper steel series ram (4400 cl19) is amazing value. I paid £130 for 2 x 8gb. I presumed it to be a quality set as it’s rated at 4400mhz with good timings. Running error free at 3600 14-14-14 with all timings suggested by the calculator. I dropped the voltage from the suggested 1.45 to 1.40 and still rock solid. I did not want to pay the increasingly ridiculous prices for gskill.

Thanks very much for the OP I just bought 32GB, it's brilliant stuff. £260 for 32GB 4000mhz DDR4, I'm running mine at 3000, 12/12/12/32 will be using it at 4000mhz or close in new build!

No probs. Wish I had got the 4000 instead as it seems like the same stuff!

Which kit would that be as i am in the look for a good ram kit for my ryzen build. Is it 4x8GB kit or is it 2x16GB and would you have the product code by any chance ?

Been having fun with this kit, as promised here are my own results.

I did see slightly over 37GB on maxmem with 3800 cl13 T2 but that needed 1.65v and there was a prime95 error within 10 mins, I think it might be stable with more V, but not today.

For now I'll stick with the 16's 1T @ 1.4v 3800 as a daily while I think about how comfortable I would be with the others! With a little extra ram cooling I dont think i'm afraid of running 1.53v as a daily.

Here is my result with the 8 pack dimm set, for reference. My experience with the 3200 C14 kit has been excellent and i would personally avoid higher latency kits from Patriot or Group unless they are hand binned in this manner.

I tried 4500C19 but was slower yeah, i would say that somewhere around 1.55v-1.6v depending on vdroop is the max on two dimms without active air cooling. I have not tried 1T will give it a whirl tomorrow.

4x8GB will check product code and let you know, here it is

I don’t think the higher latency higher frequency patriot kits are worse than the 8 pack. The cl19 is @ 4400 1.45v. They scale down to 3600 c14 comfortably, albeit with a little Voltage tweaking. With a decent board/cpu 3800 c14 is doable and for us Ryzen users, that’s a holy grail figure with an IF @ 1900.

I'm looking to upgrade my 3200cl16.
Any advice between 8pack 3200cl14, patriot viper 4000 or viper 4400?

Well, it wouldn't boot with my IF at 1900 with this memory.. weirdly enough but 1866 is completely stable with the xmp 2 profile at 3866 memory. I wonder why with my old kit are stock settings 1900 was completely fine but yea. I'll have to see what timings i can get now.

I have no experience with the 8 pack but people have had good results with both. The patriot will do 3200 cl12 according to one user, and if your a Ryzen user 3600/3733/3800 cl14/16 depending on your board/cpu. I can only get 3733 cl16 or 3600 cl14.

I have only tried this ram, I have some old 3000 Corsair I could try but the stock timings are bad and tbh I’m happy with these. I had no luck with the xmp profiles and went full manual timings/voltage. Threepwood has had his running 3800/1900 if cl14, so he may be able to give some advice.

Try upping the SOC Voltage to 1.15v and VDDG at 1.10v Edit: You know it can do 1900 but it probably had an eaiser time of with with low speed ram and not being in 1:1, I reccon you just have to up them volts until you get there! Good luck!

Hey! Nice score and ty for the reference! That'll be you in 5th place there now right! Pesky low 3700x write speeds!

Well, those two settings appear to let me boot into windows at least!. It's time to do some testing..

btw is 1.15v safe on the CPU SOC?

Yep, 1.2V is the upper limit of safe SoC voltages!

And, nice you are in! Is that with the 'try it' cl18 settings?

Yeah, that's with the secondary XMP profile! I now have to adjust the timings but a little skeptial as there are bio updates all the time!.

P.S Ermm, bit of a silly question but when i try to import the XMP profile tells me i have not clicked the show in nano seconds bs yet i don't see the option for it..

Threepwood · 5 Oct 2019 at 14:26

No idea on the nano seconds mate!

Fwiw, I would download the ryzen memory calculator and get aquainted with it, click the r-xmp choose B-die, 3800 then use all the provided settings from all pages, not just the 1st page sub timings and all then work from there!

Edit: But bump the suggested voltages, you can try reduce them later.

Ha, i click R-XMP and get nothing but yeah. i agree about the voltages. It's all about fine tuning. It's a shame you can't save all the subtimings/work when you have to bio update but i suppose it gets easier/faster the more you do it
