FASTEST 32GB DDR4 RAM for Z490 & Ryzen 5000 Series - Overclocking G.Skill 2x16GB DDR4 to 4700+ CL18

Ok so I understand the difference between the 2 kits now, I thought the galax kit was 2x16 also for some reason after your community post the other day. I back ordered these. You sold newegg out tonite LOL. And im glad I didn't fall for the ballistix max 4400 2x16 kit, because I had been eyeballing that hard for a few weeks.

Wow after hearing 1.5 sa and i/o for above 4400....the IMC on my 9900k at 5ghz and 4200 cl16 32gb b die at 1.3v sa isn't bad at all.

[@marceldiezasch6192]

Have you tried Gsat on your daily stable 4700 setting? Gsat seems to be really hard on the IMC and can show errors even when HCI/Karhu/Prime etc didn't.

[@N0rth0M-1]

are all 2x16 kits b* pcb with 8 layers or are there better options? i got myself f4-4000c16d-32gtzr and that stuff is horrid at overclocking. they are horribly unstable at even 4200 with stock timings and sometimes even crash on xmp on the z590 apex, but when i use two of my 4x8 f4-4000c17q-32gtzr kit i can run them 24/7 stable at 4533 16161636 280 65535, it's weird.

How great would this work out of the box XMP for x299 EVGA dark? Any voltage changes besides dimm?

[@volodumurkalunyak4651]

tFAW below 4×tRRD_L doesn't do anything. Only if tFAW is higher than 4×tRRD_L memoty controller may add delay after 4 activate commands (each takes at least tRRD_L or tRRD_L cycles) for 4 above mentioned commands to take at least tFAW clock cycles.

[@UNDERGROUNDHITRADIO]

thats why i dont bother this 'overclocker'. all the other timings are loose as well. I can get the same or better with Hynix DJR or rev.e. nevermind dual rank b-die.

[@a36538]

Is 1.4 VCCIO and VCCSA fine for daily use on a 9900k?

[@c_cat0965]

I will let Luumi answer you directly but also give you some of my input. 1.40 vccio and vccsa are both fine for coffee lake as a daily, both buildzoid and der8aurer told me this, technically 1.350 is safe as well from what boosted media told me, however buildzoid told me that someone from intel confirmed 1.40 vccio and vccsa are both fine as a daily. Der8aurer told me that safe vcore, vccio and vccsa are about the same for coffee lake because the cores and IMC are made of the same parts and components and therefore the safe voltages for these values are pretty much the same as well. vcore can go up to 1.420 technically, so 1.40 is supposedly safe as a max for vccio and sa. - I personally ran 1.40 sa and io for about a month, and 1.40 sa and 1.350 io for another month or so without any issues, I stepped it down because I want to be on the safe side and run those higher volts when I get a full custom water loop and maybe do direct die cooling. @luumi What I am wondering if 1.450 sa and io would be safe on a daily for coffee lake, like 9600k, 9700k, 9900k? what about samsung b-die? can it handle 1.55, 1.60, 1.65 as a daily? - I know people that run around these voltages but they normally only been running it for months and I rarely ever hear of people running it for years and it's usually at the lower end close to 1.50 if they do run higher than 1.50 if they haven't ran into any problems, another issue is that these people tend to upgrade their builds frequently. if these voltages are not safe, e.g 1.55, 1.60 or 1.65, where would you set the absolute limit for dram voltage on b-die? and is that safe for imc and b-die IC in the long run? I am running z390 godlike.

[@basedanon420]

1.5v SA 1.4v IO even is fine for coffee lake.

[@wewillrockyou1986]

Which other kits have these updated PCBs? Or are these the same ones they use on the existing dual rank b-die kits with 3200 14-14-14 and 3600 16-16-16 timings? I know a few people who run flareX 2x16 3200 14-14-14 on AM4 and 1151v2 and those seem to be pretty good, they are also quite readily available in Europe... I do wonder what the addition of these higher end kits will do with the quality of those lower bin dual rank sticks though.

[@HyrrokkinX]

Hi Luumi i am currently testing the crucial 4400 on the Z390 dark.. will you ever try them ? i am bit disappointed... all timings go down like samsung b-die even lower some cases.. except Trfc of course.. but it is normal for hynix even the b-die.. the problem is they do not score very good.. . so far the best i achived is 4000 - 18 - 18 -36 1 T and 4266 - 19-19-42 2T, 100% stable.. tested on 2 different and good 9900KS... i am not sure but i feel that the 4000 kit at 1.35 is better basically at 4300 they stop working.. stable and at 4400 they do not even run xmp with auto settings, OS crash like immediately. (i know the main reason is due to being single channel) but other kit would have done some better though.

[@nubbins70]

Luumi what IC would you recommend for pushing the new Zen 3 CPUs' IF limits, while maintaining decent daily timings performance, all while keeping heat down? I have two AM4 builds in small form factor cases (Cerberus and M1), and GPU heat takes a serious toll on the DIMMs in certain games such as CSGO, which is a seriously limiting factor for B-die as even my 1.42-1.43V profiles on 4Gb E-die and DJR run up to 50C. And thats with a NH-C14S blowing over everything. DJR sucks at MT/s and Rev.E is loose on timings, but would you say instability comes on instantly at 50C on B-die, or do I still have a little room to work with at 1.4-1.45? Otherwise that would just leave me with the less temp sensitive Rev.E

You have to try it, some boards can do relatively decent speeds like 4400+.

I thought tRAS couldn’t be lower than CL+tRCD? So in this case 18+18 would be 36, but you run it at 34?

[@darrencoffey3377]

How does this new ram do on the z390 dark? My experience with older 2x16gb bdie kits hasn't been good and the max I was capable of was 4000mhz on the z390 dark just like you mentioned the z490 dark was before the new bios update. I always felt the bios was holding back the z390 dark with 2x16gb kits. 2x8gb can easily do 4600mhz on the dark, with a capable cpu however. Great video!!

[@LuumiJuhani]

Need to try. Single ranks go very high on Z390 dark as well.

[@darrencoffey3377]

I be really interested in your results on the z390 dark, I'm curious if the new versions of the 2x16gb clock better. I still think it's a bios issue on the z390, at least single ranks clock good.

[@arckie]

any chance you could share what timings for 3600 or 3800 to show what's possible on an AMD system? Wondering if it'll be able to hit 3600 C12 at 1.5v or lower? Or 3800 c14?

Need to wait for a bit before I can do some AMD testing...

[@arckie]

@@LuumiJuhani cool I appreciate it and the great video! I backordered these sticks on Newegg and plan to pick up Zen 3 at launch, but wanted to check what the experts were able to achieve with them so I’d have something to approach. Will you be able to test these on AMD before zen 3 launch or is that what you’re awaiting for? Thanks again!

_dd Timings can be set to 0/1 because they dont effect 1DPC Config. _dd is just for 4x DIMM Config like on 4-DIMM Boards. _dr is for dual Rank so you can set them also on 0 when using Single-Rank B-Die.

Man I've been overclocking 3000 megahertz dims to 3800 at 1.2 volts S.A and I.O I figured 1.25v was the highest I could go based off previous videos from coffee Lake so 1.4v should be okay on a 10700k as well?

[@barrywuthrich8530]

That is interesting. I think my old Lenova ideapad y580 (2008) has memory sticks about 1/2 that length. It has 8GB Ram. Is there a double sided memory available that would kick it up to 16, or would the i7 core processor not benefit from it? I'm obviously not a techy person.

[@randomchars9619]

somehow it feels that you mix up double sided with dual rank here and there. eg in your intro, where you use both terms w/o pointing out that dual sided doesnt necessarily means dual ranked. the performance comes from beeing dual ranked. p.s a link the the oher ram vodeo in the description would be some nice accomplishement of ahead-thinking ->qol thing :)

The manufacturer of the memory is Samsung (Or Micron/Hynix), all of these just stick them on the DIMMs. There's little to no difference between "RAM brands"

Actually you can preorder this kit in memoryc site. Is it safe to buy there? www.memoryc.com/memory/f4-4266c17d-32gvkb.html

I have the 4000 version of this kit. It will do 4400 1.5V 17-18-18-38-520 2T with my 10700k and Asus Z490-E Gaming with 1.3v SA and IO. Any ideas on what to tweak to improve this? It doesn't seem to want to post past 4400 no matter what.

Great video, and great sticks. Just ordered one set. Is 4800 with dual rank sticks harder for the IMC than 4800 single rank ? I mean, can your IMC pass HCI with 4800 single rank ?
