Looking for some B-die for a new 5950X build.

Got to be 2 x 16Gb sticks but what’s the fastest and tightest RAM I can get away with on a Strix X570-F Gaming mobo?

Loved the 8Pack kit I’ve used for 2 years on my 2700X but I’m a little out of touch with RAM right now but gather the new Ryzen’s love good RAM as much as Zen+.

Anyone able to confirm if these are about as good as it gets for the Ryzen 5###’s?

I can see a few 4 x 8Gb packs but my understanding has always been unless you needed quad channel RAM, you were always better off getting two sticks only, if only for stability when overclocking. Is that no longer true?

Great RAM, @Guest2 is running these at 3800MHz C14 :eek:

I'm sure he'll be along soon to share his sage like advice :D

As far as XMP goes while still being relatively safe for FCLK: F4-3600C14D-32GTZN

3600 14-15-15-35 at 1.45v

The 8Pack RAM at its current £260 asking price is too much. At £199 fair enough. Also yes as you stated above go for 2 sticks over 4 unless you really need to start going over 32gb. Even then 2x32GB would be advised.

My advice was all taken from people in this thread - https://www.overclockers.co.uk/foru...-to-8-pack-ripped-edition-32gb-kits.18885405/
The likes of @MrPils and many others. As other have said in there, it's probably not the best idea just copying my settings without understanding what the different settings so. There are some great pointers in that thread on what the settings do, give it a read (not you Space Monkey, anyone)
A sticky with some useful memory overclocking info would be a nice to have - things like what the different settings mean and do, programs to use like Thaiphoon, ZenTimings, DRAM-Calculator-for-Ryzen, AIDA64 and TestMem5 and general information

It seems a lot but can you (anyone) point me in the direction of some RAM that clocks to 3800 CL14 for the same price?

From what I can see RAM like the 2x16GB G.Skill Trident Z Neo F4-3800C14D-32GTZN is £350. G.Skill Trident Z Neo DDR4 3800MHz 4x8GB (F4-3800C14Q-32GTZN) is £500

I know the 8 Pack kits is not guaranteed to run at 3800 CL14 and other kits may run at 3800 CL14 which are cheaper but still.

Gskill have a 3600/14 32x2gb kit but they're probably a bit pricier than the 8pack stuff But realistically unless your gaming at 1080p or running a specific application that benefits from tighter ram speed/timings you would be hard pushed to notice a difference between 3800/14 and 3200/16.

Well I’ve had 3200/14 running at almost 3300 for the past two years on a 2700X so I certainly don’t want something slower.

Just want to do the same with something suitable for a 5950X and not 100% sure that the sticks I linked to earlier are the correct ones or not.

Right now I have great confidence in G. Skill supplying the best chips. They quietly stopped manufacturing of the 3600C15 1.35v bin just before the 5000 series Neo RAM was announced. I am more than certain they are simply using these chips in the Neo since they can charge a premium for them. The 3600C15 bin is close to the best chips made.

Still it's very hard to state what speeds RAM will do when overclocked. For example if you were to buy another set of 8Pack sticks you might not be able to reach the same timings or maybe you can get away with lower voltage. Tom's Hardware did a review of the G. Skill 2x16GB C16 bin and they reached 13-14-14-35 at 1.45v: https://www.tomshardware.com/uk/reviews/gskill-trident-z-neo-ddr4-3600-c16-2x16gb-review

It's not beyond the realm of imagination to expect an increase to 1.5v would allow +200 Mhz and something like 14-14-15. That kit could be snapped up for £219 recently and addition of a temperature sensor was an added bonus.

Thinking about it I wouldn't be surprised if the whole G. Skill 5000 series is the exact same chips just with voltage changes in place to reach the required spec.

Still when talking about RAM of this spec they are all probably very close (within 5%) of each other regardless if you go for G. Skill or TeamGroup offering. Just get what is readily available and in stock.

Why dont OcUK sell the trident Z Neo? All their Gskill RAM is out of stock, maybe just trying to shift the 8 Pack RAM instead :confused:

Yeah no point stocking 2 high quality RAM brands that would likely compete against their current TeamGroup offering.

From looking around before the g.skill 3800 cl14 seemed to be the fastest ‘base spec’ 2x16gb you can buy but I can’t vouch for infinity clock or timings. That is with a voltage of 1.5 mind, so perhaps little headroom to push it further.

Probably just well binned versions of the same batch of chips from ‘lower ranked’ sticks.

Well I’ve scoured high and low and can’t find these or something similar anywhere. :(

Anyone ever spotted these in the wild? Or an OCUK equivalent?

Just want to make sure I’m getting the best RAM I can for my new 5950X build.

Any suggestions please?

Money is burning a hole in my pocket but don’t want to buy the wrong product. :(

Not what you want to hear but waiting is a solid option until prices and supply are at decent levels.

Going for "best RAM" can't really be quantified. There are way too many variables in this. Technically that 3800 RAM you linked would be close to the best if not the best but then again you can argue it's not because 1: You can't actually buy it 2: If you don't have a CPU that can do 3800, the RAM will lead to an unstable system.

The safest RAM eliminating CPU I/O die would be 3600 with 14-15-15-35 timings but again good luck finding it in stock.

Yeah, fair points. However, if my 5950X can’t do 1900 IF then it’ll be fine for 3600 instead but with tighter timings, least that’s my understanding.

There’s got to be some 3800 CL14 2x16Gb kits out there somewhere!

Lots of great advice

Thanks for that. I've got the same RAM as you and honestly, the only thing I've done with my machine is turn on XMP.

Do you have an XMP vs your current settings benchmark for comparison please? If there is a chance I can get C14 @3800 I imagine that wouldn't be an inconsequential performance uplift

I have screenshots of XMP Timespy /and AIDA64 as was mainly looking at lowering latency with CAS14

This is XMP

Timespy was around 12300 CPU score using XMP - https://www.3dmark.com/spy/15401933

DDR3800 / IF1900 / CAS14, around 13000. PBO left on default (auto) with both

awesome, thanks.

Do you mind me asking what settings you have on your RAM as an indicator ? (Voltage, all the timings, etc? )

Those numbers @Guest2 are pretty poorly optimised, the write speed is appalling unless that's just a Ryzen thing?

I'm running some of these now: BL2K16G36C16U4B Crucial 2x16GB Single Rank.

Some initial tests:

3600-C15-1.28V
3800-C16-1.31V
4000-C16-1.34V

After some optimisation I'm now at 16-18-18-38, with very tight sub-timings, generating the following on a 9900K with 1.35V (average of 5 runs as they vary a few % run to run):

Read: 56.6GB/sec
Write: 57.8GB/sec
Copy: 53GB/sec
Latency: 39.6ns

These sticks seem to respond well with voltage, so I'm sure 3800 C14 is also possible but as I'm not looking for absolute peak performance 4000/C16 at 1.35V seems solid enough.

I recommend using: https://github.com/integralfx/MemTestHelper/blob/master/DDR4 OC Guide.md
