FEATURED G.Skill Trident Z RGB 2x8GB DDR4-4266 CL19 - F4-4266C19D-16GTZR

I actually started tests of this memory but still wanted to post this thread and will keep it updated till I finish tests. I guess I will keep this memory for longer so you can expect some more results in time.

As all can expect this memory is based on higher binned Samsung B-die. Pretty much can't find anything better for overclocking right now. It's also so popular IC that I will probably skip some tests as you've seen it in my other reviews. At least Trident Z 3000 CL14, 3200 CL14 or 3600 CL16 will act about the same till ~4000.






I won't copy/paste materials from G.Skill website. You can read about all the features here http://gskill.com/en/product/f4-4266c19d-16gtzr
I will still show a couple of things here but will focus more on the overclocking.

The Trident Z RGB DDR4-4266 kit has only one XMP profile and I highly recommend to buy this memory when you are sure that motherboard can handle it. It's because in some cases, at a lower frequency, motherboards set weird timings and users have problems with stability. Simply if you need memory for AMD Ryzen then take a look at 3200-3600 memory kits or if you have standard Z370 motherboard then also stick to lower kits what will save you some money and problems.
In most cases, it still should work fine but no one will guarantee that.

For main tests, I've picked MSI Z370I Gaming Pro Carbon AC. This little motherboard is in ITX format which has two memory slots and is one of the best for memory overclocking. It's not on the QVL list but it's not an issue.
Here you can see stability at XMP settings which are 4266 19-19-19 1.40V



I guess that over 19h AIDA64 stability test at 95%+ memory load is enough. I was also keeping this memory in my daily rig running 24/7 for about 2 weeks without issues so I'm sure it's stable at these settings.





OC results and benchmarks in post #6 - http://www.overclockers.com/forums/...6C19D-16GTZR?p=8074489&viewfull=1#post8074489

I don't admit to knowing a lot about memory so why does the memory not scale to 2x. If you start at DDR4-2133 @ 9-9-9-18 (the lowest setting that I could get in BIOS) and go to DDR4-4266 @ 18-18-18-36 should the results be 2x. What I mean is " The 2133 memory is running at 2x the speed of the 4266 memory. Should not the 2133 memory score the same as the 4266 memory in read, write, and copy???? Is there something else that keeps the memory from scaling to 2x the transfer per second??

I also bring this up as I'm buying a ASUS X99 (2011-3) and memory prices for DDR4-4000/4266 @ CL 19-20 are $100+ cheaper than DDR4-3000/3200 CL 14. Can I take the DDR4-4000 CL 19 and run it @ DDR4-3000 CL 12/14?? I'm looking at benching the motherboard at a later date. The 2D benches SHOW Massive improvement on what memory speed/settings that you run.
What are the MAX CL settings for benching DDR4-2800, 3000, 3200-3800, 4000, 4200.

The memory used is G.Skill DDR4-3200 14-14-14-34.....

DDR4-2142 9-9-9-18 1T with a i7-6700k OCed to 4692 and FSB to 102.00


DDR4-3535 16-16-16-40 2T (I could not get it stable at a faster speed) with a i7-6700k OCed to 4692 and FSB to 102.00


Thank You For Your Time and Knowledge

As for the first question RAM just doesn't work that way and for the second yes you can run fast memory slower with tight timings.

As a general rule, clock RAM as fast as you can, then start tightening the timings. DDR4 3000 at CAS 12 is fast, but not as fast as DDR4 3600 CAS 16.

I'm not sure why are you buying X99 right now. Better just get X299, even cheap motherboard. Every ASRock motherboard supports DDR4-4000 (I've tested almost all their motherboards).
Anyway X99 will support max 3200-3400 and that depends on many factors. No matter what you buy from TridentZ 3200 CL14, 3600 CL16 or any higher kit which is using 8GB/single rank modules, will be based on Samsung IC and will overclock good on every platform. However, on some platforms max clock will be limited.

I also had no time to perform additional tests and I only made that stability tests in 1st post.
Will try to catch up in next days...

I will finally go back to memory tests as I think you count on something more than a single result at XMP settings

All 3 results are at timings from XMP profile. 4266-4400 requires 1.35V SA / 1.30V IO, 4500 requires 1.40V SA / 1.35V IO.

4266 19-19-19 1.40V

4400 19-19-19 1.40V

4500 19-19-19 1.40V


1.45V, CL18-18-18, sub-timings about the same as in XMP profile:

4500 18-18-18 1.45V

For some reason, I can't stabilize memory at more relaxed timings and I can't even boot at 4600. I will investigate this issue and update this thread with some more results.
Used motherboard and BIOS are capable of DDR4-5000+. Used memory IC is the same as in DDR4-4700+ memory kits.

That's some fast and tight RAM.

Not complaining since it cost me ~$30 more than DDR4-3600. I just wonder what am I missing since it easily runs at DDR4-4400/4500 and it can't even boot at DDR4-4600+. Now testing DDR4-4500 18-18-18.

Edit:
4500 18-18-18 1.45V added to the #6 post.

Great stuff Woomack

4666 20-20-20 1.55V / dual channel , not stable and has problems to pass more demanding tests

Can someone translate this to idiot speak plz. Is 4266mhz worth it in an Asus Apex 8700k
?

Nothing above ~3600 CL16 will be much faster in daily work or games. There are single programs that will use faster memory but again, once frequency goes up then timings have to be more relaxed and we can have situation when with higher memory frequency, performance isn't changing.

Ok, so buying 3200 mhz with tight timings and attempting slight OC is the way to go. Thanks. Saves some money too.

If anyone is interested, 4500 20-20-20 1.40V runs for about 2 weeks without issues. Stable in everything, PC up 24/7. MSI Z370I Gaming Carbon ITX motherboard.
Tighter timings are not stable and higher voltages are not helping. Maybe it's IMC or platform in general but CL20 for DDR4-4500 is still good. The same results on 8600K and 8086K.
Screenshots are around the forums in a couple of threads.

New beta BIOS for MSI. It supposed to add 9th gen CPU support but I guess it includes a couple of improvements from unpublished betas.

Hey guys! Just sneeking in here to get some reviews for my final ram settings-result. (It´s probably bad compared to your frequency´s )
Adjusted all timings i can find with a ton of research ^^


cheers

4266 kit is just a higher binned Samsung so about the same as you have. A lot depends on the motherboard and BIOS. My results in this thread are on one of the best motherboards for memory OC so can't really compare that to most other motherboards.
I bet you can set higher clock like 3600 15-15-15/16-16-16 1.35-1.40V. 4000+ is not guaranteed and usually requires some manual settings. It doesn't change fact that 3200 14-14-14 is already good for everything and I doubt you will need higher clock.

I guess you can find some info in these threads:

Thanks for the "Statement" Woomack Well im kinda struggling to get the clock higher than 3200 without raising the voltage to 1.45... i can also only reach it with 2t. its a 3200 cl16 32gb kit on my asus z370-h gaming mainboard.

Thanks for the review, good to see that high end RAM from 2018 in dual channel can finally pass the bandwidth of quad channel RAM from 2013
