User short review – G.Skill TridentZ 3600C17 2x8GB B-die retail on test

Postby websmile » Sat 12. Mar 2016, 18:15

Hi and welcome to my mini review on a random 2x8GB G.Skill TridentZ DDR4-3600 C17-18-18-38 1,35v kit. This fast test is meant to give an impression on the relatively new Samsung B-die IC, introduced on retail kits end of year 2015, which now already dominates the benchmark and oc scene. The sample tested is retail as well, for people who know me they will also know I was a quite active memory tester and binner in the past, so end of 2015 I contemplated about what to do after the new B-die kits were released and decided to test a couple of kits.
This is when the problems started :D – before I carry on with test system and results there are two issues I have to address because for users going for new kits to bench with, these might be important.
First, you will see tons of results showing 2K Cas12+ by Pro and elite ocers, voltage given 1,8v or a bit higher. Don´t expect this to happen to you when you buy a random kit, chances on retails are low to achieve even 3866 or 4000 12-12-12-28 tight at CR1, most results you will see are by handpicked special samples given by vendors to ocers as support and promo. If you know the oc scene, you will remember that this already started at late DDR3 times, if you didn´t knew, now you do. You can judge this the way you like to do, I state this here to show relations, so if you buy a retail kit that gives you a solid 3866 Cas 12 tight below 1,9v, you are not unluckiest guy in the world but can be happy the kit is solid.
Second, and much more important for me personally, is the issue that brought me the kit together with two others that I tested today. I bought around 20 kits, all G.Skill ripjaw5 and TridentZ, since December, not because I have too much cash or because I am even more crazy than I am for real, but because I constantly needed replacement. Out of the 20 kits I got brand new from german online shops, I had three DOAs and four kits that failed specs out of the box. You will easily determine a DOA because the sticks simply don´t boot, but I can only advise you to test each kit you get sealed for specs with memtest first. I cannot determine if it is the IC itself or sloppy control, but it is an annoying fact which was also confirmed by a lot of other binners and ocers who faced similar problems. To be fair, this also hit other vendors on B-die, but I see no reason to stay quiet about this when it might help people and avoid problems for them by simply telling them the way it is and recommend additional testing.

After I now became popular with some vendors, let´s simply show what my kit could do :D – if you wonder about the cpu used, it has a better imc than my very strong 6600K, who is good on core oc but at best average on imc, and I saw no reason to risk its life by putting on insane io and sa voltages like I did on the Pentium^^

Test system
Intel Pentium G4400
Asus Maximus 8 Impact Bios 0014
G.Skill TridentZ DDR4-3600 C17-18-18-38 1,35v
Dell 7800GTX
Mushkin AP800 PSU
OS Windows7 X64 Ultimate at Maxmem set 4000MB

After checking specs with memtest I decided to start the tests at settings relevant for benchmarks and skip the usual review pattern, so I started at 3600 C12-12-12-28 1T 220TRFC and worked my way upwards, each divider had to pass XTU, superPi32m, Geekbench and several other benchmarks that stress the Ram to see if it is useful for benching, if you want 24/7 settings, you are wrong at this thread^^The Impact undervolts a bit, so shown voltage is 0,01v above real volts

The test and my results

DDR4-3600 Cas12-12-12-28 1t 1,68v

Next divider worked as well, I needed 1,765v for 3733 Cas 12-12-12-28
Image

Moving up to 3866, things became harder, the IMC started to show first signs of weakness, I managed to run DDR4-3866 12-12-12-28 1T at 1,84v
Image


Next stop was DDR4-4000, now things started to get really difficult, but not the mems but for my IMC – I needed 1,35v sa to boot cas12 at 1T, it also killed scaling a bit, which is one of the reasons I already needed 1,96v for DDR4-4000 Cas 12-11-11-28 1T 240 Spi32m, XTU should have worked at a bit less volts

Time for a short conclusion. The tested kit is clearly above average on B-die kits, it worked flawless at specs and gave me excellent results, especially when I take in that 3600C17 is no tight highend bin. If you wonder why I set maxmem for my benchmark tests, this is a platform problem that occurs at all B-die based kits, at tight timings and high voltage at 3600 and above, they lose stability at x64 OS. This is neither vendor specific nor is it a reason to complain, benchers like us use hardware outside of its specifications, so we have to find workarounds if this causes issues. B-die is the way to go for benchmarks at the moment, it is the dominant IC at the moment, and especially if vendors find a solution to improve the ratio of DOAs and kits failing specs, there will be no serious alternative to these as they offer performance and timings no other ic can do even on cold. I hope you liked my short review, feedback is welcome, I hope I can answer these before modul houses delid me^^

Best regards

Very nice and honest mini-review bro ,I like it :D

P.S. best advice..
You will easily determine a DOA because the sticks simply don´t boot
:lol:

Thanks, after that many dead kits I thought a bit of humour is what is needed :P :D

Thanks Marc, the test was fun and I hope some points I adressed are helpful when benchers have to decide which memory and ics are a good choice when you search for extra points benching at the limit

mint work as always Michael :) thanks for share!
my personal feeling about B die is a bit worse... nice mems if you wants to run 32M and XTU but not any good for bclk overclocking...

I like when people make honest reviews, which is very rare these days, in my case even more so, because next week come to my house this new kit Cas 3600 16 Trident-z.
Then I will consult with you the performance of this kit, so I wish to be lucky with this new kit, one and only that Iam going to have, as it took one month from the purchase and arrival in Buenos Aires from USA - Amazon :o
In the south of the world

How many kits did you tested before this 4000 CL12? I tested 4 kits of 3600C16 and best did 3866CL13...

I have now tested 23 kits, plus 3 DOAs I had. If you take superpi 32m as standard, eight could do this, but 3600c16 three out of eight was the ratio. out of these eight, two did 12-11, other 12-12, and it is not as unusual as people think if 3866c12-12 doesn´t work, if you get a bad batch you will opt out at 3733 or maybe even lower

@Alex Let´s hope you are lucky, simply contact me if I can help :)
