My last test was based on higher clocks so today something lower clocked but based on 8GB modules - G.Skill TridentX 1866 8-9-9 1.60V.

All know how TridentX look like but here is one photo:

TridentX is probably the only memory series on the market where we still can expect Samsung memory. Also 16GB kit tested today is based on higher density Samsung IC. I didn't check what exactly is inside but looking at SPD profile and some other things it looks like HCH9.

No matter what we see under the heatsink, let's focus on test results as it's most important.

As all G.Skill memory also here we can find two nearly the same XMP profiles. Little differences can be helpful if one of the profiles for some reason won't be stable and then we can use second one. So far I haven't had any issues with any of G.Skill profiles but of course no one can guarantee compatibility with every available motherboard on the market.

Below we can see performance at stock settings XMP #1. Since both profiles give about the same performance then I won't add second screenshot.

2600+ couldn't pass HyperPi 32M. It's booting without issues but I couldn't stabilize it.
All other tests in this thread also passed memtest86+ 5 RC1.

8GB modules are generally harder to overclock but in this case we see pretty good results in both, high clock and tight timings. Also performance is really good.


If you wish to see some other tests based on this memory then please let me know in this thread and I will try to add something more.

Great review Woomack.

And thanks to you, my 16GB Trident X finally run@2133/Cl8!
 
Correct me if I´m wrong but 2133 8-10-10-24, CR1, tRFC 178, 1.68V seems to be the sweet spot, right?
 
2133 8-10-10, 2400 9-11-11 and 2400 10-11-11 are performing about the same or at least you won't see difference. Actually best results in HyperPi were on the worst setting of these 3 so 2400 10-11-11. 2133 CL8 on 16GB kit looks pretty nice :)
I see you have the same memory. Just compare performance in AIDA64 ( most important is read ) and HyperPi 32m. On your motherboard with different sub timings results can be slightly different. Sub timings are in AIDA64 window so you can check if they work for your memory. I see they're not so tight so you can play some more if you want.
Overclocking results may vary depends from kit. All of them are on similar Samsung chips but some are overclocking better than the others.
