G.SKILL Trident X Series Gaming Memory Modules
Overview
It's Not the Fastest Until It's TridentX!
Memory Frequency World Record at DDR3 4404MHz
Breaking the highest DDR3 speed world record at a staggering 4404MHz in 2013, G.SKILL TridentX series is known as the world's most powerful and fastest DDR3 memory available on the market. Named after the powerful weapon of Poseidon, Greek God of the Seas, G.SKILL TridentX is imbued with extreme overclocking capabilities waiting to be unleashed in your system.
Removable Heat Spreader Fin
The G.SKILL TridentX series features a removable heat spreader fin to improve your cooling options. With the heat spreader fin, the increased surface area keeps the memory cooler. Alternatively, with a system that already has a sufficient cooling solution, the fins can be removed to accommodate massive CPU coolers or other customized cooling solutions.

G.SKILL TridentX heat-spreader comes with removable top fin design. It allows overclocking enthusiasts to have more flexible options of memory cooling systems, as well as to reduce the height to fit with large CPU coolers.
 
Extreme Performance
Extreme overclockers and PC enthusiasts look no further, G.SKILL's TridentX DDR3 memory will push your system to an unimaginable limit. Not only available at ultra high frequencies of 2400MHz, 2600MHz, 2666MHz, 2800MHz and 3000MHz, but also available with extremely low timings at 2133MHz CL9, 1866MHz CL8, and 1600MHz CL7!
Intel XMP Support
All G.SKILL DDR3 memory comes with the latest Intel XMP standard developed for Intel platform. It provides PC enthusiasts an entirely trouble free overclocking experience to boost their 4th Gen Intel® Core™ processors with Intel 8 series systems for extreme levels of performance, while retaining system stability.

Lifetime Warranty
All G.SKILL memory products come with a lifetime warranty and the G.SKILL technical team is always ready to provide consumers with complete technical support via online forums, telephone, and email.

"If you follow my posts on the forums, you'll find that I consider myself one of Corsair's biggest fans, but those feelings were thrown completely out of whack when I received this kit from G.Skill. The G.Skill F3-2666C11Q-16GTXD kit managed to completely amaze me with its quality and clocking ability, and I fell in love after checking its price. You cannot find a 4x4GB 2666MHz kit for less right now unless it's been put on sale. This kit manages to overcome any performance deficiencies with flexibility and great overhead. At stock, I managed to beat out my trusty Corsair Dominator Platinum kit with a little bit of tweaking. Overclocked, the G.Skill F3-2666C11Q-16GTXD kit managed to go just as high without a boost in voltage. That is just outright fantastic."
 
Editor's Choice at Neoseeker
G. Skill's 2400MHz Trident X kit put on an impressive display of performance, easily overcoming the competition in all but four of the benchmarks used. Unfortunately the memory was bottlenecked by the processor, limiting the overclock to a 104 bclk and leaving us with a final overclock of 2218MHz and timings of 10-12-12-31 2T. Paired with a 3rd generation Intel processor, G. Skill's 2400MHz Trident X kit would have benefited greatly from the increased bandwidth and has the potential to hit 2500MHz with some fine tuning.
 
Gold Award at OverClockersClub
G.Skill's Trident X line-up comes with kits that range from the 2400MHz kit we are looking at to a 2800MHz kit for massive memory speeds and the associated bandwidth that is a hallmark of higher speed bins. It seems that G.Skill is most definitely targeting the budget overclocker with this set of Trident X modules. A $99 price tag for 2400MHz-rated modules is a welcome sight after seeing huge price tags just a few months back for cas8 and 9 modules binned above 2133MHz. The Trident X are modules that perform well and deliver some overhead for a little bit more tweaking and come with G.Skill's lifetime warranty. Excellent looks aside, the Trident X would make a good addition to any system and have the flexibility to be cooled in multiple ways.

5 out of 5 eggsFast!

Pros: This memory is amazingly fast. I have it equipped with my Asus ROG Maximus V Extreme and the i7-3770k and I couldn't be happier. Running at 2666 I'm able to run BF3, photoshop, steam, a browser, and all of my security features without a hitch. My computer seamlessly runs between the programs. Truly amazing memory.

Cons: None whatsoever.

Other Thoughts: If you have a Z77 motherboard and an i7 processor, GET THESE! Absolutely worth it.

4 out of 5 eggsweird

Pros: haven't tried the ram

Cons: I just think its weird that you dont save any money buying the 4 x 4gb ram over two of the 2x 4gb. In fact you would save $0.01 lol and get a second memory fan to give to a friend if you went with the latter lol. Idk whatever i guess. (i'm sure this will not apply in the future)

Dear Customer

Thank you for your G.Skill review. This is an extreme memory kit that will produce outstanding results. If you are looking for top-of-the-line memory for your Z77 platform, this is surely a kit to get. Currently, only the Intel i7-3770K CPU is fully capable of these specifications. For all other CPUs, the memory will be compatible, but the maximum achievable frequency will depend on the specific CPU.

With regards to pricing, more modules in a kit should actually cost more than one with lesser modules. Reason being, each kit is fully matched and guaranteed to work in a single system. If you purchase the 2 x 4GB kit, only 8GB is guaranteed in your system. If you use two kits, you may not be able to reach the rated specifications of the memory. Especially with high frequency memory, it is difficult for multiple modules to match, thus the reason for a higher cost. For multi-channel motherboards, perfectly matching modules is critical for a stable system. Should you have any further questions or issues, please feel free to contact us directly.

Thank you

4 out of 5 eggsUpdate 3rd and final adendum to previous review.

Pros: Ok, here is the final scoop. I returned the original i5 3570K processor of which this RAM would not run at any speed above 2400 regardless of any adjustments and or tweaks attempted.

Since then using the same Board Asus Maximus V Z77 with two i7 3770K and the Trident X RAM. RAM ran flawlessly on both i7s. I then installed two dif i5 3570K processors. In line with some opinions I had discussed with some fellow high ranking overclockers, the theory concerning the i5 3570K seems to be correct. He had stated that the units from Cost Rica did not like high RAM speeds above 2400. My original chip which would not handle above 2400 was indeed manufactured in Costa Rica. The other two i5s which did work fine at 2666 ironically were manufactured in Malaysia.

So if you plan on using this RAM on a i5 3570k make sure its from a manufacturing run in Malaysia. It may not be a guarantee however I am two for two with the Malaysia chips. Your experiences may differ.

Cons: Product support in my case was lacking, which is a surprise as G Skill touts themselves as being very customer oriented and most clients purchasing such RAM are usually pretty savvy and knowledgeable to start with

Other Thoughts: Hope this helps anyone who might have run into the issues of which I had with the Trident X's not working, as well as keep you from having to go through a lot of trial and error troubleshooting. Most people aren't usually afforded the ability to have access or purchase numerous chips in order to find one which will handle such speedsThe manufacturer in my case did not seem to know about these issues and did not offer much in the way of support when contacted. Also if they are aware (which if they know their product, they should know such issues. Would have come up in testing and certification)one would think. It is in fact their duty to be familiar with their own product, as such should have been able to give generally the same info and supply a fix when approached with such a problem,.

Dear Customer

Thank you for your G.Skill purchase and review. Glad to hear you were able to get this memory kit working properly. For all G.Skill Trident X series memory, an Intel i7-3770K or better CPU is highly recommended. With extreme memory, not all CPUs will be capable, so it is up to the user to test and determine whether the CPU can. Your provided information is appreciated, it should help others determine whether the chip they have may be competent. For any further questions or issues, please feel free to contact us directly.

Thank you

3 out of 5 eggsUpdate to my review above using this RAM and i5 3570K Possessor

Pros: Works flawlessly with the i7 3770K; however (see below)

Cons: RAM is not likely to run at rated speeds on any of the lower numbered processors. In my case, even with numerous tweaks and adjustments, this RAM would not and did not run at rated speeds nor at anything above 2400. Have talked to numerous fellow overclockers and the consensus is the i5 3570K processors generally dont like speeds above 2400. The IMC's tend to not be able to handle the higher speeds. One tester ran tests on about 15 retail i5 3570K processors, out of the aprox. 15 only 4 or 6 of them (in that range) would even post at the rated speeds of this RAM. All the rest he emphasized no matter how much tweaking, and no matter his extensive expertise, the other 10 or so would not run period on rated speeds and/or above 2400.

Other Thoughts: In response to G Skill above.....

Instead of inferring the customer (me) must not be knowledgeable in overclocking. (do you know me? have you met me? Do you know my skill level and knowledge?) NO!

so...

Instead of taking cheap shots and insulting customers, is it possible that you might make your customers aware that this RAM is only best suited for the i7 3770K processors?

Its also common knowledge what code 23 means and it has to do with the IMC and the fact that it does not want to run at the higher speeds (above 2400 on the i5 3570K CPU in my case)

I am guessing that profits might have something to do with the lack of disclosure on the part of G Skill. Or am I just unknowledgeable? Well if so then why do I know this info and the fact that code 23 means what it does yet there was no mention of either or any of this info in G Skills response. So instead of insulting your customers G Skill with all due respect, you might want to spend more time offering actual technic

2 out of 5 eggs

Pros: Solid heat sinks, Solid feeling RAM, promising conceptually

Cons: RAM will not run above 2400 on Asus Maximus V Z77 Motherboard, and i5 3570K Possessor. No matter what settings, voltage adjustments, etc. Cannot get RAM to run on either of the 2 XMP settings. Board will not post and will give error code 23. GSkill Support has only said to try raising VCCSA voltage to no avail. Disappointed in the lack of support from G Skill as their answer to my very specific email was a very brief less than one sentence answer. Did not even specify what voltage to try. No one wants that after waiting 24 or more hours for a reply to an expensive problem. Only to have to ask same over again and wait all over again. It's a volleyball game and so many companies just want to put the ball back in your court ASAP without actually doing anything.

Other Thoughts: I guess Friday afternoons aren't a good time to obtain more individualized support. I have to say after many new computer builds over the last year and a half, (More than 8 full builds) I am getting tired of Manufacturers using the customer and RMA's as a form of quality control rather than in house QC. Have seen it on many Asus Motherboards, and other computer peripherals/components. I also have to say shame on NewEgg for sending me a defective Rampage Extreme Motherboard then denying replacement blaming the customer (me) for bent pins of which is a blatant falsity. Feel compelled to mention this as if you read some of the more recent reviews many other NewEgg customers ironically have stated the same treatment and denial of exchange or replacement by NewEgg, blaming the customer for damg this case it was an almost $500 motherboard. None of this stuff is cheap yet the customer is the one who pays the price for poor quality control which seems to be rampant across the board these days

Dear Customer

We are sorry to hear you had issues setting up the memory. This is an extreme performance memory kit, so overclocking experience is necessary to configure the memory and supply the proper voltage. First, please follow the attached guide below to enable the XMP Profile and input the basic DRAM memory values. In addition to these basic settings, the VCCSA and memory controller voltage should be raised to stabilize DDR3-2666. Keep in mind that Intel CPUs only support DDR3-1600 CL11 max, so with any memory kit better than that, additional tweaks may be necessary to stabilize the CPU/system. For any further questions or issues, please don't hesitate to contact the G.Skill technical support team. If you have time, feel free to join the Official G.Skill Forum. There are many users with similar combination that can help, and an overclocking section that you should find useful.

Thank you

5 out of 5 eggsWorks 1st time in XMP!!

Pros: Fast! My setup is an ASUS P8Z77-V-Deuxe MB, i7-3770K @ 4.6GHz(P95 stable), Corsair H100 cooler, a CoolerMaster 1200W PS and two GTX 680's in SLI. Except for one experience(see below), G.Skill memory has always worked per spec the first time!

Cons: Cost, No stable OC @ 2800 and above yet

Other Thoughts: I had originally bought the 2600 version of this memory and could not get a stable XMP OC above 1921 MHz. I talked to Tim(very helpful) at G.SKill and tried everything he suggested(i.e. Vccsa should be @ 1.25v), but still no luck. RMA'd the part back to NewEgg for a refund and decided to buy the 2666MHz set. 2nd time was a charm, and NewEgg really treated me very well during the whole process!!
