Features

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.

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 4 x 4GB 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.

G. Skill's 2400 MHz 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 2400 MHz 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

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 eggsFastest Affordable Memory

Pros: System Specs:
Intel i7 4790K 4.8 GHz
ASrock z97 OC Formula
2x8 GB G Skill DDR3 2666 MHz
SLI Asus GTX Titan
Cooler Master RPP 1250 watt

This set of memory is very impressive. The fastest set of memory with the capacity I wanted without being outrageously expensive. I have been using G Skill memory exclusively for about 4 years now. Back when I got my first set, G Skill was still a new company, untested in my eyes, but with specs, prices and a warranty that told me they were the future of high performance RAM. I've owned a number of G Skill sets through that period and none of them ever failed to meet my expectations and even exceeded them on occassion.
This set of G Skill memory is also backed by a lifetime warranty. Which is a huge selling point for me. I usually only buy from manufacturers that offer lifetime warranties with their products. The fact that a company is willing to offer a lifetime warranty tells you something about the quality of their product. G Skill also has excellent customer service and tech support.
I wanted the fastest memory I could get without breaking the bank. I entertained the idea of trying a different brand, but nothing in this category could match G Skills performance to price ratio. With a choice between two similar sets, I chose to pay a little more for the set with the lower cas latency. The way I see it, both sets are pretty much the same with the difference being these sets are the cherry sticks. The sticks that exceeded performance standards. If only you could pay an extra $30 and get a CPU like that. I also based my choice on some reviews I read stating that these sets are particularly good for over clocking. I usually don't OC my RAM, but I wanted to be sure they would run at the rated frequencies and timings and I may choose to OC them some day.
Anyway, I really like this set. I've read a lot of reviews complaining about the cooling fan, but I find it to be appropriately designed. I've been wanting a RAM cooler for some time now, I haven't had one since the days of DDR2. Yes you may have to bend it a bit, but that's the way it's designed. So it has the ability to fit in any number of situations. Does it keep the RAM cool? I don't know. The RAM runs cool with it or without it. But if you choose to over clock or increase voltage with this set. I think you will find it useful.
I had no trouble getting this memory to run at rated specs. I just enabled XMP memory profile 1 and it set up the timings and the clock speed automatically. However, I entered them manually just to be safe.
I stress tested it to ensure stability and it handled it fine. Didn't even break a sweat.
I was actually able to set the command rate to 1T. I read on a number of reviews that most G Skill sets can handle a 1T timing. I was also able to OC it to 2750 MHz, but that's not the limit of this sets capability. I didn't try to exceed that speed.

Cons: The LEDs on the cooling fan are too bright. My old system had a bunch of cold cathodes and other LEDs to give it some flair. But with this rig in my bedroom, I wanted it to be as dark as possible and these LEDs are as bright as they come. With nothing but my monitor and the cooling fan LEDs, it's enough to light up my room to where it's fairly bright. Too bright unfortunately.
Also, I think the memory cooler is bit too tall. I think it would perform better and fit more snugly if it were a bit shorter.
1.65 volts. I would like to see memory at this speed running lower voltage. It's not really much of a con, since it's to be expected. It's just something I hope to see in the future.

Other Thoughts: Using AIDA 64 this memory achieved a read bandwidth of 39.9 GB/sec and a write bandwidth of 41.9 GB/sec on my z97 at 2666 MHz 11-13-13-35 1T.
For 8 GB sticks this memory is pretty impressive. Usually the higher capacity sticks have higher latencies than the 4 GB or 2 GB sticks.
G Skill Trident series is among the best PC memory you will find. These sets have a detachable top cooling fin, for systems with limited space or to fit under low profile CPU heatsinks.
This set came in a nice package. Very tidy and safely packed with a nice little sticker. It's a very visually appealing memory. It has a very aggressive look to it. I just wish I could get some yellow cooling fins to match the overall color scheme of my PC.
I've read several reviews where users were able to achieve close to 3 GHz with this set of memory. If you were to buy a set at that speed you'd be spending $600 right about now. Better to buy this set and attempt to over clock it.
Having extreme memory speed doesn't really improve your frame rates by much in most games. But there are a few games where memory speed makes a significant difference. Especially with DX11 games. We're getting to a point where next gen graphics engines will be able to take far greater advantage of extreme speeds in memory and multi core CPUs. I only ever use the best components when I build a PC, but within reason. I could have got 3400 MHz memory, but the price is ludicrous. For the best performance, but with a reasonable price tag. This is best set of memory money can buy at this time for dual channel.
I haven't found any reason to deduct any eggs off of this sets score. So I'm giving it a 5 egg rating. Eggcellent memory!

UPDATE: I updated my review because my memory bandwidth wasn't reading correctly on AIDA 64. The true bandwidth was 39.9 GB/sec read speeds. Much better than what 29.9, which is what I posted previously.

5 out of 5 eggsFantastic RAM Kit, G.Skill Continues To Impress...

Pros: - O/Cs Great. Currently running the kit at 2933MHZ @ 12-14-14-35 2T @ 1.66v on an Asus Rampage VI Extreme.

- Massive cooling improvement with empty slots between the sticks. A 4x4GB configuration simply BAKES the inner sticks in a heavily O/Ced system under max load even with fan cooling.

- Was able to remove top portion of heatsink (red part) so that the kit fit perfectly underneath a Noctua NH-D14. No fan needed in open testbench to cool the kit thanks to the empty slots in between.

- Exceptional timings for 8GB Dimms.

- X.M.P. 3.0 - highly compatible & 'idiot-proof'

Cons: - None

4 out of 5 eggsSolid RAM

Pros: Very Fast Cards. Solid construction, good reputation. Noticeable difference when running VM's between 1333 and 2666 speeds.

Cons: Included RAM cooler seized up after 1 month of operation and began a bearing growl after only one week. No way to refund it, not sure I want to either. Seemed pointless, they never get hot without it anyways.

Manufacturer Response:

.
Dear Customer

Thank you for your G.Skill purchase and review. Glad to hear the memory is working fast in your system and you notice a significant difference. DDR3-2666 is double the bandwidth and throughput of standard DDR3-1333 RAM, so it is a huge improvement if the speed can be put to use. With a basic CPU overclock, processing power is greatly enhanced. With regards to the RAM cooler, if it is not working properly, contact the RMA dept for assistance. You are correct in that the Trident X heat spreaders are very heavy duty so they will keep the memory nice and cool even without the fan. For any further questions or concerns, please feel free to let us know.

Thank you
