G.SKILL TRIDENTX 8GB 2400C10 Dual Channel RAM Kit Review

Memory by leeghoofd @ 2013-02-04

The G.Skill brand has become one of the more popular ones in the enthusiast community. This Taiwanese RAM company has won the hearts of many overclockers, especially due their binning methods and affordable price tag. Therefore G.Skill manages time after time to launch RAM kits in multiple speed/timing versions, different quantities and best of all they usually sport some overclocking headroom. G.Skill introduced simultaneously a new series of RAM, baptized TridentX, together with Intel's launch of the Ivy Bridge CPU. The RAM vendors had to readjust their binning methods, mainly due to the high ram speed support of Intel's 3rd generation CPU. Enthusiast RAM isn't solely based anymore on just tight timings, high RAM speeds is one of the new requirements. The TridentX kit reviewed today is one of the medium specced kits, comprised of two 4GB dimms running at a whopping 2400MHz RAM speed, however affordably priced at sub 75 euros.

Tweaking the XMP Profile

The XMP is an excellent starting point to commence our tweaking journey. Normally most users just touch the main timings to unleash a bit more performance ( CAS latency, TRAS, TRP and Command Rate ). Some daredevils go deeper and start to fiddle with eg TRFC and other subtimings to max out their system's performance. As being part of the tweaking community we tested a lot and the alteration of the below values gave us the best boost for a daily basis.

We will start our tweaking adventure from the stock XMP profile of our TridentX kit : 2400Mhz 10-12-12-31 Command rate 2T.

We work our way down and change each setting accordingly to what we have deemed to be stable for our sample kit:

Tighten Command Rate from 2T to 1T (biggest boost)
Tighten tRCD from 12 to 11
Tighten tRP from 12 to 11
Tighten tRAS from 31 to 21
Lower TRFC from 150 to 124 ( can be lowered even further )

So we end up with 2400MHz running at C10-11-11-21 1T iso 2400MHz at C10-12-12-31 2T, this without adjusting box rated voltage of 1.65Vdimm.

Even though the tighter timings won't bring that much performance, just keep in mind this is at no extra charge. It just takes some time to adjust and test to see if it all remains stable during daily operations. In SuperPi 32M the close to 3 sec gain is mainly due to forcing the Command rate 1T:

In AIDA64, the bandwith numbers get a small boost, especially the read test achieves a 1000MB/s higher score. The Photoworxx test, highly influenced by bandwith get's a nice boost too. In encoding a 2FPS extra during rendering is a nice gain:
