Besides the great looks it's time to find out if these sticks perform likewise. Take note that the 2666Mhz speeds are set via the XMP profile. The 2400C10 and 2800C11 timing and subtimings are based on the values set by that XMP profile. What better test to start off with then SuperPi 32M. ? A bandwith hungry test that adores tight timings, mucho bandwith and low latency. A 1600C9 kit, is what is currently considered as mainstream value ram. The TridentX kits gain over 15 seconds, quite a feast for a bencher. As usual, the RAM timings ofcourse play a part. But if you can reach higher clock speeds with slightly looser timings you won't loose much performance. This is exactly what we are seeing with the comparison between the 2400C10 and 2666Mhz speeds.
Wprime is not that RAM dependant, why include it them you might ask ? Just to show you that not all software reaches higher performance with fast RAM. A tiny gain in time over the 1600Mhz speeds. The Y-cruncher showed our first anomaly in our test suite. Why on earth would 2666Mhz be beaten by lower specced RAM ? Maybe AIDA64 can shed a light on what happens.
Observing a slight increase in bandwith from 2400Mhz on. Yet the gains are far from the big leap forward when coming from 1600Mhz. The COPY result for the 2400Mhz speed is not a fluke. Time after time +/-28000MB/s was displayed on the screen. Since we only set the main timings manually for the 2400 and 2800Mhz speeds some setting must drastically influence COPY bandwith. We saw a similar outcome with the Photoworxx test. 2400mhz rules the board here. Does the Gene V set far looser timings to support high RAM overclocking ? We will go a bit deeper on the next page.
RAW CPU performance hardly get's influenced by faster RAMs, Cinebench Release 10 multithreaded output is within the margin of error, however the single threaded test seems to get a small boost. Cinebench Release 11 scales in the OpenGL test, the CPU test is from 2400Mhz RAM speeds almost status quo.
Most of these synthetic tests show performance scaling with increased RAM clocks. Rendering via our X264HD test get's a big boost in the Pass 1. Nine frames per second gain is quite impressive in my book. Let's head on to 3D. Do games scale with high RAM clocks ?
Since Ivy Bridge is already a bandwith monsta, the aging 3DMark01 tests hardly sees any influence from stock 1600 speeds to the jawbreaking 2800Mhz setup. Similar outcome with 3DMark06, very light scaling with massive increased RAM clocks.
And last but not least, in fact it has been proven time after time, games hardly get a performance boost with fast RAM:
