Following yesterday's ADATA review we will have a look at another 16GB memory kit today. The kit belongs to GeIL's new Evo Veloce series and consits of two 8GB modules running at DDR3-1866 MHz CL10-10-10-32 with 1.5v. Nothing really special on the paper but once we started to play around with this kit we have been surprised. In good or bad? You will find out in the following pages!
Evo Veloce, where
Veloce is the Italian word for “speed”, is how GeIL named their 4th generation top of the line DDR3 Hardcore Gaming Memory.
Below you will find the specifiations of the kit:

Taking a closer look at GeIL's memory
line-up shows that the Evo Veloce fit in their mid-range. This is being
underlined by some 10-10-10-32 timings, which is nothing special. Of
course, doing so at 1.5V is more difficult than at 1.65V, but it’s
hardly an achievement. Given that the majority of DDR3 memory ICs are able to provide a
decent overclocking and voltage headrom for scaling.

Closer Look
The Evo Veloce kit arrives safely boxed in a
transparent plastic blister which is put in a small cardboard box that features a window for a better presentation.
Inside, we find a pair of Evo modules,
which feature an overhauled design. The heatspreaders are now red to indicate that we’re dealing with very
fast memory. Unlike many other makers, GeIL doesn't use custom coloured PCBs,
so on the standard green, Evo's red heatspreaders look kind of attractive. I
don't think that a black PCB nor a red one would have make them more "cute".
Removing the heatspreaders is quite easy.
Once you've heated modules up, for example with a hairdryer, they almost fall
off.
Today we expected to see either Hynix or Samsung ICs on these 8GB modules. But
what we've come across was quite a surprise, since GeIL went for Micron chips instead. Even if the
chips are relabeled there are a few hints that help to find the maker. Timings
fomula, rated voltage, dot on the IC, IC's size and the number at the top left
of the IC tell us that they come from Micron. Micron doesn't have that a lot
of different
4Gb chips so my guess goes for the D9PBC.
Each module is flashed with an SPD that provides basic
information on the manufacturer, capacity and the production week. The serial
number is not so important so we don't really care if not present but it's a
pity that the part number is not. Instead of a part number you find "CL10-10-10
D3-1866".
SPD is
also responsible for setting the memory up out of the box, for which it features
three JEDEC profiles and a single XMP. The XMP is well recognized by both BIOS
and CPU-Z.

Testing Method & Test Setup
It's the first time we are dealing with Micron's D9PBC chips
so we armed ourselves with an Ivy Bridge testing platform that
should allow our memory to show every last bit of its overclocking
potential.
To make sure that our figures represent the sort of stability safe to use
ever day, we are going to run each setting until we get a 150% pass of eight
750MB instances of HCI Memtest that is considered one of the toughest memory
stress-tests around.

Results
But immediately, we encountered a couple of issues.
First, we found out that GeIL’s SPD sets the subtimings too tight, making
high frequencies unreachable without manual adjustments. On the
screenshot below we demonstrate which values we had to loosen when testing the
overclocking capabilities of our kit.
Another
thing, we’ve noticed is that unlike all recent Micron 2Gb D9 chips we tested previously, our
Evo Veloce
fells flat on their face using identical primary timings. Raising tRCD by one value
above tCL and tRP has noticeably improved the situation.
As you can see from the results chart, past 1.5
Volt scaling comes to an end. More juice only
increases the power consumption. Usually Micron ICs are able to digest higher voltages.
It would
be interesting to test a memory kit made by Crucial to see if the problem really is
related to the IC itself, the SPD or the PCB. We reckon - with our
past experiences - that limited voltage scaling is caused by an imperfect PCB design.
At the moment this kit looks very bad but in fact it isn't. Check
out the results, the kit can achieve much higher frequency than the specs at
only 1.35v. At 1.5v it is even stable at 1'020 MHz with the rated timings which
is 87 MHz more than the frequency the kit has been specified for.
But in order to obtain the best of the kit you will have to raise timings a bit
to 11-12-11-34 and set the voltage to 1.65v. In this case the kit will fly,
1'200 MHz was almost reached 400 % stable.
If you are scared to use 1.65v on a 1.5v rated memory kit then you can keep 1.5v
and lower the timings to 9-10-9-28. In this scenario we were able to run the Evo
Veloce at 980 MHz.

Conclusion
Using geizhals as our price research tool, we find that offers for 2x8GB sets of
1866C10 Evo Veloce start at 90 Euros excluding shipping across the EU. Taking a look at similarly clocked kits from other manufacturers shows us that the
G.Skill Ares are the cheapest for 67 Euros. Price goes up to 150 Euros with
Corsair's Dominator Platinum. From 30 different memory kits the GeIL Evo Veloce
are right in the middle price wise.
Being an overclockaholic website, overclockability is
one important feature. Sadly, this kit left us with mixed feelings. On one hand
the kit can do way better than the specs which is very good. On the other hand
it's not easy to work with and the scaling stops at 1.5v for most timings.
Pro:
Design fits perfect red/black motherboards
IC quality is way better than the specs
Con:
High heatspreaders
You have to play with secondary/tertiary timings in order to stabilize the kit
Voltage scaling stops at 1.5v
Rating
The
GeIL Evo Veloce GEV316GB1866C10DC kit receives the rating of
4 out of five stars.
