“... Essentially what
the UD4H is, is a
refreshed UD3H.”
All results were obtained at 4800MHz s on an un-optimized Windows7 64-bit and Windows XP SP3. These are our
results, yours may vary so only use these as a guideline for a similarly configured system.

We tried the notoriously hard
to overclock AVEXIR Core
series 2800 memory on the
board. It worked first time
around at 2,800MHz with all
four sticks. Do not be fooled
into thinking that is an easy
feat as it’s not. Not every CPU
has a 2800MHz IMC and not
every board can operate the
memory at that speed with
two sticks let alone four. The
UD4H didn’t’ skip a beat and
it was a simple matter of
loading the XMP profile and
rebooting the system.
With other sets of memory,
the UD4H proved to be just
as capable as any of the
dedicated overclocking
boards on the market. One
such example was when we
compared the UD4H against
the ASRock Z77 OC-Formula.
The UD4H was not only
capable of matching it in
frequency, but as you can see
from the results, matched
it in performance as well,
coming out ahead ever so
slightly in some benchmarks.
So for the overclockers
out there looking for an
even more cost effective
board, this is the one to get.
If you consider memory
overclocking capabilities and
the efficiency of this board,
you’ll find that it offers
even better value than the
UD3H, perhaps even the OCFormula in some instances.
In the end the only negative
aspect of this board is that
it may have come a little too
late in the life cycle of the
Z77 chipset, but other than
that it’s a solid board that
could in fact be the gem of
the entire Z77 series from
GIGABYTE. We aren’t sure if
there’ll be any kind of “Rap”
competition concerning
this board as we saw with
the UD3H, but if ever there
was a board to deserve it, it
would be this one. The Z77XUD4H has become an instant
favourite of ours.

Summary
The Z77X-UD4H isn’t
much different from
what the UD3H offered.
In fact it’s damn near
identical, which is good.
What makes it worth
the extra spend is the
vastly improved memory
overclocking, which in
our books makes an
already efficient board
even better.
Would you buy it?
Most definitely, it’s the
UD3H improved.
