When we finished off our Ti4600-8X review, we had said that we were done with
the AGP8X capable family of GeForce4 cards. In fact, at the time we had only
looked at AGP8X versions of the 440MX, Ti4200, and Ti4600 cards, with no intention
to go any further. Thank goodness Gainward sent us their Ultra/750-8X XP card,
or else we would never have bothered to look at a Ti4800SE card, which would
be a shame - because it turns out that the Gainward Ultra/750-8X card offers
a more than decent balance of performance and price.
Nvidia Name Game
As I had explained in our MSI GF4 Ti4600-VT2D8X review, Nvidia has named their
AGP8X capable Ti4400 chip as the Ti4800SE. This can be confusing because the
Ti4800 (without the trailing SE) is the European name of the Ti4600-8X card.
The below chart will give you an idea of the clock speed differences between
the new generation of GF4 Ti cards:
| |
GF4 Ti4200-8X |
GF4 Ti4400-8X |
GF4 Ti4600-8X |
| Core clock |
250Mhz |
275Mhz |
300Mhz |
| Memory Clock |
500Mhz (250Mhz DDR) |
550Mhz (275Mhz DDR) |
650Mhz (325Mhz DDR) |
Note however, that Gainward overclocks their card right out of the box, not
unlike what Abit's been doing with their Ti4200 card. Gainward's card default
is 275/550 just like a regular Ti4800SE, but their drivers will set the card
to 288/615Mhz.
Gainward's Ti4800SE card:
The Gainward Ultra 750-8X card's appearance is somewhere in-between a barebones
look-alike and a more customized card. Gainward uses what they call a "unique"
red cooling fan, but the design is very similar to AOpen's GPU cooling fans,
and we have seen its like before on other cards. While the fan doesn't appear
overly impressive, we have found that it does as well a job as more elaborate
coolers when it comes to overclocking, so don't let its banal looks fool you.

More interestingly, Gainward includes quaint red coloured RAM coolers on all
of the memory chips - yes even those on the back of the card. Whether RAM heatsinks
actually have any positive effect on overclocking success is still in debate
amongst reviewers and enthusiasts, with both sides of the argument having obtained
data to support their claims. We ourselves find that RAM coolers can make a
difference, and if a company includes coolers on all their memory chips, it
saves you the trouble of having to do it yourself later. At the very least you
get a certain peace of mind.
Underneath the memory coolers are either Hynix 3.5ns or Samsung 3.3ns memory.
You might want to take off your RAM coolers to see which, since other cards
that use Samsung 3.3ns sometimes have better overclocking headroom.
