Fast card for it's time

review by kinkinkijkin

Slightly late of a review, but I only got this a year ago

As many people are aware of, the 5770 is still a fast card, if aged. This model is no exception. Unfortunately, though, this model is worse than the reference design in most ways, hence removal of score.

As I said in the pros, the core responds well to overclocking. As in very well. At default voltage, you can get up to 950 core without increased temps. But most already know this.

Now, to something that's unique to this model. Touching the mem clock will cause tons of instability. I tried many different mem clocks, and the only one I could use was stock. I couldn't even reduce it to reduce stress on the RAM modules on the back, because THAT was also unstable, on every setting I used but PowerPlay's default 300 and 600. Both of which are far too low to use for gaming, especially when compared to the default mem clock of 1200.

Of course, 4800 effective memory clock is massive, and I only need more than 2400 half of the time, but I would still like to push it to 5000, and I'm sort of disappointed in this card.

Also, this exact model only has one crossfire connector, and the fan's noise is multiplied by how many months you've owned the card, and unless you're fond of taking your GPU cooler apart and cleaning it every few months, I wouldn't recommend buying a card of this model. Oh, but I hope nobody's thinking about buying a 5770 today. Really, they're four years old at the time of this review.

ProsCons
5770, 1GB RAM, DX11, good temps, core responds well to OCMemory virtually un-overclockable
