MSI GeForce GTX N770 Lightning

A bit too extreme, as it turns out last month, we reviewed two GeForce GTX 770 cards from Asus and Gigabyte that were well-cooled and only slightly overclocked. That’s too boring for MSI, which de­cided to take its flagship GeForce GTX N770 Lightning to an extreme not previously seen.

This bad mutha costs $50 more than a stock card, and with its massive cooler, is designed for hardcore overclocking straight out of the box. This ain’t no 20MHz overclock neither, but 104MHz on the base clock, and 117MHz on the Boost clock. You could theoretically take it even further, given the card’s prodigious cooler, but in testing we were unable to push it much be­yond its highly overclocked stock settings. We also experienced some stability issues, leading us to wonder if this extreme card was pushed a bit too hard at the factory for general consumption.

As a flagship GPU, you’d expect this card to be ballin’ and it is that. Not only does it use a Twin Frozr cooler larger than the land mass of Asia, but it’s also built with “mili­tary class» components throughout, and includes hardcore extras such as three headers for taking voltage measurements along with the appropriate cables, an extra- long SLI cable in case you want dual Light­nings, and an absolutely massive heatsink/ fan assembly. Additionally, the back of the card features an extra PCB directly under­neath the GPU core dubbed GPU Reactor, which helps provide additional power filter­ing. It’s removable for situations where it won’t clear a CPU cooler, but we left it on for testing as we had the room for it. When the card has power, it glows blue and is a great ice-breaker at LAN parties. The card also features a dual-BIOS switch with both normal BIOS and an LN2 BIOS for serious overclocking. Suffice to say, this is a premi­um card designed for crazy overclocks even beyond the default overclocked state.

As expected, the card was indeed the fastest GTX 770 we’ve tested thus far, but not by as large a margin as one would ex­pect given its price point. This card costs $40 more than the Asus and Gigabyte boards we tested last month, and the extra money is not justified, at least not for regu­lar desktop users.

An even bigger issue is that both cards we received for testing were not stable. The first card committed GPU suicide; the second card would hard lock the system running Heaven 4.0 at stock clocks. We tried underclocking 100MHz and saw improved stability, but that shouldn’t be necessary. Finally, just to make sure it was the card and not our test bench, we ran a stock GTX 770 card overclocked in the same test bench and had zero issues. We also ran the afflicted N770 on a second test bench, and it froze that system, too. MSI told us it had never seen a card with these issues, but our expe­rience indicates that buyers should proceed with caution.
