The Jetway is a very nicely laid out nForce 4 board with excellent adjustments, and we fully expected that we would be recommending the Jetway to those who run at stock or only modestly overclock. Well, our expectations were far too modest!! The Jetway turns out to be one of the best overclocking nForce4 boards that we have ever tested and moves right up there with the DFI SLI and Sapphire/ATI single video Innovation board.

The Jetway turned in one of the highest overclocks at the stock 12X multiplier that we have ever tested at 122% or a 244 CPU clock. Lowering HT to 3X, we also reached one of the highest overclocks that we have ever achieved at lower multipliers by hitting 314 at a 9 multiplier. What's more, the Jetway was exceptionally stable at both overclocks, handling Super Pi and other benchmarks with ease.

Getting to these stratospheric overclocks on air is not as easy as many may think. There are a number of design tricks that the best overclocking boards use to reach these high performance levels, which is why smaller companies often do quite poorly in overclocking. It takes design staff and attention to detail to create a great overclocker - resources that are usually in short supply at smaller companies. We don't know where Jetway purchased this design excellence, but we can tell you that the Jetway 939GT4-SLI is a dynamite overclocker - one of the best that we have tested. With a lower selling price, the Jetway gives AMD shoppers a new choice in an enthusiast-level board.

This brings us back to the earlier question of whether or not the dedicated slots with no paddles, jumpers, or switches might improve performance. It is clear that the Jetway performs very well in overclocking, and if this design is the reason, then others should copy the Jetway design.

    Table on page 2 says this board has 2 x1 PCIe slots but I see only one in the picture.
    Could you confirm this? Thanks.

    We are told the middle x16 slot can function as an x1/x2 slot when the outer two x16 video slots are in use (as SLI or dual video). While there is only one physical PCIe x1 slot, the ability to have two funstioning x1 PCIe slots even with full SLI persuaded us to list the slots as 2 x1 PCIe.

    Can I stick 3 dual DVI cards in there and hook up 6 monitors?
  • tanekaha - Wednesday, August 24, 2005 - link

    Thx for the heads up on this board Wesley
    Looks like many ppl in this thread would like 2 see the EVGA freebie reviewed
    Maybe, when ya get over your excitement, a review of the EVGA Bd would give you some more.
    Looks like a lotta ppl here would be into it as well.
    Thx again

    I ordered one of those EVGA combo's yesterday. From the looks of it some people are having a bit of a time with the EVGA BIOS holding the OC settings after a reboot. There is a new Jetway BIOS out that fixes this issue on their board. EVGA has not issued a new BIOS yet. If my setup has the same issues I'll prolly try the Jetway BIOS, against the EVGA forum mod's advice. Hopefully EVGA will just release their own BIOS fix in the next few days. That issue aside, the folks seem to be having very good luck OC'ing this board. I was going to wait for the ATI soloution but bit early. I like this boards 3 PCI/no jumper/bridge soloution.

    If they offered it in the all silver that they did some boards in Id jump on it.

    Is it just me or does the color scheme look a little too much like a preschool toy. I can see this motherboard perfectly at home in a lego computer case. I think a more subdued color palette would do wonders for the physical appeal.
  • lchyi - Wednesday, August 24, 2005 - link

    I would totally build a case out of legos and include this mobo.

    Pricewatch --> EVGA 7800GT $399 + MB for $129 = $528 (shipping included)
    EVGA site --> EVGA 7800GT $449 + EVGA SLI MB for $0 + 11.95 shipping = $460.95
    A savings of $67.50. Not a bad deal at all if EVGA's MB is as hot as the Jetway.
    What I am concerned about tho, is that the EVGA is priced $70 more than the Jetway. No wonder they are giving them away, they won't be able to sell any after word gets out about this.

    I saw the exact same board at monarch computer but it is an eVGA board and it too retails at a 939 AGP killing price of $129.
