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.

Maybe a lil OT, as it applies to any SLI board, but:Can you run a video card in one of the green slots and then use a PCIe RAID5 card, like the Areca x8 RAID5/6 8 port SATA card?
I do need RAID5, I run a development web server with a SQL server on my PC.

I would guess yes, since you can throw a 1x device onto 16x slot and they work fine. Of course your graphics performance will be slightly worse, but the difference should be negligible.Leper Messiah - Wednesday, August 24, 2005 - link
$129 SLi board with this kind of performance? I'm there! Dual core 3800+ Jetway mobo, and an x800xl or something for now seems to be very tempting right now...slsmnaz - Wednesday, August 24, 2005 - link
Why is an SLI board w/ an x800xl tempting?OvErHeAtInG - Wednesday, August 24, 2005 - link
Because he could upgrade to 7800 GTX/GT SLI's when the price comes down.ncasebee - Wednesday, August 24, 2005 - link
You are sure that this is the same board as the one included in EVGA's free mobo deal? If it is, I see no reason not to get this board, and save myself the money.Furen - Wednesday, August 24, 2005 - link
You could always ask EVGA directly... say something like "I've heard good things about the Jetway motherboard and was wondering if they are manufacturing it for you" or something of the sort, heh.Furen - Wednesday, August 24, 2005 - link
OK, I went into EVGA's support forums and though the motherboard is a rebranded Jetway they are pretty behement about you not using the Jetway bios. It might just be them throwing a bit of FUD at you but I just wanted to point it out. By the way, it seems that their current bios is a bit flaky on the overclocking front (Jetway's has already been fixed, it seems).Calin - Wednesday, August 24, 2005 - link
than on other boards made by Jetway. We had one board (from several bought less than three years ago, in several months) gone bad - the capacitors were dead.Other than that, I wonder if one could use all three PCI-E slots (having one 16x card and two 8x cards), and if not, a chipset change could solve that

Remember that this is just a paddle-less design. With the paddle you can't use the 2nd PCIe x16 slot if it is set to single mode; you need to switch the paddle to dual mode which cuts it to two x8 slots each physically having a x16 connector. Either way, there are only 16 usable lanes.It's the same thing, plug a card in the yellow and the "paddle" is set to single x16; plug a card in the green and the "paddle" is set to dual x8.
