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.

I bought this board recently from newegg but haven't tried it out yet. What is the purpose of the power connector immediately above the PCI-E x1 slot? I thought it might be used for extra power for the PCI-E cards but then with 24 pin moboard connectors and graphics cards with their own additional power connectors, isn't there enough power already? Also, nowhere in the documentation nor reviews of this board on other hardware sites do I see any indication that this board supports SATA-2. Wesley, where did this info come from?raildogg - Thursday, September 1, 2005 - link
guys, I've heard that they are the identical boards, however, some of their specs may not be. are they the exact same boards? not surecheck this out

yeah ok..but the eVGA board doesn't have 3 PCI Express x16??At lease they dont state this infomation on the site(Newegg link you gave)..Now if the jetway bios updates the evga board to the same state then I think it could make a great buy..And yes they both(eVGA&jetway) need to make there colors a little make adult like.

Look at the Newegg EVGA pictures. The EVGA board does have 3 x16 slots. The Newegg specs are not in agreement with the pictures. and the pictures match other EVGA pictures and specs we have seen. The EVGA and Jetway appear the same board with different BIOS. Many Forums are reporting success with flashing the EVGA with the Jetway BIOS.inkysowner - Wednesday, September 7, 2005 - link
Hi Wes,I have the evga board and the same memory 2x512 with 2 evga 7800gtx's(acs kits in the box), just want to verify this.
"Tests used OCZ PC3200 Platinum Rev. 2, which uses Samsung TCCD chips. All memory ran at 2-2-2-7 timing in all benchmarks."
So at 12 x 244 you were running 2-2-2-7 Command 1T and at what voltage.
I have a 4400+ that I am trying to get up near 2.7 and at the stock multi of 11 and those timings at 244 I should be in the sweet spot, I think the aquagate-mini should be able to cool the processor enough at those settings, esp based on the new inquirer article review of the coolermaster aquagate mini-120 which I have in a cm stacker.
Thanks in advance

There are now several reports on the web of eVGA users successfully flashing with the latest Jetway BIOS. Users are also reporting that the Jetway BIOS offers more options and better overclocking that the eVGA which appears otherwise to be the same motherboard with a different, more subdued, color scheme.kennyG - Sunday, September 4, 2005 - link
do you have any links..I'd like to read what others are getting as far as overclocks ?Fozzik - Thursday, August 25, 2005 - link
I noticed that pretty much know I/O benchmarks were run...Do we know that this board doesn't have any glaring problems with onboard NIC, USB, etc? The new Sapphire boards based on ATI's Xpress 200 chipset look great, except for seeminly (an difficult to explain) lousy performance of their integrated divices on the PCI-Express bus. I know this isn't the same chipset, and that all Nforce 4 SLI Implimentations are probably similar...but I'm just wondering since none of those benchmarks were included in this review. Let's get right down to it... I'm paranoid about Jetway. ;) Usually when things look too good to be true, they are.

We have already tested I/O performance of all of the chips on the Jetway board, so we saw no valid reason to retest the IO performance. The Marvell PCIe PHY for Gigabit LAN is an excellent performer and is just a Physical Layer to the nF4 chipset Ethernet hooks. SATA 2, USB and IDE are controlled by the nForce4 SLI chip, there is no onboard firewire or additional SATA 2 controller, and the Realtek ALC850 audio codec is used by almost every nF4 motherboard.Fozzik - Sunday, August 28, 2005 - link
Thanks for the reply. =)
