OCW Review : Jetway 939GT4-STD-G

[bluetooth]

<center> </center>

Jetway might not be a familiar brand to most of our readers but they have been very active in developing innovative products. If you read our Computex 2005 coverage, we brought to our readers attention to this special board which features a 3 slots PCI-Ex16 Mainboard. At first glance, we were wondering how do they support 3 slots? 4+4+8 ? 4+16 ? How is it configured? In the review, we take a look into the board's design and specifications.

Jetway 939GT4-STD-G is based on the nForce™4 MCP single chipset and supports the Socket 939 processor. A look at the mainboard shows a single yellow PCI-E x16 slot. From the manual, it is clear that Jetway's design is to simplify installation of SLI. To enable SLI, just install the two cards into the green slots and bridge it using the SLI bridge (not provided in the package).

The mainboard supports 3 * 32-bit PCI Slots / 1 * PCI EXPRESS x1 / 3 * PCI EXPRESS x16, 4 * Ultra DMA 133 / 100 / 66 / 33 for expansion. It also comes with 8 USB 2.0 ports, Marvell 88E1111 GbE LAN. Realtek ALC 850 8 ch audio. The mainboard uses embedded OC-CON high-polymer solid electrolysis aluminum capacitors for better overclockability.

The BIOS also comes with lots of overclocking options which is definitely something worth a look in the next few pages.

Jetway has not had a good reputation in the past but that all seems to be behind them. Performance and stability look good as does build quality, and innovation cerainly points to good things. Looks like another under dog is about to steal the bone from the big players :D

hey bluetooth!
it looks like jetway wants to compete with companies like dfi. i see high quality inductors, mosfet heatsinks and vdimm up to 3.25V!! although if i buy this mobo,i'd prolly tie vdimm to the 3.3v rail and raise it to something like 3.5V

I'm really interested in buying this mobo.
could you test it with some BH5 or UTT at max vdimm? see how far it can go 1:1 2-x-2-2 1T.

also, why was your ddr600 overclock only at 8 multi? you cpu limited for sure or is this the board? i know some nf4 boards only oc'd well at low multis.
also, what was the htt multiplier at 330htt?

anyway, thanks for delivering a good review [img]tongue.gif[/img]

hi Goatman,

Firstly, that board is based on NF4 STD chipset and not NF4 SLI chipset. THere is another version which uses the NF4 SLI chipset.

What would be your expected 1:1 CAS 2-5-2-2 1T ? Give me a target.

MY FX-53 isn't that good in overclocking. Furthermore, I didn't run the ram in Sync mode. Htt multiplier used was 3x or 600MHz.

Spread and share the link with others.

>>Firstly, that board is based on NF4 STD chipset and not NF4 SLI chipset. THere is another version which uses the NF4 SLI chipset.

yea, i know, but it's really the same board - sli enabled - sli bridge.

i think some good utt/bh5 should do at least 240,
250 would be the max i would expect from bh5/utt on any mobo at 3.25V

I actually have a DFI NF4 ultra-d board in my main system. It works fine with tccd/utt, but my bt-d43 that did 315 super pi-stable at 3V in my old asus a8n sli deluxe can't go above like 220 in the ultra-d. :S unfortunatly, i sold my a8n sli deluxe to get my dfi board.

>>Spread and share the link with others.
yes, i have poted a link to your review on a few forums. I get mostly unsure opitions about this board. I think when more people have them DFI might get some competition. right now i don't think any other company offers things like vdimm over 3V except abit with their Fatal1ty AN8 SLi.

eww what a retard [img]tongue.gif[/img]

edit: just had a quick google
http://insanetek.com/index.php?page=abitfatal1tyan8_5
vdimm only goes up to 2.8V
that's what i'd expect from a budget board

edit2: Gigabyte GA-8N-SLI Royal can do 3.2 or so volts.
however this is an expensive and over-bloated mobo. next thing you know we'll have gravy pressure sensors. [img]tongue.gif[/img]

btw, do check out the ULI ref board on mainpage, overclock to 400HTT easily.

[goatman]

yea i saw that, that's bloody awsome!
hopefully ULi get a license for SLI!
I guess unlike sis, uli still belives in the retail market. If only sis had done a little more advertising, and a little more work on improving overclockability, it's 655TX chipset wouuld have taken off.

Who knows. anything is possible these days. NVIDIA might be crazy enough to open up their drivers, so every chipset maker can come in and make compatible SLI systems? Maybe we shoudl ask them to do so ? [img]smile.gif[/img]

[goatman]

I doubt they'll listen but it's worth a try.
BTW, do you have time to test the jetway board?

cheers [img]smile.gif[/img]

Which jetway board? I thought the review is already posted- the JETWAY SLI board.
