FIRST LOOK: ULi M1695 PCIe/AGP Socket 939 for Athlon 64

As we reported form Computex, the talk of the show was ATI's new Crossfire dual-video solution for AMD and Intel. Part of that talk was the development work done with ULi on the ATI South Bridge and the cross-compatibility of the ULi South Bridge using the ATI chipset. ULi is what remains of the ALi chipset division of Acer, and this now independent chipmaker has been very busy in several arenas. In addition to South Bridges which can work with the chipsets of other manufacturers, ULi also makes single-chip and dual-chip solutions for Athlon 64.
ATI certainly had the spotlight with their new chipset, but one of the newest and most interesting chipsets introduced at Computex was also from ULi - the M1695 HyperTransport PCI Express Tunnel Chip for AMD Athlon 64 platforms.

"M1695's innovative HyperTransport tunnel architecture integrates non-blocking symmetrical HyperTransportTM 2.0 links which enables motherboard manufacturers and system integrators to pair up M1695 with other high performance HyperTransport-based chipsets and bridge devices either natively or via the HTXTM connector. When coupled with ULi's M1567 south bridge, the combination offers motherboard manufacturers the unprecedented capability to support PCI Express x16, AGP 8X, PCI graphics cards simultaneously on the same mainboard. Such capability makes it possible to create a fully surrounding virtual reality environment using multiple high resolution displays driven by the three graphics technologies residing in the same computer system."

#12 - This is a First Look with 2 days testing time for the review. There is a followup Reference Board with better options and we will be analyzing disk and I/O on that board. Testing 10/100 Ethernet tells us little about the board. Abit and Gigabyte both have full-blown boards in the works.#15 - The drivers were trouble-free in our testing. Reference Boards are famous for quirky drivers but these worked as they should.
#20 - 400 IS the speed when I set 200 Clock Speed in BIOS, so I am talking about 400 Clock Speed (800). It isn't truly FSB on an HT machine, so I've changed the wording and the DDR reference error to make it better understood. We are expecting the second Reference Board with improved overclocking shortly and will do more testing for a Part 2 with that board.

Wesley Fink i noted that the speed of the AGP is very good, but vs the older 1689 is it equal, higher or is the 1689 even higher. Can you do some 939A8X-M test just to check.#20 He mean 400Mhz. Thats a typo.
Uli say their chipset would do 400Mhz bus speed i just dont know it it's 400x5 or 2000 HT.

Page 4 Overclocking - "Since there were no voltages for memory, we had to toss our normal overclock procedures out the window" and "Without memory voltage, the only way that this can be tested is by lowering memory ratios to those that can run at default voltage"Since you like promoting OCZ products and they seem more than happy to send you them (you used OCZ memory and PSU for this test), why not ask OCZ to send you a pair of their DDR Booster things?
From the same paragraph- "We have seen reports that this new ULi Reference Board, or more specifically the sister Reference Board with the dual 8X riser slot, can reach a FSB setting of DDR400"
Reach an FSB setting of DDR400? Isn't that the default memory speed anyway? I certainly hope it can reach DDR400! :) Did you mean that it can reach 400MHz FSB?

This is fantastic. I was wanting a skt939 mobo in a server but all the PCIe RAID boards I've seen need an 8x socket which currently nothing except servers support in tandem with a gfx card. The fact that you could get more than 20 lanes is brilliant news for me :)SynthDude2001 - Wednesday, July 13, 2005 - link
#17 - OMG. I want one now!Any ideas if this will be able in the near future too? (Say, within a month or maybe two)

If you need Linux driver support for ULi chipsets, head to ocworkbench.com forums OR search/contact ULi about it.I know the previous generation, M1689 chipset did work without a problem in Linux. (I used Fedora Core 4, Gentoo and Slackware).
I was already excited about this chipset (M1695) MONTHS ago...It must take quite a bit of time to get the word out from Taiwan to USA.
If you thought the chipset was interesting.
Check out what ASRock is gonna do with it!
They have a mobo under development that uses this chipset and have an upgrade option to support future Socket M2 CPUs.
Don't believe me?
ASRock 939Dual-SATA (formerly ASRock 939Dual-M2)

SO what do we have here?
(1) PCI-Express and AGP support (no performance loss)
(2) SLI capable. Over at ocworkbench, they have an article which demonstrates that the M1695 DOES support SLI. The special dual PCI-Express 8x riser card is only a prototype (consider it a concept demonstrator), and NOT a retail product...Either way, SLI on M1695 works...And performance is identical to NF4 SLI.
(3) Dual-core support. (both the older M1689 and newer M1695 can handle dual-core without issues).
(4) Overclocking. (ocworkbench.com has shown the newer M1695 has PCI/PCI-Express/AGP locks, and it can handle very high overclock bus speeds)...The current M1689 does NOT have PCI/AGP locks. So ULi did listen to the enthusiast crowd. :)
(5) Upgradeability (ASROCK only)...Who wouldn't want a mobo that supports Socket M2 as well as Socket 939? :)
(6) Its marketed to be slightly cheaper than VIA chipsets!
(7) Abit, ASUS, ASRock, Gigabyte are some mobo manufacturers that have released mobos based on ULi chipsets, and they're working on products with the newer M1695.
Its not surprising that ULi is offering so much. They have been noted for saying they want to be the very best Taiwan based chipset provider. And from the looks of it, they're getting there quite well with the M1695.

Quality drivers will make or break the deal on this chipset.Quality Hardware counts too, but drivers are a deal maker or breaker.

Absolutely amazing. Assuming they allow for a bit more overclocking options (voltages mainly), and that it does appear in August like they say it will - this WILL be my next motherboard.My 6800GT still has a lot of life left in it I think, but the Athlon XP finally needs to go. I can pick up an X2 and one of these boards, use my 6800GT for now, throw in an R520 or '7800 Ultra' later, and probably be set for at least a year, maybe two.
I can't wait to see these appear at retail!

Thats the most important thing for ULI right now. They need somebody, ANYBODY, to make a board with 2 physical PCI-Ex 16x slots AND agp 8x. The riser card is great in that it proves that it works (and that SLI works as fast as a Nforce 4 SLI board as seen on OCWorkbench), but it aint going to fit in any case that ive seen. 2 PCI-Ex 16, an AGP, 2 PCI, and a PCI-Ex 4 slot... and we got one beautiful board.Judging by past ULi/ALi pricing, it will be dirt cheap too. Actually, i dont think we need to worry so much about whos gonna make it... a quick search on Newegg shows that ASRock, Gigabyte, Abit, Albatron, and Chaintech are all making boards based on the less exciting 1689 chipset.
Im excited. Amazing AGP performance, solid PCI-Ex performance WITH full on SLI, and a low price. Perfect for a few upgrades to K8-ville.
