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

ULi M1695 Chipset
The ULi M1695 chipset supports Socket 754, 939, and 940. 1000 HT (5X) and higher are fully supported.
The M1695 provides a PCI Express Interface that can drive either 1 x16 slot of 2 x8 slots. The 2 x8 configuration is called SLI on NVIDIA motherboards, and the option of x16 or 2 x8 is even available in this Reference Board BIOS.
ULi has even been showing an x16 riser card that can be used to support 2 bridged x8 PCIe video cards from a single x16 PCIe slot. Apparently, this is just one of several options to provide "SLI-like" performance with two PCIe cards.
From this basic PCI Express Tunnel chip, ULi talks about flexibility.
Combined with a M1567 South Bridge, as is this Reference Board, you can achieve AGP 8X and PCIe x16/2 x8 combined with support for PCI graphics.
Combining M1695 with an unnamed ULi South Bridge can provide dual x16 slots and additional x1/x2/x4 slots.
Obviously, ULi designed M1695 and the accompanying South Bridges for the utmost in flexibility. With support for 754/939/940 and all the various combinations that can be used to provide custom graphics capabilities, you will likely see many different ULi configurations in the marketplace.
The flexibility even extends beyond the ULi brand, as the South Bridges can be combined with other North Bridges such as the ATI Crossfire. Similarly, the M1695 can be combined with other chips such as the AMD-8132 PCI-X Tunnel for customized Workstation/Server Applications.
More capabilities can be added with more ULi South Bridges on top of the M1695/AMD-8132.
ULi talks about the flexibility of their M1695 chipset, and we certainly agree. It is refreshing to see so many available choices that give manufacturers the options of building everything from the most basic Socket 754 boards to full-featured 939/940 workstation/server boards with dual x16 PCIe slots and more.

Sorry if I missed this, but any word on when we're going to see this chipset in retail?mino - Friday, July 15, 2005 - link
I believe there are many typo's. A least this:"...Ventilation was just able..." should be
"...Ventilation was just NOT able..."
and
"... 5°C higher temperature..." should be
"...5°C higher temperature than outdoors in average..."

#59 Yeah, thats right. I just didn't want someone to fell in mistake by believing val on his 20W figure. I have to explain this a lot of times and it is sometimes hard to undo the damage done.val: actually I live in central Europe and here 1kWh costs ~ EUR 0.15 which IS cheap in Europe. I have made my own measurements and the problem is only 6xx series chips consume some reasonable amounts of energy. If they tested some older 5xx series model teh idle consumption easily reaches 120W with i865G while our AMD systems on SIS755/R9200 consume about 70W in C'nC mode and those are 130nm Newcastle chips !.
Try this: place 30 of those machines in classroom without clima and here is the difference:
Prescotts(Q3/04 530's) are overheating any time you trow something heavier o them. This poorly insulated room is ~30°C in the winter with heating OFF(outdoor -10) !!! Despite they bought LCD's to conserve space, after this summer courses they had to install clima for about 1/4 price of the whole IT instalation bought last year. The room was simply unusable anytime outdoor temperature reached 20C or more. Ventilation was just able to come around the problem since many could not work in the wind.
This happened on another faculty we are sharing building with. In similar room (+/-0.5m, same situation) we have 30 A64 3000+ Newcastle chips w/Radeon 9200 passive cards. The machines are (except heavy multitasking which is rare there) equally powerfull but more responsive _and_ more reliable. The enviroment is also ways better, in the summer there only about 5°C higher temperature in average with moderate ventilation(one window). Clime would certainly help, but we consider investing into another IT room more important at this time. Now I'm happy my arguing last year time brought some fruits
The prescott machines have to date(3/4yr timeframe) about 30% failure rate. Mainly caused by underrated power circuitry on MB's and PSU's. I know, they should have bought better PSU's. But that would only extend the price delta of 10% at the time of purchase (same suplier). I still remember how my friend from IT dep. of that faculty laughed at me then how stupid I am by using so underdog and unreliable config for our project.
To sum it up:
1) Prescott will have to cost $50 less to assure same reliability system at the same price/perf as A64
2) If 1) is fulfilled(i.e. some Dell machines) such a system could a good buy for causual use and definitelly a sngle choice if heavier multitasking is a must.
3) However for larger and especially for dense envirements prescott-based solution colud be a real pain in the ass.
4) 6xx somwhat improve this but after arrival of 90nm A64's just com pensate for AMD's improvement in power consumption thus the absolute delta remains approx. the same, the relative one even worsens.
5) On hugely positive aspect of prescott's existence is undoubtedly the fact that it forced even the cheapest case manufacturers to make some arflow in the case. I believe this could not have been achieved byt any other means that prescott. For that we should all be really thankfull.
huh, jet another novel ;-(

why are you people arguing over power consumption, its irrelevant to the topicval - Friday, July 15, 2005 - link
München last year wasted only for people's comfort (more often street train than would be needed) over 270 MW hours.This means 1.000.000 people gaming whole year 3 hours a day. For stupid people comfort.

#54 one mid size advertising panel on building takes about 20000W, you have in USA them on one street more than we have people in some villages.And i hope that you and all your hippie friends are not using plasma TVs or worse CRT TVs and monitors to screw my nature.

#54 i know, but i am trying to tell you, that one useless powerplant only for military researches will cover milions of people possible waste. Who cares power plants, you change nothing.What i am saying is, that if it would be important, people should first STOP USING THEIR CLIMA, change the bulbs to energy efficient ones, do YOUR MATH.
Minos bulbs harm the world much more than mine pc!
And how much takes your clima? Your hot water collector?! use brain please. You cannot tout on intel for poor 100W of average use no more than 2 hours full PC load.
Your car damages nature and costs you more than difference to me having some VIA cpu to save your nature. Get it to your head.
So stop talk like hippie.

So can this board handle 2 ATi cards if one is a crossfire or it just for Nvidia SLI?nserra - Friday, July 15, 2005 - link
#52200 euro for you, but 200 euro x 10.000 people is 2.000.000€.
I win 800€ month, make the 2.000.000€/800€ how many months of salary is it?
Isn’t just 20W as you say, it's 20W to 100W. You are right that people aren’t playing games the all day, but is the all day idle? , in fact put some complex 3D screen saver and you will see how idle it is.
Also 20W for you but 20W x 10.000 people is 200.000W (best case scenario), but if it's 100W x 10.000 people its 1.000.000Watts!!!
So do you your math, because the world isn’t just you!

#50 while intel usually works from first release when the mobo brand quality is not underestimated.
