FIRST LOOK: ULi M1697 for Athlon 64/x2
by Wesley Fink on December 13, 2005 12:05 AM EST- Posted in
- CPUs
As VIA and SiS seem to be declining in the chipset arena, ULi continues an aggressive push to capture a larger share of the chipset market. This is particularly true in the AMD arena, where ULi has produced the innovative AGP/PCIe M1695/M1567 chipset, and where ULi recently introduced the M1575 South Bridge for the ATI RD480 Crossfire chipset.
ULi also produces a single - chip Socket 754/939 chipset called the M1689, which is used by Gigabyte and other board makers for entry level AMD boards. However, the M1689 looks fairly basic in today's feature wars, which is exactly why ULi is introducing the M1697 single-chip for AMD Socket 939, 754, and 940.
Please keep in mind that this is not a board review. We are evaluating a ULi M1697 Reference board, and Reference boards are designed for qualification - not production. The Reference board will give you a very good idea of the features and capabilities of the M1697 chipset, but it is not useful to look too closely at board layout or overclocking controls, unless they are exemplary as in recent ATI Reference designs. In the case of the M1697, the Reference board is clearly designed for qualification, and feature demonstration. It is not a board that will be copied in production.
This is particularly true in the overclocking arena. While the M1697 has basic voltage adjustments and an excellent range of memory adjustments, there are no memory voltage adjustments at all on this board revision. As a result, we decided that it was not reasonable to do any overclocking tests on this Reference board, since we could not use our standard test methods to evaluate OC capabilities. This was an easy decision, since Abit and other manufacturers have assured us that we will be receiving ULi M1697-based motherboards for review in the very near future.
ULi M1697 Chipset
The ULi M1697 chipset can support Socket 754, 939, or 940. 1000 HT (5X) is fully supported.
In addition to the configurable PCI Express graphics slots, the remaining 4 lanes are also configurable. Several settings can be selected - 2 x1/1 x2, 2 x2 or one x4 PCIe slot(s).
The rest of the M1697 feature set is what you would expect in a competitive chipset. This includes 8 USB 2.0 ports, two (4 devices) IDE Ultra DMA 66/100/133, and Super I/O supporting Parallel, Serial, PS2, and floppy ports. ULi supports all the current USB transfer standards such as HS (480Mb/s, FS (12Mb/s) and LS (1.5Mb/s). Those who have watched Digital Camera makers play games with USB 2.0 transfer rates will recognize the terms HS or High Speed and FS or Full Speed. What they may not be aware of is the 40-times speed increase of High-Speed USB 2.0 over the inappropriately named Full Speed USB 2.0 standard.
The one disappointment in the feature list is the supported Ethernet. The M1697 has the hooks to support a 10/100 Ethernet PHY, but Gigabit Ethernet will require a discrete Gigabit LAN controller, preferably on the PCIe bus. This one feature tends to pigeon-hole this otherwise excellent chipset as a value solution. That is really unfortunate, since you will see the ULi M1697 is otherwise completely competitive with the best chipsets available for AMD Athlon 64.

The ULi Award BIOS provides a typical range of BIOS control options for a Reference Board used to qualify a chipset. The wide 200 to 400 range for CPU clock was a pleasant surprise, but it is somewhat academic with no memory voltage controls present in the BIOS. The memory tweaking adjustments were extensive, but of limited use without some means of controlling memory voltage. Reference Boards demonstrate chipset features and capabilities to manufacturers, and ULi clearly shows that the M1697 is capable of supporting whatever range of BIOS control or Voltage control features that the manufacturer might wish to implement.
The M1697 is not a board that will be mistaken for a production motherboard. You can see CNR and other risers in odd locations, 4 USB 2.0 ports on the bottom, and a range of PCIe slots that can be turned on or off to test various configurations. Reference Boards are distributed by chipset makers for qualification and not for production. It would therefore be a mistake to dwell on the Reference Board layout, except to say that Reference Boards often influence layout of production boards. IDE, SATA, video slots and bottom edge headers all work fine where they are located. However, we hope that production boards will take a different approach to the location of the 24-pin ATX power connector. Located in about the center of the board between the CPU and rear IO ports, there is really no good way to route the heavy cable. In the center of the board, you have to be careful not to interfere with air flow or operation of the CPU and memory.
The location of the floppy connector at the bottom of the board will be a long reach for floppy users. Many buyers don’t care about floppies any more, but if you still use them, the bottom of the board is an inconvenient and hard to reach location.
Overclocking
With an incomplete set of controls for overclocking, it was not possible to test overclocking using our standard OC setups. With production boards due for review very soon, the decision was made to delay OC tests until we reviewed production boards. This will remove the issue of testing with non-standard setups that make comparison of OC performance to previous OC results very difficult.
Memory Stress Testing
Since this is a new chipset, the best setting for tRAS was first determined. With MemTest86, tRAS performance was the same at tRAS settings of 6 to 11, with a bandwidth fall-off at 5 and 12 tRAS settings. This means that any setting from 6 to 11 tRAS will work well with this chipset. We chose to use a tRAS setting of 7 for consistency with other chipsets such as the NVIDIA nForce4 and ATI RD480.
The ULi M1697 Reference easily handles 2-2-2-7-1T timings at stock speed, as do almost any of the current boards for AMD Socket 939 from NVIDIA, SiS, VIA, ATI, and ULi. By default, ULi configured the Command Rate as 1T with a single pair of DIMMs in a dual-channel configuration. Two DIMMs in single channel mode required 2T Command Rate.
Running four double-sided 512MB or 1GB DIMMs is much more demanding than running two DS DIMMs, and ULi behaved as expected. Like every board that we have tested, except the DFI RDX200, we needed to drop the Command Rate to 2T with 4 DS DIMMs. With 4 DIMMs, the M1697 remained stable with the same aggressive 2-2-2-7 timings used for two DS DIMMs.

Tests used OCZ PC3200 Platinum Rev. 2, which uses Samsung TCCD chips. Most memory manufacturers now provide several speed bins of Samsung TCCD chips, so the equivalent current OCZ memory would be OCZ PC4800. All memory ran at 2-2-2-7 timing in all benchmarks.
We tested with the NVIDIA 7800GTX to provide the most up-to-date performance results in all gaming benchmarks. Resolution in all benchmarks is 1280x1024x32 unless otherwise noted. 3DMark and Aquamark3 benchmarks use “Standard Score” setup, which is 1024x768 video resolution. Also included for Reference is performance of the ATI X1800XT in all games on the ATI chipset Asus A8R-MVP.
Results for the ULi M1697 Reference Board running the NVIDIA 7800GTX are in red color. Test results for other motherboards running the 7800GTX are in blue. Reference results with the ATI X1800XT are color-coded orange.
General Performance
There is little to distinguish or detract from the ULi M1697 in Winstone benchmarks. For a chipset designed for low price that should be considered high praise. The ULi Reference is competitive with the best Socket 939 Athlon 64 boards that we have tested. Performance in Winstones falls in the center of tightly clustered performance.
Graphics Performance and Encoding
Gaming Performance
USB Performance
USB 2.0 performance has been a problem area for some chipsets, so benchmarks were run to test USB performance of the new ULi M1697. We ran our standard USB throughput test on the ULi M1697 using an external USB hard drive.
Our test method uses a RAM disk as our “server”, since memory removes almost all overhead from the serving end. We also turn off disk caching on the USB and Firewire side by setting up the drives for “quick disconnect”. Our results are then consistent over many test runs.
We use just 1GB of fast 2-2-2 system memory, set up as a 450MB RAM disk and 550MB of system memory. Our stock file is the SPECviewPerf 8.01 install file, which is 432,533,504 bytes (412.4961MB). After copying this file to our RAM disk, we measure the time for writing from the RAM disk to our external USB 2.0 or Firewire 400 or Firewire 800 drive using a Windows timing program written for AnandTech by our own Jason Clark. The copy times in seconds are then converted into Megabits per second (Mb) to provide a convenient means of comparing throughput. Higher Rates, therefore, mean better performance.
Disk Controller Performance
With the variety of disk drive benchmarks available, we needed a means of comparing the true performance of the wide selection of controllers. The logical choice was Anand's storage benchmark first described in Q2 2004 Desktop Hard Drive Comparison: WD Raptor vs the World . To refresh your memory, the iPeak test was designed to measure "pure" hard disk performance. The hard drive was kept as consistent as possible while varying the hard drive controller. The idea is to measure the performance of a hard drive controller with a consistent hard drive.
We played back raw files that recorded I/O operations when running a real world benchmark - the entire Winstone 2004 suite. Intel's iPEAK utility was then used to play back the trace file of all IO operations that took place during a single run of Business Winstone 2004 and MCC Winstone 2004. The drive was formatted before each test run and a composite average of 5 tests on each controller interface was tabulated in order to ensure consistency in the benchmark.
iPeak gives a mean service time in milliseconds; in other words, the average time that each drive took to fulfill each IO operation. In order to make the data more understandable, we report the scores as an average number of IO operations per second so that higher scores translate into better performance. This number is meaningless as far as hard disk performance is concerned, since it is just the number of IO operations completed in a second. However, the scores are useful for comparing "pure" performance of the storage controllers in this case.
Audio Performance
For audio testing, we used Rightmark 3D Sound CPU utilization test, which is the same benchmark run in our earlier nForce4 SLI and Ultra roundups. This benchmark measures the overhead or CPU utilization required by a codec or hardware audio chip. We tested performance using the latest version 2.1. Since we found that Version 2.1 yields different results from the earlier 1.24, we have only included test results with version 2.1.
It is important to point out that the latest ULi and ATI chipset motherboards have the necessary hooks to deliver Azalia High Definition audio. Those who have been complaining about the poor AC'97 audio present on most AMD boards should be very pleased to find Azalia HD on the ULi and ATI chipset boards. The nForce4 family does not offer the necessary chipset hooks to support HD Azalia audio.
Ethernet Performance
The one area where the ULi M1697 is disappointing is in their choice of an ethernet controller. Instead of using a Gigabit LAN, ULi only provided chipset support for a 10/100 Ethernet PHY. In practical terms, 10/100 is plenty of speed for most broadband connections, but with Ethernet quickly becoming the new standard, it is mildly disappointing that ULi still does not support Gigabit Ethernet on their chipsets. This is undoubtedly a cost-saving measure, but it mars an otherwise excellent AMD chipset.
Manufacturers can still implement Gigabit Ethernet with discrete chips, but it is more difficult to provide that solution on the preferred PCIe bus when there are no hooks for Gigabit PCIe in the chipset. Since most broadband ethernet connections barely tax 10Mb/s, this will really only matter to those who do sustained high-speed transfer of very large files over a true Gigabit network. Still, you should be aware that PCIe Gigabit Ethernet is always a better solution, and competitors are providing that capability in their current chipsets.
Our Take
When we tested the ULi M1695/M1567 chipset a few months ago, NVIDIA nForce4 was the only real competition. Today, both the NVIDIA nForce4 family and the developing ATI Rx480/580 family are competitors in the AMD Athlon 64/x2 market. The natural question today is: How does the ULi M1697 compare to the excellent performance of the NVIDIA nForce4 and the ATI RD480? Since the real competition is the now mainstream NVIDIA nF4 SLI/Ultra and the ATI Rx480 Grouper/Crossfire, we would have to conclude that the ULi 1697 competes very well indeed. The M1697 gives up nothing in performance to the NVIDIA or ATI chipsets.
There should be concerns, however, if your AMD plans include SLI or Crossfire. ULi has all of the right features in their M1697 for SLI and Crossfire to work - that is not the concern. It is just that ULi is not a GPU maker, and they, therefore, are not in a strong position to ever expect support from NVIDIA or ATI for SLI or Crossfire on the ULi chipset. We're sure that both NVIDIA and ATI would be happy to license ULi, but it is doubtful that a value chipset like this ULi could afford the licensing fees and still be attractive to manufacturers trying to build a better mousetrap. The best hope in this arena is if the market were to move to an Open standard where all dual-video solutions work on all dual PCIe slot motherboards. We don't know when or if this will happen, but it is certainly the kind of development that would make SLI/Crossfire a mainstream solution.
This is closer to a reality in the Intel chipset market where Intel and ATI both support Crossfire and NVIDIA goes it alone. But the ULi is an AMD solution, and in that arena, the dual x8 will be useful for running two video cards, but not for running SLI or Crossfire. ULi does have a relationship with ATI so perhaps a technology exchange is a possibility for Crossfire. The best hope, however, is that SLI/Crossfire will become an open cross-platform standard. We can certainly dream.
From a features standpoint, the ULI M1697 compares very well against the current best in the Socket 939 market. It provides both HD Audio and SATA2 - something no other discrete AMD chipset currently provides. The SATA2 and IDE both provide excellent performance, and the USB performance is certainly competitive. Based on the low pricing that we have heard about with this M1697 single-chip solution, the feature set is all the more outstanding. The only failing is that 10/100 Ethernet is the only version supported directly by the chipset. The world has moved to Gigabit Ethernet and ULi will quickly find that this will become an issue unless they address Gigabit LAN support in future chipsets. The limitation of 10/100 direct support for Ethernet also has the unfortunate distinction of labeling the M1697 as a budget chipset. That's really regrettable, since other performance areas are anything but budget.
Until the SLI/Crossfire question is resolved, the real market for M1697 will be the nF4 Ultra and ATI Rx480 Grouper. At the expected very low price, the M1697 should compete very well in this market - providing the HD Azalia audio that is missing from nForce4, and the SATA2/competitive USB missing from ATI with the ATI SB450 south bridge.
Undoubtedly, there will also be ULi M1697 boards with dual x16 PCIe slots. They may be useful for running two video cards feeding different monitors or running specialized x8/x4 cards. However, the lack of real SLI/Crossfire support will limit how competitive ULi can be in this market. If ULi licenses SLI or Crossfire, we could be really positive about their prospects in the mainstream SLI/Crossfire market. Or, if by some miracle, the dual video card market opens up with broad driver support, the ULi M1697 will be much more attractive.
ULi continues to build some of the most interesting chipsets that we have tested in the AMD market. Unfortunately for ULI, not many manufacturers have been willing to produce new boards with the new ULi chipsets. We understand that the M1697 will see the light of day from some Tier One manufacturers. Abit also tells us that they will be producing a ULi M1697 that fully exploits the chipset capabilities. We are anxious to see where manufacturers will position the ULi chipset. If the production boards also perform well as Enthusiast-oriented boards, the ULi M1697 could certainly become a strong player in the bang-for the-buck market. If SLI/Crossfire support appears, the ULi M1697 chipset could be even more.
