SiS755 Reference Board: Athlon64 from SiS

Content Creation, General Usage and Memory Performance
The SiS755 Reference Board performs as well as any Athlon64 board that we have tested in Content Creation. In General Usage, it is surprisingly the equal of the heavily-tweaked Abit K8V-Max3 and performs at about the same level as the Gigabyte FX51 board. This is really outstanding performance and we look forward to seeing production boards based on the SiS755 chipset.
Science Mark 2 was recently updated, and we used the latest 9/23/03 build for our Memory benchmarking. With the memory controller on the Athlon64 processor, we really expected memory performance among Athlon64 chipsets to be about the same. The SiS755 was a pleasant surprise in posting the lowest latency figures that we have yet seen on an Athlon64 chipset. SiS755 was also a bit faster than VIA K8T800 in ScienceMark memory bandwidth, making it the fastest Athlon 64 chipset so far. The performance differences, however, are small, and are most likely explained by the 2-2-2-6 memory timings supported on the SiS chipset compared to the 2-2-3-6 timings that were required on VIA's offering at DDR400.

Lets Bench IT!MoronBasher - Saturday, December 6, 2003 - link
I have a sis 746, and 735 and i can't wait for this chipset to come out!!!mason - Thursday, November 27, 2003 - link
Great review!Two things -
1. The SIS reference board is almost always the fastest performing board with that particular chipset. I think it's premature to label it a winner until you can find a decent performing production board.
2. SIS has been making great chipsets for the Athlon since the 735, only no one knew about them because they typically ran second to VIA in memory banddwidth, which was what all the major review sites cared about. The HDD performance and overclocking headroom on the 735 and 745 both outclassed the VIA boards (KT266, KT266A, KT333) of the day, but they were hard to find and few manufacturers made anything better than cut-rate boards.
The MSI 745 Ultra and the Leadtek 735 board were possibly the best of the early generation SIS athlon boards.
The current SIS748 chipset for the athlon 400FSB is actually very good, though again slightly slower than the KT600 is memory bandwidth.
I just wish major sites would review the few boards that do use these chipsets, so we could start seeing higher quality boards like the DFI 748.

buy now.....asus k8v is an awesome board, in 2 months you might as well wait another two months, and another.....jeeptreker - Wednesday, November 26, 2003 - link
Purchase timing is my concern. I'm considering the AMD 64 3200+ & the Chaintech ZNF-150 w/ nForce3-150 chipset for Christmas. Am I on the edge of a change? If I wait a month or 2 will the AMD 64 3400+ and SIS755 or nForce3-250 chipsets be out? If these items won't be out for 6 mos. then I'll just be chasing technology.Buy now or wait? Any suggestions will be appreciated.

When should we expect motherboards based on the SiS755 chipset to reach retail chanels?NFS4 - Tuesday, November 25, 2003 - link
I'll wait til I see the performance of shipping boards before I jump ship...reference boards tend to be "tweaked" in some case. I'm currently lovin' my VIA K8T800 based Asus K8V Deluxe.justly - Tuesday, November 25, 2003 - link
"To our surprise, SiS755 also provided the best performance in AnandTech benchmarks of any Athlon64 chipset that we have tested."Did this realy surprise Anandtech? it didn't surprise me.
For quite some time SiS southbridge chips have proven to be well designed, in fact whenever disk preformance was tested SiS has had some of the best scores. The main problem SiS has had in the past was with the performance of their memory controller. So it would only make sence that when the memory controller is no longer a concern, as it is with the Athlon 64, SiS would be able to show of its southbridge performance.
Other than your surprise about the performance I thought it was a good article. I hope Anandtech doesn't ignore future SiS (or ALi) AMD solutions like it has in the past with socket "A".

I noticed your description of the erratic booting/stability behavior when overclocking which is similar to overclocking problems described in the ipkonfig article-today's AT news post:http://www.ipkonfig.com/Articles/AMDCastrated/Page... .Is this due to data corruption in the HT link as a result of CPU speed being linked to the HT link speed?

I think performance will be influenced most by how "streamlined" everything in the chipset is (i.e. IDE drivers at maximum performance, things such as LAN and RAID taken off of the PCI bus and put on the Southbridge).
