Networking

The Windows 2000 Driver Development Kit (DDK) includes a useful LAN testing utility called NTttcp. We used the NTttcp tool to test Ethernet throughput and the CPU utilization of the various Ethernet Controllers used on the Intel motherboards. We set up one machine as the server; in this test, an Intel system with an Intel CSA Gigabit LAN connection. Intel CSA has a reputation for providing fast throughput and is a logical choice for our Gigabit LAN server.

On the server side, we used the following Command Line as suggested by the VIA whitepaper on LAN testing:

Ntttcpr -m 4,0,‹server IP› -a 4 -l 256000 -n 30000

On the client side (the motherboard under test), we used the following Command Line:

Ntttcps -m 4,0,‹client IP› -a 4 -l 256000 -n 30000

At the conclusion of the test, we captured the throughput and CPU utilization figures from the client screen.

Networking Performance - Throughput

Networking Performance - CPU Utilization

Our network throughput test indicates how well a particular controller design from Realtek, Marvell, or Intel performs instead of being indicative of true chipset performance. This also holds true for the CPU utilization results, though this test can also be influenced to certain degree by the BIOS code and chipset interconnect design.

The CPU utilization and throughput numbers favor the Realtek controller on the Gigabyte board, followed closely by the same Realtek chipset on the Foxconn and ASRock boards. In practice, few if any users will notice a difference, even if they have the requisite gigabit hub, as storage performance frequently bottlenecks the actual transfer rates.

For our second series of networking tests we utilize a Promise SmartStor NS4600 NAS unit equipped with two WD Caviar Black 640GB drives in RAID 1 operation. We are using two benchmarks from Intel’s popular NASPT 1.70 testing tool. The Promise NAS unit is connected to each test platform via a NetGear Gigabit Ethernet switch. We left all settings at their defaults on both the motherboard and Promise NAS unit. Our was to maximize the performance of the NAS unit to verify our network throughput capabilities on each motherboard.

Networking Performance - File Copy to NAS

Networking Performance - HD Video - Play/Record

Our three P55 test subjects perform almost identically in our actual usage tests.

USB / FireWire Performance

Our USB transfer speed tests are conducted with an USB 2.0/FireWire based Lacie external hard drive unit featuring a 1TB 7200rpm Samsung drive . In the SSD to External test, we transfer a 3.82GB folder containing 2735 files of various sizes from our Kingston 80GB SSD to the Lacie drive. In the next two file tests, we use the same 3.82GB folder to transfer from our WD VRaptor 300GB hard drive to the external Lacie drive utilizing the USB 2.0 and IEEE 1394a interface.

Storage Performance - USB - SSD to External HD

Storage Performance - USB - HD to External HD

Storage Performance - Firewire - HD to External HD

The ASRock board slightly outperforms the Gigabyte board in our USB transfer tests. The VIA Firewire controller on the ASRock board has a slightly higher write speed (+3Mb/s) under HDTach/HDTune and it shows up in our file transfer test.

Storage Performance

In our storage test, we utilize the same 3.82GB test folder and transfer it from our WD VRaptor drive to our Kingston 80GB SSD.


Storage Performance - HD to SSD

Once again, our P55 motherboards perform almost identically. The P55 chipset on the Gigabyte board has a 3% advantage over the JMicron controller on the same board. However, any measurable differences were not recognized in actual usage.

    how do you get 4 phase on the GA-P55M-UD2? looks like 6 by the photos? bit-tech says 6 too.
  • andersbranderud - Friday, March 12, 2010 - link

    Does anyone have any experiences with overclocking an i7-860 on this motherboard with 1333 mhz or 1600 mhz ram.

    In that case give me some more details.

    Thanks!

    Was looking at picking up GA-P55M-UD2 for a HTPC, going to pair it with Core i7 860 and a ATI HD 5000 series card. Wanted to know if there was any problems with this board to do the bit-streaming of HD audio or if the UD4 would be better suited?

    I don't see how the inclusion of something can be seen as a negative. I am sure there are a few users who still depend on a floppy drive from time to time (retro dos gamers, some drivers, and archiving old files) and it's presence has little to negative impact on the actual usability, functionality, or performance of the motherboard.

    As for my self, I have tried several times to remove my drive, only to have someone or myself find an unexpected need for it a few months later. So I still keep it installed but the drive it's self remains disabled in the bios until I actually need it. Having it enabled has no noticeable impact on my P4 based system.

    Hi Gary,

    Nice review. I am planning to buy a p55 mATX board. There are some on the market but mostly they support only 16x & 4x GPU and thats a pity.

    Only the Gigabyte GA-P55M-UD4 and ASUS Maximus III Gene support sli/cross at 8x mode. I would like to your review about these boards soon. The price for the GA-P55M-UD4 is available around € 130.- incl. VAT and the Maximus III Gene around € 170.- incl VAT.

    Thats why I probably go for the Gigabyte due to the price an the board colors, but the board layout has some fails and according to the review at bit-tech.net the performance is not that good.

    Gary when can I aspect the review about these boards? Or which of these two board would you advice?

    Hi Gary,

    Great article! Looking at other user's experience w/ the Gigabyte board, I've seen a number of complaints w/ memory compatibility (e.g., Newegg's reviews). Would you mind posting the part #'s of the different memories you tested this board with?

    I did see your comment that the F4 BIOS improved memory compatibility, but to my knowledge they haven't updated their qualified memory list yet.

    Also, if other users on this forum have experience w/ this board, would you mind posting your memory config as well?

    Thanks!
  • Awnold - Friday, October 9, 2009 - link

    I'm mostly curious about the G.Skill memory used. Does anyone have any success (or BSODs/failures) with the following modules:

    F3-12800CL7D-4GBRH
    F3-15000CL9D-4GBRH
    F3-16000CL9D-4GBRH

    stop with this P55 flood and finaly review a few 785G boards !!! please please PLEASE !!!

    I don't care about intel, I want to build an AMD PC and your site is severely lacking in that part ...
