ECS C19-A SLI nForce4 SLI Intel Edition Motherboard Review

ECS C19-A SLI nForce4 SLI Intel Edition Motherboard Review - PCSTATS
Abstract: The nForce4 SLI XE chipset is destined for the Intel Pentium 4 platform (socket 775), but it has the potential to dish out full nForce4 SLI Intel Edition type performance!

nForce4 SLI XE and ECS = Hardcore Overclocking?

Hello nForce4 SLI XE

The nVIDIA nForce4 SLI XE chipset is built for the Intel platform only, and is essentially the nForce4 SLI Intel Edition minus nVIDIA's ActiveArmor Secure Networking Engine. It is paired with the nVidia MCP51 Southbridge in this case. The rest of the features are between the two chipsets are nearly identical; 20 PCI Express lanes (16 of which are devoted to the videocards), nVIDIA DualDDR2 support, Serial ATA II support as well as RAID 5 support.

The nForce4 SLI XE also supports nVIDIA's ActiveArmor Firewall, native Gigabit Ethernet and nTune.

Experts Tip: A Fix For SLI Troubles

nVIDIA's SLI technology generally works flawlessly, but sometimes it's not enabled even though the drivers say it is. After a lot of frustration, we've found that the fix is rather easy. It seems the problem lays with the motherboard driver instead of the videocard, but both need to be removed completely. Simply uninstall the driver via the Add/Remove option and reinstall the motherboard drivers, followed by the videocard drivers. That order of installation seems to resolve the SLI not functioning issue in most circumstances.

Overclocking the CPU and Memory
Overclocking the Videocard

ECS and overclocking have not historically gone well together... but that reputation is definitely starting to change. The companies latest retail motherboards have been pretty good overclockers on the whole, and it will be interesting to see if this trend is continued with the ECS C19-A SLI motherboard we're evaluating in this review.

First things first, before we start to overclock the C19-A SLI we'll need to lower the memory frequency down to 533 MHz mode, this way the memory will not hold the system back.

Starting at 200 MHz FSB, we began overclocking in 5 MHz intervals. The ECS C19-A SLI motherboard handled these increases smoothly, and there weren't any bottlenecks until 230 MHz. To achieve higher speeds the processor voltage had to be increased to 1.45V, otherwise the system would crash while loading Windows XP.

At 240 MHz, the system hit another blip and again it was the processor that was the limiting factor. This time voltage had to be increased to 1.5V. Eventually the system maxed out at 250 MHz FSB, although I have a suspicion that it's the retail Pentium D 840 processor which is giving out first and not necessarily the motherboard.

Overall, 250MHz FSB is a pretty nice overclock from a budget motherboard like the ECS C19-A SLI!


Inside the ECS BIOS there are a fair amount of options to fiddle with, however the only one's likely to be of interest to enthusiasts and tweakers are shown below.

nVIDIA nForce4 SLI Intel Edition motherboards list the motherboard clock speed as the processor bus speed, to figure out the FSB you'll need to divide that value by four. The motherboard can be adjusted in 1 MHz intervals between 800-1300 MHz (200-325 MHz FSB) and the memory can be independently adjusted between 400-1300 MHz (100-325 MHz). In the Performance Options section, users will also find some memory timing adjustments.

ECS only includes the basic memory tweaks but that should be enough for the entry level user. CPU voltage goes as high as 1.6V and memory up to 2.2V.

Prelude to Benchmarks

The details of how the ECS C19-A SLI motherboard test system was configured for benchmarking, including the specific hardware, software drivers, operating system and benchmark versions are indicated below. In the second column are the general specs for the reference platforms this nVidia NForce4 SLI XE Intel Edition system is to be compared against. Please take a moment to look over PCSTATS test system configurations before moving on to the individual benchmark results.
