Testing Methodology

This is Benchmark Review's fifth article where the Intel i7 series of processor was used. The focus in this review shifts from solely the processor to more that of the motherboard. In our other releases we strictly used the Intel DX58S0 Smackover motherboard with the only comparison being the different processors we tested. Today we'll use a single processor, the Intel i7-965 Extreme Edition and compare its performance using the Intel DX58S0 heads-up versus the ASUS P6T X58 Deluxe Motherboard. In our previous reviews we also compared a previous generation X48 motherboard, the ASUS P5E3 using an overclocked Intel X3350 processor to establish some semblance of comparison to then versus now. To put is mildly, the P5E3 and X3350 were completely outclassed in every arena except for gaming in which the results were a bit closer. For that reason to day we will be comparing only the two X58 motherboards using the fastest processor currently on the planet, mano-a-mano. For those extreme enthusiasts out there we also tested both motherboards using our full array of benchmarks overclocked.

Unfortunately when testing systems of this type there is not set of "grass roots" tests that will completely speak to the to the system's overall performance. It is therefore necessary to comparatively test the performance of the CPU, Memory, Hard Drive(s) and Graphical Rendering and then draw your assumptions from the results of these tests. We chose an array of benchmarking tools (captioned below) that we felt would give our readers a complete of a picture of each system's performance. Each benchmark test program begins after a system restart, and the very first result for every test will be ignored since it often only caches the test. We then ran each of the tests a minimum of three times and reported an average of each test's results. We ran enabled Turbo Boost on both motherboards with the processors at their stock clock speeds.

# eSATA port not stableGuru 2010-02-28 02:25

Please dont buy this board if you are planning to use eSATA port.

I was using an eSATA volume on my DX58SO for backup using Clonezilla. At first this worked fine, but at some point I started getting I/O errors in the middle of the process. I swapped out various components and tried both ports, but the unreliability persisted. I was speculating that maybe one of the BIOS updates rendered the eSATA ports unstable (it would presumably be BIOS, because Clonezilla isn't running Windows or Windows drivers). Very's interesting to see that someone else cautions against eSATA. Anyway, I don't have a critical need for eSATA, so I've just stopped using it; can substitute USB, albeit with loss of speed. But I'm never comfortable when something isn't working properly; I want to know the full story.

I faced the same problem, with WD MY book (1TB) external Hard disk.
The eSATA port works for first 5 min, and the windows freezes for some time or i used to get PD(or some such) time out warning and newer stops. Initially i suspected about the WD hard disk, when i contacted them, they said there is some problem with marver controller (which is used in DX58SO mother board). so i took this issue with Intel support team, but its of no use..

Tried installing latest BIOS, Marvel driver, Intel Matrix storage drivers which are available in Intel webpage, its of no use.

My intention to buy DX58SO was mainly for using eSATA port for which i had huge data (around 25 Gb) to be used for testing purpose. now because of the one HDD (eSATA) is not working why will i invest on another HDD for which to make sure the problem is not there in Intel Mother board. So i brought low cost PCI-eSATA card (which is 10 $) which is working fine with DX58SO.

Aha! I finally found an official word that maybe clarifies the need for the unusual extra "auxiliary power" connector on the DX58SO. This Intel page indicates that the extra power cable is only necessary when the primary power connector is an old 2x10 connector, but it's not necessary with a newer 2x12 connector. So this is just Intel's way of making the board compatible with older hardware.

"Next generation high-end graphics cards will consume from 75 watts up to 150 watts of power. The PCI Express x16 connector can deliver up to 75 watts. In order to achieve 75W, an ATX12V power supply with a 2x12 main power connector is recommended. However, 75W can also be achieved with ATX12V power supplies with 2x10 main power connector when using the 1x4 power connector on the board."

FYI - Purchased this board in June, 2010. Intel has changed the internal SATA connectors so they plug in from the back, not from the top as noted in the review.

Thank you for the update! Do you happen to know which revision your motherboard is (should be printed), so I can update this article?

Hmm... usually it will be printed on the motherboard itself. For example: R2 or Rev 2.

Where did the name "Smackover" come from? Was it from the town Smackover, Arkansas?

Good question. Intel doesn't say.
