Features-

There are not too many bells and whistles on the EVGA X58 SLI from a hardware feature viewpoint and considering the market for this board, we think it is a good choice. The almost universal Realtek RTL-8111C PCIe Gigabit Ethernet controllers are utilized in tandem, the Realtek ALC-889 is on board for HD audio, JMicron’s JMB362/363 chipsets are tabbed for eSATA, IDE, and additional SATA port duties. TI is selected for IEEE 1394a and the Intel ICH10R is utilized for primary storage purposes. We have never been real big fans of either Realtek or JMicron, but considering the dearth of competition in the on-board peripheral market, you make do with the provided choices.

The BIOS is designed to get the most out of the board when overclocking. At first glance, some of the available options like the number of memory timing options seem sparse compared to the ASUS and Gigabyte offerings. However, EVGA does a very good job of setting sub-timings to optimal points so far in our testing. We still prefer the ability to set additional memory timings and skew levels ourselves, but we can certainly live with the decisions made by the BIOS, although those at the bleeding edge of benchmarking would probably prefer the additional control level in either the ASUS or Gigabyte products.

In a nod to the users who like to cool their systems via cascade or LN2, EVGA provides two different modes to properly set the board at POST for sub-zero temperatures. Those who love or need voltages to improve clock speeds will not have any problems with the choices provided by EVGA. DRAM voltages sky rocket up to 3.075V and VCore goes to a nice silicon melting 2.3000V. VDroop control can be enabled or disabled.

Also, you can fine tune the frequency level on the digital PWMs. We normally left it at 800KHz to help reduce temperatures in the CPU area but switched 1067KHz when overclocking our i920 past 4GHz. We were able to get an additional 80MHz out of our CPU on air by switching from 800 to 1067 once we passed 4GHz. EVGA also provides a setting called a dummy overclock, quite simply, enable this setting and the board will set itself to run a 20x160 overclock on the i920. We found the settings to be perfectly stable in our initial benchmarks.

EVGA also supports a stock 1333MHz memory speed on the i920/i940 processors along with opening up QPI link speeds from a standard 4.800 GT/s up to 6.400 GT/s, which is standard on the i965 Extreme processor. We were disappointed with the lack of OC profiles in the initial BIOS, but a BIOS update today allows a total of eight profiles to be saved. Other problems raised in our blog preview have also been solved as of today with BIOS IX58SZ13. We are at the point in testing now that we have moved past bug finding and resolution to fine tuning our settings for performance oriented results.

Finally, the board fully supports 12GB of DDR3 memory. We have not had any real problems running 12GB of our Corsair, Patriot, or GSkill DDR3-1600 kits up to 1600 at 8-8-8-24 1T timings, although we needed about 1.70V for absolute stability. Dropping the command rate to 2T allows 1.65V operation with the current BIOS. Psssttt… keeping CPU VTT voltage in proper sync with VDimm along with the right level of VCore and that nasty 1.65V VDimm guidance can go away, although the blue suits still say it is a potential warranty buster.

One last item of note, at least in this first look, is that the three PCI Express 2.0 x16 slots will operate in x16/x16 mode for 2x SLI/CF if the third x16 slot is empty. If you decide to place a PCIe RAID, network, audio, or TV tuner card in the third x16 slot, then the 2x SLI/CF configuration will operate in x16/x8 mode. We did not notice any performance differences between the two modes with our HD 4870 or GTX 260 cards. 3x SLI/CF configurations will run in x16/x8/x8 mode. You can also use the first and third x16 slots for graphics if you need to open up a PCI slot but the board will run in x16/x8 mode.  Although the owner’s manual states the three x16 slots are for graphics cards only, we had no problems running our ASUS Xonar D2X or Highpoint Rocket RAID cards in x16 slot two or three.

    I think MSI is the only one I've seen so far that supports 24G -- and they are supporting it on the "budget" Platinum board too -- so you can get into the game for ~ $220 -- I frankly see little difference in the specs of the Platinum compared to all the other high-end boards. Reply

    For $329, I'd be expecting an Intel/Broadcom/Marvell ethernet chip, not Realtek junk. Reply

    "For $329, I'd be expecting an Intel/Broadcom/Marvell ethernet chip, not Realtek junk." LOL... I wish the manufacturers would utilize the Intel solution for networking. Also, I get just as many anti-Marvell emails as I do Realtek. ;) I am not that happy with either one right now although the last Marvell driver updates actually made a difference in Vista. Reply

    Lordy, me too...but hardly any of them do. Why, oh why?!

    On low-end boards, if it's for penny-saving reasons, I'd
    understand it but on i975, x38, X48 & now X58 ??? - It's
    practically Intel mobos only...oh, and Supermicro, which
    are superb but about as overclockable as my cat.

    Isn't it sad that your CPU and GPU combined can cost less than your motherboard? Reply
  • strikeback03 - Wednesday, November 19, 2008 - link

    Well, not on this motherboard at the moment, unless you can find a GPU for about $10.

    On LGA775 boards over $300, very possible.

    Hey, seems like you guys haven't made a Buy Guide update in a looooooooooong time. Would be nice for those of us that aren't able to follow all the news and reviews to get a good sense of the parts to buy. Though sometimes sorting on newegg by review count helps too :) Reply

    I have created a motherboard/memory/storage recommendation for i7, IGP, and midrange Intel/AMD platforms for one of several guides coming. Email me if you need a recommendation now. Wes, Eddie, and Jarred are working on finalizing two or three guides right now. Reply

    ty for the review.

    did you mean to say X48 in your last paragraph when comparing it to the x58?

    No, he's saying that you're going to get similar results with an X58 board regardless of manufacturer. Reply
