Test Setup

The Intel 975X chipset fully supports the 820, 830, and 840 dual core Pentium D processors in both stock and overclocked conditions. This chipset also supports the upcoming Presler and Cedar Mill processor range. Dual core really makes a difference in certain multi-tasking scenarios, as was demonstrated in the dual core performance preview. If you are interested in how the various chipsets perform in a real world multitasking setup, please take another look at that review.

NVIDIA SLI Performance

The 975X chipset is able to support NVIDIA SLI technology with a specially configured and non-certified 78.01 driver along with proper bios support. However, NVIDIA has not sanctioned or licensed their SLI technology on the Intel platform.

NVIDIA SLI Performance

We have included ATI CrossFire results in these tests to indicate the ability of the X850 CrossFire Edition to operate on an Intel 975X platform. The X850 CrossFire solution is not competitive with the current NVIDIA 7800GTX SLI offerings. We did not witness any issues with the ATI CrossFire setup while testing the Intel 975X boards. We look forward to the X1800 CrossFire Edition cards as performance should be on par with the current Nvidia 7800GTX 256mb offerings.

Although the performance does not match the newer 81.xx series of drivers, the 975X boards are still competitive with the nForce4 Intel Edition SLI setup considering the beta condition of the non-certified drivers used. We noticed some graphic anomalies with the Asus P5WDG2-WS in the benchmarks that explains the lower scores compared to the Gigabyte board.

The ability of the 975X based boards to run both ATI CrossFire and NVIDIA SLI setups is definitely a marketing plus, but until Intel licenses and NVIDIA fully certifies and sanctions SLI on the Intel platform, we can only wonder what the impact would be in the market.

Overclocking Performance

The overclocking performance graphs have been added to the standard benchmark test suite and should allow for a better comparison on the overclocking capabilities of tested boards. For more details on the specific overclocking abilities of this board, please refer to the Overclocking and Memory Stress Test section in the Basic Features section.

Overclocking

Overclocking

The front side bus overclocking results were impressive for the Intel 975X boards and exceeded those of the Asus P5N32-SLI with the Smithfield based processor. We will see how well the nForce4 based P5N32-SLI does with the Presler and Cedar Mill processors in our next article.

    obviously you have never tried to run a data center

    So data centers are built with floppies, COM mice and LPT printers. Great! Very nice that I don't run one, thank you for enlightening me.

    or ever bought hardware on a budget

    FYI I've got ABIT AT7 mobo (the _ONLY_ legacy free mobo ever created) very cheap a couple of years ago and it was running all my 4-5 year old hardware like cheap USB kbd and old second hand USB mouse. And I still DON'T even consider wasting my money on Athlon 64 or any fancy PCIe stuff, and with all this I still sound Bleeding Edge Hardware Freak for you? Are you from a PC museum or what? Can you even find COM mice these days? I'm not buying anything that's above lower 30% of price range, so I won't even consider mainstream stuff these days. You seriously overestimate my financial abilities and more important my will to upgrade (I won't fix my PC unless it's broken)

    nor that you run windows..

    XP SP2 here :P
    quote:

    or are you conviently forgetting that Windows has the worst in-box hardware support available and that to run many SATA drives requires installing drivers as though they are SCISI devices rather than on-chip devices.

    I'd do that by patching my XP install CD or by using USB floppy (if it works, not sure about this), or if it doesn't work I'd replace my boot HDD with PATA one, given that it's not any slower than SATA these days :P So floppy is still not necessary WHILE every mobo out there includes PATA, and please note that I didn't include PATA in my Stupid Obsolete Interfaces list :) PATA is obsolete, yes, but it's still widely used everywhere (in almost every DVD burner, jeez, that's what I call LONGEVITY!) unlike LPT and COM and floppy and other museum stuff.

    Or that not everybody can afford to upgrade to a new laser jet / ink jet / Hp OfficeJet at every new release, and that for many a business the stock dot matrix offers the best price/performance and there is no reason to replace a perfectly functioning dot/matrix printer for something that costs a lot more to run.

    I'd say stick those LPT plugs onto the cheap "business" mobos, but please let us breathe fresher air with the "advanced", overclocker or whatever you call 'em mobos. There is a place for the old mobos with legacy stuff, but including them on those ubercool silver/gold advanced P4 975X or nForce4 SLI Ultra Extra boards? Do you seriously think the guy with dual 7800GTX setup uses COM mouse, LPT printer and other "data center" accessories? Hahahahahaaaa
    quote:

    or that usb support for keyboards is a little spotty in the Microsoft bootloader if you do try to run multiple versions of windows

    Never tried that. I only run XP SP2 and never ever run into issues with its bootloader and my USB kbd, maybe 98/95 one has issues, dunno. Anyway, if you still use 95/98 then ok, you need COM and LPT as well.
    quote:

    Or that many older devices still require the com ports.

    It would be hard to persuade me someone still uses COM mice, their mechanics must be ground into dust by now :) And even if there are some ancient PDAs that don't have USB 1.x then there are USB-COM adapters, so COM is not needed too (btw there are USB-LPT adapters as well, for your data centers :P)
    quote:

    Sure, if you are building a brand new computer and have no hardware you ever intend to run again, running a legacy free system is a good idea. But, when you only have 5% of the market at best... it just doesn't make sense.


    New computers are only 5% of the market? All these Dells, Compacs, HPs and many more, they are only 5%? OK, so 95% of the market are what? Retrofitted IBM PC XTs? Hahahahaaa...
    quote:

    Sorry, but I find the laughter and your comments to be so far off base... I can only sigh and wish I had your budget to spend.

    Man you have no idea about my budget, really really! I run ABIT KW7, and looks like Socket A is my choice for at least 12 months from now if not more, depending on how things will turn out with Vista. You wanna know my top list of mobos I'd buy right now if I had the money? Number one - Chaintech S1689, dirt cheap 939 mobo, only 50 bucks or so, just stick cheapest Venice 3000 in there and fly away. Number two - ABIT AN8-V. Expensive bad boy, whole 80 bucks!... but it's from ABIT and so it's again ALMOST legacy free (damn I hate you floppy and PS/2!) so this one I'd take if I had BIG money to swap my old AGP video with some cheap PCIe 6600GT or somethin'... and you call me a Big Budget Guy. Hahahaaa... can't stop laughing, sorry :)

    OK, if you really insist, I'd agree that legacy stuff has its place in PCs and will have place for many many years to come, but including these 20-year old COM and LPT plugs on the so called "advanced" nForce4 SLI Ultra Extra whatever boards? Hahahahahaaaa.... sorry again, just can't stop laughing...
