I know DDR3 is faster and..

On LGA775 - no.

SLI support is limited and some games can have noticeable jerkiness. Boils down to what you want to play.

if you want sli on a lga 775, you'll need an nvidia sli board. i've got a couple and they work well in dual and triple sli.

Nah, you don't need it. Modified Nvidia drivers exist.

Sure hacked drivers exist . .they are terrible but I mean if thats your thing then I guess.

I've tried the modded SLI stuff even from Phil's site on a Rampage X48 and it works to a point but I cannot recommend going that route, the system in general wasn't very stable under SLI and eventually I switched to a Striker II board which works beautifully and doesnt require hacky driver work arounds. (the 790i Ultra Chipset is fun to use)

One thing I did note was that Vista32 was far more stable with the modified X48 SLI than XP ever was, XP just didn't agree with the mods no matter what method I used.

This is just my 2cents, it was a frustrating experience but pretty cool when it was stable enough to see games using SLI on a X48 board.

I hope you realize "SLI certified" is just Nvidia driver checking PCI ID of the northbridge, right?

As for the 775 CPU anything with two cores overclocked to 4GHz will be sweet, alternatively 4 core Xeon with 'LGA 771 to 775' sticker and small mod to CPU socket.
Pre modded 775 E5450 will run you $21 free shipping instead of >$80 QX9650. Same CPU in different package.

Have you tried to get SLI running on X48 under XP ?

Like I said it works with the hacky workarounds to let SLI function on X48, YMMV with regards to both stability and usability .. it also doesnt let you use TRI/Quad SLI with dual GPU cards or any card above GTX600 series in SLI under XP unless you also use modded drivers.

If it was as simple as drivers checking the ID of the northbridge then there wouldn't have been a need for the SLI hacks under XP.

But it is, because X58 works flawlessly without any "Nvidia certified magic" under the hood. Nvidia deliberately limited support to sell their chipsets.

You do realise thats because Intel and nVidia worked their shit out and X58 had SLI support right from the start, nVidia pulling out of the chipset market meant they really had no choice but to work with Intel.

None of the Intel based 775 chipsets ever had native SLI because nVidia wouldn't licence it to anyone Why? .. they had their own chipsets to sell, thus if you wanted SLI on Intel chipsets you had to use hacked Russian SLI fixes, there are three of them two from the same programmer, none of them are simple Chipset ID fixes.

Again if it really was as simple as you suggest then all you would have required was fixed drivers, the fixed drivers were all you actually required to get Quad/Tipple SLI on XP with Dual GPU cards and SLI on any card above GTX600 series.

Not even sure how X58 came into this as its not even related to 775 chipsets.

Except that triple and quad SLI is not supported by WIndows XP.

Yes, not supported officially on any chipset. So?

SLI also was "magically" supported by AMD 990FX after the fact, which is just a rebranded 890FX (no official SLI support) anyway. But cool story.

Not even sure how X58 came into this

Unofficial SLI support was improved exactly after X58 release - https://www.overclock.net/threads/howto-sli-o … released.670810.

"In the case of Intel X58 motherboards, checking SLI support by driver was developed with a simplified scheme, which uses text strings and identifiers for all present and future X58-boards. Later P55 are also was added to support similar SLI certification procedure."

"We don't give any 100% guarantee, but as far almost all motherboards which have two PCI-Express slots can do SLI. Only correct ID reports to videodriver and physical ability to drive all videocards from single hub/complex is necessary to make SLI technology enabled."

Anyway, it works.
