SLI: 750i vs 780i

[Tatty_Two]

The only trouble with both board is they will not support the 1600 Fsb 45nm chips 9770 etc.

BIOS update? works for most boards...think 965's and 1333FSB however in this case you may well be right but would you want it to? isnt 1600FSB chips/boards specifically designed for ONLY DDR3???

not sure but msi says they don't work on there web site for these boards.

All I know is I want one of those Asus P5N-D's!

I have been running my MSI 750i stable for a month now with a x6800 at 3.4.
I just ordered a Q9450 from tankguys and will report back on how well it overclocks.
Should get the Q9450 by the end of this week.

The reviews suggest that your better option would be the MSI 750i Platinum.

That would be good thanks, I am ordering one tonight, I ordered it yesterday (well I thought I did) but for some reason it didnt happen!

Yup, thats because the board is DDR2, 1600FSB boards will be ONLY DDR3 I beleive.

I've been coming to the same conclusion, but I'm looking at buying the ASUS just because it's so much cheaper. At least here in Japan, the MSI is only about 10USD less than a 780i board!

Would I be committing a massive mistake if I buy the ASUS?

IDK to be honest but I cannot beleive that there is so little difference in price (not questioning you, just surprised), in the UK the difference is £70 thats $140!!! remember there are to models, exactly the same but the "Zilent" is more expensive because it comes with the Zalman CPU cooler, the other model is a fair bit cheaper here without the CPU cooler.

Yeah I realize that, but it doesn't seem to be that particular model. There was nothing about "Zilent" and no indication of a CPU cooler--yet the price tag is about $290 at every store I look at. An XFX 780i is a little over $300. Meanwhile, the ASUS is going for closer to $230--which still seems to be over-priced, but I think that's generally the way things are for a lot of parts here...

I really thank you Tatty! That MSI board does look like it would fit the bill better, and help with some futureproofing. 2 PCIe's versus 3 on the MSI, 2 IDE's versus 1 on the Asus. I like it alot.

Your welcome, I have done a fair bit of research on both the 780i and the 750i boards and it seems that with each chipset the MSI Diamond (780i) and Platinum (750I) are the best of the bunch, for overclocking, cooling, stability and features. Currently, unless you want to go tri SLi there is not really any reason to get the 780i over the 750i as on the MSI boards the other features, phases and capacitators are the same. Of course the 780i boards are 16 x 16 as opposed to 8 x 8 on the 750i but that makes no difference on current cards with PCI-E 2.0 enabled motherboards.

Just an FYI guys, I do have a brand new MSI 750i Platinum for sale if anyone is interested.

I was thinkin the same thing about these 2 motherboards, but I want to run my E6750 at 2000Mhz FSB and 4Ghz do you think the 750i can handle it?

Probably not this early in it's life TBH, from reviews and other forums owners seem to be getting between 470 and 490FSB but everyone seems to expect with the next BIOS release it will probably go to 500mhz but the board is young and most have to develop a little through BIOS updates, what is fairly certain though from my research is that the MSI 750i overclocks better than the MSI 780i and the MSI 780i seems to overclock better than any of the other 780i boards so by getting one you would be pretty much assured of getting the most out of an SLi board IMO, you should certainly get more out of it (E6750) than you are at the moment and as the MSI board is cheaper than your current board, with a bit of decent ebaying it shouldnt cost you anything.....just my thoughts.

no both have a max of FSB of about 475 FSB

If the 780i boards are not an option, you might want to consider the new SLI boards from ASRock. The Penryn1600SLIX3-WiFi is a 680i board they're just about to release. It has pretty amazing specs, so don't scoff yet

• FSB up to 1600MHz
• Supports all 775 CPUs ( including QX9770 )
• 4 x DDR2 RAM slots (8GB)
• 3-way SLI ( 2 x PCIe 16x, 1 x 8x )

Here's a review on OCWorkbench. They had an E6550 running at 1880MHz FSB (6x469)... not stunning, but not too bad for a budget board... actually, I was just impressed when they didn't say it was crap for overclocking.

If overclocking is a priority, you might want to check the 650i-based Penryn1600SLI-110dB board, instead. As people have said, it might be a better overclocking board. OCW reviewed the Penryn1600SLI-110dB a few weeks back. And these German guys even considered it a very stable übertaktungsfreudiges board, for some reason.

Those ASRock boards are so cheap you could get one and wait for the 790i boards to drop in price, or the 2nd-gen boards to arrive. The Penryn1600SLI costs about $100, and I'd guess the SLIX3 will be around $130-$140. I'm considering that option because the 790i boards are over £220 here, and the 1600SLI is £50.
