Hello guys, My motherboard is GA-H97M-D3H. It's got one PCI-E X16, two PCI, and One PCI-E X4. I was searching around the internet and found that there wouldn't be any performance gains if I crossfired using the X16 and X4 lanes, so I searched again if I can possibly split up the PCI-E 16 to make it X8/X8 and came across this product, http://amfeltec.com/products/flexible-x4-pci-express-4-way-splitter-gpu-oriented/.

Has anyone here tried this and confirm that this actually works before I put my money down into anything?

Interesting. I don't know how well that would work out though. If it even works, I'm interested to know how well drivers handle multiple GPUs in one lane. And although it's split, can you even run SLI/CrossFireX on them? Are the lanes configured to run at x8/x8 if two cards are installed? SLI is probably a harder sell because SLI compatibility is more picky so it may not even work.

Also, based on what I read, it doesn't look like it's affordable at $400+. Maybe it's cheaper but I don't see any mentions of it on the site outside of what people posted on forums. At that price, I recommend upgrading the motherboard. It's so much cheaper and more re-assuring.

Thank you for your reply, friend. I was trying to avoid upgrading my motherboard. But if that's the only cheap way to do it, that's what I'll have to do. Having a small form factor computer, it's hard to pick a cheap motherboard with one PCI-E x16 and one PCI-E x4 lol. But I'll look around.

I would request a quote from amfeltec and see what they have to say about it. My guess is that it won't be cheap and can be more trouble than it is worth. It's one thing to pay $400 and it works immediately. But when you pay $400 and it doesn't work because of driver issues or whatever other issues, that can be a huge upset. You will be throwing tantrums!

By the way, the H-series motherboard doesn't pair well with the i7-4770K because you can't overclock it. So upgrading to a Z-series motherboard can support your SLI and allow for overclocking. I am assuming the build is listed in your signature.

You're right. I'll have to do that when I'm home. The work computer I'm using right now doesn't have any mail clients installed.

Really? I saw an article about this. The article said that there was an update that let haswell chips to be overclocked in the H series boards.

You are correct. My apologies. Too many things on my mind from other threads. Again, my sincere apologies for the confusion.

As for a motherboard suggestion - Gigabyte GA-Z97X-Gaming 3. Unfortunately, no H-model motherboard supports SLI at this time.

No, some companies are allowing overclocking of the Haswell based 20th anniversary Pentium chip, not the i7-4770k. Get a Z87 or Z97 board if you want to OC, and these should give you better PCI-E options as well :)

EDIT: I may be wrong, time to research!

EDIT 2: As far as I can tell, only ASUS is adding OC functionality to their non-Z haswell boards (http://www.tomshardware.com/news/asus-overclocking-h87-h97-b85,27076.html) I can't find anything in terms of gigabyte boards. They're also doing this without the permission of Intel which is a little naughty lol, tbh I can't imagine OCing would be great anyway on these boards

You're right my friend. Although, when I bought the motherboard, the board came with a disk that has a software that overclocked haswell chips, I don't think that they'd do that if intel didn't allow any motherboards other than Z87 or Z97 overclock the chip, right? I dunno O.O lol

Well I have a crappy H61 motherboard and in the BIOS there's an option for ASUS's O.C. profiles which doesn't even work, but it's there. I wouldn't count on your motherboard being able to overclock an i7-4770k anyway, even if it could I doubt you'd get anything over a .5 GHz overclock (or 100MHz over the turbo clock). If you want to overclock and was thinking about sli then get the board ksham suggested :)

EDIT: In terms of the OC software, it's probably just there in case Gigabyte can get OC'ing to work on that board, I'd definitely suggest an upgrade though for OC'ing and sli

I was able to overclock it to 4.8 haha. But since I don't have a VERY good CPU cooler, I toned it down to 4.1 Mhz. My full load on this clock is like 70-75, my idle is 29-38. When playing Skyrim, it's always on 50-55. I might upgrade to Z97 if I have to get a new motherboard.

Believe me, it also works on Gigabytes H97!

Fair enough, looks like Gigabyte are bending intel's rules a bit lol :p Anyway for sli you'd definitely be better off with a new motherboard instead of that splitter, the splitter won't be sli certified anyway

Yeah I kinda figured I would be needing a new motherboard better than this motherboard I have right now. Which would you recommend for a small form factor build?
