PCIE-3.0 on any Main Board?

[DwarfAdigginAhole]

Ok so from what I understand, Any of the Z68's can be upgraded with a bios upgrade to have PCIE 3.0 bandwidth. If all this upgrade is, is an overclock of the NF200 chip, then would it not be possible to modify even an AM3+ MOBO to run PCIE 3.0 bandwidth? I have no Idea really but, it was just an odd thought I had on the mater XD

Possibly, we would just have to wait.

I think it's stupid to begin with. from what i understand we haven't even nicked PCI 2.0 yet. I don't think it's anything to concern yourself with, if you are concerned.

if what you are saying is true, the Z68 has BIOS-locked PCIE3.0 buses and can be unlocked via an update.

this doesn't sound correct to me. (but, what do i know!!!)

It is not about being concerned with, it is simply about the possibility of it being achieved on any main board, and it is a very unique thing in IMO

I mean, now we don't have to fret over having lanes split into 16x/8x because a 3.0 8x runs the same as the current 2.0 16x's

The MSI Z68A-GD80 G3 has 2 of them.

Actually that has already been confirmed, all the Z68's can have 3.0 bandwidth and will be available with the next BIOS update with them

i was under the impression that the Z68/69 PCIE3.0 controller was ON the ivy bridge CPU itself

Yea, I do believe it said something along the lines of that you also had to have a supported CPU or something to that effect...I think

the CPU and BIOS are two different things... the BIOS is an EPROM that can be written to (flashed).

so with the question in the OP, "can an AM3+ be modified to run PCIE3 ?". the answer is NO

whitch is a socket 1155 so no the pcie 3.0 controller is not on the ivy bridge as you can see you can use it with sandy bridge.

z68 with pcie 3.0 32gb/s double that of a pcie 2.0

Not necessarily, I was unsure about that whole CPU thing but, IT HAS BEEN STATED! that the Bios is what would be changed so PCIE-3.0 could be ran on the older Z68 so, in turn there could be a few possible ways to run PCIE-3.0 on AM3+ if the Bios is the issue. One more note, you are being very confrontational and seem to have an attitude that I really do not appreciate. Please loose the "in your face" kind of attitude :|

i thought they trying to say that these mobo are capable of running PCIE3 cards but will downgrade to Gen2

@diggy: i do not mean to come over that way... before answering your question i searched many forums and sites for the info before i replied, as i was unsure...... then i answered your original question!!!! i am sorry if i offended you

the pci-e lanes are controlled by the cpu thru the z68 chipset so if'n ya had the cpu that supported the pci-e 3.0 I.E. Ivy Bridge cpu then to run that cpu on a z68 board yes you'd have to flash the bios to support it thereby having pci-e 3.0 support off the CPU so its a yes and no lol. you have to have both for it to work. Its just not a flash to support pci-e 3.0 but Ivy Bridge. Just like ya had to flash the bios on AMD to support Hex core cpu's.So its not a flash of the NF200 chip so therefore no it will not be supported on AM3+ unless it has pci-e support on CPU as well.

Hope this explained it better for you.

What I don't understand is why does it matter? I understand what diggy is saying of it being cool and all, but what propose does it serve? Personally i think (i am almost 100% sure) it's a selling gimmik, so Intel can make even more money. from what i have seen i have not seen anything that will use PCI 2.0 fully and will not see anything that does for at least 3 more years AT LEAST. If i'm wrong please show me a URL of something that fully utilized PCI 2.0 x16.

...show me a URL of something that fully utilized PCI 2.0 x16.

AFAIK the only hardware that could fully utilise the PCIE2.0 are NVIDIA Tesla C2050 or C2070 GPU cards.

but, as of now, no-one has written any CUDA software that would use all of the bandwidth at-one-time.

Copy pasted form another thread I posted it in.

I saw this earlier I didn't think you would need a BIOS update but apparently you do, also you don't even need a gen 3 mobo for PCI-E 3.0 acording to what Gigabyte are saying

http://www.gigabyte.com/press-center/news-page.aspx?nid=1048

"GIGABYTE Announces Entire 6 Series Ready to Support Native PCIe Gen. 3."

I did read in a thread on Aria though that

"Basically every board that doesn't have PCI-E switches or an NF200 chip is already PCI-E 3 compatible."

http://forums.aria.co.uk/showthread.php?t=71145

So there isn't even a need for a Gen 3 mobo apart from the fact that PCI-E 3.0 will be native on them. The BIOS update is to basically overclock the PCI-E chip to run at PCI-E 3.0 specifications.

So whether your mobo runs PCI-E 3 natively or not it doesn't really matter because it will work both ways anyway.

Also the PCI-E controller is on the CPU but the PCI-E chip is on the motherboard. Even if you do the BIOS update to make your motherboard PCI-E 3 you won't be able to use anything PCI-E 3 because Sand Bridge CPUs only have a PCI-E 2 controller so in order to use PCI-E 3 you will need a Ivy Bridge CPU.

All 1155 motherboards will be Ivy Bridge compatible because just like Sandy they are 1155 socket the only thing is unless you can update your motherboard with the PCI-E 3 BIOS then obviously you wont get any of the benefits, if there is any at all of PCI-E 3.

All Gen 3 mobos that are starting to come out now like the Asrock Fatality Gen 3 and the G1 Killer - Sniper 2 will run PCI-E 3 natively.

What this means for AMD and PCI-E 3 I have no idea because I know nothing about their CPU's.

thank you for clarifying my point

Have Asus released any similar info for their Sandy boards, ie whether they have/are releasing such a bios?
