Having 670 GTX PCIe 3.0 & mobo with PCIe 2.0

Haithm · May 17th, 2012, 09:16

I have rushed to buy a 670 GTX without looking first at the PCIe interface of my motherboard. It is PCIe 2.0 and H57 chipset with i7 860 2.80GHz. What should I do? What are my options?

KrossX · May 17th, 2012, 09:20

Put it on the PCIe slot and enjoy it? Sounds like a good idea to me.

What? So PCIe 3.0 simply work with PCIe 2.0 slot? I don't know hhave to do anything than putting the card on the slot? That's it? the case is closed?

KrossX · May 17th, 2012, 09:33

Basically, since it should be backwards compatible.

It's not going to make one difference using it in a PCI Express 2.0 slot. PCI Express 3.0 is redundant right now and more for having it ready ahead of when it's needed. It's always been that way. AGP 2.0, AGP 3.0, PCI Express 1.x, PCI Express 2.0 and 2.x, and now PCI Express 3.0 have all always been totally redundant on release. Do not put a single ounce of weight in whether you have it or not.

Aw, thank you madam. I am a fan of your hugely informative posts on the forum. Most of the time you put no chance for the reader to misunderstand you. The reader know exactly what you want to say and talk about. Thank you very much for putting much of your times into posting and helping others in the forum.

Princess Garnet · May 17th, 2012, 10:29

I'm not free of making error or conveying myself wrong and/or being misunderstood (quite the opposite on both counts if you ask me), but thank you for your appreciation.

Either way, putting it in a PCI Express 2.0 or 2.1 slot won't lose you any of it's potential, so you needn't worry about it. The buses and connectors were always introduced ahead of time from being required in order to be ahead of demand, which is a good thing.

Ah, sure good thing.

Just in case two voices don't put you at ease yet here's a third saying that won't be any sort of problem and everything will work perfectly without any tweaking despite the PCI-e x16 versions differing.

Thank you sir. You guys have made me relax uhh ...
.. and I thought PCIe differings is a big deal or something.

**SCHUMI_4EVER** · May 17th, 2012, 19:51

Well I wouldn't try a PCIe x16 3.0 card on an old 1.0 slot so there is some difference but if there's just one whole number between the versions then there's no problem.

Even then there still won't be a problem, per se, but at that point, you might have some bottlenecking (depending on the CPU and GPU you pair). Any board with a PCI Express v1.x is bound to have a CPU that will also do just that to many higher end PCI Express 3.0 video cards anyway (but should probably be okay with future lower end PCI Express 3.0 GPUs). There are some cases where newer GPUs had some issues in older PCI Express slots, but that wasn't a problem exclusive to the PCI Express itself but rather some specific boards, BIOS, and/or video cards or something.

PCI 3.0 GPU is the same as a PCI 2.0 GPU. No current or planned card fully saturates PCI.E 2.0 to the point where the Gflops hit a wall.

Similar to a CPU using a 64 bit register. There is no need for such extreme ram amounts, and to that effect most 64 bit cpu's do not actually have a 64 bit address bus, There is no need to have that much ram, so most processors are chopped down to 44 or 48 bit, such as the Itanium.

There were issues with some original 1.0 boards supporting the new 2.0 cards so I wouldn't quite say that (it appears mainly on the AMD side). 1.1 to 2.0 was fine however. I guess that could also be linked to some flaw in the AMD chipset though.

I guess it's the same as the AGP era, with some old motherboards having troubles. At least you had the option of going into PCI compatiblity mode back then.

I mentioned that very thing in my final sentence.

Just FYI, PCI express cards that draw more than 75 watts and lack the optional 6/8 pin connector(s) are not compatible with PCI express v1 to v2 slots (the power delivery limit is 75 watts on 16x v1 to v2 slots, 150 watts on 16x v2.1 slots onwards).

The same power output limitation can affect all cards that draw more than 75 watts from the slot, no matter if they have additional power connectors. It depends on the design of the card in that case.

Ah so that's what the issue was, thanks PsyMan.

PCI Express power draw! That was actually my concern from the first place but I didn't mention it! I was really confused when no one mentioned that and I started to doubt about myself.
Thank you very much PsyMan. You own this thread now.
