Asrock Fatality Pro PCIE Speed Lane

The Penguin · Feb 5, 2013, 01:33 AM

Hello everyone!

My very first post!

My question is in regards of this particular mobo, to be more precise, the PCIE ports.

http://www.asrock.com/mb/Intel/Fatal...0Professional/

This Mobo brings only 2 PCIE X1- The very first one is almost unusable due to the cpu heatsink.

The 2nd PCIE X1 is not much help because the current gpu im planing to install will partially occupy the PCIE X1 slot.

Is use a dedicateed sound card on a PCIE X1 slot, therefore i need one of those 2 slot free, however there is one PCIE X16 slot on the bottom of the mobo.

Do you reckon i could install the sound card on a PCIE X16 slot?
And if so, would that slow down the PCIE speed lane of the main gpu from x16 to x8?

Hope it makes sense

Thank you

!

It depends on what you have for a graphics card, but in most cases running 8 lanes instead of 16 shows negligible loss.

Use the x16 slot at the very bottom, it won't affect your graphics card (which is tied to the other x16 slot)

As per the manual says that one gpu on the PCIE X16 (The very first one) it will run at 16x, if xfire-sli will run at 8x, the last PCIE x16 runs at 4x.

Thanks!

Nice to know!

Will the sound card work on a PCIE X16 slot, when it's suppose to work on PCIE X1 Slot?

Yes it should fit fine. FYI- the bottom slot is only X4 anyway (according to your board specs)

and Welcome to TPU

Yes, it will work. You can put an x1, x4 or x8 card in an x16 slot and it will work perfectly. The bottom slot in this case is physically an x16 slot but wired as an x4 slot, and it doesn't affect the two other physical x16 PCIe slots.

Excellent!!!

Just another question:

If you had a Samsung 840 series pro 256gb (brand new) and you are about to install a new gpu on a gaming rigg, would you swap the current ssd (a samsung 830 256gb) for the brand new ssd?

That being said, i would need to install windows 7 from scratch.

The other option is keep using the current ssd 830 series and uninstall all the old drivers From my old 6850 amd series and hope for the best.

Thanks to all for their fast response!

Just to not double post. Please try to use the multi-quote button when quoting multiple people and the edit button if no one has posted after you yet. It's against the forum rules and is a good practice to try and avoid.

...and no, I wouldn't. The 840 isn't that much faster than the 830, but that's really up to you.

My apologies, i was not aware of the rules.

I have read that the 840 pro is actually bit more faster than the 830..

Definitely think that the performance is within 5-10% of that of the 830. I would place that within margin of error. I've also heard issues with reliability on the 840 vs the 830, but I'm not sure if most of those claims are valid or not. Either way, both SSDs will perform about the same.

Just curious what graphics card you're using that's going to take up three slots.

You're right. I thought the PCI-E 1x slot was the second one in. Your card is 3 slots wide? What is it? An Asus DirectCU? Either way, one of those 1x slots normally should be available. I find it very odd that your CPU cooler is blocking the first one as well. I have some pretty big CPU coolers and they don't cover any of the first slots.
