post #1581 of 3181
did you guys try out xfast ram? Ive been thinking about copying dota onto my RAM, would to loading times increase by a lot compared to a 830 ssd? Ive read that it could leave files on the ram that somehow cant be removed....

I should have stated that I was reading straight from my manual that it is a PCIe 2.0 x16 slot. So I would think nvidia cards would work fine in it.

I found it interesting they were using this special name for what has been around for a long time: a RAM disk.

But... it does make it very convenient because it will configure to move your pagefile there, temp folder, IE temp files, and such. So, it's really convenient. I wish it would work with Chrome, too. But you can configure Chrome to use it, you have to do registry and shortcut editing to make it work because you have to modify Chrome's command line.

When the computer is shut off everything on the ramdisk is gone, so it's only useful for storage of temporary files.

I'm using it. I also configured Chrome to use it. I haven't done any performance tests, though I do think Chrome responds faster in some situations. I disabled the pagefile though, since I have 16 GB RAM, so that part doesn't matter for me.

Ok, but it's STILL only x4, so it won't. Seriously.

I didn't read that page kgtuning scanned in, I was just reading the label which says x16. Why is it labeled an x16 slot if it then says "is used for PCI Express x4 lane width graphics cards". Confusing. Oh, is the x16 referring to the physical size of the slot, but it will only run it at x4 speeds?

It also recommends installing a single card in the top slot. I have mine in the middle slot since I thought it would fit better and be better for case air flow. I wonder if it makes much difference.

If the slot is labelled anything but pcie2, you're going to get reduced performance for a single card setup.

Yes, they're x16 slots but each one is wired differently - z77 does not have enough pci-e lanes to support 3 cards in x16 mode. So you can either x16/0/0, x8/x8/0 or x8/x8/x4 (or maybe it's x8/x4/x4, can't remember). But you can't use the x4 slot with nVidia GPUs, they wont work. AMD only.

That is a x16 slot so you're good with the card there

Hmm... Not according to GPU-Z, see the first image below.
this is while the little render side window is running so there is a load. Bus Interface shows it's only running x8. One of these days, I'll move it up to the top slot and confirm that it shows x16 at that point.

This matches with what the manual said--that this is for SLI situations. So, they really meant that single cards go on top, two use top two, and only in a 3 card crossfire setup would you want to use the bottom one.

CONFIRMED: The second image shows it when it's in the top slot and now it is running at x16.

Yeah...that's my bad. I just re-read the specs and I read it wrong the first time.
