Computer lagging everywhere after installing EVGA GTX 760

I'm really at a loss of what to do, I've seen other posts of the same thing happening, but their issues are not the same that I have.

After I install the graphics card, the whole computer lags up, even the mouse, and internet.

The power isn't a problem, I've got 850W.

The components I have are in this Newegg wishlist (with a new graphics card obviously, and a new power supply): https://secure.newegg.com/WishList/MySavedWishDetail.aspx?ID=14817948

I would love some advice on where to even get started.

missed your power supply...

the card.......... this is a new card?
.........................what is it?
.........................what was the old?

the heat sinks and fans are clean and clear?

any new thermal paste on the cpu or gpu?

check all internal connections. sometimes messing around will loosen a wire....... might look like it's on but kind of cocked a little.

So, the PSU is EVGA SuperNOVA 850G2 80PLUS.

I don't think it's any of those things. When I take the card out and put in my old XFX GeForce GTX 275 it runs just fine. Then I switch back in the GTX 760 and it lags to hell.

I'm thinking I need to update my BIOS for my Foxconn Renaissance but their website is gone.

I tried all that, those are good ideas but nothing happened. It seems that NVIDIA says there's a possibility of the graphics UEFI BIOS interfering with the BIOS if it's not the latest version. I think my MoBo BIOS is from 2008, and Foxconn's website is down. Do you have any ideas where I could get the newest version?

Hmm, 1.0 as in Renaissance 1.0? Are you saying that if I update the BIOS it should fix all that? Also, how do I test the voltage?

gotta look in the BIOS. too old to remember and don't futz with that old hardware much anymore. guess it's the legacy bios. you have to search through it.

you can reset cmos. if something was out of whack it might help................ but check the pci-e bus for speed and set it. and see if you can find voltages............. you really can't screw things up ............. I shouldn't say that........... but just be aware of what you are doing and look at stuff...... 20times if that's what it takes to familiarize yourself with what's there.

do you still have the booklet or you can look at a pdf on line now I guess.

Well, the booklet says the voltage is monitorable by using a utility called FoxOne, which is not on the original CD, it must be from their site, which is always down.

I also managed to update the BIOS using their own online updating utility. I'm pretty stuck.

Well after messing with this all day, the simple fix was to just remove one of my 2GB sticks of RAM. I have 3x2GB, giving me 6"GB".

For some reason the motherboard isn't mapped properly to deal with that much RAM coming from the graphics card. It's really a BIOS fault, there's absolutely no reason to have this problem. So for now I am truncating the memory in bcdedit to the end of the last address of "write-back" memory, which is at a lower address than the end of the usable memory. using the command.

bcdedit /set truncatememory 6442450944

That is exactly 6GB in bytes.

This is the dumbest problem ever because the board can handle up to 12GB, but this is way beyond my expertise, but is there a way to modify the RAM mapping in the motherboard?

Yeah man I did. There hasn't been an update since 2009, before there were any graphics cards strong enough to screw up the mobos.

I know it should be "possible" to have a bios patch but how? Custom bios?

The tool provided by Foxconn advises against that one. Like I said that company is trash. It says it won't work on 64 bit architecture, is that a thing? Does the BIOS care about that?

I haven't checked it for errors, but the Linux diagnostic tool has confirmed that there's a mismatch of ram maps. There's a whole chunk that's usable, but not cacheable.

Yeah if you "run Ubuntu from a USB" drive you can analyze your memory a lot better than what you can do in windows.

So, dmesg | grep e820 shows usable and unusable and reserved ram.

cat /proc/mtrr shows cacheble and non cacheble memory and they should have the same addresses.
