Second Graphics Card Not Always Detected.

[Benedict Monro]

Well I tried this in the Motherboard section, I may have better luck here?

Okay, I'm at your mercy dear users so please help! firstly I'd just like to say hi! To everyone here, I've lurked about this site for a while and it's been a fantastic resource in aiding me throughout my various PC troubleshooting problems. I'm fairly new to PC building and well I'd have lost all hope had it not been to you fella's!

alas I present a problem I've been unable to find an answer for yet, so please help!?

I have one of these https://uk.msi.com/product/mb/Z87GD65_GAMING.html#overview

and two of these http://www.evga.com/Products/Product.aspx?pn=02G-P4-2765-KR

However my Motherboard appears to be frustratingly choosey as to when It want's to detect both, preferring to only detect one, especially when I cold boot.

I've tried all variations of PCIE Slots and Cards and One card in one slot works perfectly! Two however in SLI..... not so much

Would anybody have a solution to my problem?

My full build is

Windows 7 Home Premium 64-bit SP1

Intel Core i5 4670 @ 3,40hz
16GB DDR3 @66MHz
MSI Z87 - G45 Gaming (MS - 7821)

PSU 850W EVO Labs Cronus

I would check to see if your BIOS is the newest available and if not update to the newest.
Also, make certain the SLI bridge is properly connected to both cards.
If that doesn't work, you would be well off to contact MSI as the board may be defective. They may also know of this problem and how to correct it.
Make sure your cards are installed in the topmost and middle PCI-Ex slots. These are the two that will run at X8 in SLI.
