Is my 660ti toasted

mmedeiro · Sep 8, 2013

Hi,

Built a machine for htpc/gaming. 2 660ti in sli, i5 2500, corsair 750tx, ballistix 1600 ram 16gb, Asus mobo.

Everything was running well but I didn't like the fan noise coming from the evga card so I fitted a artic custom cooler. Now the card is crashing in windows when attempting to sli. When I run it in a single 1 card slot I get green lines at the bios screen and windows freezes upon entering my password. I removed the card to inspect closer and I notice the pins on the hdmi slot have bent. I also noticed the board was flexed slightly. Anyway how can I tell if I fried the board?

If you fry it should smell i would think

Can't smell anything. Possible short from the ram glue? If the board flexes too much under hear will the gpu lift off the board on the corners? Has to be something I tried all software resolutions to no avail.

Yes, if it flexes too much and heats up, when it cools, the small components such as resistors and capacitors can move away from the contact points on the PCB. This is what they make backplates for. Did you remove the new cooler and try it? Or at least try to loosen it?

Pretty sure that was the issue. I left the back plate off. Looks like I ruined the card. Sucks. Directions were horrible.

Also; could the legs in the hdmi input short the card? Or is that unlikely?

Is it a fairly new card, still within the retailer's RMA time period? You could ask for a replacement.

If it is only the HDMI port then it stands to reason that the other ports such as the DVI and Display Port will work. Does your monitor or TV have a DP or DVI. If not, you could test it on an old VGA monitor. Most new card come with a DVI to VGA analog converter. If it works on one of the other ports, it is safe to assume that the pins are the cause of the problem and not PCB flex.

When you say the HDMI port's pins, are you referring to the flat piece in the middle with the contact pins on it or the two little silver colored pins on the bottom of the port? I don't think the actual contact pins can be bent as they are all part of the same board.

Are you referring to the pins that come out the bottom and are soldered on to the PCB?

Have you tried a different HDMI cable?

Yes i tested multiple cables, same result. I bought about 660ti and the machine booted up right away. I can definitely say the card went bad. The pins i'm revering to are on the HDMI output on the card.

I have no experience RMA'ing a product, what circumstances need to me met to RMA?
