Intel DX58SO & Thermalright HR-02 boot problems

[Xigga]

I'm having a problem where the system will not POST or display video if there are sticks of RAM in slot B and/or C of the motherboard when using the Thermalright HR-02 heatsink. I've tried many scenarios and have found that the system will boot if:

• The heatsink is held in place without the tension bracket, no pressure applied
• The tension bracket is barely on, almost like it's just making contact with the screws

The heatsink's mounting hardware doesn't seem to be touching anything except the metal plate behind the motherboard. The system does not seem to boot if enough pressure is applied, no tension bracket in. I really can't make sense of this because it boots up just fine with one or two sticks of RAM in the first two slots. Note that the system boots up fine with the stock cooler. I've tried booting with all the auxiliary power connectors in and none, but no results.

Here are my system's specs:

Motherboard: DX58SO with 5456 BIOS
Processor: i7 920 c0
RAM: 4x OCZ3G1333LV4GK
Power supply: Corsair 520HX
Video card: nVidia GeForce 460GTX

Had the same issue. Had to remove battery to clear bios, which got it to post once. Locked up again. Had to RMA

Sounds like it's bending the board and causing an open circuit somewhere

Warranty?

I'll have to check on the warranty with Intel but if the bending is causing this, then there might not be hope with a new motherboard

I wish I could sell it off and get a less fickle motherboard, but it seems to be worth dirt on eBay.
