HD5570 and M2N68 AM+ mobo

You wont face any problems. All PCIe devices are backwards compatible with old versions.
HD 5570 will downgrade and run at X16 1.0 speed.

some one advice me that "PCIE 2.1 will not work with PCIE 1.0 boards, but 1.0 cards will work on 2.1 boards"

Its the other way round too.
Just google a bit, you will know.

some older nforce chips have issue with pci-e 2.1 gfx cards but a bios update should fix this though.

Last bios update for said Motherboard is at 20-11-2010.....

yup should work fine
just make sure you have a psu to power it all

If not supported due to said issue.. what can i do?
Recommend good AM3 mobo to support HD5570......

i have latest bios............
Can i try a modded bios available in *forums.mydigitallife.info/threads/16186-Asus-m2n68-am-plus-modded-bios-with-asus-slic-2-1?

^^ no need to try any moded bios - the last version of the official bios should work fine but if not we can think about any other alternative solution.

I second this.

Yup, first try updating BIOS. If it doesn't help only then go for a new mobo. Else no need to spend for a new one.

HD5570 is not working with my mobo ASUS M2N68AM+.....no display.......
tired after several attempts....
Today i got for Asus M5A78L-M-LX for 2.9k with VAT...
I have no expereince on replacing motherboard..However i did cabinet change last week without adding anything new...
Is there anything need to be followed during mobo change?
i am scared of jumper settings...
please advice....

First of all you have to get new DDR3 RAM as its an DDR3 mobo. Get corsair 4GB DDR3 stick for 1.3k.
Well just take out your old mobo, asus provides a Q-Connector, so connect all system power, HDD and reset cables to it and connect it to mobo.
Also take out your HSF, clean the TIM applied. Get a new TIM like CM Thermal Fusion-400 for 500bucks and apply while placing the HSF on the processor.
If you have any doubts, watch some youtube videos on assembling a PC. Also there is an incomplete assembling thread in 'Draft' section, it has link to a good assembling video. Watch it.

You can sell your 3GB DDR2 RAM+Mobo+8400GS for around 3.5k easily too.

already i have 4gb ddr3 ram(dynet) from my friend....
what abt jumper settings..?

No need of any jumper settings.
Just mount the processor, RAM and graphics card in their repective slot/ports. Connect PSU cables properly, that's it.

I think the Motherboard manual which came with the motherboard will help you a lot. Almost all the cables are coded, and can be attached to the mobo in only one way. The manual has a layout diagram of the motherboard.
