Hello,so my brother recently bought new computer peices and when all put together the dram_led came on red. we later found out that the motherboard supports up to 1333 Mhz ram but the ram we have in there is 1600 Mhz can this be causing the issue? also the screen doesnt boot it stays black.

1600MHz RAM will work fine at 1333MHz and the BIOS should automatically select the lowest common denominator if RAM settings are on AUTO. If you overrode any RAM settings, you may need to reset the CMOS to make the BIOS reload safe default values from the SPD EEPROM.

If it still does not work after this, try a single DIMM at a time in different slots just in case either of them might be bad and preventing boot. If you still cannot get through POST with either DIMM in any slot, there either is an incompatibility between the DIMM and board layout or between the SPD parameters and BIOS.

If you had known-good RAM for this system, you might want to boot using the previous RAM, update the BIOS, reset memory settings to default and then try upgrading the RAM again.

all peices were bought brand new and were never used. also the computer has yet to boot properly so my brother hasn't touched any bios settings we have tried benching it we have tried to use just one ram in every slot, we double checked the wires and everything. its very fustrating

The I5-3570K Is DDR3 1600 By Default but will run slower,So no problem there and the board should support the faster RAM also.I believe your problem is for that board to accept an Ivey Bridge processor Your gonna have to have the latest Bios setting for it,So if you have not already, Update the bios.

You should be using a series *7x chipset (z77/z75 if you want to be able to overclockm h77 or b77 otherwise) motherboard with Ivy Bridge CPUs, this guarantees that the stock BIOS supports IB CPUs.

Some older boards may support IB out-of-the-box but many will require BIOS update first, which is problematic if you do not have a spare Sandy Bridge CPU to do the upgrade beforehand.

If your motherboard's BIOS does not support IB out-of-the-box, pretty much unless you can borrow a SB CPU just long enough to update the BIOS.

Might want to inquire with the vendor for a trade-up.

Some boards will let you flash the bios with a usb flash drive,You would have to go to the Motherboard support site on another computer and follow the directions.I'm not sure if your board supports that or not.You would have a button to press on the IO or the board after USB flash drive is inserted into the usb port and you could do that with your Ivy Bridge still installed.

Then it must be the bios,You'll have to get a Sandy Bridge from somewhere long enough to flash the bios.That board does not have the bios flash function that I mentioned earlier.Sorry guys I couldn't be more help.You can contact ASUS I have a Z77 board in my wife's computer that we just built with the same core I5 you have and we had a problem.They have great customer support.

I'm not sure on that I always do my own work.One other thing though If the Computers shows its still powered on after restart try connecting monitor with a VGA cable,Sometime HDMI and DVI will not work until driver disk is installed.

the issue with that is that the motherboard only has a built in DVI And hdmi port and the only video card my brother has has only i think a DVI plugin. at the moment he plans on using the built in graphics.
