Hi all,

I just bought a matching pair of 1gb Corsair XMS2 PC2-8500c5 sticks to match the pair I already have (Same part numbers, voltage etc..). The weird thing is, after installing, my machine does not even post. It sits there running but with no BIOS screen showing up or windows even trying to boot. In addition, I'm not getting the usual Mobo beeping (unless I take the RAM out of course). I've tried to boot with JUST the new sticks and the same thing happens. I've even tried to take one stick of my "working" ram and match it with the "non-working stick" and still, nothing. :~

Any suggestions?

have you tried putting the "working" RAM in the slots previously un-occupied slots to check and make sure it isn't the slots?

Core i7 4770K @ 4.4GHz | Corsair H110 | Gigabyte GA-Z87X-UD5H | 32GB 1866MHz Corsair Vengeance
2x EVGA GTX 780 SLI | 256GB OCZ Vector SSD | 4TB Hitachi 7K4000

Asus MBs seem to be finacy about DRAM.
1. Make sure that you completely power down the system, not just the front switch.
2. Replace ONLY the original DRAM in the Original Slots.
3. Repower MB.
4. If system starts, enter BIOS.
5. In DRAM settings force the configuration to 2T and 333Mhz.
6. Save BIOS Configuration.
7. Power down system as in item 1.
8. Insert new DRAM.
9. Power on.

Your new DRAM should be recognized. If not, you may have to reset your BIOS by removing the battery and moving the jumper (with the system powered off as in item 1.). Move the jumper back and replace the battery and power up.
The system should recognize the DRAM, but you will have to reset any BIOS modifications that you had made before, such as RAID support, enable/disable devices (like onboard sound), OC parameters, etc.

If the DRAM still isn't working it looks like a bad set.
