Installed new RAM on my Asus P6t rig, now it wont enter the OS

[omgwtfmoo?]

So I wanted to up my RAM from 6gb to 12gb.

Drove to my "local" Microcenter and picked up the Patriot G-Series DDR3 PC3-10666 1333Mhz Ram kit

Before I tried to install the new RAM, I removed my old RAM which is a Corsair XMS3 DDR3 1600Mhz

As far as I know after looking around there shouldn't be any compatibility issues BUT I guess I was wrong. The corsair RAM was in the orange slots so when I first tried installing the Partriot RAM thats where I put it. PC wouldnt enter the OS so I shut it down, put the sticks in the black slots and tried again, same results.

So I took the new RAM out, put the old RAM back into its original slots and it started up just fine.

So is there anyone out there that has experience with ASUS mobos and RAM or am I going to have to eat the $160 cost of this RAM kit as I cant return it now that it has been in my PC?

Thanks

So you had 3x2GB and you bought 3x4GB?

Are both of these kits rated at the same voltage?

You say "Wouldn't enter the OS." What does that mean? You don't see the BIOS? You hear beeping from the
motherboard? You see the Windows logo and then the computer blue screens?

Can you link these RAM kits and motherboard off of a website?

Have you tried lowering the memory speed on the ram, and/or adjusting the timings to get them to run.
When you move up to 12gb kits, they can sometimes be a challenge to get to run properly

[burningforce]

sounds like you did not reset the bios or change the values in the bios. it might be still using the old config for the memory and not optimized for the new memory you bought.

best thing to do is enter the bios and manually change the memory desired config that the memory is set to run at (speed, timings, voltage, etc) on the package.

or you can just load "optimized defaults" for the bios, this will erase whatever settings it has in there and load the default for the board. then it should detect your hardware and what not. note this will erase whatever settings you set in the bios, so if you overclocked you will have to reenter those settings again.

another thing is to get memtest+ and test the memory one-by-one to see if there are errors, this of coarse is after you set the correct memory info into the bios and save it

OK...By wouldnt enter OS I mean the PC will startup but it wont even go to BIOS (should have been more specific sorry)

Yes i had 3x2gb now I want to install 3x4gb

The original RAM kit was rated at 1.65v and the new ones are 1.5v.

here are the originals: http://www.newegg.com/Product/Produc...82E16820145222

and here are the new ones: http://www.patriotmemory.com/product...&id=975&type=1

As far as resetting the CMOS I have tried both resetting to default values from BIOS and then installing new RAM with no results as well as removing the CMOS battery and installing the new RAM, also yielded no results.

Both of the RAM kits that you've given links to show that they are both 1.65v. I would try this next:

Put in 1 stick of memory and see if the system will boot. If it does, see what the BIOS is reporting for timings and voltage
and make the necessary adjustments if needed. After that put in another module and see if you still get a successful boot
until you can install all 3 modules.

If it doesn't boot, keep trying each individual module, one at a time, in each of the banks. You don't have to try every single
bank but I would test at least one bank of each color from the first channel. If none of the modules will boot with just a single
stick in multiple slots then...

I don't know.

DDR3 is DDR3 and triple channel is no more special than dual channel. If you have access to another system that uses
DDR3 I would suggest trying the sticks in there as well. If they won't boot then I would guess they're bad. Even if you
can't get your money back through Micro Center the RAM is still under warranty through Patriot.

Also quoted directly from Patriot's site:

How come my brand name computer will not boot with the Patriot Low Latency Memory kit that I just purchased?

Most brand name computer such Dell, HP, and Compaq has limitations in their BIOS not allowing low latency memory
modules to function properly. Most of the time, they also disable memory settings in BIOS so users are not able to
manipulate them. Since these computers has BIOS limitations, our Patriots Low Latency Kits are not recommended for
these brand name computers. We certainly can recommend any of our compatible Signature Line memory.

Thanks Fenril, I've now had some improvement. I got my PC to boot with 2 sticks of the new RAM in it, BUT it will only recognize one of them. I tried putting all three in, switching which port i put each stick in but it will only boot with 2 or less.

Also in regards to the quote from Patriot, I built my PC from the ground up so I dont have to worry about limitations

thanks for the help so far, hopefully I/We can figure this thing out. I got 4 level 80 shammies to level

OK, now my PC will recognize all 3 of the sticks but only in the first two orange slots, the third one hasn't been responding.

As far as the black slots go, i tested just the first one and got nothing so i stopped there since I saw some improvement with the orange slots.

guess i'll have to keep trying

While this can be the nature of the troubleshooting beast, sometimes hardware can just be broken. Perhaps there is a BIOS
upgrade (or downgrade) for your motherboard which might help.

If all else fails, read the manual. I mean which slots are set up for which sticks? I always have to check which is A1 or B1
