installing new ram on my alienware problem

Try this.

Turn on XMP. Go into the Overvoltage Config and set QPI and Uncore voltage to +200mv. Leave everything else on Auto. Don't change anything that the OC1 or XMP setting didn't change other then the QPI volts.

My last post is gone? anyway mate that didnt work but thanks anyway for the help

You can't say those words or the Moderator will just delete your post again (or possibly the whole post thread).

You have to keep it clean (their rules).

BTW you also cant start a sentence with what you did here. I can't even type it because it will be removed.

Intel made XMP so noobs could OC. The problem is if the XMP fails then you need to understand why. You need to learn how to OC memory.

You may not know this but you are close to getting it to run. You didnt get the OC fail message so you just gotta play with it some. You may even get it to where it says Starting Windows and then crash right at the desktop. All of this means you are really close but not quite there.

Whats going on is your XMP profile is having trouble setting the correct settings on the board. This can be due to many things. It happens from time to time. You may have older XMP memory that doesn't have the updated XMP profile on it or maybe the motherboard is having issues with the XMP settings. Again this does happen from time to time and when it does you need to find out which setting is off and then change it yourself.

The memory speed is based off the CPU multiplier. The stock memory multiplier is 8x. So lets say you have a 4g OC on the CPU and you got there by using a 200 BCLK. The memory will take that 200 and multiply it by 8x for a 1600 mhz memory speed. Stock CPU speed is 133 x 20. So your memory will take the 133 x 8 for a 1066 memory speed. The board will let you set memory multipliers yourself. It will let you use 6x,8x,12x for sure. I do not know if your board has other multipliers but it may. Lets say it also has a 4x or a 10x but you need to look in the bios to know for sure.

The best way to go about your OC is to turn on the XMP profile and then change all the other settings. This way the memory will run at its rated 1600mhz no matter what the BCLK is set to. Just leave the memory multiplier on Auto.

Next you need to set the memory volts to 1.65v. DO NOT go over 1.65 or the word FRIED will enter your life.

The next setting to check is the timmings. I am going to guess you have ether 8-8-8-24 or 7-7-7-20 stock timmings on your RAM. If it is 7-7-7-20 RAM try to run them a little loose at 8-8-8-24 untill you get it to boot and run. Then you can play with making them tighter.

I had the 1600 and the XMP profile worked like a champ but my 1866 XMP profile was setting the wrong QPI volts. For me I needed +200mv for the QPI. My stock QPI volts is 1.140. Adding +200 gives me 1.340 QPI. DO NOT go over 1.36 QPI or AGAIN the word FRIED will enter your life. You need to find out what your memory QPI volts need to be and what your board stock QPI volts are. Call Corsair to get the memory QPI volts.

You should go download Everest. This will tell you what the board and memory volts are along with other useful information.. When Foxconn makes the board they may try to make all the QPI volts 1.140 but it doesn't mean all of them are. Yours may be 1.150 for all we know.

If you do get it to boot to your desktop you will want to see if its stable. You will need to download Memtest and Prime95. Run Prime95 for about 10min each time you change something and make it to your desktop. This is a quick way to check if its stable. Then when you think you have it where you like it run Memtest overnight. You want to run no less then 5 passes of memtest. If you get errors it will mean ether a timming or volt is wrong or you have a bad stick of memory. If it truly is a bad stick don't worry Corsair will replace it for free.

 This is the short list for you. There is more but this is the basic and should get you running. If all of this is to much for you then call Corsair. They will be more then happy to help you get it working. Corsair has the best support I have ever come across.

@ Morblore - Excellent post on getting XMP memory to work.

Thank you so much for this info mate.. im really sorry for saying what i said but this problem it just getting me down big time.. i will do as you say with this an hope i can get it to work..

thanks again for this super reply.

Thank you so much for this info mate.. im really sorry for saying what i said but this problem it just getting me down big time.. i will do as you say with this an hope i can get it to work..       thanks again for this super reply.

And like I said if you have any trouble at all just call Corsair. They will be more then happy to help you get it working.

hi morblore. i done what you said and i got the XMP to work, but still have problems,

these are the changes i made for XMP to work.

1.  OPI freq on auto

2..... enabled xmp 

3.... memory ratio on auto............................... as you said above my goes from 6 8 10 12 14

4.... memory volts to 1,65

5.... i couldn't get my pc  to start at  +200mv but works on 120mv 160mv my QPI DEFAULT is 1.2v

6... i didnt change my memory timmings they are 9 9 9 24.      73/ 10/ 5/ 5 /5 /2t

7... left dynamic opi vcore offset as default (by cpu vid)

8... i never done any OC on the CPU so it was at 2,67GHz

but i had to change one thing because when it booted up i went inot the bois but the memory speed was 1838mhz  at 133x14.

but the memory was still on auto...  so i change the memory ratio to 12 instead and i got 133.12 1600mhz.

morblore i thought when i got the XMP on it could set the memory speed to 1600. no matter what BCLK i set. what am i doing wrong on that?

so once i had it on 2.67GHz 1600MHz i done a prime text with no problems,, i was so happy until i tryed to set the BCLK up abit from 133 to 150. when booted up i went into the bois again and see the the memory was 1800MHz instead of 1600.. with the pc crashing again :(

so the problem now i have is when in increse the BLCK the memory speed goes up again even with XMP ON.

i suppose something is all wrong but i dont know what. :(

That means,as we already know, that the motherboard is having issues reading the XMP profile. So you gotta set the memory multiplier by hand. Not a big deal. It is time to treat your memory as if it does not have a XMP profile. Plus I forgot I have a EE CPU so I dont need to up my BCLK to up my memory.

Keep in mind that for memory there are two ways to judge its speed. One is timing and other is the speed of the memory. You can have 1600mhz memory with very tight timings that will make it as fast as say 1700 mhz memory with loose timings. When I say fast I mean in benching them. The key to OC'n them is to get a high speed with tight timings. You want to find the middle ground.

 So now that you know how then do the 150 x 12 for a 1800 mhz and play with volts and timing to see if that is stable.It also my not ever run at 1800 mhz. It may need more volts to run at that speed or loose timings. Maybe both. Nothing wrong with going higher and since you have memory made for OC'n i'd try that first. if nothing else you will find what the top speed of your set is.

 If it is not stable then drop it to 150 x 10 for a 1500 mhz clock and then drop the timings too. Maybe try 7-7-7-20 first and if its a no go try 7-7-7-24 and then 8-8-8-20 and so on.  You can also change the command rate from a T1 to a T2. T1 is faster but for a higher speed you may need a T2. Changing your QPI Link from auto to a manual setting can also help, or so I hear. I have also heard to turn off other things like Cstat,spread spectrum and Turbo. /shrug

At 1500 mhz you should have no trouble running tighter timings then the stock.

Don't forget you can raise the BCLK and drop the CPU multiplier to reach the same CPU clock while giving you a number you can use to reach 1600mhz on the memory.

You could put the CPU at 160 x 18 for a 2.8 ghz CPU clock. Then set the memory multiplier to x10. That would give you 1600mhz memory with a 2.8ghz cpu clock. See what I did there? Just play with it till you get it to where you want it.

And REMEMBER the only two volts you ever want to touch are the memory and QPI. Set the memory to 1.65 and leave it. Never touch it again. The QPI is what you need to play with but it sounds like you may have found your QPI volts. Keep in mind that even at the QPI volt setting you have it may boot and run for an hour but crash. It may be close but not right on the money. On my system I have 3 QPI volt settings I can boot with but only one is 24/7 stable. No way to find that volt other then memtest or playing a game till it crashes.

Check out overclockers.com. You should find a lot of info to help you.

I am 100% sure you will get it. It sounds like you are doing a great job. Don't give up:) GO read this. Don't skip any pages. http://www.maximumpc.com/article/features/ultimate_core_i7_overclocking_guide_we_push_nehalem_its_limits

@Morblore

hi mate can i put my QPI over 240mv+?

ive done everything to get it stable but i just cant get it stable im doing it manual not using XMP. the pc is stable for the day but the next morning when i boot up the pc i get the blue screen so boots up and everything is good no memory probs at all. until the next morning boot up same thing happens again. drive n me nuts LOL
