Memory change problems

Great site guys, I'm so glad my friend sent me this link.
Anyway, I recently bought a pre-built computer from Cyberpower and have had no problems except when I changed the memory.
My motherboard is an MSI X48 Platinum Intel X48 Chipset (QX9650/9770 support) and I am running Windows Vista 64.
The memory that came with the system was 2G (2x1G) PC1333 DDR3 PC3 1066 generic corsair memory.
I uninstalled that with the system turned off and installed 2 2G sticks of Corsair XMS3-1600 Memory (CM3X2G1600C9DHX). I had some problems with the system freezing at random times. I then found a good deal and purchased 2 more sticks of the exact same memory for a total of 4 2G sticks. Afterwards, my computer seemed like it got worse, freezing on startup at least once every time and then randomly during gaming, web surfing, word processing, etc... I checked the bios and saw that the memory was set to 'auto,' but it didn't seem to be working properly (I'm guessing).
I reinstalled the original memory and have had no problems since, but of course, the performance would be improved with the new memory.
If you could provide me with a detailed guide as to what settings to change in bios so my new memory would work, I would be very grateful.
Thank you for your time.

 

Just a bump to see if anyone can help.

 

My bad, I thought this website actually offered help.

 

We're volunteers here. Give us 48 hours or so, or go pay someone to put up with your bad manners and attitude. I don't have to help you at all, and if you keep this up I'm going to move on to someone who is less of a jerk about it.

That said, from where I stand, you've had three sets of memory malfunction in your motherboard. That means it's not the memory, it's the motherboard that is causing problems, and you're probably right that if you were to set your voltages and timings right you'd have less problems.

I've owned a lot of Corsair memory, and they all had the timings and voltage printed on them. I'm not going to give you detailed instructions, partly because if I write them here and you follow them and they are wrong I'd be liable, and partly because your motherboard manual already has it all spelled out for you. Read it, and then set the values printed on the memory. Problem solved.

 

Sorry if you are offended. I waited for a week with no answer so I thought I was written off.
Actually, I never wrote that the first set malfunctioned or that three different sets of memory failed. I simply wanted faster memory in larger sticks so I replaced the original memory.
The set I used to replace it was 2 sticks of 2GB Corsair Dominator. That's when the problems started. I then added 2 more sticks of 2GB, which filled up all four slots. That's when the system started freezing much more frequently and every time I started up for the first time of the day.
Ever since I replaced all the Corsair memory with the memory the system came with, there have been no problems whatsoever. The problems started when I installed different memory and then maxed out the memory slots. This tells me that the problem is most likely the memory itself or the way the timings are set in bios, not the motherboard.
All of this is plainly written in my first post.

 

Just click on this link http://www.crucial.com/# to do a Scan My System and also the Crucial Memory Advisor Tool. It will tell you exactly what your computer needs/wants. Of course you don't need to buy from them.

 

Thanks for the advertisement, Oma, but no thanks
My post clearly states that I don't need to buy memory, I need to get what I already have set up properly.

 

Yep. Check what the voltage and timings are set to in your BIOS. Then check what voltages and timings the modules are rated at... if you have two sticks of 1.8V memory and two sticks of 2.0V memory, you'll end up with weird problems, so make sure that all installed modules are rated at the same voltage. Then set the timings manually.

And that is plainly written in my first post

 

Changing the timings fixed the problem so I'm now running with full 8G memory.
Thanks much!
