Hi everybody!
need some help in getting my memory settings working better on my new pc with 8 GB RAM.
I started with 2x2 GB of CMG4GX3M2A1600C7 Corsair dominator GT that I succeed to run at a nicely 2200 FSB with a Gigabyte UD6 Mobo and a i5 750 CPU.
Recently I bought additional 2x2 GB of the very same RAM modules and with the same settings I had in the BIOS the system wouldn't boot.
Loosening timings (setting them to auto) made the system starting correctly. Now I have my system running at 1760 FBS, but would like to hit the 2200 I had earlier.
Is that possible? In that case, what settings of the BIOS I have to work with?
Appreciate any kind of suggestion
 
I don't think you will be able to hit the same speeds with 4 modules as you had with 2. The extra sticks put more stress on the memory controller - so backing off on the RAM speed is needed to get it stable.

However, I bet you aren't losing much actual performance when running at 1760MHz compared to 2200MHz.

I dont remember exactly, but I suppose that in 3D mark 06 I get the same figure (around 24K), but in Sisoft Sandra memory bandwidth benchmark I went down from 24 GB/s to the actual 22 GB/s..... My intention is only to know what is doing my system more sensible to frequency settings and if there are some BIOS settings to analyze particularly when handling with 4x2 GB RAM modules
 
You are using your computer or just watching memory benchmarks ? I ask because there is zero point in high speed RAM, as the gains are neglible. (As links will get ****-ed, google for "Corsair vs. Kingston Intel Core i7 LGA1156 memory round-up" and look at the results).
 
My interest was principally in understanding the reason why I was getting a worse result in having 4 modules instead of 2. Is there a synchronization issue, timing problem...... also because my motherboard Gigabyte UD6 had 6 memory slots and was wondering if their using is independent from the number of modules present (despite of the white ones)

This is a physical limitation of the memory controller. It simply cannot run 4 modules as fast as it can 2 modules due to the increased electrical load.
 
Mmmmm! I'm curious here...Are you saying it is a Waste of time & Cash haveing 6GB Ram or more. ?
If we do not overclock, which is better, 4GB or 6GB. Use for Video/Photoshop/Burning/Music/Bryce etc.,
I always thought that the more Ram you have the Better n faster it is.

It's not a waste if you are going to actually use it. If you never approach using 4GB, then 6GB is a waste and increases heat, wear on the memory controller, costs more, etc.
