MSI GT680R 16F2 CPU Upgrade i72630QM 2nd Gen to i73920XM 3rd Gen

[moral hazard]

The 2630qm should support 1600mhz ram.
At least that is what I had when my 2630qm was in my P750.
Now that I took it out and replaced it with the b960 my ram went down to 1333mhz.


All you will need is to flash an unlocked bios and change the ram setting to 1600.

I don't think so?

Intel's spec's are 1333 max.

See:
Intel® Core

Search the forum and see for yourself

The default is 1333. But with a modded bios you can change that to 1600 and it will work 100%.

Intel probably writes 1333 because most notebooks don't have that option in the bios to change ram the frequency.

I had to hardcode that value into my bios.
But with the Gt680 you can flash the unlocked bios and easily switch between speeds.

Thanks, hmmm....

I thought the cpu determined the RAM speeds? Not the MB BIOS.

Live and learn, I guess.

Oh, when set to 1600 - does it really change the performance (even in benchmarks) or is it simply ignored by the cpu?

[moral hazard]

I didn't do any benchmarks, I just flashed the bios and checked the speed with cpuz.

And I do believe the CPU can determine the ram speed. But in this case the CPU supports 1600.
I don't have a clue why it defaults to 1333.

Pretty sure if I flashed my modded bios now with my pentium b960, it will probably not work at 1600.
But I don't want to try it because then I would have to put the 2630qm back inside just to flash back to stock.

the cpu is the one that determines the speed. Since the memory controller is in there. But the deal here is that all quads do support 1600mhz, since the chips are essentially the same, just the binning that makes them different.
