More Nehalem Info - Memory, Overclocking & Voltages

I hope so! I thought Intel were going to encourage overclocking with the Nehalems?

Intel's idea of overclocking and ours are two different things.

TBF I can't see the voltage problem been too much of an issue for most people. The chips overclock well at low voltage. I can see them running at 4-4.5Ghz not been a problem even with the memory issue.

Extreme overclocking (4.5Ghz - 5Ghz) is going to be very difficult and will depend a lot on your choice of ddr3 memory I would guess as that is going to be your limit of your overclock (good mobo required as well of course)

Sorta feel sorry for people who paid a premium for ddr3 memory with a current setup in the hope of transferring it over to Nehalem when the chances are they will end up buying new and better memory again.

To me, it is just not looking appealing. The heavy cost burden of new cpu, mobo and quality memory just maybe get if you are lucky a 10% better overclock over current cpus for maybe two to three times the cost just doesn't seem worth it.

Lots of the new stepping cpus are doing 4Ghz without any effort and 4.5Ghz.

With the new cpu not been any faster clock per clock, for me I will be sticking with the cheap current offerings.
 
I'm sure I read somewhere that mobo's are coming out on which you can set different voltages for the cpu and ram. Only recently too.

I'll see if I can find it.


Well, here is one.
 
The main subject that needs adressing for those of us with DDR3 already is if we can buy just another 2GB ram stick to add to our current 2 x 2GB sticks for Tri-Channel memory. I don't really want to buy 2 more 2 x 2GB ram packs which may or may not allow for 12GB Tri-Channel.

Though TBH by the time i can be bothered to switch, my ram will probabaly be worthless anyway!
 
Looking on OcUK at the stock voltages on DDR3, the only stuff less than 1.7V is only 1333MHz. Slooowww.

Edit: Though this may hint at an acceptable max voltage for their 45nm chips - 1.65 V :p
 
But would it be safe running the cpu at this high voltage throughout it's life? I would have thought that it would severely reduce its lifespan or give high temps.
 
Are you sure this is going to be an issue as amd have had memory controlers on chip for a while now and you can run high volted mem. with them:)
 
Hard to tell.

But it's serious enough for Intel to tell the motherboard manufacturers to place warning stickers on their boards.
 
Gibbo says that it isn't in effect on his board though - and most memory manufacturers are going for a very radical change to better processes currently, there should be much lower voltage kits soon - anything over 1.3v will still be completely unacceptable with a stock CPU cooler, i don't know what they're thinking.
