Thanks Scott.

Whats the issues with the Ram on the X79 mobos? Is that the Samsung green stuff ? I can only seem to find it in 4 gig modules

So would this combo be better ....

i7-3820 3.60GHz (Sandybridge-E)
Gigabyte X79-UD5 Intel X79

lots of ram incompatibility on X79 vs Z77
especially when fully populated (8 sticks)
or using 8 gig sticks.

you can get past it sometimes by downclocking the 1600 to 1333 (sometimes forced to do 1066 even)
samsung LV ram in 4gig sticks is all you will find the 8 gig samsung is hard to source and goes mostly to OEMs..
often the Eeproms arent programmed right with other ram as well so XMP etc will not auto work always
most likely will require manual setting of the ram.

if you can get the samsung you should be ok.
done know about the "green" aspect ..

You want to make sure the motherboard has an Intel chipset.
Also a good idea to know the maximum RAM the motherboard will handle.

all intel processor boards have intel chipsets anymore. no more 3rd party..
 
and actually fully populating the board can cause issues

Hi Scott this is the Green stuff I was referring to its the only Samsung Ram I have seen in the UK. http://www.overclockers.c...id=701&catid=8&subcat=

yes that would be ideal

so why not get the newest.

So it looks like the pros are not finding the overheat/throttle problems when overclocking Ivy Bridge, that have been reported elsewhere? Is that not an issue, or just not an issue at the level of OC you do?

@ Scott Had a look at the graph there sorry I overlooked it before. Looks like the 3820 kicks the ass off the 3770K ?

Not when you overclock it to 4.5ghz, the 3770K is a nose in front.

yeah but then you can OC the 3820 as well and have far better memeory bandwidth. while the average OC for the 3820 is only 4.2GHz is still kills the 3770 @ 4.5GHz

at first yes very much... in fact we were like "so much for die shrink and thermals being better"
it took a decent amount of tweaking in the bios to get them to behave as they should.
when done right they actually run a tad cooler than Sandy. (a small tad)
