Just to clear up a myth that seems to go around as well. Running ram at 2000mhz is very easy with a 975, for the simple reason that you can set the ram divider to 2000mhz and just use the multi's to get your desired clock. The reason that it's hit and miss with a 920 is because to get to 2000mhz you have to be running a BCLK very near to the limit of the QPI link (4000mhz). With the 975, you only need to be running a BCLK of 133 to run the ram at 2000mhz.

You still need a chip capable of 4000Mhz Uncore which I would've thought is by no means a guarantee even with a 975.

Another myth, i'm afraid. All you have to do is select a lower GT/s and Uncore will then drop. As it happens, i've yet to come across any 975 that wouldn't do well above 4000mhz.

The only time you would even want to consider the 975 extreme is when using extreme cooling (ln2,dice,phase change and the like) for 5-6ghzghz speeds.

Personally id go for the 920 and using the saving to get a proper decent water setup, and then overclock the 920 to mid 4ghz region.

Although it isn't a breeze getting RAM to run at 2000MHz it is quite straightforward - I have the Gigabyte UD5 and on this board it's simply a case of playing with some voltages and getting it to run stable at BCLK 200 with a 10x RAM Multi, and all other settings required for my 4.2GHz OC. Not easy but it didn't take days of testing either!

As for the OP... Get a 920 D0 chip and then spend what you've saved on some SSD's! (or at least that saving will help on your way to your dream rig).

Isn't 1600MHz RAM slightly overclocked amazing anyway? What do you plan on using 12GB of 2000MHz RAM for?

buy the 975 - send it to me and i wil send you my 920 that does 4.4ghz 24/7

deal?

Well tomkat2009 the guys here have pretty much told you the same as we told you in the posts you made at our forum

and as i stated in that thread if you don't fancy oc yourself buy one of the excellent bundles from here

thanks guys, a resounding 920

What about a skulltrail qx9750 (x2) vs i7?

JonJ678 · 1 Oct 2009 at 12:00

Silly question. Don't buy the skulltrail.

wait for the 6 core 12 threaded monstor to come out if you want 'the best' as that will be EE only if i belive right and get a 920 in the mean time

ralv585 · 1 Oct 2009 at 12:23

920, all the way

tomkat2009 · 1 Oct 2009 at 12:24

why not?
