So: an i7-3770K system draws about 100W when running flat-out, meaning that, if I don't want a GPU or hard disc drives, I ought to be able to fit it in really quite a small case.

Do there exist budget mini-ITX boards with Z77? The ones I see seem to have fancy integrated wifi and cost $200, which isn't what I want.

Our i7-3770K system draws a max of 160W. (See post number 76.) Right now it is using ~138W, not counting the LCD.

Thanks for the replies, everyone.

I've settled on an Alienware X51 (with a GTX 555) from Costco, which comes out to be slightly cheaper than from the Alienware website. The GTX 480 would have been my ideal choice, but it doesn't seem to come with new systems anymore, and I don't really have the time or expertise to build my own computer. Nevertheless, I hope my new rig will serve me well.

Too bad you can't substitute a GTX 570 or 580.

Just curious, sorry if answer is above, how much did you pay total?

1. Should I get the fastest RAM I can afford or is anything over 1600(?) of limited benefit to GIMPS?

2. Some Motherboards say: "Onboard Video Chipset Supported only by CPU with integrated graphic". i5-3570K says it has such. Does this mean it has a video card capable of standard video requirements. I'm not a gamer ... and the grandchildren are under 6. i.e. Gigabyte GA-Z77X

3. Or do I really need a video card? I don't think I want to enter the GPU arena yet.

1600 MHz should be sufficient for that chip.

The integrated graphics will be sufficient for anything but games (and other rendering, heavy Photoshop use perhaps, etc.). Video will be fine.

Not unless you want all the credit that comes with it.

I have found in my limited testing that using 2133 MHz dual channel setup removes my memory bandwidth bottleneck when running 4 workers of Prime95 LL on my i5-3570k CPU's.

It seems to get me over the bottleneck that can be created by having only a dual channel memory controller and too many cores running all out.

With a Quad channel memory controller 1600 MHz memory seems fine. I even think slower 1333 MHz memory seems to run fast enough to keep 4 cores of workers of LL running efficiently.

RECAP: with dual channel memory controllers and 4+ cores maxed out

2133MHz memory > 1600 MHz memory > 1333 MHz memory

and there is a noticeable diffence in iteration times between the various speed memories running 4 cores of LL.

in a quad channel memory config like you find on X79 motherboards boards while the same statement above is true my measured differences in LL iteration speed is very tiny and near insignificant when running 4 cores. If you have a hex core Sandy Bridge Extreme the extra speed in the memory may be more noticable. Since I have been unwilling to spend the extra $300 or $800 for the hex core I have not been able to test this. (The bench marks I have run have shown the faster memory to have more bandwidth it just has not lowered my Prime 95 LL iteration times)

henryzz · 2012-11-13, 22:05

At the place I use 2x4Gb is £34 for 1600, £40 for 1866 and £54 for 2133. Personally I would go for the 1866 as there isn't much price difference.

So I can get 2X4Gb 1600 for $39; 1866 for $46; 2133 for $49.50
but the latency goes from 9-9-9-24-2N to 9-10-9-28 to 11-11-11-30.

Code:

G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-8GBRL  $38.99
     

G.SKILL Sniper Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-14900CL9D-8GBSR  $45.99
     

G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 2133 (PC3 17000) Desktop Memory Model F3-17000CL11D-8GBXL  $49.49

I don't know a lot about these numbers but I know bigger means slower so I assume this negates SOME of the higher speeds? But each is still overall progressively faster?
Thanks

OK...maybe a little GPU (I mean video card

)
6 years olds get older fast and want to play 'real' games; and photo shop is not out of the question.

I can get what seems to be decent in this forum for under $150. (GTX 550/560).
I really don't want to spend more on my GPU than the CPU.

What matters more if I ever get to CUDA-Lucas OR mkfaktc?
Core Clock Speed?
Shader Clock Speed?
CUDA Cores?
