Need Help Setting Up an NF4 DFI System? Click Here


Recommended Posts

I have made a very long an in-depth thread concerning the NF4 Lanparty offerings. Please take a look at this thread if you have any questions, concerns, or thoughts in putting together an NF4 system. My goal is to better inform those that are in the dark, and offer some advice as people begin to piece their systems together.

Nice thread u got going there deception,I'll bookmark for futur reference. Just a small point however, in your hard drive redommendation u mention Seagate SATA II + NCQ, and also provide a link to newegg.

 

To my knowledge, up to today, Seagate as not announced their SATA II drives and certainly not release any, NCQ yes but SATA II no.

 

Check newegg page again does state SATA II but go down on description and look at transfer rate - neweggg is confused obviously, check segate site for model number and u will see that the drive is a 150mb SATA.

 

Only vendors with SATA II out now is Hitachi (announced this week) and Maxtor as far as I know.

 

Cheers, keep up the good work.

When it was a generic nF4 thread it was very good now I however think U might be out on a limb. Do you have any nF4 SLI to play with yet? If not I'd hesitate to write about what RAMs to choose - there might be some incompatibilities that we dont know of yet.

 

Also on the PSU post I'd be careful to state that the DFI:s want a ATX ver. 2.0 (24-pin) to be sure that noone goes out and buys a ATX 1 now when ATX 2 is out.

 

AMD Rev E? Isn't that the "Venice" if so that isn't out yet that I know of... For futureproofing the post thats ok but right now you are recommending something ppl will spend hours to find and in the end be pissed of when they realize that it's not availeble yet. (And they won't be mad at AMD)..

 

Otherwise as I commented earlier Its a Very Good Writeup.

I think you over-analyzed my thread:

 

1. There might be memory incompatibilities with any motherboard. Nonetheless, I still wanted to provide suggestions as far as what to look at. Besides, if you had looked at some of the results from XS, then you would know that the NF4 boards have pretty much been tuned for Bh-5 and TCCD, which is what I recommended the most.

 

2. I plan to make the 24-pin mention soon.

 

3. I also mentioned that the Rev E cores were not yet available. Some more thorough reading would have made this known.

With the introduction of Nf4 mobos and 24 pin power supplies with 2 separate 12volt rails, I'm a little confused how we calculate the amount power required for the motherboard and how we balance the load on the rails, 3.3v, 5.0v, 12.0v-R1, and 12.0v-R2

 

What motherboard components draw power from the 3.3v and 5.0v rails?

The high-end graphics card is another variable, it draws power from the PCI-e slot and from auxiliary connector via 12.0v-R2 rail, and so how much wattage is delivered through the PCI-e x 16 lane.

 

If I was to build a LanParty NF4 Ultra-D rig how can I add up each rails load?

 

This is where I am so far…. So where am I going wrong?

 

Maximum Peak Wattage No Overclock

 

No1 12.0 volt rail

 

1 CPU = 90w

1 Mother board = 25w

1 dimm = 20w

1 Pci = 5w

1 pci-e x1 =10w

1 pci-e x16 = 105w

Total = 255w @ 12.0v = 21.25w

 

 

No 2 12.0 volt rail

 

2 cdd = 60w

2 hdd = 50w

1 fdd = 5w

2 case fan = 6w

1 hs fan = 3w

Total = 124w @ 12.0v = 10.33w

 

3.30 volt rail =?

 

5.0 volt rail =?

Guest eva2000

bugeyes not sure but i use my APC BackUPS RS 1500VA to measure my NF4/SLI system's power consumption as reported here http://i4memory.com/showthread.php?p=2258#post2258

 

All stock cpu and stock card speeds etc

cpu and cards @ idle = 303W

cpu load and cards idle = 337W

cpu and cards both under load = 424W in 3D tests, and 346-355W in cpu tests

Dimm is either 3.3 volts or +5 volt depending on your jumper setting on the dfi nf4, not the 12 volt rail.

 

To make things easier maybe this will help you.
