i7-4930k on ASUS P9X79 LE LGA 2011 race-horse recommendations please | Stampa

The experimental goal is to have a PC with minimal latency through a combination of higher CPU clock speed, fast memory and higher mobo clock speed.

Just by chance I had a hex core 4930 K and I just ordered last week an ASUS P9X79 LE LGA 2011 for a desktop gaming machine, which is now going to be pressed into service as a HQ Player desktop machine which will be talking to a HQ NAA

OS is going to be WS2012 + AO

The 4930 K has a TDP of 130 watt, and I am think of using a large Noctura cooler, hopefully with no fan in a tower case. If I have to use a fan, not a big deal as there will be fibre optic Ethernet between the HQ Desktop and the NAA.

So I am looking for suggestions / recommendations for 8GB fast memory, how to select a faster mobo speed, and how to overclock the 4930

I am a complete newbie in this field of fast PC's

I'm just a bit puzzled about the goal of your solution, the cure could be worst than disease. A 130 W CPU will generate a large amount of heat and electrical noise, an higher clock more RFI, and last and maybe least mobo get fantastic on board power supply but also a lot of useless copper (it's a full atx form factor) that could act like an antenna for emi and rfi. How do you think to feed this machine? A linear PSU for this type of CPU could be a real challenge to find, so you'll be compelled to use a switching PSU that will generate additional noise.
All that is the theoretical aspect but practice could be different. Personally I disagree with too much power in favor of more balanced solutions, I don't think that the minimal latency way will be so useful on sound quality if achieved with a so expansive price in noise, but I could be wrong, obviously. Try and decide.

I am hoping the TP Links will keep the RF noise out of the NAA. Without the TP links, I would not consider something like this. The TP Link closest to the NAA will be powered by the Uptone JS-2 LPS. I also intend to test out the Corning USB 3 optical to connect the NAA to the DAC, and also trying the Uptone USB Regen which reclocks the USB and feeds clean 5 volt (from JS-2) to the DAC

HD Plex 250 W DC/DC and their LPS should be able to supply with the 130 watt CPU

I am looking at a 4 channel memory setup using 4 x 4GB with 2133 MHz speed to take advantage of the X79 quad channel memory. I want to give Primo Ramdisk fast i/o ;tre

250W is only an approximate figure. You have to see each voltage.
You have to take into account motherboard, ram, hd, I/O for each voltage...not just CPU.
Furthermore, various chips like on board audio and video are still electrically active even though you disable through bios/OS

+1.

The folly continues ;isterico

I have ordered this 4 stick memory to take advantage of the 4 channel memory access which is available with this mobo
Corsair Dominator Platinum 16GB (4x4GB) DDR3 2133 MHz (PC3 17000)

At the end of the day, if there is no SQ improvement, or it actually sounds worse, then it will make a nice game machine ;oookk

I don't think this machine would make sense if one was doing PCM to PCM processing, it's only interesting for PCM to DSD

It's also sold here. Corning USB 3.0 Kabel optisch kaufen bei picturetools

I plugged mine in for the first time last night and it worked no problem with my Exasound

How did it sound ? I don't want to spoil the surprise when you hear it ;oookk

It's a really interesting device. The only really problem that I can see is the terminations A-A, so we'll need a double cable , the optical one and the regular USB A-B, with two other connections on the line. In addiction, but it's only a boring particular, 10 meter of cable are too much for me.
Can you give us some more news about it?

This GE USB cable kit comes with adapters from USB A male to just about every type of USB male connector, so a perfect compliment to the Corning USB with its USB A female socket

Amazon.com: GE USB 2.0 Cable Kit, 6-Ft USB Cable W/6 Assorted A/B USB Adaptors: Electronics

Will be doing further testing, but so far works very nicely between my Surface Pro 3 and Exasound E20 with no handshaking problems. The SP3 is very electrically noisy, so not surprisingly, the SQ improvement was big

I added some ferrites to the Corning USB cable but could not detect any difference in SQ from no ferrites

Sadly my i5 SP3 is not powerful enough to run Polysinc filter so have to use Polysinc - 2s. I found Primo RAM disk made a noticeable improvement when HQ Player directory was copied to RamDisk. Interestingly the SQ was better with the music staying on the SP3 SSD and NOT copied to the RamDisk, so only a small RamDisk is needed.

Unfortunately with my Exasound DAC JPlay is not a very workable option

How was the get together yesterday ? I wanted to come, but I was traveling from USA to Europe yesterday.

I brought back with me the John Swenson designed Uptone JS-2 dual LPS to power my Exasound plus another piece of equipment, may be the NAA side Fibre Media Converter

This week I hope to test Windows 10. I am thinking that recent Win 10 build 10041 has OS supervisor / scheduler modules that have roots in Xbox OS which may explain Win 10 performance improvement over Win 8 & 8.1

Win 10 will be the OS for future Xboxes, as well as for smartphones and tablets

A lot of testing to do this week !

Next week hope to be able to put the Asus P9X79 together. It will have
- 16 Gb 4 stick Corsair 2333 MHz memory
- Samsung Evo 850 SSD
- HD Plex LPS with 250 watt DC converter

Do you think it's worthwhile to put in a better Network Interface Card ? If so any suggestions ?

without examining the substance, this article, gives an explanation, but not on the side of bits ...:
Cables, Bits, and Noise: How Cables Can Make A Sound Difference | AudioStream
finally explains why a cable (USB or other digital) built better is really better in the transmission, not in bits, but in reducing the noise that inevitably degrade the signal and enter in the stadiums of the DAC and preamp. the fiber solution is definitely an excellent (cheap) barrier to noise.
I bet that the sound will be great!
;oookk

The machine is up and running with Win 10

Here were the problems
- it's hard if not impossible to find a CPU cooler for a 2011 socket to handle the 130 watt CPU without a fan running. I actually have a PWM controlled fan running in between the two banks of the cooler

- there is no sonic advantage running a 4 channel memory controller, and may be even a dis-advantage. I have removed 3 sticks of memory

- took me quite a while to figure out which USB port could work with the Corning USB. The useable USB port is marked Flash BIOS !

- so much time fooling around, always listening to test tracks, no time to enjoy the music :mmmm

The CPU load is about 30 pct doing Polysinc and DSD7 converting 16/44 to DSD256
Primo RamDisk makes just as big a sonic difference as it does on my other PC

Next week I should be able to do a comparison with my DH61DL audio LPS machine

I am thinking about a proper HQ Player PC with a CPU TDP of not more than 70 watts. Does anyone have experience with ECC Ram ?
