I'm little bit confused about the ASUS Z9PE-D8 WS board.

I understood it like this that PCIe slot #1 to #4 are connected to CPU#1 and PCIe slot #5 to #7 are connected to CPU#2.

hardwareluxx.de - they write:
»Insgesamt hat man somit 72 PCIe-Lanes in der neuen PCIe-3.0-Spezifikation zur Verfügung - das ist eine gehörige Bandbreite, die hier zustande kommt. Zusatzchips als Bridges oder ähnliches müssen allerdings nicht verwendet werden, da zwei CPUs zum Einsatz kommen: Die Slots 1-4 gehören zur CPU 1, die Slots 5-7 zur CPU 2. Entsprechend läuft die Kommunikation im Quad-SLI über den QPI-Bus und nicht direkt. Da im Dual-CPU-Betrieb zwei QPI-Links zur Verfügung stehen, sollte die Bandbreite aber vollkommen ausreichen. Sämtliche Onboard-Komponenten werden hingegen über den C602-Chipsatz angebunden.«

Google translator said:
»Overall, it has thus 72 PCIe lanes in the new PCIe 3.0 specification is available - this is a proper bandwidth that comes here. Additional chips as Bridges or similar but must not be used as two CPUs are used: The slots 1-4 are CPU 1, the slots 5-7 to the CPU 2. In accordance with the communication in Quad SLI runs over the QPI bus and not directly. Since two QPI links available in dual CPU operation available, the bandwidth should but perfectly sufficient. All onboard components are, however, connected via the C602 chipset.«

The board have two QPI, one each for one CPU.
I don't use SLI or CrossFireX cables.

So does this mean, that VGA card #1 (in PCIe slot #1) and VGA card #2 (in PCIe slot #3) communicate with CPU#1 and
VGA card #3 (in PCIe slot #5) and VGA card #4 (in PCIe slot #7) communicate with CPU#2 ... (I understood it like this) ...?

OK, what happens if I use -cpu_lock in cmdline...
What happens if the project app on VGA card #4 will be fixed on a CPU-thread of CPU#1 (they are not connected)?

Or the two QPI are connected in the northbridge and it could go the above mentioned?
Or the app don't get CPU support and go in a never ending waiting loop?

Thanks.

I sent E-Mail to the admins.
Because 'not in DB' and '.vlar's to NV GPUs'.

I got E-Mail from Eric, he's looking to it.

Thanks to you, and also to someone other for PM. :-)

Until now I wouldn't like to download and burn a DVD. I never did this.

I sent an E-Mail again to the Online-Shop.
I want a new/other DVD.

I sent also an E-Mail to Microsoft, if they could help me to get a new/other DVD (the Online-Shop must send a new/other, or maybe they can do this).

If there is really no way that I can get a new/other DVD, I must burn a DVD.

If then, if I would take the Windows 8.1 x64 DVD, IIRC, during installation, very early I must enter the Product-Key, if I use then the Product-Key of the Windows 8.1 Pro x64 OS, the installation of the Windows 8.1 x64 will continue?
(Just the Pro have dual CPU support. Maybe the installation of 'non Pro' don't work because of this?)

Thanks.

I asked at the manfacturer (for some weeks, because I had the same idea ;-) , if I could remove the backplate of the HD7990, the support said it's urgently recommended to let installed the backplate.
It cool the PCB and the VRAM.
The 1st VGA card, 1st GPU, just in BIOS, the backplate was so hot that I couldn't touch it.

HD7990 at PCIe slot #1 and #5 (of 7) and it could work.
I didn't tested 3 VGA cards, it wouldn't go because not enough fresh air for cooling.
I have a Super Flower 2000W PSU.

The warning appeared just one time until now.
I guess because - maybe - I changed the jumper of the onboard VGA output 3 times (off, on, off - for tests) and the last time the jumper was very wobbly (and this is a €500 ASUS board).
I think I must repar it with a pliers and press together the contacts.


I'm still confused that the "Windows 8.1 Pro x64" DVD will be not recognized as 'bootable' source.
If I test the 'old' 'Windows 8.1 x64' DVD from my other J1900 PC - it will be recognized as 'bootable' and will install the OS.
What is the problem that the 'Pro' version of Windows 8.1 x64 don't want to install the OS?

I had contact with the online shop - they said opened software they don't take back (they said also, they registered the OS as I bought it. (If I buy an OS, they send Microsoft my address?) So they can't take back also. Is this all true?).
What? I payed €150 for a damaged DVD and that's all?

EDIT: I need the 'Pro' version because it have dual CPU support.

The PCIe riser don't work.
So I must use all HD7990 directly in the PCIe slots.
But then, just a paper can go between the VGA cards.
I installed a 3mm plastic between the VGA cards, to push them away from each other, nevertheless one fan of a VGA card had contact to the backplate of an other card and made noise.
OTOH, 4 HD7990 don't work (currently, or always with my mobo).
2 HD7990 could work, but... - it wouldn't be a 'Monster GPU Cruncher'. ;-)

AFAIK, each HD7990 have a PCIe 3.0 x16 plug.
So 2 HD7990 each CPU, 32 PCIe lanes used.

It looks like I have the v5304 BIOS installed.

Thanks for tips and hints (thanks also for PM :-) .
All the day I looked in BIOS what I could set, had set wrong, and so on...
I found no mistake.

Strange happened, I don't know maybe the BIOS is... I don't know...
Today, just 1 HD7990 installed, start, again a BIOS windows say something: 'fatal system error'.
Reboot and I see again the DOS screen.

What ever...

I got the idea, I test the 'old' Windows 8.1 x64 DVD of my J1900 PC.
And... - and... - it worked, Windows started to install. *confused*
So the Windows 8.1 Pro x64 DVD is broken?

BTW, I ordered 4* 'R9 FuryX' VGA cards.

If they are here, and I can't install the OS and/or something don't go like it should, I will never again build my own PC. *annoyed* ;-)

1 Xeon E5-2630v2 have 40 PCIe lanes - I have 2 installed.
»http://ark.intel.com/products/75790/Intel-Xeon-Processor-E5-2630-v2-15M-Cache-2_60-GHz«


I'm more confused about, that I can't install Windows... ;-)


Ohhh... - all the days for nothing.

The dream is over - It remains just a dream...

In short: it don't work.

I installed all like it should, with PCIe riser,
the screen connected to onboard VGA output or to the DVI output of the first VGA card, both times the screen say 'no signal'.

I took all PCIe riser away and connected all the VGA cards to the PCIe slots directly, after switch on I see a 'BIOS screen' (not at the onboard VGA (here still no signal), DVI output of the first VGA card):
»PCI out of resources condition:

Error: Insufficient PCIe Resources Detected!!!

System is running with Insufficient PCI Resources!
In order to display this message some
PCI devices were set to disabled state!
It is strongly recomended to Power Off the system
and remove some PCI/PCI Express cards from the system!
To continue booting, proceed to 'Save and Exit' Menu Option
and select Boot Device or 'Discard Changes and Exit'.

Warning: If you choose to continue booting some Operating
System might not be able to complete boot correctly!
«

This means 4 HD7990 VGA cards (4*2GPUs=8GPUs) are too much for the ASUS Z9PE-D8 WS board??

I took 2 VGA cards away, just 2 VGA cards installed, PCIe slot #1 and #5, after a few seconds I see something like:
'Insert bootable source and press then any key'.

I have no optical device installed via SATA or something.
Just an USB DVD writer/reader.
In BIOS correct recognized.
In the DVD device the Win8.1 Pro x64 DVD.

(I selected the boot order, 1st HDD 2nd USB DVD and then 1st USB DVD 2nd HDD, in both ways the PC don't see the Windows DVD and say 'insert bootable source'.)

I can't install Windows??

I have the 1st BIOS version which support Xeon E5-26**v2 CPUs.
Maybe a BIOS update and all 4 HD7990 could work? Or this have nothing to do with the BIOS versions?

Not a good day... :-(


BTW, maybe I'll (forced to) go with 4* R9FuryX or GTX980Ti (if I would like to have performance/RAC like 4 HD7990)...

If I look to the specs, 2*GTX970=1*GTX980Ti (performance/SETI RAC)?

If NV, then maybe 4* EVGA GTX980TiSC (max. (or other OC series)) or EVGA GTX970FTW+ (at least).

Unfortunately not.

A few cables I need to mod & connect.

Then I will make a test run, if the PCIe riser work or not.
I found someone in the web, he used the same PCIe riser and the VGA cards didn't start.
If they start, if I can install Windows, if the SETI/AP apps run fine, I will switch off and finish the build.

I modded also the Thermaltake Core X9 case.
Now it's just the frame, everything I could take away I took away (inside and outside).
Later 7 fans on the left, 7 fans on the right which push air in, and 8 fans on the top which take the air out. Maybe more fans. The monster will make much hot air...
(all 120mm 1900RPM fans)

Latest to the SETI@home-Wow!-Event 2015 he's ready to Rock 'n Roll (if everything will go like it should go (see above)). :-)

All objections regarding its usage come from quite few SETI forums members and all based on its possible influence on CreditNew credit awarding scheme that has quite a little connection with things that can be considered as positive for the SETI@home project. It was discussed many times already, I don't see any reason to start new round. Just don't deceive public with from where roots of buzz grow.

You use the rescheduler and you know it will screw up CreditNew.
Wrong granted Credits for the (your) results.

But, your wingmen can't do anything against it, they must accept it that they get wrong Credits, because you use a rescheduler tool.

You don't need to answer... - it's just an ascertainment. ;-)

Yeah, there seems to be more in play than just the GPU, as when wider distribution was tried some reported extreme problems (with anger). Maybe the next generation of OpenCL and Cuda applications will handle these more to everyone's liking.

Yes, as in VLARS take more GPU resources, so, all those cards set to run more than 1 or 2 at a time would start choking...and then the complaints would roll in.

ATI cards receive VLARs at Beta, as do nVidias. Neither receive VLARs on Main.

For 2 or 3 years someone said to me that the ATI/AMD VGA cards (Windows) get .vlar WUs (@ SETI-Main)...

When that was changed?

The developer of this rescheduler tool took his tool offline, because of CreditNew.

A rescheduler tool screw up the correct calculation of the Credits/results (your own - and your wingmen get the same wrong Credits granted).
The SETI server think e.g. it's calculated on CPU (as it is marked online), but after rescheduling it was calculated on GPU. The SETI server does not notice it and grant wrong (not accurate) Credits.

If I understood »this article« correct, then the left and right (yellow + black) cables of a PCIe 6pin connector can deliver 75W (just 4 pins).
I'm right?
So then the above mentioned mod should work.
