MSI Z87-G43 PCI performance fails compared to similar ASUS

[Bud Weiser]

As far as I know, there are at least three mayor versions of the big cards:

First generation 15 DSP cards with slow ULLI
Second generation 15 DSP cards with fast ULLI
"Second" generation 14 DSP cards with fast ULLI

I think that´s correct.
My 15 DSP card ran in a Intel P4, ASUS P4T-E and 2GB RAMBUS, Win XP and SCOPE 4 (4.5) w/ ULLI @7ms/44.1K, no clicks and pops, Reaper 3.x and several VST/VSTi as also Reason 4.

So, I´d say that´s a 15DSP 2nd gen card.
I was able to load the DSPs ~95% !

It will run again soon w/ SCOPE 5.1 in my old Intel D945 dual core socket 775 ASUS board machine when I have a new build for XITE-1.

This first generation 15 scope (confirmed right now, from some shots I sent yesterday) worked pretty good with my MB slot 1156, for this reason I had some difficulties to believe that with this new system it was working bad.
I think the overall performance is a mixture of scope and Motherboard together.
So the first generation is not useless with older legacy PCI slots, I guess.
Of course you cannot expect tons of Materverbs, but at least the ability of open several others effects and synths, yes.

Yeeeeeeah!

Tried Scope 6 DSP (second gen) as main I/O + Scope Pro 15 DSP (first gen) and all works flawless!!!
I can reach 13 Masterverbs before the infamous warning, or 12 Masterverbs nad several synths (until the end of DSP power).
I'm very very happy of this

Problem solved, I need just a 6 DSP or 3 DSP board to put as main I/O card.

So: use your first generation always as DSP power addon, not as I/O

It is great, that it worked. I am pretty sure that only one card actually communicates with the PCI-bus. And the other card(s) only communicate with the PCI-bus through the 'mastercard'.

[erminardi]

and all of this with a STDM cable only instead of the two required for connect a Scope and Scope Pro!
I haven't a second cable...

Hi there,
I'm writing this post to share my experience with this following setup:

Motherboard: MSI Z87-G43
RAM: 4+8 GB kingston HyperX 1600
CPU: Intel Haswell Core i7-4770S - socket 1150
HDD system: SSD kingston 120GB
HDD samples: WD caviar green 1TB
PSU: Fanless PSU 500W
Heatsink: Nofan CR-80EH Copper IcePipe 80W Fanless CPU Cooler
OS: windows 7 pro x64 (last update)
Internet: absolutely not!!! (and no antivirus installed)
SCOPE SYSTEM: PCI based: Scope pro 14 DPS + Scope Home 3 DSP

regarding the pure CPU power and overall features this setup is a bomb, expecially:

- SSD (OS boot and operative in 7-10 seconds)
- CPU/ram power: I cannot say exactly how may VST are allowed, tons.
- stability: never had a crash
- silence: it is like to switch on a DVD player, the Caviar HDD is the only rotating device that makes very low noises.

regarding the Scope compatibility:
this is the main problem!
I bought this MB basing on PlanetZ advices that report good results with Z87 chipset and 1150 socket.
But sadly I discovered that this Motherboard features only 2-3 masterverbs, or a Minimax and a couple of effects, before starting to complain about PCI overflow.

I tried to clean PCI contacts, to change scope PCI slots, to use only one board, to increase PCI latency timer in BIOS, but nothing was resolutive.

I fear that I have to buy an Asus ASUS H87-PLUS (chazbloke said that it reaches 10 MAsterverbs) or an ASUS Z87C (Dante said that it reaches 10 Masterverbs).
But I find this very very strange because this ASUS Z87c seems exactly the same of my MSI model, same chipsets, same layout...
Maybe differnt implemetation and better drivers?
Who knows.

Any other similar experience/advice before buy another MB (sigh)?

Thanks in advance.

it's a problem with your chipset.
chose a B75 or B77 compatible with "NATIVE PCI".
in the native pci motherboard there's no chip between the pci bus and the processor.
it is this chip causing pci overflow.

you also had to configure your cset.ini.
put the card in the computer in this order:(with 1 stdm câble plug the two cards)
pci 1: scope sp
pci 2: luna

add this line in the cset .ini and save:
[Host-Config]
Numboards=2
Board0=Host

[Board0]
Boardid=1


[Board1]
Boardid=0

well, yes, the chip, but no.
the chip is a controller that used to be part of the chipset.
socket 1150 motherboards also have a seperate controller that is not native to the chipset and they work. quality control hasn't been real good, however. i've seen three bad 1150 ASUS motherboards. Z87 boards DO generally work.

the seperate controller chip is just a sign that the PCI slot is slowly disappearing. the socket 1155 motherboards were the first with the new spec, so it's not that big of a surprise that they generally don't work. there isn't anything bad about 3rd party controller chips when they are made correctly.

My problem (now solved) was the Scope Pro first generation... with a very bad PCI performance.
I just put the Luna II as master and everything went good.
