P7N Diamond, whcih PCIe slot to use for SLI?

I would like to use both PCIe x1 slots, which means slots PCIe2 and PCIe3.
But if is insert the bouble width 8800GTS card in PCIe1, which is the first PCIe 2 x16, then I will cover the first PCIe x1 slot.
Anybody have any experience in using the PCI e 2 x16 slot called PCIe4? and then used the PCIe5 as the SLI card slot?
Thanks Michael

I have personally found a full 5% increase in sli performance by using blue/blue rather than one blue and one white. I don't know if it's just me or if this difference is universal.
I second that...
my advice : put both of your graphic cards in 16x blue slots, your X-Fi in the free PCI-e 1x slot you should see between your graphic cards, and put your TV Tuner in the yellow slot. everything should be working ine that way

Upgrading Mac Pro (2009) from to NVIDIA Quadro 4000, what PCI slot to use ?

I am upgrading my Mac Pro (2009) from the Nvidia GT120 (stock) to the Nvidia Quadro 4000 for Mac. The GT120 was installed in the PCI Slot #1 and I would like to install the Nvidia Quadro 4000 in the PCI Slot #2, that way the Fan in the Graphics Card (Quadro 4000) will have better air circulation, is there any limitation or recommendation regarding the PCI slot to use ?, thanks a lot

I have an early Mac Pro 3,1.
The user manual I downloaded states:
Slot 1 PCI Express 2.0 16-lane
Slot 2 PCI Express 2.0 16-lane
So I'm assuming that means both slots 1 and 2 are the same and it doesn't matter which of my two graphics cards go in which slots?
Also, my second graphics card is a Quadro 4000 which is for Adobe Applications that use the CUDA engine. I don't have any monitors hooked up to it.

Can 1st and 3rd slots of X99S SLI Plus be used for SLI?

Can I use the 1st and 3rd full size PCI slots for SLI on the MSI Global X99S SLI PLUS mobo?
Specs:
* i7-5960X, intend to OC
* Corsair H100i cooling
* Corsair AX860i pu
* 32gig 2400 DDR4
* Samsung XP941 256GB Ultra M.2 PCIe
* 2x Gigabyte GTX 970 Gaming, intend to OC
I'd like to not put the 970's on top of each other when there's so much extra space - will i get PCIx16 if I use the 1st and 3rd full size slots? Any downside at all?

yeah its a shame, makes for a bad design if using sli on air imho, one card runs 20-25c hotter than the other :(
if I had known of this design problem i would have gone for a different board :(
can't understand MSI's reason for this?
not looking forward to the summer heat coming, might have to try water cooling (if there is room) but even that looks a tight fit?
has anyone run wwater cooling on the MSI GTX970 Gaming on these boards?

Does the MSI Z68-G43 G3 support 8/8 PCIe 2.0 lanes (for SLI/CF)

Hello,
The MSI webpage states
Quote
• 1 PCI Express gen3 x16 slot, 1 PCI Express gen2 x16 slot
• 2 PCI Express gen2 x1 slots
• 3 PCI slots, support 3.3V/ 5V PCI bus Interface
for the MSI Z68-G43 G3. It doesn't say whether the board can run the 16 PCIE 2.0 Lanes in 8/8 configuration. My current (Gigabyte P67A-D3-B3) board can only do 16/4, so I am considerung moving to this board for Crossfire. Does anyone know if 8/8 2.0 is possible with this board and a Sandy Bridge CPU?
Regards
chris

Quote from: RemusM on 27-September-14, 04:52:45
SLI is not possible on this board.
The PCI-E 2.0 slot is equipped with only 4 lanes.
http://www.msi.com/product/mb/Z68AG43_G3.html#hero-specification
PCI-E Gen : Gen3 (1x16), Gen2 (1x4)
Thanks for the help, Remus!
I am now looking to get a Z77A-GD55 instead. It is specified as PCI-E Gen : Gen3 (16, 16), Gen2(4) so it should be fine (Sandy Bridge only reduces it to Gen2 (16, 16) instead of Gen3 (16, 16), right?).
They are somewhat hard to find, though, unlike the Z68A-GD65-G3 with Gen3 (16/0, 8/8) and Z68A-GD80-G3 with Gen3 (16/0, 8/8), Gen2 (1x4) . So I'll see what I can get.

PCIe Slots P55 GD-65

Does it matter which PCIe slot is used for single video card?
Board:P55 GD-65
Card: GTX 260

Quote
The manual for his board is a bit confusing on this matter.
Actually, it isn't. It (only) mentions the two possible operating modes: (x16/x0 and x8/x8 (bifurcated mode)). If you look at the specifications on the product page, the same is true:
http://eu.msi.com/index.php?func=prodmbspec&maincat_no=1&cat2_no=&cat3_no=&prod_no=1846
Quote
PCI-E Gen Gen2 (1x16, 1x8)
However, what the board specifications and the manual state is of secondary importance (even though there is nothing wrong with the information). The PCI-Express interface is provided by the processor alone and it is the design of the CPU that desides about the possible ways of lane assignment.
We had this discussion before, so let me just quote the relevant information I already posted there:
https://forum-en.msi.com/index.php?topic=137305.msg1036301#msg1036301
Quote
However, what you guys actually have to look at are what Intel has to say about this in the Processor Specifications:
http://download.intel.com/design/processor/datashts/322164.pdf
Have a look at page 27: "PCI Express* Bifurcated Mode":
Quote
When bifurcated, the signals which had previously been assigned to lanes 15:8 of the
single x16 Primary port are reassigned to lanes 7:0 of the x8 Secondary port.
The two PCI-Express Ports are tied directly to the processor. Of course, both are x16 ports in size, but not in terms of bandwidth. From the point of view of the processor, the primary port is a true x16 port (size & bandwidth). However, the secondary port is only a x8 port (bandwidth), that is why Intel labels it as "x8 Secondary port". There is no way the secondary port will ever be able to get more than x8 lanes assigned to it.
This has nothing to do with the mainboard, but with how the CPU manages the bifurcation of the PCI-E lanes. There are only 16 lines of which only 8 can be reassigned to the secondary port.
The CPU's PCI-Express switching logic is not designed to re-assign all x16 lanes to the secondary port. There is only one switch available: x16/x0 or x8/x8. No other operating modes are possible. That means, whenever there is a device in the secondary port, it will get x8 lanes or none at all.
Quote
nothing was mentioned about the CPU limitation.
The CPU hosts the PCI-Express controller. That means the whole lane assignment logic (naturally) depends primarely on the CPU.
Quote
It would be interesting to see & verify what the bandwidth actually reads when just one card is placed in the PCI-E5 slot only.
It will get x8 lanes assigned to it, not one more.
Quote
We know it certainly can't be 'x0' with one card, but if not using two cards, the 'Auto Arrange' to force x8 in the PCI-E5 slot runs x8 regardless?
Yep.
Quote
The CPU as you mentioned Jack, is the only limiting factor then? Otherwise the board itself could run the PCI-E5 at x16?
The CPU is the deciding factor here. I would not call it a "limiting" factor. The board itself cannot to anything in this matter because its chipset does not provide a PCI-E interface to begin with (well, at least not the kind we need).

P7N Diamond, put a single GPU in either blue PCI-E slot?

I thought I had seen that when running only one graphics card, you were supposed to use the top pcie slot, or you would get better performance from doing so, but I can find no mention of that now. I notice that I can get better airflow moving my 8800GT down to the lower blue slot. Is there any reason not to do that?

Quote from: Jack t.N. on 15-November-09, 08:48:11
On some boards (P45 Platinum for example) using the secondary PCIE-Slot will result in reduced bandwith (x8 instead of x16). That is the main reason. On other system configurations, the second PCI-E Slot is only for SLI Mode and putting the single video card in the secondary slot will make the system halt when it is trying to initialize the video adapter. These are the reasons why on those systems it is recommened to use the primary PCI-E Slot.
In your case everything looks fine. There is no issue here.
Cool thanks

HELP! - Voltages for Overclocking Q9450 on the MSI P7N Diamond (780i chipset)

Hey. I fully understand the settings as far as frequencies go, but am a total voltage newb. No matter what I do I cant seem to get a stable vista load up with my voltage settings.
Please help me by providing suggested voltage settings for my hardware.
CPU - Intel Core2Quad Q9450

adjusting gtl ref. voltages isn't very difficult, but it is probably best to learn the basics first.
So, basically, increase the fsb a little. So, for example, from 1333 to 1400. See if it's stable, if it isn't try bumping up vcore one notch and try again. If not try Northbridge. Then later move on to stuff like the fsb term.
Test stability using prime95, there is a 64-bit multi-core aware version floating around somewhere. Try the ftp server linked to in the "hot use prime95" sticky on here.
Tbh with your OC you shouldn't need to touch any other voltages, or really use the gtl ref settings. What exactly is "sufficient" cooling though? Stock?
*EDIT: on a side note, just so you don't think I'm deliberately being awkward not telling you specific voltages, they wouldn't do you any good. Every cpu/mobo can handle different freq. at different voltages. Also, use cpu-z to check on your actual voltage and make sure you don't raise it beyond 1.3625 (I think that's right, it's 1.36something anyway)
Thanks for the tips. The reason I wanted to jump straight to FSB 1600 is because the MSI p7n is really picky and only likes 1:1 ratios.
My "sufficient cooling" is an aftermarket heatsink, high performance thermal paste, and MASSIVE airflow through my case. If you want specifics, its the Scythe Zipzang
Quote from: AaronYuri on 08-October-08, 09:05:16
CPU Voltage - No one can tell you this.
NB voltage - Depends on what frequency you want
SB voltage - What's your HDD setup?
NB Memory reference voltage - Auto
DIMM memory reference voltage - Auto
Memory terminator voltage - Auto
CPU GTL reference voltage - Depends on speed and other voltages
NB GTL reference voltage - Same as above
FSB terminator voltage - Depends on CPU voltage and CPU/FSB clock speed
SB sleep mode voltage - Auto
PCI Expander PLL voltage - Auto
My recommendation is do some reading. Guessing leads to dead hardware.
6GBs smells like mixing modules... Or do you have 3 modules?
First of all, I already stated the frequencies that I wanted in the top post, and fairly clearly at that.
CPU shouldnt be too hard to figure out, as there are very few to choose from. I'll try to get back to you on that one
I have 5, 7200rpm SATA 3.0 drives. It sometimes runs with only 4, as one is a hot swap.
My ram IS mixed, unfortunately. I'm using 2x 1gig sticks, and 2x 2gig sticks. However, both sets have heatsinks, and are rated at 800mhz, 4-4-4-12, 2t, timings. (2.1v)
I AM running them in dual channel.
If this helps you suggest voltages please do, If not, then I will just have to start trying using nihilkrist's suggestions.

Best PCI slot for soundc

Hi, I have Sound Blaster Audigy 4.
I have 5 PCI slots and all of them are free. Does it matter, what slot I put the Audigy 4 in?
Are there any performance differences between the PCI slots?

If you do not have SATA HD's in use and/or RAID set up then you can disable those controllers and put your sound card into PCI slot 3.
The other 2 options to put your card into are
- slot 2 which is shared with your onboard NIC (disable NIC on Device Manager when you play 'heavy' games. You can also change the PCI latench for nic to 0 and increase PCI latency for sound card to 64 or 28 (link to DL PCI Latency tool can be found if you search this forum)
- slot 4 which is shared with some 'unknown' controller/device/other action ?
For the IRQ 5 question; you find explanation for this if you searcg for terms StandardPC and ACPI.

PCIe cards useful for editing capabilities?

Other than cards used to add RAID or additional hard drives, are there any other PCIe cards people find useful for video editing or effects work? The reason I ask – I am considering two different motherboards for my PC upgrade to i7-4770K. One will effectively have no free PCIe slots when the build is done, while the other will have one free PCIe slot (an x4). I am not including the two secondary x16 sized slots on these boards in my count, because they cannibalize the primary video card slot, so I would rather not use them.
Anyway, currently I don’t use any additional PCIe cards for editing. So I am not sure if I should care if there are any extra empty PCIe slots available.

Thanks for the suggestions. Also, I wonder how often Firewire is used these days? I have some older family videos on tapes, recorded digitially and accessible via Firewire, from a port on the camcorder. So if I get a board without Firewire, looks like I would need to install a Firewire card into a PCIe slot, if I wanted to edit those tapes. Otherwise, I don't see as many products today using Firewire.

I need a PCI ethernet card driver for my Performa 6360...

Roughly a week ago, I decided to add yet another one of my classic Macs to my LAN, a classic gaming LAN of sorts, with that mac being a Performa 6360. With it's single empty (at the time) PCI slot, the solution for an ethernet card for the system was basically screaming at me. Unfortunately, I went to my local electronics store with the assumption that PCI ethernet cards are fairly generic devices that should work in nearly everything without a problem. That turned out not to be the case. Once I finally aquired the time to install it, the card itself appeared to work, with the outer LEDs indicating network activity and a 100mbps network speed, however, when I went into the Appletalk or TCP/IP control panels, I came to the terrible realization that I needed a driver. The included CD was, much to my dismay, Windows only, Google searches haven't been much help, and worst of all, I seem to have misplaced my reciept. The "card" I keep mentioning is a Linksys LNE100TX version 5.1. Here is what is shown in the apple system profiler:
==============================
PCI Slot
Card type: ethernet
Card name: pci1317,574
Card model: -1
Card Rom #: Not available
Card Revision: 17
Card Vendor ID: 1317
==============================
What I am wondering is where I could find a driver for this card, and if that answer is "nowhere", is there any way I could get this card functioning under Mac OS 8.1? Any help would be greatly appreciated. Thanks.

Well the good news is there was one,
http://www.welovemacs.com/net-cs2-fe.html
finding one, is a good question. Oddly enough the link you posted to the 10T version is the same company as above.
Yes, I have tried searching a number of places for it, and haven't come up with much. Here is what a google shopping search pulled up (eBay came up empty), the first being "unavailable" for purchase once you add it to your shopping cart and the second costing only $150! I could easily buy a new (used) mac with the card installed in it for that much!
As for the PCI slot cards you are trying, keep in mind that you are trying to use current cards which didn't exist back in the day your Mac and OS were made...... I have Asante 10/100 PCI cards in some of that generation mac and they work fine but then they were supported by the OS.
Good point. Even back when I purchased it, the card seemed a bit of a long-shot to me, too. However, being on sale for $15, I thought, "why not at least try?". Unfortunately, I came up with the results above. However, you have given me a good idea. I realize from reading a few posts around here on the issue that it is a good idea to keep the pci slot of the computer open on this computer until there is a need to upgrade, let's say, for a graphics card. However, what if I have no future plans to add anything (as is currently)? Is it really that necessary that I keep the slot open? I'm sure it would be exponentially easier to find a card for that.
A long shot might be to try loading OS 9.0.4 and see if you get lucky as 8 is pretty old plus there's a part of me that wonders with such a slow bus and cpu that 100T is going to make a big difference.
Kevin
Thank you for the suggestion, but that's how I collected the information for the card in the first place. The Performa 6360 didn't seem to take the card, so I popped it in to my Beige G3 running Mac OS 9.2.2 and hoped it might work on that. Same problem, however, the Apple System Profiler is much more thorough on that OS, so I was able to acquire the card's information. The reason for the 100-BaseT Ethernet, again, is not solely based on that one computer; It's the fact that I would prefer the network to run at the faster speed and with four macs currently on it, with a few more modern ones such as the iBook G3 shown below, the speed is a nice thing to have.
So, on that note, any suggestions for a PCI equivalent? Has Apple ever made any? If so, where could I find them at a reasonable (Read: Not $150) price?
Thanks again.

NVidia 6800GT & PCI Slots - Keeping Things Cool & Copacetic

Hi Gang
Fully aware of heating issues, especially with Pre-Dual Core G5's and poorly cooled ATI Video Cards, I'm trying the following arrangment with my G5 2.0 Dual Core;
Need to take advantage of all PCI slots, but using NVidia 6800 GT, (with decent cooling), I put a FirmTek eSATA card in the middle 8X PCI slot, and Sonnet FW800 Cards above and below the FirmTek eSata card.
Took temperature reading of nVidia at start-up; 118 Degrees Fahrenheit. After about an hour, it went up to 129 Degrees Fahrenheit. Warm but not Hot to the touch. I'm optimistic ...
Why no 'internal' SATA Card approach? Because I don't like the drive rack arrangment which clearly obstructs the cooling fans. Got some great advice here from BD, and japamac. I think this was the way to go
Thanks for looking;

Hi-
Sounds like you are happy with your results?
Temps aren't bad at all, and now you have tons of external connections!
BTW, Nvidia used a Coolermaster heatsink/fan for the graphics card.
Nice to have a cooling specialist on the job.

P7N Diamond voltages

After watching some screenshots from ppl with same board showing CPUID Hardware monitor i have noticed that the VIN5 and VIN6 is higher than mine, and i would like to know if anyone of you know what it is for?=)
VIN5 is at 0.10-0.26V and VIN6 is at 0.17-0.38V
I am thinking that the motherboard does not get what it wants, another thing i have noticed is that the I12V thing in bios is not showing close to 12V at all, its alot lower.
I have no idea if it really matters but i still have alot problem with this computer and i dont want to buy anymore
hardware for testing =)

ok, for me it is not that i want to have the real voltages, i am just curious what you that have a working P7N Diamond board have, if you use the CPUID Hardware Monitor, maybe not accurate but i guess its not more accurate for you than it is for me etc, maybe just a waste of time=)
I have contacted both msi and gigabyte and waiting for their answer, have nothing better to do than trying to figure out things on my own =)
Probably wont get anywhere until tuesday or wednesday, it is just so frustrating when i cant solve my problems like sound crackling, monitor goes blank and graphic corruption on
DXVA(hardware accelerated) videos.
Could be that the motherboard/PSU does not supply enough power to the graphic card, could also be a bad driver but then all drivers are bad that i have tested,
seem to give me less crackling with a slower graphic card.
Got a new bios from msi, but then vista activation failed cause of new hardware, and it did not help me in anyway so flashed back to original.
Well i can always help others while waiting, learn alot of all this troubleshooting reading =)

Max Power consumption on PCI Slots

Hello again !
+I would really love to upgrade my Mac and am way out of my depth+ on the technical details
I have read in the Power Mac G5 users guide (P62) read that the :
Maximum power consumption for all 4 expansion slots (the three pci expansion cards and the AGP card should not exceed 90 watts (W).
+I cant seem to locate the wattage of the current and existing cards in-place :+
1] Slot 4 - Lacie usb 2 pci mac (NEC chipset) ?
2] AGP Slot - PowerMac G5 ATI Radeon 9600 128MB AGP8 Graphics card ?
+I am hoping to next add into the remaining expansion slots if possible :+
3] Slot 3 - Lacie FW 800 Card pci mac
+I am hoping to eventually add into the remaining expansion slot and the AGP8 slot if possible :+
4] MAC edition 256 MB NVIDA 6800 ULTRA Graphics card
+Would this potential combination possibly overload the logic board with power consumption ?+
Many thanks in advance for your much appreciated Mac expertise
Another nice shiny greens star awaits awarding !

Hi-
The Geforce 6800 Ultra Mac Edition takes the 8x AGP slot and covers one of the PCI slots.
Using a USB 2.0 PCI card and a FW800 controller card in the remaining two PCI slots should pose no problem.
As is, with the Radeon 9600, the two aforementioned PCI cards will be no problem.
A USB 2.0 card uses about 5w total.
A FW800 card uses 8w per port.
The table on This page shows the wattage of the graphics cards, and the remaining wattage for use in the PCI slots.
The 9600 leaves 75 watts to be used, and the 6800 allows 30 watts remaining.
You may note a discrepancy in the math, but there are both +12v and +5v power supplies to be considered.
Of primary concern is +12v.
The performance difference between the 9600 and the 6800 is not even comparable.
Personally, if necessary, I would forego a PCI card to use the Geforce card.
A powered FW800 repeater/hub can always be connected to the native FW800 port to add ports.

One PCI slot non-functional

I've got a Mac Pro, dual 2.66. Up until now, I've had 3 PCI slots in use (slot 1 - graphics, slot 2 - audio card, slot 4 - Firewire card) and have never used slot 3.
Yesterday I bought a new card and put it in slot 3, but it is unrecognized by System Profiler and by the drivers.
I spent a long time trying different combinations of cards in different slots, and finally came to the conclusion that slot 3 is entirely dead. No matter which card I put in the slot, System Profiler doesn't see it. (But the same card put into slot 2 or 4 works fine.)
I'm assuming that there's a hardware defect and there's nothing I can do but take it to the repair shop. Right? I thought I'd check here first just in case anyone could think of anything.
I did zap PRAM -- no change.

Is it a 1x or 4x card? and did you launch Expansion Slot Utility to check the slot settings?
It use to launch automatically in Tiger, but maybe not in Leopard.
System/LIbrary/CoreServices/
Try your FW card in #3 because it only needs 1x, and #4 is 8x by default unless it was changed.

P7N Diamond & 9600 GT SLI

Hi,
Small question.. Does the P7N Diamond support two 9600 GT (asus) in SLI mode?
Probably does, but could I get a confirmation on this, because in the manual of the P7N, dual cards in SLI are connected with 2 SLI bridges..and the 9600 GT only has room for one bridge....
Thanks in advance!

Thanks for the quick reply!
