PCIe 2.0 Expansion slot / Available lanes for 1.0 card

OK , Heres the question :
In the PCIe 2.0 expansion slot { Slot number 2 } , Can I put an X8 1.0 Raid card in there ? and how many lanes will slot 2 support at 1.0 ?
I know that it is backward compatible , but , it NEVER states how many lanes it will support in that slot.
Is it like slots 3 & 4 ? and goes down to x4 or even x1 ??
I called Apple today and spoke with 3 different tech guys and no one REALLY knows !!
They sent me some files to read , but none of them specifically states that a x8 1.0 PCIe card will be given an 8 lane throughput in slot 2 !!
So , how about guys ? What's the true and accurate answer here ?

In the PCIe 2.0 expansion slot { Slot number 2 } , Can I put an X8 1.0 Raid card in there ? and how many lanes will slot 2 support at 1.0 ?
The answer is yes. An 8x PCIe 1.0 card will work in slot 2. It will perform the same as if the card was installed in an 8x PCIe 1.0 slot.
This use to apply to all PCIe 1.0 cards. However, when Apple released Mac Pro EFI Firmware Update 1.3 it caused 1x PCIe 1.0 SATA host cards that utilize the Silicon Image 3132 chip to no longer work in slot 2. These cards will still work in slot 3 and 4.
Unfortunately, users cannot retreat to the Mac Pro EFI 1.2 firmware if 1.3 has already been installed.

How to install a PCI card in my HP 110-335t expansion slot?

The HP 110-335t desktop comes with one expansion slot, per the product spec. Right? How do I open up the box and install a PCI card?
This question was solved.

Hi,
Review this HP posted information.
You can use the PCI-E mini-slot for a wireless LAN card. Contct HP Support or Sales and get a recommendation. You will still need to configure an antenna.

MSI 890FXA-GD70 - Can you use all 6 PCI Express expansion slots at once?

Hey all,
I'm trying to figure out if it's possible to use all 6 PCI Express expansion slots on the motherboard (the 5 Full x16 slot and the 1 x1 slot) at the same time? I know I'd lose the capability for x16 bandwidth but does using any of the slots automatically disable any of the other slots? I have 6 single wide x1 PCI express cards I want to use at the same time and they do not all seem to be getting recognized by the OS (W7 x64).
Specs on the machine are:
890FXA-GD70 Motherboard - BIOS 1.9
AMD Sempron 145 CPU
4 GB DDR3 Kingston RAM
WD 160 GB Blue SATA HD
Win7 x64
Thanks!

What cards are they?
By not recognised is mean, not detected? driver conflict?

• 5 PCI Express 2.0 x16 slots
- PCI_E1 supports up to PCIE x16 speed (when PCI_E3 is empty)
- PCI_E5 supports up to PCIE x16 speed (when PCI_E6 is empty)
- If you want to install two graphics cards, please use PCI_E1 & PCI_E5 slots
- PCI_E3 & PCI_E6 support up to PCIE x8 speed
- If you want to install four expansion cards into PCI_E1, E3, E5 & E6 slots, these four PCIE x 16 lanes will auto arrange from x16/ x0/ x16/ x0 to x8/ x8/ x8/ x8
- PCI_E4 supports up to PCIE x4 speed
All PCI-E slots can be filled at the same time with no problem.
They will run at x8,x8,x4,x8,x8
The question mark is the small PCI-E x1 slot.
It's not clear if will affect others or will be disabled, or will work fine with x1 speeds as adverted.
What hapends if you fill 5x of those cards into the five of the PCI-E slots, except the small PCI-E x1 slot?

No ISA slot available in PC. How can I use PCI-85 Modbus Plus card with Lookout?

My application is to communicate with two Modicon PLCs using Modicon's ModBus Plus (PCI based PCI-85) network card inside my PC, and using Lookout as an SCADA software. Since there is no ISA slot available in new PCs, I can not use Modicon's ISA-85 Modbus Plus networc card. But Lookout does not support PCI based PCI-85 card, how can I use PCI-85 card then, with Lookout? Why doesn't Lookout support it? I asked the following question from from the Modicon's representative about it:
If I purchase Modbus Plus Driver Suite CD (SWMXDS001, 05, or 10 etc),will I be able to use Lookout SCADA software (by the way, it supports standard MB+ prtocol) for my application? If yes, can I use any version of an
y of the ISA, PCI, or PCMCIA based MB+ card?
His answer was:
The Modbus Plus Driver Suite will talk to any version of card, PCMCIA, ISA, and PCI. The question now is will the SCADA package you are
planning on using be able to talk to the Modbus Plus Driver Suite? You must contact National Instruments and ask them if they support Modbus Plus, and if
they used the MB+ system developement kit to develop their product. Or if they wrote their own MB+ drivers, do they work with Modicon hardware?

Hi,
currently Lookout does not support the PCI-85 card. The only card supported for Modbus Plus is SA-85. Please see for further information:
Where can I Find Drivers for Communicating to PLCs, RTUs, and Other Industrial Hardware?

PCI Card Slot - Wireless LAN Card Problems - Help!

Help.
I'm having problems getting my board to recognize both:
Linksys WMP11 Wireless LAN card; and
Netgear WG311T Wireless LAN card
(returned the Linksys card, but the Netgear card had the same problem).
Neither card is being picked up by Windows (XP Home), although both the "power" and "link" LED lights up when inserted. I've tried every PCI slot, same issue. Nothing shows up in the device manager, and no new hardware is detected. The Netgear software tells me that the card has not been installed.
Am left thinking I need to RMA the board. Any suggestions woudl be much appreciated.

My roommate has a similar setup as you and I am having the same problem getting a pci wifi card to work in the machine. I have tried both a Linksys WMP54G and a Netgear WG311. Both cards will scan for networks bit will never connect my router (Linksys WRT54G). Just to get them to recognise the network, I have to turn off WEP, and turn on ESSID broadcast. Both of these cards work prefect in other computers. I know it not a signal problem because I can take my laptop and set it in the same location and it gets excellent signal.
I have tried changing slots in the machine, the wifi cards were the only PCI cards in the machine and an GeForce 6800 GT in the AGP slot. I have no idea what the problem could be. But I'm leaning towards the mobo at this point.

PCI Express Expansion Slots

I noticed that the Mac Pro offers 3 extra expansions slots for PCI Express graphics cards. How is it possible to SLI three graphics cards with no nForce MCP? Are the other slots even usable and how can you combine four graphics cards with no Crossfire or SLI?

SLI and Crossfire are not supported at this time.
The possibility to run more monitors is there with the extra slots, but not to combine video cards for faster frame rates on a one monitor.
It's not Apple's fault, it's the limited capabilities in the Xeon chipset supposedly, not all slots can be 16x. A pair can be 8x though.
I lost the link where Ars Tech explains it.

H530 - Variant: 57324689 PCI Express expansion slot ?

Hi there.
I can´t figure out if the expansion slot on board is a "real" pci express, or if perhaps it is something different..
Can you pleace help me ?
I need to fit a Firewire pci-express card or adapter of some sort to my computer...
And the cheapest i have found is a firewire pci express card...
The reason i ask, is that i can see H530 type computers with 3 pci-express slots, but my computer has only one ?!?
And also i see something about that slot is only for some kind of wan card ?!?
So i am a little confused...
Pleace help me
Kind Regards
Peter

hi pshdo,
Welcome to Lenovo Community Forums!
Can you take a photo of your mainboard slots.
the reason is, Your system board might be different from this photo i found for H530,
but if it is the same then, here it is
Your system has 1 PCIE x16 most likely for GPU or Graphics card.
Then you have this three small PCIE x1.
check if that firewire adapter supports PCIE x1 then you good to go,
Hope this helps

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.

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.

Firewire pci card in B&W Expansion slot #1?

I am using my Blue & White G3 as a server, including a role as backup server to an external firewire hard drive which is connected to a firewire PCI card in expansion slot 3.
The first expansion slot on the B&W runs at 66mhz, the other three at 33mhz. Since I run the server headless (access through Remote Desktop), I do not need to have the video card in slot one but could put it in another, slower, slot.
My questions are:
1.) Can I put the firewire PCI card in slot one and
2.) Will I get higher throughput?
Thanks,
Rich
G5 Dual 2.0 Mac OS X (10.4.3)

FireWire 400 is theoretically capable of 400 MegaBits/sec. At 8 bits per byte, thats a theoretical maximum throughput of 50 MegaBytes a second.
A 10,000 RPM drive can source a single burst of data off the platters at about 50 MegaBytes a second. Write bursts can be slightly faster, because the data goes in the cache, but you have to write it to the platters eventually.
The 33 MHz slots are talking multiple bytes at once, so there effective speed should be quite a bit higher. I have seen a rumor here that bugs in the firmware limit the 33 MHz slots to a mere 53 MegaBytes/ second.
My assessment is: everything is topping out around 50 MegaBytes a second. Unless you are using a 15,000 RPM drive in the FireWire enclosure, you do not need to do anything extraordinary. Connect it in the usual way and it should do fine. The extra theoretical speed from the 66 MHz slot is unlikely to be seen in daily use.

Why available Lan Host not showing up in the DHCP Leased Client table for RV180

I just purchased the RV180 and am puzzled as to why lan host with ip address of 192.168.1.102 not showing up in the DHCP leased clients list.
I have 4 static ip addresses with the last 3 digits ending in 101, 102,103 and 200 listed in the static DHCP and available local network list, but 102 is not in the DHCP leased clients list. The other 3: 101,103 and 200 are.
Should it not be there also?

Thanks Marty,
There is nothing different about 102 than the other hosts.
I did talk to tech support at Cisco this morning and I was told that I should not use the static DHCP under Networking LAN. Instead, I should set the static IP at the device level.
So under Static DHCP, the list is blank, but the IP address will show up under Available LAN Hosts and listed as Static as Type.
I thought this is a bit strange since it is Static DHCP and should be under Static DHCP (?)

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

Windows 7 - Driver Availability Chart For Creative Products is nearly useless

<span class="text">[url="http://support.creative.com/kb/showarticle.aspx?sid=605">Windows 7 - Driver Availability Chart For Creative Products[/url] is outdated Windows pre-release drivers (at least for the Audigy SB0090 series) back from July. This appear to be revamped Vista drivers that are not usable for W7 RTM. MS made changes to W7 where most Vista drivers do not work properly any more.
When I try to install the drivers through the installer I get the incompatibility error and the installer quits, then I get the failed install pop-up for W7.
What I would like to know is when Creative plans on releasing drivers that work with W7 RTM? Llinking drivers that worked for W7 RC is not helping and really should be removed.
I have used Creative sound cards since just before the SB6 came out. I have been a loyal Creative customer from early on. But if Creative can not deali'ver a fully working driver suit for my sound card by the end of the month (November) I would appreciate knowing so I can start looking for another a replacement, which won't be a Creative product.
Even though my last 3 MBs have had good built-in sound, I have went out and bought Creative sound cards because I wanted the best, which Creative has previously provided.
I need to upgrade my MB so I have put of buying a new sound card until I do. But if I'm forced to buy a new sound card because Creative says it will provide drivers that work with W7 RTM and for what ever reason can not do so, I will not be buying another Creative product.
I maintain 4 PCs of my own so that will be 4 cards bought from a competitor since Creative has completely dropped the ball. All major component manufacturers have been able to release stable drivers at the same time as W7 RTM release , or within days after release. Why hasn't Creative been able to do so? Creative was able to release suitable drivers for RC in a timely fashion, what happened with W7 RTM? Did they recently fire all the programs and techs?
Please do not link useless info. Please find out what is going on and tell the powers-that-be at Creative they have some really upset customers and ask them to tell us what is happening here. Tell them we would like to know when Creative plans on releasing drivers for W7 RTM so we can make the decision to wait it out or buy replacements.

Again, yes Device Manager has no problem detecting the card and W7 has no problem loading the default Window drivers for it.
Since I had to replace my TV Tuner Card, I used Device Manager to remove it and my Audigy card and then shut the PC down. My new TV Tuner Card is a PCI-E x so I installed it in an open slot and move the Audigy to the PCI slot where the old TV Tuner Card was.
When I started my PC again, W7 detected the Audigy card and loaded the defeult drivers. I again tried to use the installer and had the same error.
The sound works, but I only have basic Windows functions/controls.
It is most definately not a hardware issue.
The online auto update detects it, just the installer does not detect it.
I am currently awaiting a response from CS now. Of course the problem there is that you have to wait/respond, wait/respond, wait/respond just to cover the same ground that has been gone over a hundrd times already.
I put every step I have done in the email. As usual, it was a waste to type because you are asked questions already answered and to preform steps already done.
It would be nice if CS would realize that some of us are only contacting CS because we have already done all the standard steps without success and now need to move onto the advanced ste

Expansion Slot Utility not working -- How to fix / Get a fresh copy?

I want to configure my PCIe slots to 8x 8x 1x 8x...
The reason for this is because I'm fitting an ATi X1900 with a passive cooler (Noise!), and it won't fit in the double-height slot.
All the info suggests running 8x v. 16x will make no difference: http://www.barefeats.com/quad14.html
However, my Expansion Slot Utility won't run. It worked fine the first time, when I looked at it, but now -- no go.
The 'Don't Show This Utility Again' button was definitely NOT checked.
I don't want to have to re-install the whole OS just to get a working ESU...can I download a fresh one from anywhere?

I DID read your post:
Hatter...you can't run it from the Utilities folder...it won't work. I tried. Only running it from the CoreServices folder worked.
So is that now false?
I launched the copy that I have that I put in /Utilities and confirmed that it will launch and works fine.
Next, I checked and saw that there was an option when you launch it to "not show again" in the window.
There must be something wrong on your end. So don't tell me I didn't read your post (or Ned's) and I did see that you had it open in back. Couldn't tab to it.
But.... it sounded like... you tried to confirm and re-launch it again. At least that is what I would do, to test whether it can be launced, rather than to say "can't be launched except from CoreServices" which I know to be FALSE.
No where did you say, "okay, it launches now from Utilities."
So be clear - it ain't easy.

Early model Mac Pro's Expansion Slot Utility not working with 10.5.6 update

I'm reading that the 10.5.6 update may have crippled the Expansion Slot Utility for early Mac Pros.
I have a 2.66 Mac Pro, and I just installed a Kona 3 card in slot 3. Already had an ATI 1900xt in slot 1. However, the Expansion Slot Utility program detects only the ATI Card.
However, in System Preferences - the PCI column clearly shows slots 1 & 3 are occupied and with drivers installed for the respective boards... The Kona card works for video preview (further indicating that it's installed correctly - but the Expansion Slot Utility is broken), but I understand that the Kona card is operating at the 1x speed, thus crippling it...
Apple please fix this... Any administrators or someone in the loop care to elaborate please...
Thanks,
Lonnie

So, here's the deal. Running the Expansion Slot Utility still works for our model of computer - it just doesn't register correctly within the program. This is only a cosmetic flaw. I've confirmed this with AJA and in System Prefs under PCI columns.
Also, AJA recommends 4Lane, slot 3. There it lies. Furthermore slot 4 concerns me - too close to drive bays for proper air circulation and the propensity for over heating.
The main issue of not sleeping has been answered by AJA. Their Kona 3 card does not support sleep.
Guess I'll be turning my computer off instead of sleeping it after hours - no biggee...
