SLI question

I just ordered some new parts to upgrade my rig abit
MSI K9N Diamond nForce 590 SLI
Athlon64 X2 Dual-Core 5600+ 2.8GHz 2x1MB
Corsair XMS2-6400 TWIN2X2048-6400C4 4-4-4-12 Xtreme 2x1024MB
Western Digital RaptorX Gamer WD1500AHFD 150GB 10000rpm 16MB cache S-ATA Clear Cover
Now I'm gona add those to the rig in my sig. and run it on an "PC-Power & Cooling Silencer750 QUAD +12v@60a +5v@30a +3.3v@24a" ones I get my hands on
a Lian-Li PC-V2100 Chassi since my Antec Performance One P180 wont fit that PSU without sacrificing HDD cooling :P
http://www.pcpower.com/products/viewproduct.php?show=S75Q <---- now I gotta say it's a real beauty
In addition to the upgrade above I'm verry tempted to buy another GFX card,
an Asus Extreme GeForce 8800GTS 640MB DDR3 TV-out HDTV DUAL DVI SLI-ready RETAIL PCI Express (same as I allready have)
Now my question is, how sensitive is the SLI mode, I know you have to have two Identical cards for it to work, but what if the two cards would vary
a little in features say one is from ASUS and the other MSI, but have the same GPU Core, would that cauze proplems or is it only the core itself that has to
be the same?

As long as the GPUs match, you can SLI them. (8800GTS with another 8800GTS) The manufacturer of the video card itself does not matter since they are made to Nvidia's standards.
Nvidia does have a caution on their website that the amount and type of memory in each video card should be the same for best results.

  • MSI Big Bang-XPower II SLI question

    Hello. I have a MSI Big Bang-XPower II with two cards in SLI. The cards are cooled using AIO water cooling brackets which makes them take up three slots each instead of two. I would like to add a third card with the same cooling. The manual says that for 3-way sli I should use slots 1,3 and 5 or 7 as they are all PCIe 3. My processor doesn't do PCIe 3 so I leave it in PCIe 2 mode. My question is, could I set up the SLI configuration using slots 1, 4 and 7? Would it run at 16/8/8 in pcie 2? Or would the 4th slot not be usable for sli?
    Thanks

    No, that is not possible. PCI_E4 is a gen2 slot limited to x4. SLI is disabled once a slot used is at less than 8 lanes. Follow the Multi GPU support table on 1-21 of your manual.

  • SLI questions

    Hi all.
    Im sorry if this has been asked already, if so please link the post.
    First of all i gonna buy a new Mac PRO. Really the only thing im intrested in is the hardware and i like to think i know the most of it. One headache i have thou is the SLI/ dual graphic card.
    here is the information given:
    *+Please note: The Mac Pro provides a total of four PCI Express expansion slots. If both the Mac Pro RAID Card and Fibre Channel card options are selected, up to two graphics cards can be installed.*
    Question 1:
    If i select the Mac Pro RAID Card and Fibre Channel card i can install 2 cards. Why can i then choose upp to 4 cards. doi read it wrong? Can i have 4 cards in SLI?
    Question 2:
    is 4 "256 mb card" better then one "1gb card"? if so how come? im not sure how it works with the array and sutch.
    and also is 2 "256mb card" better then 1 "512mb card" and if, how come?
    I can add that i work with movies/picture/games. How do dual/quatro graphic cards "as my question" apply here?
    and what i suppose everyone is asking. I will buy the mac beginning of 2009 and i will be mad if they release a new modell the week after i buy mine. Do we have any news about a updated mac pro?
    many thanx

    If I select the Mac Pro RAID card and Fibre Channel card I can install 2 cards. Why can I then choose up to 4 cards. Do I read it wrong? Can I have 4 cards in SLI?
    There are four PCI-e slots. If you have a RAID and fiber channel card installed, there would only be two slots left for graphics cards. If you don't have the RAID and fiber channel cards, you can install four graphics cards (but not more than two can be high power cards). SLI is not supported. More cards do not give more speed, just support for more displays.
    Is 4 "256 MB cards" better then one "1 GB card"? If so how come? Im not sure how it works with the array and such.
    Get four cards if you have seven or eight displays. For one or two displays, get one card.
    And also is 2 "256 MB cards" better then 1 "512 MB card" and if, how come?
    One card is better (unless you have more than two displays). With a single display, all the memory is available for that display. If you have two displays, the card's graphic processor can handle mirroring, or windows that span both displays, or are dragged to the second display. With two cards, that has to be handled by the Mac Pro CPUs, which would be slower.
    And what i suppose everyone is asking. I will buy the Mac beginning of 2009 and I will be mad if they release a new model the week after I buy mine. Do we have any news about an updated Mac Pro?
    Apple is waiting for you to buy your Mac Pro before they will announce any new models.

  • SLI questions about Z97 Gaming 7

    Greetings, folks!
    I've accidentally tore off the 2nd PCI-E slot on attempting to remove its VGA for maintenance. Don't ask me how! Somehow the VGA lock bracket hadn't worked as usual.
    Well, my question is: SLI works from 1st slot to the 3rd slot? I've not found any SLI bridges of that long, because the out-of-the-box bridge is too short. There's any risks on leaving the PCI-E tracks exposed? The board won't power on while they're touching themselves, but is working like a charm, sustaining my 4.6GHz i7 4790K.
    Thanks a lot, everybody. Peace.

    Should have 120mm long bridge online (I think it's enough?).

  • MSI GeForce GTX 780 SLI question.

    Hi,
    I wonder if my MSI GeForce GTX 780 Gaming OC is compatible with the MSI GeForce GTX 780 Lightning LE in SLI?
    Thanks!
    BR, Tobias

    as long as both cards are using the same GPU (GTX 780 GK110) and they both have the same amount of VRAM (EG: 3GB+3GB) then they will be able to be used in SLI as long as your PSU can power both of them!
    you can use SLI even with different manufacturers cards so long as its the same spec (GPU) as the other and the VRAM frame buffers match each other as both need the same amount!

  • MSI Gaming Motherboards SLI Question

    Hello, I've looked through several of the MSI Gaming motherboards, and I've noticed that they all support 3-way CrossFire, but only 2-way SLI. Why is this? Are there any MSI gaming motherboards that support 3-way SLI, or would I have to get a different kind?
    Thanks!

    Quote from: badboy2k on 10-June-15, 18:19:47
    the only z97 board that can do 3 or 4 way SLI that MSI makes is the Z97 XPOWER AC as it has PLX (PCI Lane Splitters) chips and can support PCI-E Gen3 (0, 16, 0, 0, 0), (16, 0, 0, 16, 0), 16, 0, 0, 8, 8), (8, 0, 8, 8, 8)
    Honestly, that's a hack and it should be avoided.
    The PLX chip comes with significant latency issues.
    Native CPU x8-x8 is faster than PLX x16-x16
    That's why the PLX chip is disabled in 2-way SLI on most of the motherboards who support it.
    It makes sense for 3-way and 4-way, but the performances boost is minimal.
    So the best solution is always a CPU with 28 or 40 PCI-E lanes.

  • P6N Diamond, SLI question: where does the 2nd card go?

    As per title, I have a P6N Diamond motherboard with 4 video card slots (four PCI-e x16), two yellow + two white. I have a single GPU/card in the first slot as usual, but I got a 2nd GPU/card today. Where does it go so I could get 16x16 SLI? Manual is unclear.
    2nd white slot (third PCI-e x16) or the yellow (second PCI-e x16) ?
    I ask because this motherboard has non-standard color coding. Even the RAM slots are not color coded (channel-wise). Instead of A-B-A-B color arrangement on the RAM slots as every other motherboard out there, this motherboard has A-A-B-B arrangement.

    Update: First of all, the case connectors on the motherboard are in the way for SLI purposes. They are too tall and block the insertion of the second card. On my old ASUS moterboard the case pins were on the bottom of the PCB, out of the way, but on this MSI motherboard they are on the side, lined up with the PCI-e x16 slot. Really dumb design! It might be fine for short video cards like 9600GT or similar, but for extended length dual slot video cards like GTX260 (which what I'm using) they are in the way, so much that the second card can't be inserted into the slot at all.
    I spent two hours modding the connectors. I had to snap and break the plastic plugs, remove the metal pins and mod them so they are only 3mm tall, instead of 9mm. I know this motherboard is old so MSI couldn't plan for GTX260/280 and other long cards, but cards like 7950GX2 and similar did exist and predate this motherboard so there is no excuse for MSI for placing the connectors in that position.
    Anyways, warning for any P6N Diamond owners: if you have extended length or longer dual slot video cards like GTX 260, GTX 280, and 4870x2 you will have problems with clearance and would need to do some severe modding or get a different motherboard.

  • NF980-G65 & Two 580's Sli Question

    My question is about x16 speeds if I install one 580 into the first pci-e x16 slot and the other 580 in the third pci-e x16 slot will both cards run at x16 speeds or will they need to be installed into slots 1/2? Thanks

    They need to be installed into slot 1 & 2:

    At least that is what I conclude from the spec sheet.  Try both configurations, if you want, and let us know the result of a 1 + 3 configuration.

  • P6N SLI Plat and g92 sli question

    Do any of you guys with this mb run it in sli with the new g92 nvidia cards and if so what kind of results did you get?  I'm very tempted to get another evga gts 512 and run it in sli however I'm concerned about the scaling in vista 64 and I'd like to hear from others who might have already done this.  I really haven't seen any benchmarks using this mb so I'm looking for some personal experiences to use as a guide.  I considered swapping mb's however if this one will yield good results I might try it first before spending more money.  Thanks.
    Edit:  I looked at the sale ad one minute too long and have already ordered it with overnight shipping.  I should get it tomorrow and once installed I'll let you guys know how it goes.  I'm sure that it won't be long before a new sli mb finds its way into my pc.

    Going sli with those gts will help when the going gets tough and deliver more frames per second for a smoother gaming expierence. Those new nvidia drivers havent made any difference as far as i can tell. I see youre using klipsch speakers good choice there is no better option in my mind for i own a set of chorus 2s for my stereo and a huge klipsch fan, nothing makes the neighbors hate you more than rattling knick knacks off thier shelves in the houses around me.

  • MSI P7N SLI Platinum sli question.

    Hi guys
               Since the pci lanes on this board work at 8x8 would that impair the performance of two 8800gtx or two 9800gtx in sli? Compared to a 780 sli board

  • Definitive answer on PP CS6 and SLI needed.

    Howdy gang...
    I'll be building a computer to run Premiere Pro and was curious about SLI capabilities. So, I did a Google search and found conflicting advice from this forum (and others) about the topic. As it seems I cannot contact Adobe directly, I'll try it here (although others have apparently tried to find the answer previously).
    I have GTX 570 that I removed from my gaming box after replacing it with a 670. From what I gather, the 570 is a nice card to use with PP. I thought I might add a second 570 if the improvement in performance was worthwhile. The best answer I've found on the SLI question was this one (thanks to the original author on a different forum): Premiere pro cs6 can use only one gpu for all the cuda stuff but the other gpu will not just be wasted.... it will be used for stuff such as display scaling , color space conversion etc
    He/she goes on to say the following:  After effects otoh will take advantage of both gpus....
    So, it appears to me that a second card would not be entirely wasted in PP CS6 and that it would definitely be to my advantage if I was to also use After Effects. Fair assumption?

    PrP uses one GPU for CUDA acceleration. After Effects can use multiple GPUs when doing Raytracing mode. Otherwise CPU is used .

  • Dual link? SLI multi-head?

    Hi all.
    A couple of quick technical questions. I own an IBM T221(9503)-DG5 monitor, which can be driven from a dual link DVI connector (plus a single link one).
    The NX6800GT-T2D256E is listed as having dual link support (in the chipset on the main page, and I believe there's a PDF which claims it too). However, I know there's been some confusion in the past - I understand that nVidia's reference 6800 boards really did have dual link (two SiI178s per output) connectors, but that these have been left out by all consumer manufacturers so far, and some other nVidia board manufacturers (e.g. Innovision) are still claiming dual-link support despite the fact that their cards provide two single link outputs. On the other hand, it's promising that none of MSI's other cards are listed as having dual link support.
    Can anyone confirm for me that this MSI board really *does* have dual-link support on at least one of its heads? Currently the only boards with this feature are workstation class (Quadros, FireGLs, Realizms, etc.) and the Apple DDL boards (the 30" cinema display also needs a dual link connector). Since I've no need for the other features of workstation boards, I don't really want to pay that kind of money for a part which is different only in some $30 interface chips... so I'll buy the MSI part like a shot if the support is there. MSI UK haven't yet been able to confirm with head office for me.
    Corollary: if there's an impending 6800Ultra version with the same connectors, I'll gladly wait for that instead!
    In a related topic, as noted above my monitor is best driven from two DVI outputs (one dual link, one single). However, I've heard a rumour that SLI is only supported on one head - I know it disables the output from one card, but this is more restrictive. In my case, both heads are driving the same display, so in theory the driver ought to be able to cope by treating both outputs as one frame buffer... but can anyone give me details on the behaviour I can expect? If I have to switch to driving from a single head, there's little benefit to me from trying to run an SLI system - at that would lean me even more towards a 6800Ultra, if one is in the pipeline.
    I'll need to buy a PCI-E system in which to put the MSI card, so I'm keen to be sure of myself before ordering even if I could return the MSI card should it not work as advertised.
    Thanks in advance for any information.

    Iiyama VMPro 454 (off the FX5200)
    Tagan 480W PSU
    That's probably about all that's relevant...
    Oh, and based in the UK.

    Since I found out the answer to my own question...
    The PCI-E 6800GT (OEM version of the NX6800GT-T2D256E) which I've got *really is* dual link - I can drive 3840x2400 at 25Hz from a single head, and there appear to be two SiI178s on board. Big hand to MSI. This presumably means that the board would be capable of driving Apple 30" cinema displays, although reports from people with Quadros suggest that the Apple display is a bit temperamental.
    Unfortunately, I've had trouble getting the single link head to run 1216x2400 at 48Hz, so I've not got the whole display running at 48Hz yet, but I'm told that may be an issue with newer drivers so I'll try again (or play with PowerStrip). There's always quad head mode if I give up on SLi...
    A word of warning: the second head on this card is DVI-D only - that is, it's a DVI-I connector, but with no analogue pins connected, so you can't use a DVI/SVGA adaptor to plug in an analogue monitor except on the primary head. That means that if you want a 30" Apple plus a CRT, budget for a second card...
    I'm waiting on a new motherboard before I can answer my SLi question, but I can live with the options I've got even if I don't quite manage everything I'd hoped for.

  • Question about CUDA and SLI

    So, I know that SLI makes no difference in Premiere, but my question is--does it have any detrimental effects? For instance, if I have two GTX580s SLIed on my system, will I still get the full CUDA benefit of one card in Premiere or will the SLI somehow reduce the effect?  Ideally, I'd like to have a system with both CUDA support and a 3 monitor setup.  AFAIK, with the Nvidia cards, the only way to get three monitors is to have two cards in SLI.

  • A Few Questions About The GTX 580 Twin Frozr/OC in SLI

    Hi everyone!
    I have a few questions if you guys don't mind answering them, first thing though to make it clear this system is not built yet but the build will start soon.
    My first question is whether or not this PSU is capable of running two GTX 580 Twin Frozr/OC in SLI:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817139015&Tpk=AX850
    +3.3V@25A, +5V@25A, +12V1@70A, [email protected], +5VSB@3A
    My second question is whether or not the GTX 580 Twin Frozr/OC will come with a SLI bridge connector long enough to accomplish a connection over this distance:
    If not where can I buy a bridge capable of accomplishing this?, the reason for this distance is to keep the bottom card from pushing air onto the top one.
    The above is a normal ATX form factor motherboard or to be more specific a ASRock P67 EXTREME6.
    http://www.newegg.com/Product/Product.aspx?Item=N82E16813157231

    Quote
    EDIT-
    I'm looking at the picture right now and it looks like the bridge that comes with the motherboard is not long enough, any suggestions on where to buy one?
    nope no idea, ask your reseller
    Quote
    I didn't mean the Watts I mean the Amps, from other threads in this board it seems that some PSU's aren't up to the task of supplying the card with enough Amps, I was wondering if that PSU could supply enough for both.
    Well you can figure from the graph
    With one VGA it drains total 447W, where single 580GTX need 40A-42A,
    adding second the same VGA to the system drains total 719W
    So 719-447=272W, 272W/12=23A, 42A+23A=65A
    or simple 719/12=60A

    BTW, I would also like to say I'm currently using a MSI board in my current build and I love it!

  • K9N2 SLI Platinum - JPW2 connection essential? Also, question about diagLEDs

    I've been running a K9N2 SLI Platinum with a Phenom 9950BE and 2 Geforce 9800GT video cards for half a year now, running as stable as any computer could and I couldn't be happier. However, there's one thing that I've always had a question about - the molex connection on the board labeled JPW2. The manual says that JPW2 is "used to provide power to stable the operation of graphics card", but using the PCI-E connectors on the card appears to be adqeuate to running a stable system.
    In regards to this though, am I running the risk of an underpowering my motherboard not having JPW2 plugged in? The 24-pin and 8-pin power connectors on the board are of course plugged in and my concern is merely (hopefully!) academic at this point, but I'm just curious if not having power running through JPW2 would cause any problems down the line. My components are power hogs and I believe my power supply is up to it, but I'd love it if someone wiser than I could indulge my curiousity.
    Also, my diagnostic LEDS are reading something other than four green solid lights in normal operation (successful POST, Windows loaded and running). If you were to view the motherboard correctly mounted in the case, the order of the lights are: [G][R][R][G]. The manual refers to this as "BIOS Sign On - This will start showing information about logo, processor brand name, etc..." which is as incredibly unhelpful as it can be when it comes to this sort of thing. I state again that this doesn't effect normal operation - it's just another thing that I'm curious about.
    Thank you for helping me put my mind to rest!
