Dual Opteron's

Hi.
Will I get better performance with Dual CPU's instead of a Single CPU?

Depends what software you are running.
Most programs can only use a single CPU. They are described as "single threaded". Some high-end apps are multi-threaded, which means they are written to use multiple CPUs by running as small indepenant "threads". One thread uses one CPU while anothe uses a second.
So if you run Photoshop, 3Dstudio Max, Cinema4D, Adobe AfterEffects or other things like that written as multi-threading programs for multiple CPU systems then a dual Opteron will run nearly twice as fast as a similarly clocked single.
Equally, if you run multiple progams that can use as much CPU as they can get simultaneously, than 2 CPUS will help.
But most people don't do that. Few programs even use 1 CPU to the full. With 2 CPUs you could set a program to rendering video and then play games while it was running, but it's rare on a home PC to have multiple programs that need the CPU running at the same time.
In which case the second CPU will give you at most a few % improvement.

  • A single Amd Fx 51 or Dual Opteron 248's????????????

    I have asked you many questions over the past few years and I have another question for you.  I have the option to run dual opteron 248's instead of my Amd fx 51.  Would I see a performance gain?Or would it be a waste?

    FX-51 = 2.2 GHz
    Opteron 248 = 2.2 Ghz
    So clock-for-clock, both CPU's will perform roughly the same, and both have 1Mb cache.
    So for things like gaming, there won't be much difference, HOWEVER if you are using multi-threaded applications (eg. encoding, rendering), then you DEFINITELY want to go the Dual Opteron route.
    My 2 cents!

  • WARNING... K8T Master 2 FAR Dual Opteron upgrade

    Anyone owning this board who has set up with one processor with a view to upgrading to dual beware.
    I recently assembled a machine in MAY 2004 using one AMD 242 Opteron, the system works fine and as Opteron prices have dropped i ordered the second one. Despite the short period of time between the two orders the processors are incompatible. I include an extract from an e-mail from AMD tech support
    Based on the part numbers that you provided me for your Opteron 242
    processors please note that based on their revisions they are not
    compatible so will not work together.
    OSA242CC05  AH --> AH part # is a B3 revision
    OSA242CEP5  AU --> AU part # is a CG revision
    Please ensure that when putting these processors on a dual processor
    motherboard both processors revision #s are the same.  I have included
    a link for you below with information on how to determine the revision
    # for your processor.
    http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/30417.pdf
    I am assuming that it would be fairly difficult to track down a match for the first processor so i will probabltyhave to order a third processor to match the new one which leaves one spare...for what?
    I hope that this information will help to avoid you wasting money and valuable time trying to set up a basic dual opteron system.

    Have you tried looking at the serial numbers through the packaging on the retail boxed version, it is difficult enough to read with the processor out of the packaging and there is nothing on the outside of the packaging to diferentiate one batch from another. Pretty pathetic considering AMD designed the 242 series for dual boards.
    no i havent but i know its possible to get athlon xp with a certain number in sweden.
    and if its like this it will give amd bad reputation.

  • [Opteron] Dual Opteron nForce 3 250 Ultra board?

    Hi
    Does anyone know when we can expect a dual opteron nForce3 250 Ultra board from MSI?
    Looks like iWill is the first one out of the gate with such a board.
    Thanks in advance.

    Hi Paul,
    I think that there will be no problems - if you include a good PSU in the set up.
    I would recommend to see what BIOS there is coming with the board - 1.9 or higher will recognise the X2 CPUs. If not strictly necessary, I would advice against flashing the BIOS of this board, unless - of course - you encounter specific problems. In that case I would flash an official BIOS (1.B) and not a beta, or modded BIOS.
    At present the 4800 X2 is still quite expensive; the 4400 X2 is much better from a price/performance point-of-view ...
    As far as RAM is concerned: why would you want to run 4GB of RAM? For normal programs/games, 1GB is more than sufficient and only with some of the newest games a noticeable increase in performance can be seen when 2GB is used in stead of 1GB. It is hard to imagine that adding 2 GB more will lead to an increase in performance. Instead it must be expected that you will loose performance (because of dropping to 333MHz, looser timings, etc.). I therefore recommend to go for 2GB of good quality RAM.
    Hope this helps,
    Hans

  • Dual opteron supported on arch ?

    I am thinking about a system with these parts :
    supermicro H8DAE-2 motherboard
    dual opteron 2379 HE processor
    8 Gb for each processoor = total 16 Gb memory.
    Is such a setup supported with 64-bit Archlinux ?

    Dual Opteron processors are supported by the Linux kernel, so I guess it is supported by Archlinux too; also the 16 GB memory is not a problem

    I am new to this forum but had been working on this problems for a week!
    Here my system:
    MSI K8t Master 2 FAR

    Dual Opteron 250 replaced the dual Opteron 242 one week ago
    BIOS upgrade to 1.4

    The POST, Device Manager detect two new CPUs. However, there are only one CPU being utilize in task manager (yes, I have check one graph per CPU). It appear from the forum that BIOS 1.35B5? would work but I could not find it. Try to install Window XP Pro but failed (flopppy drive does not work).

    With BIOS 1.1 and dual Opteron 242, I have both CPU work as shown by Device manager and task manager (two CPU graphs). I can only get one CPU work since I upgrade to Opteron 250 and BIOS 1.4. Unfortunately BIOS 1.1 do not support Opteron 250.

  • Trying to assemble dual opteron system, no display.

    My system:

    I finally got all the parts and tried building my first self built pc with a friend. I have everything plugged in, all the fans spin, controllers light up, heatsink fans spinning. and im pretty sure the hds are going to, but nothing shows up on the monitor. I even put my old geforce 2 card so i could make sure it wasnt the 6800, but even that wouldnt work. My board has no onboard video so i cant use that. What do I do?

    Well I got my new psu, put it in and tried everything. One processor, one stick of ram (only ecc ram I have), two sticks, 2 cpus and one stick, ect, reset the jumpers. But someone said the board needs a bios update to run the 250's. So I was pissed I may have to buy a 140 just to update the bios. But I called MSI and they are sending me a new bios chip with the latest bios on them.
    Think it will work?

  • CAN'T get new dual Opteron to POST!

    I just boaght a new MB/Chip/RAM set, consisting of:
    2 x Opteron 244
    MSI K8T Master2 - 9130 motherboard
    2 x Kingston 1GB Kit 400MHz DDR Registered ECC Double-Row 3-3-3 - KVR400X72RC3AK2/1GD
    I'm using a 500 Watt PSU and an ATi 9700 video card. I have not been able to get it to post in this vanilla state. I have checked to ensure no shorts between the MB and case, have checked for bent pins on all IDE ports, chips, and jumpers, and have tested the system in all configurations from just chips, to a full system. No post at all. Any ideas? Need any more info? I'm desperate at this point, since I am all the tech support I have in my neck of the woods.

    Yes, of course I did connect the main power.  I get power to all the fans in the system, but no post.  I never use the AGP pro power on my PSU, since none of the main stream cards ever decided to use it.  I got the board from newegg and have noticed that the only major issue them seem to have is sending out bad components.  Friends, reviews, whatever, they all seem to say the same thing.  I'll probably end up RMAing this thing.
    As for my PSU, it's a Powamax 500w.  
    +3.3@28A,+5@30A, +12@25A, [email protected], [email protected]
    It ran my dual MP system fine, and should have enough juice to post, even if it's not a top quality PSU.  I've never seen a PSU with this much wattage with less than 18A on the 12v rail, so it should boot up considering I have nothing else plugged in.  In any case, I did order one of the MSI recommended PSUs, and Enermax 460w.  If that does not work, back it goes I guess.

  • Driving MSI Dual Opteron Master2

    So, there I was at the swap meet standing in front of this dual socket mainboard with a red printed circuit board. It was beautiful! And, I think it was calling to me faintly. It apeared to have never been removed from the wrapper and it was resting on a retail box. A Lady walked over to me and said, "I'll sell it cheap if you buy it now...?" It was late in the day and people were leaving. "Where's the rest of it?" I asked. There was nothing included but the board. Basically a heap of scrap without the CD, I thought.
      As it turned out I walked away with it tucked under my arm after handing over a few coins. Arriving home I shot on the web to MSI. I typed in MS9130 at every search bar on every page for ten minutes. No Data Available! was returned every time. Then I tried K8TMaster2FAR. Nothing. Ah Hah, I thought. No wonder it's so cheap. I Bought a board that MSI doesn't even support. Well, judging by the specifications listed on the box, I knew it was too good to be true. I could not even make up a more impressive listing except perhaps the Asus with PCIe.
      So, I guess the question is...is there a way to get a CD from MSI without the standard sacrificial first born child, please? They have never answered any of a dozen E-Mails.

    Didn't help :-(
    I am runing out of ideas :-(
    - Tested RAM over the weekend 68 hours and no error detected.
    - Changed Video card, HDD, CD-Rom
    - Tried every posible combination of BIOS parametars
    - Puting in and out processors
    - Changing memory voltage
    - Power on in and out of the case
    - Tried to contact (SUSE, MSI, Transcend) - some luck here ;-)
    System still unbootable.
    And now some good news.
    Guy from Transcend answered me promptly. They will try to recreate my problem and give me some feedback.
    Found and installed MSI K8D Master-F MB, and i have system intalles and boot (SUSE in fail safe mode). I will figure it out how to make it work correctly i hope.
    I would like if i could finaly get some respond from MSI. Or anyone who tryed 8GB combination.
    I let you know if something new come up.
    Thank You for Your replays.

  • Opteron VS A64 Performance

    I am totally happy with my Athlon 64 3000+ but as a hard core enthusiast, I have been thinking of moving to a dual opteron setup. comparable clock speed opterons are extremely high but I am sure a slower running opteron can provide the same performance of an Athlon 64 and more in a dual cpu setup. Which would be a cost effective dual opteron cpu with the same performance ratio?

    Jorge
    Duallies are great for multitasking, there's no debate about that. But like i said, if the dual CPU system has the "same" clock speed as the single CPU system then it will run faster. But if the dual CPU rig has slower CPUs it will run slower in games but smoother  in general. If dual CPU rigs were faster in games don't you think Alienware would be selling them for gaming instead of workstation applications? Getting a duallie rig seriously limits your upgrade options too. The extra cost is just not justified imho.
    Just my 2 cents.

  • 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.
    Andrew Garrard
    Prospective system:
    Tyan 2895 (dual Opteron SLI)

    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.

    Yeah, not matter what the HDD order is winxp always tries to boot from the single drive when its plugged in.
    Not sure if this only happens to me or if other people have had similar issues.
    IDE drivers becomes automatically as 1st HDD. you need to switch them.
    have you arranged hard disk boot priority? (not main priority)
    have a try to push "F8" or "F11" during post to popup menu, and choice correct HDD to boot from there.

  • K8T-Dual + 242s not booting (Ram??)

    Here's the setup:
    MSI K8T Dual
    Opteron 242s
    Antec 300w also tried Austin 350w
    266mhZ ECC Registered (512x4) also tried DDR333 VData low density 1g sticks (x2)

    Here's the problem:
    When I turn the computer on, it gives off a steady beeping noise (beep, 1 second
    pause, beep, 1 second pause, beep, ......).  No video, no other activity.
    When I unplug the ATX J1 power supplement, it does not beep, but it also does
    not boot.
    Does this sound like the ram-not-good-enough syndrome?  
    If so, what is an inexpensive reliable solution (we need 2 gigs of RAM).
    thanks much,
    Rob

    Was the 12v 4pin cable plugged into the 4pin plug near the AGP slot? It should not go there as that is for AGP only and is an Output for an AGP Pro video card(I wish MSI had used a different connector, But they didn't), I'd plug It into the the 8pin port(On the end nearest to Your psu) and pray that You didn't kill Your motherboard in the process. Oh and the 20pin psu cable goes into the 24pin port on the right end of It and the 4 leftmost pins should be empty, Unless You have an adapter or an SSI type PSU.
