AMD FX-8350 Eight Core benchmarks very low?

Hello,
I have an AMD FX-8350 Eight core processor that i just put in my pc and went to becnhmark test it and the charts say it should be a little over 11000, mine benchmarks at only 7000, and on the results page of Geekbench 2 it says my processor is only 3 core? I went into to the BIOS and changed cpu core control to manual and they all say enabled? any ideas?

    oh an btw heres my setup:

    GIGABYTE GA-78LMT-USB3 motherboard
    8GB Corsair Vengeance RAM
    500GB Seagate HDD
    1TB Western Digital HDD
    Dynex 400w power supply

    i also have (in case its relevant to power consumption or something, idk)
    2 dvd drives
    ASUS network card
    Rosewill 40 in 1 card reader
    2x enermax silent fans
  2. Maybe because Geekbench is in 32Bit mode?

    Have you tried any other benchmarks like 3dmark, or cinebench?
  3. ya i treied passmark with same results
  4. i just tried cinebench and it says it has 4 cores and scored a 3.41
  5. bump

    anybody? :/

    if you need me info from me let me know i just want to get this figured out! hopefully i didnt get a junk cpu!

    oh, and i also noticed that geekbench said it was a Zambezei, and the 8350 is a Vishera?
  6. So, does windows show it as having eight cores/threads if you go into task manager? If not you probably have a problem in the bios. Have you updated your bios to the latest version?
    I was looking at the specs for that motherboard and it doesn't show support for the FX 8350 only for the 81xx series, so that might be a problem.
  7. no, task manager only says 3 cores as well
  8. Update your Bios and see if you can find the windows optimizations for bulldozer.

    Your motherboard does not support AM3+ cpu... That's probably the reason... it's an AM3 motherboard
    http://www.asrock.com/news/events/2011am3+/
  10. no, it DOES support AM3+, it says it on the box, and on gigabytes website, and ok i just need to update my bios, gigabytes website had a specifice note that said to get the fx series CPUs to work u have to update bios, well how the heck to i do that?? i downloaded the "bios update file" it extracts into a batch file, an EXE and a .F4 file, and the exe and batch file both say the exe had problems with 64 bit but it doesnt give me the option for 32/64 anywhere??

    I'm not sure if the chip will ever work right on your motherboard but a bios update might help....:

    Search the webs how to update the bios on a gigabyte board. : In general you need to have a usb-drive format it, plug the usb-drive to your computer go into the bios and use, "what ever the gigabyte bios update tool is called", inside the bios

    WARNING:
    If a bios update is interrupted (powering down the pc in any way) you might corrupt your bios making it unusable luckiely you board have two bios chips so in case of a failure it will fix itself... (as far as I know)
  12. If your motherboard has dual-BIOS, you should verify that the back-up BIOS is the same as the main BIOS.

    Check your manual in the BIOS section for specific instructions.

    One way to update bios for a Gigabyte motherboard is to use a USB drive that is formatted with FAT32. Copy the .F4 file onto that. Boot the computer with the USB drive in, choose Instant flash or something like that from the bios menu, select your usb drive, then select the bios file. This should update your bios.

    However, as I mentioned before the motherboard specs says it supports AM3+, but only the 81xx series not the 83xx series, so it is possible that you can't use that cpu with your motherboard.

    You are really reaching here, I think. If the CPU is on the supported list, I don't think they meant "well it works, but only with 3 cores!" I would also suspect it's just a BIOS update.

    Of course it could be a chip with a bad module or two. That happens too.
  16. i cant get the supported cpu list to load up right, but on newegg when i filter mobos by fx supported it shows up as well?
  17. I looked on the supported CPU list and it shows 8350 supported at BIOS F3.

    http://www.gigabyte.us/support-downloads/cpu-support-popup.aspx?pid=4305



    Download and install the @BIOS utility and it will let you run the update. Also make sure that all cores are enabled in the BIOS and that it detecting it as an 8350.

  19. i used the @bios to update it and still no fix but device manager shows it correctly as an 8350 and it shows it 8 times so it appears correct
  20. So what's not fixed?
  21. it still benchmarks low, and when i go to task manager it says its only 3 cores still
  22. so i want to hear your solution to that 3 core problem!am all ears!
  23. uhh..?? i dont have a solution to it, thats why im here asking for a solution to it...??
  24. sorry for the confuse but it was actually a question for wisecracker!
  25. oh and i tried flashing from a USB drive, i formatted the drive, put the .f4 file on it, hit the button to go to "Q-Flash" and went to install from drive and it says no drive was found? tried multiple usb ports
  26. what does CPU-Z say?

    Do you have all cores enabled in BIOS?
  27. and yes al cores are enabled in bios
  28. well the cpu-z revealed the truth heheeh! :D
  29. What does the mainboard tab show in CPUz
  30. i had it updated to F4 and it still didnt work so i tried F3, thats why its on F3 now instead of F4
  31. I really don't know what the problem is but I notice your mainboard CPUz tab says:
    Chipset 780G
    Southbridge SB700
    Gigabytes spec for your board says:
    North Bridge: AMD 760G
    South Bridge: AMD SB710
    And looking at gigabyte boards that have the 780G & SB700 they are AM2+ boards that support AM3 but not AM3+. Note I found this by typing "780G + SB700" in the search box on gigabytes site. I also notice the only board that matches your model no GA78LMT-USB3 says its a Rev. 4.1 so I am guessing you have an older version of the board. Does your board have any DDR2 RAM slots? If you bought it from somewhere that advertised it as AM3+ I suggest you return it.
  32. its truly a mysterious problem!have you tried unplugging the cpu and plug it again?
    only thing i can think!
  33. i bought it from newegg and no it doesnt have any ddr2
  34. and ya ive had the cpu in and out a few times
  35. Newegg site says:
    North Bridge
    AMD 760G
    South Bridge
    AMD SB710
    Which is not what you have received, so I suggest you ask them what they think. Does your bios confirm the 780G & SB700?

    You have yet to directly answer my question.

    Is your backup BIOS the same as your Main BIOS?

    If you have a Backup BIOS --- READ your manual.

    Edit:




    If the BIOSs are not the same, they corrupt each other
  37. sorry, i dont beleive i do have a dual bios? how can i tell?
  38. Read your manual

    The GIGABYTE GA-78LMT-USB3 motherboard has a dual-BIOS

    If not, you have spec'ed us the wrong motherboard
  39. Wisecracker said:

    This is not necessarily true. I have a Gigabyte motherboard with dual bios, but the backup bios is an old version, that is never used unless something happens to the bios being used.
  40. oh ok then how do i know which one i am flashing or weather they are the same or not?
  41. looks like something has gone wrong. either you installed the wrong bios or you have got the wrong motherboard. because the board you have should have the 760g chipset and 710 southbridge.
    yours is showing the 780 chipset and 700 southbridge.

    recheck your make and model on the site and make sure it looks identical to the picture shown.

    your motherboard should be pretty much all blue if its got yellow and red memory slots then its not the motherboard that is on the box and some 1 has made a mistake.

    you should also manually download your bios not rely on the gigabyte software to download it automatically. i nearly downloaded the wrong bios with it myself for my x58-ud5
  42. it is all blue pretty much, i first tired etting @bios download and install the bios, then when that didnt work i went and manyally downloaded them, ive done that like 3x time so i know ive been picking the right mobo
  43. not sure if it was related or not but last night it started acting REALLY sluggish then after a while i restarte it and it wouldnt lad windows, it owuld boot into windows, but as soon as i would type in my password and hit enter it would hang there. i could get it to boot and log into windows 7 just fine. i ended up "refreshing' windows 8 and i can now get back into windows, performance seems quite a bit better (than the very slow speed last night) and when i go to task manager now it says "cores: 4 logical processors: 8" so that is what i want to see right? or should it say cores 8 also?
  44. I think it should say 8 cores what does CPUz say now?
  45. Cpu-z does say 8 now
