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?

Maybe because Geekbench is in 32Bit mode?

Have you tried any other benchmarks like 3dmark, or cinebench?

oh, and i also noticed that geekbench said it was a Zambezei, and the 8350 is a Vishera?

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.

Your motherboard does not support AM3+ cpu... That's probably the reason... it's an AM3 motherboard

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)

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.

I looked on the supported CPU list and it shows 8350 supported at BIOS F3.

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.

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.

Newegg site says:

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

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.

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

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?
