GA-990FXA-UD3 and AMD FX-6100

[iaintkd]

Thought please,

building a new machine so went for the GA-990FXA-UD3, AMD FX-6100 bulldozer black edition, 8 gig Kingston hyper X DDR3, HD 6870 Graphics and a 750w PSU. Put it all together and nothing, fans spinning but no post, then I found out about the bios upgrade, so picked up an AMD 64 x2 250 chip to get me going with plans to ebay it later or build a linux box with it.

Anyway flashed the bios to F6f and thought great here we go, stuck the bulldozer chip back in nothing, fans all spinning but no post. Stuck the Ahtlon 64 x2 250 back in, everything fine, windows 7 installed, steam installed games downloading everything going great.

So thinking it's a duff CPU or is there something I need to set in the bios before it will work?

Nope, i started with a FX6100, no problems, ran fine on the same motherboard.   I have an 8150 now, still runs fine oc'd.   The only thing i can think of is the memory, what type of DDR are you using?

You can run memtest search google for it it is free but as your ram works with other processor and I am sure you reset bios to default id guess processor.

I'm running 2 x 4gig Kingston HyperX in dual channel in slots 1 + 2

KHX1600C9D3X2K2/8GX

Motherboard setting are all Auto just now for memory and cpu the only thing I've configured is raid 0 for the hard drives. The machine has been running for over 24 hours now constant download from the steam sale and browsing the web, not a single issue so far.

Think I'll RMA the cpu but wanted to check I wasn't missing something with the board for the AM3+ support as it's a while since I've used Gigabyte and AMD.

[iaintkd]

ok, arranged a RMA but thought I'll give it one last try just before I send it back.

So turned the machine off, took out the battery and removed the Athlon CPU, put the Bulldozer back in and I noticed it just didn't seem to be sitting correctly, gave it a little wiggles and click sitting nice and flush.

Post and boot into windows 

Powered down and took it out cleaned up all the old heat sink paste and applied some new stuff, checked the Athlon again, drops in nice and snug, the bulldozer again had to give it a little wiggle and click in it goes.

Everything running nicely, so one happy user. Never had a chip that didn't just drop into place before, it just seemed to sit just a little off flush until the wiggle and click.

Glad you got it figured out in 12 years only had one duff processor. Also thank you for posting what you did to fix it so it might help others.

quick question, How do you know if you are running 6 core CPU? I have the same motherboard and cpu and CPUID shows that I have 3 cores and not 6. If you go to task Manager>Performance>Resource monitor, my windows 7 shows CPU 0, CPU 1 and CPU2. Isthere any other way to find out how many cores I have? Pls help.

Thanks

Welcome to Gigabyte forum.

One of my favorite programs for an in depth understanding of the entire system is SIW [System Information for Windows].  They have a free version that I use on every system I have built and it works incredibly well.

Here is their website:

http://www.gtopala.com/

Be sure to download the free version so you need not pay for it.

This software will show you nearly every last detail in your system including the temperatures of every core, Northbridge, Southbridge, etc.  It is incredibly comprehensive.

Hope this helps!

Of course you could always press CTRL+ALT+DEL and bring up the Task Manager and on the performance tab it will show all cores running.

Here is my information about my CPU using SIW:
Number of Physical Processors     1
Number of Cor per Processor       3
Number of Logical Processors       3
so... I'm running with 3 Cores instead of 6. What else I need to do to fix it?

Be careful before assuming there is a fault with the CPU or that it is not running all 6 cores. The FX processor is new technology and sometimes it takes a while for software developers to catch up.

The best way of checking how many cores your processor has is to do one of two things. As Dark Mantis has already stated, start Task Manager and then click on the Performance Tab. This will show a graphical indication of how many cores the Operating System is seeing and using.

The other way is to go to Control Panel/Hardware and Sound and click on Device Manager. This brings up a box that shows your system's hardware components. Find the heading for Processors and double click. This will show how many cores (or processors) are being identified.

I had to contact Gigabyte and they suggested to install Bios F5, and that's it win 7 says I have 6 cores. Thanks.
