G580 CPU Upgrade problem

[camelweb]

Hi all!

I have an older G580 laptop. It came with a B950 CPU and i wanted to upgrade the CPU.

I studied the Hardware Maintenance manual for the supported CPU's.

On page 101 it says (amongst others):

Intel SNB I3-2350M 2.3G 3M J1 PGA Processor.

I found one like that cheap and i bought it.

I installed it succesfully, but it does not work correctly.

Although it has 4 threads, any software or test only detects 2 cores, 2 threads. It seems that hyperthreading does not work.

Laptop model is G580  model name 20157

BIOS is the latest i could found, version 62CN97WW

Others reported the same problem and solved it by BIOS update, but i cannot find any newer BIOS than this one.

Please help me.

Your new CPU is 2 cores, 2 threads each for a total of 4 threads.

Your new CPU supports hyper-threading.  Check your BIOS( at current version) to enable this feature.

Hi!
Thank you for your reply.
Unfortunately in the current BIOS the only related setting is is this one:
"Intel Virtual Technology - Enabled"
If you have any ideas what to check in BIOS, please share.
