AMD Processor Query

Hi,
The computer that i purchased almost a year ago has an AMD Sempron 2800+ processor. Can someone tell me whether this processor is 64bit or not. I know that it is definitely not a dual core but im not as sure about the 64bit.

I have used CPU-Z to get some info about my system and its reports that the processor instructions are x86-64! does that mean 64bit? The other info that CPU-Z gave to me about my processor are below.

Family: F
Ext. Family: F
Model: C
Ext Model: 1C
Stepping: 0
Revision: DH8-D0

Code Name Palermo

- Palermo (90 nm SOI)
- Early models (stepping D0) are downlabeled "Oakville" mobile Athlon64
- L1-Cache: 64 + 64 KiB (Data + Instructions)
- L2-Cache: 128/256 KiB, fullspeed
- MMX, 3DNow!, SSE, SSE2
- SSE3 support on E3 and E6 steppings
- AMD64 on E6 stepping
- Cool'n'Quiet (Sempron 3000+ and higher)
- Enhanced Virus Protection (NX bit)
- Integrated DDR memory controller
- Socket 754, 800 MHz HyperTransport
- VCore: 1.4 V
- First release: February 2005
- Clockrate: 1400 - 2000 MHz
- 128 KiB L2-Cache (Sempron 2600+, 3000+, 3300+)
- 256 KiB L2-Cache (Sempron 2500+, 2800+, 3100+, 3400+)
- Steppings: D0 (Part No.: *BA), E3 (Part No.: *BO), E6 (Part No.: *BX)

Don't know if this I usefull for you but I guess your CPU is able to run 64bit OS and such. Though you said your stepping is '0' (zero) which would be 'D0'. Which isn't E6 stepping so I can't say it with full confidence

Perhaps you could contact AMD themself about this? Or someone else has this CPU here on Astahost...

well... i don't think it can natively run 64 bit software...
i suggest everybody to check out the specifications from www.amd.com always check out the site of your hardware producer, they can tell you more than anyone..
good luck

Most likely it is since it matches the core's codename. I don't remember AMD producing 2 versions of their processors under the same codename.

This page has a list of all the AMD Sempron 2800+ models. http://www.amdcompare.com/us-en/desktop/Default.aspx Down at the bottom, it lists 5 different models. If you can match the model number (OPN PIB) to one of those five, you can check if it has 64bit support by clicking the view details link and looking for 32/64 under Operating Mode. If it has the /64 then it has 64bit support, otherwise it is only 32bit.

how do i find the Model Number (OPN PIB) for my processor. Would i be written on any documentation or would it actually by on the processor itself?

OPN is etched on the core or on the IHS.
same info about AMD cores @ wiki: http://en.wikipedia.org/wiki/List_of_AMD_S...microprocessors

Check out this website: http://www.ultimatehardware.net/166.htm and scroll down for the CPU-z screenshot. That's a 64bit CPU: look at the instructions list, at the end there's x86-64, that means it's a 64bit capable cpu.

Umm why would it support 64 bit instructions without supporting 64 bit, and if its the same code name... Like duh.?
