Identify this CPU

[bmartin]

Ok guys, this one is for the [H]'ers who rock.

I recently bought a 3.06ht p4 with 512 cache. Little to my knowledge, there are 2 different models, the 3.0e and the 3.0c. How the hell do i tell which one I have? I have tried sisoft sandra, nothing, and the intel cpu identification utility. I need some [H]elp!

Which one is better too?

3.06GHz only came in the Northwood variety with 533MHz FSB. 3.00GHz comes in both C & E, Northwood with 800MHz FSB & Prescott with 800MHz FSB. The difference there is 512k L2 Cache versus 1MB L2 Cache.

 

[napster0317]

The 3.06 that you have has 512K cache right?

well deducting that all the other northwoods have 512k L2 cache
and the prescotts have 1+ mb L2 cache i would have to say that it is a northwood, 3.0C

I had a prescott, and now have northwood, i understand the difference a little.

No. It's a Northwood B.

3.06 was a chip on the 533 bus. Northwood B.

 

[theNoid]

i believe e = prescott, c = northwood ??

It is a Northwood core, 512M cache. Is the 3.0c better for overclocking?

If you have a 3.06, it's a Northwood B. I've heard those tend to be pretty bad OCers because they already use an incredibly high multiplier (23 x 133 Mhz FSB).

The 3.0C Northwood has an 800 Mhz FSB (effective), and it's a decent OCer.

But yes, with 3.06 Ghz, you have the Northy B, or 3.06B.

The C and E do not have the .06 trailing after the Ghz rating.

hmm...

well, the multiplier in both identifiers I used both said 800fsb by 15x200, so maybe i do have a C core. On the other hand, it is the Northwood core, so I dont know. Thank you everyone for your [H]elp.

 

[BillLeeLee]

Well, if you have 15 x 200, then it's the 3.0C Northwood.

Try using AIDA32 and see if it tells you.

Nyce. Thanks all. I am @ work, so I will try it as soon as I get home. Thanks for all your help.
