What is CG Revision of the A64

I keep hear people talk about getting the CG version of the A64's. Since I am fixing to build an A64 3000+ system, any help would be appreciated.

Thanks!
 
it's a later revision of the Athlon64 core that changed some of the power handling and tightened up some memory timing stuff (i believe...i'm only operating on half my cylinders this morning, so i could be giving you a bad answer). btw, there's a nice 3200+ in the FS room... *obvious plug*

cheers,

dave
 
Is there anyway to tell? For example, I am looking at the OEM 3000+ at newegg right now.

Dave: If you drop your price any, PM me.... I could easily be talked into it ;-)
 
I believe the question is; How can you tell which revision the chip is before purchasing the chip? I'm looking at the A64's as well, and I can't find any mention either on the AMD site or newegg as to which version of the chip you would be buying.

Since I'm leaning toward the 3200 Clawhammer, I'm hoping that since newegg is currently out of stock that whenever the get a new shipment in, it will be the new revision. But if anyone can tell me how to tell beforehand whether it's CG or CO, I'd appreciate it.
 
NewEgg has both the Clawhammer and Newcastle versions of the 3200+. All the Newcastles are CG steppings. The older Clawhammers are CO, the newer ones are CG. I can't find any info on NewEgg that would let you know which Clawhammers they have in stock and are selling, although as time goes buy I would think the stock of the older CO's would be depleted (they may already be).

If you can get the part no. off the chip, that would tell you. The last 2 digits of the number reveal the stepping:

Example: ADA 3200 A E P 5 AP

AP = CO
AR = CG
AX = CG
AW = CG
 
Darn CPU-Z tells me mine is a C0. I just bought it from newegg.com not too long ago. So what are the major differences again? Doesn't seem like anything noticeable but it's kind of annoying if it is.
 
I don't know how much weght to give to what CPU-Z tells you. When I run it it says my 3000+ 64 cpu is a Newcastle, and it's not, it's a Clawhammer (I bought it before the Newcastles even came out. ) (And CrystalCPUID correctly identifies it as a Clawhammer.)
 
A 3000+ clawhammer is clocked at 2.0 and has 512K L2 Cache. I don't know about the 3000+ Newcastle...it's probably the same since clocking it higher would make it the 3200+ Newcastle.

I thought the move down to 512K cache was the newcastle. No?

Well that is true but only for the 3200+ and 3400+ Clawhammers. The 3000+ Clawhammer only had 512K L2 to begin with, same with the 2800+ Clawhammer.
 
Like what the man said. I have an ADA3000AEP4AP. It's a Clawhammer 3000+, early one. It's got 512k cache. They just disabled half of the onboard cache. I'm pretty sure the only 3000+'s you can get now are Newcastles (like the one at NewEgg). Both 3000+'s are clocked at 2.0 ghz.
 
hehe, I seriously doubt it or we would all know how by now...and I definitely wouldn't have bought the 3200+ clawhammer 🙂.
