WTF! Is my 7750 actually a phenom?

[dingleberrydorkbutt]

Here's the numbers. I remember now that there was a discrepancy.

The sticker on the manual says:

AD775ZWCGHBOX

The processor says:

AD775J2BGHBOX

according to my notes.

I'll be testing it some more tonight. Hopefully the memory is OK, because I ned to hurry up and send in the UPC for a rebate. :disgust:

Are you sure about the processor number being AD775J2BGHBOX? A quick google search shows no match for that.

Since it is an ES that would stand to reason. Probably not a plethora of websites created to discuss one specific ES CPU.

 

[dbcooper1]

Would an engineering sample be labeled AD*BOX? I thought that indicated a retail packaged CPU with heatsink/fan.

Oh that's right. I forgot about that. The only thing I remembered about this thread at the moment was turning a Phenom dual core into a quad. Now it's all coming back to me.

I wouldn't think that they would label it as BOX...

This thread delivers!

 

[alkalinetaupehat]

Bookmark'd FTW. Anyone else thinking of the 6800GT days when you could unlock the extra pixel pipelines?

I was about to say the same. This is the most interesting thread I've read in the last, say, 6 months.

You mean the 6800 Nilla?

Just an update.

I flashed the newest BIOS to the board, and when I rebooted, it showed 4 cores and the "AMD Engineering Sample" in device manager and CPU-Z. Showed 4 cores over the course of 4 or 5 reboots, but when I went to over clock a little, it went back to 2 core status and hasn't shown 4 cores since. If I ever get it back to 4 cores, I'm not going to mess with ANY settings.

just reflash the board and see what happens.

try flashing it back to an older bios and then back to the new one...

And for the love of god take a screen shot of CPU-Z before you play with the settings.

 

[cusideabelincoln]

He's already taken a CPU-Z screen shot of it showing four cores and being an ES.

Too bad you can't have it switch dynamically, it would be sorta like Intel's Turbo mode heh.

More like the power-savings feature on i7 whereby it shuts cores down entirely when they aren't being used. Only need the processing power of a single-core? Well guess what, your i7 will only have a single core fully powered up and running at any given point in time. Etc. It is part of the reason the performance/watt is so darn good for them.

Well technically the Phenom II was supposed to have that feature... not sure about Agena parts though, don't think it ever made it into the drawing board for that. They scrapped it on the Phenom II though, can't remember why.

And yeah, the AD*BOX numbers are wrong. We would need the actual numbers off the CPU itself, not the box.

I didn't think it was scrapped with PHII, I though it just required a AM3 motherboard to use the advanced power features. I may be incorrect though.

 

[dbcooper1]

I think OP posted both:

The sticker on the manual says:

AD775ZWCGHBOX

The processor says:

AD775J2BGHBOX

Anand dedicated a whole page in his PhII review to discuss the technical merits and real-life suckage of CnQ for PhI vs. PhII:

Phenom II fixes this by not allowing individual cores to run at clock speeds independently of one another; if one core must run at 3.0GHz, then all four cores will run at 3.0GHz. In practice this is a much better option as you don't run into the situations where Phenom performance is about half what it should be thanks to your applications running on cores that are operating at half speed.

In the past you couldn't leave CnQ enabled on a Phenom system and watch an HD movie, but this is no longer true with Phenom II.

It would appear to be changed at the fundamental architecture level. Basically AMD needs Intel's PCU from Nehalem built into Phenom/PhenomII so as to mitigate the deleterious impact of thread migration...well, not Intel's of course as that is Intel IP, but AMD needs analog power control circuits of their own design to accomplish the same effect.

Side note: anyone else noticing the fact that Intel has really differentiated itself from the competition in both CPU's and SSD's by not just producing better hardware but by making the hardware be more intelligent about the fact it is operating in a non-ideal environment? (namely MS Windows, thread migration kills power savings on CPU's and random writes kills performance of SSD's) Smart cookies there.

Well, with an R&D budget the size of what Intel has, I would hope they put that money to good use. What surprises me is that Microsoft probably has a LARGER R&D budget, but they seem to be handcuffed into making smart hardware run like crap (sometimes).

Yes, and to whose benefit? Careful now, we'll have our tin-foil hat participants formulating more conspiracies...

 

[Insomniator]

Well anyway what the hell are the chances of probably the only ES sample sent out by newegg actually going to someone that posts on these boards?

They must have sold thousands of those cheap dual core chips, and I've never heard of an ES ever being sent out by accident any other time.

If the probability is not zero then it is only a matter of time before it occurs.

It sounds like the OP got a rebadged ES. The chip lived for some time as an ES, then was rebadged as a Kuma and shipped to market. Nothing illegal about that.

It may surprise some of us to find out that ES's get rebadged, but if you are a company that has been bleeding cash for 2+ yrs and you need to ship for revenue every sliver of silicon you can lay your hands on then you certainly aren't going to let fully functional ES chips sit on a shelf when you could still sell them.

 

[zerogear]

Did it show 4 core at standard clock? I think I might try setting it to 2.9 on a Kuma I built a week ago.
