Analysis of the modification technique in the Remarked CPUs
We clarified the technique of the modification in the Remarked Sempron.
Moreover, we received the report of similar CPU from the United Kingdom. The United Kingdom#1 The United Kingdom#2
We got a mail from Poland. Poland
The shipment from AMD of the SocketA Sempron has already stopped. We confirmed the Remarked Sempron 2800 existed in the market today.
Then, please look at the photograph of the genuine Sempron 2800 first.
This photograph is L11 bridge of genuine Sempron2800 +. The L11 sets the core voltage of CPU, and 1.60V is supplied to Sempron by this pattern. This time, please watch the L11 bridges. You will be able to find doubtful Sempron by this comparison.
Analysis of the modification technique in the Remarked Sempron 2800+
We obtained this high resolution photograph. And, it succeeded in the clarification of an illegal technique in the fake Sempron.
Modification to the close in the L11.
Please watch this photograph.
Modification to the open in the L11.
You will find the cut bridge wiring. In the photograph, it looks white. The recognition of the cut bridge changes from the close to open.
These L11 bridges are detected as 1.65V.
Modification of the multiplier in the L3.
In L3, an illegal modification by the dent was found.
These L3 bridges are detected as 12x.
Modification of the FSB in the L12.
In L12, an illegal modification by the dent and wound was found.
These L12 bridges are detected as 166MHz.
About these photographs
These photographs are Fake Sempron 2800 sold in Akihabara in Tokyo. We were going to exclude this from the market. Then, we sent the photograph of this Sempron and information on the shop to the Authorized distributor of AMD Japan. In addition, this information was sent to the call center in AMD Japan. We hear that AMD Japan contacted the AMD United States. As a result, only genuine Sempron was sold in Japan on June, 2006.

Remarked Sempron 2800+ from United Kingdom #1 [Septembar 04, 2006]
We received two reports of Sempron2800+ that caused the problem from the United Kingdom. Thank you.
thanks for a great site.
I sent a mail to AMD over a week ago along with the attached photo, but have not heard anything back from them. It seems that they are not bothered about remarked cpu's. I've since sent another mail and am waiting to see if they ignore that as well.
Here's my sempron, any ideas on whether it is fake or not.
As you can see I tried adding more heatsink paste after it failed in an attempt to keep the temperature down.
When contact is done to AMD directly, AMD seems to be passive about the Remarked Sempron. It seems to be more effective to do contact to the distributing agent of AMD. We will recommend speaking at that time, 'I want to offer AMD important information about the Remarked Sempron'.
It can be judged that the Sempron is abnormal if it is 1.65V. If it is defective CPU, it might be able to be returned to the shop.
Even if the investigation of the remark begins, AMD seems to be passive to opening the details to the public. Moreover, the system that neatly accepts the remark information seems not to function.
However, the power of AMD is necessary to exclude doubtful CPU from the market. We pulled one's coat to AMD. And, it succeeded two times in Japan in the exclusion of those CPU from the market. In addition, we heard that AMD had dealt with this problem at once in Germany.
It is 1.65V according to an illegal modification.

The report from another United Kingdom is Mr. Banerjee. We confirmed this Sempron2800+ was the Fake.

It's clear to me that the Sempron is fake, but the Duron looks so similar it also seems suspicious. Can you tell me whether the Duron is also a fake?
>Duron is also a fake?
It is 1.775V according to an illegal modification.
Though it doesn't understand who is doing . . . They work into the L11, and have changed the
core voltage into another value.

We received the report of the remarked Sempron2800+ from Poland. Thank you.

I went home, mounted processor, fited thermaltake silent boost cooling and turned pc on. Chandeg the FSB do 166MHz and... nothing wrong happend next, temperature was fine, about 40 degrees C. When I was stressing CPU maximum temp was about 51 degrees. my cpu works at 1.725V by the way. Next when I`ve compared performance with sisoft sandra with other processors my cpu was at the same performance as another similiar/same amd processors.
So, is it sure, that processors with pits at L8 and some other small changes are all remarked?
Please act carefully.
Of course, it is necessary to blot out the Remark from the market. However, SocketACPU is hardly supplied now. We have worry that the supply of SocketA might decrease further if this problem is exaggeratedly notified. It is the best for our user to solve it by what method.
Please note the following when you return the CPU to the shop.
Appendix L11 : VID Code for startup Core voltage
The following data is AMD GeodeNX1750.
You will notice this GeodeNX1750 is the same as the Remarked Sempron2800 +.
C is a closed bridge. The logic is 0.
Thank you for your report
We got the permission of opening mail to the public.
