    Traces of storage in the basement. Was ordered on November 17, but arrived on December 2, that record for my city, while all the way tracked, I.E. Delivery deserves praise. Packing in a puffy envelope, then a puffy wrapper, then a thin porous winding, after an elastic band, and already the stones themselves lie each in their plastic transport box. Took for a good friend, whom I hope to revive the home PC hope to add jumps in addition to the SSD. Just in case I took about too “q9400”, although most likely I will give my son for his favorite gaming PC. Bonus paste, as last time, not included. The check will pass later, I hope the stone is serviceable, and the modified BIOS supports it, although, the standard also needs to perceive it, it’s a full-fledged processor.

    Customer

  72. A***v

    The processor went to me for 17 days. Packed was excellent. Plastic case, extensively rewrapped with packaging material and film, tortured to unwrap all this case :). The processor itself shows that he saw life. On the lid there are scratches and other shortcomings, it’s not scary. But from the contact side everything looks great and like from the factory. Started it on the board ASRock G31m-vs2, immediately felt the difference with Core 2 Duo e7500. Temperature with gammax 200 t in a simple about 40 degrees, which in principle is not bad. I tried to run on a boxing old standard cooler, then there is already all sad, although the size does not say that it is small. The temperature ranged from 50 to 75 degrees in a simple, so think about cooling if you are going to upgrade some old PC with this processor.

    All Hello ordered this processor, problems with delivery did not come quickly. It is clear that the used processor is working but I did not check and got it, it turned out that my motherboard supports quad q8400 but with an index s that is Q 8400 s. And this means that my motherboard supports this percent but with less TDP 65W and this 95 W. There are no pritenzy in the prodovtsu.
