Latest X2 939's

[tbz_ck]

I have a 3800+ that I bought last week.

Its currently sitting at 2600Mhz at 1.425V.......and I believe it isn't anywhere near its limits! Other people have had 2.8 to 2.9Ghz out of them which for a £40 chip is superb.

So are these chips all based on a much higher spec (i.e last FX chip) and just downclocked for different price segments? They all seem to overclock stonkingly well!

All of the chips come from the same process for making x2's they are just speed binned depending upon what the chip testing says that they can do reliably and what the market is asking for. Then if there is a large demand for 3800's rather then 4200's then more chips are tasked to the 3800 clock to fulfill demand.

It costs as much to produce the entry level model as the top model does, as such you can get an x 3800 that performs well enough to be sold as a 4800 or even better but market demand bins as a 3800, conversley you may get a 3800 that can only do the 3800 speed and won't clock at all. It isn't faulty as it does what it says on the tin and runs as a 3800.

I think that the average maximum stable clockspeed of the S939 X2s still available is quite high because they're from a mature manufacturing process. They have to be amongst the last made. Stable clockspeeds tend to increase as the manufacturing process is refined.

In other words, I think most of them are as described by mdjmcnally in their first paragraph.

I also think that they are stock that needs to be sold. Better to mark them at a range of speeds and sell them for some profit that mark them all at higher speeds and have some unsold as people decide to put the money towards a more complete upgrade (which nowadays would probably be a Core 2 system, particularly bad news for AMD).

Mine runs stable at a 25% overclock (Orthos, S&M, anything) and I haven't even tried higher because of the trouble I'm having with temps even at stock.
