0449 MPM 3000+ winnies may still be available...

[Valhalla]

Didn't know if anyone would be interested in getting one of these, since Venice is about to drop, but I thought I'd share with everyone anyway.

I found a local store in Castleton, Indiana called Computer Renaissance (317-842-2000) that had 3 of the 3000+ Winchesters with the 0449 MPM coding in stock for $199.00 each. This was two days ago, but they don't look like they move stock very quickly with local buyers - maybe due to price?

Looking through XS threads, it appears these may be good to stellar overclockers - do your own research and see what you think of the OC results others have gotten with this chip. Week code of 0449 is nice and "M" appears to mean re-speed binned parts - don't completely understand this, but maybe higher speed capable parts marked as lower speed units?

I purchased a 3000+ 0448 SPMW from them about 10 days ago. I'm still getting parts together for my new rig, so I won't know what the chip will do for a while, but these look like good chips from what I've read here - so I'll keep my fingers crossed.

Just ordered two 1 gig kits of TwinMos PC3200 ram last knight from Newegg, hoping to get some good UTT ram. If Venice pans out to work with 4 sticks well, then I can upgrade at some point and have the ram ready.

I've read many posts about guys not finding any of the "good" weeks anymore. We don't know yet whether or not Venice will be more closely speed binned by AMD. If they are, the OC's on the lower end 3000+ and 3200+ may not be what we hope - or maybe they will be.

Anyway - thought I'd share the store and phone number - Good Luck!

valhalla from nvmax?

No - different guy. I'm new to the OC forums.

In the MPM the first M means that the assembly lots have been combined and not made on one specific day thats all. The second M means that the fabrication cores came from different batches too. The lack of a W at the end means that wafer lots used in the process could be mixed. Nothing to do with "speed re-binning". The P is for the assembly plant of Penang.
The CBBHD or CBBID fabrication stepping is way more important.

Interesting! I've been looking for information like this for a VERY long time. Is there a chart in existance that tabulates all the letters with their meaning? If not, would you mind posting additional information so one of us could make one?

[Valhalla]

Thanks for clearing that up so eloquently, OC Detective. So, MPM would not be a necessarily "better" or "worse" marking than any others I take it. What about the 0448 SPAW chips - does the fact that they are marked SPAW have anything to do with their great average performance, or is the 0448 silicon more of the reason?

[OC Detective]

No the SPAW I put down to falling within the normal distribution pattern of what to expect when overclocking. We have seen perhaps only 4 or 5 of these exhibiting better than average overclocking however this may not be down to the stepping rather the users capabilities and their systems. S means Tuesday, A means using the first batch of cores used that day for assembly.

[OC Detective]

I posted up a link on decoding this information many many moons ago only to be rudely told that EVERYONE already knew this information....

First Digit is either R through to X for Monday to Sunday or A through to G for same. M means mixed assembly lot.
P merely means Penang
3rd digit is the sequential batch of cores used in assembly - so if they are using the first batch for that day its an A second batch is B and so forth. M means the cores used in the assembly came from different batches.
The existence of a W for the 4th letter means mixing of wafer lots in the core fabrication was prohibited. Its absence means the wafer lots could be mixed when making a batch of cores.
0450 etc is self explanatory and is the week of assembly.

[Valhalla]

So - R is Monday? S = Tuesday? T = Wednesday? What about other alphas in the first position such as "X"? Do they correspond to other days of the week? Also, do you know whether or not being an "A" batch is better than the following batches (B,C,D, etc) or does that remain "luck of the draw" in terms of the OCability of the chip?

[fareastgq]

I have a cbbhd mmpm 0449, most likely you can do 2.6 at 1.4 volts That's what I've been able to do with initial benching on the retail cooler. The decoding of the stepping and other letters on the cpu is the same as the bartons and such before, it's just a way to tell when they were made. And it tells us how much better of a chance we have for a good chip, that doesn't really mean it WILL be good, just that it's more likely to perform like others with the same markings. AMD has a chart to decode all this, I don't have a link to it, but I'm sure if you search enuff on these forums, someone has it posted

[OC Detective]

The 3rd digit and selection of core batches is not entirely random but there is nothing on the batches when they arrive in Penang on reels from Germany to indicate that one batch of cores is better than another. Whenever possible in assembly they will try to operate a FIFO system.

[Valhalla]

You seem to have a great handle on the code meanings!

No, not everybody knew what the codes were telling us - so thanks a great deal!

One additional question - do the four digits at the end of one of the strings of alphanumeric information have any significance on performance? For instance, my 0448 SPMW has the last four digits of 0088, which I understood to be an early batch(?). Are early batches better for possible OC ability or is it once again "luck of the draw/silicon"?

[Valhalla]

Thanks for the info, fareastgq.

If you are doing 2.6 at 1.4 volts, isn't that a good overclock right there? What might you get if you bumped up to, say 1.6 volts? From what I've read, getting 2.6 at around stock voltage is not bad at all...

[OC Detective]

Its some form of serial number possibly combined with manufacturing lot numbers for the cores and wafers or even purchase/delivery order number from Germany to Penang and based on what I have already stated is extremely unlikely to have any bearing on overclockability. The 88 could just be the 88th assembled cpu from the batch. Although 8 is a lucky number in Chinese!

[Valhalla]

I had read that an earlier number, say 0088 versus 256 was "better". However, I'll take lucky 8! lol!

[Mats]

Yeah I've read the same too. Have checked a lot of numbers and found out that many FX (though not all) have a low number, while many Semprons have high number. They are different cores, but it might tell us something about it anyway.
Maybe lower number = closer to center of wafer? I don't know how many cores you can get out of a (200 mm??) wafer.

My 0449 CHBBD 3200+ w/ stock retail cooler does 2500 @ 1.4v (24/7 usage), 2600 @ 1.55, booted @ 2700 but seems like it needs 1.6v+ to be stable. Gets too hot for my box w/ the stock cooler at that much voltage.

Seems like they are good chips. Worth checking out.

[magg]

Wow that makes me feel good, I just finished putting together my system 4 days ago w/ a 3000+ 0449 MPM, and I hardly saw anything around a lot of forums that had that code. Nice to see that you guys can clock so high on such little voltage.

I'm tired of waiting for the AS5 to sit in, after seeing this post, I think I'm gonna try OC'ing right now

[dnottis]

Prime and Super PI stable -


And 1:1 2T on Neo2 Plat.

Hmmm thanks again OC.D

I for one think information like this should be stickied
