10x if AMD hasn't changed there model numberingQuote:

Looking for a cheap platform to replace my ageing XP-M with until a worthwhile AMD dual core chip (>2.5GHz+) is available...
atm all mobile a64s are 754, dont know if turion will be 754 as well, but i doubt it.
and since turion will probably replace mobile a64s sooner or later there wont be 754 90nm chips for much longer, but for at least half a year if not longer.
dont know what the highest default clocked oakville will be, but a good 90nm chip should reach 2.6ghz+ on air easily. this is perfect for a cheap yet very powerfull system!
just watch out and make sure you get a 90nm chip with 256kb l2 cache or even 512kb l2 cache! i heard some oakvilles will only have 128kb l2 cache.
hmmmm if we are lucky there might even be 1mb l2 cache 90nm 754 cpus ahead... but im not sure...
Keep we informed :)
But CBBID ... I think that is not very good :(
I can have Oakville since Decembre 2004, but 260 € ... and my A64-M 3400+ 62W CG runned @ 2.7 GHz @ 1.65V (1Mo), so I haven't buy it.
Now I have Winnie 3000+ CBBHD 0450 WPBW : 2.84 GHz @ 1.49 GHz rock stable ... maybe I will go on S754 if Turion is ok @ 3 GHz :D
Good luck :)
That's a really good Winnie. :)
OK, now that I got enough sleep and let this thing prime for a while, I can say the following:Quote:

My goal was to hit at least 2.5Ghz with this chip and I sure got that. Primed for a few hours at 2.5Ghz without problems.
Unfortuately my chip doesn't seem to be a wonder chip, as the one mentioned before.
I primed at 2.5Ghz with a vcore of 1.65V, just to play it safe. Well, 2.4Ghz wasn't stable at 1.4V ad as it was already very late and I didn't want to try a lot of settings, I just set the VCore to 1.65V, the FSB to 250 and the multi to 10x and let it prime along.
Further testing will determine what more is left in this little chip. All in all, I'm really happy that I bought that thing, because I think it's well worth the 97,-EUR (~125,-$) that I paid for it.
I'll keep you guys updated on any changes.
Got a screeny of the 2.5Ghz in the attachment.

Sweet. 1.65v is definitely probably more than is neccessary. If you keep tweaking I bet you could get it down to ~1.5-1.55v at 2.5GHz.
Even if you don't have a 2.7GHz-on-air-Winnie, just consider that mine can barely hit 2.3-2.4GHz. Might make you feel better. :D
Thx, I know. That's exactly why I'm already more than happy with the 2.5Ghz that I got easily now. ;)Quote:

Winnie 3000+ = 1.8 GHz (Max = 9x).
Oakville 3000+ = 2 GHz (Max = 10x).
Where have you buy it for 97 € ??
Oakville 3000+ cost ~ 180 € in Europa !
Wow $125 for a .09 S754 chip is awesome! Anybody got some impressive results like 3 GHz on air yet? :D
chilled water? please post some more results and an orb link to 2005, i find it hard to believe that 2.85ghz is stable with 1.5vQuote:

I'm with you Ivan, for $125 this would be a very good option instead of getting a 939. :toast:
I could get a mobo and CPU and not think twice about about another upgrade in a few months. :banana:
$125 USD for a mobile A64 chip?!!!
I could pair it with the DFI S754 board that costs £70... :D
This site sells 2800+ Oakvilles for $112.

Only problem is when I emailed them and had the sales guy check their stock, it was all old steppings and weeks (like 24 and 27), so it would be good for an SFF/HTPC, but not somebody wanting to overclock. My 2800+ that I got off eBay is a week 30, and it overclocks :banana::banana::banana::banana:ty enough already. I can't imagine how much of a flaming turd a week 20 Winnie would be. But he mentioned something about being able to custom order "any mobile or desktop Athlon64." So you could try asking them to order another 2800+ or 3000+ from their vendor. Chances are it would probably be a newer week. I corresponded with the guy via email and he was very polite. And I'm thinking when Lancaster comes out, these people might be able to hook us up (because if it's like the current mobile situation, none of the major etailers will be carrying them).
BTW, I think I'll try to get a recent Clawhammer CG 2800+, just to see, what these new CGs are capeable of. And of course the 1MB L2-Cache on a cheap CPU are very tempting. Now that I know that it's not the board keeping me from a high HTT. :D (my old Clawhammer C0 could do about 2,7GHz for sure, but the memory controller craps out at about 260MHz :( ).
Got my sempron up and running. Did a quick run through with just vid card, and I could get up to 320 HTT (what a gem of a board) went for 325 to get 2.6 ghz, but it would lock during boot up (more voltage needed or maybe CPU limit) the other possibility is the HTT speed is getting too high. I dropped to 3x at the start for OCing, and at about 290 I dropped to 2x to play it safe, however it would reset to defaults when I used the 2x multiplier so I upped back to 3x to see how far I could go, and for boot up 320 was the limit. I'm now installing the HD and DVD burner and will put xp on it so I can do some real stability tests :) but so far so good :banana: :banana: :banana: Stepping info: 0503 CBBID
How many volts for 2.56GHz?
unfortunately its not stable that high, looks like the semprons clock about the same as winchesters, I can get about 2.5 ghz at 1.55 V for prime stable I can probably do 2.6 ghz but not prime stable
Yeah, it seems that the "better" steppings all start with "CA"... so "CABID" would be better i suppose. Then again, I might be wrong. I have little idea of what these 5-letter codes actually mean.Quote:

From what I've read, the best Winchester stepping seems to be CBBHD, mid to late week 40. Then from week 50 on it seems to have all gone downhill. :(

Insane results there dude. Too bad it's not an Oakville so kinda offtopic :p
Hmm, my CPU doesn't seem to be very good. Seems as if it needed 1.75V for 2.6Ghz and about 1.85V for 2.7Ghz. :( Well, 2.5Ghz isn't bad, but not the best. But the price was just the BEST ever. :D
I know why the CPU isn't that great of a performer. It's number 83 in the particular production run, and the CPUs with lower numbers nearly never are great for Overclocking. The later ones tend to be better most of the time. Well, you can't always get the best, especially the best for the lowest price. :toast:
Don't feel too bad. Those results are still good. It's just too bad you couldn't have got your hands on a mid to late week 40. :)
