1800+ Thorougbred - NOW $59!! shipped - Now $67 argg.

[formulav8]

Just updating this old thread. I did receive mine awhile ago when I payed $69 for it. I can easily get 2ghz out of it at 1.7v 100% stable. I will crank it up more when I get my copper hsf. But there are others that can't get that high. I guess it is a hit or miss type deal. Pretty much everyone is getting around 1.8ghz as the lowest oc.

Bump for edit. What do you guys think??

 

[DEFIANT1]

Hmmmm.... To replace my free, AMD-supplied 1800+ Palamino with a Thoroughbred or not.... Decisions, decisions!

Looks like a smokin' deal!

 

[SonicTron]

I doubt this is a rev B chip, about 2ghz is the average overclock for the rev A chips anyways. A rev B chip should be seeing upwards of 2300

 

[formulav8]

The reason OC.com is giving is voltage and the letter U in the cpu code.

The 1800+ is: AXDA1800DLT3C

The 2400+ is: AXDA2600DK3VD

The stepping and week for 1800+ is: AIUGA 0242SPCW

The stepping and week for 2600+ is: AIUGB 0244SPDW

Could what I have in bold letters tell us the revision?

 

[DestruyaUR]

NOT a Revision B - overclockers.com covered this. Revision As will have AXDA1800DLT3C, whereas Rev. Bs will have AXDA1800DUT3C. Still, ya never know.

 

[formulav8]

These seem to OC fairly well. Another guy got his to 2ghz without a problem at all.

A buddy of mine, Rockhammer, got a free 2200+ at the AMD Xpp II roadshow. His is watercooled but he got his week 36 revision A to 2250. Not a bad OC for a "A".

As I understand it, rev. B is made at a 0.13 fab, and the A's are older tech at another fab. At some point they will probably move all CPU fabs to the new process, but for now you could concievably have an A newer than a B. Date is not necessarily a good indicator.

Actually, date and stepping are an excellent indicator of how good a chip will OC. They are the result of improved yields and fab processes over time. Both the A's and B's are on 130 nm fab process, the difference being the B's have more layers on the core resulting in improved transistor performance. The technical jargon is over on the 2400+ review page.

I was looking at this today as well; the stepping and date is certainly a far cry from the AIXXX or ARXXX steppings seen on the 1700+'s and also the ~week 24 date of the 1700+. Both the stepping and date are more in line with the 2400+ and above CPUs. I'd test it out, but I already got burned when the 1700+'s first came out. Until then, I'm gonna wait until OC.com's theories are proven correct or incorrect.

AXDA1800DLT3C

L stands for operating voltage where M=1.75; K=1.65V ; U=1.60V ; L=1.50V

Now,
M=Palomino
K=T-BredA
U=T-BredB

is L also T-BredA only then...??

By the way
AXD stands for AMD Athlon XP Processor Model With QuantiSpeed Architecture for Desktop Products;
A ? for ?desktop processor?;

D ? for package type, D stands for OPGA; What's OPGA and what's the alternative code??
L ? for operating voltage: L=1.50V, U=1.60V, K=1.65V, M=1.75; [L=T-Bred[b]??[/b] U=T-BredB ; K=T-BredA ; M=Palomino ;]
T ? for critical die temperature: T=90 degrees Celsius, V=85 degrees Celsius;
3 ? for size of L2 cache: 3=256KB;
C ? for Front-Side Bus frequency: B=200MHz, C=266MHz, D=333MHz.

The 1800+ tbred @ Newegg are indeed A chips. I have one running @ 1.970 mhz @1.9 across the room from me. There nice but not revision B chips.......goldie

 

[ziptree]

1.9V, what mobo do you have? I have a msi kt3 ultra2 and it'll only allow +/- 0.1V of the default voltage...the t-bred core is 1.5V, so i can only pump mine up to 1.6V. =/ doubt its enough for a successful OC.

 

[goldie1]

Ziptree,

I've got a Abit KR7A-133R. I also have a voltage mod kit which is a resistor that allows me to dial up my voltage. Its a potentiometer, a small hook w/ a screw dial attached to power chip on my board. I just go into my bios and adjust the voltage to where I want it.
I was able to run up to 1.875 mhz @ 1.65 volts if that helps..........goldie

 

[hasu]

Among the Rev.A and Rev.B TBreds, which one will run cooler? Any idea?

if you connect all the L11 bridges, you should be able to go up to 1.850 again on your mb. epox boards generally allow up to 1.9-2.0v. i connected my bridges, but i don't think i did it right, but i can get up to 1.8v now on my kt3 ultra. i'll probably try again to get 1.85 by redoing the bridges.

c627627 ... Thanks for all the coding info, I love this forum, now I can impress my friends with info I stole, um, barrowed, from an Anandtech forum.

L stands for operating voltage where M=1.75; K=1.65V ; U=1.60V ; L=1.50V

 

[ThumpR777]

Just a guess, but I believe the Rev. B may run slightly cooler. The extra layer was to facilitate the flow of info through the chip. It is possible that the restricted flow of the 2100 and 2200 especially, was the result of resistance. Less resistance will equal less heat. Thats my theory and I am sticking with it.

L stands for TBred A, as can be seen here: "How To Tell Them Apart"

[gogovs]

I don't thing so. It's revision A.
still waiting for rev.B

 

[formulav8]

bump for price update.

 

[dshodson]

what is a decent heat sink/fan to buy to use this thing from newegg
i dont want to set any oc record but would like to get close to 1.85 or 1.9 or so

[EXman]

interesting thread....

I might need a replacement for my 1400 T-Bird. Anyone know if I can use a 2200+ on an Iwill XP 333? I just want to max out this mobo with a new chip.

I love my mobo so I really want to change just my processor even though 1.6ghz seems fine for what I do.

 

[formulav8]

I believe I saw people running the .13 cpu's over at amdmb.com forums with that board. Head over there and see whats going on.

 

[The Sauce]

So it looks like you could probably just pop this sucker in at 166 FSB and get 1.90 Ghz without having to unlock it...that would be nice.
