    Finally - A decent T-bred overclock!

    http://www.vr-zone.com/#2324
    http://www.piopioshardware.com/AMD/013u/tbredtest1.htm (Edited - link crapped out, now pics on my webspace)

    AMD 0.13u Thoroughbred 1800+
    (AXDA1800DUT3C AIPCA0208TPBW)
    Default VCore 1.6V
    CPUID 0680
    266Mhz FSB

    EPoX 8K3A+ (24/03 Bios) and IWill XP333-R (11/04 Bios) motherboards are able to detect the Thoroughbred correctly. By setting a VCore voltage of 1.95V on the IWill XP333-R, Thoroughbred 1800+ (1.533Ghz) is able to overclock to 1.9Ghz air cooled while a VCore voltage of 2.15V on the EPoX 8K3A+, a max clock speed of 2Ghz is achievable. However, a clock speed of 1.9Ghz is stable passing all the benchmarks like SuperPi, Cpumark 99, SiSoft Sandra 2002, PCMark 2002 Pro and 3DMark2001.






    1.95V. Hmmm...

    MuFu.

    And these are the low speed babies. Think of what the 2200+ are going to do. I think they should hit 2Ghz easy with a few hitting 2.2Ghz of more after a few steppings. Think of the first Palamino cores. They launched into the MP market at 1.2Ghz and could not overclcok much past 1.33. Well obviously things have changed as they are at what 1.73Ghz now (or 1.8Ghz soon likely). By the time this core matures, you might see overclcoks in the range of 2.3-2.5Ghz. Then comes Barton and the MIGHTY HAMMER!!!!

    49c isn't that bad considering it's a 0.13 with 1.9v. I wish they gave more temperature readings, but all their text is filled with ???????????????????
    Either way, it's an early model low-end t'bred with a good OC. Those 1.8ghz chips could be interesting. Maybe now we can finally quit watching and start playing.

    Aren't those default numbers a little interesting? I mean a default of 1.6 volts for the .13 part? Wasn't the XP 1800+ defaulted to 1.7? I would have thought there would be a larger difference.

    For the first stepping, the overclocking results appear good, however. 1.53 - 1.9 is pretty darn good, but what concerns me is the use of 2.15 volts to do it.

    I'm not certain that overclocker did a decent job. His Multiplier was at 10 X and FSB was at 200Mhz.

    It looks like his RAM was maxed out. I would have like to seen him unlock the chip.

    If they can be unlocked.

    200MHz is 400MHz DDR! KT-333 chipset, don't forget...

    I agree that 1.9GHz on air is very good for an early stepping.

    That is a rather impressive overclock for an early stepping. It least their default Vcore starts lower then the Palomino and T-birds. That means 1.85 on most boards will do a lot more as long as they are cooled properly.

    Mufu,

    Thanks for hosting those pics. They already exceeded their bandwidth.

    Take a look at their RAM. It says PC2700, which is DDR-333, right. So, if they are cranking their RAM up an additional 66Mhz, it may be possible that the extra FSB speed is killing their overclock. If they are able to connect the L-1 Bridges and set their multiplier to 12.5 X maybe we could see 2000 Mhz stable.

    I was expecting to see 2100 Mhz from that new .13 micron die. Sorry, I expect alot from AMD.

    Here is the P4 @2.4Ghz for comparison.
