Ever heard of a weak OCing TBred B?

Just slapped in the TBred B-1800+ (Stepping is written down at home) and started ocing it. Couldn't get over 2GHZ!!! That is a b*tch. Got 9.5x210, but the thing won't post higher than multi 9.5, even at stock FSB. That seems weird to me, any ideas??

1.995 instead of 1.53 is ok i guess, but I had hoped for much more.

It's also that new packaging with the translucent material that you can see what appear to be pathways below (looks like a tiny motherboard)

  1. What heatsink? Temps? Voltage?

  2. Heatsink is a Thermalright ax-7 with Vantec Tornado (holy balls is it loud) and temps are 38-39 degrees under load, 34-5 idle. Stock voltage is 1.6 or 1.65 and going up to 1.8 made no difference in my MSI K7N2 Delta
  3. Bummer. Your temps and cooling look great and your voltage should be plenty for a great overclock.

    One thing though, what does your BIOS report for Vcore voltage? I need 1.8 volt for my XP1700+ to reach 2.1 Ghz but the reported voltage is 1.82 volt. A setting of 1.775 volt (reported as 1.79) only allows me to overclock to 2.0 Ghz. I can even get to 2.0 on 1.70 volt but anything higher is like brick wall. 2.25 Ghz is possible for my chip but I need 2.15 volt (my mobo can go to 2.25 volt) to do it.

    What I am saying is for me the first 533 Mhz of overclock needs only a +0.10 V increase. The next 100 Mhz needs a second +0.10 V. 150 Mhz beyond that needs a whopping +0.35 V higher still.

    My XP1700+ is a Tbred B JIUHB 0302 DUT3C.

  4. whats the stepping production date and default voltage?

  6. Hell Yeah!!!!

    I don't know WTF I was doing wrong yesterday, but I cranked up the voltage to 1.8 and I'm typing this on a 2300 MHz TBred!!!! I am relieved to have found 300 Mhz. It beats the Barton 3200 in the SiSoft Sandra CPU Benchmarks. Sweet. Thanks for the help, fellas. You guys are awesome.
  7. What vendors do you buy from, that list the stepping numbers? I've been searching for a cpu with a good stepping and I guess I just don't know where to look. Thanks for the help!
  8. Sorry, I don't know any vendors that list steppings.

    I usually just buy from newegg.com but they don't list steppings/batch codes. When I ordered my Tbred B 1700+ back in February it was pot luck. Some people got Tbred A's some got B's. I hear (or rather read in the customer comments) that some Newegg customers still occasionally get Tbred A's when ordering XP1700's. (Don't know where they are getting them).

  9. Amd is reproducing some tbred A's aparently, because they have new production dates, the only reason i can think why is possibly tbred A's are cheeper to manufacture?

  10. You might have picked up that info from me. I posted regarding some recent date Tbred A's being spotted.

    However, the idea that AMD might start manufacturing Tbred A's again always bothered me. Wouldn't they have to retool just for that purpose? It just doesn't make sense that they would do this.

    Just recently I ran into <A HREF="http://www.xbitlabs.com/news/cpu/display/20030503024652.html" target="_new">Xbitlabs' article on CPU remarking</A>. The article is about 5 months old but this was the first time I saw the story.

    Here's a little more recent article.

    I'm not saying any particular vendor is guilty of CPU remarking. It's just scary stuff.

    I wouldn't have spotted some of those alterations.
