  • PIII 650e Overclocking?

    What are people's experiences with overclocking this processor? I have both an ABIT BE6 and a BE6-2. WHat may I expect? Guyver???

    With with PC133 or good CAS 2 RAM PC100 RAM, a video board that doesn't mind running at 83 MHz, maybe with a bit of a voltage tweak, and on a nice stable motherboard, I think 806 MHz should be obtainable.

    I bet you're looking for a higher number.

    I just happen to be finishing up an article about overclocking the 600E. I run it at 744 MHz, without voltage tweaks or super-cooling solutions. By raising the voltage up to 1.70 (from 1.65 volts), I got it stable enough to play Quake 2 and 3 and run the SETI client for long periods of time. 3DMark2000, however, crashes to the desktop. I suspect this is my videocard objecting to the overclock. I didn't see anything that vaguely looked like a cooling issue.

    I don't think the Coppermine was originally intended to run much higher than 800 MHz, although it appears AMD has force Intel to make some changes in their roadmap. Intel, apparently, has had yield issues with Coppermines clocked at 800 MHz and higher, which contributed to some of the delays.

    Of course, this is all a crapshoot. You may get the proverbial wonderchip or you might get a dud. I wouldn't expect to get a heck of a lot higher than 850 (6.5x133=864) until Intel implements whatever changes necessary to get the Coppermine that high at spec.

      One part of the problem is whether or not I have a chance at a 133 fsb on the BE6 board. I'm currently using the BE6-2 board and am getting a stable system at 126 MHz fsb (819 MHz). With the voltage at 1.70, I can get to 128 (832). I remember Guyver found the BE6 better at ocing than the BE6-2. His thread dissapeared. I was interested in his experience with this combination also. For safety sake, I am running my system at 813 Mhz (125 fsb).

        Sorry guys, I was away for a funeral... Leukemia is a bitch... Lost a cousin to it before Christmas, and my GF's uncle passed away last Saturday due to complications with his 2nd round of Leukemia.

        Anyway,

        With the BE6 and good PC133 cas2 RAM you should be able to easily attain 866Mhz...

        Caveat #1 - BOXED PIII-650E (not OEM) - OEM's are not quite up to the grade of the BOXED processors (usually)

        Caveat #2 - Cooling and Voltage settings. I have always run stock voltage, and I always use additional cooling. In this case I went to the larger Alpha cooler. The BE6 is the better of the 2 boards for this due to memory spacing from the BX chipset.

        Good Luck, and keep us posted on your progress..

        Guyver

          Guyver - Two questions:
          1. How did the BE6-2 do with your setup?

          2. What is the difference between my Alpha P3125 and your P3125S?

            #1 I haven't had a chance to try it yet. Things have been real hectic around here the last couple of weeks.

            #2 I'm thinking it's just a rev of the cooler, and may just mean that it came with the fans attached. I don't think there's much difference.

            Once I get a chance, I will try the BE6-II again...

              I thought, in a previous thread, that you said the BE6-2 was inferior to the BE6 for overclocking. Also, if memory serves, ocing of the 650e was the issue which made you believe this generalization. What did you do to come to this conclusion? I can't find your previous thread.

              Thanks for the info.

                On a Abit bf6-2I manged to get my processor up to 728 from 650 without any Voltage changes. If I had better cooling and memory I probably could go higher.

                  The BE6-II that I used was used with my old PIII-700 that wouldn't OC worth a hoot. I was able to OC the PIII-700 higher with the BE6 than with the BE6-II, higher still with the P3C2000, but that was at a lower performance mark. Now that I've got the PIII-650E, I'm thinking of trying the BE6-II once again just to see if it was the 700E that was causing the trouble, but I doubt that it was all the 700E. I still have a significant gut-feeling telling me that the BE6-II isn't up to par with the BE6, but that is unsubstantiated at this point in time.

                    I can verify that the BE6-2 wouldn't overclock as well as my old BX6-2. I am going to substitute the BE6 in a couple of weeks once I get back from Chicago. I'll try to find this thread once I return and post my results on the 650E (It's a retail processor).

                    Thanks again

                      The more I think about it, the more I don't want to have to take my rig apart, AGAIN, and change out the mobo just to be disappointed, AGAIN. Maybe I'll leave well enough alone, until the next Gen boards are available...

                            I'll try this weekend... It is my birthday today, and the GF has to let me do what I want this weekend... Which would you choose (note: she's sick at the time, so that's out you like-minded individuals! )
