    Which one K6-2+600 or K6-3+550

    I have a PowerColor P561A (aladdin7) with a K6-3+450 oc'ed to 550 default voltage and a vantec heatsink. I have another system that I am using for spare parts, that has a K6-2+500 that I have been able to oc in the past to 600mhz. My question is which one do you think is faster and should I swap processors?

    BTW, I'm keeping the PowerColor. It's a oddity kind of like the edsel.

    I'd probably say the k6-3. But how much faster then 600 can you get the k6-2? You might just benchmark them, and see which one is faster!

    I think the limiting factor is the PowerColor motherboard. When I overclocked the K6-3 the system was very unstable at anything above 100 fsb. I got it to load windows at 6x100 (2.1v), but it would reboot after 5-10min. Maybe with better cooling I can do better, but I don't know of any good heatsinks that fit a socket7.

    Where can I get some good benchmarking tools?

    Bob, any word on that alienware PC? I'm averaging 11 post a day, in a year that comes to over 4000 post! Do they have a prize for ultimate status of the week?

    No word yet. I'm wanting the Blue one! It goes best with my room I'll have to talk to Gus about this soon if he doesn't ask which one I want!

    It sounds like cooling is the problem. I don't know of any super socket 7 fans either. Do a search at google.com for it. Maybe you'll dig something up.

    As for the benchmark tools I'd go to somewhere like cnet or something. I'm at my colleges library so I don't have my links at the moment.

    They're very close. The K6-3+ would clobber a regular K6-2 at any speed, but the K6-2+ clocked at 50Mhz higher would be a very formidable opponent. I'd still say the K6-3+, but only by maybe 5%.

    Yeah, any board with that Alladin7 is a keeper. that 1/4 PCI divider for use with the 133 Mhz bus is sweet.

    I'd run CPUMark 99 on it-that'll give you the best idea of raw CPU power between the two. Should be a real close one!
    *K6-3+ 450@550, AOpen AX59Pro w/1MB, 256MB Mushkin Rev3, V3 2000 PCI, WD 20.5GB-7200, LG 32X, HP CDRW, ZIP 250, Muse XL

    *K6-3 400@412.5, AOpen AX5T-2, 128MB Micron PC133, Creative Banshee, WD 17GB-5400, Hitachi DVD, DXR2, Zip100, Yamaha DS-XG

    Well here are the results from Cpumark 99 and it wasn't even close.

    K6-3+@550: 53.2
    K6-2+@600: 42.6

    The larger cache on the K6-3 really makes a difference. I would like to see if I could hit 600 with the 3, but it's going to take better cooling. It also seems that the fsb jumpers above 100 are broken. Even if I underclock the multiplier and set the fsb to just 110 I get a blank screen. Boy, if only Asus or Abit had come out with a aladdin7 board. I'm sure they could have gotten it to run at 133.

    My last system was a k3 450+ witha dfi board and it did 550mz was a great system1 wish i was able to not sell it , but my KT7 Raid and duron 700 at 1050 mz was a huge jump! I don't think upgrade all the time is worth the money! My present system has most bugs worked out and I upgrade for nothing by using the best drivers, The raid set up was a fun upgrade, I am using two quatums AS 7200- no noise- 10 gig each at raid zero. I just tried a new driver for the 370 highpoint- the 2.08 driver and I am using yp for the kt7 bios-lost my data with 3c bios and do not reconmend updating if you have no real problems , but it is fun to try just back up everthing, Windows xp seems to me to be a expensive upgrade- I am running windows ME- its okay but burns up my memory- 448mbs worth. I us computer to surf and burn mp3's. Not really into games.

    Have you raised the voltage while trying to overclock the k6-3+? 2.1v may not be enough to run it at 600. It may need 2.2 or even 2.3. According to coolermaster: http://www.coolermaster.com/home.html they have grouped all of their socket 370, A, and 7 heatsinks together so I would imagine any one of them will fit a socket 7.

    Looks like the first three on their list will work with socket 7: DP5-5E11, DP5-5F11, DP5-5F51.

    Thanks for the replies guys.

    Yes, I have tried the 2.2v setting didn't dare go any higher. I really think it's the motherboard. PowerColor was never known for making great boards, they mainly produced video cards. Anyway, this combo is going into my nephew's machine so I won't be doing anymore overclocking with it. I want to make it nice and stable so he doesn't have to come back asking me to fix a problem all the time.

    K6-3+ is faster than K6-2+ at same speed...
    my suggestion would be k6-3 450@550 Mhz (600 works)

    just remember that these old AMD DONT like FSB clocking
    go with the multiplier instead...

    Socket 7 mobos only (mostly) support up to 5.5x multiples
    but K6-2/K6-3 will take an multiple 2x as 6x

    So set it at 100x2 and you´ll have 600 Mhz
