XP2500+ hit its ceiling?

I finally got a decent fan to put on my Primary's SLK-900A, a ~60 CFM Enermax 92MM unit. Even with 60 CFM though, this processor is only doing 2.2GHz (200x11) at 1.875 VCore and running at 48C. That's too much for me, and it hard-locks at 200x11.5 - any suggestions?

    some info on da memory plz

    I wouldn't suspect of the memory in this scenario by the simple fact that the chip is requiring almost 1.9v to do 2.2GHz.. Which is pretty atrocious for a Barton, but not entirely impossible.

    Do you have the stepping of the chip?

    What bios version are you using?

    I've got the stepping in a text file somewheres on one of my PCs... I'll post it when I get home.

    The memory is not a factor, except that in order to run synch I can't go more than 200 FSB because it's PC2700 RAM, But when I first OC'd the Barton I was running the RAM at stock PC2700 speed.

    Funny thing is, this same chip was stable at 2.2GHz at 1.825v on the old DFI board I had, with the same PSU. Still, I'm rather disappointed in this chip since my XP2100+ cranks away all day at 2.3 GHz at a cooler temp at lower VCore and 10 less CFM on an SLK800A...

    That's a weak 2500, my old 2500 did 200x11 @ 1.65vcore (stock). No problems prime95 stable.

    Tried bumping fsb over 200 @ 11 multiplier?

    Tried re-seating the SLk900?

    I'll try reseating the SLK900, and I can try to up the FSB, but I don't plan on keeping it that way, since I can't afford new/better RAM, and the timings are loose enough at 200 as it is, I don't want to drop them below the current 7/3/3/2.5

    Yes, it's a weak 2500.

    I'm using whatever version of BIOS shipped with the mobo... will a newer BIOS affect the OCability though?

    Yes a new bios will. Also change the timings to 11/3/3/2.5 should help with bandwith.

    I thought that lower #s were better in mem timings tho? When I try to set it to turbo mode (which the RAM can't do at 2.7V) it makes the #s 6/2/2/2...

    I'll update the BIOS and see what that does for me.

    For the nForce2, 11/3/3/2.5 is better than 1-10/3/3/2.5

    Optimal is 2/2/2/11.

    Well! I learn something new every day... I can't wait to see how that increases my PCMark score!

    So I shouldn't be trying to set that thing at 6??? Hmmm, I'm with Ghoosdum here. Should I leave mine though if I'm doing 2/3/2/6??

    x/x/x/11.

    Period.

    Fill in the Xs with whatever else your RAM is capable of doing. Be it 2/3/2, 2/2/2, 3/3/3, 2.5/3/3... Just end in 11.

    Why 11, Thrax?

    Will it work on any speed DDR? I'm at 2-2-2-5 @ 400, because my Cpu is running at 200x11. I've finally decided to try to get a little more out of 2500+a7n8x, since it's been quite stable these past few weeks.

    Lets say I were to reach 217x _ , should I stick with Corsair's recommended 2-3-3-7?

    2-2-2-11 will always be the fastest on nforce2 platform if your memory will handle it. It's only a *tiny* bit faster than -5 or -6 but -11 is indeed faster. It's been tested a kazillion times all over the internet, Thrax has verified it on these forums, a number of other members including myself have verified it on our systems.

    No one knows why x/x/x/11 is faster than x/x/x/1-10, but it is. I chalk it up to the way the nForce2 memory controller handles its cycles.. 11 must just strike a chord.

    This works on any DDR module in existence.

    I just needed 1 reply as an impetus.

    2 just sealed it.

    Going to test it now :)

    Def flash to a newer bios! I know i am using 1.8 and my old 2500 got too 220 FSB

    A great majority of bartons, like mine, hit 11X200 easily at stock voltages. Must be you have a bad chip or something. Although i would think even a bad chip would do better than that:(

    Here's the stepping, let me know what you think of it:
    axda2500dkv4d
    aquca 0323tpmw
    And it's #231 in the batch :(

    Never heard of that stepping. Flash the bios (you can do it in windows now, you know, so you don't have any excuse :D) and see if that helps.

    If not, I'd say that you just have a really rotten chip.

    I'll update the BIOS as soon as I switch over to that PC - I'm using my secondary right now and I can't put 'em on the KVM switch because my LCD monitor has DVI input...

    Since my primary has no floppy drive, would you guys recommend using Abit's GUI BIOS tool for the update?

    I'd just use FlashMenu or whatever its called, yes. I've used it before without a problem.
  • ThraxThrax 🐌 Austin, TX Icrontian
    edited December 2003
    Yeah. Almost everyone with an NF7-S here has used FlashMenu without a problem.

    I swear by it.

    Now, of course, the next person that uses it is going to fry their BIOS...

    It's pretty easy. Just make sure you don't have anything running in the background and click "one click live update" or something along the lines of that. I've used it with no problems at all.

    Searching around Google, I've found several threads on other forums that relate AQUCA Bartons made earlier than yours, GH, that are doing 2.4 and 2.5GHz.

    Maybe it's time to look elsewhere; but I wouldn't get worked up over finding another culprit, you might have just gotten a worse-off one. :(
