    Place your bets folks: P35 v. 680i

    For reasons too complicated to go into, I'm just setting up a rig with an RMA'd P5N32-E SLI and an E2180. I already have an E2180 in a P5K-E, which is fully stable at 3.15GHz (can't quite keep 3.2 going). So...


    On my left, in the red corner:

    E2180
    Asus P5K-E (P35 chipset)


    and on my right, in the blue corner:

    E2180
    Asus P5N32-E SLI (nVidia 680i chipset)


    Both are cooled by a Thermalright Ultra120A cooler with a 120mm fan. Sadly, can't remember what types, but I'm willing to swap them in the event of a close tie. Both are in Antec SOHO 1040 cases, with an Antec Truepower Trio 650W PSU and 4 x 80mm fans. The rest of the gear is slightly different, but not by much:


    Red: two 80GB HDDs in RAID0, BFG 7900GT

    Blue: one 80GB HDD, no-name



    Theory says the P35 is a better overclocker than 680i. Both will be kept at default multiplier (x10). So wants to place a bet? Which overclocks the mostest?

    Ok I'm a gambling man...I'll put money on the underdog.

    Curious since I have not over clocked my computer yet with the same 680i ASUS mb

    I say dead heat.

    FSB of the CPU should crap out well before either chipset hits it's limit, and that's only if the raw clock of the CPU doesn't reach it's max first (I suspect it well, unless it's a miracle chip that can do 4GHz+ on air).

    Looks like this is going to be easy: at the moment I can't get the 680i fsb over about 265MHz without a lockup, meaning that the overclock is limited below 2700MHz. I'm pretty certain it's the northbridge controller: dropping the multiplier makes no difference, and the RAM is actually working slower than it has in the past. Raising the voltage on the controller makes no difference, nor does lowering it. I've already mounded a 50mm fan to it to no avail. Still got a few more tricks to try, but it's not looking good for nVidia and their insanely hot northbridge.

    Have you ruled out an FSB hole?

    The P35 is a FSB beast so I had to place my bet there. Not that a 680i is too shabby either.

    I've tried several settings, but not a huge number. It appears to be a limit thing, not a range thing. But as I said, more playing to do now that I've worked out why the main (IP35) rig died (OCZ RAM karked it).

    I've heard of more P35 o/c success stories than 680i and 650i. Why is that? I guess you can't have the best of both worlds (OC CPU and SLI).
    680i solutions cost far more than P35's too.

    This saga gets weirder. After someone elsewhere said that the 1201 BIOS is probably the best overclocking one, I flashed back to that from 1302. 2700 worked a treat, but 2800 brought back all the same locking up problems. So I went back to 2700, which now wouldn't work any more. I had all the settings exactly as they had been twenty minutes before (I write everything down, remember) but no joy - so I'm back on 2600 again.

    Interestingly, the problem doesn't seem to occur in Safe Mode, suggesting a Windows issue. But what app etc doesn't like overclocking? More testing to be done methinks.

    Right, I may be back in business. Touch wood. I completely reset CMOS (jumper moved, battery out etc) and then tried again: 2.8GHz is now running at 1.40V, which did not run before. No time to play now as I have a curry night later, but I should get time later in the week.

    So which one turned out to be the better overclocker? For me the 680i was. I was able to hit 3.6GHz on the 680i and be stable but only 3.5 on the DFI DK P35.

    P35. I had to drop that back to 3100 to get 100% stability (3150 was about 99.99%), but I could never keep the 680i stable over 2700. The problem was the northbridge - it seems luck of the draw whether your NB is any good or not.

    I've now bought an B Grade P5K-E WiFi to replace the P5N32-E SLI.

    Probably the same on all mobo's regardless of the platform.

    680i failure rate seems much higher than most other boards. While anecdote isn't stats, I've had two boards: the first died, the second wouldn't overclock properly. If my four P35 boards, only one has died. It may or not be a coincidence that all defunct boards are Asus.
