    Question Abit NF7-S v2.0 temps higher than GA-7VAXP with same components

    Hi guys,
    I've recently switched motherboards from GA-7VAXP Rev1.1 to Abit NF7-S v2.0. I switched everything over and its all working fine. Moved it up to 13x166 (which I was running on the GA-7VAXP @ 38C idle). Its running closer to 50C idle at this speed. I noticed on installing my SLK-800 that the clip didn't seem to hold it as firmly in place as it did on my 7VAXP so I thought this might explain part of the temp change. The other was that maybe its using the internal diode for temps and the VAXP wasn't. Other than that it seems ok. Went for 200x10 and it booted ok and temps didn't quite get up to 52C idle. I haven't had time to test with Sandra burn in and prime and the likes but when installing Medal of honor it crashed and rebooted.

    So I put 2.8v through the 512mb OCZ EL-DDR memory and set it to SPD settings rather than more aggressive memory settings. It crashed again but didn't reboot. I think the next step is to put a little bit more voltage through the CPU, I got up to 1.65v from the standard 1.6v but still crashed. Now with the temps creeping up to 52C idle I'm thinking I might have to get a faster heatsink fan, although I don't really want to have a noiser system since all the fans at the moment run at 2000rpm or slower.... Nice and quiet...

    Anyway I thought I would just see what more experienced overclockers make of this and what recommendations for faster but quiet 80mm heatsink fans any of you might have....

    Thanks.

    I been tinkering on my second system this morning, so I might as well show you.
    My SLK-800(A) has a thermaltake 80x80x25 3K RPM fan on it. It's just a tad louder than the case fans, but the whir is low pitched unlike 60mm screamers. When the case side is on, I can't even hear it. Also, make sure the heatsink is seated well. You could have a 200CFM 120v AC fan blowing on it, and if you're not making good contact with the core you won't have efficient cooling. I'll attatch a pic, so you can see the temps.

    I know Marvt74 has the same motherboard, and also has a similar problem.

    He is using my old Volcano 9 heatsink (which clipped securely onto the plastic hooks on my old GA7VTXE's socket).

    I think his heatsink on his NF7S actually wobbles from side to side when he touches it

    I'm sure he will be along soon with some feedback (oh no, he's on holiday in Spain this week )

    Mybe the clip spring lost some strength. See if they will mail you another one (Either the manufacturer or the place you got it).

    Well I ran it last night at 11.5x200.
    2100+ @ 11.5x200 1.725v
    Ran, warm booted, completed Sandra benchies.
    Seemed to be hinting at stability. But a cold boot doesn't
    start it up. 10x200 completed 3dmark2001 with 15050 (10 more than my KT400 board )
    But I'm really keen to get 11.5x200 stable as Sandra was reporting a PR of ~3400...

    Guess more volts are required?
    The power supply is a dual fan Enermax 350w supply running everything listed in the "My computers specifications" link to the "Arris" pc in my sig.
    Possible that I'm pushing it a bit much?
    Or just the cpu core isn't worthy of the speed I'm trying to get out of it? AIUHB 303?...
