Abid NF7-s Overclocking Issues

Hello all, I just swapped out a Shuttle AN35N pro motherboard for a Abit NF7-s. The reason I had to do this was the shuttle board had an EXTREEMLY fast system clock, and it was casuing some major bugs in programs I rely on.

Anyways, on the shuttle board, I have been running an Athlon XP 2400+ M (15x133 / 2Ghz @ 1.45V) overclocked to 11.5x200 @ 1.7V with no problems for over a year. Considering everyone raves at how the NF7-s is the best AthlonXP board I thought I would have zero problem carrying these settings over.

Well, got everything set up to my liking at default speed just to be safe, and then played around with overclocking. At 10.0x200 @ 1.7V, it wouldn't boot! If I wanted a 200MHz clock, I had to go all the way down to 8.0x200 @ 1.7V. Unreal . . .

I know we all hear that getting a good XP Mobile chip is a bit of a crapshoot, but I know this chip is good. Is there anything I might be overlooking that you can think of offhand?

Oh, and hopefully not a stupid question, what does the "cpu interface" option do in the bios?

EDIT : IMPORTANT EDIT, does this motherboard have a huge bias for temperatures? I'm getting idle temps of around 46-50 degrees C at stock . . . which seems high.
 
are you running you ram 1:1, or however the NF7 expresses memory ratios? NOT by SPD, very much not 5/6 or 6:7 or anythign else.

what bios version are you running?

have you tried givig your chipset a little extra voltage?

the CPU feed on my old NF7-s was a bit low, so have you tried taking your Vcore any higher?

as for the CPU interface............i THINK that it just allows the mobo to fudge the FSB a little, to keep it in exact synch with the ram clock, however if anyone knows better, please enlighten us all.
 
Hrmm . . . ok, no SPD, I have something else to expirement with.

I have the ratio hard set at 1:1 (which is for some reasly expressed as 3/3) but for timings I had it default to SPD. I *THINK* this is doing what I intend it to do (200MHz double pumped @ 2-3-3-6), but maybe not . . . is that SPD option doing something else I am not aware of?

Haven't given the chipset any extra voltage, will try that, but from what I see using ABit's motherboard monitor -- all the rails are slightly overvolted as is.
 
since you are running an nforce 2 board, you might want to try timings 2-3-3-11.

various theories as to why it is so good for use on the NF2, but i lean towards it having an optimal ratio of first try memory hits : latency.

it's somthing to try, at least.............
 
Just to shed some insight on the cpu interface option. I don't know exactly what it does but when I had it disabled i couldnt post past 200mhz FSB. I enabled it and I'm running at 11x227. Vcore of 1.65. Ohh and my temperatures for the board are about 24C and CPU at 38C..... just for comparison. Like they said, try different RAM timings, I've got mine at 3-3-3-11.

edit: I've got a xp-2500 M
 
Turned on that elusive "CPU Interface" option.

Computer has been running a Prime95 torture test for 30 mins now at 10x200 @ 1.45V. Maybe this CPU is better then I initialy though . . .

Of course, I have a new problem to deal with, which from the search looks like it is going to require its own thread :(
 
CPU interface overclocks everything a little bit with my understanding.

With it off I lose nearly 1000mb/s in Sandra.....LEAVE IT ON!!!
