A lot people are running at 200+. I cannot do it for now but I know my mb (8rda+ rev 1, a7n7x-dlx rev 1) cannot handle it. Bought a nf7-s specifically for the purpose of cracking 200fsb.

the question is how high do you want to go?

be sure that you up grade your bios as soon as you get the board.

i couldn't get above 166 with my mobile chip until i did.

also, you'll need to do a vdd mod to your board + vdimm + vtt mod to get your board above 220 mhz fsb...

good stuff though after you've done all of it... or else, your best bet is to go with the dfi infinity (can run high fsb's w/o any mods).

I already am in the process of getting the DFI Infinity from a fellow here who says it will do 250 FSB. So that's not my issue, my issue is that I have seen almost no one talking about OCing the Mobiles actually doing it with FSB raised above 200, usually its something like 12.5x200. Now what's the point of that? It makes more sense to pull more FSB and less multiplier for performance.

I just want to make sure it's not an issue with the CPU itself that you have to physically mod it to get above 200 FSB. I distinctly recall some article online saying you have to do an L12 mod for that to happen.

This is why:

Most people, myself included, only have PC3200 RAM. Most motherboards top out at under 220FSB, so there's not much headroom anyway. It makes overclocking much simpler as it eliminates your memory/chipset from the equation.

i have a mobile 2500+ that i ran at 10 x 250 mhz fsb

so... it's possible...

as for the L12 mod... that was with the non-mobile bartons.

you won't need the L12 mod for the dfi infinity.

most mobo's do stop at 220ish...

except for the dfi board... and the nf7-s but only with tons of vmods...

I'm just getting the system together: 2400+ mobile 35 watt and NF7-S. SLK900 with quiet fan. I should be able to take it to 216 Mhz, right?

Since I don't already have memory - can you confirm for my ignorint a$$: 216x2=433Mhz so I should be getting PC 3500 ram?

yes.

should be no problem at all.

 

[3LEMENT0]

AXP-M 2600
NF7-S
1Gig OCZ 3200
Thermaltake Tornado 12 HSF (lapped)
Only floppy drive installed

No HDD

Mem timing right now is at 2.5-3-3-11 at 2.7v
Running at 210 * 11 at 1.725v

running memtest for now to check for memory errors. Will bump up speed if I find no errors with memory and not hanging.

Will install OS on the weekend

Hope to reach 2.5 or 2.6 stable. If not 2.3-2.4 stable is good for me

It takes a vmod to hit 220fsb on an nf7-s? That's disappointing. Is that why the rig in your signature is only running at 207fsb? What can I expect from mine? It's a rev-2 obviously, and just over a month old. I would need PC3500 memory to do it properly, but if it would work I would be willing to buy better memory. :beer:

 

[HGC]

I just upped my FSB from 200 to 216 after reading the recent posts. Three hours of Prime95 with no problems. VCore still at 1.65, temps unchanged, all going great.

 

[trexpesto]

Now you'll get a little more of yer moneys worth out of th nice memory! How long were you running it at 200?

Anyone: when they say PC3500 is 433Mhz - is that rounded up or down or? So running 217 or 216 be more "accurate" 1:1?
As if it matters. EDIT: I'm sure it DON'T, I am just geeking out. EDIT: that's "geeking out loud"

 

[JeffCY]

Hmm, does this matter? I didn't know there was some sort of rounding issue. I currently have my FSB set at 217 in the BIOS, however the BIOS seems to display it as 216. Should I set it to 216 for more accurate 1:1? Is higher not necessarily better?

 

[HGC]

I'd been at 200 FSB for a few weeks. This my first overclock and I am a nervous virgin

I'm curious about the rounding issue, also.

I Have Your SAME board .... read this post!!!

I don't have the vdd mod done for my board yet.

well actually... it's done but it was shorted somewhere and caused my vdd voltage to be zero so i had to remove it.

i'll redo it again soon.

so far i can only get to 225 mhz w/o the vdd mod.

i am currently running 13.5 x 214

the vdd voltage seems to really effect the performance of this mobo.

once i get the mod done and get my vdd voltage past 1.7 (i'll try 1.85 or so) i'll push it past 230 mhz.

 

[3LEMENT0]

Running now it at 210 x 12 = 2520MHz running mem test and leaving it till later probably.

AXP-M 2600+
NF7-S
1Gig OCZ 3200 Perf

 

[henan]

Mobo: Gigabyte GA-7N400 Pro2 REv 2.0
Chipset: dual channel nforce 2
Bios revision: FE
Processor: 45 watt 2500 M
RAM: Adata DDR500
Timings: 6-3-3-2.5
FSB: 200
Mulitplier: 11
Voltage: 1.70
resulting OC: 2.315 ghtz
Cooling: Aerocool DP-102
Full load temp: 53 C

Sidenotes:
Video card: Radeon 9600 NP, OCed to 455 mhz core and 328 mhz memory. (VGA silencer)

My mobo totally sucks! Got it for the good features, had no idea the voltages were that bad... 2.7 max Vdimm, +10% vcore. Can't get the ram past ~450. Anyone know any good vmods? Also, my board reads the temps too high i think.

Working on a liquid cooling, see where that will get me...

 

[pelikan]

Good water cooling will probably only get you 50-100 MHz more with the same vcore. The real benefit of water cooling is the ability to use as much voltage as you want without overheating.

 

[henan]

Too bad i can't get higher voltage on my cpu.. I've looked all over for a vmod, but no one seems to use this board. Should get a nf7-s, just can't spend that money right now.

 

[OCedHrt]

XP-M 2600+ currently at 2233(203x11@1.55v)
Prime stable for about 8 hours, didn't go any longer.
Idle at 42C with Thermaltake ALX800 (not quite sure what the model is haha and too tired to look for the box) w/ a high speed Panaflo fan. Was idle 37C when it was cooler

Previously running at 2030(203x10@1.45v)

Maximum boot into windows speed is 2537.5(203x12.5) @ 1.75 or 1.8 not sure. I did not prime test this.

Still cannot hit 2600+ @ any voltage :/

But now that 35W ones are out..I want to "upgrade" again

Volt mods to the NF2 chipset were only needed on version 1.2. (pencil trick)
They were needed to stablize 3D apps past 205 on mine.

You cant buy a new NF7-S without it being version 2.0 now, so, no volt mods needed.

The only volt mods for the version 2.0 are for memory.

 

[3LEMENT0]

ok have a lot of time to tweak the system today and tomorrow:

NF7-S v2
AXP-M 2600+
TT Volcano 12
OCZ 3200 mem

running at 12 * 211 (2532MHz) at vcore 1.75v mem voltage 2.7v chipset is 1.7 or a notch higher.

Running stable but when I put all fans (5 fans controlled by the nexus thing) including the HSF fan to low the system hangs up. clearly heat issue....From 45/30 cpu/system temp it will jump to 54/35. Will have to test with lowest possible temp that will run without any hiccup....

 

[Jigglelicious]

Either my chip sucks, or there is something wrong, but here are my details and results:

Athlon 2400+ mobile
Shuttle AN35N Ultra
1GB OCZ PC3200
Radeon 9800Pro
Ethermax Whisper 350W PSU

With this config, the max I can reach is 2.2GHz @ 1.725V, and its not even stable at that! Prime95 crashes anywhere between 30 min and 2 hours, although its perfectly 'game stable'. So either my chip is just really bad, or there is a problem somewhere else - i'm guessing either PSU or motherboard. I've had this PSU in my previous system, and although I never overclocked, it was 100% stable. I'm leaning towards the motherboard, since it makes these really high pitched whining sounds when CPU activity is high, which i've narrowed down to be coil whine.

I guess 2.2GHz for $77 is still a good deal. But with all the stories of people reaching 2.4GHz with ease, i'm a bit disappointed.

Overclocking is not guaranteed

Your chip most likely needs more voltage. If you dont want to give it more voltage, reduce your FSB or drop a multi.

Your chip is fine. You have a bad overclock.

you are incorrect.

the vdd mod is still needed for the rev 2.0 for this board.

if you disagree, then go visit xtremesystems.org and see if anyone running over 230 mhz fsb on the nf7-s doesn't have a vdd mod.
