Bad OC mobo?
 

I got an nf7-s rev2, 2 acutally, 1 with the new colorred dimm's and 1 with the old black colored banks but both don't seem to go much over 213 fsb Although I did most of my testing so far with the older nf7.

So far, I've tried
2 mobile 2400's of witch one can make 2500+ mhz on 1.7V bios, wich is the on e I used for testing mostly, the other one I haven't tested for max yet.
tried the mobile with and without socket l12 mod (166)
I've tried merlin's d25 rev3D cpc on bios and triests d24 vanilla bpl 3.19 both of wich didn't gave much over 225 stable fsb (all at multi 8)
no Vmods done but there's an actic cooling fan on the NB and a zalman passive on the SB
Also I'm using an OCZ DDR voltage booster at 3.3-3.4 (except 3.0 for the apacer sticks)
I've tried bh-5 sticks from corsair, kingston and muskin 2*512 and bh-5 mushkin 2*256, ocz el 4200 and eb 3700 2*512's and apacer 2*256

All to no avail.


I'm pretty much out of ideas as to what may be the problem.
If you guys know anything else I should try then please tell but if that's it, I guess I just got bad boards
The odd thing is the old nf7 was supposed to do 240 fsb out of the box...

*edit* In the mean while, i've tested numerous modded biosses from trats, triest, tictac and merlin, all yielding about the same fsb's:
225 windows stable
227 superpi run possible (not stable though, crashes sometimes)
231 memtest errorfree

Your title says it all ;).

not all motherboards are created equally :)

the only way you are going to get that bugger any higher is by voltmodding the board to increase the voltage to the NB, watch out though as 2v+ can kill the chip.

thx for the input

on to the next issue then :)
As I see it, there are 3 things I can do:

1 Sell the bad OC'ers and buy new nf7's untill I got a good one, loosing money (??€) for every board that isn't good enough.

2 Try to find a seccond hand good OC'ing nf7 with the risk of being scammed.

3 Buy a DFI Infinity or Lanparty, in dispite of the problems people have been having with these boards in the past, I hear their latest 2 bios revisions are quite fail safe.

Get a DFI I'd say ....

I have a DFI infinity, and with the latest BIOS it works excellent:)

Lol, that's settled rather quickly then :)

To the shop!!

haha, my last 3 mobo's havent gone above 202 on the fsb, and now with my new nf7-s rev2, i cant use odd multiplier settings....i cud get 2.5 at 1.65v with my mobile on my a7n8x-e at 12.5x200, my new nf7-s cant even do that, i get 12x200 tops, i tried 10x200, and tried raising it up to 208 and it crashed, 10x204 was barely stable

My NF7-S Rev2 will hit 220 but couldn't pass Prime; does everything else. 215 is Primestable. People here just keep RMA going until they get a good one. That's why Newegg is so goood.;)

when working with Mobile CPU you need to the L12 mod in order to be able to use all multipliers

Yeah I know! :grum:
But bloody Newegg doesn't' ship to BE and if I'd have to do it via a trustworthy American *cough* :p It would still take forever and increase the chance of getting caught at customs.

I started a thread about this on born2oc to find out if there were some shops like that in or around Belgium that do this aswell and if not, how people did it around here if they wanted good OC stuff but I got some dismissive comments about the idea of RMA'ing a perfectly good peace of hardware.


If that about the L12 mod was directed @ me: it says in my first post that I tried both with and without ;)



Nways, ontopic :p, apa @games.telenet advised me to test with 1 stick instead of 2 and it's going great: 250fsb seems to be the max memtest stable :feesten: with this stick in slot 3.
Typically me to overlook testing with 1 stick instead of 2 but even still, I would never have imagined it would yield a 20 fsb gain :o

it was directed at ssl6

l12 mod eh? hmmm.....y does that sound familiar....where can i get the info on how do it, maybe ill try with 1 stick of ram as well....i do have 2x512 afterall, cant hurt to use only 512

OH YEAH.....thats the pin mod i tried with my duron, lol, i knew that sounded familiar.....dunno y i never thought of that before though.....my mind jus blanks out for....long periods of time....sometimes....ok, more than sometimes

do you have a digicam with a good macro mode? Would be interesting to post the L12 mod in detail here if you decide to try it :)

macro mode? dunno what that is....but i do have a digicam, i can post some pics of the pin mod. the info i found said its different on bartons then thouroughbreds, i havent found anything for bartons yet

mobiles need the same l12 mod as the thoroughbred's but only the 166 fsb conversion will work, the 200 fsb conversion won't.

Here's the socket mod: http://www.geocities.com/trats102002/nf7sFsbsense.html
Just work in mirror view if you're going to do the pinmod on the cpu.

Or use this: http://www.ocinside.de/index_e.html , select what you have.want at the top and it 'll show you the correct connections to make.

I can take a pic if you want although I don't see the use since the guids already show you how it's done...

so i cant set my mobile to 200??? bummer
