Overclocking a XP-M- help please

i used to have one stick of kingston pc3500 bh5 and that stuff wouldnt go above 207fsb on 1T timings. mine simply does not like double sided.

i now run 3*256 and it operates as duel channel :D

i love my barton, i played about with it some more today due to this thread. i was at 227*11 (desktop xp2500, KQYHA, possibly the best stepping).

i used to need 1.775 vcore and it would idle at 39* (on air!)

i have taken it down to 220*11 and i now only need 1.7vcore (in bios) 1.66vcore in mbm5 (woot!)

that is an xp2500 doing 220*11 on standard volts, prime stable with a max of 44* hit.

i am going to keep this setup for ages, its the roxx
 
XP-M's are more than capable of getting past the 3Ghz mark with the right cooling (check out the linky in Weescott's sig ;) ) The DFI ultra B's were capable of insanely high FSB's (I'm sure Marci mentioned in the region of 270, but that required a whole world of modding and even going as far as actively cooling the Mosfets to stop if self destructing :eek: )

I have always found that the 2x256 clocked better than 2x512 (never used 3x as needed the other slot for the Booster!) Don't know whether that's just because I only tried a few sets, but the 'popular wisdom' was that the 2x256's were better - just as the 2x512's were better than the 2x1Gb's in the beginning I guess!

Anyway - back on topic - Let us know how those Mushkins fair on the board - and which bios you decide to go with - just don't be tempted by the ones that allow you to mess about with Command per Clock (1T/2T) - really slow things down at 2T! Another vote for the MantaRay bioses here, can be found HERE

get the tictac bios m8 i use that on my dfi nf2 board and am running 2.7ghz @ 270x10 @1.7v and its @ full load 24/7 as i use it for my home server

I can't let this go by without saying something at least.
1:Tic-Tac wrote 4 bios's for the LPB, none of which will get you to 270fsb.
2:If any socket A cpu got to 2.7ghz on 1.7v myself and a load of other peep's would have spent days queing for it, with no food and water if we had to.
3:Perhaps Norris you could provide us with the link to your Toaster sig over at DFI street? :rolleyes:

Oh yes nearly forgot, here's mine. Link
 
how did you get your NF2 to run happily with that ram?

ive got the twinmos version of that ram and it doesnt run nicely at all. will a booster make a lot of difference?

i am glad someone agrees with me

just been overclocking mine a little best i could get was 245fsb 2 2 2 11 cpc on this is with 2x256 mushkin specials with bh6 probly need a booster to get 250 stable as bh6 likes lots of volts, sandra mem test was 3760/3294

my cpu sucks and tops out at 2400mhz even then its abit iffy carnt expect much for a 3yr old chip and the fact that my psu totaly sucks 12v rail is at 11.3 and fluctuates all over

Is that in an NF7s v2 or a DFI DaZzZa? If it's an LPB or Infinity then 3.3vdimm should see you nicely to 250fsb and a bit beyond.
 
its the ultra infin, my psu is very badly undervolting everything so i think that is holding me well back, think i might order a hiper type r 580w sometime in the next fortnight

Going by the look of those graphs i'm amazed you've got as far as you have :eek: It looks more like there's a couple of dying batteries powering it, not a psu :D A nice new Hiper should soon whip it into shape :D

Make sure AGP is set at 66 or 67 and not auto

set Vcore to 1.7v and try 200x12, every XP-M I've had has managed this no problem (had 4)

to the guy who had 2.7ghz with 1.7 volt:
LMFAO

My Best Stable:
202x14 2.83ghz @ 2.05v on water
220x12 2.64ghz @ 1.85v on air

and that was regarded as a very good chip :p

btw check here to see what others get:

Was your question for me Matt82?
Click to expand...

yup, shoulda said. your ocz vx is the same at my twinmos aa4t stuff, but on my NF7 it doesnt clock at all (they say UTT chips dont work well with nf2 etc)


will the booster make a lot of difference for me?

Yes i would have thought it would. I don't know if you would loose dual channel though. On the NF7 i think the n/b voltage only goes up to 1.8v, if that's the case then it will limit how far you can push the fsb. VX by the way is utt ch5, which does clock well on the NF2 but like old school bh5 does need and like lots of vdimm.
 
mostly been said, but a few things i would suggest:

- Get a good modded bios, running D27 TicTac myself at the mo which seems good. Was on D26 Black Mantary from TicTac before that. Def worth looking into these
- L12 mod will help slacken the Northbridge timings off and hopefully allow a better FSB overclock. Only bother with the 133 > 166 mod as detailed here

- Set the BIOS settings as detailed on same link. can help a little
- slacken mem timings to start, maybe down to 11-4-4-2.5, but aim to tighten up to 11-2-2-2 eventually
- find your FSB limit first and then push multi later. board should be good for about 235-240 max
- some boards have a glitch where setting the vChip (NB) at 1.4v actually volts it at about 1.8 - 1.9v. some people find even better stability at a 1.4v setting because of this, than at 1.7v ("max" in BIOS)
- dont bother with CPC off BIOS's, takes too much of a hit to be worth it

will suppose this will work on a dfi infin board too badass?

Yes it does. The advantage of using it in a DFI Nf2 is that when booting to optimized default you start off on the second set of rom tables, not the first. which means as you set up saving and exiting, you only register and jump one set of tables not two. Much less chance of bios corruption when your looking for a high fsb.
 
just tryed that wire trick and it didnt work, failed to get to post screen even after i took the bios battery out to reset the bios :( this is with a tbred is it different between tb-barton-xpm?

was no signal on my monitor
