NF7 with vdimm/vdd/vbt mod = Nice

[Mickey Padge]

After running with DFI for a while I thought I would give the NF7-S a go what with all these new mods popping up

I have done the Vdimm mod as shown in the motherboard faq article . I also did the vdd and vbt as shown by tictac here :http://www.xtremesystems.org/forums/...5&pagenumber=6

My voltages are 2.06v Vcore , 1.7v VDD/AGP and 3.3v Vdimm .

Running 240x11.5 more stable than I have ever had an NF7-S board

I am also using a mobile 2400+ with the L12 mod .

This score is with APIC off :http://service.futuremark.com/compare?2k1=7734977

With APIC on the score would be over 22000 easy But it just wont run at these speeds with APIC on

Before the vdd boost and vbt mod I was never stable over 225 fsb on the same board ( even with the vdimm mod I did first )

For some reason I cant go much higher because I have a board that likes 1.5v vdd for more fsb and that voltage wont be enough for the vbt on the ram . Sort of a catch 22 situation there

Tictac great work man I would like to know if the vbt mod could in any way be derived from the AGP voltage ? It would help alot if it could .

Keep up the good work guys . Its good to be back on the NF7-S scene instead of the DFI boards . I just love that I can power up my PC and it boots first time and everytime
Cheers

PS : This is the first time I can run a high fsb/vcore on the NF7-S

hmmmmmm.....


your m2400+ w/ Abit NF7 w/ 2.78ghz @ 240FSB w/ r9800XT 459/378

vs.

my m2400+ w/ DFI LP b/ 2.52ghz @ 252FSB w/ r9800pro 459/384


you get 21,799
i get 22,000 flat


hmmmmmmm.... i don't remember if I had APIC enabled or not.

Congrats Mickey Padge,

Your score would indeed be over 22k by how much who knows.

IamAnoobieCheez,

I would say you defo had APIC on, if you compare to my score (in sig) u should be able to determine why i say this

[Mickey Padge]

Heres my DFI score with APIC on :http://service.futuremark.com/compare?2k1=7592940

APIC off :http://service.futuremark.com/compare?2k1=7592912

I cant get to 245 stable with my NF7-S due to the vdd issue .

I used the same drivers etc.. for the tests .
Its good to be able hit these speeds with the Abit board as I have not previously been able to do so .

It seems from these results that people stating the DFI board was weak in 3D just does not hold true

Anyone else want to throw in some 3Dmark2K scores for a compare ?

Links would be nice

Cheers

EDIT : I think my 9800XT was clocked higher in the DFI results TBH . I cant remember what though . I have had a few beers tonight so cut me some slack

[Mickey Padge]

Thanks mongoled

I will continue to use my Abit board I think . I love to mod boards like this and then see clear results for your efforts

No more cold boot issues for me

Also this is the best result I have had with my mobile chip in terms of the highest CPU clock .

I wish I could r404 gas my vapo . I might get some more mhz if I could

[mongoled]

U know sommet guys, can u imagine the scores we would be gettings if we could 3d bench at 280mhz



The more i think abt the more im inclined to think that these XP chips could really be awesome. Not that their bad right now, but if we could hit 280mhz, just like some P4 systems im sure that these chips would give the P4's a good bit of competition!

Just a few thoughts

mong

[Mickey Padge]

The term " $hit off a shovel" springs to mind

They would be fast to say the least .

T'is but a dream though..........

"Sigh"

[tictac]

Congrats Mickey Padge..... :thumbsup:

kinda shock over here... coz suddenly u pop out with NF7-S result instead of DFI LPB Result ....

Welcome Back to the Dark side... .... powerfull u become...

[Endre]

So, much more fun to squeeze those MHz's out og the NF7 than to just set the FSB right up with the DFI, right? 8)

Ok will try my best to make the vbt = V-AGP

need help also......
do anyone here know which is AGP Mosfet on this NF7 series board....

cheers

[Mickey Padge]

Thanks for the replies guys

Its true that there is a certain element of fun from the modding process . I missed the modding side of things with the DFI board and got annoyed when the Vcore mod would freeze my board under load

It is much more satisfying modding a board and reaping the rewards of your time and efforts . The DFI is a great board , but what with the Vcore mod not working , the low sata write speeds and the worst of all ...... cold boot issues ......

I thought it seemed like a good time to test out my NF7-S with a few of the mods that were popping up . My board had potential before , I could tell . The prime failures I was seeing seemed to be related to the boards NB and ram . The mods I did simply ironed out those instabilities .

I did the Vdimm mod first , but it gained me NOTHING in fsb results . Which was a bit of a shock to say the least . When I added the vdd booster and then raised the VBT/VTT by linking it to VDD eveything seemed to come together , which was nice

My board does not like high vdd over 240 fsb for some reason thats why I am hoping to link Vbt/Vtt to AGP voltage

Keep up the good work guys

Thanks to Tictac for helping dig out these mods and making the BIOS to hang it all together

Cheers

[tictac]

ok no problem....

i'm sure this board capable of 250+ FSB stable

its just a matter of time & luck....

[Mickey Padge]

I just ran Super Pi 1MB test and got 36 seconds

The best I could ever get out of my DFI with a 24/7 stable rig was 37 seconds

[tictac]

wow.... 36sec...... :thumbsup:

r404 gas to go mickey... hehehe

[Mickey Padge]

Hehe ....

Yeah anyone in or around the London area know of a place to get a vapochill PE r404 re-gassed ?

I am sure I could get more out of this CPU , as it will post at 3000 mhz , but nothing more

I think I will let my board settle in at this speed for a while . Then try and squeeze a few more drops out of it

Anyone else have any 3DMark2K compares ? DFI or ABIT ( or any NF2 board for that matter )

Cheers

check my sig...

[Mickey Padge]

Nice scores

My modest stock cooled OC on my 9800XT is slowing me down for sure . I just have not had the balls to mod it yet ( if ever ). I can replace a motherboard if I screw up a mod , but a 9800XT is a tad expensive

Also I modded my 9700pro before and was underwhelmed with the results I had .

Are mods for the 9800XT easy ? How are they in comparison to the 9700pro mods ?

Thanks guys

At what speed? The lowest CPU frequency I've got 36s at is 235x11,5.
2-2-2-5 timings...

What about you?

[tictac]

here a quote from bachus_anonym

... that little Dual-Mosfet that i take vtt measurements at gets REALLY HOT... i need to figure out how to cool it down... so far i have a fan blowing on it & memory slots...

that Dual N-Channel mosfet getting really hot after the vbt mod

here is the pic of dual n channel mosfet....(circle with yellow)

Mickey Padge ... hope u cool down this mosfet properly before it fry out.....

[Mickey Padge]

Hmm . Lots of dead motherboards from this mod .............

I wonder why my board is fine ? Not a single hiccup .

I will check that mofset when I get back from work . I have checked the temp of the ram and noticed no increase in temps there at all . Just a bit warm like normal .

I will test out a few different voltage settings too , just to see what results I get as I have not really tested any other settings yet .

I was just pleased to hit 240x11.5 stable

[tictac]

the dead board they have diff mod than urs

they do Vdimm = V i/o mod

while u have another diff mod Vdimm mod from motherboardfaqs.com

i think there is something happening after the Vdimm=V i/o mod combine with Vtt=Vdd mod

still trying to figure it out... :/

[tictac]

Mickey Padge ... i just check back my voltage reading after vdd=Vbt mod

if u have Vdd @ 1.7V
The voltage will flow to the dimm slot @ 1.7V also(no decrease voltage)

so if u have Vdimm @ 3.3V.... hope u can reduce the Vdd voltage to 1.65V only.....

Sorry Tictac I am not sure what you are trying to tell me here

It is interesting that everyone else did the direct hook up mod for the vdimm . I was never tempted to do it that way . It always looked a bit risky to me .

Cheers

[tictac]

Mickey Padge ....

Automatic Vtt/Vbt is always half of vdimm voltage without any adjustment needed anymore...
