Moblie Athlon, am I missing something?????

[Gazzol]

Hi all, first post so be gentle with me

Put my newly aquired Mobile Atlon (2500) stepping IQYHA in my NF7 and I can't get it stable at all, also it seems to run very hot (idle temp 38c 1.65V on water)
Also it posts with the wrong voltage, 1.575V, I understand it should be 1.4V ish as standard. All cacheing is dissabled in the bios as is cpu interface. Ive tried timings as slack as 11,6,6,3 for the memory. I've done the pencil volt mod for the chipset and tried just about every modded bios there is 1T & 2T and nothing can make it stable above 1.8Ghz. I'm comletely BRASSED OFF, with carriage it cost me the best part of £70 and it's slower than my Barton which I was happy with. I only bought this cos I heard how good they were and that they were doing 2.5-2.6 Ghz on air and mine won't do 2Ghz on water :confused: :confused: :confused:

Any sugestions

Thanx

[sabrewolf732]

it is supposed to post with the wrong voltage. Socket A boards are not supposed to support mobiles so they give them the wrong voltage. idk about your other problems though, sorry.

Woah!

Where to start? where to start?

There are answers to everything you have posted and a lot of them are "newbie" problems (no offence)

1. Mobile chips have different pin arrangements for voltage, so your mobo recognises the default voltage wrong, just use the bios to manually set it.

2. 133fsb chips do not clock to high fsbs on NF-7s without a 200fsb wire-mod (use the search function or google)

As for your temp issues, can't help too much there other than asking you provide us with more details for your cooling.

the answers to all your problems are on this site, just try the search function, if you need anything clearing up, just ask.

Welcome to the sickness btw!

[Nubius]

Whoa...very strange indeed. I have an IQYHA 35 2400+ XP-M running 2.5GHz for every day use at 1.85vcore, can do 2.7GHz but uses more vcore than I care to put in it, and this is on air cooling. You shouldn't have needed to do any volt mods to it at all. Also I noticed my NF7-S v2 board put the Vcore at 1.55 even though (in my case the stock is 1.35) your stock vcore should only be 1.45


CPU Interface BTW needs to be enabled especially for overclocking.

http://www.pc-tweaker.ch/Downloads/Bios/Modded/Abit.php

Go there and try this BIOS: Abit NF7-Sv2 D26 CPC-OFF mantarays-xt

What exact kind of memory are you using BTW? Because nothing should need those loose of timings

EDIT: 2. 133fsb chips do not clock to high fsbs on NF-7s without a 200fsb wire-mod (use the search function or google) Not true, I can hit 235MHz-240MHz (DDR470-480) quite easily on this board with my mobile and I'm limited to that because of having 1gb. At the forums I mod I know a couple people with mobiles and NF7's that have 2x256 that hit 250MHz (500FSB) rather easily. This without even a chipset voltage mod also.

So have you never tried the 200fsb wire mod? You are lucky to hit that kind of fsb with a mobile chip with out a wire mod. The only mobos that can get an XP-m to high fsbs without a wire mod were the DFI NF2s

[Nubius]

well since we're showing images :D

http://www.27thavenue.com/images/cpuzshot.jpg

I could never get mine to hit up at 2.8GHz though, nice indeed.

I've also never done any mods to this board. No chipset, no wire mod, nothin.

EDIT: I'm air cooled BTW, probably why I can't reach 2.8GHz

DOUBLE EDIT: BTW Mines with 1gb of RAM also, 24/7 use. I can run 235MHz, but I noticed in some games, it'd freeze for like...2 seconds and loop whatever sound was playing, then snap back to normal, at 230 this problem doesn't occur

[STEvil]

no L12 on mine either, 225 fsb with 1gb 24/7... 250+ with 2x256.

Check your waterblock mounting job and a kinked hose maybe.

[GazC]

are you guys running the tictac bios with the modded romsip?

that is the only way around it afaik.

[Nubius]

Yeah I'm using the one I suggested to the dude. Abit NF7-Sv2 D26 CPC-OFF mantarays-xt

Of course with stock BIOS this crap would be impossible. Of course TicTacs has the soft L12 Mod but that puts it at 166 not 200

I get 220 on my mobile and an7, no wire mod.

[GazC]

I get 220 on my mobile and an7, no wire mod.

But can you not go higher? What ram are you using?

[STEvil]

Tictac D27 right now, was on stock Abit bios before and all that tictacs changed was higher performance.

[sabrewolf732]

But can you not go higher? What ram are you using?

Yea, most an7s crap out at 220-225. Doesnt really matter what proc or ram. I am using bh5.

[Nubius]

That TicTac D27 didn't work for me at all. Didn't even like going above 220FSB...the D26 however will let me go up to 245, however with a bunch of windows instabilities. 235-240 with windows stability, but not game stable. and 230 game stable, of course I haven't bothered trying like , 231, 232 etc...etc... to find the absolute last spot it'd be game stable.

Ever since I lowered my AGP Aperture to 128mb from 256mb games no longer crash at 230 like they would even at 210 beforehand. :D

[-Acid-]

I,m on a AN7 stock and can go faster still on the fsb my mem craps out at 223 and i,m using the stock bios.

nubius mate i could get to 2715 on air but needed a delta to do it.
i,m using water as i hated the fan noise, running faster is a bonus wait till my twin cooling tower,mb mods are ready then i have 3122 stable :woot: :woot:

[Nubius]

nubius mate i could get to 2715 on air but needed a delta to do it. Yeah I am using an SLK-900A with an 80mm vantec tornado. Looking to piece together a watercooling kit in a few weeks. I just did 200x13.5 for 2.7GHz even, but it took like 1.975 Vcore to get it, too much voltage for my likings especially for 24/7 use. 2.5GHz with 1.85 is my sweet spot.

Idk cuz on my albatron and the same memory I did like 235 iirc. Also my freind crapped out at 222 on his an7. I just think an7s dont go that high.

[Gazzol]

UPDATE:- have now got it stable, the problem was I was trying too high fsb. It's been prime stable for 9hrs+ but at 166fsb *13.5, 166fsb sucks but at least its stable @2.2Ghz.

Will just have to keep burning in an tryin higher fsb a bit at a time.

Cheers

Mine came out of the box hitting 200x9 =/ I would think yours should too

Hmm seems that after doing a bit of reading up, Tic-Tacs D26 soft L12 bios is the one I should be using. I'll give it a go an see how we get on.

What type of memory you running on?
Is it sync with FSb speed 1:1?
The board does not support Athlon Mobile... so whatever default Voltage , FSB & Multiplier .... you have to manually set them... :toast:

so maybe you do have to do a wire mod. Or maybe you dont have 400fsb support on your nf2. Is it an older nf2??? If so update the bios.

Yea, On a mobile I have never had to use a wire mod. However on a tbred 1700+ i had to use a wiremod to break 210. Also I couldnt boot with a 10 multi on that 1700 hwoever the wiremod made me boot at 10. :banana:

[dippyskoodlez]

But can you not go higher? What ram are you using?

As did I... NB pooped out past 222fsb... tictacs bios did not help at all. This cpu had done 267fsb on my infinity. :cool:

Don't take it so much to heart dude. I understand what you're saying and I've seen that required in many cases, but this doesn't seem to be the case with any newer boards as of late. Everyone I know who has a mobile and nforce2 board have never had to do the wire mod including myself and have been able to hit 230MHz+ FSB.

TicTacs Soft L12Mod making it 166 seems to do quite the trick. I got the 200FSB wire mod right here:

http://www.geocities.com/trats102002/nf7sFsbsense.html

What chipset cooling were you using on the NF7? I got my NF-7 from 219fsb to 231fsb by replacing the stock chipset cooler with a Vantec Icebeq and AS Ceramique.

Then when I did the chipset and Vdimm mods it could hit 233.

We both had (I still have for a couple more days) an abit an7. I had a NB1 on mine. All an7's I have seen crap out at 220-225fsb.

[Gazzol]

Update:- Now got it stable @210*12 but am usin 1.95V :eek: . Will continue burning in and see if I can do any better, either faster or stay the same an lower the volts. I must say however that I'm a bit dissapointed with the V's required to make this chip stable, my old Barton 2500 would do 2.5 Ghz an I had it @ 230*11 but it needed 2.0V so as things stand I spent nearly £70 inc carriage to run 0.5V lower, I'd have been better off buying a better water block (Maze 4 at the mo) an usin the Barton

Maybe you are just unlucky with your XP-m. But did you do the L12 mod (166/200FSb)?
http://www.logan.eclipse.co.uk/images/NF7%20166fsb.gif
From http://www.logan.eclipse.co.uk/abit_nf7_(s)_v2_0.htm For 166Mhz fsb.
Did make a great difference for me first I couldn't get it above 230mhz fsb, now the amx I've reached is 263Mhz fsb (suicide) and 250 Pifast stable:

Evil - That's nice man considering you have dual channel 1gb!

I might just have to do that mod when I get a WC setup see if it lets me have a higher FSB shot....

but my games like to crash at higher FSB's :(

EDIT: I have an L12 mod site right here, but it shows the pin going into diff holes than the one you posted...I also have that site marked too actually.

Which one is true!?!

[Gazzol]

EvilWhiteDragon not done wire mod yet am about to try, but, which is best 166 or 200, the one you show above is for 166 or does it not matter?

[eR1k]

Doesn't make that big a difference imo :)

[Gazzol]

Okey dokey I'm gonna give it a go, I'm gonna do it on the pcb side usin conductive paint.

[Tony420]

Usually the L12 mod is only needed for FSB's higher than 240-250 and definatly needed for 2x512 setups

also...the L12 mod has NOTHING to do with CPU frequency...only FSB

[mluckey]

I just wanted to chime in here for a second.

I have had five NF7-S v2.0, all with mobile xp-2400+, and not a one of them is modded, nor uses anything other than stock BIOS. The slowest runs 2 x 512MB RAM in dual channel at 2-2-2-11 at 221 x 11, with 3:3 ratio, interface enabled. The fastest 223 MHz FSB with the rest being the same. The L12 mod did nothing on any of my boards. It seems that was an early NF7 trick, and no longer applies (at least to Mobiles). I never needed any tweaking, other than voltage for anything under 210 MHz FSB even with Dual Channel 1 GB. I found that I could get even generic RAM to run up to around 210-212 MHz FSB with enough juice.

[Kelldor]

Hi folks! I'm not an NF-7 owner, but I've had some bad luck and some good luck with wire tricking my GigaByte + 2400 mobile (IQYHA). My 1st try ever I used the War Mod (http://www.dfi-street.com/forum/showpost.php?p=395&postcount=30) without the L12 mod and it worked great til I tried changing my multies (dip switch on main board). I did permanent damage and lost almost half of my multipliers. I tried again later with L12 and noticed increased stability, otherwise though I don't need L12 cause I can adjust my FSB in bios no prob, but with it I notice I'm alot more stable. Other than losing half of my multipliers, my system rocks now! I'm very happy with it, and will take it further once I get a better HSF. ATM I'm using just a 1.7v wire trick mod from the Interactive Pin Mod Guide ( http://www.ocinside.de/index_e.html), but switching back to the single wire war mod soon. This is what I'm doing atm with a stock AMD cooler:
http://tinypic.com/2iqh3m
(Ignore Speedfan temps in pic, MBM5 temps in systray though).

Gazzol, I wouldn't be too concerned about the high voltage required as long as your temps are good. Seeing what several of the other folks here have accomplished makes me believe these cpu's can really take alot of punishment.

Question for those hitting 2.8-3ghz: Was a VDD mod required to get that high? Very curiouse what your VDD voltage is at at those speeds, thx :)

[-Acid-]

This thread is really starting to pick up keep them comming

[Tony420]

Heres my dad's computer. No mods on the board yet...(no l12 yet either). This is 24h prime stable already but im running it again for another 24h before I try 230 @ 2.9v(1T). I left some room on the screen so you can see my kittie's :toast: :banana: :banana:

[Nubius]

http://www.27thavenue.com/images/cpuzshot.jpg

Timings not quite as good as tony's :D I believe I have tested them at 2-2-2-5-1T at 220MHz before though. Was Sandra benchable, but I didn't do any insane tests nor keep it there for very long.

No mods here that's 2T with 2.9v

I always recommend doing a L12 mod in hardware!

It helped me a lot... software (bios) mods were not enough.
G'luck!

Same here, back when i was running 2X256mb xms3200c2 the wire mod got me over 227fsb to 242fsb on my NF7-S. It wasn't stable but i did get 235fsb stable for 24/7 use. Not bad for an unmodded mobo. :)

Hi timko thats a nice fsb but surly with a few more volts (1.9v) you could run a higher multi like 11 or 12 maybe

[SAE]

Hmm, timko, my problems were starting at 238MHz :D

Doing the L12 wire mod got me to 260+ (even to 273)... BIOS mods are no perfect substitute.

[mluckey]

This is a good reference thread, and it is kinda showing a pattern already.

On the Abit site a while back a similar thread statarted, and got similar responses. The results were that 2 x 256MB RAM reached about 5-10 MHz higher than 2 x 512MB RAM. The limits for non-modded boards were about the same as those for L12 Modded boards (with Mobiles Bartons on newer boards). Modded BIOS got higher FSB than non-modded, but always at the expense of a RAM performance hit of 10-15MHZ to make up. Some made it up, most didn't.

The average Joe with 2 x 512MB RAM could easily hit 210 MHz FSB without a hitch with any quality RAM. A well-tweaked, stock everything board would hit around 220-228 MHz depending on cooling and voltages. With hardware mods and creativity, much more can happen.

I am not seeing anything different than on the Abit site. The Aquamark, and ORB scores also bear this out, Most all of the boards (L12 modded or not) fall in the same region.

[Discipuli]

i have a mobile athlon running @ 2.2 ghz right now on air, it can reach a stable 2.4/2.5GHZ easily at 1.67-1.7 vcore with my cooling, but the performance gains don't outweigh the extra heat and loss of CPU life from all the extra voltage .
No desktop mobo fully supports the athlon XP mobile , try flashing your BIOS to a newer version .

Yeah 238Mhz is pretty much the max for my board at the mo. No amount of vdimm, vcore, vdd increase or ram timings relaxation allow anything stable above 238. If I had soldering skills then I'd be doing all the available mods but sadly I'm not so I have to make do with it for now.

However, I will be installing my new waterkit soon so hopefully I can stretch the multiplier a little bit :)

Mate, the L12 mod does not involve soldering at all. :)

You only have to take out the cpu and put a lil U-shaped thin wire (from an old floppy cable or such) into the right holes. That's it :up:

Perhaps this is too little, too late, as most have abandoned the NF2 platform . . . but here's the recipe for high fsb on NF7-S:

One bone stock NF7-S
One D26 MantaRay XT (CPC on) BIOS
One L12 hardmod (one wire)
One APIC-disabled OS

Ram (all 2x512):
Mushkin LevelII R2.0 (non-BP PCB), Memtest clean to 250, 2.5-3-3-6
Ballistix PC3200/4000, Memtest clean to 242, 2.5-2-2-5
Corsair XMS3500, Memtest clean to 235, 2-2-2-5

I've tried five boards, all bone stock with OEM NB sink. All run 3D stable with 2x512 at 1T, up to 248, as long as the ram is Memtest clean. By '3D stable' I mean all four Marks, Aquamark, and 30' of the IL-2 and SS2nd Encounter demo. The boards also pass PCMark2004 Pro (all tests) and pretty much everything else I can throw at it.

I had to test the boards in the span of a week and did not want to experiment so I did the L12 hardmod and APIC-disabled OS to eliminate those variables. I decided to use the latest modded BIOS available so I picked the D26 MantaRay (I think an APIC enabled OS will work fine with this BIOS). One of the boards above was actually an RMAed piece from Abit!

This BIOS has the AGP latency timings slacked to 255 to enhance 3D performance, and needless to say, it works. Highest buffered I got is 3853 at 248, 2.5-3-3-6. CPC is definitely on as I get 500 higher points in 3DMark2001 versus the D26 CPC off BIOS.

I've tried a sh_tload of modded BIOSs previously, and none of the NF7-Ss could bench 3D above 222 or so (2x512, 1T), even though they were 2D stable (and probably Prime stable) to 245. That D26 MantaRay Xt BIOS by TicTac is the charm :banana3:.

The CPU I used for testing is an AQHYA (or whatever) 2600-M at 2600-2645 mhz (37 sec SuperPI 1M @ 2645). Cooling is a HC200.

[Clevor]

What I found is all the boards max out around 218-222 on good ram with stock BIOS. You can boot high fsb and bench 3D if CPC is off with the stock BIOS (not sure this was the case with all boards).

The L12 mod allows the ram to run Memtest clean higher, however, the boards would still not boot above 225 with CPC on. The modded BIOSs allow you to boot high fsb with CPC on, however none were 3D stable above 222 or so. The D26 MantaRay XT finally allowed me to bench 3D fully stable at high fsb.

As I settle for nothing less than 3D stable/2x512/CPC on, the D26 BIOS was a Godsend. I also happened to luck out on some early Mushkin LevelII R2.0 recently which does well on the NF7-S, which allowed me to foray into the 250 fsb territory.

[Waxman]

We both had (I still have for a couple more days) an abit an7. I had a NB1 on mine. All an7's I have seen crap out at 220-225fsb.

Believe it or not, I had an AN7 that did 260 :D

Tictac moded bios an7de8

Stock nb cooler and a SLK 900a

Mobile 2500 (IQYHA) @ 2600 mhz with ocz bh5 (still have them - 277 benchable on NF4)

The first one was a really crappy board - maxed out @ 225 (it had a plastic retention lever ;) )

The second one was really good - maxed out @ 260 (metal retention lever ;))

But that was almost a year ago, so I have no screenies of it

Sorry for that

[onemorekornkid]

I guess I might as well add my achievements.

I have the L12 mod and it allows me to boot at 260 fsb (stable? no), but that's only with a 1.7 vdd.

Right now I have:
218x11.5=2500 mhrz with 2 volts with a thermaltake extreme volcano 12+ (sounds like an airplane). Temps are nice, 104*F idle and 116*F load.
Value VX 2-2-2-11 (1 gig, dual channel)
6800 GT 460/1200 (1.4 volts)

I wish I could get 228x11, but my NB just can't take it. it couldn't even do it with one stick in, forget about dual channel. I would volt up my NB like you guys have probably already done but A: I don't have anything besides the stock cooling and B: I don't have a multimeter.

So yeah, i happy with the performace I have now.

[Clevor]

I have one board modded with the VDD pencil mod, VDIMM mod, VCORE mod, and huge sinks and fans on the NB and a smaller one on the SB, fans blowing on the mosfets, and it overclocked the worse! I undid the pencil mod and finds it runs Ballistix the best this way.

On some boards the VDD works (helps), but on Ballistix they run best at 1.4. More VDD seems to help with BH-5. Amazingly, all boards bench 3D fine at minimum 1.5 VAGP; I might need 1.6 to get by 3DMark2003 on occasion.

[austinbmxnig]

i just recently got rid of my desktop 3200+ and a7n8x-e deluxe for a nf7-s rev.2.0 and a 2600mobile...........right now im burning in at 250x10 @1.825 volts, i'll be back with more later.........

my sig is wrong BTW...i switched to the cpc-on bios as thats not what was limiting me.........i want to hit 2.6 eventually

[onemorekornkid]

^ can you give me a link to the that bios please?

[Gazzol]

i have a mobile athlon running @ 2.2 ghz right now on air, it can reach a stable 2.4/2.5GHZ easily at 1.67-1.7 vcore with my cooling, but the performance gains don't outweigh the extra heat and loss of CPU life from all the extra voltage .
No desktop mobo fully supports the athlon XP mobile , try flashing your BIOS to a newer version .


THATS WHAT I'M TALKIN ABOUT 2.4/2.5 @ 1.7V :stick: Dude you make me sick LOL :p: :p: :p: Lucky you.

Update After doin L12 mod (sort of (connected pins on back of mobo usin conductive paint)) a lot of burnin in, and a lot of messin in bios (Manta Rays D26 XT) atm, am now at 2.4 Ghz :toast: (220*11) but at 1.9Vs :eek: can go to 2.5Ghz :banana: :banana: :banana: (220*11.5) but needs 2.1V :eek: :eek: :eek: :eek: and even then not prime stable but can play games an benchies. 32C idle with DD Maze 4 an about 42C flat out after a few hours. Have ordered 226W Tec but not sure If I should have bothered.

Any ways thats where its at, better but still sucks. Will keep you posted of improvements keep em comin.

^seems like yours is identical to mine.

I bought mine after hearing how good they were, found out what was supposed to be the best stepping (reputedly) an then shopped arround till I found a store that had em. My barton 2500 which is now in the drawer was about the same as this so I just hope it gets better with a few more miles on the clock.

gazzol

[onemorekornkid]

The A steppings are not only power hungry, but don't usually get over 2.5 ghrz

[Clevor]

I think the best were the early ones: 0349-0359 (or whatever weeks in a year), particularly the MPMWs, all IHQYAs (think I got that right).

It also simply depends on the chip. I have one 2600-M that does 2600 @ 1.68 VCORE, another that requires 1.85. I have six, including two 0346MPMWs I got from Newegg when the Mobiles first arrived on the scene, but I have only tested two so far (not those).

One reason I stocked up on so many is these 2600-Ms are just the ticket for dual CPU boards like the Iwill MPX. These boards are collector's items, and I am fortunate to have two of them. A minor mod is needed to get the Mobiles to work, and of course, they overclock great! There's also an adapter on the market that gets them to work on these boards.

[scrible88]

IQYHA's were the best steppings in my opinion. I really liked my AXP system @ 2645mhz. It really seemed a little bit quicker than my A64 system @ 2600mhz 24/7. Of course my A64 benchmarks better, etc but I kinda miss my AXP!

[Clevor]

That 37 sec SuperPI 1M time I got on a Mobile at 2645 mhz on an NF7-S is pretty darn decent. What's running in my Intel rig right now is a 3.0C at 258 fsb or 3.87 gig. It too knocks off the same time. But consider it's an 800 fsb Northwood. The Mobiles on a dated NF2 platform are more comparable to the old 400-533 fsb Northwoods, e.g., 'A' of 'B' CPUs. No way those buggers will come close to 37 sec.

Since my NF7-Ss are performing so well at high fsb, I ended up keeping four out of five boards. I was gonna keep just two. I'd only get $23 for them used here in Japan anyway, so not worth dumping them. Maybe I'll put one in my grandma's rig with a Mobile at 2650 mhz :p:.

not about xtreme overclocking :P

Ok, I've just done the L12 mod with the wire :)

http://www.baddass.pwp.blueyonder.co.uk/images/l12mod.gif

^^^^ The red one ^^^^

I still can't seem to go any higher in memtest test #5 without getting errors. Again, I have tried increasing the vdimm and vcore and slackened off my Patriot XBLK timings right off but still to no affect. I've even done the same with 2 x 512Mb OCZ 3200 EL Rev.2 as well but again this is no go :(

Is this because my BIOS (D26 Manta Rays XT CPC On) already provides the L12 in software and as such is, perhaps, clashing with the wire mod in some way?

Should I revert to a BIOS that does NOT have software L12?

[SAE]

Hmm. For me the software mod (bios) and the hardware were working great together... maybe it's your memory sticks?

Sometimes one stick is worse than the other one... and it starts erroring like hell increasing clocks passing a certain point. You may also need some serious burn in ;)

Could be your cpu does not like the fsb... I once had a 2400+ mobile not liking anything over 238/240...

I've never tried the MantaRay BIOS without the hardmod! I only had a week to screen five boards so I wanted to be sure this wasn't an issue. So no, I don't think the hardmod + MantaRay BIOs is the problem.

I only used the red loop; four boards defaulted to 166 at Optimized Defaults, the real early 2003 board defaulted to 200. What did you get?

Try switching positions of the sticks; I found the boards real consistent in this. I pretty much knew my shiny spreader XMS3500 always worked best in the #1 slot on all the boards.

Try playing with the VDD; some ram like 1.4 best, but it depends on the board.

[Gazzol]

Ok chaps here's the latest:
Am currently running @ 2.5Gig, 10.5x240 (1.9V) upto now I've done the following: 166 wire mod (wired for 200 but still posted 166???), pencil V mod for chipset (+ 0.2V) and the 3.3V Vdimm mod. As you can see this is a huge improvement over what I could achieve at my first post, this is all down to you guys and the stickys etc in this forum.
As things stand I cant get my rig to go any higher than this even though I now know it can do more. If I increase fsb or multi I can get it to post with an increase in V's, it starts to load windows but then freezes at the boot screen, the fact that It posts etc means its close. Whats the next step guys??
Am usin Black MantaRays D26 1T. CPU interface on (tried off), fsb spread spectum is off (tried on + off).
Any Ideas

[-Acid-]

my board seams to cap out at 223 fsb no matter what volts i put through the mem or the northbridge i can do 223 at any multi up to 14 (not enought volts to get to 15 eek 2.3v plus)

I,m thinking it might be my psu what are you lot using to power your X-xp rigs
I got a (dont laughand i know its really a 350, 550 is peak rating dammed PR tricks) Qtech 550 which i modded shorter 12v power lines (less restance) bigger heat sinks (p4 heatsinks) it runs stable and the rails are great but i,m thinking the 16amps on the 12vline are hurting my oc

If it pauses interminably at the Welcome screen at 235-ish and above, you need to run an APIC disabled OS.

Best way to do this is set the BIOS to APIC disabled first, then reinstall WinXP. I always keep an APIC-disabled DriveImage handy for this occasion.

You will note when I tested my five boards, I ran an APIC-disabled OS as I didn't want this to be a factor. However on one board, I accidentally booted into XP OK when the BIOS was set to ON, so it may depend on the board.

The Epox 8RDA3+, Rev. 3.2 runs same high fsb as the best of my NF7-Ss, and can do it on a regular APIC on OS. Looking over my notes the other week, I saw a 21,450 3DMark2001 score with Ballistix, which is at least as good or better than anything I seen on my NF7-Ss.

[onemorekornkid]

TRy loosening the 1t timing, it's an impossiblity for me to be stable at any setting at 1t

[Clevor]

TRy loosening the 1t timing, it's an impossiblity for me to be stable at any setting at 1t

The D26 MantaRay XT BIOS (CPC on), goes a long way in helping this :). At least in benching 3D at high fsb. Some say only certain boards can boot high fsb period.

The usual scenario is:

1. Memtest clean at high fsb but won't boot Windows
2. Memtest clean at high fsb and 2D stable but won't bench 3D
3. Memtest clean at high fsb and 3D stable (try the Manta Ray BIOS)

As I mentioned earlier, with the stock BIOS I could boot Windows at high fsb and bench 3D at 2T. At 1T, won't even post above 225 or so. The modded BIOSs takes care of that. Doing the L12 is a minimum though.

If your ram is not Memtest clean, don't bother booting.

It's kinda a moot point as I get better 3DMark2001 scores at 222, 2-2-2-5 than 236, 2.5-2-2-5 and 248, 2.5-3-3-8. 2x512s at 1T. Similar with 3DMark2000 while 3DMark2003/2005 are heavily video card dependent.

I gained over 1000 points in 3DMark2001 with a Mobile Barton over an XP at same clock, due to double the L2, particularly at 2-2-2-5.

[Zilla]

I hear the D27 BIOS improves HD performance as it has newer Sil BIOS, so I'm curious whether you guys have tried some of the modded BIOSes based on D27 and which one seems to be the best performer... ;)

[[timko]]

I've tried some of the modded D27 BIOSes and found that some weren't 3D stable at the same settings compared to what I had prevously done on Mantarays D26 XT. Needless to say I flashed back to D26 and my NF7-s chugs away nicely at 238Mhz FSB :)

I don't post over here very often but I just saw a link to this thread so I thought I'd jump in.
I have an AN7 see (Sig) that runs Prime95 (12hrs) stable and 3DMark2001 stable with a 2600-M Proc at 10x245 or 11.5x229 all the time using Enduracell/tictac 17de81ts BIOS and 2x256MB PQI Turbo TCCD PC3200. I recently decommisioned a DFI NFII Ultra B that ran 10x258 with the same combination CPU and RAM using Hellfire_BIOS_N24LD619-3EG-Rev3. Neither had the L-12 mod. The AN7 runs at 1.825 Vcore and the DFI was at 1.95 both on air with Zalman CNPS 7000 hs/fans. In addition my Soyo KT600 Rev 1 runs a 2600-M at 12x200 no L-12 mod with 1.57Vcore since the board doesn't support voltage adjustments.
