ABIT AN7 Overclock bios READY - by Mr Enduracell

Special thanks to Mr Enduracell from Abit USA Forums..He send me Modded ROMSIP for this AN7 board...i only help put them in & he beta test all this bios

All this bios POST FINE... and it is SAFE to flash with

15 Alpha1
- used normal ROMSIP bug fix
http://home.doramail.com/tictac/Alpha1.zip

15 Alpha2
- use Asus A7n8x romsip moddedwith bug fix
http://home.doramail.com/tictac/Alpha2.zip

15 Alpha 3
- use Alpha2 but with tweak the 200MHz table with 12-18 from DFI
http://home.doramail.com/tictac/Alpha3.zip

*Take note this bios Work Best with CPU with 166MHz default FSB

is this some sort of an attempt at making the an7 a good overclocker?? :D

does it add those extra ram timings that the dfi boards have? wut are the major differences?

Congratulations Tictac, this mod is a high class ones. I didn’t do anything. I just modded the SIP they u told me, but the really trick was to repack it. This only could be found out and done by u off course :D
I just have to make clear that the XP-Ms &3200+ may have issues on this BIOS. The L12 mod on this CPU give default 200FSB and not 166. The original BIOS from Abit doesn’t allow high FSBs on 133, neither 200FSB CPUs. So it only works for 166 default CPUs. Ôhe only way I figured out to go high with XP-M is to put an 166FSB CPU on, set CPUinterface enable and something like 10x233 for example, the save&exit. Renter the BIOS and save ur profile. Then switch CPUs and to make it work load the 166CPU profile. Save&exit. From now on u can oc without limitation. Take notice that it only need to reload profile only if u clear CMOS. I’ve done the trick with a ×P-M L12 modded but it should work without L12 too. (@least try).
The trick seems to have some side effect on mem errors, but I m not sure cause my profile is from first betas that had a freezing prob so I don’t know if any code get mixed up.
If anyone find another solution or know how main bin must be change please post.
The best unbaff band seems to give it the A3 one, but do ur testing too.

no... a better overclocker ;)

enduracell: Do I have do some special :banana: :banana: :banana: :banana: before I can OC or was that only for 133/200 FSB cpu's? I've got a 166 Barton myself soo...

No if u have a 166 Barton the only thing u have to do is just the flashing ;)

Very nice memory Bandwith score on Alpha3

congrats :toast:

sooooo
how high FSB are u guys able to get?

AN7 ONLY!!!

Special thanks to Mr Enduracell for romsip idea...
Now AN7 Bios equip with DFI Infinity ROMSIP table...

ROMSIP Table of DFI Infinity 12-18 Bios

all this bios has been beta test by Mr Eduracell himself. And all this bios post fine
Now It work best with 166MHz & 200MHz Default FSB CPU

http://downloads.modlabs.net/bios/beta/Alpha6.zip


lets..... Overclock

will add in 12-31 , 1-21 & 1-31 ROMSIP
later :D

so far enduracell manage to hit 233MHz CPU Interface enable
with his 512 MB (Double side) BH5 stick

http://downloads.modlabs.net/bios/beta/an7.jpg

i wonder how high will this an7 board hit with single side 2 x 256 MB rams :D

Alpha 4 5 & 6 need L12 mod to 200MHz

for 133 & 166MHz CPU to overclock higher than 200MHz stable

Here is latest result

with 2 stick of 256 MB BH5 rams

Max Vdimm in Bios (3.2V)

Athlon Mobile

240MHz x 11 = 2.64GHz

Super PI 1M = 37Sec

NOW I see AN7 Overclocked

impressive.

So only 200FSB default is OC'ing well with alpha 4-5-6? Anyways it looks good ;) How high did he manage to get with Abits original BIOS? And 240 is Dual channel right?

Someone finally figured out this flakey motherboard! Congrats tictac and Enduracell!

this is with 2x256 BH5 (3.2 from BIOS) mobo out of the box w/o a single heatsink on it or a mod :)
All gredits should go to tictac off course :D

My specs:

- AN7 Rev 1.0
- XP-M 2400 IQYHA L12 modded
- 2x256 Buffalo DDR466 (Micron Chips) CAS 3 DC
- Club3D Radeon 9700

Windows will start at 247FSB apparently running OK.

http://www.iespana.es/xtro/fsbr6.png

Using clockgen I can push it to 260mhz FSB (not bad ;)) This is with Dual Channel and CPU Interface ON.

Problem is I'm having memory errors whatever FSB I put, doesn't matter if it is 166, 200 or 250.

I have to say that my memory is rated CAS 3, but even with AN7 1.5 official bios it doesn't work OK at 3-3-3-11, if I leave it running at 2,5-2-2-11 it will work at 207FSB flawlessly.

So maybe problems are caused by my RAM?

TICTAC PM !!!!

sorry i too lazy to check em... :(

Errr thanks for your help then :stick:

ok... :)

AN7 OVERCLOCKED!!!!!!!

Athlon Mobile... no L12 mod

wow nice figures :D argh! tobad I'm not at home ATM, I'll be up all night trying to get this puppy to run fast :D

ATTENTION
Disable the CPU disconnect function and always use 6/6 otherwise may experiences random freezes
Tictac the 133CPU propably work ok with C18R2 I will tell for sure tomorow so don't bother looking at it:)
S2K don't work anyway from BIOS ;)

yeap out of the box only with ur BIOS :toast: :banana:

I noticed a funny bug :D I cant boot with 166FSB or 200FSB, BUT 220 and 230 works fine? used clockgen upto 245, at 250 the comp. died due to voltage issues :d It needs over 1.9 in bios to be stable over 2.5 and I only gave it 1.87 from bios at 10x250 :D
But I have a little problem, some boots it works fine but others it freezes quick. I have the divider fixed at 6/6 and CPU disconnect funktion - disable. I'l try some more and report back later...

EDIT: Now this BIOS is really weird!?!?! I can only boot at some specific FSB's and I get random freezes all the time, superpi and 3d are fine up to 240 but only for a little while :( I hope you pin down the last bugs so that it'll run stable couse this is a major asswhoping bios!

even though the FSB is much easier clock up... but the bios need furture tweak & patch... 250FSB in no time :)

yeah .....i received many issue on this new bios especially,.... system freezing & tons of erros in MemTest #5

Hope some1 can continue R&D this bios...

kinda busy lately with my study... dont have much time to look into it again for time being... :(

Good luck bro.. :beers:

Should I go for a NF7 or AN7 then after reading this?

Also what is the best bios for both?

DFI Infinity is a top class board why would you need another board?

Here's my highest "benchable FSB" with AN7 and AXP-M (no L12 mod), CPU Interface Enable, 11-2-2-CL2, N24AAC18 bios :

http://img19.imageshack.us/img19/739..._245_pi1mb.jpg

henry check out Abit USA forums

Mr Enduracell just post new bios for AN7

Might fix the bug... especially the freezing issue and memtest #5 issue

anyway... Congrats... 36Sec PI on 245MHz FSB :)

Thanks tictac, i'll give it a try :)

I have a little problem with N24AAC18 : the max vcore i can use is 2v only, it can't load windows with > 2v vcore.

Btw, do you think L12 still needed for AXP-M / 133 FSB tbred/barton ?

this problem exists on my combo too. I can't use Vcore above 2.03v and enter WIndows. But this bug exists on official BIOS too. I think it must be ACPI related.

Try use ACPI from other board..

maybe throw in DFI ACPI or NF7 ACPI in to that bios could help

or disable APIC mode... but that will hurt Benchmark score back down :(

Ok I wiil through DFI ACPI and see what happens.
THanks for the advice tictac :D

AN7 vs DFI Infinity
clock per clock benchmark result

check it here:
http://www.overclockerindo.com/modul...a3d516889da434

so they're both very simular ? I cant speak the language its wrote in either :(

similar clock per clock Performance

but

DFI can clock higher than 245MHz... up to 265MHz stable

but AN7 maxed out @ 245MHz stable :D

whats the most stable board out of the AN7 / Infinity / NF7?

Why not use the ACPI from NF7? DFI has problem with 2v+ too, but I have never heard about a NF7 having problems...

And the most stable between those three would be NF7 or AN7 IMO, and since AN7's bios is f*cked up I'd go for a NF7 if I wanted stability....

Hello tictac,
help me for the agpvmod please...:stick: ;) :)...thanx .

Hey! Welcome me, I just got the AN7. Which BIOS up there do you guys recommend me using. BTW, the files hosted by TicTac don't work! Looks like he took off the file.

check his website and you might fid them there ;)

It's BIOS "NAAC18" and "NAA131" that are any good. From what I have seen, the first one goes throu the roof FSB wise but some have freezing problems, including myself. And the second one is better than the org. bios from Abit but not as good as the first modded one and has as of yet not had any freezing problems ;) My suggestion is that you try both and see which one that works better ;)

Freezing problems when you overclock or even on stock too? If so, I think I'll go the NAA131, because although it might not have crazy FSB, it won't freeze on me too.

EDIT:

For some reason, my Kingston 3200 Value Ram won't do 2 - 2 - 2 - 11 @ ~195mhz but will do 2 - 2- 3 - 11. The thing is, not even a voltage increase will allow it to go up to 2 - 2- 2 - 11. So at stock 2.65volts, if I increase upto 3.2volts on memory, that won't work to. But I know it ain't the ram, it's the motherboard, because sometimes it actually boots up, but most of the time it doesn't.:mad: Is there a fix I could apply? BTW I just got the board, so everything is stock, so that means BIOS is stock.

I have only seen BH chips, some samsung and a few CH-5's + OCZ new EB do ras to cas 2 (the one you cant run as a 2) Some chips do it when they are underclocked but not all, and when I say underclocked I mean like PC2700@PC2100. You'll just have to live with it. I cant run 2-2-2-11 either but it's fine upto 230+ with 11-3-2-2 so why bother? :D

Hehe really :(

O well.

It is though, value ram, so I'm quite impressed when its aimed at running at 8-3-3-3 @ 200mhz.

BTW, would you have a copy of the 131 BIOS? Because tictac's link ain't working for me.

Care to rehost those files again? I tried finding them all over the net, and I can't find any, well any that I find, the links don't work.

I tried the NAAC18, boots lovely at 240 but, even at 200fsb or 166fsb, the BIOS freezes my comp at desktop upon startup.
I wanna see how the 131 bios is like. Tah

This is the best BIOS for the AN7 right now. http://forum.abit-usa.com/attachment.php?postid=342587

Thx there mate! Will give it a shot, but damn, the 1T CPC sounds pretty tight lol, I don't think my ram can handle that, it's only Value ram lol, but damn!

Thats the only BIOS that doesnt freeze in memtest(for me anyway) and allows 230+ FSB stable speeds. Im running 9.5x237.

Thx twiggy!
Still I'm quite curious to how high my Kingston Value 3200 ram can go up to 1T command rate.

You know there's an extra file in there, is that a component of the BIOS too?

So do I type something along the lines as:

AWDFLASH 15dE8bPL.BIN /15dE8bPL.md5

??

which bios is the best? :D

Hello peoples,
Selamat siang tictac, :)

Because there are always dead links to that nice moded BIOS-files, i would like to put this files to my webspace and add a link in the uppest posting. Can anyone send me all important/good BIOS-files of Abit An7? Then i upload it to my webspace and post the links here, so that an admin can post this links to the upest posting too. Please send me all BIOSES you like to see here.

tictac: Are these BIOSES the most important? Should i upload it to my webspace then?

lol... i already upload it on modlabs server

is there any other bios left over?

But 2 links (one for backup purpose) are better, right?

However, if you need my help i can offer you webspace for that BIOSes. And beside that, you are doing great work, tictac! ;)

Hmm.. I suppose this thread is dead as a doornail by now... but thought I'd just ask...

any plans on releasing any new AN7 modded Bioses... even if you don't I just wanted to say thx to Eduracell and TicTac... cuz without you guys my OC never would have worked... thx so much! :clap:
