ABIT AN7 Overclock bios READY - by Mr Enduracell

[tictac]

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

[r3b0rN]

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

[FlyingHamster]

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

[enduracell]

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
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 before I can OC or was that only for 133/200 FSB cpu's? I've got a 166 Barton myself soo...

[enduracell]

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

[tictac]

Very nice memory Bandwith score on Alpha3

congrats

[buff]

sooooo
how high FSB are u guys able to get?

whats new in the "R2" versions?

[tictac]

Dominos forget those Alpha 1 2 3 R2

coz the new Alpha 4 5 6 is online

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

15 Alpha4

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


lets..... Overclock

[tictac]

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

[tictac]

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



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

[tictac]

Alpha 4 5 & 6 need L12 mod to 200MHz

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

[tictac]

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

[r3b0rN]

impressive.

[Dominos]

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?

[Yitch]

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

[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

12/18 BIOS update as follows :

Change Log:

1 . Changed the Optimal and Aggressive CPU Interface Table above 200 MHz FSB:
- DISABLE CPU Interface has been modified to be more user-friendly
for high FSB overclocking
- ENABLE CPU Interface now recalls the lost bandwidth when FSB
is above 200 MHz and at a multiplier that is under 10
2 . No L12 Mod needed for 133MHz & 166MHz. All CPU will be running on 200MHz CPU Profile

FINISHED... that is Final Version for AN7

Cheers

If Pinczakko manage to create rom to disable COMMAND PER CLOCK

u can add it in on that bios later

ABIT NF7/NF7S Rev2.0 - Ultimate Memory Bandwith

latest feedback update from abit usa

I've tried the last bios and I have the same problems than with the others.

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.



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?
