250 FSB DC SYNCH and ABIT NF7-S

**Dagalidis** · 08-13-2003, 10:40 PM

Last night i moved back to d10 BIOS and droped down VDD to 1.75 Volt....
Now? 250 FSB 100% STable and still dont believe it.......
I want more but 1.0 has 250 as top limit FSB.....
Just Take a look.....

**Dagalidis** · 08-13-2003, 10:44 PM

But i like for 24/7 246 FSB whish give me MOOORRREEEE Performance.....

**Evil_Spork** · 08-14-2003, 01:53 AM

nice! i wish my mobo would do over 182fsb LOL.. thats why its getting RMA'd tomorow!

**Dagalidis** · 08-14-2003, 02:01 AM

Good luck.......
And just remember to try BIOS d10 (for Ver. 2 NF7) and see whow it goes......
You will find alot of Performance hidden right there.......

**Dagalidis** · 08-14-2003, 02:04 AM

Now my main target is to have 250 X 10 = 2500 MHZ stable 24/7....
Since now all are ok but 3D is not working well...
Probably need a litle more VDD juice like 1.80 to 1.85 to have 3D World back to action........
We will see...........

**Penti** · 08-14-2003, 02:21 AM

Thats verry nice. What timings are that in and are all things stable(like memtest86 and prime) at 250 except for 3dmark?

**xigfrid** · 08-14-2003, 02:23 AM

get a chip that can do more than 2.5Ghz , then you will have the 250*10

btw nice NF7-S, can you tell us what mods you did ? I mean Vdd mod, Vdimm mod, rads on mosfets, zalman32NB on southbridge , special cooling on northbridge ?

**Dagalidis** · 08-14-2003, 02:28 AM

For 250 FSB i set timmings at 11-3-2-2.5
For 246 FSB i set timmings at 11-3-2-2 and was stable.....

I also tested 11-3-3-2.5 to have stable 3D at 250 FSB but no luck until now....
I will raise VDD up to 1.8-1.85 and redo all Becnhes from begining...

The BIOS 1.0 goes from 245 FSB (246 measured with CPUID) directly to 250 without midle steps like 246 - 247- 248 - 249 and this was another problem.....
But since now all are running very stable and FFFFFAAAAAAST.......

**Dirty_Punk** · 08-14-2003, 02:34 AM

so you aren't at 250 100% stable.. if you aren't 3d stable you aren't stable at all
try 7-3-2-2.5 settigns, all the memory i have tested lower the max clock if i set 11

**saaya** · 08-14-2003, 02:35 AM

your using the 1.0 bios on the rev2.0 board???

**Dagalidis** · 08-14-2003, 02:36 AM

Before the downgrade from d18 to d10(for Ver. 2 NF7) BIOS i had VDD up to 1.95 for a stable 242 FSB...
Now with 1.0 BIOS i have VDD mode back to default voltge (1.75 Volt) measured with my digital multimeter.....
I dont use any other MODS (VDDR - VCORE e.tc.)
I have stock cooling on it but AS3 under Heatslink and Passive Cooling with a Simple heatsink on the other Bridge.....
Mosfets are not using extra Heatsinks.....

I guess i am VERY VERY LUCKY

**st0nedpenguin** · 08-14-2003, 02:37 AM

Holy poop!

Mine doesn't even like anything over 210Mhz, good going man!

Lets clear this .....
I am 100% stable at 250 FSB but with a multi set to 9.5 which give me 2375 MHZ which is not what i want........
When i set 250 FSB X 10 = 2500 MHZ then all running fine even Prime 95 - CPU TOAST - Fast PI - SUPER PI but 3D applications after a few minutes just closing .....

And seems to me needed a litle more VDD or a much effective cooling to the Chipset........

PS...... If any of you have same mobo Ver. 2.0 just try to Flash d10 (for Ver. 2 NF7) BIOS and findout what will happend.....

If this confirm my success then we must ask from ABIT to give us a new copy of this BIOS with SATA correction on it and leave all the other code back to original d10 (for Ver. 2 NF7) BIOS.......

Is a good IDEA.....

**saaya** · 08-14-2003, 02:57 AM

If any of you have same mobo Ver. 2.0 just try to Flash 1.0 BIOS and findout what will happend.....

it killed the board of a friend

well he needed a new bios chip that was all... i really wonder why your board is still working...

are you sure its the 1.0 bios? where did you get it? i heard of 2 other people already who tried to flash their 2.0 boards to 1.0 and they board wouldnt post after that...
please post a link, i wanna try that bios when i get my nf7-s 2.0 back.

**Dagalidis** · 08-14-2003, 03:06 AM

I always doing flashes with ABITs Flashmenu utility and is working perfectly.....
There is a note on ABIT homepage that is not able to reverse to any BIOS prior to d14 if i remember well but this is not true when you are using flashmenu utility.....

The most importand of all if before you make a flash ALWAYS you must be sure you are with 100 FSB and remove from memorie any aplication is running......

Since now i've made up to 20 - 25 FLASHES with this board and many many more times BIOS reconfiguration and until now thanks GOD all running well........

**Dirty_Punk** · 08-14-2003, 03:08 AM

some people use bios 10 with rev 2.0, because bios 10 give much more overclock VS bios 14-16-17-18, more bus & more performance, and there is no problem to go back to bios 10, use winflash

**saaya** · 08-14-2003, 03:19 AM

he did use winflash, he was on tha 16 bios before because i told him it works best for me. he used winflash to get the 10 bios flashed, all went fine, need reboot window popped up , but it never booted again.

i heard of some special commands to get back to 10. do you mean that? or did you just use a floppy with the 10 bios to boot and hit alt-F2?

try the L12 mod + bios 1.0 => nice combo for 230-240Mhz

**st0nedpenguin** · 08-14-2003, 03:29 AM

I have my 1800+ all ready to go, just waiting till I have the time to pop it in, prolly on saturday, unless I snap and stick it in tonight.

Here's hoping I have enough AS3 left!

**Dagalidis** · 08-14-2003, 03:34 AM

Please dont make me think i have the GOLDEN SAMPLE on my hands because i dont believe it.....
Abits flashmenu have all the options you need for a safe FLASH.....
I remember a day which flashing procedure just freeze in the middle of flashing and after a Ctrl - Alt - Delete combination i end task the flashmenu and restart again flashing.....
Even with this bad situation still working JUST FINE..... But NEVER i mean NEVER forgot to make boot at 100 FSB before do a FLASH Procedure....
So i think if you want to try you MUST be FLASH back to d10 (for Ver. 2 NF7) BIOS....
The risk of a Bad Flash always will be like ghost around us.......

**Dagalidis** · 08-14-2003, 04:10 AM

With 246 FSB and 10 multi all 3dMark 2001 & 2003 passed at default card speed...... 400/850 GPU MEM for my fx5900 by Leadtek..... But is not the higest scores i got because i dint try yet to push more....

I have a lot of tests to do before find the best FSB/MHZ combination for a 24/7 use.......
Here i post just the begining of a happy story and just wait to see the happy ending of it.....

Yes. Wanna see. My ram single sticks can easily do 243 2,0-11-2-2 at 3,17V but in dual channel... that's another story

At least with multi above 9,5...

**xgman** · 08-14-2003, 07:23 AM

Interesting thread. I never did inderstand why we had to sacrifice this performance when they updated the bios from 1.0. Please send this thread to Abit.

**althes** · 08-14-2003, 05:29 PM

That is very good. Get some good memory and you will ok to go.

**Kunaak** · 08-14-2003, 07:35 PM

how about some benchmarks finally

Super PI, Hexus Pifast, Sisoft sandra mem test, PCmark.
those I'd be interested in seeing
