Yeah really....:D


TicTac: will this permanently disable CPC? Is there a way to unpatch? ;)

[uwackme]

Ticcy... it is OFFICIAL, yes that does it... the CH5's work, Ill switch to BH5 and see now.

Nice job bunky....

Now... if you can do a version with 4247 Satabios in it, and also a version of the ASUS A7N8Xdeluxe Uber1007 bios with CPC off and 4247 you will TRULY be a GOD!!!!

[tictac]

The CPC Patch Work.... !!!!!!!!!!

way to go then ....

KEEP IT OVERCLOCKED

Special thanks to Mr. Pinczakko for helping us disable CPC option

[Rolle2k]

Just a question for you tictac.. i dont use my NF7-s 2.0 anymore, but maybe i build a second computer later so, i have a question.. is there any option in the bios to disable/enable CPC, or is it always off in this bios?
anyway great stuff for AN-/NF7 owners.

[blinky]

wait why would you want CPC off, doesnt it give a hug performance boost?

[saaya]

compability in dual channel? dont know

[Rolle2k]

CPC off is for Higher OC with dualsided RAMs, that means 512MB modules (some 256MB modules also).

[Dominos]

KHX have DS too

this is great :D It's the one in the link above right? Cant wait to try this one out :D

[Rolle2k]

Yeah, its this link for the AN7 - http://downloads.modlabs.net/bios/beta/N24AAC18-R2-CPC.zip

But for some people disabling CPC gives a huge performance lost, so in some cases it wont be wort setting CPC off.. but iv'e seen some people not loose to much performance and could up the FSB about 30MHz more, and thats really good. but the best thing is if it works with CPC on.

[MightyOne]

That patch just changes the binary, right? Cause I always flash my BIOS with FlashMenu - as I don't have a floppy hooked up to this rig anymore ...

edit:
Oh sorry, didn't notice that one of the links leads to the BIOS already.

[LilGator]

CBROM if anyone needs it, i'll test this with the D23 3D-Fire BIOS :) http://www.biosmods.com/download/award/cbrom207.zip

EDIT:

Once you run CBROM it output:

ORIGINAL.TMP 42KB
BIOS.ROM 1KB

So i'm guessing it just modified my original nf7d_23.bin file ?

[WildKard]

Lots of dual sided ram wont go high CPC

I use OCZ 3700 GOLD(2x256 rev1), and with CPC off I can do 255fsb 11-2-2-2-2.0 CPC enabled = 205 11-2-2-2-2.0 or 233 11-3-3-3-2.5 max clocks

Other people using 512mb sticks usually get worse results than that!

Good to see Abit users now have the freedom that DFI provides!

[jfr0]

This would be nice for those people who have locked chips. Higher fsb means more action on the core.

[LilGator]

Is all HyperX dual-sided ?

[uwackme]

Well, it still needs something. It may be ME, my boards never liked the later bios's, they like D10. I really need a D10 with CPC mod to know if it does the job. I got higher than I had, but the general flakeyness I get with non-D10 still is there, clouding my ability to give a definitive result.

In the meantime, my BH5's are cooking nicely, one set is at 240Mhz, the other 245Mhz now....memtest#5 11,2,2,2,cas2.0,e,e,f,dis on DFI LPuB. Thats a 35Mhz increase in error-free and 3Dstability point.... amazing.

[bachus_anonym]

so i gave some testing to this new BIOS from TicTac and Pinczakko!
in few words - WORTH TRYING!!! not a huge gain, but gave me 5Mhz on FSB extra comparing to d23_3D Fire...

i tested two kits of Mushkin LvL II - 2x256 and 2x512.
memory sticks in DIMMS 2 and 3,
CMOS cleared after each flash,
zero apps in tray and WinXP services reduced to absolute minimum,
benches run in same order for each BIOS and mem config: Sandra, 3DMark2001 and PiFast2.41,

here's some results:

D23_3d Fire - 2x512MB

240x11
--- Boot OK
--- Sandra OK 96%/91% 3695/3491
--- 3DM FAIL
--- PiFast FAIL

230x11
--- 3DM FAIL

227x11
--- 3DM OK 13808
--- PiFast OK 55.84s

D24_R3_ED_CPC - 2x512MB

240x11
--- Boot OK
--- Sandra OK 96%/91% 3700/3503
--- 3DM FAIL
--- PiFast OK 52.56s :banana:

233x11
--- 3DM FAIL

232x11
--- 3DM OK 14005 :banana:
--- PiFast OK 54.18

230x11
--- 3DM OK 13952


D23_3d Fire - 2x256MB

240x11
--- Sandra OK 96%/90% 3690/3481
--- 3DM OK 14121
--- PiFast OK 53.01s

D24_R3_ED_CPC - 2x256MB

240x11
--- Sandra OK 96%/90% 3705/3488 :banana:
--- 3DM OK 14221 :banana:
--- PiFast OK 52.50s :banana:

conclusion is that it new BIOS gave me extra 5mhz in 3DMark and made PiFast run @ 240FSB.
also, oddly enough, PiFast, 3dMark2001 and Sandra showed some improvements over d23_3D Fire with 2x512 as well as 2x256 kits.

even though it seems that this patch doesn't work the way it should it still changes something. so there's some more to do...

later i take a look at Prime95 stability...

great work TicTac, and greets to Pinczakko :toast:

[tictac]

nice result bachus... :thumbsup:

i'm afraid many doubt the command per clock register address.... that i tell them.. :(

[HaLDoL]

great tests bachus, have you tried going higher than 240?

[bachus_anonym]

Originally posted by HaLDoL

yes, but the highest that gives me minimum stability (full run of 3dmark2001) is 246FSB with 2x256. and that's it, at least with 3.45vdimm... i can push it higher, to around 3.6v but then vdimm fluctuates as hell !
Originally posted by TicTac

well, u see i also suspect that this may not be CPC, coz when i start WPCREDIT values at PCI Bus #0, Dev #0, Function #1 and offset 84-87 are "F3 13 0F 03" and not "F3 13 0F 23" as when DFI has CPC Off...

[HaLDoL]

I flashed D24_R3_ED_CPC and did not get any fsb improvements. Still maxed out on 265.
Good enough for me though :D

[tictac]

265... screenies plzz .. :D

3d mark orb link :D

[HaLDoL]

http://kaine.studentenweb.org/265fsb.jpg
http://kaine.studentenweb.org/sandra1.jpg
no 3d yet :)

[tictac]

em.. multiplier 8?

i want multiplier higher than 10 :)

[HaLDoL]

why? The only way to determine your max FSB is with a low multiplier. It only stresses your memory and the memory controller of the board, so you can avoid cpu limitations.

It seems that 265FSB 1:1, dc and cpu int enabled is the maximum for my NF7. This is probably the case for all NF7 boards (maybe some good boards can do up to 270).
But I don't think an NF7 can do more.

I'd love to see someone who can do better than 265FSB, 1:1, dc, 2-2-2-5/11 timings and cpu int enabled, but as for now the conclusion is that under the above conditions an NF7 can't do more than that.

I'd be very happy if someone proves me wrong.


PS: And if you want I can give you benches at 10x265 and 10.5x260 (cpu limited).

[tictac]

i want 10.5 x 265MHz... :D

[Bulldog20]

http://www.bulldog.34sp.com/cpuspeeds/260FSBisoftmem.JPG

Best I could do on my Nf7 V2, using the sub-zero bios. Not 3dmark stable. Same old problem tbh, High this, no high that :D

Just drop the FSB and up the Vcore. Voila :D

http://www.bulldog.34sp.com/cpuspeeds/Isoft3.1gzCPU.JPG

Must try CPC patch of yours when I get a minute :)

Nice to someone keeping the Socket A alive and kicking :thumbsup:

[FlyingHamster]

so u guys who are hitting these high fsbs (250+) have CPC disabled? wuts the max u can get with it enabled?

does it decrease as much performance on your boards as it does on Infinitys?

haldol- wanna see that 10.5x260 bench man. :D

[IvanAndreevich]

Heh.. I'm gonna test it out :D

[zz64]

Anyone been able to dl the bios? I been trying all afternoon here in cali

Atleast for me it didn't make any difference, I can run superpi at 250 cpc enabled and I think it was 252 disabled soo... but I think it's my ram that holding me back, 11-3-2-2.0 3.2v at 250 I'd say is pretty good for CH-5 ;)

[DarkManX_BG]

So if I understood this correctly, I don't need to disable CPC for my single sided 256MB HyperX3200?

[Joe_the_tulip]

if you disable it, you'll get more FSB! (between 2-5mhz is suppose, according to the other guys who tried the bios)

Hehe, 265x10.5 = 2782.5 MHz, no way my cpu will do that on air. But if someone could lend me his prommie .... :)
Anway next week I'll be getting a new NF7, an xpm 2600+ and some OCZ EB pc3700 mem. I won't settle for less than 270 FSB :D
Stay tuned ...

hehe... the boards won't let you bench at 270 unless you have ambients of -11°C (Lastviking) :D

265 has been max for all under normal circumstances...

Yes Noticed that, well 265fsb is still a damn fine overclock for the Socket A platform. Shame we will never see the socket A hit 300FSB out of the box.

Cheers

[uwackme]

OK Tic'y!!!

You almost have it....at least for me. I can now memtest using that CPC version at 230Mhz, 11,2,2,cas2.0 with 2x 512M BH5 without error. With stock D24 or D10 I cant go over 195-200Mhz error free (CPC default'd to ON).

So thats a huge breakthrough, and I boot ok, etc etc. I can boot to Windows at 220, and am still trying to find max 3D stability.

But caveat with ME.... my board always has trouble with post D10 bios's trying to go past 210ish FSB, regardless of the ram used, etc.

I can do 2x 256M, 2600+mobile at 10.5x245Mhz on D10 and same setup cant go past 225Mhz with D23 -24- etc.

Need further testing here, but I'd say this is SAFE for others to test with. Good going Tic'y!!!!

Now... can you do this mod to D10s4247? That would let me truly check out the CPC mod.

[SAE]

Yeah. It's a chipset/cpu/architecture limitation IMHO.

[uwackme]

Tic'y....

Confirmed 215Mhz 3D stable 2x 512M BH5 in my board....wouldnt do over 195Mhz rock solid pre-YourFix.

Im now at 230Mhz 11,3,3,2.5 Ill test this out.....11,2,2,2 works at 215Mhz rock solid. Stil along way from the 240Mhz on the LPuB but we are making progress. Too bad ABit isnt interested in fixing thier own product. How EMBARRASSING for THEM ;-)

[uwackme]

Well at 11,3,3,2.5 it does 225Mhz 3Dstable....230Mhz crashes 3Dmark. Farcry is fine at 225Mhz 11,3,3,2.5, and 215Mhz 11,2,2,2

So looks like ALOT of forward progress.

I'd really like to test the CPC fix as implemented here, in the D10 bios. My machine is good for a 20-30Mhz loss in FSB between D10 and D23.

Nice work Tic'y!!!!

[SAE]

Hehe. Uwackme, did you try any of the bioses I sent ya?

Would be interesting to see how they perform like in comparison...

[Rabbi_NZ]

Just posting to get regular updates :D

Well done to Tictac, trats, and all others involved!!

[uwackme]

Hey SAE!! Yes I tried them, in longterm test of 121 varient now, solid at 230Mhz, but 505 in general wont let me go much higher, while 131 or 121 original woudl let me go to 240Mhz. But at 230Mhz rock solid and not a smidge of lan/sound troubles yet.

Without question the LPuB/infinity let me get higher FSB with 2x 512M by a long shot.

Ive tested Tic'ys it is nice, Im on Trat/Triest version of D24 now, about the same top end.

As always ...MY... board doesnt like D23-24, it is a D10 board. I would really like to test these CPC fixes in D10 and see what is what. Something in the later bios's just doesnt agree with my NF7-S's, never has. D10 runs awesome on them though....sans the CPC issue.

But a 20-25Mhz improvement is nothing to shake a stick at.... nice job Tictac, Trats, Triest.

Nice. Those bioses are really stable for me... Erm. Seems like everybody not able to run CPC on prefers the 1-31... weird, cause for me it's too unstable in 3d...

[coil]

Im getting forbiddon when i click them links?

[uwackme]

I think Tic'ys D23 is a hair more stable for me than Trats D24.

Im thrashing this at the 215Mhz point, its rock solid Tic'y old buddy.

Now you can really make a friend with the same mod in D10, and also, there are a ton of people here with ASUS A7N8Xdeluxe boards using Uber1007 bios that desperately need the same CPC mod. I mention it just incase you need more droogie's to worship you :D

Agree'd SAE, the 121 is so far rock solid, I really like it, and it's great not having to worry about 1500mile service call to my brother when he calls :banana: :banana: :banana: :banana: :banana:ing about his new computer not working right, yada yada yada!!

LPuB, 2500+mobile, 1Gig BH5, 2x Raptor36G, 9800pro vmod'd, 550W ps, 8X+/-DVD burner, Superlanboy case, heatsinks up the wazzuu.... I think he has a nice system.

[FlyingHamster]

hehe SAE, u seen rickaye's (sp?) screenshot of him hitting 285fsb with his pc2700 on his infinity out of the box? then again, his timings were 3-6-6-11. :D

[IvanAndreevich]

tictac
Could you maybe make BIOS based on official #25 with the CPC turn off/on as one of the options? That would be crazy!

[HAYUP]

this is interesting...
i was always under the impression that DFI's CPC = Abit's CPU INTERFACE

I second that!

BTW Tictac, fill me in here. The file you made available to me is the BIOS itself? So that means, I don't need the "NF2AA131" BIOS I wanted in the other thread?

Can I flash using ABIT"s Window's Flashmenu or do I have to boot into DOS?

Tah~!

[bachus_anonym]

so i just flashed back to d23_3DFire and everything is OK now...

this is weird... this new BIOS just does not let me boot above 225FSB... i have L12 mod done and (it may be ridiculous) i start to think that maybe that and "wire mod" and "L12 Bios fix" don't play well together...

[tictac]

i think so coz that screeshot i gave u done with no l12 mod

on pprevious bios he stuck @ 206MHz

now 235MHz :)

guess what, TicTac....
i flashed back to d23_3DFire_r2...

i removed "wire-mod"... after Load Optimised Defaults" my mobile booted at 6x134 (800mhz)... with d23_3DFire, wire-mod and same procedure it booted at 6x166 (1000mhz)...

since your screenshot shows Throughbred, i decided to swap CPUs... with wire removed i put my 2700+ and it boots fine at 233FSB so far...

so my conclusion is that this new BIOS doesn't recognize mobile CPU the way it should and that what prevents it from POSTing at bove 225FSB...

EDIT: with d23_3DFire_r2, TBred 2700+ i got no post at 238FSB... flashed back to d23_3DFire again and typing now at 240x9... new BIOS has definetely issues with mobile Barton...

[tictac]

nice find... thanx for testing it :)

looks like mobile L12 aint working :(

[Rabbi_NZ]

tictac,
on the D24_ED_C18 with "built-in L12" and Infinity timing (i think?) my L12 mod is recognised fine and i get a massive FSB increase... maybe its the new BPL that's p!ssing the board off...

[IvanAndreevich]

tictac
I have the L12 mod done physically. Will I have problems with my mobile @ high FSB with the R2 bios?

[sikkony]

Tictac, I tried the d23_3DFire_r2 BIOS but it won't allow me. It says, my AN7 is not compatible with that BIOS. How do I get around this?

[tictac]

sikony.... it is nf7s bios rev 2.0 not an7 bios...

This D23 3D Fire R2 still running on Original Abit NF7S romsip...

:)

yeah this will lose to D24 ED C18... which actually running on DFI 4/29 Bios 3rd table romsip...

so make ur choice... :)

These Bios versions are for NF7/NF7-S 2.0 boards. There is no official Bios25 yet for Version 2.0 NF7(-S). Bios25 is a bios for NF7(-S) Version1.0, 1.1 and 1.2. ;)

Tictac,
could you make a BIOS version exactly the same as this, EXCEPT with Command Per Clock Disable... I want to test if it helps my 1GB DC

[IvanAndreevich]

celemine1Gig
You're right. Someone told me there is one for NF7-S 2.0 and I believed :D

tictac
Can you answer - will there be problems if I have a mobile but my L12 is already done physically?

[Rabbi_NZ]

not from my experience... I ran D24_ED_C18, which also has the built-in L12. My mobile is L12 modded to 166FSB and it didn't matter... still worked perfectly.

[Joe_the_tulip]

3d fire rev 2 eliminated my l12mod! now i can just push as far as before the physical l12mod (231 with 2.1VDIMM) but it helped me to find out, that my 1700+ does 2640 primestable with 2.0Vcore and watercooling. 2536 is stable with 1.78V and watercooling.

but I did the l12mod for 1700+ only (just one wire alongside (right expression? :D ) the condensators)

[uwackme]

Rabbi.... Tic'y sent me a D23-3D-R2-cpcoff version. It works great! I popped it in a buddy's system , he was limited to 200Mhz 11,3,3,2.5 with 1Gig CH5 (HyperX3500) and VIOLA! 220Mhz 11,2,2,2 with this bios. Im sure it can even go faster but he needs stability more than max speed.

As my board likes D10 better, Im still on Trats D10-cpc319 version.

My BH5's are at 220Mhz 11,2,2,2 but in DFI LPuB they do 245Mhz 11,2,2,2 so there is still alot of room for improvement on the ABit end.

Though I hope Tic'y can get a D10 plain Mikeypadge with cpc off.

I think the ORIGINAL only D10, with cpc off, and (mize-well) sata4247 would be the best for my system.

Many thanks again to Tic'y and Trats.

D23 3D-FIRE Reversion 2, does it work, any screenshots with high FSB:D

[uwackme]

Well my buddy Tony with 1Gig KHX3500 was stuck at 200Mhz 11,3,3,2.5 until the D23-3D-R2-CPC, now he is 220Mhz 11,2,2,2 and has room to go up, left it real conservative cause he hates crashes :D

[tictac]

emmm.. have u tested D24 Soft Ice yet.... ? :(

[mars]

a funny thing has happened to my board
ive spent the last few days flashing all sorts of different cpc off bioses from the modbios 1-3 then d10 all of them, played alot of memtest with vdd from 1.6 - 2.0v with a vdd modd
yesterday i decided to remove the modd to test with lower vdd
guess what?

my vdd is permenently overvolted and i cant seem to get the original values
my 1.4 gives me 1.51v
1.5 gives 1.65v
1.7v gives 1.87v

i have no idea how I did this
but i figure another flash may fix it
but I havnt done so yet

[The Virus]

I dont know why you guys have problems running 2x512 sticks on your nf7's because my board can run 222fsb 2-2-2-5 without any problems . I have tested this with memtest and passed 10 loops without a singel error. My NF7's rev2 is one year old so im guessing that all new boards are crap for now and forever.

[LilGator]

Some people consider 222fsb 2-2-2-5 to be a problem ... :) But these old NF7s indeed are something special ;)

My VDD is overvolted as well, but I used a pencil :p:

[uwackme]

Well, the "good" set of 2x 512M in my NF7-S does 225Mhz 3D stable, 11,2,2,2 cpcoff. D10-4247-cpc319 bios from Trats.

Same ram in DFI board does 250Mhz 2D, 230Mhz 3D....250Mhz 3D (single channel each stick alone).

There is "something" in the timings in the bios code (not something we get access too) that pisses off the AGP accesses at high FSB in dual channel. Single channel no problem, but dual ugh.

I just have the feeling it is a small timing issue that a tweak in the settings could fix, but we have NOONE in the world working on it at the OEM's or NVidia.... they have moved on to A64land, etc.

Oh well.

[The Virus]

Have your guys tried to raise the AGP voltage when ocing??? I believe it helps alot when comes to stablity of the total setup.

Virus, what RAM are you running?
I think there are a select few mem brands that don't suffer this issue as much... I've tried 4 mushkin BH5 sticks and 3 cosair BH5 sticks, all PC3500, and the cosair consistantly outperformed the mushkin by a nice margin...7-15MHz

I got 2x512 Corsair xms PC3500 C2.... PURE BH5 ,, u cant find these anywhere anymore ....been sold out many months ago.

Im using regular NF7s bios and im doing 222fsb 2-2-2-5 , 12x222fsb with my mobile 2600xp.......

interesting you say that, I'm running 2x512MB XMS3500C2PT (BH5) myself @ 11.5x228 2-2-2-11 100% stable with CPCON D23_3D_R2 on a brand new NF7-S (blue dimms etc)... I tried trat's D24_ED_C18_CPCOFF and got no benefit so I'll check out tictac's D23_3D_R2_CPCOFF tonight in the hopes it gives me an improvement...

[uwackme]

Yes, on stability testing, as I push it, I go till I have a problem, then I stay there and diddle every setting one at a time, through the entire range (of what would make any sense). So I tried all AGP settings, Vagp, 8x 4x fastwrite on/off, SBA on/off and AGP latency. None made a difference to what is happening now for me.... only FSB matters. Go over a certain point and 3D fk's up, but none of the "diddle-able" things makes it any better.

This is all at the upper limits on a DFI LPuB.... I aint got an NF7 that can be of help in this top end stuff.

[Rabbi_NZ]

D23_3D_R2_CPCOFF and D23_3D_R2_CPCON perform exactly the same in terms of FSB for me, but D23_3D_R2_CPCON scores ~400 points more in 3DMark.
Maybe it's not related, but the majority of people having success with NF7+2x512+Tight Timings are using Cosair BH5... there could be something in it.

Now unless another breakthru is made the only option left for me is to bite the bullet and buy a PCI SATA card so I can use the D10 variants...

[uwackme]

Its funny but the exact way that the rams are connected on the sticks could always be slightly different on the Corsairs. Wonder if they hocked up some address/bank select bits slightly differently.

Guess we'd have to trace out the stick-vs-chip signal connections to verify they were the same as say a Kingston.

Also, maybe Corsair used more caps, and difference resistor layouts to improve stability.

Pleaaaseee !! Pleaseee !! A L12 mod on the bios for the mobiles !! \o/ !!

D23 3D R2, D24 ED, D24 ED C18... all have built in 200FSB L12 mod. Your CPU wont show up as that, but it WILL use the 200FSB chipset timings ;)

tictac,
what's this D24 Soft Ice about?
i will test for you if you need more BETA testers :D

[IvanAndreevich]

tictac
Is it impossible for you to make CPC an option in the bios? Like CPU Interface - enable/disable, CPC - enable/disable..

[uwackme]

Yes, that would require actually altering the sourcecode and re-assembling the module. Its alot to ask of someone who doesnt have the sourcecode to work with.
The tweaks they do are simply using different modules (self contained code sections, with different settings implemented within) and re-combining them to try and get the best mix of off the shelf settings.

They also have done a small amount of assembly hacking, adding small code segments wedged into the existing assembled bios code. But going the next step, to disassemble entire modules, and re-design/assemble adding actual features, thats a hefty project. Especially without the NForce2 technical reference.... so you dont even know what it is you are diddling. With the NF2 tech docs, you could fill in the symbol table for the disassembler to know what is what for all the motherboard's hardware, and THEN it would become alot more feasible to redesign the bios for our needs.

Again, it is PATHETIC that the modding community has to be doing any of this, stems from absolutely ZERO OEM cooperation with customer needs.... with the bright exception of Oskar Wu and DFI. But even Oskar is off doing A64 stuff now, so we may never get his help again.

[Rabbi_NZ]

for anyone not running D10 and using 2x512MB BH5 I recommend:
D24_4247_ED_D14bpl (http://abducted.henslfuk.nl/files/bios/d24_4247_ed_d14bpl.zip)

Got me from semi-stable at 228 2-2-2-11 to 100% stable at 229 2-2-2-11... not a big jump but welcome all the same. I also gained a marginal improvement at the same clock rates.

[LilGator]

"for anyone not running D10 and using 2x512MB BH5"

Is that for anyone not running D10 and also NOT using 2x512MB BH5? Or for anyone not running D10 and IS using 2x512MB BH5 ? :p:

Which bios were you going from semi-stable at 228 2-2-2-11 ?

[speedyaxon]

tictac and others responsible for these bioses...

I would like to officially thank you for your hard work. Your work has allowed me to hurdle over my 200fsb wall. I'm now at 216fsb, 2-2-2-11, cpu interface enabled.

Thanks much man and keep up the good work.:toast: :banana:

[sikkony]

Yes, he has done excellent work. I can hit 240FSB on my AN7! Very nice indeed!

So my CPU was like 11x240fsb. Great stuff!

are you a programmer by chance? LOL
I meant for everybody that is (NOT using D10) AND (Using 2x512MB BH5).
I am coming from D23_3DFire_R2_CPCON, which was my previous favourite.
CPCOFF BIOSes do no good to my rig, they lower my performance per-clock and leave my max FSB exactly the same as before.

[LilGator]

ahh, ok ;)

No, not really a programmer...yet

thats where i'm headed...

[The Virus]

Regarding my privious post i meant to say that my board does 222fsb 2-2-2-5 with original Abit bios 23........NO SPECIAL BIOS.
