C2 900 cDO

[RisrullarN]

i have quite a problem..
my c2 900 is cDO stepped but i can only reach 990mhz
im using an abit board, BP6
1x128mb PC133


when i run@990mhz it works fine.. 1.65v (def. 1.75)
fulload temp : 30*C

next fsb step is 124 and that gives me 1120mhz..
when it loads windows i get errors like "bla bla bla couldnt load".. the usual stuff.
well, okey i thought, lets upp. the voltage a bit.. tried 1.85.. same thing.. tried 1.95 .. same thing! whats the prob? i was hoping for ATLEAST 124 fsb not to mention 133 (1197)..

the temps are never above 35*C

Hi RisrullarN,
First of all I suggest to use MotherBoardMonitor to check your system temps, that you can found at http://mbm.livewiredev.com/
if your temps are confirmed, well, they are very good, so not an heat prob.
Try to go with a Fsb of 133Mhz, much better for the Pci/Agp peripherals and your Hd's, for the freq. in the specs, and also try to set the more conservative mem settings: Ras & Cas delay on 3.

At the moment I'm downloading the user manual for more info & support :)

[RisrullarN]

memory is set to cas 3-3-3 and used to be in a pIII 733 (133mhzbus) so it cant be the mem.. i have tried removing all my pci cards without success... it posts fine @ 133 fsb but memory sometimes counts wrong .. scandisc screwed up my disc yesterday when it "restored systemfiles" after a few failed bootups..

[The Doors]

Please, what kind of Vid card are you using?
I ask you coz you can set into the Bios only the Agp bus on 1/1 or 2/3 of the Fsb, so at 124 you got 83.6, very far from the specs of 66.6Mhz, and not all the vid cards can handle this freqs!
Try to go with another Vid card, if possible, like an old Pci, generally are rock stable and good to understand where's the prob :)

What do you wanna mean with 'but memory sometimes counts wrong'? for the Hd's prob, well probably depends by the Pci bus that with a Fsb of 124Mhz is around 41.3Mhz, very far from 33Mhz (the spec)!

[RisrullarN]

im using a geforce 256 ddr (asus 6800)and thats not either the problem.. ive run this card @ 110 without any problem.. infact.. atm im running @ 110fsb and 1/1 agp.. np.. worx like a charm..

the memory issue...
well, when i boot up@133 and the mhz shows bla bla bla .. but when the memory counts up (128mb pc133) it countrs wrong... sometimes 70mb, sometimes 2mb.. etc etc..
the hdd worx fine @ 83 and 84 bus.. so i dont think its that either.. :[
my only suggestion is that my mem is broken in some kind of way.. dont have another i can try either atm :[

other ideas?
thx alot for all replies !
and sorry for my english.. from sweden :]

[The Doors]

Uhmm... it seems to be a mem module prob, it's really strange this kind of wrong reports at Bios Post, well no prob, at the moment the mem modules are so cheap :)
Onestly I haven't other suggestion, for your Vid card well better to go with 2/3 Fsb, 110Mhz are really too high, even if it works fine. About your English, well, don't worry is good enough, and mine isn't much better :D Good Luck and let us know your progress.

[RisrullarN]

yep... i think ill have a go for a new mem..
but i need one that will do 2-2-2 and 4 way inteleave@133 fsb.. got any suggestion ? need it cheap too! and 256 ram.. will that do? only gaming..

[The Doors]

Personally I'll go with 1x256Mb, better than 2x128Mb, of Crucial Pc133 Cas2 that generally work at 150Mhz Cas 2-2-2, for more info take a look at http://www.crucial.com/uk/index.asp or http://www.crucial.com/ :)

[RisrullarN]

hmmm... thx for all replies!
i tried upping to 124 mhz yesterday night.. it ended out my harddrive was a mess! all files on different places, crashes, bluescreens etc etc... (this was after ive tried 124 since it failed to boot)

why doesnt my hdd make this speed?

[batboy]

Sounds like your PCI bus is running too far out of spec. The harddrive controller runs off the PCI bus. Some harddrives do well overclocked (like IBM 60GXP) and others hate being overclocked. I have scrambled a harddrive before from running the PCI bus too high. Usually, the drive will be ok after you reformat it and reinstall the operating system. I've never had much luck getting any of my computers I've had to run at 124 FSB.

Why would you run the CPU voltage at below default? That's asking for stability problems. I would also consider doing more cooling mods. The temps you mentioned are probably system temps since I don't think those BP6 mobos had a CPU temp probe. If so, those temps are a bit high.

[RisrullarN]

hmmm... well.. if i set the fsb to 133 things will be ok?
but then my crappy mem. freaks out.. ill get some new ones..
bp6 has temps.. but the ones in bios are not correct.. im using hmonitor (bp6.com) and my cpu temp under load is 28*C.. its rock stable @990 with 1.65cv..
my cooling is a large hs (homemade) and a 80mm fan .. and i have good circulation in the box. m/b temp is about 26*C under load..

some quality ram and fsb @ 133... this will do the trick?
ps.. the funny thing is that my hdd has no problem with 83 bus (like 41 pci freq?) ?
heeelp :] thx alot.

[The Doors]

Theorically Yes,
but try to compare the system temps with MotherBoardMonitor, and go with the new mem module @133Mhz of Fsb to forget probs with the Pci Bus :)

[LutaWicasa]

Kinda confusing, cause actually with the BP6 when at 124 fsb the pci is at 31 MHz. Out of curiousity, why not try running at 93 fsb. This is at a speed slower than you know it will do stably so should work. But with the BP6 running at 93 fsb the pci bus will run the same as 124 fsb (31 pci). Mayhaps, something doesn't like the underclocked bus ??

[The Doors]

I'm sorry but I disagree with you LutaWicasa,
coz from 100Mhz to 132Mhz the divider is on 1/3 and only from 133Mhz switch to 1/4, so at 124Mhz the Pci bus is on 41.3Mhz (1/3 of 124).

[deez]

Sorry Doors but I disagree...my BP6 runs at 1/4 divisor at 124 FSB and 133FSB

RISULLARN...It may be a problem with the Highpoint ATA66 drivers. There are driver updates for those that may fix hard disk problems. Also what bios are you using? I'm using RU from Abit and everything runs fine.

One final question...did you do any mods to the BP6/chip or are you using Neo s370 or other adapter?

[The Doors]

Thanks for your info deez,
is it possible to use 1/3 & 1/4 at 124Mhz?

[RisrullarN]

hmm...
i changed from using ata66 > ide since it was SOOOOO SLOW with ata66 (Not correct drivers i guess)... im using some kinda weirdo bios from bp6.com.. what is "RU bios"?

no, no mods.. but ive got a fan blowing on the chipset hs.. thats all..
using ppga > fcpga adapter between socket & cpu..
and last question.. at what cv will i be able to reach 133 fsb? approx?.. will 1.95 do?
thx..

[deez]

Doors...no only 1/4 divisor...BP6 is strange has settings up to 110 then skips to 124(1/4) then 133(1/4) only selections for AGP are 1/1 or 2/3

Go to www.abit.com.tw or here http://www.abit.com.tw/eng/download/bios/bios-bp6.htm and download bios RU...those bp6.com bios mods screwed up mine

1.95v sounds a bit high...definitely wouldn't go above that

Different mobos offer different features. With my BX6r2 you can utilize the 1/3 or 1/4 at 117 fsb, but only the 1/4 at 124 fsb.
It depends on which clock gen and if the board manufacturer offers you all available options. This is why Softfsb and CPUfsb can offer some peeps "hidden" fsb options.

[The Doors]

Thanks for the info LutaWicasa & deez,
and sorry for my wrong disagree :D this is really an interesting and usable feature.

[RisrullarN]

OMG ! i installed the latest bios from abit.. and rebooted and loaded default...

i got into bios, and changed the fsb to 133(1/4) and the agp to 1/2.. cv was set to 1.95!

posted fine, memory counted correctly.. everything was fine until it loaded windows when i got some error messages..
ohh.. well... better than before..
so i changed fsb down to 124 to so if it would work better.. same thing.. but scandisc started and safecopied my systemfiles as always.. and if u dont hit reset with the speed of light scandisc messes my disc up totally.. but i was fast enought this time. *phew*
temp was @ 31*C @ 133 w/ 1.95v.. so temp is not an issue.

and now.. i dont think it the memory either... :< someone?

[LutaWicasa]

Now it might be worth trying a fresh os install.

[RisrullarN]

just did yesterday after scandisc screwed up all files :< so thats not it either..
ive reformated 4 times this week.. just to fix this #()%/"¤/Q%#) cpu :]


well. ive been in windows once @ 124 fsb but it crashed almost immediatly..
can it be that the cpu needs more juice than 1.95v?

[The Doors]

Absolutly not for me, generally it works rock stable at the rated voltage or around 1.8-1.85v.

[LutaWicasa]

Well, when I first went up to 1054 with my 566 I had to run at 2v for a while. Now I've backed'er down to 1.85v.

Just be real sure on the cooling.

[deez]

Sounds like the bios worked for you...maybe your cpu just doesn't want to run that fast with your current cooling. Or your Windows just got corrupted again...i'm sure that bp6.com bios didn't help anything out. one more format may be in order

I know my 566 will do more than 850 but I have a cheap HS on it and cant get it running solid at anything faster than that right now.

[slick306]

I was running my system at 133mhz bus 1/3 PCI, and everything worked fine. I have a Western Digital hard drive, 3com ethernet, TNT1 (And radeon 8500), tekram dc390 SCSI controller, sblive. No problems at all.

I wasn't aware that the BH6 1.1x offered anything other than 1/4 at the 133 fsb.

[slick306]

Yeah it doesn't. I had a bh6 rev 1.01 but I traded a friend to get the extra bus speeds, now I have the bh6 rev 1.2. On the 1.01 it just had the 1/3 at 133mhz, it ran fine.

[RisrullarN]

well...
either its the hdd or the mem right?
but how can it be the hdd ?
im gonna buy some new memory soon (mosel vitelic guaranteed for 133cl2)..
i hope this will do the trick but i really doubt it though.. :[[
does anyone has any suggestions? ive tried everything! the h/s is not even a bit worm when 1.95v and 1197mhz...
its below 30.. (positive)

heeeeeeeelp! =] thx..
if my cpu just.. sux.. ill leave it back and get another one from another store.. 900@1000.. :] what an O/C!

[The Doors]

Onestly I don't think it's your Cellie,
try with a very deep surface test of your Hd with Ndd or the crappy Scandisk, it's a long process, I know, but it can discover many probs, like possible bad sector.
