View Full Version : celery 850 wont run higher than 132fsb
elo
im kinda a newbie ocer so some of the stuff i say might be wrong
i have a celery 850@1037 on a asus cusl2-c atm. and i wanna push it to about 133fsb...but when i change it to 133mhz it wont boot up...i tried fiddling with the fsb:memory:pci ratio...but still wont work...anyone got any ideas?
and what is an acceptable temperature for a fully oced cpu?

For the temps you want to stay under 50c, low 40's would be best...
can you post some more about your system, the more info you can give the better chance of us helping you to 133..
Oh and Welcome to the forums :)
Have you downloaded the latest bios. I had problem with a celeron 900 till I downloaded the new bios.
i just upgraded to v1009 bios and still it wont run @ 133fsb..
ok heres a lil more info bout my pc
celery850@1060 125fsb 42c full load 1.85v
384mb pc133 ram
asus cusl2-c 1009 bios
asus v7100 gf2mx
sb live
so can anyone help?:D :D :D ...i really wanna get my pc to at least 1.1ghz:rolleyes:

Sounds like it could be a cooling problem what type of heatsink are you useing?
globalwin wbk38 with that really noisy fan:D
What brand/type amount of memory?
2 hyundai sdr 128mb pc133 and 1 apacer sdr 128mb pc133
Try with just the apacer in the board.
tried with just apacer ram...didnt work:mad: :mad:
Same thing no boot at 133?
Try with just the hyundia.
If thats no help raise the cpu voltage a step but watch your temps.
Also what stepping is your cpu a cC0 or cD0?
If its a cC0 your probably at the cpu's max speed :(
mm ok.....how do i find out if its a cco or cdo?
http://www.cpuid.com/
Go there and download Cpu-Z.
132 fsb is a good overclock if its a cC0 1122mhz.
Raising the votage to 1.9 might get you the magic 133.
ok its a cC0:( :( :(
ive tried 132mhz....but it freezes alot...temperature was alright...sub45C tried put voltage on 1.9 and 1.95....still no go..
could it be like the high pci freq.?

I know its not a cD0 but din't freet cC0 are very nice CPUs just not as good as a cD0

Do you have SiSoft Sandra?
It will probably be able to show your pci bus speed, I think 124 and over is 1/4.
Here is a link to Sandra.
http://www.sisoftware.demon.co.uk/sandra/
Look in the motherboard section of the program after you install it.
ummm it doesnt really say in sandra....but like in my mb bios it shows when i get it to 132fsb the pci freq. is about 45 or so....thats y i wanna make it 133fsb coz @ 133fsb it runs @ diffrent ratios which makes the pci freq. 33:(
Interesting.
My 815 board has the settings like 3:3:1 =1/3pci-100mhz memory
or 4:3:1 = 1/4pci-100mhz memory.
Your board you cant select the 1/4 unless at 133mhz?
That sux :(
ummm i can sort of select it one im using now is 100:100:33
i tried 133:100:33 and 133:133:33 but it @ those ratios i cant choose to go below 133fsb unless i change the ratio to 100:100:33 and my pc wont boot @ 133fsb....so:( :( :( :( :(
I know having more than 2 memorys installed makes the timing default to 100 or something like that.
Maybe Sohryu Asuka Langley will read this and be able to help with the settings more as the owner of the same board.

Unless you hit your CPU's limit (which i guess quite not as youre runiing a very high PCI), WHere exactly does teh CPU fail, do you get POST or it just stalls?
after i change the frequency in bios and when the pc shuts off to restart...the cscreen would just go black and beeps couple of times then it would boot up with the default frequencies....

Okay, I just got back home, have a bit more time now.
Try these:
If you have 3 sticks of ram, remove one (the traces are too long with 3 sticks to run 133Mhz)
Set 133:100:33 and time your ram 3-3-3 7/9 and go down a bit more for sdram driving mode change it to strong.
Before rebooting, set voltage to 1.95v or whatever you think youll need to boot at 133Mhz, but keep it at 800Mhz. Reboot with that, check the hardware monitor to see if the voltage change took, then try your luck at 133Mhz FSB again.
If it manages to boot at 133Mhz, then shut down, take out your CPU, and VID Pin wire the higher voltage. May be a cold boot problem.
(I dont have to do this because i can POST at 1116Mhz @ default voltage)
If nothing seems to work, you may just want to Burn In your CPU for a while. I couldnt go past 1062Mhz until I used it for a while, Im experimenting with 1098/1116Mhz now.
If you can make 133Mhz FSB, you wont need the x86-secret BIOS as the FSB wont be out of sync.
Maybe this will help.
ok i changed those ram settings...but i dont understand that bit where u said to run ram @ 133mhz and leave the cpu @ 800mhz..or did misunderstood that..
the pc seems to run alot faster after that tweak:D :D :D

Urm, no the PC should run much slower because of the dumb down stability tweaks.
What i meant was, stay at default speed but at a higher voltage. Reboot with that, check the hardware monitor to see if the voltage actaully changed, then back to the advanced page, set 133:100:33 and try to reboot again.
o i c....ill give that a shot..ta

For booting up @ 133FSB you might want to use the wire trick.
VCore set in the BIOS of the CUSL2 motherboards (and maybe other ones with the 815 chipset) don't set the VCore right untill booting into the OS.
With the wire trick the default VCore will be about 1.85V.
Here's a link on how to do it:
