Failed to Post @ 166Fsb, Whats holding me back??

[OverVolt]

As title says i tried to set fsb to 166fsb from my previous 144fsb. After i set to 166fsb it failed to boot into windows. Then when i rebooted to change the fsb back to 144 it wouldn't post. I reset the CMOS and now i'm back at my lousy 144fsbx10.5=1.5Ghz Here's my stuff let me know what u think is holding me back
----------------------------------------------------
GA-7DX+ by Giga-Byte here's a linky to it
XP1600+ AGOIA 2002 week 6 1.775v
Samsung Pc2100 266Mhz 2.73v Cas2 set @ 2.5 4 stabilty
300w Antec PSU
Coolermaster HSF with massive airflow from case fans (40c idle, dunno underload can't get mon prog to work)
AGP bus is locked but i dunno about PCI, but i'm assuming
Soundblaster Live! 5.1 (heard this doesn't oc well)
Then ur usual hd's/lan/cd-rom/RW/floppy/usbcard ect. ect.
linky

The problem could be you only have PC2100 ram which is 133Mhz not 166Mhz
and you only have an XP1600+ so at 166Mhz that would be 1743MHz and i bet your crappy coolermaster heatsink cant handle that.
also 40C at idle is HOT. I have a 1800+ tbed @1950MHz and its 40C at full load for 8 hours.

oh and your motherboard is like the slowest amd 760 chipset board they ever made.

If you're serious about overclocking, newegg has some refurbished kt333 and kt400 boards for about $49 shipped, including soltek. I also suggest a better power supply. They had some refurbished antec and enermax ones recently for $28-48.

Ya i was always serious about overclocking but i've never had the right stuff to get a decent overclock. i had to make this on a tight budget ($650). guess i'll just have to be content with what i got for now.

It can! i've never had a problem with stabilty/heat.

It's AMD761 chipset faster than my old celly on 66fsb

get yourself a epox8k3a or an asus a7n8x and some nice pc2700ram, then you should have no problem, oh yeah and a better cooler

 

[nealh]

you can not compare temps between mobos let alone different computer setups....if you ever read one of Mikewarrior's post you would have a better understanding of this issue...different mobos will give higher vs lower temp ..

the key issue is stability ....if you o/c and temps go up beware ..get a new HSF but this will not always buy more speed....sometime a chip just hits the wall or another hardware component is the limiting factor

 

[rogue1979]

Your Ram may not be up to snuff, and the 761 chipset has difficulty reaching 166MHz stable, more like 150-160 is a normal overclock for that chipset.

Your CPU may not be able to overclock that high. I have 3 sticks of PC2100 DDR that can run up to 170MHz FSB at CAS2, so your memory may not be the problem. If you get a new motherboard you can run at 166MHz or even 200MHz FSB with the PCI and AGP at stock frequencies.

If you really want to hit 166, upgrade in order:
1. mobo
2. RAM/PSU
3. HSF- however, try lapping it if you havent.

You said that you went straight from 144 to 166... try moving a little slower... 1 FSB at a time...
Unlock it, or have someone unlock it for you... (PM me)

It's either your ram, or your hard drive.
With my Crucial PC2100, i can always only hit 147FSB max.. and when i tried to boot on another hdd, i can hit past 166MHz. Most hard drives can't handle very high PCI speeds.

I'll try the 1fsb at a time and see wherei get to. as for the ram i'm going to take a stick of 2700ddr out of my dads pc then try again. i'm worried if i go to high i'm going to get some data corruption since i'm not 100% sure my board has pci locks. i might just buy a new mobo- this one is kinda old anyways.

I tried to unlock before but it was a disaster- i used a pencil and super glue and took a try at the L1 bridges and nothing happened!

It's either your ram, or your hard drive.

I'll try taking out my other lame hd- a quantum 15gigger

Right now @ 148fsb, i'm afraid to go past since if i dun have pci locks it'll go past 37.9Mhz (the corruption zone for pci stuff i think)
