View Full Version : got new 2.4c(sl6z3), wont go over 300fsb??
Well i got the 2.4c today and it overclocks very nicely until i try and go over 300fsb... It runs 3dmark no problem at 300fsb(3600mhz) at 1.65v. As soon as i go over 300fsb it wont go into windows, boots up fine but wont go into windows, and ive tried up to 1.75v.
I dont think its the volts and im running my mushkin pc3500 level II using 3:2, putting 3.0v into the ram just for good measure, so im sure its not the ram.... :)
Im using the latest 1014 bios for my asus p4c800-e, should i try a different bios??? I cant find any other bios other than the 1010... Used to like the 1007 with my p4c800 deluxe but i cant find that bios for this p4c800-e....
Is there an issue with this board going over 300fsb???, Im pretty sure the cpu will go much higher because ive only put 1.65v into it. Cooling is not an issue because i have r404(by herefishy) cooling the cpu, cpu stays colder than -40C.....
Any help is greatly appreciated:toast:

It most probably isn't the CPU but the motherboard. All 865/875 motherboards start their major issues at 300FSB.
For starters, did you set Vagp at 1.7v and AGP/PCI at 72/36? (Given that your devices can take that!)

No i havent tried that, but i will definately give it a try:)

try clockgen once in windows...
well setting the vagp to 1.7v and AGP/PCI to 72/36 didnt work...
Same thing it boots up normal and gos through the boot screen and then right before where its supposed to show the welcome screen it just goes black and hangs there:(
What is clockgen??????

Clockgen is a software based overclocking program. You can try it if you like. Just boot at a stable setting and then use it.

Clockgen is a really nice utility making it possible to clock from within Windows...

i set the vcore up to 1.75v and booted up at 300fsb(which it runs stable with 1.65v) and used clockgen to up the fsb to 304 and it blues screened and rebooted:(
Hmm, it seems whatever is stopping me from going over 300fsb i cant figure out how to fix it:confused:

It IS possible that the CPU hit the MHz wall of itself....however I find it unlikely to happen so sharp.
Is there any other well powered system like yours that you can try the CPU in? Like at a friend or something?
no there sure isnt, im almost positive its not the cpu.. I mean i can loop 3dmark '01 at 300fsb @1.65v, and yet it wont run at all at 304fsb, no matter what voltage?? That just doesnt make any sense...
I guess i will try a few different bios just to see...

When you tried clockgen, you DID have the AGP/PCI and Vagp where I told you, right?

Hmmmm...
Weird question coming. Do you know where your motherboard is made at? It should be written on the box I think.
it says taiwan but thats just where asus headquarters is i assume
I was just reading something that said alot of times the apg\pci doesnt lock above 300fsb.... WTF is that all about... Is that true???

Try relaxing your timings
Also it COULD be your CPU. Even though your using thee SL6Z3 stepping no overclocks are guaranteed. I know some people are getting 3.7Ghz~4Ghz but that is NOT everyone.
3.6Ghz is very nice for a 2.4C IMHO, thats a 1.2Ghz overclock. Besides you wont feel the difference at all without doing benchmarks but I don't think this is what you got the cpu for. Id say be happy with what you have or sell the cpu and go get a 2.8C or 3.0C
tried relaxing the timings but it didnt do any good.. Im about 99% sure its not the cpu. It has something to do with going over 300fsb.... Was just reading another thread that alot of people are having the same problem, hitting a wall at 300fsb.... There has to be a way to go higher, maybe a different mb??

hey ccc, nice to see you over here on xs :)
:toast:
did you ever get above 300 on that board with another chip?
tried raising the pci/agp speed a little already?

No the other chips i have are a 3.0c and a 2.8c, and there was no way i could get them over 300fsb because the cpu itself was my limiting factor
Yah i have the vagp at 1.70v and the apg/pci at 72/36..... I bought this 2.4c so i would have something to play with using my new r404 phase cooler.... I know this chip has a ways to go but this not being able to go above 300fsb is just silly.... There has to be a way:confused:

there was a bios bug on some boards, wasnt there?
hmmm
did you try a little higher? 305 maybe?
yah ive tried 301, 304, 305, 310, and 315...
Im going to flash back to an old bios and see what happens....

Try booting to windows at 295fsb and agp/pci at default..... tehn when you use clockgen, raise teh agp/pci there.......

Well CCC your right on that too. I forgot to add that in my post. It is true that some motherboards tend to hit the wall at 300fsb. What I would do is try to watercool the nb or just try a differernt mobo. Give the MAX3 a shot or another p4c800-e

Taiwan is also a manufacturing plant....if it was Chinese I would worry, but the taiwan one is supposed to be good.
Yes, the AGP/PCI clocks have trouble over 300FSB with all motherboards carrying those chipsets. That's one of the reasons why over 300FSB you will never be 100% stable with any motherboard. Even if you boot and be able to benchmark, stability will be at the very edge always. You can't run over 300FSB 24/7. That's the reason why people with super cooled systems prefer the 2.8C, at 300FSB you hit 4.2GHz which if you reach that it is as far as most CPUs will get you.

btw, that's a failed P4EE.;)
DO NOT attempt to take the heatspreader off!
looks like Intel have got the core fixed to it pretty well on those SL6Z3's.:(

WOOHOOO, luihed you the man:toast: Up to 320fsb so far, didnt realize it but the wife left the patio door open to let in some fresh air and in doing so let in the moisture:( Started noticing some condensation on the epavorator so had to shut it down for a while...
But so far im up to 320fsb, ran lobby low with stock XT and got 310 or so. Not to bad for a 2.4c and a stock XT:)
Thanks again everyone for the help, especially luihed:D ...
Maybe try and max this 2.4c out tonight, see if i can get 4gig out of her:banana:

Overclocking the card won't do anything for Lobby Low as thats all system speed, but good results though.
