Overclock a celeron 2.4GHz to 2.6 GHz

[Dragona]

Hi i would like to know what ratios would i use to overclock my celeron 2.4GHz to 2.6 its based on P4 core and my mobo is Asustek P4xp-X i dont know if i can go furtherwith my processor because i think my mobo has a limitation to 2.6 GHz how many more fans would i need? if any i only use a heat sink atm not sure what temp runs at i got 512 Ram aswell if any of this helps :\

-Thanks in advance Ashley

Well, I looked up the specs on that mobo and have good news and bad news. The bad news is that you're limited to a max FSB of 133 MHz. The good news is that even with the 133 FSB limit, that will allow up to a 3.2 gig overclock with your Celeron 2.4 (however, that'd don't mean your 2.4 will actual overclock that high). The other good news is that you can lock your PCI/AGP to default speeds.

The 2.6 limitation you read referred to up to a 2.6 CPU was supported. This mobo is mainly for 400 bus processors and 2.6 is the fastest of this type available. I would think you have the potential of at least a 3 gig overclock.

This mobo is a strange breed because it allows both SDRAM and DDR RAM. To help you anymore, I'll need to know exactly what kind and speed of RAM you have. Also, you can probably do at least a modest amount of overclocking with just the stock CPU heatsink/fan, but I'd make sure you have good case ventilation.

hehe thanks

well i got 512 DDR, PC2100 Ram

whats the max i could go without need for an extra fan or 2 im gonenr buy some soon wen i get an order big enuff prob november.

and with the sdr and ddr you can only use one type at a time so its either DDR or SDR :( i thought great wen i first saw it but it turned out otherwise :( ah well :P

thanks for ure help so far

[Dragona]

i aint got a good vent system i could take one side off though :\ the other side is attached to my mobo i take tht off i take my compo to bits heheid be happy with 2.6 for teh mo 2.8 wud b great but do i have to use any conductor stuff and tht ive read sumwhere that you need conducter stuff i dunno neva tried to overclock befor my im allready at 133 fbs because somehow my settings changed to 200 and i couldnt boot at all :\

what bout overclicking a gfx card?? i got a utility with my card to do tht its a geforce 4 MX 420, 64 MB SDR made by leadtek

[Dragona]

oh yea crucial ram forgot that my ram is made by crucial

[batboy]

Ok, sounds like we have enough info to start overclocking. It's hard to tell how high you should go before needing more cooling. The best thing to do is try a little bit and then check temps to see how you're doing. You might consider raising the FSB to 110 MHz (24X110=2640 or 2.64 gig). This should be an easy O/C. Set the PCI/AGP to default (33/66) and let it rip. The PC2100 RAM is a little slower than most of are currently running, but should be ok for this rig for the time being and certainly Crucial is better than generic. If this O/C works ok, run a program that stresses the system a bit and see if it's stable and check load CPU and system temps. If all goes well, you probably can go up higher, especially if you add another case fan. Leaving the one side panel off will help if you have poor case ventilation. Rearranging cables so they aren't blocking air flow will help too. Good luck.

hi

my fsb was set to 127 allready ... 3.1 GHz :O v core was 1.50 ave and temp was 43 - 45 Deg

ive set fsb to 117 or 118 so it just hits 2.8 GHz it was warming up to about 40 wen i checked in bios but i dunno how to check thru windows :\

[batboy]

Oh, well sounds like you're an overclocking pro now. There should be a monitoring program that came on the install CD to check temps in windows. If not, download MBM5.

[Dragona]

i downloaded it but the cpu temp only shows up as like

10oC - 24oC

i think its reading wrong its runnin at 2810 MHz

[Dragona]

ive got a 2.4 running at 3.2 min temp 32 oC Max temo 52 oC is it running ok or u think my temps are inaccurate?

[hannas]

My 2.4C is @ 3.28 and i get temps between 30°C (idle) and 40°C (full load). I am on air but with a zalman cnps7000A-Cu so that helps things come down by about 12-15°C in my rig.

If you are on stock cooling then those temps seem to be fairly accurate - what is your core voltage (Vcore) BTW? - the more Vcore, the greater your temps will be and the more stable your oc at high clockspeeds...BUT the more extensive your cooling rig needs to be. I wouldnt want to let the 52°C go much further than that, would be comforting to see it in the mid forties even - you might want to look into some better cooling - Check this out for ideas (www.zalmanusa.com)

Good luck with it all!
:|

PS If those are temps attained with a default Vcore, my advice is not to touch your vcore till you have some better cooling:)

Have a look around here for some great ideas and opinions on cooling (http://forum.oc-forums.com/vb/forumdisplay.php?s=&forumid=6) tell these guys what you have running and what you have to spend, what you require of the cooling ect and they will paint a good picture of what you are up for!

Happy oc'ing!!!

[Dragona]

they were with default v core but i have no additional cooling and 52 is like if i have legend of mir, ut2003,half life, and ut running all playing sorta i tried to make it use as much load as poss and thats the highest it went its usually around 48 with things i run daily . .UT 2003,Mirc msn, out look, ie,anti virus and all tht

thanks for helping but next thing on ma shoppin list is an operating system . . .unfortunatly windows :( thinking of gettin win 2k pro is that just for ppl running servers or can normal peeps use it without a network?

[Dragona]

if i have oc'd this far would like using a printer crash the compo because its unstable? it keeps happening but i think it did it a few times before i did the OC

[batboy]

Dragona, that's looking good. Nice overclock! Low 50's load CPU temps with stock cooling is not bad. It's nice that you were able to do that with default voltage. Sounds like you got lucky. I use Win2k Pro on my home system and I love it. It's not just for servers. Does your printer use USB? I'm working an a friend's computer that locks up when using an USB HP printer. Not sure what the problem is with it. I doubt it's because of the overclock, but set your system back to default and see if you still have the same trouble.

[Dragona]

thanks for da cgood comments :D and yea the printer uses USB its a lexmark z12 and it will work fine aslong as i dont like do anythuing untill job has completed so i cant go and look at web pages oor anything it will just ike tunr screen onto standby i found out how to wake it up from that though only enter will wake the monitor up, but it will go black and then freeze completely i think the black screen is my new GFX card that i got few weeks bk i will probs just update them later on but last night it took me like 2 hours to print off 6 web pages because of constant crashes. then it stops internet activity aswell my modem has always been tempremental though one slight change and it wont work for a while. thanks for everyones help trying to oc my gfx card now though will try wen i get a few case fans.

[batboy]

Maybe try turning off the suspend mode in the power management section of the control panel.

Hi,

Can I ask why is this needed? What could happen if not set to default?

Thanks.

[batboy]

If the PCI bus is too far out of spec, this can cause instability. Since the IDE controller is ran off the PCI bus, you can have harddrive data corruption too. The default PCI bus speed is 33 MHz. Usually once you get above 37 MHz, you can start having problems.

[Dragona]

i cant change those settings it just skipped passes them like it skipped passes the 24X which is the multiplyer it was like grayed out so guess they dont want me messing

[asw7576]

Dragona: Have you try 133FSB x 24 = 3.2Ghz ? who knows you got lucky. Celeron is good overclocker. Just try with 1.65V and cross your finger.

Mine is Celeron 2.0A @ 3.3GHz @ 1.65V (vid pin mod).

He already has it running at 3.2 gig.

Dragona, try turning off the suspend mode in the control panel within Windows.

[Dragona]

i have done am gonner try [rinting laterz

[Lancelot]

I built a video rendering box for my bro-in-law based on a Celly 2.4 on a Asus P4PE board and it ran 3.2Ghz 533FSB the first try. We set Vcore to 1.55V just to be sure and it ran Prime95 overnight just like that, lol! It's one of the easiest OCs I've ever done. That box has been rendering DVD/DivX/AVI files and capturing firewire video off a DV camera, and has been stable ever since...

ooops.... sorry, my eyes need repair.

try 145fsb?

Your mobo is asus p4s8x-x? I have this economy mobo too. I matched it with P4 1.8A @ 2700 @ 1.650V with PC3200 @450 MHz DDR. Very satisfied with this setup despite many people have very bad experience with early p4s8x ( without another x ).

This mobo don't have pci/agp lock, so fsb over 150 is luck of draw.

[batboy]

His first post said he had an Asustek P4xp-X. When I looked it up, it appeared that 133 FSB was max.

[Dragona]

looks likeure eyes still need a slight repair its all in meh siggy

Intel Celeron 2.4Ghz @ 3.2GHz, 512 DDR, Geforce 4 MX 64 MB SDR, Asustek p4xp-x mobo, Western Digital Caviar 120 GB 7200 rpm 8MB Cache,

see hehe 133 fsb is my max plus im gonne turn it down to 3.1 untill i get an aditional fan . . .is it better to have like a second fan over heatsink or is it good to like have 3 case fans? or summat like that?

[batboy]

I like having a case fan in the back near the CPU exhausting hot air out of the case and at least one case fan in the front pulling fresh air into the case. Rearranging cables and routing them out of the way often improves ventilation. As long as your CPU load temps don't exceed mid-50's, you're ok.

Thanks Batboy.

I didn't know these.
