Hi ya'll

I would appreciate it if someone good point me in the right direction.
Im new at this and i just build me a new pc and am ready to boost some more power outta it.(system details u can read below).

When i finished building it the system was very unstable but i finally got it running good, my ddr2 memory should have been running at 600Mhz and fsb at 800 so the setting should be 3:4 but the gigabyte mainboard i had was at 2:3 (533-800) therefore my system halted very often, but luckely i fixed that with help from kingston.

My old pc was a P4 2,4 and when i converted a movie from avi to dvd it took 1,5 hrs (100% processor usage) my new system is slightly faster but i notice the processor is only used for 55% is there a reason for this, maybe the hyperthreating ? i use vso to divx

anyway i want to overclock it now a bit even thinking of getting watercooling, the smartfan is driving me crazy with the noiselevel (i have a lianli case)

My system doenst need to go critical overclock but a bit faster would be nice. Do i have to use the gigabyte bios overclocking tools or maybe the software from gigabyte (tune-up 5 or something)
Or is there another method ?

wich would be best for me ?

any help would be very much appreciated, thnx in advance

marty !

My current system :

Gigabyte mainboard GA-8N SLI Pro
Intel P4 650 HT (3,4 GHz 800FSB 2MB)
2048 DDR2 Kingston @600 Mhz
2* MSI GeForce 6800GS 256MB PCI-E SLI
1* 200GB SataII HDD operating winxp pro sp2
2* 250GB SataII HDD in Raid (500 Gb data)
500W powersupply
Lian-Li big tower
 
why don't you just try nudging the FSB (clock speed) in the BIOS up a little bit?

I have a 3.0Ghz P4 overclocked to 3.24Ghz atm, not stable at 3.48Ghz due to RAM... I just changed the CPU clock speed in the BIOS, (which is the FSB).

I ripped a 80 min CD to MP3 format in about 2 minutes and 15 seconds.
 
The BIOS is the best way to OC that rig. Go in and start taking it up one step at a time.

tx for the advice, ill play with the settings a bit.

is there a guide for this way to oc ?
there are so many settings, i saw increasing voltage of cpu, ddr memory and fsb.
also i can set the mainboard to crusing, sports and even turbo (there are 5 settings there)
and a couple of other things i can change, dont know exactly what they mean and the manual isnt very clear on that either

cheers !
 
Your MB is similar to mine in that it has some pre-configured overclocking schemes. These mostly work well and will normally give you a mild to aggressive overclock. Try their pre configured only after writing down your current settings. Especially since you had to make changes to timings for the memory to work.

I would then run a Sys burn app of your choice to make sure it remains stable. With the preconfig tuning you may have to still apply your current memory settings as it may try to reduce them from where they are currently.
 
Luminaris,

You are right in saying that changing the multiplier is easy. I was just suggesting he try a mild overclock using the preconfig so he could see what changes they make for a factory overclock. If it is at all like the MSI Neo2-FISR the preconfig overclock is just as easy as changing the multiplier.

Just another way to go about it. Why not try what should be a somewhat safe OC straight from the factory?
 
That's true and a rather convenient way to OC however, even though the board has factory settings, you have to keep in mind everything else attached to that board. You take too many steps all at once, the machine may not boot. Even though the board may have protection, hardware still may get damaged. Its always a good idea regardless IMO to just take things one step at a time, test and check for stability.

You can do what you want, I've seen absolutely disastrous results over the years from jumping the gun.
 
Good points,

I understand what ya are sayin. I agree too. But if someone is a newb at overclock procedures and they have a board with the preconf it may be a little bit helpful too.

Most of the boards with the preconf OC are pretty well prtected against the type of cat failures you are talking about. For instance the MSI board I have will allow for Preconf but tells you in the manual to NOT use the turbo mode unless you know exactly what you are doing. Many have the safeguards built in. Like you said if he is unable to boot just back it off.

I like your one step approach too. But many people have NO idea what a FSB is and how to overclock it 🙂
 
Your absolutely right about people not knowing how to overclock. They tend to get rather impatient too. I've learned alot of things and made alot of mistakes but the one thing I've learned from all the good overclockers is, one step at a time. 😀
 
Actually it is a 12 step program 🙂

Hello my name is Luminaris and I am a Chronic Overcolocker (crowd responds "Hello Luminaris") :lol:
 
Everybody thank a lot for all the replies, ill go step by step tonight and see how my hardware responds to the preconfig oc setting on my mb.

I guess i have to check how my system is doing with eg the prg CPU-Z,
i can check the fsb speed, and my cpu speed, right ?
And with the software form gigabyte i can monitor my cpu temp, that is important not to let it get to high when the cpu gets stressed at high speeds.

What about the 50% of cpu usage will that go away or is it that software that only uses 50% and when oc-d it just goes faster with the same 50%

anyway ill let u know and again thanks for the responses
 
regarding the 50%. That is caused by use of HTT. HTT splits up the processor into two virtual cores... however, it is only taken advantage of if you have two threads running simultaneously. Most software doesn't do that. However, in benchmarking, and in every day life, it runs much faster with HTT on, even though it only uses 50%... :)
 
thnks windshear !

i tried to boost up the mainboard through bios pre installed setting but my system didnt even boot up.... had the setting on the 2nd slowest (of 5 choises > sports its called and turned on turbo fsb) but it wasnt good for me...

is there a guide about my mainboard in combination with my processor and ddr memory ? if im about to change power settings and stuff i better knwo what im doing...

cheers !
 
The best thing to do is just leave all settings in "normal" mode and just take the multiplier up one step at a time.

More than likely, adjusting it to turbo mode had some sort of negative effect.

I know with my DFI, I found it best to just change the memory settings to manual and leave the timing in auto mode to get things cranked up. Once I got the CPU up high enough and was still very stable, that's where I started messing with RAM timings.
 
and Luminaris... I hope you're talking about the FSB.... not the FSB multiplier, when you refer to the "multiplier"... at times, your posts confuse even me! 8O
 
thnx for the advice but no luck.

even if i do a 3dmark cpu test my system halts sometimes even when my settings are to normal as they should be for this prosessor.

When i boost up the fsb my system becomes more instable, do i have to boost up the ddr2 equally ?

settings are now 800 for the fsb
and the ddr2 is now at 600
I also ttried 848 and 636 (my cpu was at 3,6 instead of 3,4) but soon my system halted.

Is it possible that my system can get to hot even if it isnt overclocked (800/600) i have a big lian-li case and standerd coolers.

Ive read somewhere that my processor best is overclocked if i lower the multiplier from 17 to 14 and than raise the fsb.
Problem is in my bios i cant lower the multiplier, only change the fsb and ddr2.

I think i can best concentrate of first getting my system stable before overclocking, any ideas how i best check my settings ?
I also read that my pent 4 650 has a problem with leak power if overclocked, grr just my luck
