Advice on OC (P4)?

[dinoshan]

Hi guys,
Could you help me with this pls? I had this cpu for 1.5mths and believe it has been burn in for overclocking. Do i still need to run the tests before doing it?

Another thing is, my chipset is running a little too hot, i can't touch it for long, would i kill my mb if i oc'ed?

And could you recommend me some timings and or methods for this?

My rig is
P4 2.6c
(celeron stock cooler,I dunno whether P4's ones are different)
Asus P4S800 rev.1
PC3200 512ram
FX5200
PSU 420W icute


Thanks for the help.

Don't overclock, your powersupply is too weak. You might blow your power supply right away if you up the voltage.

 

[ChipDeath]

He's only got a 5200... even a Generic 420W should have no problems running that rig.

If a little overclocking was going to overstress his PSU I'd expect the system to already be unstable. It's not going to demand 100W more or anything - 20 perhaps.

That said though, I'd still rather have a good Fortron or Enermax PSU for peace of mind...

is your computer a p4 2.6 or a celeron 2.6

if its a celeron 2.6, i havent heard of many people overclocking them.

i would suggest though if you do get into overclocking that you buy a new heatsink and fan, because intel chips run hot your gonna need something to keep your processor cool

What's a Celeron cooler doing on a 2.6C?

 

[dinoshan]

I had a celeron 2.4 oc'd to 3ghz previously, that's how i got the HS. Now i bought this P4 2.6c because my mobo supports northwood only. Also this proceesor is much cooler than the one in my office prescott E(3ghz 60deg. cel at bios), while mine only shows 35deg cel.My overclocked celeron was running at 50 deg cel at full load and 38 idle.

How to check whether the PSU is at full capacity?
Would a watt meter do the trick?

 

[dinoshan]

I'm upgrading to 9600 or 9800 in a couple of weeks. So i guess i've to factor that in, for the psu capacity.

 

[scottchen]

The problem with your power supply is that its peak power is 420watt, that only lasts about 30 seconds before your power supplies blows up. continious it's only about 280-300watts.

 

[dinoshan]

Geez, that sux. Isn't that misleading then, the way the advertise the wattage?
Can a psu really blow cos of high wattage?
Isn't there suppose to be fuses in there to prevent one?

I had my celeron overclocked to 3ghz, isn't northwood suppose to be cooler (so drawing less power)?

What if i overclock without increasing the voltage, just fsb alone?Would that affect the psu ?
Already cpuid shows voltage at 1.6v.

How about my chipset? will it handle overclocking since it's hot. My system is already a 1.5yrs old except for the cpu. I'm thinking of getting a hsf for the chipset, could you recommend me something good?

Thanks

I've blown a 420watt psu before, it was a raidmax, it killed my entire system that was connected to it(YES INCLUDING HDD AND OPTICAL DRIVES!), and it died from me raising vcore on my 2.4C from 1.475 to 1.65V.

 

[scottchen]

I'd recommend you getting a fortron power supply that's in the 400 range, Or a Seasonic in the 350watt range, Seasonic advertises continious power, not peak. A good power supply is always a good investement, since you'll be getting a 9800pro, i'd definently recommend an upgrade in your power.

 

[dinoshan]

Jesus, that's bad. Was there any warning before it happened?
Like smoke,bad smell or something? Did it happened immediately while you were booting? Just anxious.

 

[dinoshan]

Actually i was going to get like 9600pro or 9800. Which do you think is good?
How do i know whether the psu is peak or continous wattage?
I don't want a rip off when i get one.

 

[scottchen]

The power supply sparked, didn't catch on fire, no warning, just sparked, smoked, died.

 

[scottchen]

9800 is obviously superior if it has 256bit bandwidth. <A HREF="http://www.newegg.com/Product/Product.asp?Item=N82E16817151021" target="_new">This</A> power supply is incredibly good, 80% efficiency certified, i got a friend who's running a 6800, A64 2800+, 2 harddrives, off of this thing, and the air coming out of the back is cold.

ESAD

 

[dinoshan]

How about the chipset? I already have heatsink there. Should I just by the fan? Do they sell it like that anyway?

What would be the best cooling hsf for chipset? I dont' mind the noise, my house is near the road and it's already quite noisy....

I have 2 hard drives, and a tv tuner card. Will removing them make any difference on the psu?

I was thinking of disconnecting everything including my 5 80mm fans (4in and 1 out) excluding 2 from the psu - except MOBO,ram,and vga card to oc my processor. Will that blow the psu? Thanks for all the info.

Your PSU should be ok for a while yet. I have a 2.4c o/c to 3.0 GHZ using a Zalman 7000 al-cu cooler, with a Geforce 6600 GT, 2x HD's, 2x optical drives and a fan controller. That’s all being supplied on a Zalman 400 watt PSU and I have no problems with stability.

Has anyone tired overclocking the new dual core p4’s yet? Are they any good if your looking to overclock?

 

[scottchen]

Thre is a huge difference between the Zalman 400watt and the generic Icute 420watt, the Zalman 400watt is made by Fortron, and that the continious load is near 400watt, while icute labels peak, so its continious is around 280watt.

 

[scottchen]

Wusy BTW ESAD stands for EatShitAndDie!

 

[scottchen]

Well your fans drains very little from the power supply, harddrives/optical drives drains quite a bit when they're working hard, the TV tuner card drains next to none. I still wouldn't bother overclocking if i were you until i could get a good power supply in there.

 

[scottchen]

The dual core chips are hard to overclock, since it only tells you the temperature of the 1st core, and not the second, so it could be throttling itself and you don't know it. They're decent at overclocking, but you have to cool it, watercooling is REQUIRED for you to get anywhere. Stock cool gets an average of 200-300mhz overclock, on an Intel chip, that does shitall.

 

[JeanLuc]

It's been a while since I lasted posted around these forums. Do you still have a p4 2.4 o/c to 3.4 ghz? I remember you said is was cooled by a Thermalright copper cooler (can’t remember the model number) with a Vantec 92mm tornado fan. Do you still have the same setup?

 

[scottchen]

LOL i've changed like 10 computers since them. Now i'm on a cheap setup, Venice 3000+ overclocked by 50% to 2.7Ghz, watercooled, with 3 radiators
