My Pentium 4 Northwood doesn't like to be overclocked. I once managed a fsb of 110 on default voltage, but it wont even do that anymore. I cannot oc to anything, no matter the voltage (I haven't tried 1.8v due to heat). It either won't post or won't completely load Windows. Shouldn't I be able to achieve at least a moderate overclock with my hardware?

Try it with only your Samsung RAM in slot 2. Also, make sure your video card is running at stock speeds.

could mis-matching RAM cause instability ( i know it could, im just making the point.)

also, with all that hardware, what power supply are you using? is it a name brand?

The power supply is an Antec 400W (NOT a dual-fan truepower). The graphics card is running at stock. Before I installed the SAMSUNG ram, I could only get up to 2200MHz. Now I can't OC at all.

What are your ram settings? You may need to increase the latency to hit higher clocks. Try CAS 2.5.

Been there done that. I've tried the highest latencies to no avail.

What is the best core to overclock my p3 1ghz is a coppermine , i can only get a 80 mhz over clock I WHANT MORE im using jumper setting switches on my mobo to do it XOOXOX

uh....

If you guys wanna overclock TRY USING AMD!!!!

xp1600 runnning around 1833Mhz...(xp2100)

Take out all your peripheral cards except for your AGP, and try overclocking again; maybe one of your cards is the weakest link...and I've never heard of Microsoft network cards...that'd be the first one to go, if you were asking me.

Also, like BA said, overclocking stresses any weak links in your system, and having more than one RAM chip adds one more point of failure. It's always best to use only a single chip when overclocking.

Can you change the CPU/MEM ratio for your mobo? Sometimes playing with that will allow you to get a better overclock (or it can result in a system that won't boot, so you'd just change it back again).

I have a similar problem. I can only get my 2.0A northie to 2.46. I changed to multiplier to 123 (or 126 i cant remember), and thats as high as i can go. I got it up to 2.46 with the temperature staying at an even 25 degrees C (which i thought was strange). I can go to like 2.52, but it wont let me get into windows it i do.

I dont thing it is the cooling factor, because as i said, its running at about 23-26 degrees all the time, the highest i got it up to was 37 one day, because i was playing UT2003 for like 3 hours.

Is it perhaps a windows problem?
or a hardware problem?

specs:

Aopen AX4B Pro-533 (int NIC)
Intel P4 2.0A @2.46 (With regular old Coolermaster P4 fan)
512 MB DDR2700
WD 80GB 7200 RPM ATA 100
GeForce 3 Ti200 128MB DDR (mem 215/gpu 475)
Sound Blaster Live! XGamer
Lite-on 24x12x40x
Sony 16x DVD-Rom
Mitsumi floppy
Windows 2000 Pro & Windows XP Pro (Dual booted)
(I also have two 80mm case fans in the front, one in the back, and one on the side panel).

I notice you're using an AOpen mobo, Ran Dum Usa. I had that same board at work, and for some fun, I thought I'd see if it'd overclock a Northwood. I didn't spend hours at it, but I couldn't get that bastard to boot with anything but the default settings. Overclocking should take work...but not THAT much work. All one really needs to do with a decent mobo is crank up the FSB to 133, and it should boot just fine. Anything above 133 is where the real overclock lies.

I barely even increased my voltage on my Asus P4S533/1.6a, and it boots and runs just great (even after several hours of online UT2003) @ 2.45. Could be mobo-specific. AOpen isn't known as a kickass enthusiast motherboard, sorry to say. Your problems aren't because of cooling.

Thraxx - that opinion is quite uninformed.

Intel has been the top of the overclocking heap (by a significant margin) for the past 6-8 months (since the advent of the Northwood core).

Don't get me wrong, I like (and use) AMD. But to say they oc better at this point in time is pretty naive!

You are getting a great oc on that XP 1600+! Mind telling me your settings and how you got it cooled?

Yeah thats almost "TOO" great wink wink hint hint. Needing to see some facts on that one. Older generation AthlonXP was not great at Overclocking. I can get about 230MHZ on Air and close to 280 MHZ on water. Your claiming much much more than that.

The biggest air-cooled overclock I ever got on ANY AMD processor was just over 200 MHz. My Duron 800 hit 1060, but ran best at 980. My current 1.2 T-bird runs at 1425 MHz with the best damn HSF you can buy, and the best internal airflow you could ask for...short of watercooling. I'd really agree with D-W; I'll have to see proof of any air-cooled AMD getting 300+ MHz overclock...

With P4's, you can break that margin easily. With stock cooling, no less. And with GOOD cooling...you might get close to an extra gigahertz!

LOL......you all should have seen that post before I decided I was being too harsh and decided to edit it.

LOL Putwig, be like me, and be harsh anyway! Unless it's a politically correct, slanderous, or racist remark, shoot from the hip! Tell it like you see it! (But be prepared to face consequences if you oops.)

I put my ass on the line every time I do a rant, and so far, I've only eaten crow a few times. Lucky me; crow doesn't taste anything like muff...

Well, there's always the possibility of the chip not being a northwoods...but that depends when you got it. I know these willamette chips can't get very far on overclocking, and a lot depends on whether your motherboard can do it or not. I know I can only hit 109x18 FSB on my 1.8 and even then the onboard sound screws up in a lack of electricity. Hey, for all you know it could be a bit of overheating from a lack of cooler air coming in for that CPU heatsink to work well.

yeah I have trouble with overclocking. With my new 2.4 all i can get is 105X24. Anymore and it will not post.maybe it is my mobo or maybe my ram.Ohh well.

It IS a Northwood. (512KB cache, 1.5 volts, .13 microns)

Damn, that's bad luck guys! Did you skip the incremental increases and gun for 133? Perhaps it won't boot at 109, but it might at 133...just a thought. I had no problems boosting the 1.6a all the way to 153 x 16. But I do recall reading that the newer Northies are less overclockable...but still very overclockable compared to AMD chips...I mean, I've seen 3.6 GHz screenshots from late-model P4's...
