Why can't I overclock this P4????

[Icewind]

This is beyond fustrating!!!! Actually more, it just infuriates me!
I spend alot of my hard earned money on top notch components that I spent hours researching into. My components consist of a Intel p4 2.8C, ASUS PC4800-Delux, and Kingston HyperX 3500. I build the system from scratch and it works splendid, but the second I go to change even the CAS Latency the system starts to freak out on me! I went to change the RAS to LAS from I think 6 to 2, and the system just hangs after I try to reboot it. WTF? This Kingston HyperX is the best around, what the hell is the problem?

Then I just tried rasing the FSB I believe it was to just 205...nope, my system just hangs there with a black screen!! GOD THIS IS SO FUSTRATING!! Everyone else has this easy going luck OC P4's and I can't even change my damn RAM settings without a crash!! What am I doing wrong?? Please guys, now I really need your expertise...I really need the help this time

Now i know you know that overclocking is luck of the draw and not always guranteed...

BUT! I would think that little 2.8c has some juice left in it..

Just to see, have you ran memtest86 to check and see if your memory is acceptable?

 

[Icewind]

Have no idea what that is..

 

[bjc112]

memtest86 is a program to test if memory has errors (BAD ram)...

All you do is load it to a floppy and Reboot...


Google is the $hit

 

[asadovsky]

Springdale/canterwood chipsets don't like the lowest RAM timings. Try setting your RAM to 2/2/3/6 (3 being RAS to CAS) and see if you can overclock then. Also keep in mind that once you start raising the FSB speed, you will have to raise the timings some more. You should check Kingston's web site to see what timings they recommend, but really, it's mostly trial-and-error. Make sure you use memtest86 to test the RAM, and turn off legacy USB support in the BIOS.

Hmm, don't have a floppy in my computer, I eradicated it years ago.

So how how in the hell are these OC the systems with these low end timings then? I did a Sandra benchmark on my memory, and it around the mid 4000's. How can I get mine to that 6 gig range that i've seen from other guys? Whats USB legacy support?

 

[butch84]

if you dont have a floppy, you can download an iso of a bootable cd from the memtest86 website. all you hafta do is boot from cd and you are set.

Humm... How old is the motherboard? Some motherboards have jumper settings to protect you from overclocking. If removed or set wrong you may be more likely to fry your CPU! Good Luck! read the manual over good!

he has a ASUS PC4800-Delux, a new mobo practically built for OCing

I see... Looks like I can't help you after all! Sorry!

From what I know, USB legacy support just allows USB support in DOS. It also makes memtest86 not work right.

I don't know what you mean by "the systems with these low end timings" or "that 6 gig range." Be more descriptive and we can probably help you out.

 

[asadovsky]

Also make sure you have turbo mode off (set to standard). If you had it on turbo mode that would explain all your problems.

 

[Icewind]

I've seen guys with there Sandra Benchmarks that are in the 6 gig range for the memory test.


I completley watched that Corsair memory demo, and I took notes and listend to parts over and over so now I know what all the timings are and mean (finally)

I guess what im confused on is why my system would crash just by me changing the FSB to just 205. Should I change that ratio thing, which im still kinda confused on.

Also, Think my Kingston memory can go beyond its specced 434mhz? Will upping the voltage hurt it? I know your not supposed to if you can avoid it

 

[OC-Freak]

Set memory voltage to 2,75V Try first 2,5-3-3-7 memory timings And set all performance settings to auto instead of turbo.

Then overclock and se how far you'll come.

Personally I'll give a P4C voltages up to 1,65 volts...but not more. start with 1,55V and oc and then feed it with more and more up to 1,65V and see if that helps.

When you've found a stable OC then try to lower memory timings and such...

Also update your bios if you have not done so (I'm running 1009 beta 6 which seems to be VERY stable).

Edit:
What CPU cooler do you have? Get a good one like the thermalright SLK900 with a 92mm fan.

And what multiplier are you using with the overclocked FSB?

What exactly does the turbo mode do?

I just got my 2.4c in a p4p800 mobo up and running last night @3.2ghz. But I noticed that whenever i enable turbo mode, I can't get post even on default settings.

Im using a Zalman 7000cu


This HyperX is totall crap. It just decides outa the blue to work for awhile, then crash.

And im deftly afraid to update the BIOS, so afraid my computer won't work afterwards...

 

[Dagger1011]

You have nothing to worry if your mobo is still under warranty. But eventhough its not, updating the bios is relatively easy. Just follow the directions from the asus website carefully. Frankly, that's the first thing I did as soon as I got my mobo since I do not wish to encounter the problems that has already been fixed. Its the experience that gives you the thrills you know.

 

[Icewind]

Browing through Corsairs website, people are indicating the 1009 version kills system performance for some reason. I'll just leave mine at 1007.

Nah, Hyper X is decent...

I have some PC 3200 running a 220 FSB stable 2/3/3/6

There are lots of intricate details to overclocking. You can't just change anything you want. It all plays a big picture. You are doing the right thing in the forums, but approaching the problem when you are that frustrated usually makes for worse decisions and bad judgement. I can give you my latest results from Saturday to compare... I have a similiar setup, only you have better processor, and memory... Watch your temperatures for CPU and memory, and double check your voltage readouts at least in the BIOS. Move up a little at a time. Try to move only one setting at a time. You will never figure it out just moving everything at once. Well you will, but will take you lots longer. Once you own the components for a little while and are familiar with what they can do, it gets easier to overclock the next time. Memory is finicky on 875P boards, because some much rides on the memory to maintain the DUAL channel operation correctly. Don't push them too far. It's not like 4000 in memory bandwidth isnt faster than most motherboards in the first place. It'll all come together... Look at my tries... 34 systematic attempts just to find best config for me....

I shoulda just taken the chance and gotten the Corsair, now its to late. Googlegear doesn't even carry sets of TwinX. Whata useless website...

Thanks for a very helpful post. I've got an msi 875P board. It's been nothing but a piece of $hit. I can't even get the sata drives to be recognized anymore. I installed Xp on an ide drive, but I want to install it on a raid setup. I had to get corsair 3200 mem to get itto boot up. I love my Northbridge 1.6a @ 2.12ghz. After reading your post I guess I've just got to bepatient until I get things right,

Update: Patience paid off. Alles ist in ordnung! XP installed on the 2 raptors (RAID 0)!
