Hello everyone,

I've got a bit of a problem. Whenever i try to OC my CPU, it always crashes. Its a 3.0ghz Prescott CPU (system specs under my name) and has a Gigabyte G-Power PRO cooler on it.

I can get to 3.6 and 3.8 Ghz via my motherboard utility, but once i minimize the mobo utility, within 1-2 minutes, i get a BSOD, even at 3.5-3.6ghz. I checked the temps at 3.8 (barly had any time) and the CPU temp didnt go over 30*C (i turned the cooler on max, 3200 RPM).

Whenever i try to OC the comp in BIOS, the comp sometimes just doesnt start. If i go to 3.6 or 3.8 (FSB from 200 to about 230-240) it sometimes wont pass the initial 'beep' of the computer, or will freeze just before the welcome screen. I have also tried using all of the different CPU:RAM ratio's (dont know whats what), and it still doesnt work.

Lol, i bought the cooler so i can OC my comp, and now it won't OC at all :(...i thought i could at least get it to a 4Ghz :p...so all help is greatly appreciated :)

Cheers :toast:

It's probally your ram
 
What about the ram?

Btw, thanks for the really quick response :p
 
Cj has an excellent point, but there is others...

Sometimes, when you do O/C's?

You have to mess with Front-Side bus & RAM "timings" (often lessening them/making them "worse") AND up certain voltages on the CPU &/or RAM.

:)

* It's a PAIN/HASSLE, imo... but, if you hit it "right"? You get those gains...

(I'm "lucky" in 1 regard here w/ the mobo I use - it has BIOS based "presets" for this type of thing, & that's all I use -> 3% overdriven CPU, but THAT IS IT!)

APK

P.S.=> The guys here are way, WAY into that area... hopefully, you'll find one w/ your EXACT cpu & if lucky, mobo too, & let them "guide you" thru doing it right/to-the-max... apk
 
its not ur ram... u need to up the cpu voltage and the vdimm voltage and then raise the fsb via bios, if that doesnt work get a newer version of bios... there is no way on this purple earth that u can reach 4 ghz with a gigabyte cooler...:ohwell:
edit: i see the master of the books is here
i have ur cpu so i can help u with understanding the max volts it can take...
it can take around 1.6-1.65 volts... it will heat up alot so trash the gigabyte and get a thermaltake
if u do, u should beable to reach 4.3-4.4 ghz on the thermaltake... the mobo is very good for overclocking, just dont use the software utility, use the bios instead.
 
I wanna get a permanent OC on my comp, something that will always remain stable (thats why i got the cooler for the CPU).
 
if u want permanent overclock then u have to use bios... read my post before... i edited
 
i take it you increase the volts in bios as well? (lol as you can see im a total noob wen it comes to OCing a CPU :p)
 
You are very wrong RPG, as always. Not everythig is about the voltage (Talking about a couple posts up #5(berfore he edited))... he only has pc3200 ram mr. "7800rpm hdd" so it's not that, it's that his rarm is too bad, Pinchy, I suggest you loosen up your timings a tad and put the divider on "133mhz" I think it is... it depends on your motherboard... now after that try to clock your cpu high.. once you start crashing, you know it's because of your CPU, raise your Vcore voltage a little until you get it stable, after that you know your CPU is stable at that speed, try changing the divider to I 1:2 and you should not crash, if it does then raise the Vdimm voltage slightly or loosen up your timings more until it's stable again, but sometimes loose timings is a bad thing. There are articles that explains what RAM timings are and how to work with them. Goodluck man. You can get permanent overclocks in Windows as well as long as the program loads up the profile after you boot up. But usually people use the BIOS.
 
its.... not... his... ram... im telling u, its his volts... i would no because i had the same problem because my cpu volts were too low, set to 1.55 and 1.6 and had a blast playing games without lockup... memory too, u should up the mem volts to like 2.9 or 2.8, or 3 volts depending on wat ur stock volts is
 
[beep] you should never raise your vcore that high.

Don't listen to rpg, he's just a postwhore. (He doesn't even own the system in his sys specs xD)

AHAHAHA it says he has a 102 oc on his ram.... yeah, right :laugh:

LOL! Assuming you mean ME... good one!

:)

Whew - here? I am no "master" by any means...

I only "cursorily" mess about w/ overclocks nowadays, but did a LOT a few years back & some of my "experiments"? Not a great deal of return, imo!

(But what I did get was better o/c's than most folks could & STABLE (key point imo on that latter note)).

E.G.-> A GeForce Ti4600 AGP mod I did years ago (lol, note the copper CPU cooler I put into place, in lieu of the stock PUNY oem one):

APKGeForce4Ti4600128mbDDRAMAGPBottom1.jpg


APKGeForce4Ti4600128mbDDRAMAGPTop.jpg


A great deal of effort, little "ROI" (return on investment) imo when all was "said & done"...

Even though MOST of the parts I used I already had (old powersupply heatsinks, 486 ones for the RAM on the vidcard)...

It was more about the TIME I poured into that experiment...

E.G. #2 from that machine:

The CPU's that system had (Dual Pentium III 1ghz SMP on Abit VP-6 mobo) only went up to 1152mhz (8,000 rpm/52 cfm airflow capacity Delta fans (LOUD), copper spacers, artic silver 4, & pure copper heatsinks)).

Not a "LOAD" of return, but what I got was stable...

(P3's (std. ones) weren't GOOD o/c'able CPU's I found out!)

Sounds like you are 1 of the folks he should reference, by all means, since you have a similar setup & for certain, same CPU... almost best possible reference he can get imo.

* YOU are the "master of books" here on this one imo, but not just books - but instead, "hands-on/University of Life" experience (best there is imo)...

Dude, a socket 478 can not hit that high unless u have insane cooling. Same thing with 775, The silicon on those chips (The 3 Ghz ones) are crap.

DO NOT RAISE YOUR VCORE UP TO 1.6 NOT EVEN 1.5425!
 
Ok i just switched comps so i can OC the one i was just on.

Ill try both methods (ill start with the voltage only because it is quicker) and tell you which works :p
 
wow by the way you said that, it sounds like im gonna blow it up :s...

dude, he has a 775 and i have that same thing... used to have that same mobo too, but diff build... 2ghz p4 lol... u cant be talking... the chips are one of the best overclockers u can find... im getting my mobo back from rma in 5 days and will post cpu-z if it works...
 
Dont raise it over 1.6 from experience.....
 
I swear man, raising the voltage that high on a prescott WILL burn it out... HE HAS A 478 RPG

I burnt my prescott out by raising the voltage too high.... a long long time ago
 
it WONT burn it out because mine didnt burn out yet...
 
i have 478 not 775 :s
 
same thing... just then dont raise voltage over 1.55
 
RPG IT DAMAGES IT ALOT... IT MIGHT NOT SHOW AT FIRST BUT IT DOES!!! Pinchy, please do not listen to rpg


Rpg, you are a [beep] man........

Pinchy get me on msn bikr692002@yahoo.com

LOL well im in BIOS and i dont even know how to increase the voltage :p

Just another thing, i dont want to cause damage to my CPU cus if it dies, i got no money to replace it :p...so id rather go safe then sorry

BTW thanks for all the quick responses...
