Overclocking my Intel 2.8

I know, I know... the Presscot likes to get warm but...

...when I'm overclocking my processor?ABIT AS8 motherboard, by the way?how often should I up the voltage to the processor for every MHz I increase? I mean, I know the processor should be getting some extra power for the more MHz you increase it. Right now, it's at 3010MHz (14x215 @ 1.3375V). Is that "safe"? The original question might seem a little confusing... sorry :/ My main goal is to get this puppy as high as it can go without ruining it. I figure you guys know what you are talking about.

Thanks in advance!

Edit...:

I forgot to add that the only way I tested the stability of the overclock was using SiSoft Sandra's Burn-In wizard. I honestly don't know how well that tests stability but, again, any suggestions are appreciated.
 
First make sure your mem divider is set low, so you are only testing the CPU. Then, each time you bump up the clock speed, run prime95 for a bit. If that fails, bump up the voltage a bit, try again. Don't just bump it up every time you raise the clock speed.

Don't know the max voltage though ...
 
u can deffinately go higher, I currently have my 2.8c 30 cap going at 3.8 on IC7 G max2 (using water though) I would say on air that chip has potential to go to 3.4 at 1.55 or 1.525v at 3.8 my voltage is only at 1.6. good luck with your o.c
 
i keep crashing it... i feel like i'm going to break something. of course abit has that nice on-the-fly software and it resets to stock clocks when something bad happens... i don't know. i probably didn't put my ram high enough. any suggestions? it's just crashing a lot. i am on air, too.
 
What memory and PSU are you using? My 2.8e ran at 3.5ghz with no trouble, on an Asus P4P800, I have a 3.4ghz prescott running at 3.91ghz on my Abit AS8. I would be sure it's not something else such as ram that is your limiter before pumping more voltage in to the CPU. The highest I would say to go is 1.525v, and only if you absolutly need to. What are you using to cool that chip?
 
wow, i'm gonna have to get me a job @ compusa so i can afford all the uber cool expensive equipment required to pump all that BS.:roll:

Sh*t man, I got a 2.8 to go to 8 Ghz (that's right eight) using liquid nitrogen cooling.

Yeah and your also the Queen of England. No kidding, better get the wading boots out because the BS is getting deep.

Your asking to fry the chip. I would not recommend going over 1.525v for daily use.

What ram are you using? Best advice is to up the Vdimm 2.85V and lossen the timings to 3-4-4-8, if that doesn't work try running it at 5/4.
 
Perhaps you should read a general guide about overclocking first and then come ask more specific questions. I dont mean to be rude but some background knowledge would make this process much easier for you.
 
your ram is rated at 2-2-2-5 up to 400mhz, so unless you are running a divider, your ram is also overclocked. You will either need to run the memory with a divider, or loosen your timings.

So that's what CrapUSSR is doing with my rebate money? They're buying BS to overclock processors.
 
Howdy. I've had my 2.8E Prescott for almost a year now and just recently installed water-cooling on and have the following temps @3.25ghz.
Idle: 39-41C
Load: 43-45C

The specs are the following:
ASUS P4P800-E Deluxe
ATI 9800Pro
Antec Sonata w/380watt PSU
3 HDs (including a raptor)
Audigy 2 ZS

I've been trying to overclock it to 3.5ghz stable but can't seem to get there. I've tried pushing the VCore up to 1.5-15875, loosening the timings, and locking the AGP clock, but to no avail.

Now I know that 380 is pushing it for the PSU, but I didn't notice the rails dipping much below spec, although I'm not particularly sure which rails are stressed during the overclocking process. The temps don't seem alarming either (45-50). The ram holds well at 1:1 at 225FSB, but forces me to loosen timings beyond that.

Any suggestions?
