some people said my voltage too high
is there anyway to hit 4.0Ghz for my processor?

3.8ghz is running very very smooth.

but when i set 4.0ghz i can't even boots into windows
need expert help

No case fans?!

Well heat is deffinately a problem then!!

That is way too much mate, and 1.5V on a 45nm chip won't do much good

 

[ov2rey]

hmm.. but if i overclock to 4.0ghz i will add fan

this is my cooler

then what voltage should i set in the bios?

thanks for ur reply guys ^^

 

[FilipM]

1.3625V is considered as max safe by Intel, thats under load. So I would guess 1.39, 1.4V in bios. Max safe temp is 72.4C degrees, while the thermal junction is at 100C deg (cpu throttles down). I would keep below 65 deg at max load.

Add a fan anyways, you will get more stability without in creasing voltage due to lower temprature.


BTW, Fill in your system specs in UserCP

okie thanks i will lower down the voltage


but is there anyway i able to hit 4.0ghz?

 

[FilipM]

I don't know, it's all trial and error. Get a fan first. There is a way to hit 4.0Ghz If you hit 3.8Ghz in passive, you should hit 4.0Ghz with active cooling, but with what voltage, i dont know

 

[InnocentCriminal]

:O

Ever heard of static electricity?

 

[Hayder_Master]

what is your cpu VID

 

[ov2rey]

what is your cpu VID

sorry i'm new member

what is cpu vid?

i just fill up my system specs in UserCP

Yep, that aswell hehe, he should put it on non carpet clothing sutff

 

[Tatty_Two]

Please add your system specs and get some decent cooling in there BEFORE you even try putting that kind of voltage through the chip. Are you trying to get to 4gig for benching only in short bursts? Many motherboards wont take 500mhz on a quad in any case, many P45 chipset boards will though, hence why I said to add your specs!

a.. i have 3rd party heat sink, u can see it from 4th post from this thread at the above

It's great, but, the heat is just sitting on it. The air around it is getting hotter. You need air blowing over it to keep it cool. The heatsink alone isn't enough when you're making that much heat.

What are you monitoring your temps with? Use Realtemp and report back after you dial it in (Read the Realtemp section)

Also that voltage is WAY to high... my 9450 will do 3.8Ghz @ 1.3 Vcore.... Also you have probobly severly degraded the life of that chip, if you have run it for any length of time @ load with that kind of vcore. Anything over 1.45 is severly dangerouse on a 45nm chip.... more so at those temps.

Is the motherboard a P45 chipset?

Read into GTL refrence voltages, as you will need to tweek those to get it stable at those clocks, also note that you will need a fairly high vFSB voltage to hold that high a FSB stable, i needed 1.4vFSB to even post into windows @ 500FSB on mine. I would start there and work around a bit (again each cpu/motherboard is diffrent) Also those voltages are well out of spec so any kind of reliability as well as logevity can be seriousely compromised. Though based on the voltage you have already stuffed into that thing i dont think this will be an issue.

You will also probobly need to bump the vNB up into the 1.3-1.5v range, as these Quads are hell on them.

My Q9450 runs 3.8 great but is flakey at 4.0. I'm too much of a wuss to try 1.5VCore but I'm sure my board and ram can handle it.

 

[Carrion]

1.55V!? I'm at 1.45v, 4GHz on my Q9550, Prime95 stable.

 

[NinkobEi]

do any of the quad core 775 chips run @ 4gz w/ lower volts? I want to pick one up eventually to replace my c2d, but wouldnt feel comfortable with such high temps.

What motherboard? Could be the beginning of an FSB hole, also not many quads will do 500FSB.

Thats pretty high vcore :S

What alot of people dont understand is the 45nm quads dont NEED alot o vcore for high clocks, they need alot of vFSB, as well as higher vNB. Also the temps in this thread are much to high do to having NO fans. IMO my 9450 @ 1.4Vcore loaded @ 3.8Ghz doesent break 60*C and thats with synthetic tests too, everyday use is mid40's to low 50s.

Also anything over 1.4vcore on a 45nm quad for any ammount of time is asking for trouble, they just cant handle it.

i have lower down the voltage to 1.38v for 3.8Ghz

You may need 1.4V+ to get 3.8GHz stable in Prime95.

Can you fill in your current voltages, and FSb settings?

And is there only one adjustment for CPu reference?

also the CPU termination voltafe is the vFSB, my 9450 @ 3.8Ghz likes 1.24, though you need to adjust the GTL Refs when you change the vFSB as well, that would be your CPU Reference.... start @ 0.620 for the CPu Ref, and work up one notch at a time up to the 0.670 mark and see if you can increase/gain stability that way... once you find the magical number work out the target vFSB and keep that number in mind as you change the vFSB. for example set 1.24 vFSB and 0.620 CPU Ref that will give you 0.7688 target (1.24*0.62 or basically 62% of 1.24) now if you are stable at the following settings you will know your motherboard/CPU like the 0.7688 target, and as you increase the vFSB you modify the CPU Ref to keep the target at or as close to 0.7688 as you can.

.... I hope that makes sence... it makes sence to me... and thats the basics behind GTL refs, you just need to tweek untill you find that golden number (its diffrent on all motherboards/cpus) once you find it though your quad will do amazing things. like 500FSB on air
