Not Reconising Overclock PC help?

[a98pmalcolm]

Hay all looking for a shine on the subject.

 

Iv just overclocked my Intel Q9550 processors to 3.8GHz from 2.3GHz

 

In the bios is says the system is overclocked and the cpu frequency is 3.80GHz but when i load up windows (seems faster) and check the CPU speed with a few free programes on the net is says the cpu's are at 2.33GHz???

 

Bios says one thing and aplications say another?

 

Will it display overclocked speeds on the aplications? or the factory speed only?

 

Any advice would be great.... I suspect Scott will pop up with a post lol

[GlennK]

Did you use CPUz to check the bus, cpu and ram clocks?

[The-Plethora]

Yeah download cpuz and it will show what speed its running at and the multiplier.

It may be that intel speedstep is still on which runs the cpu at a lower speed when its not doing much.

[TonytotheB]

What is your mobo? If it has the auto Turbo that some ASUS' have, it may overclock only when needed. Post your other specs

 

And CPUz is awesome. Everest is another good app for temp monitoring for an overclock

 

BTW what cooling do you have for that serious overclock?

[Wez]

Another +1 for CPUz

[Scott]

Ask it nicely.

 

CPUz +8 here.

 

Although I would be cautious running that processor at that rate. Have you done supporting mods to the computer to handle it? If not it won't last long and will run extremely hot.

[shima60]

As well as running cpuz i run realtemp just to keep check on my cpu temps p.s watercooling is the way forward for overclocking that much.

[DamanC]

Its been fairly well covered already, but one question, where did you do the overclock? Im guessing because of the hike, in the BIOS?

 

Ensure Speedstep is disabled in the BIOS too.

 

Slap 'prime 95' on it and check the frequency then. You can monitor on the fly voltages in 'speedfan'

[a98pmalcolm]

Thanks for the replys.

 

My cooling will be fine as i use the Antec 900 case and iv customized some fans so its 4 inlet fans. And my CPU fan is a nice cool master one. Im goin water cooled at the end of the month.

 

These CPUS can be safely over clocked to 4GHZ and with a good cooler 4.2 GHz And it still be a stable system.

 

I couldnt find a speedstep option in BIOS. I did look.. but with is running at 3.40 i prosume were ever it is, is disabled.

 

Yes im clocking it via bios. Iv managed to clock it to 3.4GHz per core and yes i use CPU-z its a great lil application. With the overclock of 3.4 Ghz the cpus avarage temp is 45degrees so still running nice and cool.

 

Just setting it to 3.8GHz sets it back to 2.8GHz which is factory spec even though is bios it says 3.80GHz.

 

I used this guys guide:

 

uSyUcBfjy6o

 

And a few screen shots of my hardware/settings from CPU-Z and Real Temp to save me from typing:

Looks fine to me, it looks like you have increased the ram speed to 400MHz to increase the clock speed which is fine. Almost certainly intel speedstep kicking in as in your cpuz screen it shows a multiplier of 6x. And 400x6 gives you 2.4GH, its just running at a lower speed when you don't need the power.

 

You can probably find a bios option that disables it lowering the multiplier to 6x, I thought it was speedstep but some motherboard makers call it different things.

[DamanC]

Gigabyte boards call it EIST and C1E - Disable it

 

Ctrl + F1 in the BIOS to enable the hidden features, but you probably already know that.

[a98pmalcolm]

thanks for the replys... i have disabled CE1 Will look for EIST now....

 

OK an update i have it running at 3.40Ghz... And set the Ram valtage to 2.00v

 

http://img153.imageshack.us/img153/869/cpu340.jpg

 

But as soon as i try and set it at 3.80GHz it auto sets it self back to 2.80Ghz. So im still getting the same result.

 

Although im stress testing at the moe and im avaring 78 degrees so most probly will lower the CPU + ram valtage and leave it at 3.40GHx till i go water cooled at the end of the month!

 

UPDATE: On full load CPUS are running a lover avarage of 65 - 70 Degress which looks a nice satable setting for now after lowering voltage on ram and CPUs

 

But any ideas why the system refused to accept 3.80Ghz buy putting it automaticy dispaying 2.80Ghz in windows but 3.80Ghz in BIOS will be a great help as when i go ice cold cooler at the end of the month i will try to get them to +4.0Ghz....

 

Thanks

EIST - is in advanced settings I believe.

 

Are you using Samsung Ram?

 

Have you manually set your RAM timings?

 

Your CPU Voltage looks a little low imo, but if its passing prime 95 for 24 hours then its enough.

 

Every overclock is different, don't just follow one guide and take it as gospel.

[Matt H]

I've overclocked my PC and it shows up in the My Computer Properties box as being faster.

Well its what CPUz says, I just asked for 8GB from my local PC shop, Power C. Samsung RAM unreliable then?? Its been good so far...

 

You will have to excuse my noobness to this as im new to over clocking. But i havent manualy set my ram timings... How would i do that on the gigabyte motherboard bios and what timing do you think is best??

 

Regarding the CPU voltage i notched it up a lil put it on full load via Prime95 and they were getting to 80+ Degrees. Turned down the voltage a lil and it was avaraging 65 Degrees so i thought best to leave it there at that. As you said all overclocks are different due to different.

 

Thanks

Paul

 

EDIT:Ican see how to set the timings in the BIOS now. The timings are 6-6-6-18 but thats what samsung recomend for the 400Mhz DRAM iv taken it off auto and manually typed 6-6-6-18. Also put the CPU voltage to 1.3000. Ran prime59 for an hour and no errors

[DamanC]

Samsung RAM is entry level budget stuff and asking it to do more than its designed for wont do it any favours, it will most likely fail over time. Its also not great for overclocking and will probably install a ceiling that you wont be able to pass. Has it got heat spreaders installed?

 

I'm a little confused as to what's now happening, your upping the FSB to attain a frequency of 3.8Ghz, the PC boots but CPU Z shows a frequency of 2.8Ghz?

 

Is your multiplier fixed or set to auto?

PMing you now mate

 

multiplyer iv set to 8 and have the additional at +.05

 

Its very bizzar isnt it when its set for 3.8 or even a 3.6 as soon as u set it over 3.4 it just refuses to reconise what is bios!

[DamanC]

Whats states it not 3.4GHz+?

[a98pmalcolm]

Whats states it not 3.4GHz+?

 

3.40 is fine mate... just when i try and set it at 3.8Ghz..

[DamanC]

I mean what reports its not a 3.4Ghz + overclock?

 

My comp properties, CPU z, Speedfan?

 

PC boots happily, and does not fail to post with 3.4Ghz + overclocks?

CPU z mate, when i set it to 3.80GHz in bios it states 2.80Ghz and with test my CPU speed. Its 2.80GHz stock

 

When i set it at a 3.40 overclock its 100% fine and stats in CPU z its 3.40Ghz....

 

PC boots happy with 3.40 Overclock and ran 2 work jobs at the same time on prime 95 for 11 hours no errors and everything passed with the 3.40GHz overclock.... Max temp was 81 Degreeds but avaraged 75

 

No point testing the 3.80 GHz overclock till i can find out why CPU z + other programes states its a stock 2.80Gz CPU speed. Its really strange.. Theres gotta be a setting somewere if i take it over 3.40Ghz it states its 2.80... well its gotta be stock if a few aplications say it is... even though when restating and going into bios it says 3.80:blink:

[a98pmalcolm]

Update: Just noticed when setting the overclock to 3.80GHz the comp then restarts twice one after the other straight away when saving and exiting BIOS. But then saving and exiting BIOS when setting the overlclock to 3.40Ghz it just restarts once.

[DamanC]

The twice restart means the overclock has failed.

 

Ramp the V core up (bit by bit until it boots property) as well as the FSB (go for 3.6Ghz up to see if you can get it to boot (in one) but don't go stressing it as you will cook it.

 

Can you get it to boot in one?

[DamanC]

Fun isn't it

[The-Plethora]

A quick note about prime though, its going to stress your CPU far more than any app or game is ever going to make it work. People seem to seek a stable prime overclock as reassurance. I can prime at 3.6 but not at 3.8. No crashes in games at 3.8 so I run at 3.8.
