re: CPU Overclock List & Discussion Thread

Check the SPD tab for the memory it show show the EPP (extended performance profile) settings. Set the RAM voltage 'manually' to that. And remove all 'auto tuning' functions..not sure what they would be for your board, but still like EIST/Spread Spectrum.

re: CPU Overclock List & Discussion Thread

Am posting The screens , Before that I have one doubt - Do i need to increase the NB frequency & HT link to 2.4Ghz & reduce my Multiplier to 12X

Damn some one help me Its 140W TDP proccy , when i OC to 3.5ghz CPU voltage 1.42 It stable 59deg Full Load Temp

OC to 3.7Ghz 61Deg not stable also That DAMN error

ERROR MESSAGE

"YOU MAY NEED TO BE LOGGED OFF DUE TO POWER DISTURBANCE" But no Restarting & NO BSOD

COULD ANY ONE TELL ME

wat's The

NB Voltage
DDR 2 VOLTAGE for 880Mhz

I have nice NB cooler motherboard but not stable yyy ??

@ topgear

Am not not using Overdrive only in Bios i am using it , also i ll post screens for 3.4Ghz Help me with OC - Thank u

Do you have black edition cpu ?

looks like your cpu is not getting enough juice at 3.7 GHz - you need to increase the volt.

Set CPU volt to 1.4625V @ 3.7 Ghz ( cpu FSB 255x15 )
Set mem clock to x3.33
Set mem volt to 1.9V.

@ top gear & asigh

I just Leaving it for now I am Going to Get New Proccy & Mobo saving money for that Will OC The Phenom 940 to [extend LAst] wen i get those New one's - right now need to search my work !

Hi guys..ill like to oc my rig but i am a noob in this so need help..
my sys config is in my sigi...'
Will b waiting for ur replys...'

re: CPU Overclock List & Discussion Thread

The stock cooler is not so great so if you want to achieve higher speeds like 3.8 Ghz or more you should first get a good after market cpu cooler.

Q: How much Core-i5 750 can be overclocked to?both in stock cooler also & custom cooler......

Also HD5770 overclocking details????

I don't has much experience in core i5 OC.

I won't recommend Ocing core i5 750 more than 3 GHz with stock HSF as the stock HSF is not that great. It looks like it was built for old generation 65W TDP cpus and core i5 750 has TDP of 95W.

But as long as the temp is under 70C you can OC it further.

With a good after market CPU cooler you can OC the cpu upto ~3.8-~4.2 GHz.

HD5770 can be OCed using Riva Tuner. Expect to get ~75-~100 Mhz clock speed and ~600-~800 Mhz mem clock increase.

BTW, do remember to keep the tempo under 85C though.

re: CPU Overclock List & Discussion Thread

Need some suggestion regarding Phenom II 955 overclocking. I am using AMD overdrive to overclcok and reached 3.6 GHz safely by just increasing the Multiplier to 18X. It is stable most of the time but sometimes system getting hanged when playing games for several hours.
I need suggestion regarding stable voltage, memory multiplier and NB voltage values for stable overclocking @ 3.6 GHz to 3.8 GHz.

Better to do it via BIOS. Desktop utilities are not that reliable.

 

[Cilus]

re: CPU Overclock List & Discussion Thread

Actually I nee some suggestion regarding the stable values for CPU voltage, memory multiplier NB voltage etc for a stable 3.6-3.8 GHz overclock. Once done, I will change the values in BIOS. AMD Overdrive even the feature to update the BIOS directly and I've tested it... working fine.

 

[topgear]

re: CPU Overclock List & Discussion Thread

Not every mobos and cpus can be OCed with same values even if they are from same series. I'll suggest you to wait till your new mobo arrives.

BTW, If you can ditch Over Drive and OC using bios options. Ocing through Bios is more fruitful always IMO.

AMD OD can handle only multiplier increase , 18X is the maximum increase for 955 , if u raising multiplier the heat will increase if u have good mobo reduce the multiplier then just increase bus speed slowly to reach the potential speed !!

Make sure ur RAM has heat spreader !!

 

[topgear]

re: CPU Overclock List & Discussion Thread

^^ I think 955BE has unlocked multi so why it's limited only at 18X - is this a limitation of OD or the cpu itself ?

If you run your Rams at specified speed or 10% more I think it's safe even without heat spreader for DDR3 1333 Mhz modules. They though have higher speed than DDR2 their volt rating and power consumption is low so the heat generation will be a little bit less.

Make sure to set ram and FSB multiplier correctly and always try to oc with a third party cpu cooler installed.

re: CPU Overclock List & Discussion Thread

^^^ I just mentioned that if he increase more than 18 the heat will be more ,, 955 is almost same as my 940BE the heat is intense .

 

[topgear]

re: CPU Overclock List & Discussion Thread

^^ Ok .. I got it - The higher TDP rating ( more power consumption ) is the reason for the heating issue I guess.

re: CPU Overclock List & Discussion Thread

Hey guys I was checking some stuffs in BIOS (Specs in my siggy) and found this under AI Tweaker, there is an option, CPU LEVEL UP- Auto, i7-975-3.33GHz, i7-Crazy-3.7GHz and AI Overclock Tuner- Manual, Auto, D.O.C.P, X.M.P. Now my query is, is this overclocking? As far I knew overclocking could be done only by additional softwares, but is it possible via BIOS?
And if I do overclock which speed should I choose? 3.33 GHz or Crazy 3.7 GHz and I will also like to be informed by the Advantages and Disadvantages if I overclock. Is it really needful and Safe? Will it increase my CPU temperature much?
Thanks in advance.

re: CPU Overclock List & Discussion Thread

First of all what you knew till today was partially true. Oc can be achieved by software and Bios ( HW ) both. Mid to high end mobos comes bundled with or supports some kind of Oc apps with which a limited amount of OC can be gained. But if you want a TRUE OC and want to keep every possible setting under your control while OCing then you should better use Bios Ocing as it's the best way to achieve OC and push you hardwares to the limits. Even if you get a mobo which don't support software OC most of the chances are it has tweaking option in bios to do some OC.

Obviously that's OCing. That's just an option to automatically OC your cpu using bios ( Read Ai option ). That's AI ocing is a good starting point to test a little bit OC but it won't give you precise control over everything while ocing. To do that you need to do the necessary changes in bios ( like cpu volts, qpi link speed, mem speed, mem ratio setting, mem volts ) manually.

For you 3.33 Ghz should be a fine starting point. At 3.7 Ghz your cpu will use more power ( read volts ) and that will increase your cpu temp as well.

Before ocing note the temp of your cpu using real temp, measure volts using cpu-z. After setting a little Oc in bios ( say 3.33 Ghz ) again run those apps and this time run a OCCT or prime cpu stability/load test to know if the oc is stable. If it's stable and the temps are in safe limits you can proceed further.

re: CPU Overclock List & Discussion Thread

Thanks, how will I run OCCT or Prime CPU stability/load test?

Anyway I tried to OC to 3.33 GHz, this is the results before and after Ocing,
Before- CPU-Z Validator 3.1
After- CPU-Z Validator 3.1

And Real Temp shows temp as- 39-35-38-32, so it's a little increase. But the CPU Voltage as you can see is @ 1.2V.

and this is the Sensor Test result after OCing,

UPDATE- OC'ed to 3.7 GHz, Core Voltage is @ 1.34V. Normal Temp is like- 43-44-42-37
Here is the sensor test and CPU ID screens,

You can see @3.7 GHz sensor test the temp reached up to 81°C, Is that normal?

Please mention if anything I did wrong or the results.
Thanks in advance.
