Official "Overclocking Help" Thread

[goleastro]

If anyone here has an i7 procesor and has overclocked please post your results..

So far i have got my i7 920 2.67ghz to 3.6ghz running stable on stock fans. I increased the frequency from 133mhz (stock) to 180mhz. I then increased the cpu voltage to 1.3v, and i left my ram (stock 1333mhz) on auto. I am quite happy with my results and i might try get further tomorrow.

hi i need help
ive got an amd phenom 2 965 black edition which is ment to run at 3,4 ghz ,but is running at 800 mhz
iv'e got an ecs amd 740g am2 motherboard.Every time i try overclock it to its proper speed it doesnt boot, and i have to reset my cmos.
please help its driveing me crazey

Hi all I need some advice on overclocking my Intel core 2 duo E8500 and my gigabyte 9600gt.

For starters the goal for my processor is 4 ghz. My current mobo is the Gigabyte GA-G31M-S2C. It supports DDR2 1066 but I am currently running 800.
My cpu's temperature is constantly 32 Degrees, when playing games it goes up to about 36/38 maximum.

I am going to invest in a new cpu cooler for the overclock [ Coolermaster Hyper TX2 ]

And as for case cooling I will be ordering 2 new 120mm fans and my side panel will be modified to take 3 x 80mm fans. I also have a pci blower extracting underneath my vga card.

For my graphics card I want to push it up at least 100mhz or so. Or if I can get it higher that would be great.

Please give me exact numbers and details on what to change my FSB and voltage to. And what I must change the voltage to on my graphics card.

Any advice or help will be greatly appreciated.

Here's a shot of my Gigabyte vga gamer hud utility. And all tabs of cpu-z just click links to show extra tabs.

I can tell you haven't fiddled with your BIOS just yet (since SpeedStep is on), I would advise you start googling around for settings and look at other peoples successful overclocks and of course their relative settings.

Your multiplier is dynamic since SpeedStep is on, this is no good for a successful O.C.

Did you notice in your CPU-Z, it shows you're running at around 2Ghz instead of your CPU's rated speed of 3.16Ghz... Your multiplier should be 9.5 not 6. That is because SpeedStep is enabled. Go to you BIOS and disabled it, also disable C1E, Max CPUID value limit and Vanderpool. Disabling those options in your BIOS should help with overclocking.

In order to get to 4Ghz, you'll need to pump your FSB from 333 to around 420 - 450. You'll need to add some extra voltage to your NB Core, your NB Termination and of course your CPU (there's a few other details I didn't mention here but you should read up on this stuff before doodling around in your BIOS). If your BIOS has an auto setting for your NB voltages then leave them auto (according to an Asus BIOS, I don't know Gigabyte). You will HAVE to add a little voltage to your CPU in order to stay stable at 4Ghz and don't attempt this without an aftermarket cooler, seriously.

Anyways, in order to determine whether your CPU, mobo and RAM can handle the stress I would advise starting smaller, like 3.5Ghz and work up bit by bit. Remember to run Prime95 with small FFT's for at least 12 hours to check if you have a stable O.C. and download RealTemp to keep a watchful eye on your CPU's temperature.

Sorry I did not comment on overclocking your graphics card, this is something I don't have much experience in and I'm not into OCing graphics cards. I tried it once and it didn't give me good results. To me, it's not worth lessening the life of your card. CPU's are much more robust than GPU's IMHO.


Seriously, if any one is vaguely new to overclocking, please check out this overclocking tutorial: http://www.tomshardware.co.uk/forum/...0001_11_0.html

Does, or can ram bottle neck a pc? I am using an i7 and im probably going to get the hd5850 but i have transend jet ram 1333mhz, timings: 8-8-8-20

Edit: cpu-z says my ram is only running at 534.6mhz and i have set it to 1333mhz in the bios (my ram is a triple channle 2gbx3 1333mhz set)

Sorry for the double post, but i really would like to know this. Isnt their anyone who can help.

And why does cpu-z show such low ram frequencies?

CPU-Z doesn't show the multiplied frequency. I'm not familiar with the X58 FSB speeds or DDR3 triple channel technology. I do know this, I have DDR2 RAM that runs at 800Mhz effective, in CPU-Z it shows as 400Mhz because it's "dual channel" it's ACTUALLY running at 800Mhz.

Does that answer your question?

What SPD timings does CPU-Z show? Is it the same as the timings specified on your RAM chips?

[RaptoR]

Yes RAM can bottle-neck a PC...i have no clue on the 5870 or wateva it is but its a new card so to be safe that your system isnt bottlenecked 1600-2000mhz RAM would be better :)

Thanks machine for your advice. I'm going to get a cooler before I overclock so you don't have to worry there.

Always a pleasure. Please read that article I posted a link to, it's choc-full of useful information to keep in mind.

I bought the ASUS P5KPL-AM SE at rAge so I could overclock my E2160 but when I change the frequencies in the BIOS and restart the system nothing changes, please help

Sometimes if your overclock is too overzealous your BIOS will automatically revert to default settings.

Did you follow my directions in the previous I made?

You should try taking a look at the tutorial I posted a link to.

What frequency did you attempt to set it at in the BIOS?

I set it to 333Mhz and I'll take a look at the tutorial

[BTROG]

The part where I change my cpu frequency and ram frequency is under the JumperFree Config so do I need to disable the jumper or something in order for my frequency to change to what I set it to?

@BTROG

Listen 333Mhz is WAY too much for a 1st time overclock for your CPU... That would make it go from 1.8Ghz to 3Ghz... That's a 67% OC (too much).

Plus if you're not adding a bit of voltage the CPU would end up being too unstable to even start Windows let alone POST.

With your CPU's multiplier of 9 and your FSB running at a default of 200Mhz (yes that's right), I would advice something smaller. Try around 266Mhz (33% OC), that will overclock your CPU to 2.4Mhz. Also, remember to disable "speedstep" in your BIOS.

Download CPU-Z here: http://www.cpuid.com/cpuz.php

Run the program and do screen shot and post it here under your default CPU setting first and I will advise you on how much extra voltage to pump it. It normally should be around 0.05 of a volt extra. Please be extra careful when changing the voltages as being too aggressive can burn out your CPU.

Hi guys,

I am planing on getting an i5 750, and I've never overclocked before. Is it worthwhile to overclock a brand new cpu (I read Ch@pS's thing and he rates it's always worth OCing).

The new PC will be pretty high end already. Planning on: i5 750, HD5850, 2x2GB ram etc
What kind of speeds can you comfortably overclock that cpu to?
Are you going to be running a serious risk of wearing out a cpu (i.e. is it worth overclocking if its brand new)?
Where is the line where the benfits outweigh the risks?

Also somebody posted about 1333Mhz ram posibly bottlenecking a new Gfx card like the HD5850? Any comments on that?

Hi guys,

Snap. Now guys. Ive been reading up about these new i5 and i7 CPU's. Apparently unlike the core2duo CPU's these have no FSB? So its now -harder- to OC because you dont just change the multiplier its more complex?

Huh? My i7 is at 3.26GHz and it's just normal overclocking. (well actually this i7 is the first thing i have ever overclocked, so i don't know how 'normal' overclocking is done)

[FEN1X]

How did you OC it?
