not all samples are equal - DO NOT EXPECT YOUR SAMPLE TO OVERCLOCK LIKE SOMEONE ELSES

start with ram 1:1, slack timings and stock voltage (ram) + 0.1v, processor - 45nm.... 1.45v max if i remember correctly - see how you go

I have already set my FSB: DRAM Ratio to 1:1 in each and every clocks and to make it stable i have given CPU voltages to 1.4V too and DRAM Voltages to 2.20V also

You might need to overvolt the cpu if you really want that 4.0GHz. Though you should be aware that with overvolting (beyond Intel's recommended) the chip might die anytime.

* Your ram seems to be running at 890MHz, what is the brand and model of your ram?

You may not be able to reach 4.0 GHz. Every OC'd system is a case of "YMMV".

Try running at 2:1 (memory running at half speed) just to possibly eliminate your memory as the source of the problem.

But I have heard that 1:1 is the best ratio and how to run at 2:1 ??

Coz whenever I increase my FSB my RAM frequency also increased with it
May 25, 2010 11:46:45 AM

Quote:
Running 800mhz ram at 890mhz is likely your limit.

Like jsc said, change ram ratio to 2:1 and cut the ram speed down.

It's unlikely you'll get 4ghz stable though.



My RAM default speed is 1066 MHz with 5-5-5-15
May 25, 2010 11:47:45 AM

As i have stated above that I want to keep the 1:1 ratio that is why i have set it to 890 MHz with 4-4-4-12 coz whenever I increased FSB, DRAM Frequency also increases with it
May 25, 2010 3:44:51 PM

Is anyone on tomshardware forum who can help me?
May 25, 2010 7:02:21 PM

that board and cpu should do 4ghz easy. i suspect your ram may be the problem though. your voltages all look really high to me for 4ghz.

ill just throw this out there for you too try if you want if you have an oc profile in your bios you should have one you can save you current settings in there and return too them easily later if you want.

so set everything too auto basically return too default settings. then set your ram and its voltage too there rated specs. Now set the front side bus too 450x9 and ai transaction booster too manual that should expose common performance level which you want too raise up like try level 13.

now try and boot it up if it wont boot or is unstable set nb voltage too manual and start at 1.35 volts and raise it up as you need to trying too get it too boot/stable. gl :hello:

Have you tried it with your timings at 5-5-5-15? My ram spec is about the same and at 900mhz i still have to use the timings used on 1066mhz.

It's usually good to cut your ram out of the equation while you OC your CPU. This will make things MUCH easier. Get your CPU stable, then work on trimming your RAM timings.

that's too bad :ouch:  you would think with that board and cpu it would do 4ghz.
if you set everything at auto and ram at its rated voltage and timings whats the highest fsb you can start windows up at?

No, I do not think so. This proccy is overclockable upto 3.8 GHz easily atleast and my mobo is damn excellent overclocker.

whoa something is defiantly going wrong there i have a p5q pro and a 9650 and i just booted it at 500fsb with just a few changes in the bios nb at 1.48 and common performance level at 11.

your mother board is alot better then mine too makes me think there is something going wrong with your ram.
May 26, 2010 3:37:53 PM

I don't think so that there is something going wrong with my RAM, coz @ 4.0 GHz when I set my FSB: DRAM ratio to 1:1 with 4-4-4-12 and even 5-5-5-15 @ 1.8V or even 2.0V, it's does not booted. At 4.0 GHz when I unlinked my RAM and set it to 1066 MHz with 5-5-5-15 with 2.0V, it does not booted

Nobody said that there is a 100% guarantee that you could go X high with A processor and Y high with B motherboard. Believe or not, overclocking also requires luck.


* Have you tried setting to the lowest ram speed, then increasing the FSB to something higher than 333? You might find an FSB hole and be able to work with something below 400 and 333. (If you're lucky, it might boot with some higher value, i.e. 350, 380, etc).

How old is that PSU ? I think you might be lacking watts/amp . I found a discussion that states it puts out 34a on its 3~12v rails, thats a little over 400 watts.

Presently, I am running it at 400 MHz FSB x9 which means 3600 MHz i.e., 3.60 GHz with 400 MHz DRAM Frequency with 4-4-4-12 with 1.8V and It is stable. So I want to run it at 4 GHz with 890 MHz DRAM Frequency so that the ratio will be 1:1 so I have tried to run on 4-4-4-12 and even on 5-5-5-15 on 890 MHz with 1.8V, 2.0V, 2.2V also but not stable. Also have given NB Volts above 1.4V, no stable.

PSU is 2.5-3 years old and do u really think that im running out of watts/AMP and yeah My PSU gives 34 AMPS on 12V RAIL with 408W output. So I have calculated the wattage of my running RIG @ 4.0 GHz with CoolerMaster PSU Calculater and found that my system needs minimum 568W :(  :(  .

Have you tried jumping to 410, 420 or 430? If you're lucky it might boot at any of those settings. Relax the timings when you try it to eliminate more variables.

Go back to 400MHz and then start working up at 5MHz or 10MHz increments. Find the fastest speed that it will boot and load windows at, then run Prime95 for awhile and see how long it runs without failing. In my experience loading Windows and withstanding long periods of prime95 are 2 different things. You really need to find the max. speed that it will run prime95 for an extended time without failing. That is your maximum overclock. Some people want to run 24 hours straight, I'm impatient and usually don't run it that long.

It may well be that your CPU won't run at 4GHz but I would bet that it would run closer to 4.0 than to 3.6.

One other thing that hasn't been mentioned- did you say if you had used that ram before or not? I was upgrading one of our older machines to 8GB and had intermittent failures with it. I finally discovered that it would not run for a long period of time with one of the modules in it. So it is possible that you have a marginal ram module. You might try it with some other ram if you have any available.

At that point, you're probably going to need to up the voltage (probably beyond what Intel recommends) to get your 4GHz.

Could you double-check if this is indeed your processor:
http://processorfinder.intel.com/details.aspx?sSpec=SLB...

If it is, looks like you could push it to 1.3625V, which may make 4.0+ possible.

yes, this is my processor, but now I am unable to come on desktop @ this settings 445 FSB x 9 = 4005 MHz, with 1.33125 V CPU V, 2.20V DRAM @ 890 MHz with 4-4-4-12.

Also, at this settings too - 1.36250V(Max limit of my CPU Voltages), with 1.80 DRAM Voltages @ 890 MHZ with 5-5-5-15 and I have given upto 2.04 voltages to DRAM at this setting. Also I have given upto 1.43 NB Voltages at this setting - CPU Frequency - 4005 MHz, RAM Frequency - 890 MHz(5-5-5-15) with 2.04(Max I have given) with 1.43 NB Voltage max i have given till now and the result is unstable on the windows welcome starting screen.

Also tell me that Do I really need to give voltages more than 1.80V to RAM @ 890 MHz with 5-5-5-15????????????????????

Coz I my RAM are rated at 1066 MHz with 5-5-5-15 @ 1.80V

Now what to do to make it stable????????????????????????????????????????

Find the portions about 'NB Strap' or NBCC.


If you don't want to read:
Quote:
If your memory is still not yet running near its stock rated setting you are safe with that. Try increasing your CPU voltage or your NB voltage. Continue this process of increasing FSB and voltage as necessary until you reach your goal. Always be mindful of what your NBCC is. You need to know what strap you are in, and where you are in your current strap. If you hit a ‘wall’ where it seems like no level of voltage will make you system stable, try increasing your FSB by 20 or 30Mhz, or to the next known NB strap. At some point you may find that you are having errors in terms of Windows booting because of hard drive corruption or you may find video card instability. This is your cue to increase your SB (Southbridge) voltage and lock your PCI to 33.33Mhz and your PCIe to 100Mhz. This will help ensure stability. If you continue to have stability issues you can increase your PCIe frequency even further. However, I would not run more than 110Mhz. Always leave your PCI frequency at 33.33Mhz.
