Why are you running the CPU underclocked ? The multiplier should be 10 instead of 6. Clocking the CPU properly would help you to gain certain level of speed.

So,

-In the Fox Central Control Unit

Set Fox Intellegent Stepping on Manual, disable Spread Spectrum, set the CPU and RAM voltage manually (at their default settings), lock PCIE Freq @ 100 MHz.

The FSB/DRAM ratio should be set to 1:1 for best performance.

Select DRAM Configuration and press ENTER.

Set "DRAM Timing Selectable" to "Manual", and set the field value to 533MHz.

-In the Advanced BIOS Features:

Go to "CPU Feature" sub-menu and set "Intel SpeedStep Technology" to Disabled.

Now you are all set to start overclocking. Press F10+Y+ENTER

To be continued...

Ah...you right....Didn`t think about it....

No worries then. When the CPU needs to run faster, the multi will jump to 10x.

Why do you need voltage now? Voltage DOESN`t increase speed.

So far, do the things I suggested.

If you set the FSB to 270, the CPU should run @ 2700MHz.

If the system boots successfully, download Prime95 and run it for...say 15 minutes. (15 minutes is not enough...however, if no restarts, you can proceed). And yes, monitor the load temps using SpeedFan (anything up to ~65 is OK).

So, if no too much heat or crashes, set the FSB to 275 and perform the bolden part. Do that until the system crashes or won`t boot. If it won`t boot, clear the CMOS settings using the on-board battery. If it crashes, go back to the last *stable* clock.

But, it`s too early to talk about it. Now, just set the parameters that I told you to set and raise FSB to 270 (and test stability).

CMOS Settings are infact all settings that you see in BIOS (including overclocking settings).

When for some reason, the system won`t POST after raising FSB (nothing appears on the screen), you need to reset CMOS Settings to their defaults.

Since you can`t access BIOS so as to do that, you must reset them using the on-board CMOS battery. (it`s located on the motherboard, the location on the motherboard varies.)

Here is a picture of the CMOS battery, so you can recognize it:

http://support.oslri.net/image/cr20...

Just unplug the computer power cable, remove the rear chassis cover, locate & remove the battery, wait for 1 minute, insert the battery (be careful of the battery polarity.) Then put back the rear chassis cover, plug in the power cable, and you`re good to go.

As I said, you need to do this only if the system fails to POST.

Select DRAM Configuration and press ENTER.

Set "DRAM Timing Selectable" to "Manual", and set the field value to 533MHz.

That will do it. If you have configured the other settings, do the above thing and start overclocking. After raising the FSB to 270, don`t forget to test stability and to post CPU-Z log (like you did in the first post).

Good Luck!

"i dont se voltage anywhere"

Enter the BIOS, then open the Fox Central Control Unit menu. Find the Fox Intelligent Stepping & change the setting to Manual...you should then be able to do what you want:

CPU clock = ?
PCI Express Clock = 100MHz
CPU Voltage Regulator = ?
DRAM Voltage Regulator = ?
Spread Spectrum = disabled

To disable SpeedStep, go to the Advanced BIOS Features menu, highlite CPU Feature & press Enter...then go down to EIST Function & disable it.

I'm curious, have you ever overclocked before?

Wonders why does he need voltage settings now. The CPU should go to 2.75 GHz at stock voltage (at least). Of course, you`ll need it if you want to reach 3 GHz, but we`ll talk about it later (when the system restarts suddenly / won`t POST).

OK, I can see that you are following my advices, which is good. Everything seems to be OK, which is also good. When you get home, please check the temperatures before you stop prime95.

If the CPU temp is less than 70, and prime95 doesn`t show any errors, increase FSB to 275. Then you know what to do: prime95, watch temps. If stable, increase FSB for 3MHz, and repeat this until the system keeps restarting or it doesn`t POST. If it doesn`t post, read Response # 9.

About my last comment...

You need to raise voltage when the system is unstable (rebooting suddenly and similar). However, before you raise the voltage, please let us know if the system is unstable, so we can suggest what to do.

Do you have the CPU Clock Ratio set at 6X or is EIST still enabled? You're wasting your time running prime95, your CPU isn't overclocked at all, it's still underclocked. Not only that but all you've done is increase the CPU frequency by 3.33MHz. You realize that the default FSB speed of the E7300 is 1066MHz, right? With a CPU frequency of 266MHz? Here's what you have:

"Core Speed 1620.0 MHz
Multiplier x FSB 6.0 x 270.0 MHz
Rated Bus speed 1080.0 MHz"

You've managed to overclock the FSB a whopping 1.25% but the CPU itself is still underclock by 1046.66MHz - wow!!

"OK...if the multiplier is 10x, you can proceed to 275 FSB"

275 is not the FSB, it's the CPU frequency. And it's only 9MHz higher than the default frequency of 266MHz. I'm all for being safe/cautious when overclocking, but we're at 25 responses & as far as we know, he's still running underclocked.

mrsandman,

We don't need to see your Prime95 results. It's useless to us, plus you haven't even overclocked enough (if at all) to worry about instability. Go with kuwese's recommendation in response 25.

This is getting a little frustrating. There is no setting for 1:1 ratio. That is something that YOU have to do yourself. Let's back up a little & I'll give a quick explanation.

You should always work with frequencies, not bogus speed ratings. The frequencies may not always be listed as such, so you at least need to know how to convert back & forth. For instance, when you see the FSB listed as 1066MHz, that is NOT the frequency, it is the speed rating based on "quad data rate technology" (aka QDR). You don't need to know what that is, all you need to know is that to determine the true frequency, you need to divide by 4.

1066MHz FSB / 4 = 266MHz frequency
1333MHz FSB / 4 = 333MHz frequency
1600MHz FSB / 4 = 400MHz frequency

Memory speed rating is based on "double data rate technology" (aka DDR) so to determine the true frequency, you need to divide by 2.

DDR2-533 = 533MHz / 2 = 266MHz frequency
DDR2-667 = 667MHz / 2 = 333MHz frequency
DDR2-800 = 800MHz / 2 = 400MHz frequency

Your CPU has a default FSB speed of 1066MHz (aka 266MHz frequency) so to maintain a 1:1 ratio, the RAM needs to run at the same frequency....in other words, 266MHz. To do that, you either need DDR2-533 RAM, or you need to underclock the RAM to 266MHz to match the CPU frequency. Once you manually dial down the RAM setting to 266MHz (or 533MHz, depending on how your BIOS lists it), you won't have to mess with it again. You have created the 1:1 ratio. The RAM frequency will now stay in sync with the CPU frequency...increase the CPU from 266MHz to 275MHz, the RAM will automatically run at 275MHz...increase it to 300MHz, the RAM will automatically run at 300MHz, & so on. Make sense?

"im now at 287 cause a option called intelligent stepping or something... that i select "step 3"..."

Do NOT use Intelligent Stepping! You were already told that in response 12. Set it to MANUAL, then manually configure the settings. Go back to response 12 & re-read it.

Here's what you need to do:

CPU multiplier = 9x
CPU frequency = 333MHz
RAM frequency = 266MHz
PCIe = 100MHz
EIST = disabled
Spread Spectrum = disabled

If you can figure out how to do the above, the CPU will run at 3.0GHz at 1333MHz FSB & the RAM will run in sync at 667MHz.

If you want to take full advantage of your RAM, set the CPU multiplier at 8x & the CPU frequency at 400MHz...the other settings can just stay as they are. If you can pull it off, the CPU will run at 3.2GHz at 1600MHz FSB with the RAM in sync at 800MHz.

NOTE: notice that I mixed frequencies with QDR & DDR speeds...it's up to you to mentally make the conversions.

"it resets idk why"

Are you saving your settings before exiting the BIOS menu? It *may* be reseting to 266MHz because you didn't lower the CPU multiplier.

This should not be so difficult but you need to understand that the way I write it is not necessarily how it is displayed in the BIOS menu. My mistake is assuming that you know what you're doing :-)

Do you have a copy of the motherboard manual? Everything you need to know is there & is explained in detail.

I just re-downloaded your manual & had a look at the BIOS chapter. The CPU multiplier setting is called "CPU Clock Ratio" & is listed under the Fox Central Control Unit menu.

I think the CPU won`t allow to lower the multiplier. If that`s the case, try 300x10. The RAM will run at 600MHz, a bit downclocked, but is surely better than running it at stock.

"Huh? Quite frankly, you`ve lost me here"

Go back to response # 29 & read it.

Let me ask you this. The E7300 is said to run at 1066MHz FSB, right? Then why is it clocked at 10 x 266MHz rather than 2.5 x 1066MHz?

266MHz is the CPU frequency, 1066MHz is the FSB based on QDR technology. The frequency is the actual speed, the FSB speed is purely theoretical & assumes total saturation of the bandwidth. They are two completely different things. If you don't understand that, try this:

Let's say you have two cars (#1 & #2) that are capable of traveling at 266MPH. They both leave the same place at the same time, they're both traveling to the same place & they're both taking the same route, meaning that they will both arrive at the exact same time. The only difference is car #1 contains only one person, while car #2 contains four people.

Would it be fair to say that car #2 traveled at 1066MPH because it carried 4x as many people as car #1? Of course not! But that is exactly what Intel does when they say the FSB speed is 1066MHz.

If you don't know the difference between frequency & FSB, you probably shouldn't be advising people on how to overclock.

Now you can see why I suggested to try....say 280x10 first.

If you followed the instructions we gave you, most likely the CPU needs more voltage so as to work at 300x10.

Now we`ll try to find the highest frequency at stock voltage. Try 280x10 and see what happens.

Yes it does.

"ok guys this is weird"

Yeah, this is weird all right.

Either you're not paying attention or you're not understanding the manual. It states in plain english what you have to do. And Mr FixIt isn't helping by not knowing the difference between frequency & FSB & blindly telling you to jack the frequency up to 300MHz. Everything you need to know is in the manual and has been explained in this thread. It might be a case of "too many cooks". I'll give all the BIOS settings to you in one response. If you can't pull it off after this, you're on your own. The only thing I can't help you with is the voltages. I don't know what the defaults are for your CPU or your RAM. Intel supplies a range (0.85V – 1.3625V), but not a default. From googling, the default appears to be 1.20V but I'm not 100% sure. Once you know what it is, then you can bump it up a little bit if necessary.

1st of all, let's make sure we're using the same manual:

http://www.foxconnsupport.com/downl...

I'm going to give the settings to overclock to 3.0GHz at 1333MHz FSB (for Mr. Fixit, that's 333MHz frequency) with the RAM running in sync at 667MHz DDR (once again, that's 333MHz frequency).

On page 20 of the manual, you'll see the main menu. We'll start with the Fox Central Control Unit:

CPU Clock Ratio = 9x
Auto detect PCI Clk = enabled
Ratio free = disabled
Fox Intelligent Stepping = Manual -- when manual is selected, the following can then be adjusted:

CPU Clock = 333MHz
PCI Express clock = 100MHz
CPU voltage Regulator = ?? need to know your default voltage - use Auto for now
DRAM voltage Regulator = ?? need to know your default voltage - use Auto for now
Spread Spectrum = disabled

> DRAM Configuration -- press Enter to bring up that menu:

DRAM Timing Selectable = Manual
CAS Latency = Auto
DRAM RAS# to CAS# = Auto
DRAM RAS# Precharge = Auto
Precharge Delay = Auto
System Memory Frequency = 533MHz

Under Advanced BIOS Features:

> CPU Feature -- press Enter to bring up that menu:

Delay Prior to Thermal = 16 Min
Limit CPUID MaxVal = Disabled
C1E Function = Disabled
Execute Disable Bit = Enabled
Virtualization Technology = Enabled
EIST Function = Disabled

Save & Exit Setup = Y

Post back with the results.
