hello brother, i need you assistance regarding
overclocking my system , i need perfectly stable and
less heat environment for my cpu.I'm going to provide
full details about my system .

these are all default settings in my bios i didn't touch
those and i'm waiting for you answer. help me

Overclocking is all trial & error. We can suggest some settings to try, but no one can guarantee stability. YOU have to make it stable by adjusting the settings correctly - getting the voltage right is critical. Also, overclocking almost always increases the CPU temp, sometimes just a little, sometimes a lot...once again, it all depends on you getting the settings right. From what I've read, the E7300 will easily do 4.0GHz, but it's not gonna happen with your setup because of the RAM. Shoot for 3.33GHz instead.

CPU Host Clock Control - enabled
CPU Host Frequency - 333MHz
PCI Express Frequency - 100MHz

Do you know how to recover if the system becomes unbootable?

Said settings .. I think perhaps not suitable for me, because ihave tried that settings , blue screen appeared and some person suggested me not to touch PCI Express's frequency.. so .. Just I need settings for 3.0ghz thats it . and let me know answer

There are numerous other settings that need to be addressed to successfully overclock, not just the 3 that I listed. The reason you're getting the blue screen is either because you didn't lock the PCIe at 100MHz, you didn't adjust the CPU:RAM to run 1:1 ratio or you didn't increase the CPU voltage. It could be any one of those or even all 3. Like I said, it's all trial & error - but YOU have to know what you're doing and WHY.

For instance, the reason the PCIe should be set to 100MHz is to keep it from changing. 100MHz is the default speed. If you leave it set to AUTO, it will automatically increase when you increase the CPU Host Freq. The same thing happens with the RAM. Whoever is coaching you apparently has no idea what they're talking about.

The PCI-e MUST be locked at 100MHz. And the RAM has to be adjusted to stay in step with the CPU. With the CPU Host Freq at 333MHz (1333MHz FSB), the RAM also has to run at 333MHz (667MHz DDR). All Spread Spectrum settings have to be disabled & EIST (SpeedStep) has to be disabled too. And as I said in my other response, getting the CPU voltage right is critical - if it's too low, the system will be unstable, lockup or become unbootable. If it's too high, the temp will increase & you run the risk of damaging the CPU. All CPU's are internally protected from overheating, but they are NOT protected from overvolting.

"and some person suggested me not to touch PCI Express's frequency.. so .."

Some person is wrong. Like jam said, it must be locked at 100Mhz if you want to overclock.

ok i will adjust my pci to 100mhz
and then how can i adjust cpu:ram to 1:1(no idea)
what are spread spectrum settings(no idea)
i have disable EIST and C1E states
and how much voltage i could pass to my cpu give me settings.

prior posting

my trial was some3.6ghz and voltage of 1.2v(from 1.18000v)
but pci-auto then only blue screen has come.perhaps bluescreen due to pci-auto. kindly clarify me and provide some settings which can be at safety of my C.P.U

regards sandy

Ratio 1:1 by increasing your fsb to 333mghz, because your ram has 667/2=333mghz.Or by matching cpu fsb and ram frequency.See response # 1

hi bros, after longtime i read previous discussions which were made. please please i request you valuble suggestions. see
these are setting i changed please make a note
cpu clock 9x
cpu host frequency 333
pci express 100
Ram latch-333
cpu vcore 1.18750v to 1.19375v
these changes i made
with above settings cpu was running at 2.9ghz
and tested with prime95 for 1 hour everything fine 100%load and temp 65.
but mean while i tried to open mozilla no blue sceern but completely hanged(might not be problem of stability)

one thing i observed even ichanged
cpu vcore 1.18750v to 1.19375v i observed in CPZ core voltage changes 1.15 ,1.16 even voltage not to default also, why i don't know.

next trail
based on success of above stability
just switched to bios and just changed cpu clock to 9x to 10x
and came to windows with in 2 minss blue screen ,now i'm completely handicapped, what can be changed..i need you thought. You could aid me.

regards and thanks
