my e4300 can't pass 2.00GHz ?

post #1 of 11

My E4300 with a biostar 945GC Mobo (bad mobo i know but where I live there is no LGA 775 mobo else the G31 and the 945GC) can't pass the 2.00GHz i can't understand why.. can s.one help me ?
here is a screen of the settings :

You need to be able to raise FSB, but it looks like you can't with that mobo.

nope i can up to 300.. the CPU Clock (is the bus of the CPU) i already have rise it from 200 to 220 but it won't pass 220..

Your board has an old 3 phase/unsinked VRM design. The VRM on that board also uses 2 transistors (normal) per phase and no driver (or even a cheaper 3rd mosfet) . It will have bad voltage regulation to the chip (severely limiting your OC), and you also risk burning it out by pulling more power than it can handle through it. I wouldn't OC on that board at all.

Yes, Sir..thanks for the infos..

You seem to be changing the "FSB Termination Voltage" rather than the actual CPU Voltage. Find out what the CPU Voltage is. I ran an E4300 at 3GHz, IIRC it needed 1.3v for that overclock. This was on an Asus P5N-E SLI though, so a bit higher quality board.

nope i did not change the fsb voltage smile.gif plus the cpu voltage can be raised by (bios options) : "5%" "10%" "15%"

While for most chipsets setting PCIE=100 is the best,in some older chipsets like 945, FSB & PCIE are linked.
As a result you should raise PCIE clock to overclock.
So set PCIE clock at auto first,because some motherborads can raise it as necessary.
If that doesn't work,then raise it manually.Try FSB=240 & PCIE=102-105.
Increase vcore as needed & keep dram freq. close to 800.

Good luck!

I tried it, it works..the PCI-E clock 105 for 240 FSB..
it's now @ 2.10GHz..i'm less CPÜ limited..
