OC-ing E4500 Problems

[Tizzix]

Hi there everyone,

I know that this thread may be opened a few times already but i seriously need help with this overclocking stuffs.
Im new to OC and i have read many guides from many different websites..i just don't really get it...

First of all my specs
Win7 x64 Home Premium
Intel C2D E4500 @ 2.2Ghz (Conroe)
Gigabyte EP45-UD3R
2x 2GB Corsair Gaming 800MHz RAM 5-5-5-18
Gainward HD4850
Xigmatek Red Scorpion (S1283) CPU cooler
Xigmatek NRP-MC751 (750w)
250GB HDD


There are questions i would like to ask first..
1) I have selected a Vcore within BIOS for example 1.32500v (Default for E4500) *correct me if im wrong thx
However when i boot into windows (without any OC) and load up CPU-Z..it says 1.2-1.28v ..i have no idea why is it like that..

2) Most of the OC guides have this RAM ratio thing and most of them said that 1:1 ratio is the best..but i have no idea how to reach it..

3) with the current settings below..i cnt boot into windows..it just loads til the windows logo and then restart itself..what is the problem of it ? i have tried to increase the Vcore to 1.38v and its still the same...


For now what i did in BIOS is that

help is really appreciated

Isnt there anyone who can help me ?

Give it some time. I wish I could help but I dont have any experience with C2D.

Also, CPUZ wont always show vcore the same as what you set it to in bios. Droop comes into play. You could enable load line calibration as that will help get you closer to bios vcore once in windows.

Might be some relevant info in this thread:

erm..judging from your experience from other processors....roughly what could possibly wrong or what should i add in?

Try raising your CPU clock ratio/multiplier to 11x while at the same time setting your CPU Host Frequency to 272MHz, and then set CPU voltage to say 1.34V (only if necessary, try default setting first), while keeping your memory at or below its rated speeds if possible (that should lessen the chances of memory being a stability factor).

If your E4500 performs anything like my E4400 it should be able to reach 3GHz at stock voltages fairly easily (I'm guessing by the info in your original post that this is your intended target speed), it just might not like such a high FSB (per your specs of 333MHz) with standard voltages.

1. You're dealing with two things here, first vDrop where the voltage at idle literally drops below what it is set to in bios (on my own board I have it set to 1.28125v, but in CPUID HWMonitor it shows 1.25v) , second you have vdroop which is where the voltage tends to "droop" below the idle voltage when under heavy loads (for instance, on my board it droops from the normal 1.25v down to 1.22v).

2. Via your System Memory Multiplier. Based upon your given specs, I believe you are at 1:1 right now, if I'm not mistaken.

3. Either a. something isn't getting enough voltage to remain stable, or b. something is overheating (probably your Northbridge chipset, if anything).

Hello! I would suggest setting the timings manually to 5-5-5-18 and the dram voltage to 1.8V if it's the default voltage for your memory. Dunno if it really helps in this case but it's still needed later on.

Thx for the suggestion..but unfortunately..it still have the same problem..it will automatically restart

try to loosen your memory timmings, say 6-6-6-18
try set performance level to 8
tRFC to 46

or try rising the DRAM voltage to 1.9v

can you tell us what's the other option, on the item which I bold?

On the 333 B Latch the available DRAM multipliers are 2.00, 2.40, 3.20, and 4.00

okay, you're cool with "2.00"
