Overclocking E4300 on Asus P5B (some issues)

post #1 of 23
Thread Starter 
Hello!
Alright, so I have a Core 2 Duo E4300 and a p5b mobo.
I've read various tutorials how to overclock the CPU and have managed to overclock my C2D from 1.8GHz to 2.34GHz (raised the FSB from 200 to 260).
As far as I know (at least on this mobo), when I'm overclocking the CPU, the RAM overclocks aswell.
So at first I set my DRAM Frequency to DDR2-800. With this setting, I could raise my FSB to 240. When I tried to save my bios with FSB set to 260, my rig won't boot up, no post screen, the screen was just black. When I set it to Auto, my rig would boot without problems.
I thought that the cause for this would probably be the ram, as I think that it has exceeded beyond its 800mhz limit.
My memory: GEIL 2GB DDR2-800.
With DRAM Frequency set to auto, I could overclock my FSB to 260 without any problems. But I don't know whether it's safe for my memory to further overclock my CPU.
Is there anything that can be done about it, or do I need better RAM?
By the way, you can find my system specs in my profile.

What is the voltage on the memory. Try putting the ram to 2.1v and set DRAM to FSB ratio to 1:1. This will be a lot easier on the ram. So when the FSB is at 260 the ram has a rated speed of 520mhz.

I'll post some screens of my bios and voltages:





Some info in Speedfan:



PCProbe:



And this is my RAM:

http://www.geilusa.com/products/showSpec/id/54

Specs:

Code:
*  Available in 1GB Dual Channel Kit (512MB X 2) Sku# GX21GB8000DCK, 2GB Dual Channel Kit  (1GB X 2) Sku# GX22GB8000DCK
    * Working Voltage : 1.9-2.3V
    * 240pin, Un-buffered DDR2 DIMM
    * Metallic Aluminum Heat Spreader
    * Retail Package
    * Life Time Warranty
As you can see, the working voltage is 1.9V-2.3V

One more question. Can I change my RAM Voltage to 2.1V in one step immediately, or should I go step by step until I reach that value? I don't want to fry my RAMs.

u set ur timing in the bios by accessing adv options
in gigabyte boards i access the adv option by clicking CTRL+F1
u should read ur board menual on how to access the adv option

You mean the RAM timings?
Yes, I have these options under Advanced > Chipset > Configure DRAM timing by SPD. When I set it to manual, I get these options:

DRAM CAS# Latency [5] - configuration options:
3, 4, 5, 6

DRAM RAS# to CAS# Delay [6 DRAM Clocks] - configuration options:
2-6 DRAM Clocks

DRAM RAS# Precharge [6 DRAM Clocks] - configuration options:
2-6 DRAM Clocks

DRAM RAS# Activate to Precha [15 DRAM Clocks] - configuration options:
4-18 DRAM Clocks

Took that straight from the manual. Any ideas what to do?

yes put them on stok and lower ur ram multi as low as u can so u wont go pass the stock MHZ
then u should be able to OC ur cpu higher

Yea ok but could you please tell me which options I should change?
Sorry, but I'm a newbie to that OC stuff.
By the way, I have lowered the FSB from 260 to 240, because my PC froze while listening to music/playing games. It works fine now. Is the RAM the cause of the crashes?

find out with everest the normal timing for ur ram and set them in bios (manualy)
after every FSB change run PRIME95 for stress test to see how stable ur system is
while jumping run it for 20min after each jump
when reach final destination run it for at least 12 hourse
if it crash freez or what ever mean somthing dosnt get enought voltage ,uselly its the cpu so rise it by 1 forword and test again untill it stable ,dosnt go over 1.45 voltage not recommanded
dont jump too high for it will increas ur system heat
