Hi

 

I NEED HELP! Can you help me overclock my system.

 

 

It is:

 

mobo: ASUS P5KC (bios 1001)

CPU: C2Q 6600 G0 + FREEZER PRO7

RAM: Corsair TWIN2X2048-8500C5D

Power Supply: Corsair HX520W

Case: Antec P182

 

I want to OC it to 3Ghz (FSB 333) with the RAM at 1066Mhz (5.5.5.15).

 

 

any help is welcome.

Download memtest from
and extract the ISO image. Burn the ISO image to an CD-ROM disk.

Download CPU-z from
and post screen shots of your CPU/Memory/SPD tabs after the overclock.

Download Prime95 (OS: 9x/Me/NT/2k/XP) --->

Download Prime95 (OS: XP x64/2003 x64) --->

Download Core Temp

Download OCCT Perestroika for a quick, hard and fast CPU stability test. Download

 

Enter your BIOS and set:

 

JumperFree Configuration Settings

 

Ai Overclocking = Manual

 

CPU Ratio = Manual

Ratio CMOS Setting = 9

FSB Frequency = 333

PCI-E Frequency = 100

DRAM Frequency = DDR2-1066

DRAM Timing Control = Manual

CAS# Latency: 5

RAS# to CAS# Delay: 5

RAS# Precharge: 5

RAS# Activate to Precharge: 15

TWR= Auto

TRFC = Auto

TWTR = Auto

TRRD = Auto

TRTP = Auto

DRAM Static Read Control = Auto

DRAM Dynamic Write Control = Auto

Transaction Booster = Disabled

Clock Over-Charging Mode = Auto

CPU Spread Spectrum = Disabled

PCIE Spread Spectrum = Disabled

 

Voltages

 

CPU Voltage = 1.38v

CPU Voltage Reference = Auto

CPU Voltage Damper = Enabled

CPU PLL = Auto

DRAM Voltage = 2.2v (for Version 1.xx) or 2.1v (for Version 2.xx+)

FSB Termination Voltage = Auto

North Bridge Voltage = 1.4v

North Bridge Reference = Auto

 

Boot to the Memtest CD and allow for two full passes. If stable on the memory, then enter Windows and run OCCT for the 30 minute stability test. Run Core Temp to view your temperatures during OCCT.

 

Results?

it did not pass the memtest at 1066 :sigh!:

it showed me errors at the bigining of the test.

i sat the FSB back to 266 and ran the test with RAM at 1066 and it didnt pass eather!!!

i thought that the RAM got deffect, but i sat all to auto and ran the memtest and all went ok.

so i think i can execlud the RAM from bing deffect or what do you think?

 

i made it all as you said in the bios. but there is no CPU Voltage Damper option.

 

am i missing somthing?

did my mobo new bios(v.1001) is the cause?

i was allways running the RAM on 1066 at FSB 266. but now it wont go!

 

:(:

Flashing to new BIOS's can easily be problematic. The P5KC board is also a bit of a problem due to the DDR2/DDR3 Hybrid design. You may have to tweak and test to find out. Often it isn't as easy as asking someone to give you the values, setting them in and getting stability. You need to learn this yourself. Set the DRAM to 800Mhz and the FSB to 333Mhz.

 

Post your CPU/Memory and SPD tabs.

 

Then try 400/1066 with an 8X multi. Some do better with that and the P5KC board than 333/1066 and 9X.

Ok, done testing on FSB 333 and RAM at 800 and all went fine.

i also tested FSB 313 and RAM 1001 and is was ok too.

 

the FSB 400 and 1066RAM was not ok at memtest. same as 333 and 1066.

 

i even tested 266 and 1066 and it didnt work too!

 

dose that mean that the new bios is the cause of this problems, since the older one had no prob. with 1066 at least at 266 FSB?

 

ASUS forum is not so informative as this one, all ar just costumers and no admin. is replying to and post.

 

I know i have to learn it by my self, bu what is the point in only reading and not ask questions to people with experience.

 

 

thanx for your support.

Asking questions is good. You just have to ask and then tweak. Then you try some tweaks on your own. You read what others have done and you tweak again. In time you will become more adept at finding out what works with your current hardware.

 

So now, set your timings to 4-4-4-10, and Memtest. 800Mhz with 4-4-4-10 is very close in bandwidth to 1066Mhz and 5-5-5-15. Then with the next BIOS you can try again. :)

i did somthing els and i think it was the wright choise.

I dongraded my bios to the brevius version (v.0903). I had no probs. with this one befor.

I ran the memtest at FSB266 and RAM at 1066 (5.5.5.15.5) and it passed, so i went back to the bios and seted FSB at 333 and ocours the voltages you gave me erlier and the RAM the same as befor at 1066 and ran the memtest end it passed 3 times.

 

then i started the CPU test using prime95 for 1 hr and counting as i write, al temps ar study at ca. 60. but the v.core i- obviusly- is suffering from a huge drop at zcpu.

so i think to bypass this i have to pincel it. but is it safe? am i going to void the waranty of the mobo if i do it?

 

i hope you see this results ok, unless there is somthing i missed.

 

thanx

Vdroop modification will not void the warranty. I would personally remove the system from the case to perform the pencil modification. You will then need less voltage to run your overclock, but even so, a 60C full load is fine. More than fine.
