Disable it as on my board it caused me issues with it turned on. It trys to make up for Vdroop by pumping a little more voltage into it to keep it closer to what you set it as "the core voltage I am refering to BTW". I have it enabled for my Q9450 and it likes it but, I have noticed a decent amount of people saying it causes issues with their Core 2s and I had an issue as well so.. disabled.

Both if you have both,, Disable everything you don't need under the CPU advancd options or whatever it is called on your board until you get stable then see what you can get away with. May be you can use speed step but, get everything stable first. I personaly leave all that crap turned off but, I don't care about the enviorment so.. :p:.

you have to go into the CPU settings screen and disable everything there. Not the same window you OC in.

E8400 E0 Q827A345 vid 1.26

I need Loadline Calibration ON, it's the only way i can get my system stable @4.5Ghz on air. Shame it needs 1.45v for it.... :shakes:

My settings are:
Ratio CMOS Setting : 9
FSB Frequency : 500
FSB Strap to North Bridge : 400
PCI-E Frequency: 110
DRAM Frequency: DDR2-1000
DRAM Command Rate : 2T
DRAM Timing Control: Manual
CAS# Latency : 5
RAS# to CAS# Delay : 5
RAS# Precharge : 5
RAS# ActivateTime : 18
RAS# to RAS# Delay : AUTO
Row Refresh Cycle Time : AUTO
Write Recovery Time : AUTO
Read to Precharge Time : AUTO

DRAM Static Read Control: disabled
Ai Clock Twister : light
Transaction Booster : auto (0-30 I still dont get this setting, there is NO relax)

CPU Voltage : 1.46//reads in BIOS/cpuz/cpuid: 1.448v
CPU PLL Voltage : 1.58 // 1.664v
North Bridge Voltage : 1. 65 // 1.648v
DRAM Voltage : 2.2// 2.2v
FSB Termination Voltage : 1.44// 1.344v
South Bridge Voltage : AUTO
Loadline Calibration : Enabled
CPU GTL Reference : 0.62*
North Bridge GTL Reference : 0.67*
DDR2 Channel A REF Voltage : AUTO
DDR2 Channel B REF Voltage : AUTO
DDR2 Controller REF Voltage : AUTO
SB 1.5V Voltage : AUTO

CPU Spread Spectrum : Disabled
PCIE Spread Spectrum : Disabled

Gonna try Intels burn test now...

EDIT:This app is very scary, it took my cpu from 36 degrees up to 68 Degrees C in 1 second! I dont think this represents normal use, even with several stress tests the system never reach beyond 59 degrees..
My cpu is rated for 74Degrees max according to Intel, whats a safe max temp to run on? (I did pass the Burn tests)

Thanks again for assisting me

Then you need face the truth and lower your clock maybe try 4.2Ghz or 4.3Ghz
whit better volts, if that makes you feel pleased.

And keep tha LLC enabled, its really great option......

Well about temps, Intelburner states that it takes temps +20c upper than other stress programms. I have always tried to keep intelburner stable on 60-65c Temps.

:eek:

1.45v on air? Wow lol, i'm sure that cpu won't last too long!

Ya i hear you shouldn't give them more than 1.3625.. lol but I'm sure you already knew that. I'm not sure if I wanna go above it either. I have not yet. but I will once I go water.. but I have a Quad. not a e8 series. I'm just lookin through the thread cuz I want a e8500 for my other machine.

Okay Guys some help here

sSpec Number SLB9K

E8500 Q822A537 Pack Date 8/7/07

any good ? I see its not on the list :shrug:

is it E0 stepping. I didn't know the e8500's had E0 out yet.. thats great. the fact that it is a E0 stepping I'm SURE you could get to 4.5 Ghz on Air.. perfectly fine.. or higher. the E0's are great grreat overclockers. Where did you get it.

also the Q8 means it was made in 2008, 22 means the 22nd week of the year.. so Middle of May 2008. and A is where on the Wafer it was cut from. I'm sure it will work fine. All the E0's seem to be very good, and very stable.

Good Luck!

I wouldn't say all e8500 E0 do 4.5 on air. I been thru 3 of them and none of them are primestable at 4.5v on air. More like 4.3-4.4 on air. My current one is 4.313 on air with 1.32v 8hr+ prime small fft stable..

Week 22 E0 E8500's tend to be great! They seem to correlate with their respective e8600 fpo/batch number performance.

2 good q822 e8500 E0 clockers on air:

1) Q822A553 4.4ghz 1.328v, 4.5ghz 1.36v
http://i246.photobucket.com/albums/g...e8500ds3lB.jpg
http://i246.photobucket.com/albums/g...e8500ds3lA.jpg
2) Q822A549 4.5ghz 1.3v.

cAN YOU PLEASE give out your setting you used to get a 8500 @ 4.1 4.2 4.3 or 4.4

I have a Water Cooled E8500 C0 at 4.15ghz right now and i can't get it stable any higher
want to know what settings everyone else is running

I have PC8500 4 gigs of ram, what memory timing should i be running is 2.1 volt overkill

Just want some settings to test thanks

A lot of C0's max out at 4.0-4.2ghz under reasonable voltage (1.4v or less).

It's either your cpu, ram, or northbridge.
Put ram on 1:1 instead of 5:6 and northbridge 1.2-1.3 and give it a go on prime or orthos blend.
With ram at 1:1 you can rule it out and focus on your cpu or northbridge.
Make sure your northbridge isn't getting too hot either.
Of course turn off eist and lock pci-e to 100.
