**Official e8400/e8500 Retail OC Thread

[carepolice]

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....

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.

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

[xguntherc]

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.

[DOM.]

Okay Guys some help here

sSpec Number SLB9K


E8500 Q822A537 Pack Date 8/7/07

any good ? I see its not on the list

[xguntherc]

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!

[HDCHOPPER]

by & large 822's are good clockers

well idk what you just said lol but I know its a E0's and are good ocers but wanted to know on the Q822A537

by & large 822's are good clockers

so there good or good good

also its sSpec Number SLB9K forgot the K

[Peter949]

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..

its wouldnt be on water dtec and GTX480 rad

Here is E8500 Q822A544 - I run 4512 @ 1.37v 24/7 tho. Load is 52 ish.

My new settings:

thanks just wish i didnt have to pay 15.69 more for it :p

also my E8500 and what Motherboard ? thread let me know what you think

[LagunaX]

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


2) Q822A549 4.5ghz 1.3v.


For more details see my sig =)

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

And a Custom Water Cooled kit so temps are always low

[LagunaX]

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

[Quad-Damage]

maxed out you think?

Water cooled

I keep crashing out in games, 10x00101 read errors

Damn ati drivers

[Quad-Damage]

This might be why, what should i change?

[LagunaX]

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.

[rurik]

This might be why, what should i change?

I think, your chip need more voltage

[Yozzman]

My contribution...
E8400 C0...

4.67ghz...
And no sub10 superpi
Need more tweaks :P

[JCGhz]

Just got this one..

[kaskuli]

ram timings?

[ssabripo]

Guys,
I've gotten my system stable with:

446 x 9 = 4015 Mhhz
Vcore = 1.2875
Vnb = 1.30

System is very cool and stable. I tried going to 466 fsb (~ 4.1ghz), and did not run stable, so I assume I need more Vnb and Vcore. I dont think the extra speed is worth the power/temp increase, so now I want to reign the cores and temps down as low as possible.

I noticed several E0's running 1.1-1.2 Vcore...I'm gonna see how mine does there. My question is, how low can I safely go with the Vnb? can I get away with 1.2v?

[carepolice]

low
safely
Vnb?

Umm there is no danger using low volts...

1.3 Is pretty high (lol, high and high ), depends how many stick of ram you got there

I belive that you will find nice spot in 1.16-1.26 area

Just looked on you sig and noticed 4x1GB, it may need higher nb on some situations
