Retail E8600 Overclock, Temps, Settings Thread

[fps_dean]

That's a lot of volts for 4500 spi. I thought these were supposed to be stable for 4500mhz 24/7 at around 1.33v or so. Yours has an unusually high VID too... that makes it a cool chip to run though.

Test some OCCT / prime when you have the time.

I'm failing Orthos at 1.355 volts myself, but I think I might be doing something wrong. I did hear about 1.30v but I thought that was an anomaly too... 1.33-1.35v does seem quite normal.

This settings seems fine, unless you should be able to use “strong” with that divider and fsb I´m not sure why yours e8600 can´t go higher. If it helps this are the settings I use for the 3/4 divider and the e8600 at 4260mhz:

10*426
400strap
ram 1136mhz
dram static read control: enabled
ai clock twister: strong
transaction booster: enabled
relax level: 0
nb: 1,33v



The max fsb this cpu reach with this p5e is 467 at 4200mhz with those settings:

9*467
333strap
ram 1120mhz
dram static read control: disabled
ai clock twister: strong
transaction booster: disabled
relax level: 0
nb: 1,65v



Note that I have only two sticks, if you have 4 the limit could be aprox 450fsb.

Thanks you solved my problem. I disabled Transaction Booster and the all is well. I can now go up to 10X440 with a 333 fsb strap. I can go much farther but it require too much Vcore for my taste. We have the identical settings but my Vcore is higher at 4.4 gig. Yes, I do have 4 1gig sticks.

Thanks for the help! I tested to lower the CPU to 7X and then I could run 540FSB (1080 memory) but not more.
I guess my 1066MHz memory does not work at higher speed. Maybe a volt increasement to 2.2V would help...

But could my E8600 be defective? It does not respond better to a volt increasement. Higher then 1.5V is a no no!

Still 540x10 or 540x9.5 or 540x9 would be better then my 7x now...

What is the voltage requirement for your CPU at 7X ? if it's already pretty high... you can be sure it will need 1.5 and more for those speeds you want, your watercooling prolly doesn't cut it...(what are ya temps ?) And it still could be a bios flaw or setting you overlooked...

why don't you use 500FSB and try to stabilize 8X... then 8.5 and hopefully 9 multi stable... more prolly needs advanced cooling

Another EP45 user told me this morning that he was obliged to let the vFSB on auto to go higher. You could try this mate


P.S: And it is very risky to let your Vcore above 1.3 in everyday use.

I keep my voltage at standard for the 7X, I think it's 1.25V, but I am not 100% sure..(at work now)
8.5 and 9 does not work. 8 works too. It's strange that my water cooling system does not do the work. I have 30 degrees on my NB and 45 on CPU. I have seen people getting 10x500 with air so I am very dissapointed on either the water cooling or the CPU.

I will try vFSB higer voltage tonight.

"P.S: And it is very risky to let your Vcore above 1.3 in everyday use."



I think not so risky....several folks have mentioned vCore 1.4v as the level to stay away from as well as higher vFSB (1.24+) for EO stepping dual core.

I can now go up to 10X440 with a 333 fsb strap.

Great news! Enjoy it

That E8600 looks great but 2 expensive ,and I dont have any money left because I spend all of my money to skulltrail

expensive? e8400 is your choice

it my friend's result in Thailand.

Today I got my Q820A606. For now nothing special, but not to bat either (first run- 4.5 at 1.4V real, stable (Im sure Ill get it bit higher too) I can do 3Dmark01 on 4650 at 1.4V, and the price 180€ was great, so im happy

What are your max 3dmark clocks on safe voltages?

[CCC]

But could my E8600 be defective? It does not respond better to a volt increasement. Higher then 1.5V is a no no!

some chips can only run said vcore if the temp given to the core is so and so

Ive used many e8600's some will not even take 1.4v on air cooling 'as in set higher and it will no post/shut down' but when these chips have touched ln2 the colder the pot got the higher the vcore i could add

so becasue the chip/board doesnt work on air/water doesnt mean its bad if you need more than 1.5v I hope oyur tring to run subzero, but defective chip no way defective would be 333x10@1.1v not working

hope this helps

These will be my 24/7 GAMING system settings.
All details in signature.

Voltages on bios are ALL DEFAULT, excepting Vcore set at 1,31250 volts in bios, and VDram set 1,90856 volts, also in bios..
Loadline calibration is on auto, all other settings untouched.

Booted exactly like on printscreen, FSB 525.
I must to go to MONOCROME printscreens , because restrictions of 200 kb attachments...

My humble contribution to the thread

E8600 Q820A604
9 x 480 4320 MHz 1.328v under load
2 x 2 GB OCZ Reaper 14400 @ ddr3 1600 7-6-6-24 1T 400/1333
TRUE120 lapped w/mx-2



3D bench with 2 x Diamond XOC Black 800/1100 CF



If I drop even one notch on the vcore it fails occt in 15 min or less. Temps get to 60C at load, so probably not too much more headroom unless I decide to go with water for a 24/7 OC.

[giorgos th.]

cpu at -52C (SS),NB @ 1.82Vmch at ~50C aircooled...
searching for max fsb,and then will begin testing on the Rampage xtreme..

P5Q Deluxe, stock cooler for motherboard, CPU under water

[firebane]

Anyone finding with these chips you'll get a BSOD with a Machine_Exception_Check?

Mine is stable at 4.6ghz but anything past that and I start getting those MEC BSODs.

BSOD's here also when trying to find max benchable clocks . I tried about 4 E8600's and all do the same .

[redrumy3]

quick question just picked up a E8600 E0 whats highest safest volts for air (Tuniq Tower) to go? staying under 1.4v? going to be for a friend so im overclocking for him

Yah my first 2 8600s I had wouldn't do much more than 4.5ghz and the one i have now does 4.6

[Grnfinger]

Couple of quick runs

[M-XXXX]

On water and P5Q Deluxe

[HDCHOPPER]

5.0 with chiller or water that would be allright

[Grnfinger]

If I have a stuck senor is that grounds for RMA?
And who do I return it to, PC store or Intel.
Store policy is 90 days first 15 direct replacement, missed the first 15 deadline but I'm well within 90 days.

[wilson]

One of my cores is stuck at 37 but when above this it works and this has happened on two of my e8600 but they are both good overclockers so im gonna keep mine.

1.40v should be fine. I won't take mine past 1.40v, but many people say 1.45v is OK. There really is no guaranteed "safe" voltage, it's not possible to put a number on it. Intel state 1.3625 as an absolute max.
