E0 Stepping clocking results collection (Q9650, E8600 etc)

[nevbie]

E0 steppings only. If you are unsure about your processor stepping, check it from CPU-Z.

It doesn't have to be an overclocking result. You could post that your E0 E8600 will run stability test X @ some lower voltage @ some clockspeed. The results where it's almost stable are the most interesting ones.

IntelBurnTest is recommended as the heaviest stability test: http://www.ultimate-filez.com/...dex.php?showtopic=3441 (And maximum stress option in it - should provide you with the highest temperatures)

Post the vcore reading you see in CPU-Z while the specified stability test is running. If you cannot get so far, then don't post that result. Do not post the BIOS voltage setting.

For example, booting successfully to Windows XP is a *valid* stability test, if you can get the vcore reading from the CPU-Z without crashing. But it only makes sense to post this if you cannot do much else.

Basically, you can give a data point by posting the following information (more than one data point in one post is OK too):

---

Model:
Vcore:
Speed:
Stability:

---

Some imaginary examples how it would look like:

Model: Q9650
Vcore: 1.128
Speed: 9*390=3510
Stability: Pass IntelBurnTest at stress level 3. Took 20 minutes.


Model: E8600
Vcore: 1.008
Speed: 3350MHz
Stability: Passed 40 minutes of prime95 small FFTs, then failed.


Model: E8600
Vcore: 0.989
Speed: 3350MHz
Stability: Boot to Vista, BSOD when closing CPU-Z.

[aigomorla]

i'll keep out of this one seeing how there all ES's. :X

 

[BTRY B 529th FA BN]

I'm in. I am waiting to install my Q9650 E0 stepping. It'll be a while but I'll have results no matter

 

[GarfieldtheCat]

Currently:

e8600
1.376V
4.3Ghz (430x10)
8 hours Prime95 small FFT stable

Still tweaking, so it's in progress.

 

[warbean]

I'll bite.

e8600
1.328V
4.1 Ghz (410 x 10)

9 hours Prime small FFT stable.

Probably can do more but am happy now.

 

[rgallant]

not many takers on this but I'll add mine so far -still testing



-model = E8600
-Vore bios = 1.325v
-cpu-z146.5 = 1.232-1.235v

speed : [10x] 4.20 & 4.21

stability : passed ,default 1hr. OCCT, orthos small ftt 40mins. 3d06 , vantage , crysis benchmark , super pi 1m = 11.146
:failed @ 4.3 with same vcore

420 and 421 FSB with default multiplier?
1.232 vcore in CPU-Z while ..which program running?
Failed how?

It's too unclear to add! Just one model&vcore&speed&stability test at once. And if you fail to boot to OS, it isn't as useful, because we don't know the voltage under load.

 

[Tempered81]

hes saying 4200mhz @ 1.232v load. 1 hr OCCT.

 

[Link]

Q9650
1.27v @ load
3825mhz(450x8.5)
2 hr OCCT

 

[nevbie]

Any more E0's now?

Here's mine, preliminary (have to do another cooler swap or small mod to break 4 GHz):

E8600
1.24 at load, 1.325 in BIOS
3901 MHz (10x390)
1 Hr+ OCCT
2 Hrs. Orthos Prime Blend (all I had time for at present)

System runs at 70C-71C under load (if the numbers can be believed from Hardware Monitor Pro) so I need to get that under better control. No crashes in either program up to now.

 

[Saga]

E8600
eVGA 790i
1.256 vcore
4250mhz (10x425)
4 hour prime blend (currently running)

This was just the first oddball number I picked. Will see how close to 4.5 I can get on the tiny little stock cooler after this prime passes the 12 hour mark.

Using two sticks of OCZ's 2000mhz DDR3 at 2200 too so I'm happy. :thumbsup:

 

[Saga]

Bumped things down a bit. Running 4.2ghz @ 1.15v happily, but appear to have some heating issues.

Right now I idle at 42 and sit around 65 at load. When I had it running at 4.5 @ 1.25 it was idling at 50 and sitting at 95 under load. :Q I definitely need to replace this dinky little heatsink it comes with.. might just jack the one from my I8500. Anyone have any other oem replacements where I don't have to add a backplate?

 

[soccerballtux]

wow, stock heatsink and you can get 4.2 That's insane.

I can get 4.5 probably, but my temps would be running dangerously high on load due to having to bump to 1.25-1.3 volts.

Really this boils down to the stock cooler being EXTREMELY small. I mean it's literally 1/3rd the size of the stock cooler that came with my I8500 - which makes me wonder how high I could go on the 8500 oem cooler.

I know most computer stores around here sell an OEM replacement cooler that is identical to the 8500 cooler with a pure copper base for like $6.. so for $6 I could upgrade the cooler and probably get 4.5 stable on air.

This processor has been the first one to impress me in years. :thumbsup:

E8400 E0
Abit IP35-Pro w/ BIOS 17

Bench settings:

533x9 = 4.8Ghz
vcore = 1.47v
vtt = 1.30v
vmch = 1.64v

Stable enough for wPrime 1024M. I don't bother with Orthos or Prime because there have been too many situations where I've been stable for hours with those programs and then it can't complete wPrime 1024M or SP 32M.

My 24/7 settings:

518x9 = 4.65ghz
vcore = 1.4v
vtt = 1.2v
vmch = 1.48v

 

[Saga]

Small update, was able to successfully run for the last 18 hours on the stock cooler - 4.4ghz @ 1.24v. Idle temp 44 load 75.

 

[Tempered81]

4.65ghz, not bad! I was hoping for 4.7 out of an E8600 for 24/7

 

[Dadofamunky]

Dqniel, what cooling are you using???

Revised report:

E8600@4.05 GHz
10x405
1.330V, 1.24V/63C under load, 43C idle
OCCT 1 Hr.+
wPrime 1024 test completed 591 sec.
wPrime 32M speed test completed 18.48 sec.

No 4.5 GHz for me, I'm using microATX and my cooling options are limited unless I go water.

Overnight Orthos test next. Things are looking much better with a better cooler. My temps may also be a bit high since it's 100 degrees in Northern California.

Woo hoo! First 4 GHz system I've ever had!

Have you tried Linpack (or intelburntest as a frontend to it)?

24/7 is too vague. I'll add it if you specify some kind of stability test and if you do, please specify the vcore you get when that particular stability test loads the cpu.

That's 18 hours of prime blend, right?

 

[Emo]

E8400 E0
vcore 1.35 in bios, 1.32 idle CPU-z, 1.31 load

4230Mhz (9x470). Have tested it to 9x480 but I had to bump the vcore up a notch. Passed linpack on max load, 1hr+ OCCT, orthos, various other programs.
The only drawback is that I can't run it with 4gb ram on my P5B Deluxe. Any ideas?

Correct, 22 hours approx before I turned it off. I'm relatively comfortable with that overclock at such a low voltage, however I'd be dubious about doing it 24/7 on the stock cooler as 75 load (I run load often and for very long periods of time) is a bit higher than I'm usually comfortable with. I tend to cap out in the 65 range, so this still calls for a better cooling solution in the long term.

What HSF?

 

[dqniel]

I'm just showing what I run it at and it works for my needs (Photoshop, Internet browsing, benchmarking SuperPi and wPrime, other basic Windows tasks). I'm not going to waste my time and effort running an arbitrary stability program... no offense, but those programs are good for one thing- a false sense of stability. If your computer works without a hitch for what you need it for, then it's stable. I've had CPUs in the past, back before I learned the uselessness of "stability" testers, that were 8 hour Prime95/Orthos stable but then crashed within minutes of running Oblivion or CS:S. Also, they couldn't pass wPrime 1024.

By 24/7 I meant what settings I use to keep my computer running 24 hours a day, 7 days a week to run the programs I use on a daily basis. I guess you could say it's Photoshop stable? lol. That's probably the most demanding thing I use on a day to day basis. The voltage displayed by CPU-Z while Photoshop is loading or applying filters is 1.38v. 512x9

I went from 518x9 to 512x9 because I wanted to use a quieter setting on my P182 exhaust fans while still keeping the load temperatures under 55c.

TRUE w/ S-flex low cfm. I can't remember which exact model it is, but it hardly pushes any air. All inside my near-silent P182.
