Xeon L5639 Overclocking on X58

[YBS1]

I don't think you can kill a Bloomfield.

ROFL...

ive killed 8 C2D Wolfdales, and 5 Yorkies C2Q, and 0 Kentsfield and 0 bloomfields!

Kentsfield + bloomfield was by far intel's most robust tank err cpu..

You have some cold electrons running through your veins, aigomorla.....serial cpu killer.

I almost fried my 5660 with a dyslexic typo - set the voltage to 1.26, except my hand typed 1.62 and set off to stress test. Start running Memtest and see the high temps and voltage and OMG! OMG! Trip over the cats and cords to get to the power switch. Obviously, I don't have the killer instinct. ;-)

 

[Burpo]

Not worried about the SabreTooth, not pushing it that hard. Xeons last with adaptive voltage & good cooling, & if it doesn't..(shrug). I'll get the X5675 and not have to push it as hard..

Can't afford Broadwell-E, but these? pfft..

 

[MongGrel]

Which is why he was known back in the day as the Gulftown Killer. With these cheap Xeons on the loose, it was inevitable that a rash of copycats would appear. ;-)

good lord....

some of your voltages hurt... seriously.. it hurts...

i probably have the best ambient cooling out of all of you, and i refuse to push my voltage past 1.4v for gulftown.

Example of my board setup:
Snip

Infact id much rather have it sit at 1.375 as absolute top, with VTT no higher then 1.3V
due to the fact that i have killed 2 gulftowns already by pushing 1.4V VTT and 1.45Vcore.

Of course they were loaded 100% of the time, which not many of u guys will do, but, non the less ive killed 2.
Also at 1.45-1.5vcore.... the cpu is pushing arround 200-300W.
P/V = A = +/- 137AMPS! :O
Are you guys aware of how much amps that is though your board socket?
The type of mosfets one will require, your boards will not last unless ur running one hell of a beefy board, with awesome cooling on the mosfets.
And im talking about a very durable board...


I hope you guys don't intend to keep that chip longer then 6-8 months, as already im seeing those chips on borrowed time.

Totally agreed boss, my chip has never been over 1.3v not even to boot up to test high clock speeds. Just too much heat and voltage required over 4.2 and for not much of a performance gain. Some people do it cause they like just looking at higher numbers for me its all about the balance.

I don't think you can kill a Bloomfield.

You can but extremely difficult compared to the new chips.

 

[Burpo]

The only numbers I care about are minutes it takes to render. Noisy SOB is sitting next to me, busting out a blu-ray right now. It's an adequate, inexpensive, tool.. nothing more..

 

[BTRY B 529th FA BN]

Now re-run some benchmarks & see how much HT helps 4ghz 12 threads should be similar.

HT on, 4GHz, Ram 1392MHz, 10.22 was my best on 11.5. Cinebench 15 I scored 933 at best :hmm:

 

[BTRY B 529th FA BN]

Don't understand this. Here were my numbers. 4.2GHz @ 1.248v, 183BCLK*4=732, RAM 732*DDR=1464MHz timings 9.9.9.24, thought I would of got a higher score. Did 10.74 with CineBench 11.5

 

[Burpo]

CB displays your chips default multiplier of 21X (look at it's posted Speed 21X183 = 3843). My bclk was higher, 20X200
You would have to set yours @ 190 for 4GHz. The X5675 would be 173 for 4GHZ. Then ALL scores should be comparable.
X5650 = 20x
X5660 = 21x
X5670 = 22x
X5675 = 23X

I want the X5675 because anything above is no longer 95 watts & heat becomes more of a problem

 

[BTRY B 529th FA BN]

Simple, CB displays the chips default multiplier of 21X (look at it's posted Speed 21X183 = 3843). My bclk was higher..

So Cinebench is calculating the frequency and giving the wrong results from what you are saying.

 

[Burpo]

CB displays (from chip info) default multiplier (even if we're above that). Results are accurate, CB displayed speed isn't.
So when CB shows 4GHz on mine (20X200), it's really running at 4400 because I have 22 locked (CPU-Z verified).

 

[BTRY B 529th FA BN]

CB displays (from chip info) default multiplier (even if we're above that). Results are accurate, displayed speed isn't.

Gotcha. Threw me for a loop when you said 4GHz on my chip should produce similar results as yours of 11.22. I would never reference my processor speed from a benchmark that doesn't calculate the actual speed. And I always refer to what the chip will do with all cores loaded, never from the turbo speed which could be on 1 or 2 cores

Average CB 11.5 scores for 4GHz 6c/12t Westmere EP & Gulftown chips are around 10.10-10.22

 

[Burpo]

If you'd set adaptive voltage & up bclk to 190, Cinebench would report you at 4GHz, you'd really be @ 4370 with 23 locked & Your score would be higher. Also, only Westmere EP is 95 watt, not Gulftown. See why I want X5675?

 

[BTRY B 529th FA BN]

If you'd set adaptive voltage & up bclk to 190, Cinebench would report you at 4GHz, you'd really be @ 4370 with 23 locked Your score would be higher.

I was pushing 4.4GHz (192x23) @ 1.3v Cinebench kept crashing
Speed step is enabled
Turbo is disabled
true 4.4GHz

My other voltage settings are on auto. Vcore and DRAM are the only ones that are manual. I am afraid to push the vcore higher because I don't know what the other voltages are adjusting to. There is no way to tell. My EVGA board will give the voltage reading beside the auto reading, column wise.

 

[Burpo]

You would have to up the voltage. That's why I like 95 watt, easier to cool. An X5675 locked @ 25 x 200 = 5GHz would be sweet, & should last a few yrs under water. All you have to do is control temps

 

[BTRY B 529th FA BN]

I have a feeling the chip would be within Intel vcore specs for 4.4GHz but I'm not going to chance it.

The power package reading from CPU id monitor reads 109.23w that's fair enough for me. Wall readings with a Watt reader for the box read @ 177w gaming is around 355w with Rising Storm, UT3, UT4.. perfect spot in the efficiency curve for my PSU

 

[Burpo]

You do realize Gulftowns are 130 watt.. You're not gonna hurt the Xeon @ 130..

What are you trying to say and where are you going with this?

 

[Burpo]

No where.. Run your chip how you want. I do

 

[Burpo]

I played with settings & reached a good compromise @ 195 bclk & +.22 adaptive voltage. Lost a full point off CB, and a minute longer time rendering a dvd, but I guess it will do..

 

[CropDuster]

Burpo, can you post up your BIOS settings? I'd like to try to replicate this.

 

[Burpo]

These are old screenshots & I've dropped cpu voltage from .30 to .22 now..

Also bumped PLL to 1.92 & QPI/DRAM Core Voltage is now 1.32500

 

[getho]

hi folks, spent a couple of days getting into this.

Thats where I'm up to. 2 things:
qpi voltage is 1.325, dram bus volt is 1.64 (its 1.6v ram but running now at 8-8-8-27, 1536mhz)
everything else on auto (except all the speedstep stuff).
there's nothing in those voltages that looks dodgy is there?

2nd thing is under load the multiplier drops to x20, Is this heat related? When I switched speedstep on it wouldn't go passed x20 under any load. - With idle temps of 30-40.

If I could get it running consistently at 4.29Ghz id' be happy

 

[Burpo]

I only see that your multiplier is showing 20 (CPU Ratio = Auto?), where as I set it manually to "22".. I also use "Offset" for CPU voltage control. This saves on the chip & your power bill, rather than have a fixed voltage at all times. BIOS screen shots above your post show settings I use. IIRC, Speedstep & C states has to be on for 22X - 23X Turbo..
Good start tho. Lots of Compute power for little money with these chips..

 

[getho]

Thanks burpo, yes I used your screenshots to check my settings and tweak a few things. I've got a p6td deluxe v1. Its 5 years old, I can't believe I'm getting these speeds from a 5 year old rig! It also means I don't have the offset option.

The multiplier is set to 22 in the bios, and c state and speedstep stuff is off - thats why I'm wondering if its throttling due to temps.

I ran prime95 blend test and it crashed after 2 hours (doh), so I upped the core voltage to 1.31845 and the qpi to 1.33125.

I'm not sure what the IOH and ICH voltages do - so I left them out of the equation for now.

Another weird thing is that the dram voltage steps at .2, so I can either go 1.64 or 1.66 (is this because the ram is rated at 1.6 not 1.65v?)

EDIT: Arse: just been reading about turbo throttling on the p6td deluxe. Apparently you can cross-flash the bios with the p6t bios, but that would mean replacing my current bios from 2010 with one from 2009 - scary (http://www.xtremesystems.org/forums/showthread.php?210480-Asus-P6T-Deluxe-Discussion-Thread/page74)
