E6750 Retail - Some results Air Cooled

[MacClipper]

Borrowed the title from Pedro's E6850 thread, makes for much neater title listing formatting, don't you think... hee hee.

Just got it today and I am already impressed. Amazing how low temps are reported at idle. FYI, ambient local temps here hover around mid-20Cs so these temps kind of incredibly low but my finger does confirm the HS is totally cool though. Started with my high rpm fans, threw them out after a few minutes for peace and quiet since there's totally no need for them, nice.


3.6GHz at just 1.40v BIOS!


Probably needs loads more vcore to from here cos I did try pushing up to 1.5v BIOS at 3.8GHz (475FSB) but it's still no good after just a few minutes of Orthos.

nice results.

got 1 of these ordered so be interested to see how far you can push yours.

[msgclb]

My bank account is empty! My credit cards are maxed out! Guess what I ordered? Yes, I've ordered an E6750 since I couldn't squeeze another $100 for an E6850. So keep pushing it so I've got a target to shoot for.

Nice results, can't wait to get mine! If I can run it at 3,5+ 24/7, with the Ultra120 Extreme, I'll be satisfied.

[MacClipper]

Anyone knows why the G0 stepping makes so much of a difference in temps? Just yesterday I was stress testing my old E6300@3.3GHz 1.45v same rig, it idled at 50C and was really cooking at 70C doing Orthos.

Not complaining cos I am really loving it esp. the silence.

[MacClipper]

Just realised that I was trying higher with 4 sticks of RAM, think got to cut down to 2 sticks later so to eliminate the mobo NB quality factor. lol

Nice, now all we need is an E6550 Retail - Some results Air Cooled thread Can we get some temps of CoreTemp @ those 1.4v?

I've been wondering the same thing. I searched the Intel web pages but couldn't find anything on these new G0 chips. In reading a couple of reviews of the E6750 I noticed that they don't mention anything about the cpu temperature.

The one thing I did notice was the voltage...

CPU-Z E6750
Voltage: 1.040v
Core Speed: 2666.7 MHz
Multi: x8
Bus Speed: 333.3 MHz

CPU-Z E6750
Voltage: 1.200v
Core Speed: 3920.2 MHz
Multi: x8
Bus Speed: 490.0 MHz
(not quite stable)

CPU-Z E6750
Voltage: 1.200v
Core Speed: 3840.1 MHz
Multi: x8
Bus Speed: 480.0 MHz

Other reviews showed the CPU-Z voltage ...
1.328v with 1.3875v in BIOS @ 333.3MHz FSB
1.238v @ 333.3MHz FSB
1.408v @ 445.0MHz FSB

MacClipper, what is the stock voltage shown on the package, etc.?

[adamsleath]

these chips are so coool....literally
my idle coretemp @ 20c ambient is 12c (dodgy coretemp reading) @3.6GHz @1.36v 6850.
dual orthos .05 droop 33c max under load @ 20 minutes dual orthos.
@3.4GHz 1.3v is dual orthos stable.
@3.33GHz this one is fine at 1.24v...havent tried lower volts yet.

Im waiting for mine to come in, stupid slow shipment from etech4sale

[adamsleath]

hopefully there are some golden 6550's out there...but with 7x multi youll need a good mobo.....530x7???

[Gepidae]

Yup I plan for the IP35 so I hope to push it to around 3.6

I got mine last week too...

Been playing for a few days now, having some board trouble yet.

My computer room is ambient ~25celcius and my E6750 @ stock settings runs 15celcius idle, with the stock boxed cooler!

I ran orthos for 8 hours on stock boxed cooler and cpu maxed out @ 47celcius.



I have a ZALMAN CNPS-9500-LED now, and while running orthos I max out at about 32celcius now.

Gotta get this board figured out and overclock the snot out of it!

hey guys, don't get too excited about temps just yet. CoreTemp is clearly not calculating temps correctly on the G0 rev chips. idling 10C below ambient isn't just impossible, its 10C past impossible. i think it is almost safe to say that 15~20C should be added to CoreTemp readings for actual temps...just an estimate based on the results users have posted in this thread.

[MacClipper]

It's definitely cooler than the older steppings, I dunno exactly how much though the digital index (aka my index finger) confirms it is way cool. And you should see the even lower incredible CPU temps in the Asus 1302 BIOS... lol

SuperPi 1M, got to read up on tweaking the subtimings soon.

my BIOS hardware monitor temp shows cpu at 26c
ctemp shows 15c...so maybe 10-15c difference between ctemp and actual...

[MacClipper]

Tech Reports on power consumption of their ES E6750 test rig for what it is worth, doesn't give any clue to the incredible low temps we are seeing around here in the retail chips. Don't think they mentioned any temps too.

[adamsleath]

anyway i can tell by touching the heatsink base that it's cool
we wont know until someone puts a thermistor on it.

I was going to say the same thing. The chip CAN NOT run cooler then ambient temps if your running it on AIR. It' just not possible. However even with +10C they are looking good. Hopefully with the new chips we all get flat IHS's!

[XtremeTiramisu]

I don't mean to brag or anything but I'm seriously going to buy either E6850 or Q6600 G0 on/after July 22nd. However I'm leaning a bit more towards the E6850 since it'll run cooler than Q6600 G0 becouse I'm on air (check my sig).
My E6700 is my 3rd C2D this year and its VID is 1.2500v and at stock voltage it could get Orthos stable up to around 3.33ghz!
At 3.6Ghz like you, I was using roughly the same voltage, 1.38v or less
at 3.73Ghz, I can get it stable with only ~1.42v under load.
Thanks to P5K-Dlx's "voltage damper" so I only have very little vdroop.

I'm expecting the E6850/E6750 to do much better than my current semi-golden E6700, I hope..

[GripS]

NICE!!

I'm curious about your screenshot tho.

It shows 4660mhz in your orthos screen. But in your CPU-Z screen it shows 3728...... What gives?

This is a very common question and I'll elaborate again
Keep in mind that my E6700 has a stock multiplier of x10
Orthos is only capable of recognizing the stock x10 multiplier times your current FSB so in this case x10 multi x 466 = 4660 which is obvious no way in hell possible on air even in 2020 lol...or maybe I'm wrong..

[GripS]

Makes sense.

Um, sure it is... At stock settings the cpu drops to 6x multiplier (6x333=2000) instead of 8x333 @ 2666MHz, and not only that - the Vcore drops from 1.35vcore to a bout 1.1v

On top of that, I have a laser temperature gun, I'm not using CoreTemp. I'm using Intel's Thermal Analysis Tool to report temperatures. At first I did not believe reporting 15celcius either... But first I touched the heatsink... It was COLD! Then I used the laser temperature gun to test the temperature of the heatsink, it was also below ambient.

If your bedroom is 25celcius, and you pickup say a metal screwdriver, it will be colder than ambient... Where maybe a spindle of cd's or a stack of paper will be the same warm as the rest of the room.

ANYWAYS... I have some early results with my new system, just started out very easy... Went to bios, disable C1E @ Speedstep (EIST) and then changed my VDIMM from stock 1.8v to 2.2v which is what my new Patriot memories claim to need. I left Vcore @ stock 1.35v (reports 1.32-1.33 in windows) and raised to FSB up to 400MHz.

Seems easily stable at this speed, and temperatures are still amazing me after HOURS of orthos, not even breaking a sweat.

Looks good so far, and I presume that you're using the Zalman 9500LED as stated in your sig right?

I'd love to see what's the max OC under 1.5v and what will the temp be like.
Hopefully you'll not be capped by your Zalman 9500LED at higher OC.

Looking forward to see more results
