E6750 Results

Just got one of these 8x chuggers.

Test bits:

Asus P5N32-E SLI
http://www.wprime.net/6750/motherboard.jpg

2x512MB Mushkin XP2-6400
http://www.wprime.net/6750/memory.jpg

Core 2 Duo E6750
http://www.wprime.net/6750/cpu.jpg

Setup

First screeny at stock:

and a pi run

Quick bump to 375FSB = 3GHz; still at stock vcore.

Bump to 400FSB = 3.2GHz; still at stock vcore.

425 = No boot

Upped the chipset and vtt voltage and she's back in business.

I wanna see the overclockability of Intel's new line-up! Keep up good works.

3.5GHz stock vcore (I'll find one what stock is in a moment)

Ok it's not so 'stock vcore' - board seems to be setting 1.5V regardless of what vcore I set (or auto). Booting at 3.6 atm.

3.6GHz; 1.5V; PI 1M (dual 4M stable)

Just noticed Core Temp is telling me Rev E0 (CPUz says nothing).

3.7GHz - Stupid Bios sets 1.5V no matter what vcore I set...:S

Booting at 3.8GHz - reboot on its way to windows.

what?! i can see the factory writing!

most likely, it's as concave as a radar dish; lap that thing immediately!!

(voiding your warranty *can* be fun and worthwhile, afterall!)

:)

nice results thus far, keep posting!

very nice, and I had that voltage problem with my DS3 for a while, it corrected itself when I swapped out CPUs (E6600 to D805 and back again).

Like I get any warranties on these things :P

Just flashing bios to original so I get vcore setting. I hope it supports E6750.

3.8GHz 1.58V (actual)

501 bios

1.38.2 CPUz

Damn no post on 500FSB.

And I lost my windows installation at 487.5

Does anyone predict a greater frequency ceiling with these 1333 FSB chips? Because to me this seems like a E6420 (8x multi with 4 mb L2 cache) that is already factory overclocked to 333 FSB (rather than 266 FSB).

Why would I want one of these vs a e6420 if I am an overclocker? (unless 1333 FSB chips clock better overall?)

Overclocking != warranty :nono:

Yeah I was just telling a friend E6420==E6750. Just cover up one of the BSEL contacts and your 6420 is a 6750...

Well, I am a poor man... waiting to buy a E4400, which is a E6700 with 2MB cache covered up... and of course, they also screwed the VT thingy as a bonus, which I don't give a dingo's ass about it :D

One thing I noticed about the E6750, compared with an E6700 B1, it runs a good 15C lower both @ 3.8GHz (1.6V).

Wow! That is interesting. But are you sure it was the chip and not other variables?

Same hsf, but upon inspection the B1's spreader is curved inwards...:S But the E0 sits in the bios at a good 22C at 3.8GHz 1.6V thanks to Asus' patent-pending "Let's minus 20 degrees off whatever temperature we read" thermal reduction system allowing up to 20 degrees cooler temperatures than the nearest competitor. (that's around 54C in Core Temp).

These chips are aimed at joe public I believe, they can plug them into one of Intels new chipsets which run a 1333MHz-System Bus, slightly better stock performance than a machine running at 1066Mhz system Bus.

Thats interesting, I wonder could u 'reverse' the process?

Are u sure about that? I am reading the the E4400 is a fresh chip based on the Allendale core (same as E4300) these things are meant to be manufactured with just 2MB, nothing disabled?

Thats good to know, my e6300 B2 seems to be a very hot chip indeed, just waiting for a new Heatsink to arrrive to find out whether its the chip or the kak Arctic Freezer 7 Pro?

I'm not sure if this tread is still active by now, but just wanted to update to say I have had good daily 4GHz on air with my E6750 @ 1.567v/1.642v PLL/63x GTL Ref and OCCT load temp to 60~65c and 33c idle with configuration in my sig as of 12-05-07

I think that's a bit too much vcore for 24/7.
You can lower it to 3.6GHz or 3.7GHz and you won't actually feel any difference but vcore will be much lower.

wwwww it seems like your chips is as bad as one e6750 that i used have.. the fsb wall was at 475.. :shakes:
