E6750 Retail - Some results Air Cooled

[DerekT]

Guys. Have you tested if the cpu:dram multipliers works? I mean : can you use something else than 1:1 on 965p motherboards?
I'm asking this becouse somenone tested an e6750 on a dfi dark and other ratio than 1:1 doesn't works.

On this P5K.

Multiplier = 8 X
Strap = 200Mhz
FSB = 450Mhz
Mem Freq. Avail = 1500Mhz, or 1800Mhz

Multiplier = 8 X
Strap = 266MHz
FSB = 450MHz
Mem Freq. Avail = 1125Mhz, 1350Mhz, 1800Mhz

Multiplier = 8 X
Strap = 333Mhz
FSB = 450Mhz
Mem Freq. Avail = 900Mhz, 1080Mhz, 1440Mhz

mikal, whereabouts in ma are you from? I have the same batch (l719a747) e6750 as you, and am getting horrid results. got an ip35-e enroute in case that helps over my dfi p965-s which runs 24/7 at 8x450=3600 with my e6400.

That's where I stand with my setup, and yes, it desires 1.5V as less does not give me long term stability, and I want long term proof for purposes of folding.



You can download Everest which will give you a more true voltage reading or you can use ASUS Probe II which will as well. With regard to the CPU idle thermals, it would seem that a new offset needs to be created for this new revision. I had personally thought that with the release of the Intel digital thermal sensors embedded singularly in the core, this would be a thing of the past. It's rather confusing as to why the DTS does not give a true reading. It's also quite nonsensical that the CPU reading would be of a higher thermal than the core readings. This is contrary to simple electronic physics.

Have you downloaded the latest BIOS (P5B Deluxe BIOS version 1215)?

EDIT:


I never use stock cooling, and I would think that you might well find thermal and other issues with stock cooling. Also, even though P5B has allowed a 1333FSB processor, there might well be upcoming BIOS fixes that correct and offset the temperatures to bring them more in line at the low level and possibly at the top level as well.

I advise you to move to better cooling. 3.6Ghz and 1.5V is not a good spot for the Intel Stock Heatsink.

Yeah I'm using the latest BIOS, will have to get some aftermarket cooling it seems.

I got my E6750 this morning. First boot into Windows was at 3.2Ghz and stock volts.

Seems stable at 3640mhz. 5FSB more and orthos fails.





I imagine this chip would do a lot more given better cooling.

I was asking for rezults on 965p chipset not p35 .

I also have an E6750, fpo: L722A247.
Currently I have stock cooling. Now doing Orthos Ram stressing at 3.3Ghz. Voltage is the basic setting. Tat says it's at 51 degrees after 10 minutes Orthos. Ohh it stopped just now. My Kingmax 1066 seems to be very bad, now they are at 2.1V and fails in Orthos after 4 minutes@1000Mhz. :S
What is the max. voltage i should give to the ram?
Having P5KC mobo.

[Drizzthsz]

Though 3.2 is stable for sure.

I'm currently testing 3360MHz - 420FSB x8 4:5 using the following settings that has been stable for over an hour:

CPU Voltage: 1.4
CPU Voltage Reference: AUTO
CPU Voltage Damper: Enabled
CPU PLL Voltage: 1.50
DRAM Voltage: 2.20
FSB Termination Voltage: 1.40
North Bridge Voltage: 1.40
North Bridge Voltage Reference: AUTO
South Bridge Voltage: 1.20

Personally I leave my memory voltage at stock and adjust the FSB Termination Voltage, North Bridge Voltage and the South Bridge Voltage to find the max stable memory frequency. I did this with a low (333+) FSB and used the dividers to raise the memory frequency until I found the max stable.

I quess you tested on the p5k. Can anybody test a 965p mobo ? (cpu:dram ratio)

[DerekT]

My mistake. On Intel chipsets, you can only run a divider upwards. In other words, you are only allowed to run your RAM faster than the CPU. All the dividers on P965/P35 (4:5, 2:3, 3:4, 1:2, 5:6, 5:8, etc) are dividers that run the memory faster than at 1:1 FSB : DRAM. The nVidia chipsets can clock memory independently to the FSB.

I knew that. The problem is that somenone tested a DFI Dark + e6750 and all the dividers but 1:1 don't work. Even if you select other divider the ratio still remains 1:1. That's a big problem for me because i'm going to have 2GB Mushkin D9 that can reach 1200+ 5-5-5-x, and if i can't use other divider than 1:1 i'll actually be limited at 500+ mhz for memory.

Please someone else test this.

I have the 965P chipset Gigabyte 965p-ds3p rev 3.3, just as i was curious i tested it out on another ratio have a look at image ... maybe its just the dfi bios bug???



but i like the 1:1 on my mem as its pretty cheap

[jhl81]

hmm image not showing ... ok I'll link it ...

weee got my playtoys today.. will post some tests later , played a bit CSS and it seems stable so far

1,6vcore on board and 1,56 real. everything aircooled.

You might want to try CPU-Z 1.40.8 and see if it shows your 1.56 real core voltage.

hey guys, I'm new around here, just got my e6750 up and running. its rock solid @ 3.2Ghz with the shipped BIOS, I flashed to 1303 hopping to get 3.6 out of it. havn't really had time to push it yet, but so far I'm enjoying my new machine. sure beats the hell out of my old 2800xp/5900xt machine

[MacClipper]

Chucked aside the Q6600 and back to E6750 fun for now, duals are so much easier to clock.

3.72GHz at 465x8 1.45V BIOS on shaded Commando,

[RPGWiZaRD]

zaer0> Nice! I got a confirmation yesterday from DriveCity.de that my order with my E6750 tray has been shipped, I think these are probably really fresh ones as it seems they ran out of stock just before I ordered and I ordered on Friday last week and there's more in stock of them now so this might be interesting if got a fresh new batch. Where you got yours from btw?

Hope mine will overclock as good. xD Will of course post results later. Hmm, very various results from this chip, 4GHz 1.56v and 3.4~3.5GHz 1.5~1.55v. Hard to say what to expect before you get to test them out yourself.

[sam95ta]

Can some one help me with my 6750.I can easly do 3.75 orthos stable,low volts 1.46 and good temps 49 load.Anything above 3.75 no mater how many volts I give it windows will not load.Is it my p5b deluxe or this cpu.Thinking I may need a p35 board to go higher.

I heard that you could go a little higher with p35 chipsets but how high do you want to go?? for the extra 100 or 200mhz idon't think its worth it imo. i have the 965P chipset and i'm running 3.9 and i've seen alot of ppl stuck at around 3.6 even with the p35 chipset boards so i think its more your processor not your motherboard thats the hold back.

A friend have buy one of theese processors. Testing it here is the result:

nice overclock, mines wont go over 3.8 without crazy volts & temps, settle for 3.7

Hi, no problems using 1:1 on P5B Deluxe and L719B030 E6750. 515x8

[alex17 GTX]

Pff. Can't you read all? I said the other dividers don't work. 1:1 is the only one that works on DFI Dark
