E6600 retail on P5W DH 3.6G stable

[Kantana]

Want to compile a list of settings and temps for the conroes on P5W DH, settings used etc. Here's mine, dual prime stable 12+ hrs:

Intel E6600 retail steping 6 B2
Corsair Cool water cooling
P5W DH bios 0903

FSB 400
Memory 800
Timing 5-5-5-12-5
Vmem 1.9 v
Vcore 1.5375 v
Vmch 1.6 v
Vich Auto
Vfsb Auto

Temp ambient 26 degrees c
Temp idle 41 degrees c
Temp load 60 degrees c

Note the above temps are reported by the motherboard sensors in speedfan, the actual temps of the cores are 74 degrees c under load (out of max of 85 degrees c before thermal throttling occurs)

Want to be able to graph the max Vcore/temp for stable overclocks so we can get some kind of range for each conroe model.

Try raising the Vmch to 1.65 and crank it up more.. Are you able to boot with tighter timings, such as 4,4,4,12?

[Brahmzy]

Nice OC for a retail E6600...don't think anybody with a 965P has done that yet...

[Kantana]

The highest I could boot at was 445 FSB for 4G total speed that was at:

Vcore 1.6 v
Vmch 1.65 v

It could boot into windows but was totally unstable. Couldn't get Dual Prime to run it would error almost immediately however SuperPi 1M could complete in 13.3 s

I also had a E6400 that was dual prime stable at 438 FSB for 3.5G total speed at:

Vcore 1.525 v
Vmch 1.65 v

However the SuperPi 1M score was 16.5 s which is much worse than that of my E6600 at 3.6G

I am watercooling so I believe I have hit the limit on my E6600 for 24/7 stability. I read that the max Vcore that could be applied to the Conroes are 1.55v so without pushing that any higher and judging by my temps I don't believe I could push the FSB any higher and still have stability.
Looking at all the other posts including those from X6800 owners on water cooling I believe the max overclock speeds for stabel 24/7 operation is between 3.4G to 4G depending on the motherboard and exact chip used. For sure the stepping 6 appear to be worse overclockers than the ES chips.

3.6GHz is pretty much what peopel expect E6600 retail to reach AT LEAST...

can u go higher?? i dunno.. vmods??

yet another person thinks that retails chips r crap compare to ES5 ... thats what i have been saying for the past couple months , actually about 1.5 month

look at my sig for reason

[AndrewZorn]

what woudl you suppose is the max fsb for your board

[Kantana]

Dunno the answer to that one, I have had the E6400 on 450 FSB for total speed of 3.6G but not tested stability as it was running at 1.6 Vcore and I didn't want to blow that chip. This was using Vmch of 1.65v
I believe the max FSB also depends on the multiplier used so a E6300 would be able to run at higher FSB than a E6700.
BTW I removed the metal covering on the NB heat sink and added a small fan so that it is kept cooler. At higher FSB this gets very hot.

nice work,subscribed;)

Note the above temps are reported by the motherboard sensors in speedfan, the actual temps of the cores are 74 degrees c under load (out of max of 85 degrees c before thermal throttling occurs)
:eek: Your saying it is hitting 74C under load with WC? That doesn't seem right and/or safe :confused:

[AndrewZorn]

yes sounds too hot for 65nm

[M.Beier]

Cool :)

Running 400*9 as well

1.6125V though

Ok just to clear this up, I believe everyone is posting temps as reported by speedfan or ASUS AI etc this uses the analogue sensor on the motherboard which reports 61 degrees c on my board.
I use a second app that measures the temp as reported by each core via a digital sensor that is built into each chip. Each cores gets to 74 degrees c which is equivalent to 61 degrees c as measured by the analogue sensor. For ref the max Tcase for each core is 85 degrees c so if I only get to 74 degrees c that means I have 11 degrees c to go before thermal throttling even kicks in.
My temps if I use the same sensor as reported elsewhere on this forum is 61 degrees c.

You have very high 3DMark05 scores there, is this in a crossfire setup or single card? My X1900XTX single card at 780/834 clocks only score 13,800+ using the E6600 at 3.6G.

[Haltech]

Theres no way that chip is getting that hot. I dont believe any of the sensors on the Asus board whatsoever.

The temp reported by the analogue sensor on chip/motherboard is 61 degrees c but the conroe also has 2 extra digital sensors on the cpu and they report 74 degrees c under full load.

There is a 15 degrees c delta between the analogue/digital sensors. Looks normal to me as the core duo in my notebook has the same different readings.

Was with T2600 @ 3400mhz
x1900XTX at 800/900
- 15193

14963 with 3200mhz but 800/1021

[Shrekogre]

can u share your batch number? it should be on the box. thanks

You mean you were overclocking the Core Duo mobile cpu? How did you get the mem clocks on X1900XTX so high? I thought those chips are 1.1ns so highest rated would be 900?

[Haltech]

I still dont believe that chip is getting that hot. Thats GPU hot territory.

sure seems that way, my x1900 gets about that hot
but who knows maybe its bad contact on block and cpu

Well it just clocked great :D

Used -25 deg liquid, sadly I couldnt get my core too hit 900mhz :(

Atm Im using a x850XT at 688/600 tweaked vids, thats more like 9K :(

lol i'm running a not retail but a tray E6600 on a stock not modded P5W DH Deluxe with 0903 bios, with no water cooling but just Freezer 7 Pro @ ultra LOW fan speed, and i'm running it @ 400x9 = 3600 MHZ

And also the rams are running @ 400x2 = 800 Mhz but with these timings: 3-3-3-4

Stable @ 3DMark2006 with 10 Loops for each test, global score 10.000, CPU Score 3177

I think you can do way better with the water cooling, this is not an extraordinary result i think, but anyone can do it with a standard not modded stock cooling not high voltages system, show us some impressive frequenzies with the water cooling pls :D

Neither did he claim so, its just to give people a picture :)

What Vcore are you running that at? Temps reported by MB and cores? OPls post the week numbers for your cpu.

[OBR]

My E6600 is pretty stable at 3.6 too, my best oc with all benchmarks stable is 3.8Ghz (420x9)

[lawrywild]

Glad to see someone else using coretemp

with 1.55v probeII shows about 58-60 degrees for me but coretemp is around 71-72..

I don't know what to believe..

maybe bad internal IHS contact
