E6600, can't get stable at 3.6ghz (400x9) FPO#L632B086

[r00t3d]

Interesting read on this thread.
smsmasters- I used to use the Freezer 7 Pro but this morning my Scythe Infinity and Antec 900 case arrived and damn the difference is huge.

I can now do 400x9 w 1.35v Orthos Stable and CPU load temp @ 55c
This would have been almost impossible with the Freezer 7 Pro.


I am going to leave Orthos running overnight see how stable this really is.
Just to confirm the voltage is 1.335 in Bios and 1.35-1.36 in Windows.

[smsmasters]

I noticed that your e6600 has a VID of 1.2375V, mine is 1.325V.

What voltage did you need and what and temps did you get with ur AC7Pro?

Here are my final overclock results I need more powerful case fans.

Can you 32M SuperPI?

[smsmasters]

I haven't tried 32M superpi yet. I will try it later.

Ok, here is a superpi 32m screenshot I just did (at the same time I was doing web browsing so it may have slowed down the results)

I need 1.58 actual vcore to be stable at 3.6GHz.

[lad]

I hope this isn't considered thread-jacking
but I've been looking for systems ~3.5 GHz running less
than 1.4 vcore, to compare my setup to.

I'm running a 6600 at 3.55 GHz, 1.38 vcore with a TT BT VX
with several mods on it, and I'm getting temps like r00t3d
is getting. Yet I see other threads with the Infinity,
and low 50's temps at 1.5 vcore!? This lead me to think
my BT wasn't cooling effectively. I've been considering
getting the Infinity, but really don't want to spend the
time to yank the mobo out of the case and get hardware
for a high-pressure mount mod on it. At the same time,
I'd like to OC higher without higher temps. I'm guessing
I'd have to go 410 FSB to make up for the loss in memory
timing with the jump to longer NB latency from my current
394 FSB - there's no way I'd get acceptable small-fft temps
there...

[Halvie]

lad those temps seem way high for using a TT BT and only having 1.38 actual vcore. I have the regular BT and have 1.45 actual vcore and have a temp of 48c-50c(from coretemp) with load from orthos.

[r00t3d]

I used the supplied thermal paste for some reason, probably in the rush to get it all setup. Not sure if it would make a difference if I had used AS5 but I am going to run my rig 24/7 380FSB using the current setup with idle 29c and load 44c.

Currently workin on tighter RAM timings 380MHz 443-5 at the moment.

So in the end did you put a fan over the NB?

Also at 75C that is WAY too hot. Both mine and my buddy's E6600 at 3.6ghz only run at 58C Load.

Also your vcore is way high. My vcore is at 1.38 for 3.6ghz and my buddy's is at 1.43. The reason why u need so much vcore is probably cuz ur proc is just too hot to begin with. My buddy's stepping is the same as yours so you should need pretty much the same vcore to reach the same speeds.

I didn't put any fans on the NB. I did the pencil mod and I can now set 1.45V in the BIOS and 1.43V actual steady at idle/load.

This e6600 I'm "borrowing" is doing 3.6GHz with these settings,

BIOS 0910

400 x 9

CPU - 1.375v in BIOS, which is 1.38v in Windows(with BIOS 1004 it required 1.3875v, which was 1.39v in Windows) after pencil modding. Before it had to be set to 1.46v in BIOS, which was 1.42v idle and 1.39v under load

VDimm - 1.90v 20-8-4-4-4 G.Skill HZ's

FSB - 1.20v

NB - 1.45v

SB - 1.50v

ICH - 1.057v

Hi, what is the full batch number of your cpu?

[Calcu]

I didn't look at it before I put it in but I'll let you know once I pull it out,

[adamsleath]

since i changed from 0701 then 1002 to 0402 bios i have been able to get 3.6 stable at a lot less voltage (1.42vcore/1.4)

with 0701and1002 i needed1.5v+ to achieve 3.6 stable

unfortunately 0402 has a lot of droop so i have to set 1.525 in order to get 1.42v real !!


...my point being that using diff bios helped me...
dont know whether the same may be true of p5bd?

[safan80]

I didn't look at it before I put it in but I'll let you know once I pull it out,

it's also on the box it came in if you still have that.

[smsmasters]

Finally got a new Antec 900 case. My cpu load temps are now 55C in orthos What a difference a new case makes! Before I had a Thermaltake Soprano and it was like an oven inside. Also changed my PSU to the Corsair HX520 and the voltages are rock solid.

[jacky89]

Which bios version are you using? I used to be able to o/c to 8x467=3736mhz with my E6600 when using Bios version 0507. However, I upgraded to 0704 and it is having difficulties at 3600mhz. I dont know what the heck is going on. Asus won't let me downgrade back to any bios earlier than 0603. I tried all three methods, ez flash in bios, boot disk with afudos, and the asus update windows program all say any bios earlier than 0603 is too old and can not be flashed.

0603 sucks just like 0704.

[smsmasters]

I'm using 1216

[Nazu]

My E6600 did 3.7GHz on air. Vcore was pretty high (1.58v set in bios) but it ran Orthos 14h and was stable in games.
