P5B Wifi + e6600 overclock

Slinwagh · 20 May 2007 at 23:24

I am struggling to push my 6600 over 3GHz.

I have tried various setting but basically 375 x 8 is the highest stable setting I have reached.

With almost every other multiplier/FSB combination the overclock is unstable.

My BIOS setting are as follows.

Try increasing the PCI-E bus to 105. Also try upping the VCore on the CPU. There is a good chance that the board isn't actually supplying 1.4v [use CPU-z to find out].

I haven't upped the vCore becasue I was hitting 62'c underload.

CPU-Z reports vCore @ 1.35 / 1.36

62C? What cooler do you have?

Slinwagh · 21 May 2007 at 01:21

Scythe Ninja in a Temjin TJ06

Currenly idle @ 46'c using Speedfan

try re setting the heatsink

Is a real blag in my case as the motherboard is mounted upside down so I can't get my hand in to release the clips. To do it the motherboard has to come out!

Saying that,it has been reseated and it appeared that there was good contact as the "grain" of Arctic Silver compound had been spread evenly when i took it of.

I think I'm going to order the Antec P182 anyhow.

What does TAT say?

I don't know sorry it wont run. It flashes up and then closes almost instantly.

46C is pretty warm for idle given your OC.

My E6600 @ 3.3 is on a Scythe Ninja and my idle is usually around 35C. Load is around 57/58C.

If you are sure the Ninja is seated properly I would look at airflow in and out of your case. Does the exhaust air from the Ninja get out of the case quickly? [ie is pointing at an outtake fan].

Slinwagh · 21 May 2007 at 02:34

From the front to the Scythe I have a 120mm fan drawing air in, the Scythe fan is blowing through the heatsink out through the back with another fan drawing air out.

SiriusB · 21 May 2007 at 02:40

Is there any intake fans?

Usually a nearby outtake fan is enough but I am trying to find out why your chip is so toasty compared to mine.

As a point of interest, what is your idle temp at stock speed with stock volts? I remember my E6600 was at around 30C at stock idle.

Idle at stock speed was definitely low to mid 30's no more.

Case temp is reported as 35'c according to Speedfan.

Not sure what is going on then. All I can suggest is a reseat

Pain in the arse I know but if it fixes your temps then its all good.

I am going to get the Antec P182 so I can do it then!

Slinwagh · 22 May 2007 at 17:12

I have just put everything into the P182 with a Noctua Noctua NH-U12F and I am still getting load temps of 60'c

The fan is blowing through the fins of the heatsink to the roof of the case and then a fan is sucking air out through the vent.

Slinwagh · 22 May 2007 at 22:37

Right this is beginning to cheese me off now.

I have put everything back to stock, re seated the cooler, cleaned and reapplied Arctic Silver 5 and under load I am getting temps of.......

48 -49'c !!!

Idle temps are 37 - 39'c.

I am 100% sure looking at the CPU and cooler that the contact is good, the covering of Arctic Silver is even.

So thats about 1.4vCore in BIOS then? Hmm I would expect your chip to go a little higher on that voltage?

If TAT wont run on your ASUS P5b-Deluxe (Board I am also using) then there is a problem? dunno what that problem is but it may also be holding back your overclock.

Make TAT work.

I understand that you are miffed but get your trouble-shooting head on and try and fix it, you will be well chuffed when you solve the mystery of the 'Slinwagh Conroe'

I am also getting higher temps than I would like but it doesn't appear to be affecting anything, I don't think its holding back my overclock because if I add more vCore the computer runs stably. If it was a heat issue then Orthos would error even faster when you add more vCore but in my scenario it doesn't?

Get TAT working and then whack up the vCore (for testing purposes).

Slinwagh · 23 May 2007 at 02:17

TAT doesn't load due to the tat.sys file being a 32bit driver according to the logs.

ALL supplied motherboard software is terrible, on top of that, 95% of onboard motherboard temp sensors arent accurate, or the temp reading is offset dramatically by software or the bios.

Dont treat the temperature as a given, install other coolers (ie stock cooler) and see if the Ninja / Noctua is better (should be a lot better). If not, its in your mounting.

The temp reading is almost never correct, but as it is a constant, improving or worsening the cooling should yield the correct difference.
