Should I downgrade my CPU?

I am having problems with mixed CPU temprature readings which are stopping me from achieving a reasonable overclock with my QX6700 and Striker Extreme. I have raised the issue on several forums but no-one seems able to help me.

I have come to the conclusion that it would be better to sell my QX6700 B3 and buy a Q6600 GO. With the £100 profit I could invest in a Thermalright Ultra 120 Extreme CPU cooler and Thermalright 8800 GPU cooler.

I would probably be able to acheive a higher clock speed with this.

Do others agree with this or am I raving mad?!:eek:
 
Sorry I did not provide much info this time round...

The problem is that CoreTemp is showing my tempratures HIGH even at stock when the cpu is under stress (SP2004 etc). Everything else reports differently (speedfan etc) but I am re-assured that CoreTemp IS correct....

Even after calibrating my results are:

Idle 1.6GHz/Vcore 1.25v - Ambient 26c, Tcase 27c & Core0 36c

Idle 2.6GHz (stock) Vcore Auto - Speedfan = Tcase 31c, Core0 41c
Idle 2.6GHz (stock) Vcore Auto - CoreTemp = Core0 48c

(CPU100%) 2.6GHz (stock) Vcore Auto - Speedfan = Tcase 63c, Core0 65c
(CPU100%) 2.6GHz (stock) Vcore Auto - CoreTemp = Core0 77c

With regards to price I have had a look on eBay and QX6700 are selling 2nd hand for £230 and QX6600 are selling for £130 so as long as I bide my tiem I should get £100 profit.

What you gusy think?
 
Yeah I have re-seated the CPU and the BigTyp several times.

I am using the thermal gresse provided with the Big Typ. I appreciate I could get some Shin Etsu x23 or something similar and that would give me a few extra degrees but I surely shouldnt be getting these temps with my setup (Antec 900 case etc).

I am applying the grease in a penny sized circle in the centre of the CPU. Not too much etc
 
Hmmm never done that before but I guess there is a 1st time for everything :-)

Im just convinced I have got a duff CPU as other people can get more from there Q6600 with the same setup than I can with my QX6700. If you guys think it woudl be better to stick with the QX6700 then I would take advice (Im new to all this OC lark).

Would I not be better to get a low VID Go Stepping Q6600 and lap that!?!?

Also do either of you guys understand why CoreTemp has different core temp readings than SpeedFan (even after I have re-calibrated)?
 
OK so your advice is dont give up on my cpu.

Love it, lap it and buy it some Shin Etsu x23 for valentines.

I assume you are basing that advice on the fact that the QX6700 SHOULD be a much better CPU than the Q6600 so its worth a triwl??
 
Re-seated my CPU and HS again, applied the TIM like you said and my idle core temps have gone up by 7c in CoreTemp and 10c in SpeedFan :-(

The BigTyp is a bitch to fit with the striker becasue of the pipes around the CPU.

Oh well I give up for now
 
To be honest I have lost confidence in both the CPU and HS.

The bottom of the BigTyp seems to have small indents in it which you can feel when you run your finger over it. I put both the CPU and HS on a sheet of glass and everything looks ok, no obvious concaves.

Perhaps a good HS lapping is in order but I think I would prefer to sell my parts if I can and get a GO stepping Q6600 with a low VID and a TR Ultra 120V Extreme and start again.

The BT nearly ended up in pieces when I was trying to fit it anyhow!!

Better switch off now before my PC melts.

Thanks again for your help and advice... I will be back!
 
Put my QX6700 on e-bay and sold straight away for £240 :-)

Now need to buy a GO Stepping Q6600 lapped with low VID for £140 and a TR Ultra 120 Extreme HS.
