Need som expertice :) Switched from E6600 to Q6600

[Audirsr]

I did switch cpu from a E6600 to a Q6600 and i had in mind to oc the Q6600 to the same spec i had my E6600 but i cant even get ner the same values.. my question is why??

Setup with my E6600:
Motherboard Abit AWD9 MAX
Cpu E6600 2,4ghz with zalman CNPS 9700
Ram Corsair Dominator pc 6400 cl4 running 4 4 4 12 at 2,1v
Saphire 1950XT 512mb
Coolmaster 650W

389x9=3501
PSB 1333
1:1 667
389 (778)
Core 1,4125
This setup working fina and rock stable.

So the only thing i did change was to the Q6600 cpu and did try som oc but that suck big time i cant even get it stable at 300x9=2700mhz it dosent matter if i rase the vcore from stock and all the way up to 1,56 i dosent help att all.

So what could be the problem with the new Q6600 its a G0?
For now i have switched back to my old E6600 and running the spec as above. Maby i will give it one more try later with the Q6600 but if i cant even get it stable at 2700mhz isint it better to go with E6600 anf 3501mhz insted??

My guess is there's a setting or two in the bios that's not quite right. I'd start by clearing the bios and letting the Q6600 redetect.

Leave the memory at 1:1 to start, make sure the memory voltage is corect, and don't change anything on the cpu but the fsb. You should not have to raise vcore at 300 or 333.

How are your temps?

 

[Saiyukimot]

Your Vcore is far too high! That maybe the reason - more voltage increases the temperature...


My Q6600 is stable at 3GHz at 1.2v! lol, try stock voltage being 1.232 for mine at least.
Also drop your RAM from 4-4-4-12 to 5-5-5-15 to make sure your RAM isn't the problem. Also, my RAMs at 5-5-5-15 at 1.8v, maybe yours being at 2.1 is affecting it? Remember, Intel processors arn't as 'sensitive' to memory timings like AMD are, so 4-4-4-12 to 5-5-5-15 is going to make almost no difference in performance at all.

Remember though that a Q6600 is just 2 E6600's slapped together so its harder to overclock them Is yours G0 or B3 also?

I did clear bios and started fresh. Memory is not the problem becasu it works fine with the E6600 cpu. I cant go more them 300fsb then it starts to thorw me out of XP and starts over.
Temps are good np there... idle 26 and hmm think load was somthing between 40-50.

The tempature is low 26 idle and somthing over 40 load but vcore says 1,28 somthing as standard in bios. I can try to lower the Vcore... for higher dosent help anyway. The ram isent the problem there are either 5 5 5 15 at 1,8v or 4 4 4 12 at 2,1v have tried but that dosent mather. Its a G0 cpu.

But it kinda suck if i dont get over 2700mhz... is it better do go for the dual at 3501mhz ot the quad around 2700mhz?

Something isn't quite right. I've never heard of a Q6600 GO that wouldn't overclock at all.

You might try http://forum.abit-usa.com/forumdisplay.php?f=48 where there are some folks with more experience using your motherboard.

Thank you for that link... there is some trouble with the motherboard for Q6600 G0 stepping so there is a new bios on its way

uhhh...

1. Dual core and Quad cores are different. I dont care who told you there simular, there not. Most of the communications is done VIA FSB. Remember both cores need to communicate to one another.

2. Try uping your NB voltages. Im guessing your NB needs a little tweek in its votlage.

3. 1.35Vcore should be ABSOLUTE MAX for your HSF, unless you want to fry some bacon and eggs for breakfast during a long encode/game session. 3.2ghz would be about near upper oc point without replacing that sink.

4. Want to overclock near spec to your E6600, Get a new sink Ultra120 or Tuniq Tower. Zalman sucks crap on quadcores period.


And who am i telling you all this. I have 5 quadcores, on asus, gigabyte, and abit platforms.

okey after looking at your sig, please explain to me how the hell your pulling off 66c under max torcher. What temp program are you using. 1.47Vcore is water territory my friend. Even for G0

The Average G0 should do 3.6ghz @ ~1.42Vcore +/- .01-.02

Water? Never touch the stuff. I do have a Sonata with twin 120s in and out.

My temps are CoreTemp, confirmed by adding +15 to Speedfan. 1.47v is what it takes to run perfectly stable at 3.6 on my GO stepping Q6600 with vid of 1.31. I could get 3.0g at the stock voltage, 3.2g at 1.35, 3.4 at 1.37.

I can boot into Windows at 3.6g and run most apps fine at 1.42 or so in the bios, but after vdroop that's only 1.36 as measured by Speedfan under full load. It would give me errors in Prime95. To get over the hump, 1.47 works, and the cpu never sees that much voltage. With Speedstep enabled it idles at 2.4g, 1.3v (same as VID,) and fully loaded at 3.6 the measured vcore is 1.42 or thereabouts.

Now that ambient temps are feeling like fall, my system idles under 40C and Primes at about 60c. If I max all the cores I can hit mid-60s.

Hope that's explanation enough for you, my friend.

mmmmm..... sort of.

So your 1.47 is bios lvls? And vdroop would put you around 1.42-1.43

I thought you were quotting actualy vcore readings. You should try out the newest version of CPU-Z. It tells accurately the actual Vcore reading.


whats really suprising me is on how that roswell is keeping up with a tuniq tower and ultra120. Thats why im curious. If that sink is that great, i may give it a try on an air build.

 

[wittangamo]

Thanks for the tip on CPU-Z. The version I was using only had VID and not Vcore.

I've been getting the Vcore from Speedfan, which reads about the same. Sorry if I confused the issue by quoting the bios setting in my sig.

There aren't many reviews on the Rosewill cooler. I did see one where it hung within 3 degrees of an Ultra120, and I picked it up for under $30 bundled with the cpu at the egg. It does pretty well for a mid-sized cooler with a 92mm fan. Idles quiet at 1500 rpm, not too loud at full 2400 rpm.
