Q6600 G0 - bad clocks off latest batches?

Lately i've been seeing a lot of people struggling to overclock their G0's - needing around 1.5v or so to break 3.2Ghz.

I'm trying to sell my Q6600, and a few doubters are saying my lapped quads that do 3.6GHz at 1.425v arent very special, while i'm arguing that the latest ones seem to be utter crap in comparison.

Anyone out there who got a Q6600 late 2007/ anytime 2008 want to share your max OC, and what voltage it needs? (esp. 3.2Ghz+ range)

Got my G0 like 1 month ago and it's doing 3.6 (400x9) at 1.47 Vcore on Abit P35-E

Please post your batch code from the CPU IHS or the label on the side of the box. Should be L7XXAXXX or L8XXBXXX or something similar.
 
So Hursah, are you running stable at 3.6 now? Don't forget to post your settings ;)
 
Yeah so far I think I got it working quite well..passed a night of Prime, and I've been doing a lot of gaming (variety, NFS: PS, Witcher, Assassin's Creed, C&C 3, etc), so far 0 issues...had to put my ram at stock DDR 800 speed for now though...dunno if I can get DDR960 speeds out of it with stability...yet...but I have my DDR800 tuned pretty well and getting pretty decent results, so I don't feel too bad about the lower DDR speed in the end.

I gotta get a pad 'n paper so I can make the "DFI Bios List" hehe! I won't forget! :toast:
 
Im wondering if this is been done on purpose by intel with the release of some 45nm cpu's alot still favoured the Q6600 because of the higher muliplyer. Perhaps they realized this and wanted to faze them out? they have recently lower the price on the quad too.

makes ya think?

True...I'm happy with my Q6600 @ 3.6 running on 1.45v load, I also have EIST/C1E on, so it idles at 2.4 with 1.37v, runs cool, load temps aren't crazy either. I gotta get my bios settings up for TSki soon though lol! Sorry man, I promise it'll happen! Just busy gathering stuff to upgrade my G/F's rig (limping hers along for now till I can replace MB/Vid/RAM/HDD/CPU).

4 cores at 3.6 is more than enough for what I'll need for quite a while...I may even go back to 3.2 just to run even cooler...we'll see what happens. I don't need any higher CPU speed then what I've got...I may see how much further I can go this weekend tho.

:toast:
 
It's cool - I'm waiting patiently ;)

As far as why new CPUs are getting worse clocks, I think it may have to do more with slowing production and better sales on higher models. When chip makers introduce new chips, the low end models are usually the only affordable ones, so sometimes they need to dip into the better chips to keep up with demand. as better chips come down in price, the slower chips don't sell as much and they need more chips for the faster models. Then, the ones that do better get marked as Q6700's and up, and the slower ones are Q6600's.
 
what seems more likely is intel has cheapened how they make them - lower sell price, but lower quality chips (less OCing)
 
I think intel is just digging deeper into the bins and selling not so great silicon anymore with the Q6XXX series.
 
This was OEM so i dont know the codes but was bought from ebuyer around march time and has a vid of *EDIT*1.2750v.

I think you mean 1.275! My chip works the same way yours does.:)

A few other settings below these left on Auto.

Read Delay Phase Adjust - 

ALL ON AUTO, both channels read 7-7-7-7-7

Messed with a little bit, but with a 333 divider it seems lowering performance 
level down to 6, which is what this allows by pulling the down per cycle (?)
 adds some instability and from what I've read is best left on auto.


With power saving features on, my CPU idles at 2.4GHz with 1.37v..sure it would be nice to have it down around 1.3v or lower, but temps are in low 30's to upper 20's at Idle so I can't complain, then under load I hit the mid to upper 50's, occasionally touching 60-62C, with 1.44v under load. My goal was 3.6GHz and I made it...dunno if I can pull off hitting DDR1000 speeds with my 4 dimms full...I may pull one 2GB kit out and see what I get, sure it'd be fine with a single 2GB kit as I verified both good at DDR1000 speeds seperately before I got the quad. But I did some tuning so DDR800 speeds nets some decent results in Everest's Cache/Memory Benchmark.

8122 Read, 7224 Write, 6980 Copy and 60.9ns Latency...sure it doesn't match my DDR1000 stuff, but before finer tuning (this was initial tuning) I was getting 7621 Read, 7225 Write, 6517 Copy and 63.8ns Latency...so while not huge, it was a decent performance benefit from going More Aggressive and Fast on some settings, and adjusting sub-timings some more. Most of the sub timing settings I adjusted are from popular recommendations for sub-timings in general on a thread I found for OC-ing my DK T2RS board...they work well, and are stable so I'm happy. I may still try for DDR960 333/800 or maybe even DDR1000 266/667 in the future again, but getting Memtest to pass either before even booting to windows has been a pain with 4x1GB...I may feed more NB voltage when I do, but for now with a small 30mm fan on my NB I'm around 39C idle and around 44C load (stress testing).

Hope this helps! :toast:
 
Cool - thanks for those. I copied them down and will look them over as soon as I get a chance. The interesting thing is that your voltage is higher than mine, but your idle and load temps are lower. Even with the best air cooling I had I was pushing 80C, but IDK what your room temps are (mine are around 72 F).
 
My room temps vary since the temps are up and down in my area...if it gets too cold, the G/F turns the damn heat on...lol! I range from around 65F to around 75F usually lol! Doesn't your X38 have 8phase?

Yeah, this board only has a 4-phase for CPU power...so that is probably donating to a higher droop requiring higher voltage.

On your Ram what's the highest stable you've achieved thus far when overclocking with a quad? I know I can get higher, but taking away about 90% of my fine tuning to do so...so not really gaining anything from it...but again that's more assumption at this point since I'm currently content and did have bad luck initially trying to OC my memory and quad at the same time doh! Lesson learned with these newer chips...it ain't my e6300 anymore!

:toast:

EDIT: Something I didn't mention under the Fine Delay settings the XXXXps values are the AUTO determined values, Current=Auto for these, I'm sure you knew that, just clarifying just in case you tried to use those values. Actually before I updated my BIOS to the 12/26 bios, they were two digit values lol! But from what I've read it's best to leave them at the Current setting, or not go +/- 30 from that value...something close to that effect.

Keep me posted on how you do! :toast:

Yeah, AFAIK it's 8-phase, and I have v-droop correction enable, which slightly overvolts. And yes, I use Corretn for mine as well.

I haven't really pushed the ram, as I had hope to just run it @ 800 and tight timings. Eventually I was hoping to go back and check for max ram FSB, max CPU fsb and the like, but too much stuff going on right now. :(
 
Yeah, well my timings/ram settings should in theory work just as well for you. You may need more or less voltage, and like I said before those sub-timings while tuned are fairly general suggestions from guide's I've read through. I was just going for stable and then started digging deeper into the memory tuning to try and extract some more performance at DDR800 speeds. I ran it like that for over 24h under Memtest, granted that was around 10-12 passes iirc, testing 4 dimms @ 4GB takes quite a while for sure...part of why I am too impatient at the moment to continue pushing further, that and I am not willing to go beyond 2.15V on my memory...while actively cooled, I don't want to push too much through em'.

With 8-phase power, you should be good to go though on the CPU, gotta say for a 4-phase MB this Dark does a good job, for me it blows my P5B Deluxe out of the water, and I believe that had 8-phase as-well. Way better bios, more stable operation from stock to OC. So I'm sure your x38 is just sweet!

:toast:
 
why not turn on the anti vdroop feature? works perfectly on my P5K-E wifi.

anti Vdroop feature? I own a P5K premium... Could you explain it? I didn't know of this feature.

Thanks!!!
 
Some boards have a feature in the BIOS that attempts to correct the vdroop when enabled. Many times this will overcompensate and result in a higher than set vcore.
 
Thanks, but what is the bios feature in the Asus P5K Mobo?
 
here's mine got about 6 months ago.

That's a nice chip with a low VID. You need to OC it some more ;)
 
won't go any higher memory tends to crap out only got ddr2 667 i need to get some 800 to unleash the power.
