Thanks for the feedback all. Pretty satisfied with the core I have now.
I have Vid of 1.325 :(.
Which setup should get me better performance?
I can do 8X425 at 1.425 OR 9 X 400 @ 1.525. My DDR2-800 memory on the 8X425 is a nice o/c at 4-4-412 2T on 2B strap. The system actually feels faster on the 8X425.
I guess my first comment is that the temps you are getting is inline with what I used to see myself with air cooling. furthermore, that 4-6 C diffrence in core temps is normal. my old B3 stepping Q6600 got within 2 C of each other after lapping, but doing the same with my new G) stepping did nothing. Intel seems to have a bit of an issue with IHS contact with their CPU cores. Having said that, I have a few ideas for you to try.Quote:

Next, I would focus tuning your GTL levels. Doing so allowed me to lower volts down to 1.275 vCore in BIOS for 3600 MHz, and also lowered my temperatures by about 4 C. Your results may vary, but the right GTL settings make the whole system more efficient.
Third, if you haven't done so, try remounting HSF with a better grade thermal paste (I have used Arctic Silver 5, but am currently using arctic Cooling MX-2). Follow the directions for putting thermal paste on Intel quad core CPU's as outlined on Arctic Silvers website.
i got this pm from a guy who doesnt accept pm's so if you are reading this dude, here you go

So these chips have been out for a while now and I'm wondering how they are holding up for people with 24/7 overclocks? I have mine stable with reasonable voltages and temps and my cooling can handle more but I'm only interested in 24/7 settings. Are people seeing any degradation of their performance (needing more voltage than before, lower FSB than before, etc.) with speeds like 3.8 Ghz and higher? I'm assuming I can get to 3.8 with just over 1.4v and keep the load temps still in the mid 50's but I'm not going to do this if it's going to make my system perform worse somewhere down the road.

If you are going to o/c not higher than 3.6ghz, keep the one with lower load temp.
By the way, where did you get them from? There was one L744A469 at Tustin Microcenter last week. I picked up an L745A793 as a back up CPU instead of the other, and it looks like I made a good judgement.:clap:
You know that there's very little benefit running the memory and FSB async, except on memory benchmarks. It will only stress your memoies and NB, which means more heat.Quote:

Right now all other voltages are at default, but I would like to get it to 475x8 if possible. I think I am FSB limited right now as I can't get 475 to work at lower multipliers either. Any suggestions on what to tweak to try and get 25 more on the fsb?
Long story short, my dad got himself a new pc and didn't mind swapping the q6600 i "accidentally found" in it for my pos e4300 (3.2g @ 1.5v).

only had it for about a hour and it's looking good :yepp: more tests will follow
try adding 0.1v to vnb.. if that fails 9.0 multi is an optionQuote:

I'm going to stick with my original L739A466 with the lower volts. It turns out that the L744A469 needed 0.01V more to be truly stable, and by then the temperatures were about equal. The L744 had a 5C difference between the core pairs while the L739 had only a 2-3C difference. I attribute some of that to the shape of the IHS mating to my lapped Ultima-90 heatsink.
What's interesting is that I see some people with low VID Q6600's, low vcores at 3.6 GHz, and a TRUE 120 getting similar temperatures to my overclock and setup.
Hello there. I'm here because I need huge support on this.
Here is the information about my Q6600 G0 stepping:
BX80562Q6600SLACR - L737A716 - Packed 10/18/07
This is my VID, and also my idle temperatures using a Thermalright Ultima-90i + Zalman ZM-F3 120mmx25mm fan on the system stated in my signature:
http://www.uploadfilesystem.com/en//...2/Sxh33233.png
The thing is, I haven't been able to overclock it. Wherever I just up it 60 MHz, it will just restart unexpected. I even overclocked it to 3.6 GHz once, and even passed eight Prime95 hours, and just when I opened Mozilla Firefox to post it on some forums, including this, puff, it restarted, and then it wouldn't even start Windows XP (but it POSTed perfectly).
I've tried all kind of configurations and all. I even lowered the multiplier to 8 (I was using 400x9), leaving the same core voltage in the BIOS (1.4v in BIOS, it would reach 1.296v in CPU-Z at full load), and it happened almost the same: it restarted when I started organizing the files to publish after it successfully passed Prime95 test.
Please, I need some help here. Does any of you has a Gigabyte GA-P35-DS3L motherboard? I assume that's my problem here, but I just bought it, and I've seen good results for other people. I do NOT want to change my board...
Thank you in advance.
I have the exact q6600 and Gigabyte GA-P35-DS3L system with OCZ DDR2 800mhz memory.
I am very easily able to oc to 3.0 stable:
1. Turn off EIST (in Advanced BIOS screen)
2. Turn off Auto CPU Fan option (so it is always on not whe the cpu gets hot only)
3. go to M.I.T:
- 9X333
-PCI-Express [set this to 100, never set it to default when OC'ing)
- Performance enhance[standard]
-System memory multiplier [2.50v] - check with your memory to see required voltage, Gigabyte's default volt for RAM is quite low
- set CPU voltage to 1.26 [this pretty much depends on your cpu] - what does the "default voltage" shown at the bottom of the MIT screen ?
I've already done that. :(Quote:

Thanks for your reply.
IF I am to buy a Q6600 in a couple of weeks, what shall I look for?For now, I only know to look for SLACR for G0, how about the B0 stepping, I am confused.I made a mess at a good forum when asking for the right MB for Q6600+TR ULTRA 120-E, shall it be 8 phase ASUS P5K-E or 6 phase+6 interpolated GB-X38-DQ6...There is a huge price difference here, more than $ 100, and I heard that a Q6600 cannot make more than 8 X 485 on air...

You can already get the Q9300 from Tiger Direct and it should overclock better than a Q6600, IMHO. Of course if you have a Microcenter near you it is hard to justify paying $100 bucks more for the new one when you can get the Q6600 for $200. But if you are going to be paying between $225 - $250 I would just go ahead and get the new one, again, just my opinion.
Utnorris
How exactly is a Q9300 with a multiplier of 7.5 going to clock better than Q6600 G0 with a multiplier of x9?
Well actually, the Q6600 costs about $ 350 in Bulgaria.And I have read some dissappointing reviews of Q9300.Q6600 has better OC percentage IMHO.
Exactly.
The Q6600 can be had for as little as $200 at any B&M Microcenter in the US and has better OC potential than perhaps even the Q9450 due its multiplier. Also, let's not forget the degradation issues experienced with the 45nm chips. The Q9300 and the Q9450 will certainly hit modest OCs speeds with great ease. However, to expect a Q9300 to hit 3.6ghz is pushing it, and while the Q9450 should do 3.6ghz on air with a 450mhz FSB, getting one to 4ghz seems to be out of reach in most cases.
On the other hand, seeing a Q6600 G0 hit 4ghz on water, while certainly a great feat, is not uncommon.
LOL, dude beside showing off some super PI do a few hours prime :>Quote:

Just picked up another q6600 from microcenter of batch L744B065 package date 1/08/08. Won't have a chance to plug it in and see what the VID or OC potential is on it till next week when my MB arrives.
Not showing off :rofl: , (time is crap anyway?) as i said i only had about one hour that day so PI had to cut it.Quote:

I guess the zalman will meet the bin :shrug:
I've been running my G0 24/7 at 9x400 1.6vcore for 6 months now, temps max around 65C and it took 1.6 to get over 48hrs quad prime stable.Quote:

Just started testing my new Q6600 with Xigmatek S1283. Seems to clock easy enough, but I have some concerns on temps.
Idle @ 3600 (9x400) on 1.350v (in Bios)

Prime load went over 80c after a few minutes on CoreTemp so I shut it down.
Idles 33c-37c at stock speed on 1.200v. Gonna try to reseat the HS later and see if temps do better.
Load @ 2400 on 1.200v
