ok. I see. I remember someone doing this a while ago. It didn't seem like the returns for dropping the multi were worth the time and effort. I haven't seen anything recently on this so I could be going from dated material.Quote:

I just sold a Q703 batchcode 6300 that was attrocious. 3GHz was a struggle. I got it off of ebay and was under the impression it was an L629B as that was what the seller had posted in the ad. I contacted him and asked if he had others and if he would swap with me. Amazingly enough he had both L629B and L627A so I opted for the A. It is on its way and I am hoping this will give me some serious OC as I have seem great results from others with this batch code.
I have an E6600 L644G. 3DMark stable at 3,9 GHz on air cooling and ~1,6 V. Runs really cool, about 10 degrees Celsius cooler then my old L625A, and about the same as my old L633F.

My 711A is currently doing 3.1GHz on 1.35V using low-end air cooling. 24 hour orthos stable. Was able to boot no problem @ 3.6GHz, 1.5Vcore. Haven't tested that much though.
Are you able to drop your multiplier and get the same or higher FSB and memory clocks? Maybe you need to tweak some other settings like your NB/Memory voltage or memory timings. Try different memory dividers as well.Quote:

Now what is confusing me is that CPU-Z says my Core speed is 3400mhz yet orthos and coretemp 0.95 both say 3825mhz. I know my CPU is running at 3400mhz..... odd.
When i simply tried to ramp up the CPU to 3.4ghz.... it would fail within the first two minutes on Orthos. So i think i'm heading in the right direction now.
Here is a screenie so far.

OCCT? CPU testing program? I don't know the highest Orthos stable speed. I think it is somewhere between 3,7-3,8 GHz.Quote:

Right now it runs at 3,4 GHz and 1.44 V. I think I can lower the vcore without any problems, but I like to have some margins. With my Tuniq on lowest speed, 900-1000 RPM, it stays around 50 degrees on load.
Im water cooled and my E6600 is hitting insanely hot temps, low to mid 50s. Im gonna lap it today. Boots at 3.8ghz, max prime stable so far is 3480 @ 1.47v. This is better than my E6420 which needed 1.525v to hit 3480, (and hit a wall at 456Mhz FSB) but the temps were alot lower around 45c.
Anyways, I checked the base and its like a spoon so I think a good lapping will drop my temps significantly. Hoping I can overclock higher with less vcore if I strip off some of the layer between the core and the top of the IHS. Gotta hit the hardware store for some 300, 600 and 1000 grit sandpaper.
Starting to test an L652B112 now. Will update with some results shortly :)
I believe it has something to do with the strap. Don't worry about Orthos and the coretemp reading of the CPU, it's not seeing the mult dropped, just the default. Orthos thinks Im over 4000 Ghz, oh how I wish :)Quote:

EDIT: Running Orthos Large in-place FFT's at 3.3Ghz stock vcore. Is it truly overvolting or do I have a golden CPU?
If it doesnt seem to change, try resetting the CMOS. I doubt you are still on stock. Using Everest will show the proper voltage I find. On Auto @ 3.5 my cpu was getting 1.59v - I was like wtf. its prime stable at 1.475v, so 1.59v is a bit extreme. I wouldnt leave anything for voltages set to auto, makes me nervous that it wont just spike it and fry something.Quote:

Quick question from the intel ignorant (me)...
In my bios settings, what is the SPP <-> MCP Reference Clock? I have it set to Auto. Will adjusting it help out overclocks? I've kept all my PCI-E settings at 100mhz.
http://img.photobucket.com/albums/v3...xKok33/3-1.jpg
Boot at 9*333mhz, done more tests at 3.6ghz 1.43v and this setting is fully stable. 3.7ghz takes a lot of voltage to get stable. CPU is very good at low-medium vcore which is nice for 24/7, however it's not a record breaker on air. Will test phase next weekend or the weekend after (my unit is getting fixed atm). Overall it seems like a very nice CPU, certainly as it's relatively new :)
@Andrew, sorry mate can't help you :(
fpo/batch L644f @3700Mhz vcore 1.6 (actual) water cooled 19c-20 idle 44=45c load w/core temp .TAT shows 1-2c higher
http://img142.imageshack.us/img142/1...ilowesthn8.png
I know this is not extreme OC'ing, but I just got a L640A823 E6600 and I've got it folding stable 24/7 at 1.335 vcore at a 3.0 GHz OC' and it seems to run cooler than my other E6600 L632B444 OC'ed to 3.2 GHz and a vcore of 1.40v (maybe a degree or two, I know more clock and more vcore) Both chips with only 1 hr Orthos (I'm impatient anal) run about 20c idle 32c load with an ambient of about 21c (please don't anyone tell me about the idle temp being below ambient with air cooling, I'm only using the software temps as a caution my HSF or case fans don't go out) and then I have to boot back to Ubuntu 64 to fold. So far so good, I think folding puts as much strain on the cpu as Orthos anyway. It's crunching a p2609 at a tpf of about 13 mins, it's only on frame 19. ("cool city" so far)
Well I lapped my E6600 with 320, 600 and 1200 grit. Didn't go for the perfect mirror finish but the base is level now. Took about 45 mins at 320 grit to remove the spoon effect and actually show signs of sanding on the middle of the chip. The chip was really bad.
Before, max stable Orthos was 3480 @ 1.475v.
Now I'm running 3500 (389x9) @ 1.46v 5 hr orthos stable. Temps are 43-44c load. Much different than 52c at 3480!! Even trying to force 3.6 @ 1.55v while not orthos stable loads about 48, before it would hit 56 - 57! Overall lapping was worth it, unfortunately the chip isn't much of an "golden" overclocker. I was hoping 1.5v would get me 3.6v.
I may lap my E6300 and toss that back in. It does up to 3590 @ 1.375v and 3604 @ 1.45v, while the E6600 3545 needs 1.5v and it just gets worse very quickly. I cannot get 3.6 orthos stable and thats all I was hoping for. :rolleyes:
My hangup is the 4MB cache. I want the extra cache, but am uncomfortable giving the E6600 so many volts when the E6300 runs higher on less. However 1M is almost 2 seconds faster on the E6600 (16.2 vs 14.2 seconds)! I've gotta test 3dMark and see if there is any notable gains while using the E6600 over the E6300, cause one of these chips has to go!
Has anyone else tested an E6400 or 6300 vs. one of the 4MB cache chips?
Yeah the vcore thing is a quandary. I have a E6420 OC'ed @ just 3.0 GHz, vcore 1.35v (in BIOS) 19c idle (screwy Core Temp) and about 35c (hopefully less than 40c) load, my ambient is about 21c. Results are with Orthos for only 1 hr, I fold SMP in Ubuntu 64 6.10 plus I'm "patients challenged". I think folding puts as much strain on the cpu as Orthos. Both of my E6600's run about the same temps with the same vcore or a little more. One E6600 is OC'ed @ 3.2 GHz (the hotter one, D'oh) and the other E6600 is OC'ed @ only 3.0 GHz. I have my E6300 in a Asrock 775DUAL-VSTA mobo ATM and it's only OC'ed to 2.1 GHz. (the 775 is not too good for OC'ing, but IMO a great interim board)Quote:

Anyone have any suggestions? maybe just a bum chip?

(figures, I never get good oc'ing chips it seems.)
I'm currently hitting 3.44 Ghz on my L644G that I got on Friday. I really want to hit 500 mhz fsb, but I don't know if that's going to happen :(.

Sounds like you found your sweet spot. It gets to a point where you need to bump up voltage quite a bit to get little gain. Personally, I'd leave it at 3.5 GHZ if I were you...:)Quote:

That is all I wanted to 3.6ghz, I had it at 3.6 with 1.48 loaded tested it 12 hours orthos blend a week or two later test it again and it fails almost instantly :confused:
I still dont understand why it would do that, not like my cpu is degrading after a couple weeks ?
Anyways yeah I think 389 is going to be the sweet spot for me just went 6 and half hours blend so I dropped down the Vcore twice and she failed after 12 minutes so I bumped it back up 1 and we will see how she go's, if it can last I will bump my ram back up and see if I can get orthos all night :)
Yes check this out one of my earlier posts
I am stable at 3.6ghz now I am not with the same settings ? anyone guess whats up
I don't remember, but I think somewhere around 1.40 volts.Quote:

Cpu was week44 B2
Even my 2times cheaper E4300 does better. :D
3250mhz with stock volts and 1,55V to get 3600mhz :cool:
Max on my E4300 is 3900mhz with 1,7V
Do these temps seem right to you?
1.43-1.45V 400x9
32C idle / 65C full load?
do you think its just bad contact or does it seem normal to have it jump that high?
I am using air cooling w/ a scythe infinity.
I've just recently had 2 x 6420s and now a 6600 and none of them will run 3.6 Ghz Orthos stable. These latest chips are a disappointment to say the least. Even water cooled and up to 1.65v - 3.6 is a no go, it's stable and will run super pi but it's not stable enough for orthos.
I would buy one that has been overclocked and tested here on the forums.Quote:

Half of them dont know what the number is, then 1/4 of them dropship them and have no clue. Your best thing is to get on that is know to be a good chip.I hear tank guys going to get some of the older chips like l628b or something along the lines of that. But not sure what the price will be. It will be more then $230 though. Good luckQuote:

I have up forsale today an Intel Core 2 Duo E6700 Engineering Sample. Its a great overclocking. I no longer need it so I am letting it go for a great price of $300 shipped in the US. I have lapped the cpu IHS flat because it was concave.
Great overclocker and has reached 4.6ghz on dry ice and a 975x motherboard. It is a great overclocker. Unfortunately I lost the hdd with the pics before lapping. I have these from when it was lapped. Should hit 3.7+ daily on a good water setup.
perhaps this will help alliviate any angst created by the latest batches from intel :toast:

I know, it's not very impressive. Took 1.46V, vdroop to ~ 1.44 and its rock solid 24hrs orthos. I will by giving it a go for the ceiling, but will probably be limited due to my lack of active cooling for NB/SB and my not so well ventilated case. Anyone with some suggestions on the volts such as VTT/ ICHIO and VMCH will be appreciated.
FWIW

I just got a l644f from newegg on my E6600 after getting a l644g on my E6420. Just my luck. I cant find anything on the l644f tho.
After some disappointments with an E6600 and E6420 L644G and only mild success with an E6420 L651B I decided to buy an E6600 L629F from Tankguys. First thing I noticed is the VID is 1.2375 instead of 1.325 or 1.350. I got to 3.3GHz before I had to bump the vcore for stability (relative as I only run orthos small ffts for 1 hour initially). Idle temps for the L629F are 28C whereas the idle temsp for the G and A chips at this vcore was around 22C. I finally got to 3.6GHz at 1.475vcore but the problem is now heat as these chips run siginficantly hotter than the A or G chips. This chip acts very much like my old Xeon 3060 in that it tracks well but has heat issues and to remedy that on the Xeon I had to lap the IHS as it was quite concave. Initial impressions are that this chip is less of a pain in the ass to OC to high FSB than the current chip available so I believe it is worth the extra $$$ for less headache in this area. I will lap this puppy and then put it under water to see just how well it performs.
I also have an L629B coming Monday, from Tankguys, so I will get some initial impressions from that chip and share how it works. As of right now I highly recommend the L629F if you can get one but be ready to lap it and if you put it under good cooling I am confident you will be pleased with the results.
