Alright... I've been running an E6600 L640B batch for 4 months now, it was a retail late batch and frankly, it sucks terribly... 3.4GHz was my ceiling @ 1.60vcore. My system is cooled fantastically as well, so the processor is just a boat anchor. I went to fry's and talked to the component guys (which, interestingly, are very very knowledgeable about OC'ing) and they were nice enough to rummage through their E6600 inventory and pick me out a 3718A201 batch. He seemed convinced the B batches OC'ed better than the L batches... and I disagreed.. after the 639 batches production was switched over to the new production facility in malaysia and those have proven to be terrible... as my 640 shows. The sweet spot from my memory is the 627-632 batches.. I have yet to open the retail box (as I then own it). I don't have a lot of experience or knowledge of these even later model processors... this one is manufactured in the costa rica plant (?)

any ideas?
 
1.6vcore??????


That's WAY too much man....1.5V is pushing it already. With 1.6V you need a sweet mother water cooling setup or phase change.

I have a sweet mother water cooling setup... max load temp of 38c... It's perfectly fine. :) Currently I'm back at stock 1.325 since I'm only running 1 stick, and my processor is at room temperature under load, pretty funny.
 
Should've checked your sig....my bad....but does 1.6V even give you higher clocks than 1.5V in first place? I'd think that you hit the wall of your proc, no matter if on 1.5V or 1.6V.

Anyways, if you're planning on getting a different Proc, then why stay with the 6600? I'd pick up a E6750 for cheaper and (from first tests) it overclocks a hell lot better than even the early E6600 cores.

I havent looked in to those at all? Are they a lower stock clock or less cache or something?

I'm researching the performance of this new costa rica E6600's now.. looks like some have got to 3.5GHz @ 1.45vcore... which is promising.
 
It's a possibility... :(

Many mobo manufacturers have come out with Bioses for their 965 lineup to support these though. Might want to look into it.

<edit> extremesystems.org has the board running with the new E6x50 processors without any problem. Appearantly the newest Bios adds support for these procs.

Pretty sure it isn't supported yet. But yes, the DS3 3.3's have the support added.

the review basically says they are quick, but the new bus speed really doesn't do much.. they get it to 3.6GHz but any decent E6600 that's cooled well can surpass that easily (I unfortunately have been unable to get a decent E6600)

I've been unable to find any info on these new costa rica E6600's
 
Mine will do 3.6 at 1.45 v. I forget what batch it is but it's a week 38.It idles at 29c with an Antec 900 case and a Tuniq Tower cooler. I can get it to boot into windows stable at 3.85 but it's not prime stable plus i can't keep my timings of 10 3 4 4 1t at that speed so i keep it at 3.6 450x8. It will go higher no doubt but the timings to me are really important. Lover this chip,this is my first good luck buying a cpu that oc so well. This on a gigabyte p35 board.
 
holy sh**, that is an incredible overclock. I have one of the ds3 3.3's and yes they do have support for the 1333fsb procs. They seem to have a nasty issue with pcie overclocking. you have to push the pcie bus up to around 104-108 to get it to stay a x16 lane, otherwise it drops to x1, which blows. bios f12 was supposed to fix it, but apparently has not. and that sucks about fry's return policy, i do my chip shopping at microcenter, the employees are idiots and think nothing of me bringing back 2 or 3 chips after they had been installed and tested. Just talk over their heads and they give you the return, it is wonderful

L638? what batch exactly?

Has anyone tested these Costa Rica E6600s??
 
Im jumping around forums looking for info on these chips because there is so little of it. This is what Ive got if it helps any.

Im testing 3.4 at them moment with 1.39v set in the BIOS but its not quite that high when you factor in the vdroop on my evga 680i. If 3.4 checks out after about five hours Ill move to something faster.

Ive got a tuniq tower and ambient is probably right around 70f, load temp is 43C after about three hours of Orthos.

Ive never done any heavy overclocking so someone with more experience will have better luck.

There is a thread at XS about the costa rica chips and I guess people are getting results similar to the old Malaysian chips except with lower temps.
 
Im selling my E6600 ( L632B172 ) to somebody @ XS but if it doesnt go through Ill let you know.... Im watercooled too and 4ghz is no problem, recently ran spi 32M at 4100mhz, played UT2004 @ 4ghz.... And ofcourse 4ghz Orthos on air when the weather was colder back in feb ( see database ).... 3704mhz @ 1.43v....

:eek: good god man 3.4GHz @ 1.39!! Maybe I will break the seal on my costa rica E6600! Funny this is, my E6600 is 3178A210 so I'm really interested in your results. My L640B only made it to 3.4GHz @ 1.60v and it's dying.

luihed... let me know.. I probably won't pay what you want for it seeing as I already own 2 E6600's, but if your willing to let it go for something reasonable, I might.
 
Just an update on mine. 3.4ghz was fine for 5 hours in Orthos. Given, I should run at least eight hours, but that will come when I get this chip to a higher speed. Ill move onto 3.5 tomorrow. Here is a picture of voltages Ive get set in the BIOS. Its set to 1.39 but "current" always reports lower.

hey smeed! you follow me around! :)

have you tried taking some manual readings with a digital multi meter? I think I've almost been convinced now, and I might open the box on my CR E6600 now :X I'm setup to go big too, so rest assured I will definately floor it.
 
Na I havent checked it with a DMM. Im not sure how actually, but maybe Ill read up on it and find out whats really going into this CPU.

BF2 was rebooting my system while loading so Ive gone back to run Orthos some more. Im pretty sure my problems are from me running the memory on an odd divider which the "unlinked" option set. Im going to run orthos small FFT priority 8 overnight just to rule out the CPU though.


If your going to open the box, make sure you push it hard and share the results :) By the looks of it, most are having good results with them and I wonder how it will stack up to the e6850 in your sig.

I must say this most recent turn in events on the late E6600 batches was most unexpected. I'm probably switching out this E6600 CR for an E6850 later today, as I think it would be a better path for my hardware, since my memory can handle the higher bus speeds with overclocking. I'll keep this forum updated.
 
Yeah thats probably a safer choice. Ill keep pushing this CPU though. Its 8hrs orthos stable, tested overnight. I might take a break from overclocking for a few days because I havent had much time to play some games and just have fun.

haha no shit, I feel like I'm running a business here... I spend all night adjusting voltages, reading shit, taking down data... and what's the point? I mean, it's to play games, right? :)
 
All the fun comes when your done and you see how much you have gained :) Its when you get 7 out of 8 hours of orthos done and your stuff fails is when its a PITA. Ive never done this before so at least Im learning, for you and most other people its probably a lot more draining.
