Newer batches of Conroe OCing poorly?

[CedricFP]

I recently saw a few threads where people have mentioned this observation...

But I can't see any reasoning for it. Are Intel binning their chips higher, so E6600's no longer have that much OC potential? Is that being saved for E6700 or X6800's?

Or are they simply using cheaper (or worse) materials (silicon?) because of the huge headroom in the first 30 or so weeks?

[safan80]

I ordered a Xeon 3070 it'll be here friday so we'll find out.

edit: as a side note I had to use 1.55000 volts to get 3.3Ghz with my week 42A.

ur talking about E6600 right?

[largon]

Generally speaking Conroe has had a huge scaling potential above the rated speeds. Intel ofcourse doesn't get paid for huge OCs but the amount of sold chips. They could've tweaked the fab process to favor yields instead of scaling.

[safan80]

ur talking about E6600 right?

yes the one in my sig "6600 L642A289".

I posted it in the oc database if anyone cares.

WOW 1.55? I was thinking of selling my E6400 that will do 3.2ghz @ 1.35-1.375 now im reconsider keeping it.

[CedricFP]

I just bought a E6600 week 27B than can do 3.8 @ 1.42 orthos stable on Air... it's a much earlier week than the ones that can be bought now, and seems to overclock better as well.

The yield idea makes sense. It's a real shame for OCers, though.

[Rickster_64]

I also debated on buying a 6600, but if this is true I will hold onto what I have.

[Stelios]

I saw an E6600 L707Axxx here in Hellas ... I'll try to test it .

[Skyline GT-R]

I think the answer is pretty simple, Q6600. They need the better chips for there quad core's.

[argylesocks]

edit: as a side note I had to use 1.55000 volts to get 3.3Ghz with my week 42A.

and i thought me having to go to 1.475v for 3.3 was bad....

voltage needed seem to increase exponentionally as i increase fsb...

[ahmad]

And we don't have anything that can OC quads properly...

[fhpchris]

uh, the EVGA 680i and the P5B Dlx work perfectly with the quads :)

[Rickster_64]

I need to dig out my exact batch but its week 32 from what I remember, and I am stable @ 3300 with 1.3V. Factory Intel cooling. Sounds cheesey but sometimes I read reviews on newegg.com as people post results from recent purchases you have another source for how the newer cores are clocking.

[uOpt]

I believe that they reserve the best dies for the quad-cores.

Since they have to put two dies into one CPU case it is very important for them to do so at the lowest voltage and heat, which basically means the best clocking dies.

Now, if you would buy a QX6700 and made two Conroes from it... :)

[NaeKuh]

fry's has a few more 31B batches at the burbank store CA. The manager was nice enough to let me hand pick mine out of his supply after a quick non flat ihs proof.

As of friday, when i went, i saw a total of 8 oem 31B batches.

Mine DID (b4 bios flash) 3.6ghz on 1.387 Its having problems at stock after the bios flash.

But if anyone is interested, id hurry and pick one up if your still looking and in the area.

Should warn you guys tho, she runs a bit hot compared to all the other C2D's ive seen. Definitely a lot hotter then the A batch, and even some anandales.

[Barnsley-Bill]

I.ll have to dig my box out and see what my e6600 is ive got it runing at 3.7~ 1.56v my QX6700 should come sometime this week then i.ll try that :).

[ownage]

newer batches are b!tches, :P
They just dont clock, i've seen xtreme users who only could hit 3,2ghz with xeon 30**, and way to much volts.
I'm glad my week25 clocks good :P
i believe they last good batches are week 31, maybe 32.

[EZClock]

My E6700 only does 3.7ghz @ 1.54v orthos. It's week 29 :(.

[oqvist]

What week would you estimate an E6600 I am buying that is sixth month old is?

[mag|c]

I found out my DELL has a 629B E6400 (witch is suppose to be quite ok) - and the P965 board inside has ZERO oc options, gee that suck bigtime!

[ziddey]

hmm if there's a bios revision for the board that gains support for 1333fsb e0 conroes, then you could try modding your chip to run at 2.66ghz

[Heidfirst]

uh, the EVGA 680i and the P5B Dlx work perfectly with the quads :)
& the QuadGT with the B06 "R" modded BIOS.

[Jedi2155]

Try to sell that to someone, the B's are nice :D.

[Death^Dread]

or buy a new computer, swap in a crappier processor, and sell the pile of lard that goes by the name of "Dell"

[Chewbenator]

I have a week 28 I believe, and it took 1.4v to get 3.2 Ghz stable.

edit: whoops, forgot to mention it is a 6400.

This was bought from zipzoomfly the week or weekend that the conroe line was released.

[CedricFP]

The week 28's were supposed to be good, but within-week fluctuation of OC potential is understandable.

What confuses me is the downward trend of new weeks. Perhaps it is all for the quad cores.

Yeah, I was happy I managed to acquire it. Thanks dinos ;)


How about latest 6300 or 6400s?

I have heard that the newer (released or soon to be released) Allendales are true allendales, not nerfed Conroes, and that their oc potential has been poor.

great, cause my DS3 died and took my 3.6 Ghz 6300. I hate Gigabyte and will never use their products again. I'd advise the same for any one even considering a new rev3 GB DS3. I have another chip coming which I am afraid wont even get close.

I wouldn't set it in stone just yet. You may get a good chip ;)

[bito]

I've had two E6600's.....first one was week 28A...ran 3.6ghz at 1.48v.
My current one is a week 32A....running at 3.6 with 1.4v.
Haven't tried for any more out of it yet....this seems like a sweet spot for these processors.

[Omastar]

My week 30A Xeon 3060 will do 3.6GHz at 1.375v, Orthos/gaming stable. I wouldn't doubt the newer batches suck as Intel wants the biggest yield possible from C2D.

[Ruslan]

I went trough 2 E6400 (Sold the old one now on the second one) that do 3.2 below stock and I thought I could do better. I'm going to stick to this one for a while now that I hear about this.

[SLI POWNAGE]

Since they have to put two dies into one CPU case it is very important for them to do so at the lowest voltage and heat, which basically means the best clocking dies.

yup, nothing on 3 boards now with 2 different PSUs. Got the new CPU in but it came after I left for work. DO NOT BUY GIGABYTE.

Turns out my DS3 ate a stick of OCZ PC2-8000 - I can get that replaced. My CPU is fine. However 645a E6300 couldn't even run 2.8 (400x7). The new chips that I've dealt with stink.

Im happy my 3.6 E6300 is still alive!! Strangest thing though with the bad stick installed 3 different mobos wouldnt even beep just boot without post. Even removing the stick from the board, it will beep - I cannot imagine how a stick of memory can get fried so badly it wont even beep like it didnt see any memory...

[G.Foyle]

Looks like weeks 32 or 33 were last good weeks, at least for A stepings. This may be different for different fabs.

wow. just wow. I had the same exact deal with my ds3 and a pair of buffalo firestix (d9gmh). only in my case, it ate both modules.

I was pretty certain that it wasn't the cpu though since I haven't seen a cpu blow up on me ever *yet*.

I guess a good way I've found in checking ram is this: If you have no modules installed, and it gives beeps, then it means that the cpu works. If no modules are in and it still doesn't beep, then it's something else.

friggin ds3. I was almost thinking of pulling my ds3 back from the closet to run again. thanks for steering me straight :)

Well my DS3 is completely dead now - wont even start. But the P5B-E and P5B Deluxe would just power on and no beeps, nothing. So after the 2nd PSU, 3rd Mobo and 2nd CPU I figured wtf and pulled a stick... it beeped. Swapped and put the other one in, nothing. So I definitely have it narrowed down to 1 bad stick. Why the Asus boards didn't at least beep made me think it was PSU or CPU related. Sometimes troubleshooting sux and man it's expensive!!

Anyone interested in an Enermax 720watt Infiniti PSU for about $190 shipped?

you guys have successfully scared me off the ds3.so in a couple of days i will instead be getting the asus equivalent, the p5b-e and an e6400 :cool: .

I have a p5b-e, only thing that irks me is lack of vdimm. Just ordered and installed a refurbed p5b deluxe from Newegg for $109.

[RAMMAN]

thats okay, i only need 2.2v for my ram, at least for now.the p5b deluxe is too expensive for me.

I received a 44A E4300 yesterday, it is the worse clocking C2D i've owed. Needing 1.45V just to post @ 3000MHz... My 41A is a much better clocker, and it still is bad.

[RAMMAN]

The p5b-e only has 2.1 Vdimm though

the ds3 is too unreliable for me, the p5b deluxe is too expensive and i hear the abit ab9 is a very poor overclocker, and i assume the gigabyte s3 is similar to the ds3.so i guess im stuck with the p5b-e.no other choices in my price range from the shop im buying from.hopefully my ram can at the very least run at its rated clockspeed+timings with only 2.1v.

That sucks on for the 44A :(

What kind of overclock can you get on your 41A? how much voltage do you need for 3.2ghz?

[ziddey]

RAMMAN and dnottis, I've figured out vdimm pencil mod on p5b vanilla. I believe it to be similar on p5b-e. Depends on your revision though since layout on my vanilla is different from some

I also tested E4300 same week as yours, Q644A, at 3.2Ghz, have to pump vcore more than 1.55v to make it stable. :(

Same here. People saying 3.2GHz takes 1.5v+ is ridiculous. I can do 3.2GHz at like 1.35v.

[[XC] riptide]

Looks like most of us W29-3X'rs got lucky.

[Cracker]

I guess I'm glad I got an early Conroe chip (week 24 E6400) and an early DS3 (rev 1.0) because I've had nothing but good luck with these two pieces of equipment. I run 3.2GHz 24/7 with the only voltage change being the vcore to 1.3125v and all the other voltages (besides the .1v bump my RAM needs) are stock. It runs 3.4GHz with the same voltage but my crappy Arctic Cooling Freezer Pro 7 can't seem to keep it under 60C(load) when it's set at 3.4 so 3.2 is the speed until I upgrade to the Tuniq or Thermaltake Ultra120 and a fat fan.

Maybe being an early adopter pays sometimes? The later C2D chips seem to be hit or miss as do the newer DS3 revisions. :confused:

I'm hoping to grab an early Q6600 when those get cheap. ;) Apparently the first chips out of the gate have to be good to help sell the more marginal chips to follow. :p:

[Yay for Cheese]

Are the latest 3060 also pretty bad OCers??

[Postal Dude]

Might be able to post some results from my 6400 L630F later tonight. Going from amd to intel tho. So gotta reinstall windows and setup all the software crap before i can do anythin.

[Kingcarcas]

Looks like the poor guy gets screwed by Intel......i guess i'll just wait for dual core K10 and buy some new cymbals in the mean time.

[gOJDO]

Why are those complains about DS3? What's the problem with it?:confused:
I have a DS3 and a L628B183 E6400.
It needs 1.4v for 3GHz and 1.46v for 3.2GHz stable. It needs 1.52v to post at 3.4GHz and it is not stable at that frequency even at 1.55v.

After reading how a lot of people are pushing their E6400 to 3.2GHz+ stable at 1.3x voltage I was thinking to replace my E6400 with a one with L632A942 stepping. What do you think about this stepping? and do you think that its a good idea to replace my E6400?

[parodius4]

Gigabyte DS3 rev 1.0 works very good for me. Very stable and FSB 490+ (RAM is limiting) w/out touching the NB/MCH voltages.

Have heard only good things about Gigabyte P965 mobos until now.

This is exactly what im seeing on my DS3 3.3 rev b2 which is about 2 weeks old. :slapass:
Very disappointing.

[starostise]

i tested some E6600 with following steppings:

L629B479 | 3500MHz | 1.50v | aircooling - tuniq tower
L629F204 (pack date feb 2k7) | ~3850MHz | ~1.55v | aircooling - tuniq tower
L635A418 | 3700MHz | 1.52v | aircooling - tuniq tower
L637A464 | 3700MHz | 1.58v | aircooling - tuniq tower
L639A604 | 3600MHz | 1.58v | aircooling - tuniq tower

so for me, newer stepping are bad clockers, but it always can be exeptions. and we can find bad clockers with early steppings.

Yeah, it seems everything below week 32 (?) tend to be decent clockers. Afterwards, reports get hazy but there is a definite downward trend.

[seedomo]

Very interesting results as I try to get to 4GHz.
Cooling = Swiftec MCW6500 TEC 226 watt TEC
MB = EVGA 680i
Pelt PSU 300watt Meanwell at 13.8 Volts

Strange results in temps:
Week 44 chip @ 3.7 GHz:
Needs 1.6 Volts for stablity. temps -8/35 (idle/load)Celcius Using Orthos Small FFTs
Week 29 chip @ 3.7 GHz
Needs 1.45 Volts for stablity. temps -9/41 (idle/load)Celcius Using Orthos Small FFTs

Sooooo... why are the temps the same? If the needed voltage is less on the Week 29 chip, shouldn't the temps be lower as well? Can the amperage be different on the two chips? Amps*Voltage=Watts

One more thing is that the Week 29 won't even post any higher than 3.75 MHz even at 1.685 VCore but will run stable at 3.50 using only 1.5 volts!

Version: D86354 - 001
(pack date 02/20/07)

made in Malaysia

...so that sounds like week 52 of '06?

[ziddey]

2006 week 52 (last week ;)) a

[OV3RCLOCK3R]

I've got a week 25(a) 6300, takes 1.4v under load to do 3.6ghz on air, 1.45v for 3.8ghz :D

[Lev]

how is l32a batch? ive got a 6400 have not tried clocking it yet waiting to buy a hsf

[keldererik]

I've got an E6600, L635A533, doing 3.2GHz at 1.28V (1.240V in Windows). Orthos stable for alot of hours.

So it seems this price drop comming up ain't that good after all eh? :stick:

[lowfat]

how is l32a batch? ive got a 6400 have not tried clocking it yet waiting to buy a hsf
I had a 32A E6300 that wasn't bad. It would do 3150MHz with 1.2Vcore on stock cooling.

[bito]

Got my L32A 6600 doing 3Ghz right here at 1.168v Orthos stable 18hrs + :)

[afireinside]

Very interesting results as I try to get to 4GHz.
Cooling = Swiftec MCW6500 TEC 226 watt TEC
MB = EVGA 680i
Pelt PSU 300watt Meanwell at 13.8 Volts

Strange results in temps:
Week 44 chip @ 3.7 GHz:
Needs 1.6 Volts for stablity. temps 8-35 (idle/load)Celcius Using Orthos Small FFTs
Week 29 chip @ 3.7 GHz
Needs 1.45 Volts for stablity. temps 9-41 (idle/load)Celcius Using Orthos Small FFTs

Sooooo... why are the temps the same? If the needed voltage is less on the Week 29 chip, shouldn't the temps be lower as well? Can the amperage be different on the two chips? Amps*Voltage=Watts

One more thing is that the Week 29 won't even post any higher than 3.75 MHz even at 1.685 VCore but will run stable at 3.50 using only 1.5 volts!

The IHS on the week 29 probably sucks ;)

BTW damn nice temps for using a TEC with an mcr220

[Psyire]

Got a E6600 - 30B doing 3.4Ghz Orthos stable (27hrs+) @ 1.32v and 58*C in Coretemp (scythe ninja) It's stable at 3.5Ghz and 1.35v but temps hit 60*C so I backed it off a bit... With water cooling or more aggressive air cooling, I'm sure this chip would do 3.8Ghz or better, no problem.

very nice vcore that's one thing the P5B dlx has going for it.

[drunkcarlos]

has anyone tried a week 45 6600 yet?

[Super strokey]

hmm all of this right before a price drop... doh. Maybe i shouldnt have waited lol

[joking]

My 6300 week 41a need 1.4v to run stable at 2.8Ghz :(

[safan80]

hmm all of this right before a price drop... doh. Maybe i shouldnt have waited lol

you could probably get a Xeon 3070. mine is a 29B that I got from the egg.

[zodden]

My chip it's worst ;)
E6600

L628A302 - IHS
2L626535 - PCB
A0905 - PCB

3,2GHz 1,435V
3,6GHz 1,645V (full stable, Orthos over 4h)

This a winner :)


That does not sound like a winner to me. Don't get attached to your chip as you won't have it for very long. Unless of course you settle for 3.2@1.43 which is a high voltage for a not very impressive OC.

[computerpro3]

thanks to this thread I ended up spending way more than I wanted to. Due to a lack of good Ocing e6600 in the market I had to spend a little under twice what I had originally planned.

The upside? I have a E6700 Engineering Sample in the mail that does 4.4ghz Orthos stable on phase change, 4ghz on water with 1.55v. Now THAT sounds like a winner.

What is the max volts I should you when I purchase the CPU to make it last 2-3 years ?

[slim142]

Mines will only boot at 400Mhz FSB with 1.58v but is super unestable. even at 1.60 is very unestable.

interesting !

[I)ickie]

One possible explanation for the poor clocking could be the removal of the soldered IHS's as explored but not confirmed in this thread (http://www.xtremesystems.org/forums/showthread.php?p=2108958#post2108958)
The higher temps associated might be leading to worse OC's

[safan80]

interesting !

not really I have doubts on it's ability to OC.

3600mhz @ 1.45v cooled with Scythe Infinity
1h30 of Orthos and still running! :)

will up the clock soon to find the limit and will try to find the FSB wall....my old one wall at 520fsb air cooled....will see if this one will be candidate to Dry Ice ;)

[GMX]

Just received L707A.

[ziddey]

:eek: how is it

[slim142]

Im planning on buying another Conroe. I dont know if I should try the E6600 or the 3060. And I dont know if I should buy from Newegg or ZZF or Excaliber etc.

What you guys recommend? I heard 3060 from the egg are the worst right now.

[shiyan]

oh damn

looks like I might as well get a E4300 now, try my luck, and wait for cheap quadcores to appear later in the year

[drunkcarlos]

yeah the e6600 I picked up is a L645G356.

Gonna try to put it together this weekend as all my hardware finally arrived.

I'm starting to think I should have got one earlier... oh well

Ditto. I ordered an OEM chip from TigerDirect this week (decent deal, BX2+e6600 for $449, I couldn't wait until end of April as I have the week of the 16th off from work and wanted something to mess with), and got an L707A yesterday. I got the system up and running last night and am going to mess with it some this weekend. Love it when a PC goes together perfectly on the first boot... My goals are mild, 3.0-3.2 GHz. If I can do that on DDR800 setting (I'm using Crucial Ballistix PC8000), I'll be very happy.

Nice, do post up the results. I'm currently sitting at 3GHz, DDR800 (memclock at 500MHz with DDR2-1000 RAM on a BX2), but not quite Orthos stable. I've never OC'd before, so I'm slowly tweaking voltages. 3 pages of notes and climbing... :)

I'm also watching the power meter (a Kill-a-watt). 152 watts on the system during Orthos CPU right now. Idle is about 97 watts. Yow.

Mine seems to be Orthos CPU stable at 1.45 volts @ 3.00GHz, but fails Orthos CPU pretty quickly at 1.475 volts @ 3.1 GHz. I'm a newb, I'm not ready to push to 1.5 volts yet. I'm going to try to get blend stable at 3.0GHz. :)

[HamidFULL]

every increase in vcore of 0.05v should give you another 100MHz provided cooling is approriate

[cblguy]

Well, I was rolling along at 3GHz anyway (orthos CPU, but not orthos blend, stable), so I decided to try some video encoding (MPEG2 to DVD). Computer barfed a hairball and I had to pull the "back to defaults" trigger to stop the windoze reboot cycle. That was fun.

I'm currently running 2750MHz (306 FSB) on stock everything else (BX2 "out of the box" settings, with RAM at DDR2-800), no voltage changes at all. I know at 312 FSB at stock voltages she goes unstable. I'm running orthos blend right now, and it's OK so far. Cooling is a Thermalright Ultra-120 with a Yate Loon fan, with another fan on the back as exhaust and a third fan blowing across the video card and northbridge. These orange fans are surprisingly quiet.

[CedricFP]

Wow, if it's failing orthos at 1.475 @ 3 GHZ, chances are you won't get much higher before you hit that 1.6v threshold.

[dinos22]

Cedric it seems he's got a RAM problem there rather than CPU

make sure you test your RAM with dual SuperPI 32M runs and check all your timings and vdimm

[CedricFP]

I see, missed that. Lower the multi and test the ram for it's max FSB is what I'd do. Also, what ram are you using? If using D9 chips, there is an interesting thread in Xtreme Memory about them failing quite a lot at anything over 2.2v, so if you want to play it safe...

[cblguy]

I might should start my own thread in a bit, rather than clobber up this one. ;)

But I'm using Crucial Ballistix DDR2-1000 memory. I'm running orthos stable right now at 2781 MHz (309x9) at stock everything. If I go to 315, orthos crashes within a couple minutes. I've tried bumping various voltages, but my newbness is showing through. Heck, I'm even running default RAM voltage right now (1.84V). I've tried changing that to get 315 MHz stable (change to 2.0, or 2.2V), and neither had any effect. I've also changed the CPU voltage (to 1.375), the FSB, the MCH, etc... my note pages are covered with voltage attempts. But back it off to 309, and it hums right along. I'm running Orthos as I type, cpu temp at 39-40c. Memory clock is at 463.5 MHz. I'm wondering if I'm at the upper end of this RAM, and need to drop the setting back to DDR-667. At least I have it stable and, to me, pretty darn fast. ;) My "old" PC is a Dell 400SC, runs SuperPi 1M in 56 seconds... LOL. At this clock speed, I'm at about 18 seconds on this PC...

[AndyM]

I wouldnt try to run your memory that fast for now in search of a CPU OC. WHen I was ramping up though 3.0, 3.2, 3.4, up to 3.6, my memory was actually around the 700ish ddr2 speeds on my BX2. Takes one thing out of the picture when you are looking at something else. I like the 1066 strap (tried the 800, couldnt find any speeds there that my memory liked, never checked the 1333 strap, but that is sloppy timings unless you really want mhz). Keep the memory below what it is rated at for now at the rated voltage, then play with that once you get the cpu where you want it. Also, I didnt have to dink with the MCH and FSB volts for Orthos stable until going past 3.4...magic numbers for me past that were 1.6 and 1.3, good up to 3.7. 3.8 probably too, but havent tried much trying to get Orthos stable as I was running out of cooling at that time. Good luck

Wait, your ram is binned to run at 500mhz, it shouldn't be encountering problems at 4xx. It might be an FSB wall of sorts - try go higher than 315.. like try going to 330 and see what happens.

[slim142]

I just heard of a guy buying an E6600 and getting good results** with it, not all new batches are bad after all...

**Sorry I cant remember what speed and vcore he used but I know it was a good speed with low voltage.

I think I might try my next E6600 from newegg

I think it may have been my inexperience. I noticed this morning that my Vcore wasn't changing after a reboot. When I pulled power from the system, it started changing. I'm now running Orthos blend in the background, BIOS set to 1.425 cpu volts, Everest showing 1.38 cpu volts. Clock at 2950 (327x9), still at DDR800 setting (memory at 491MHz). Previously this would have crashed out in under 2 minutes, I'm 10 minutes in and climbing. Fingers crossed. I think I have some breathing room. :) Edit: currently blending at 3.1 GHz, memory clocked at 518 MHz.

I have a E6400 @ 3.2ghz 1.35-1.375vc should I sell and wait?

[OBR]

I had tested lot of new E6600´s and all of them are max at 3.3 ~ 3.5GHz, they are really bad overclockers. Last chance for good OC is Xeon 3060 or oldest E6700 or "B" E6600 ...

I kno its only a 2Mb cache version. but my 6400 is doing 3.8 quite comfortably 1.5v actual under apogee. Think i could probably do more if i do a vdroop mod

[Postal Dude]

i think the 6400's are a very good option. Most of them seem to clock just as good or better than the newer 6600's and the 2/4mb cache difference really doesnt affect much real world performance. And if your lucky to get an L rather than a Q. You can do really well for yourself

[jacky89]

I just bought the week 41A E4300 from Fry's. Piece of crap. There's a fsb wall in the cpu at around 360. Right now I'm needing 1.52volts on my Gigabyte DS3 v3.3 to run it at 9x360. I tried other multipliers down to 6x and it still no go above 360mhz bus.

These E4300 are really a piece of junk in regards to O/C. I have 8 fans in my system and even while I'm able to maintain the cpu to 41deg C (modified Thermaltake Big Typhoon w/ Hi Speed Scythe Fan) under double Prime, it just doesnt go above 360mhz fsb.

[MuttonFlanks]

Hmm, my chip seems to be pretty decent until 3.42GHz or so. Can't get Orthos to run stable for more than 20 min and the temps will touch 70 under load even with my Tuniq cooling it. Although it does run at under 30 degrees at stock speeds and I am Orthos 8 hours stable at 3.24GHz at all stock voltages.

Yeah but I meant with newer weeks. The week 28's were fine oc'ers. The week 42's, however... a different story.

I suggest people buy from newegg.com
They tend to go through inventory a bit faster than other places.
Hopefully you'll get a newer batch.

Hi,

What about the Xeon 3060 ?

Are they suffering also of poor overclockability ?

As their price go down they come really attractive.

Anybody knows if their will be an E6420 in the Xeon family ?

I was waiting until the price drops too for an E6600, but did not place my order before newegg ran out of stock. Should I wait for more 6600's to come in stock? Or should i just buy one from a company that does have these left i stock? Would I get a better overclock from a 6700 at this point? I really don;t want to spend $300 extra for an E6700.

How longdoes it usually take for newegg to get new stock of e6600's? Is it going to be mroe than 2 weeks?

Anyone else get a week 45? I got a L645G333 and it blows. I can't seem to get above 3.150ghz but then it might be the ds3. I'm waiting on the dfi 965 now because I returned the ds3. Anyone have any experience with this chip? Or should I just ebay it. I'm looking for a chip that does 3.6ghz around 1.4-1.5v. Any week recommendations?

[CedricFP]

You may be just at an FSB wall. See if you can put the FSB higher by about 30 mhz. Increase voltage accordingly and see if it'll boot.

[hillwilla]

I ordered a Xeon 3070 it'll be here friday so we'll find out.

edit: as a side note I had to use 1.55000 volts to get 3.3Ghz with my week 42A.

Not feeling real good about this L640A that just arrived from the Egg today.:( They assured me before I ordered it " Our stock is always the latest because of our high turnover" Pack date 2-12-07 Blah!!!
