SL6WU 3.0c changed??

[Frost_Bite]

Does anyone know if Intel has made any changes to the awesome SL6WU 3.0c? I recieved mine in the mail today, and the caps aren't arranged the same as the ones previously posted. There's also a cap that seems to be outta place, way down in the corner. Has anyone else recieved any of the chips like this?

Thanks

[charlie]

yhpm, Frost_Bite

[a5h]

seems like some costa rica'n ones don't have all the caps. also some of the newer one's don't.

i received my SL6WU today too ...but i asked the shop for details and chose the oldest packdated one they had ;)

[Frost_Bite]

Will not having all the caps affect the SL6WU's performance at all? I'm not real familiar with actual chip design, but I would guess so.

Thanks

What is the date?

Well let us know how that goes then...all of the amazing results from those chips that I have seen most were of pack dates mostly from this year, in Jan...

[Frost_Bite]

My pack date was 1/16/04, so it should be a good chip. I'm gonna tear down one of my systems this weekend and install this new chip. I'll let you guys know how it goes.

[a5h]

packdate was Jan. 9th 2004 ...priming atm at 3.825 on my prommie @ default volts. shud hit 4g+ by tonight.

Thanks all the caps show similarities to the m0 stepping (EE's) ...which are kab00m OC'ers, so it shud OC more. since most of the 3.0c's that i've seen without all caps are limited sometimes to only 3.3Gs.

[Soulburner]

I've never seen a 3.0 crap out at only 3.3....???

[st0nedpenguin]

There was an article about this on xbit recently, something about the newer chips moving to an 8 layer instead of 6 layer substrate or somesuch, I tried to find it, but the search just keeps crashing, I hate IE4 so much it's unbelievable...:(

[enzoR]

luck is important...

[Frost_Bite]

Is there anyway I can send my CPU back and ask for another one? I bought it from ExcaliberPC, I'm about to tell them its DOA and get them to send me another chip.

[enzoR]

i dont think thats a good idea. here (in the netherlands) if you tell them its DOA the shops here will test it and if it works they will charge you 50 euros. not sure how it woks there. just ask them to trade it for anotherone.

[skate2snow]

I think those w/ some full caps are called something like EPA. The M0 are garantee to have those, so thats probably why they OC better. So probably those chips w/ EPA are some failed EE too.......

Yeah, I sent them an e-mail yesterday, and they're gonna send me another one. Its hard to tell which type is which, most people are getting the full caps, but very few of us are getting shafted with only 12.

[skate2snow]

Have you at least test it?

[daos]

yeah lets see some benchies!

[pkrew]

I picked one up today at the computer show. It was a malay. Pack date 12/27/03. It doesn't have the same cap arrangment as the 2.8mo that I have and has one that's seems out of place. I was bummed, but put it in anyway. I have it running at 260 1/1 so I'm not unhappy. Funny thing is that I primmed for 45 min w/o error, but it still give random reboots. I have it at 1.675 in the bios and on the Asus. I'll try it in the AI7 and see if it does any better.

if it's priming for only 45mins i wouldn't call that stable....so the reboots shouldn't surprise you too much

[pkrew]

Actually, it'll prime for several hours and its only when I stop primming that it reboots. I stoped it intentionally at 45 min that time. In fact it never fails prime it just reboots at idle, which is a little different, but it is a problem so I turned it down to 257.

[s81o]

Hi I have one of these new 3.0c's which I brought about a month ago after my local store got a fresh batch in. mine also has a few of the caps missing. iirc its a costa rica....Its doing 3.55ghz with 1.7v on a p4c800d with the stock air cooler atm.

im thinking it's a voltage problem then...but i dunno

[pkrew]

It could be, I have a lot of fans so I'm going to try using two psu's. I'm also going to try a 92mm tornado and see if the extra cooling helps. Honesly, I shouldn't be unhappy. Nothing wrong with 3.85G.

[mista_chewey]

yea that is pretty nice...my gay butt 2.8C M0 only got 3.36

[pkrew]

Well, I do have a spare 2.8 non-M0 than has been stable at over 3.6

[mista_chewey]

tempting but i just ordered a 3.0C from excaliberpc...hopefully it'll be the new stepping;)

[Frost_Bite]

I have a regular non-M0 2.8c that does 3.71GHz on 1.65v. My M0 2.8c does 3.81GHz on 1.65v. I try to keep my vcore under 1.65v, I'm always weary of running anything higher.

[mista_chewey]

hey frostbite i PM you...did you get the message?

[pkrew]

Great, I hope it works out for you. Those are nice 2.8's you have there Frost_Bite. I have a 2.8M0 that's like you're second one. It doesn't seem to like anything over 1.65v. I wish I had some nice bh-5 that would take full advantage of it.

[freecableguy]

I emailed excaliberpc...they don't have any SL6WU 3.0C's in stock...

[pkrew]

Screeming rig there freecableguy. How do you like the EE

Yeah, I just got the PM.

I'm glad I'm not alone PKrew, most guys are like "it'll take more volts, get it higher" I can run more than 1.65v on the chip, but it loses some performance. I just leave it at its sweetspot.

[mista_chewey]

yea i called them noon today monday
...but i didn't feel like canceling the order cuz i had hopes that they might have packed me the last SL6WU...what can i say im a dreamer:D

Mines the same way. You just have do work with what the cpu gives you and I've seen several 2.8M0 posts that report having trouble at higher vcores.

Mista, even if you get one of the non-M0 styles it still may overclock very well. Like I said it seems that the older style 3.0s are doing better.

[mista_chewey]

oh ok so i shouldn't worry too much that if i order a 3.0 and it's not SL6WU?

[Karnivore]

I picked up my 3.0C SL6WK oem from a Fry's it runs 4ghz @ 1.475 volts, and 4.5 ghz @ 1.7 under a mach1 it has the same cap config as the MO... might want to check there if you have one local, ask them to bring the box out so you can hand pick... thats what i did. cost is about the same as newegg, and you can return a poor clocker if you have to...



Moral of the story: doesn't have to be a SL6WU

[mista_chewey]

i know of a frys near by but i thought that their prices are over priced so i never shopped there are you sure they are the same as neweggs?
and what is their return policy? i think i might end up sending back the one i order from excaliberpc unopened don't want to becharged 15% restocking and probly not get a chance to return it

[Karnivore]

Well my 3.0C was 225 plus tax new egg is currently $217 dollard for it... so ya, i paid a bit of a premium, it was a little more, plus tax... But I got to hand pick my processor from a box of 30+, and I had 15 days to test my processor, if after the 15 days i wasn't happy i could exchange or refund.... luckily this chip was a keeper on the first try, but theoretically i could keep trying till i was happy..... IMO that is worth the slight premium...

[mista_chewey]

HELL YEA!!! i didn't know that they were that lenient i'll go do that as soon as i can return the one i got from excalibur

HEY THANKS FOR THE INFO!!:toast:

[Frost_Bite]

ExcaliberPC won't take the CPU back, un-opened or not. They do not return CPUs. Unless its DOA, you're SOL with returning it to them.

[mista_chewey]

damn...in that case gotta try to sell it...that f****** sucks

[pkrew]

When I was looking for a 2.8mo I ordered one from Outpost.com which is Fry's online store. The one I got wasn't an M0 so I sent it back for a full refund. They told me that I had 30 days in which I could return the product. The other thing is if you order online you don't have to pay the tax. Hard to beat that return policy

[Frost_Bite]

Here's a little update on mine.

3.9GHz @ 1.65v

Prime95 Stable for 12HRS

BTW: This is with my crappy PSU and 12v rail dropping to 11.75v under load. I think it will do 4GHz once I get the new PSU.

True, but for me I just hate waiting even a day for something, typically when i want something i want it now, and in that case even Over night shipping is to slow... 15 days, and tax is no big deal for the convenience, aleast not to me...

[mista_chewey]

very nice frost_bite you making me jealous and mad at the same time:D what kind of cooling and PSU do you have?

[pkrew]

I agree and if I had a Fry's within driving distance like I did when I lived in LA I would gladly pay the tax to have it right now and be able to hand pick what I wanted.

[Karnivore]

Here is mine, will do over 4 ghz @ default volts.

[mista_chewey]

once again jealous and mad....

[Frost_Bite]

I have a custom H20 setup that cools the CPU and GPU. Right now I have a crappy 500W Achieve PSU, but I've ordered a new PC Power and Cooling 510W PSU that should be here tomorrow or Wednesday.

[pkrew]

Ah, don't fret yet, you may have that 4G overclock on air in the mail as we speak.

I absolutely LOVE the P4 EE. What a kick-ass product it turned out to be. Well worth the premium. I like to indulge...what can I say. Anyway, I picked up a new 3.0C retail from Newegg. Might be a SL6WU, might be a SL6WF...who knows. I thought it would be fun to play with though...

[mista_chewey]

hey would having a pack date that is in feburary good? of 2004 of course...i called them and they said they got one in jan and one in feb...but i think people will not want to buy it since it's opened so thats why i didn't want to open it

I bet, I'd love to be able to afford a EE to play with. Good luck on your 3.0C

[MrCrusher]

Head on down to Fry's in Fountain Valley. It cost $234 but well worth it to be at 4G's the same day.
I just swapped out my 2.4c for a OEM 3.0c and now I am at 4G's on water. The specs are P4 3.0c\MALAY\SL6WK\L349A764. Its a D1 stepping and all the cap locations are full on the back.

[cold_ice]

I got my SL6WU a few days ago, it does 4250 with 1,78v bench stable. But whats a save Vcore for benching, as high as at the M0 CPUs?

[Marvin]

Just installed my 3.0C
L342B
SL6WU

I'm looking for my old thread, all the info i have is there, and saved no where else, lol, but i can tell you there is no pack date cuz its an oem...

ooh ok when did you buy it then?:D

This was my thread on it... http://www.xtremesystems.org/forums/showthread.php?s=&threadid=32035 The post was within a day or two of purchase...

i got the cpu....
it's SL6WK check my numbers with a guy on [H] forums exact numbers
he didn't get such good oc so im not gonna open it and send it back...i know i'll have to pay for shipping and restocking but i rather do that and go to frys' than get stuck with a crap ocer

[Frost_Bite]

I hate to be the bearer of bad news Mista...you're gonna have to sell the CPU. Excaliber won't take it back. I went thru the same thing, and they denied me 2 times. Like I stated earlier, unless its DOA you're SOL.

[mista_chewey]

they approved my RMA
i requested the RMA and they sent me the RMA # via email and said that there will be a restocking fee of 15%, and i have to pay for shipping

So you basically wasted $45 to give a P4 an all expense's paid round trip to your house??
Should have just gone to Fry's to begin with.

i would...but i didn't know about frys and their return policy and i didn't know that i coulda hand picked!!!! im pissed off anyways no need to rub it in

Didn't have a reason since i did not return it. Be honest it didn't perform to your expectations.

[mista_chewey]

oh ok i'll just say "it didn't perform to my expectations" and return it and then go buy another one?

I just pick up a SL6WK L401Axxx 30 Caps underneath. Your's a little better than mine. Mine needed 1.7v in the bios to be prime stable at 250 1:1 2-2-2-5(1.62-1.65 in window). I'm burning mine in for a few more days and after the As5 settle in then I'll try pushing her again. I try 255 last night and got to boot into window but not so stable. Temp on air at load is 53C.

[BuLkHy]

its weird that i can get 3,7ghz out of 1.525vcore,,windows read 1.56-1.58v ...but once i set 250 fsb....it crashes if i use clockgen and restarts...using bios wun even get me near bios after restarting..... mine is with 30 caps as well.... sumthing limiting or uncompatible in my rig?....

i got a SL6WK from fry's running 3.77 at 1.58 volts priming for 2hr so far

hey karnivore my SL6WK went up to 3.9 with 260fsb and 1.675volts in bios but underload asus probe reported it's like 1.6 or 1.58...
so i thought it would be fine if i upped the volts somemore to get 4ghz out of it but it won't even let me POST with 1.775volts at 267fsb or at 266,265,264,263,262,261 is my mobo limiting me??? but if i go to 261 before 267 then it'll POST at 261 but won't stay stable...? im confused???? :confused: can you help me?

Should probably consider doing the Voltage droop mod for your board, it may be your processor topping out but you should eliminate all other possibilities before saying thats it... Drop your memory speed via dividers if you haven't already.

Also all you folks running 3.0C make sure your PSU is doing ok, because these procs get pretty power hungry 4ghz+..

[mista_chewey]

my divider is at 3/2
power is enermax 460watt and my 12v rail is at 11.916v compared to stock speed with 11.97v underload
but i dunno how to do droop mod so much fine soldering and small things is a bad combo with me
should i just go buy a board from fry's and test it?

HERE (http://www.xtremesystems.org/forums/showthread.php?postid=331229#post331229) are links to droop mod, I guess as long as it won't cost you anything but some time you could try a different (Abit) motherboard, IC7 series or AI7 I guess would be good choices. My IC7-G isn't bad....



My Voltage stays right where I have it set, Using a TC550, your voltage isn't ideal but not terrible either...

[mista_chewey]

yea i was thinking about getting either an Abit or MSI to see if its the chip or the board... i bought this board when it first came out like last year around this time...
you got links to a volt mod for the PSU??
i think i can manage that if it doesn't have soldering

Unfortunately there isn't anything specific on your supply that I found, however any of the Generic mods will probably work. The downside is it would pretty much require soldering.

On a more positive note, if voltage is an issue member Hell-Fire has been offering a FREE modding service to ALL XS members, so if you need anything like that done see THIS (http://www.xtremesystems.org/forums/showthread.php?s=&threadid=29498) thread.


Yeah MSI isn't bad, but it lacks nice Vcore select above 1.7

alright gonna get the Abit then, those have stable vcores right?

My Abit have always had stable Vcore, but if you had the droop mod done on your Asus, you;ll definately end up with a top notch board....

[mista_chewey]

i just want to make sure that i have a good chip first.
and if my board is bad i surely will give hell-fire a call, to give it the droop

[BuLkHy]

i droop modded my p4c800 ..

niceee...so it overvolts at idle a bit and when underload its still over just a bit...did you hit a FSB wall before you did the droop mod?

and karnivore....i have a question about my powersupply...it seems to be making a slight clicking or crackling noise when i have my cpu usage at 100% should i rma this to newegg?

Tough call, it could be just because its under heavy stress, if thats the case a replacement might do the same. On the other hand the only sound I expect to here from my PSU is the fan, anything else and I would consider it abnormal.

[mista_chewey]

yea i stopped the fan with my finger by putting pressure on the center part where it's flat and won't cut my finger off:D ...still made the noise
BTW wondering what country are you in??because where i am Houston, Texas, USA it's 3:30 am when you replied im up this late because no classes tomorrow

Not to far from ya

mista,

[mista_chewey]

haha i see

[$oul]

I also have a 3.0C SL6WU and it seems that i can't go over 270 FSB stable :(
my vcore is 1.7v set in bios, cpu-z says: 1.664 to 1.680 @ load.
i tried higher vcore but i only got to 272 fsb stable wich is a bit disappointing anybody knows what i can do ?

I have a SL6WU from MALAY Pack date: 10/29/03

I could do 3.6ghz @ 1.575v on air with it now its letting me a bit down with my prometeia installed :(

anybody has any tips to improve fsb?

i'm using 5:4 with my mushkins pc3500 lvl2 @ 3v
timings are 3 8 4 4 (wanna get stable fsb first)
vagp set at 1.65v
abit ic7 max3 motherboard with vtt mod

[pkrew]

Why not try and give it a few more volts.

[$oul]

what is max vcore for 24/7 use ?
i thought it is 1.75v ?

[pkrew]

I've heard different things. 1.75 on air, 1.85 on a prommie. I think you could easily go higher in your bios as the max3 tends to undervolt. I bet if you set it to 1.75 it would still read less than 1.7.

[$oul]

vcore is 1.825v now and only got to 276 fsb stable.

cpu-z shows ~1.85v idle and 1.77v at load (prime95)

undervolts ALLOT on load :(

also my psu is modded @ 3.55v 5.25v and 12.5v i think that's enough power.


edit: when i set higher fsb pc reboots itself because of low vcore on load :(
