2850 mhz with the win xp version gave me 777. About 28 secs.

Your render is 25 secs, and is that with the standard xp cinebench. What speed was your chip at?

3,1ghz as you can see in the capture ;)

I tried too the 64bit version :D

I used Windows 2003 server 64bit.

Currently available in Australia we have:

LDBHE 0603
LDBHE 0609
LDBFE 0610

Waiting to get a few more before I dive in though. :/

EDIT: How can you tell the difference between E4 and E6 by the stepping information?

I see all this talk of "vapour chill" cpu cooler , could some1 explain this ?
I heard a rumor that it is pipe-based with a low boiling-point liquid inside...
is this correct?

Hi and welcome seanx,

Yes, this is phase-change cooling, just like proper aircon. Asetek are currently the only manufacturers of phase cooling kit for PCs afaik, their site is:

http://www.vapochill.com/

Enjoy. :)

maybe he means their micro cooler

http://www.burnoutpc.com/modules/wfs...?articleid=213

I guess he could mean either lol

Does anybody know if the 3800+ CBBLE 0513CPDW overclocks very good? I now have a 3800+ that does 2700 mhz @ 1.67 under WC so I am looking for a better one.

Penny for your thoughts :banana:

Yes I did mean the "micro" version ty lawrywild ,
but I hear they r not that good , probably best for the price is
thermaltake big typhoon ..!

I am curious about a few things in my bios
hammer Fid control and hammer Vid control ? wot r these about ?

A few pics should be attached , got clock to 2530Mhz using 11x230htt
at almost stock volts 1.312 , the highest cpu temp is 59*C
cpu id is
ADA4200AA58V
LDBHE
D601SPMW

and the stepping (?) is BH-E4

I have noticed a couple of x2 3800 s' have this same id ?
I'll need a better powersupply (getting this soon) and hopefully better
cooling (don't know when) Tt big typhoon etc...
then maybe can do better O'clocks , ambient temps r high in zimbabwe
africa , around 25-35*C

FID is the multiplier, yours is stock 11 (i.e. 11x200 = 2200mhz)
VID is the vcore, yours is stock 1.35v but I wouldn't recommend you up that until your get better cooling because 59'C is extremely hot already.

hi,

got a X2 3800+ quite cheap. now i know why, it´s a toledo, stepping 0543 tmpw.

any experiences what results i could expect when overclocking?

thanks!

ty dude :-) ,

well the 59'C was during a cpu intensive test sp2004 (on both cores)
just finished playing a whole lot of games(5hrs) the last being BF2
and temp only 41'C . (which is standard)
btw my stock vcore is only 1.31

http://valid.x86-secret.com/show_oc?id=86691


This is temporary ,need to tune my vapor/phase cooling better :brick:

But for now i am running it om 3.1ghz daily :)

seems stable at 236 x 11 = 2596 @ 1.312v (in bios it is 1.35v)
ram @2.65volts and 166mhz timings 2.5,3,3,7 =185mhz ,I think cpu-z under reads voltage a bit.

since then tried pushing largefft (sp2004) and the 1st core failed immediately?
am I supposed to run it same as the small fft cpu test ? i.e
set 2 instances of sp2004 one to each core , select large FFT 's and start?
I heard that with prime95, in order to test memory , 2 separate folders r
required .....? does this hold true for sp2004 large FFT , or is there some
other glitch?

btw been reading from page1 , and currently upto page27 lol ;-).

p.s is Tt big typhoon better than zalman9500 ?

btw why is it that some ppl with 4200+ / 4400+ use the 10 x multiplier ?
since the default is 11x , surely the lower ur htt and the higher ur multiplier
the better ?
p.s I am very new to this x2 O'clockin , so pls excuse the ignorance ....:)

Lower HTT is not necessarily better. You can "tune" HTT to RAM using lower multis. For instance, with my 4600+, I'm running 250 x 12 and my RAM is happy at 250 1:1. But, if I could clock my RAM up to, say, 275 (it does 270), I could set 273 x 11 for the same CPU speed and get the benefit of higher memory bandwidth. Theoretically, I'd be better off with 300 x 10 and the RAM on a 180 divider for 270, but in fact it puts the RAM at 272 which is more than it can handle.

It pays to fool around with lower multis sometimes.

thanks stonecoldJimi , however I don't understand about ram divider ?
I have heard a lot of ppl say they r using divider ... but haven't managed
to glean anything from it.

I know that if htt = 230 , then ram = 230mhz (mostly ) how does this apply to
the ram divider ?

I got my new X2 3800 last wednesday, just wondering if this steppings is any good.


LDBFE 0612UPAW

Baron, that's the newest stepping I've seen. Post results as you get 'em please.

@ seanx

RAM divider is exactly that. Commonly you can do 5/6 x HTT, 2/3 x HTT, 1/2 x HTT. Look in the BIOS for this.

I got it from Lowestonweb.

Its at 2.2 at the mo ive only increased the FSB to 220 mhz, ill go for more later.

Ful specs if ya want em.

X2 3800 @ 2.2
DFI LanParty UT NF4 SLI-D
OCZ 2GB PC3200 Dual Channel Platinum Series EL-DDR CAS2 (CL 2-3-2-5)
PowerColor ATI Radeon X1800 XT 512MB ( couldnt be bothered waiting for the 7900GTs to get in stock)
Arctic Cooling Freezer 64 Pro
Antec P180

note: im a poor high school student, so if anybody wants to send me (FREE OBVISOLY) some kind of water cooling kit or phase change cooling kit feel free to do so

Guys i've found a 4400x2 CCBWE 0601MPM (without W at the end).Does anyone have a stepping like this?I can't find any info about it.

update on my try at overclocking ;-) set multiplier to 10x250htt ,1.296v(cpu-z) ram@auto,(208mhz = 2.5/3/3/7)Infineon and now seems to be running sp2004 largeFFT just peachy :-) temps at 54'C stable I guess those that recommended 10x multi were very right in saying it could be more stable!
Will look for the HTT divider option....
p.s I am super impressed with the low (54*C) temps

just some pics

just some pics ,

btw how important is ram voltage when o'clocking ?
I normally run my ram(infineon) @2.65v ,
I pit some heatspreaders on , could I push them up a bit ? will it help
ram stability / overclocking ?

got a chip for a friend
ADA3800DAA5BV
LDBFE
0609WPBW

again need a good power supply then after a week of running in/gaming
will do a burn-in , then o'clock :-)

Any ideas why i cant hit more than 2.5ghz with the rig below? :(

I even tried to see what the CPU can do alone, and i was unstable at 2.8ghz, with 8/10 ram divided, well 1 core was unstable.

I have a BH-E4 Manchester if that helps

orderd 2 3800+ both to arrive today ive got one which is a LDBFE 0612UPAW from lowestnweb just like baron. Ill have a look at the stepping of the other chip today because im only keeping one. I wont have chance to Overclock with this either for a few days :(

How will a CCBWE 0604 UPMW x2 4800 clock? It feels like a winner, but I can't find any history of this stepping online.

It is a 3800+ some are good, some are not.

My 4800+ runs 2550 @ like 1.31v

Hi, Im kinda new to these forums, but been about searching them for answers for a while, hopefully someone can answer this one for me.

I currently got an AMD Athlon X2 3800+ @ 2.8ghz @ 1.5v, this is an 0601 CPU (dont ask me for the rest of the stepping as its got a water block on top of it) but when I first got it, I remember looking the full stepping up and seeing people hit 3ghz with this CPU.

Its plugged into a DFI expert AA0 mobo with 2gb G.Skill HZ PC4000 currently at 264mhz, set to 180 in the bios, if I set to 166 I get no post.

I can get this CPU to 2.9ghz @ 1.57v 1hr Prime stable but then fails every time, I thinks its a memory thing as the memory is some what of a BIEACHHH to configure.

Any help on this would be greatly appreciated.

Memtest is your friend, right? There are quite a few HZ configs over at dfi-street that may be useful, but they're quite variable like HZ itself. Mine limits to 270 no matter what; if you're near the limit of yours, memtest will show it up in one pass. Let's have an A64Tweaker or A64Info screenshot too.

Thanks for the quick reply, Ive tried loads and loads of different settings, just cant seem to get anything to work, even tried dropping the Memory divider to 166mhz, but I get no post at 166mhz, so I guess that needs again a new set of timmings to post at those speeds :confused: , but here you go for the screens:

Quite a lot of differences between yours and mine - I relaxed a lot of things which helped it to be more flexible.

thanks mate, i'll give your timmings a shot, by the way what is your tref set to in the bios cos 200mhz 15us is a nightmare if not impossible to work out.

how are the 0603 doing. x2 3800

Update on my progress. Well, I saw UPMW and got a little excited, but it's been quite lukewarm. Haven't really messed with it yet, probably on the coming weekend. Initial results are in my sig, more serious testing will come later. It's only managed SuperPi and 3DMark01/03/05 stable so far.

I am sorry I do not have the number off the IHS, but:

x2 3800+ @ 2.4Ghz (10x240*) at stock voltage, and stock cooling, anything higher and it BSOD's, but I know good and well that that is a heat issue, and once I get some better cooling on this little monkey I have a feeling it will reach a lot higher clock. I bought this CPU from Newegg in the second week of Oct '05.

*I did it this way as my OCZ PC4000XTC (2x1Gig - UCCC) memory just wont take anything above 250, but here is what is weird I am running it at 2.6v...if I crank up the voltage any more, Memtest starts puking up red lines of text...hmmm, fascinating (3,4,3,8,1T). Anyways, I discovered that 10x240 gives me a hefty boost in speed both CPU wise and memory wise, is stable, I am still error free in Memtest at 250+ Mhz but with a 2t CR, which wipes out all the gains of the 1T timing. Temps under load never go above 48c.

what bios are most of u guys (with the good clocking X2's) using for X2's??

702 for me.

Anyone got a :

LDBHE 0602XPCW

Any results in terms of freq / volts? I might grab one soon...

its at 2.4 at the mo, havent changed any volt or mutilpyer ive just added a mem divider.

ill t and get some screenshots on here, just that i aint got the interweb on my new PC, ill get em up here and some added bigger clocks ive finished my exams, so about 3 weeks time

forgot to post this in the thread, i have an LBDHE 0601 TPDW, does 2800Mhz around 1.45 volts actual, dual primeable. I really need to get a better o/c mobo, 3Ghz on air might be 24/7 able on this guy :). yay 3800+ x2's, but i can definitly "live" with "only" 2800Mhz 24/7

Im pretty angry on my X2 result, just 2600MHz on 1,5V , anyway to improve it? I think its crappy energy - my current stable Vcore setting gets from 1,488 to 1,556 , pretty bad IMO , thats why setting things like 1,5V in BIOS doesnt work for me, cuz under load it drops to 1,458 and so ... Im screwed ... Anyway to improve OC? somebody help .. its LDBHE 0506 DPMW :stick:
BTW Whats that T & N chip thing?

Anyone had a 4400 and a FX-60? I'm really not happy with my 4400, because it doesn't matter how much voltage I put into it. It just will not be stable above 2750. Im running 250x11 right now just so I can have the low voltage. I can't get 255x11 stable even with loose ram timings and a divider.

I could get this overclock on water and ditch my TEC. BUT, I don't wanna ditch my TEC.

I think I'm gonna get an FX-60 and sell my 4400. Do the FX-60s overclock any better than their counterparts?

Well got my ldbhe 0603 wpaw to 2.6 1.4 so im very happy, havent primed but has never crashed even while gaming and doing super pi.

I have a 4400 X2 and now a FX-60 and i cant get 3Gigs stable with it on the first core 0. :( I have to run 245x12 2940Mhz to get prime95 runing. Sucks! Even on great water cooling and temps lower then 40C on load.

Is anyone something knowing about an X2 3800 0618EPMW????

well I got my x2 3800+ 0601 UPAW @ 2.5 @ 1.36v
anyone know how much voltage I can throw at this sucker... for 24/7 use? I have H20 so I should be able pump quite a bit...but I want it to be safe.

1.6v or so. No one really knows the answer to this question...its just a matter of opinion for the most part.
I say find the spot where the cpu stops scaling with voltage, and then hover somewhere in there.
For example, My 3800+ needs 1.488v to be stable at 3000mhz, but for 3050, I need something like 1.62v. The extra 50 mhz isn't worth all the extra heat and volts that I have to use.

has anyone seen or have any info on LDBIE 0618 38000x2's?

4200+ CDBHE 0607TPMW

Still tweaking, but this has been my daily 24/7 clock. Cooling is VapoLS. It will do 3.1GHz without issue, but needs 1.55V. Core1 is much weaker than core0 (almost 200MHz delta).

http://www.xtremesystems.org/forums/...1&d=1148795520

Can someone tell me the "good" weeks for manchester core?
My 4200+ died yesterday and know im going for RMA..
If anyone can help it will be nice

damn your 4200 is nice. My old x2 4400 took 1.7v to get that much out of it on my vapo.

push that thing further man.

0601 :fact:

Well I've been lurking for a while. I just got a LDBHE 0601TPMW 3800x2 and I'm impressed. 2.85 ghz is prime 95 stable for several hours (don't remember how long) but I wonder if its my motherboard that's holding me back. What's the concensus about the MSI K8N Nforce4 SLI platinum boards?

Thanks for your opinion,

Mike

I also got a LDBHE 0601TPMW 3800x2. It did do prime at 3.0 with 1.408v for 3hrs before core 0 gave up. (I only have screen of 2+hrs) Different story with better cooling though, 3.30 for 3d 05, 3.35 for 3d03, and 3.34ghz for 3d06. I must say having a 'BH' chip after having other cpu's with cold bug issues was fabulous.

Is there any software to tell the stepping? (i.e. to tell the 0xxx ???? string without removing the fan and looking at the CPU itself;-)

I just got an X2 3800+ (Manchester), and have a question. On stock cooling on the CPU, along with two 120mm case fans, how much do you think would be a possible OC with reasonable temps? Do you think 2.4ghz on stock cooling is an achievable goal?

Sick my 4400+ CCBWE0608GPMW can't 2.7GHz with 1.525V stable :slapass:
But 2.6GHz easy with 1.45V. Temp's is 32C idle, and 42-45C full load.

Poland box processor :stick:

Anyone have cpu on this series ?


Sory 4 english ;)

My X2 4400 does 2.6 with 1.4v (both BIOS and CPU-z) on A8N32
I get much higher temperatures, since my ambient is 30*C, and am using the stock cooler.
It seems A8N32 won't provide stable current for higher overclocks - but I can tell when I switch the cooler for a good one next week.

Dual prime stable for now, but doing 60+*C :(

Got this 3800+X2 couple of days ago :D LDBFE 0619WPMW, will bench fine @ 2.8ghz just fails prime in a couple of minutes :(

http://img91.imageshack.us/img91/184...51am9wb.th.jpg

Brutus013.....2.4 should be very achievable on stock cooling.
what week and stepping is your chip?

hi every1 im currently running a 4400x2 on a a8n32-sli dex. i wonder if will it be ok if i leave my cpu on 1.6V since when enablin overvoltage i can't get it blow 1.6 now matter how low i put my cpu voltage at. will it cause any harm? ill post updates on temp and clock rate once done =] please lemem nmow thx

I have same CPU and MB, mine will only do 1.56v max no matter what is set in bios. Some protection feature, I installed 3700+ and Vcore went to 1.6+

o tat weird mind let me do up to 1.62V on my 4400.. but is it ok.. to run tat high of a voltage on a x2? x.x

my chip not tat bad did 2.76 on stock voltage stable .. it can do 2.9 but wont be stable no matter how low i set my ram at -_-

Here are some of my subzero experiences with X2 3800+ Manchesters:

It is hard to keep them under subzero with phase under full load. My MachI@r507 shows -50°C display but processor still goes over zero (+5°C) with both cores on full load near 3GHZ and 1.55V. Seems the heat can't be transported fast enough or whatever, tried it without and with HS (and severval pastes all the same results) - almost no difference :(
It's quite fun to let them idle and make suicideshots: http://valid.x86-secret.com/show_oc?id=102539
But benching over 3.1GHZ is way easier with a single core processor. Had CDBHE0531TPEW - was a good old 05 model with 2880MHZ stable and Pi1m ~3100MHZ. Don't exactly know if it was coldbugged as my ballistixx only run exactly 250MHZ with it (stable and instant pi errors @251MHZ ^^) Bootet at any HTT.
Just got a LDBHE0604VPMW yesterday but strangly it does almost the same stable as the processor before - 2890MHZ stable with 1.55V and ~2920MHZ with 1.65V. But temps are rising with both cores on load @1.65V. It could do ~3GHZ @1.65V with -15°C but I can't hold this temp with a singlestage :(
Seems to be coldbugged as while reboots during first overclocks it wouldn't even boot with 1.55V @220HTT. Is the same problem I had with my Opteron...so boot @211HTT and Clockgen in autostart. 2890MHZ for now, will try to go a bit higher after week-end burn-in. But again no real 3GHZ :( I'm a bit sick of searching processors so I will keep it for a while if it makes no trouble. More tests of this processors maybe soon (suicide run of the '06).

Is the HTT holding you maybe? (multi 3 instead of 4? Or whatever it's called on GA mobos..)

BTW, I'm cruous... why do ppl invest in Vapochill or something that costs more than buying a few processors ahead and getting the same results?:-)

don't ask for it, I had enough processors to know my board settings @327HTT stable ;) It is the processor and "heat".

Well you can have fun with every processor you buy and do not have to buy so many of the same category...and not everybody can do ~2900MHZ stable with every X2 they get - that's the reason :cool: I don't wanna break the WR at the moment and don'thave the money for more processors at a time, so phase is still the best solution to get high-midfield oc EVERYTIME

I meant HT (the one that should be near 1000)

^^ when I tell you I know my settings for 327 HTT stable this surely includes a ht multi of 3....(and I checked them down to 2)...remember that you're on XS this is hardly something one of us is not aware of ;)

I didn't notice the number of your posts, LOL
I did see some ppl here who aren't XSers, solly ;-)

Has anyone else had trouble with one core of an x2 4400 failing Prime95 while the other core passes? Also, when I run both cores with Prime95 (each using 750 Mb, I have 2 Gb total), core 0 fails within seconds, core 1 is stable. If I test core 0 alone (defaults), it runs for a couple of hours before failing.

The details on my system and BIOS settings are here: http://www.xtremesystems.org/forums/...=80491&page=66

Thanks in advance for any help.

The situation you're discribing here http://www.xtremesystems.org/forums/...postcount=1644 makes it look like it's an heat related problem. One core can't handle the heat both cores generate. Better cooling will probably let you OC further. You max OC depends on the max OC of the weakest core, that's the case with all dualcores.:fact: If your temps get near 50°C stability will decrease very much. Also take a look at this thread http://www.xtremesystems.org/forums/...d.php?t=105295

Thanks, ChkDsk.

That possibility did occur to me, though I had thought it would take more than 50 degrees to cause significant instability. I am somewhat disappointed in the performance of my Zalman, I thought I could get better CPU temps with it. I am sure I installed it right, with a BB-sized dollop of Arctic Silver, fan blowing toward the back, and my case has a 120 mm intake and 2 120 mm exhaust fans, and a mesh panel on the side right over the Zalman.

I have had my eye on an Asetek WaterChill colling kit, I am waiting for it to come into stock, I may have to defer further attempts at OC'ing until I get this installed.

Thanks for the input,

Mark

Maybe it's not your Zalman to blame, but the IHS contact with the core. A lot AMD cpu's suffer (only if you overclock ofcourse, at stock their (or should be) all stable) from bad contact and removing the IHS often makes a big difference. But you can't do very much about it, unless you're willing to remove it (it Ã:banana:s Xtreme systems ofcourse).

I ran a lot of AMD cpu's without IHS, but the question is are you willing to take the risk :)

Anyhow, it probably is heat :p: Get some water ;)

hey guys. can i get some solid instructions on how to oc my am2 x2 5000+ ?
thanx in advance.

The instructions would be the same as any X2 processor such as 4400+ etc all you have to do is read the many previous posts or use google.com don't be lazy.

Thanks

ok i'll try not to b too lazy. thanx.

I don't think I am willing to remove my IHS just yet. I did, however, get an Asetek WaterChill cooling system installed...

I have gotten my oc stable at 2.607 GHz (237 x 11) with my memory on a 166 divider, 1T, timings on auto, but I need 1.52 volts to make it work. While torture testing both cores, temps max out at 44 degrees, a full 9 degrees cooler than my Zalman with an oc of 2.45 GHz at 1.42 v.

My next order of business is going to be to remove the memory divider (other members with similar setups to mine say that my memory can easily do 260 mhz with slightly loosened timings), and tweak with the timings.

My main question at this point is this...as long as my CPU temp stays under 50 degrees, can I increase the vcore some more? What is the practical ceiling for this chip?

Thanks for all your help!

Mark

I am currently at a point where I can go no faster and keep my system stable. I am now at 2750 MHz and do not seem to have a heat problem (I have liquid cooling and the temps stay low). Can someone please tak a look at my settings? Any good suggestions would be welcomed.

appreciate yout help

My Bios Settings

@cc3d, I think this mobo (A8N32) is a f***ing bad overclocker:(
I only found one guy in the A8N32 thread that had some impressive OC with it, all the rest is just for the kids :(

some PC makers like Voodo PC, etc are OCing AMD FX-60 chips (and others) up by 30% with this mobo. I am just now searching the boards for success stories. I sure hope you're wrong.

thanks though

Well, I've been reading XS for months regarding this motherboard, and only found ONE person who OCed over the "typical" 20%.
Can't get full specs from him though ;-)
Either that, or we're all running Prime95 which fails first ^^

2750 on a 4800... less than 15% increase over stock. exactly what i got stable on air, figured if i couldn't get at least 18-20% it just wasn't worth messing with.

no i'm not stalkin ya alfa

Yes, I agree, especially due to extra temps.

Hi, every1.
Assembled the PC yestetrday. Have changed SanDiego3700@2.6 to Toledo 4400+ CCBWE 0608. What the Fu..-only I could say after changing perfect air-cooler Thermalright XP-90C to 745Big Water. Why have I spent money for "water"-to get 2.6GHz again. Second CPU for the last year and so poor with OC. Hate AMD. 250x10.5=2625 OCCT stable with 1.55v. Temperatures-up to 41 Celsius in closed case. Big Water works perfect; while CPU doesn't.
"Death screenshot"-only at 2.75.
I'm totally disappointed. It's time to change horses-from Athlons 2 Conroe.

Poland box processor :stick:

Anyone have cpu on this series ?


Sory 4 english ;)

just about the all abovesaid. i suppose, pal, You understand me. People, don't buy long-cached Toledos CCBWE 0608 :( .

I am looking at an eBay X2 3800+ that has the stepping ldbfe 0623wpcw.

I think this is a good stepping? Would it be worth paying £20-30 ($45ish) extra for this cpu over getting a random one?

What might I achieve with stock volts and good air cooling (Scythe Ninja probably)?
Thanks, a quick reply would be great s its finishing in an hour.

couple of guys at our local forum were happy plenty-getting 0617; 0618 X2 3800-both of them achieved 3GHz under water with slight voltage increasing (about 1.5-1.525)

Have a look at this and tell me what you think :rolleyes:
This is my actual 24/7 overclock that I've been running for over a month now, stable as F*** ! :banana:

My CPU reads:
"ADA3800DAA5BV
LDBHE 0601TPMW
T699859A61020
ASSEMBLED IN MALAYSIA"

Take a look here! :rolleyes:

Are the 4400+ 89W good on overclocking? I'm planning to replace my X2 3800+ with this one. TIA!

I just got one of those on Thursday. Currently running at 2.8GHz on stock voltage and stock cooling. I haven't had the time yet to see how far it will go. I reached 2.97GHz on stock voltage when the errors began.

My new X2 3800+ LC...0624FPMW Toledo Core does 2.9ghz at stock voltages and 3.0Ghz at 1.45v.

I think that he makes much more than this, but my mobo maximum HTT is 301 so...


Stay Well ;)

Wow, that's a high OC for a 4400+. What stepping did you get?

Just curious... but how are people finding Toldeo's instead of Manchesters for the 3800 X2?

All I see at Newegg are Manchesters.
