if u check out the cpuz speed that i benched the superpi @ u will see that its 3.1+GHz and in my jsig ive slowed it down cos i have each core F@H similtaneously and dont want to drop any half WU's :banana:

Nice chip you got there PiNh3aD! Why dont you post your settings in the other X2 sticky.

http://www.xtremesystems.org/forums/...ad.php?t=73800

wasnt referring to your 4800. was referring to a stock speed 4800. Someone posted earlier that my 2600Mhz would be equal to the 4800 speeds and i was just clarifying.

ya pinhead that is sick fast.. what are you cooling it with, and is it naked?

i seriously doubt a 3800x2 at 2400mhz is clock for clock to a 4800x2 at 2400mhz let alone "way faster" at 2600mhz if anything you would need 2600mhz outa the 3800x2 to match the 4800x2 at its defualt speed. not trying to start a war here just making an observation as a ex-owner of a 3800x2 running 3000mhz ....

peace perc,

it might be faster perc, the added memory speed might make the diff against a stock 4800....the cache is maybe 100Mhz on synthetic tests...

Here's Mine... sorry i will be updating it throughout..

this is just the first of many testing sessions.. to begin after Oct 12th due to d2ol'ing like mad


http://www.xtremesystems.org/forums/...id=37475&stc=1


apologize if this isnt in the format..

i will work on getting dual 32m's going.. i couldnt find the "target" to change to A0 or A1... will work on it...

the 2600Mhz 3800+ would outperform the 4800+. Remember the tests done comparing the 3700 San Diego vs 3800 Venice, the Venice won in pretty much all benchies.

like my sig says "chilly1'dGT" and no its not naked, the wife wont let me after i killed a '57 cutting off the IHS, so ive only had the x2 about 3 days now.

first day and a 1/2 burnt in @ 55C on stock air then just stuck it under the chilly1/507 mach2GT.........i can almost squeeze 39k on 3D01SE and im waitin on 2x512 pc4000 mushkin redline :woot:

90% of people here agree that the 200Mhz clockspeed will be superior to the extra cache. Its like comparing the 4400 to the 4600, less cache, higher clockspeed, hence higher rating and performance. Im wide awake, how are you?

ur probs right d00d but i still dont get it........i av more cache......im clocked higher........tighter ram timings......and runnin 1:1 FSB/HTT :confused:

x2 3800 @ 2.6mhz with 512kb x 2 cache is better than x2 4800 @ default with 1mb x2 cache.
But if u oc ur x2 4800 surely it's better than that x2 3800 :P

The keypoint here is the extra 200mhz can beat x2 4800+ at 2.4ghz with 1mb x2 cache.

I'd have to agree with you pinhead, clock for clock, your faster. There's no way clock for clock even a 3800 will beat a core with twice the cache and clocked the same. I don't buy that half the cache is better junk. Benches are cool and everything, but real world is where it's at for me. In the real world, 2 cores at the same clock, the one with more cache is king. Also Budwise, where do you get that 90% agree with your statement?

now im with u d00d, so what ur saying is if i leave mine @ stock 2.4GHz with 1mb x2 cache and u clock urs to 2.6GHz with 512kb x2 cache then urs will be faster.......ok d00d got it loud and clear........only thing is im @3GHz for F@H x2 @ the mo and clock up to nearly 3.2GHz to run benchies :banana:

yeah.. mathematically x2 3800+ users need to oc their cpu to 3.4Ghz to beat ur 3.2ghz in benchies.. :D

My god where does some of this crap come from.... Ever wonder why the 4600 is the poorest selling chip in the X2 line, it's not just the price, it's because the 4400 has been spanking it since the release. Believe whatever you like but you can’t remove half the cache and then claim better performance. This argument has been going on forever, remember the Celeron 300A? It overclocked like a banshee and you could buy it for a fraction of the price of its Pentium brother, people were attempting to make the same argument then. Unfortunately that dog didn’t hunt then, and it still doesn’t! There’s nothing wrong with these 512 cache chips, they represent great value and people are pulling big OC’s from them, but let’s move past this less is best theory, it’s just not reality.

you just cant generalise how much difference cache makes. In some stuff, no difference at all. In others, massive difference.

The cache is really not that big a deal. All things being equal, some proggy's sure benefit from it. Does my daily useage? no. I'll take a couple extra hundred Mhz any day...but again if I get the same clocks with the bigger cache, performance will be better of course, but not by much and not enough to justify the price difference.

Anyhow, buy what you like, vote with your wallet!

the reason i think people buy the 4400x2 over the 4600x2 is the price. who wants to pay 700 bucks for a 4600x2 when they can buy the 4400x2 for a less money and in the long run the 4400x2 will oc past the stock 4600x2 specs plus you get a full 1mb of L2 per core its a win win situation. i never heard of the 4400x2 spanking the 4600x2 i dont think thats the reason the 4600x2 isnt selling as good. hell you want to put it that way then the 3800x2 is spanking ALL of the x2's and for a fraction of the price of the topline x2's.

yes, i was only comparing to a 4800 at default speeds... As for the 4400 spanking the 4600 at stock speeds, someone is mistaken. The big seller for the 4400 is the cache and the price. Not because it is faster than the 4600, but you can always overclock 200Mhz, but cannot make more cache. But ifyou put them up together at stock speeds, the 4600 wins.

What I do guys is when a core seems to be failing before the other is go into the task manager and change the affinity for several different services to try and equal out the load on the cores. It makes a big difference in stability for your weaker core.

Is there any way to make the affinity change permanent?

Not for each service. You would have to do that each time you boot or run it. Now with applications you can just make a shortcut and edit the target with a space then -A0 for core 0 or -A1 for core 1. Just like you would do for super pi or prime.

Will my 90c work for a 3800+ also where has everyone been getting theres from?
if 90c will work ima get oem version if now ima buy retails, where would be est bet for good steppings as of lately?

I can't help but LMAO whenever I look at post like these! :rolleyes: I have 3800 and 4200 sitting infront of me and the 4400 with IHS off is running under a single stage phase change at the moment.......clock for clock this Toledo can't even touch the cheapest 3800, it's running much hotter than either one of my Manchester, show me some fact to back up your statement '4400 has been spanking it since release' :stick: If you're refering to the Extra Heat, Overpriced, Overrated, Inferior mem controller then yea I couldn't agree more, the 4400 indeed win hands down in all those regards.

Until those people own both Toledo and Manchester to compare and see for themselves, otherwise 'hype' is all they really get out of those 4400 and 4800. After all the X2 cpu that I've been through(two 3800, 1 4200, and 1 4400), 3800 no doubt is by far the best bang for the buck dual core out there, with decent cooling you still can get atleast 400 Mhz out of it, under single stage phase change or WC most of these 3800 will do 2.8~2.9. As far as the 4600 goes....it's about 150 bucks more than the 4400 but if HIGHEST possible overclock is your goal, then 4600 IS the ticket. If you're tight on budget then 4200 is even cheaper than 4400. Plus, the memory controller on these Manchester are superior to the Toledo so getting the 4400 or 4800 is a lose lose situation, not many people realized the 1MB L2 cache is way overrated, that is all. :stick:

After 46pages of overclocking experience with the athlon 64 X2 what would u guys suggest for the highest OC achievement?

Athlon 64 X2 4600 seems to have the "high-quality" Manchester DIEs.
Is that what you are guys have found out and if thats true what can i expect from an 4600 X2 watercooled or aircooled?
3000MHz are my personal target.

Well has anyone compaired a 3800 to a 4400+ in the same setup with the same settings to comfirm that the 1024k cache is a waste over 512k?

I believe that would only be the way to tell.. If i could i'd go out today and grab a 3800+ and bench it at 2800Mhz and see.

Woohoo, just got my 4400+. Its a CCBWE 0532TPMW. Hopefully this is a good stepping. Going to start OCing it on stock for now until I get my new heatercore, then I'll see what this chip could do on water.

i totally agree with you on this. i own a 4400+ and i really regret paying the extra bucks for the extra 512KB cache. i should have bought a 3800+ x2 instead. Although i can oc mine to 2.8Ghz with a big typhoon, it's not 100% stable. The memory controller is definitely a culprit here. until amd fixes the memory controller on the toledo core, bet your money on the manchester core folks. i'm stuck with this 4400+ for now, but i intend to rma it when the time comes :). after several memory benches, i can conclude that the memory controller is not as good as the venice or the manchester. my cpu suffers the same problem as most 4400+ owners out there. the problem is that the controller on cpu1 or core 2 is weak or faulty or whatever the case. cpu0 or core 1 seems fine and can prime95 for hours at 2.8Ghz. core 2 fails within 30mins-1hr. i guess the puporse of core 2 is a backup to core 1. i tried running games on each core seperately and core 2 fails most of the time, while core 1 ran fine. i also tried game that can use both cores like ut 2k4 and it seems to run fine on both core. here's an interesting example, i ran colin mcrae 2k5(this game requires setting affinity to either core) with affinity set to cpu1 or core 2 and the game would crash after 1 race. i switched to cpu0 or core 1 and ran the race and afterward looped replay for hours. now i don't mean to bash amd here, but i think they intend the dual core to work as a single with the extra second core as a backup. how else can you explain having a weaker second memory controller. i'll stop now before i get in deep trouble here :). peace.

dng29 : i played Colin Mcrae for hours without any problems , no need to set affinity here

PS : X2 3800+ @ 2.65Ghz

are you sure, because if i don't set affinity to either cpu0 or cpu1, the game runs at supersonic speed and i can't control the car. i'm using winxp pro with sp1. the gpu is 7800gt with official 78 driver. so you don't have to change anything when you run your colin mcrae 2005? hrmm odd.

If you are having choppiness or speed problems, some folks report making sure this line is in your boot.ini can fix problems with x2 and some games and some benchmarks...

/fastdetect /NoExecute=OptIn /usepmtimer

i can vouch for UnG's advice.. it fixed my problems with farcry.

I use WinXP SP2 , i also no need to do what UnG said , but u should have a try.

I never change affinity for any applications or games , just only for benches :D

i use XP X64 and dont have to change Affinity for games at all, but ive heard that X64 manages dual core/CPU better.

i bought the 4600x2 cause i loved my 3800x2 so much. my 3800x2 was a manchester core so i figured get the 4600x2 its a manchester as well plus the 4600x2 right now is the highest clock for a manchester atm so i would think that these 4600s would have the cherry picked cores.. plus ive only seen a handfull of good ocs from the 4800x2 and to be honest they seem to put off alot of heat even more heat then the manchester (and i cant even imagine anything putting off more heat then my manchester core!) wich means my single phase would just have to work that much more to cool it... anyways just my 2 cents.



peace perc,

Well thx Perc :)
So how does your X2 4600 perform?

dont have it yet should be here tomarrow but the guy (major) who had it before me says its awsome! he got 3200mhz and i believe he was running 3180mhz 24/7 prime stable using a single stage phase wich is what ill be using as well so i should be able to run the same clocks...

peace perc,

Wow yeah that is something :)
I am looking forward to some results of your Manchester.

my new x2 3800+ has just arrived. After 2 hours getting my :banana::banana::banana::banana::banana: of a DFI working, i'm currently priming it 2.1ghz with 1.26v. Small FFT's, and has just passed Test 2. (!)

It's a CDBHE 0533 UPMW, hopefully better than my rubbishy old CDBHE 0527 TPMW that did 2.6ghz with 1.6v.

i just got my 4600x2 today. the chip is already a proven clocker so not much of a surprise there as to what it runs. right now im having a few mounting problems due to this mach1 unit and the 4600 being naked.... ill post some results soon as i can.


peace perc,

a proven clocker...unless your using a DFI, it takes all the fun out. If you're using DFI, then results are so variable you can still entertain yourself. What's it proven to clock to?

3180mhz prime stable and i beleive he said 3200mhz was the max he took it too using his vapo ls single stage. ive yet to oc the chip but im sure that will change here real soon. and yes DFI is used in both cases so maybe results will varry? i think they will be the same give or take a few....

Is it an E6 or E4?...I have a 0532 week and is an E4...for now doing 2,6Ghz prime stable at 1.502V under water...hope can reach 2,7Ghz or even more :stick:

it's an E4. Now priming 2.2ghz @ 1.26v. Seems to love low voltage.

For some reason a lot of ppl seem to add more Vcore everytime they raise HTT but I have found (as others have too) that these 3800 Manchester AND Toledo's love very low Vcore

My Tolebo 3800 X2 is running now @ 2.6Gig dual prime large FFT stable at only 1.376Vcore but needs 1.520 to bench @ 2.8Gig fully stable :)

anyone have some ideas?
can i go more?
voltage to much?

Try some stress programs SP2004 (dual) and U will see if it is stable or not...if it is stable try to lower the CPU voltage....For the ram I have no idea, cause don`t know what chips ar on them...

My old X2 needed 1.6v for 2.55ghz stable, which was a bit rubbish. Hopefully this will like low volts more though. It's suprisingly cold running too, 31c under dual prime @ 2.2ghz, with my WC. my old one was about 33-34c, so it's a lot cooler.

33-34°C... :slobber: With my water cooling I can reach 42°C at 2,6ghz dual prime...with HS on...in idel is about 27-29°C at 1,55V.... :rolleyes:

Lower your Vcore to 1.45v in bios which should give you actual ~ 1.38Vcore in windows, it 'should' be 100% stable if its a good chip

I am not 100% sure but I have an idea that the v4.3 XMS should scale well up to at least 260 ~ 270 HTT @ 1:1 :)

if i scale t 260 or 270 what vcore and ddr voltage should i use?
any other voltages has to be changed? pciex vtt etc?

PS: do i need some drivers for the CPU? i instaled windows but no drivers for it.Are the ones windows installed automaticaly good?
thanks

Try it @ 2.5 first with 1.45 Vcore in bios befaore you start trying for 280, walk before you run :)

Which motherboard are you using ??, if its an NF4 chipset you should download and install the 6.66 drivers from here

yes it's abit an8 ultra...
i'm right now at 2.5 with 1.45 vcore and 2.9 vddr
i have.6.67

OK now you see if it is even half stable, do a few 16M, then if possible 32M Super Pi runs

Can you give a list of ALL you hardware, just list it all in your sig :)

For the best advice regarding the Abit AN8 the best person to talk to IMHO is Dinoss22 who you will find @ i4memory and also some expert memory advice :)

2.2ghz prime stable for 12 hours with 1.26v
moving to 2.3ghz.

anyone can tell me what's the safest voltage i can go on my X2 3800 because i think mine is dead... :confused:

i ran 1.85v thru my old one, no troubles. I guess it depends on cooling.

btw

2.4ghz Prime Stable @ 1.26v
Moving to 2.5ghz....this chip feels special. How many other people can get and keep volts this low?

Been slowly tweaking my X2 3800 (CCBBWE 0528)

Right now i'm at 2.7Ghz with 1.584 vcore fully game and bench stable.

One of my cores is really terrible and constantly fails SP while the other will go on forever. I have started to burn it in and it seems to be getting better.

Hi there fellows,

I'm with X2 4400+, running (24/7) on a DFI DLI-DR @ 2500MHz@1.24v, stock cooling and without and thermal grease...I'm waiting for my Prommy to arrive...

Anyway, I would like to ask you guys which is the bios bios available for these cpu's right now?....

I know it's one of those silly questions, but I would like to have a couple of opinions because I've been away for the last 2 months and I'm out of context already...eheheh

BTW: my mems are GsKill PC4800LA...they run @ 2,5-3-3-5-1T@2,6v@290MHz...


Thankx for the support

704-2BTA is the best.

is the 702/704 (DFI LanParty nF4) a beta yet/now?

Thanks,

Yan

What makes it better than any of the others?

it seems to work very well with more types of RAM (allowed my bh-5 to fly where 623-3 didn't) and it's a bit stabler, and often seems to allow for better overclocks. That's what i've noticed, anyway.

510-2 gives me the best 3dmark performance, u guys might wanna try that against the 704BT version. Btw, I was able to repeat this several times with my sandy and my 4400.

anyone here able to get their X2 and 2X1GB Memory to run 1:1 above 250? Id love to know your secrets cuz i cant even get it to run 1:1 at 240 and this is with Crucial Ballistix. What a waste having to run this great memory at 216Mhz...

Hi,

i still can not find out the correlation between the stepping and overclockability of an X2 3800 Processor. :(

How can i figure out, how good or bad some X2 3800 is oc'able? Have I watch out for the stepping, the production date or is it the batch code? What decides?

I can get one of these X2 3800.

No 1: CDBHE 0535SPMW
No 2: CDBHE 0535RPAW

Which one should I take? Unfortunately I can not test them, before buying them. Both owners can not make any declaration about overclockability.

I am looking for a model, what will run stable at 2500 MHz speed at VCore of 1,40 Volts (better 1,35 VCore), because I will run it at air cooling (Sonic Tower with fan).

Could anyone give a advice, which of the both processors would be a better overcklocker? Or shoud I take none of both and look for an other stepping? But what a stepping? :confused:

Thanks for answers in advance.

check out the 2x1 gig oc database man, it's a sticky, myself, I can run 290-300 on the ram. that was using dfi ultra-d board and everything else in my sig. try setting everything to auto for the ram.

Hi, I have some problems with OC-ing my X2 3800+...I have reached 2,6Ghz at 1,536V withouth problems, but If I`d like to go further I noticed that my VCORE is not stable...after trying 2,7ghz at 1,56 and 1,6V I have noticed that my VCORE is jumping from 1,56 to 1,58V and from 1,6V to 1,63V withouth any reason. Anything below 1,55V is stable but at 1,56V it jumps like described...This makes my CPU unstable usually after 10 minutes of dual SP2004 the VCORE starts to jump and I get an error after a minute or two of this...Is it the PSU problem or sth else? I have got an venice 3000+ and a SD 3700+ both OCed to 2,7ghz and above but I haven`t got this kind of problems...This problems starts when I make my water cooling and attached to the 12V 3x80mm fans, 1x92mm fan and 2x120mm fans...

Regards,
Primoz

p.s. First I thought it was my MOBO but after sent on RMA 2-times (2 different services) I have received the answer that was all OK and it OCs normally...

Here you go,

http://img365.imageshack.us/img365/2...stix5wf.th.jpg

and a tweaker screenie, I've tighten some settings, will update post as soon as I get home,

http://img250.imageshack.us/img250/2583/mem2kf.th.jpg

Pity my 4800 dont like the 9 multi, would have pushed the mem a little further.

my x2 is currently primng 2650mhz 1.31v.

Very very nice chip i've got here. Thought it was starting to crap out, as it wasn't passing Prime Large FFT's, turned out my RAM is not as stable as i thought.

hrm, well i ran Prime95 Blend test overnight and it passed with ram at 3-4-4-10 1T at 2.9Vdimm 1:1 250X10 (Neo 2 overvolts to 2.9 when put at 2.85). Although considering these Ballistix stock volts are 2.8Vdimm at 250Mhz i backed it down this morning only to see it fail Prime Blend immediately at 2.8Vdimm wtf? I put it back up to 2.9Vdimm and it passes. Could the memory controller be causing this kind of problem or is it the ram? Should i consider an RMA to Crucial cuz it seems a bit fishy to have to overvolt the ram to get it to run in spec?

u better try it in a diff board before you rma budwise, 99% of the sticks I have seen hit 280 easy.

the board monitor isn't nescarrily accurate, so frankly, if it works at 2.9v then thats fine. See how it overclocks before you get upset.

don whered u get urs from bro, u have an awesome chip dude..
Take her nice and slow and shes gonna give u 2.8 i beleive

I just ordered mine from monarch and Im going against the grains and getting el cheapo mobo asrock but I think this combo is gonna pwn :toast:
IU hopemy chip is something like urs..

Also what kind oif burn in have u done on it?
Put it in and burn for 24? or maybe 2.1 then burn\

I wanna try ur guide because either u have god chip or ur technique is good for that chip..

im in the UK, it was OEM from a shop called Lowestonweb.

My burn strategy was like thus. I really just fit it round my schedule tbh. I can't sleep with the noise it makes, and i'm not meant to have it on during the day when i'm not here. (might burn the house down apparently....) When i got the chip, i raised it up to 2.1ghz straight away, and dual primed for an hour. Stable, so i repeated this up to 2.5ghz, keeping volts the same. At 2.2ghz, i left it running prime for 12 hours as i had the time for it.
At 2.6ghz, it became unstable. I worked out i needed 1.31v to run so windows would be reasonably stable, although prime ran for 3 mins then errored. I then left it running cpu-burn for a couple of hours. Came back, and it was stable in prime. That is basically how i got it stable at requisite mhz, and i just did it again to get 2.7ghz stable. Ran cpu-burn for an hour, and bingo, stability is mine. Wouldn't run prime more than 3 mins, now is going on endlessly. Will keep going until i hit the big 3.0ghz, then i'll make it stable as possible. Preferably 24hr prime.

Hopefully that makes sense. If it doesn't, PM me or MSN me or something, and i'll make it clearer. I'd like to belive that my burn process helped the chip a bit, although tbh i guess i was lucky to begin with at getting such a fine chip.

Have U ran the the Burn-in in dual mode or single?...I`ve tried mine burning with SP2004 but for now I can get stable on endless SP2004 at 2,6ghz and 1,552V... :rolleyes:

Regards,
Primoz

dual mode obviously. Not much use doing it single.

Am I right in saying that if you have one core that is not as good as the other, if you just run tests on the weaker core then it will improve it over time?
Because I have one core that needs loads of volts once it goes over 2.6 and becomes a bit flakey, whilst the other goes up to 2.8 with no problems.

Just got my X2 to 3190mhz after tons of dram/cpu tweaking. Currently running at 1.5vcore (1.73 still doesn't let me hit 3200+).

Anyone know if burning my X2 in will give me a higher OC?

Thanks

Burning in my X2 only improved my max OC by 20 Mhz but I was able to run at a slightly lower clockspeed with less voltage.

i love this thread. Will setup my rig this weekend! X2 4400+ hmmm

Lol, my X2 3800+ (0529 SPMW batch 179) is prime stable @ 2500 mhz with stock voltage (1,35v). Not bad :cool: :rolleyes:

More results coming soon :p:

What seems to be the best bios for X2 cpu's?

704-2bt is working great for me.

623-2 is da bomb!! :)
2600Mhz @ only 1.26v (and testing my 3800+ with my vapochill within a few days :D)

704-2BTA works best for me.

I just stepped into the game as well currently dual priming at 2500 default voltages, dual stress primes :)
gonna go for about an hr then push for 2550 then 2.6
ima go till she wont let me anymore
As for this asrock mobo havin problems I havent had one yet
I went all way to 2450 with 1.3
had to bump to 1.35 prob coulda did 1.325 but skipped right over it and want to see how high I can go at stock..
unfortunately I cant raise vcore anyway so 1.35 is my max until new bis comes out, so looks like im in good shape as is..
als dual priming with hsf on at 38c which isnt bad, I think when I decide to go topless its gonna own, and lapp the HS :woot:

I have reached 2.6ghz Dual prime stable at 1.552V but can`t get any further...it seems to be the mem controller weak...cause I changed the ram divider to 166 and get no errors at 2.65ghz at 1.6V...before get an error after 2-3 minutes...Will try sth else...but can`t get to work at 2.7ghz stable even at 1.64V... :slapass:

To all that running at stock volts...do U use a divider for ram or what? Cause I checked my ram in memtest and it is stable at 265mhz @ 3,4V...but have problems to run Super_PI or Prime... :confused: I managed to do Super_Pi 32MB @ 2,7ghz with ram divider 183 but when tried out Prime95 it stops... :rolleyes:

well here it is, seems my best dual prime stable speed with 1.35 is only 2510 so far :(

sucks bawlz now I wish ida got me a ultra d instead

Theres still time to RMA which I might do, i got 2 weeks from today :slapass:


Oh and this is all 1:1 2t :(

I would be very happy if can get with my X2 3800 at 2510 with 1.35V

ive been burnin her in past 2 hrs at 2.4 with 1.3v :)
I know I have a good chip, its that I have a mobo that wont allow for higher vcore to be thrown at the cpu, and I dont have enough confidence yet to do the vcore mod, im thinkin about it though

I have a x2 3800+, I think I have a problem with Norton Antivirus 2005, it appears to be using >50% cpu which means it is multithreaded????

Or is it just stealing my cpu's execution units doing nothing?
I remember norton was never using >50% cpu.

This is when I updated it through liveupdate.....

cant help ya there bro I had a free thing for nortons so i installed it and it gave me problems so i went back to mcaffee 2005 internet security suite. she uses low %age

Looks like my comp is dead at home...have leftet it burning-in at same speed as usual and now I have no response...when I press reset or power button everything is dead... :shocked: hope will fix it when come home from work. Keep your fingers crossed for me guys... :rolleyes:

What happened? Is it just frozen or is it off and wont turn on?
