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'll give this a try. thanks.

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?

Interesting.. never read that before. I dont have probs but will have to try that out anyways.

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:

Regards,
Primoz

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 :)

Interesting but unfortunately I found out that my X2 3800 like at least 1,5V for runing it at 2,5ghz stable... :stick:
