The Official X2 Overclocking Discussion Thread

[eclypse]

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?

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????

[±Pink=FloYd±]

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.

[fullup3]

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.

[drunkcarlos]

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).

[OverClocker_gr]

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.

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.

[alfaunits]

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;-)

[Brutus013]

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?

[DEVIL K-ce]

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

Poland box processor

Anyone have cpu on this series ?

[alfaunits]

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

[Lt_JWS]

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

[fullup3]

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

[aznboinghia]

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+

[aznboinghia]

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).

[alfaunits]

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 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

[alfaunits]

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

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

[SoF]

^^ 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
