Finally found a good X2

**ben805** · 09-30-2005, 06:02 PM

So far I've went through two X2 3800, a 4200 and 4400, all of them are very poor overclockers and required load of vcore, decided to get the 4600 but my local computer store didn't have it in stock, though I saw two 4200 on the shelf, one of them has a stepping of CDBHE 0524 RPMW, the other one is CDBHE 0520 MPMW, well...be it the good ol' Barton, Winchester, Venice, San Diego, or these dual core, for whatever reason the earlier stepping always seems to clock slightly better so I took the later, without much effort here is what I got....

X2 4200 CDBHE 0520 MPMW:

This 4200 LOVES lower vcore, very good memory controller as well, I'll have to play around with it and see what else is left in it

**eBoy0** · 09-30-2005, 06:15 PM

Nice dude... 6th time is the charm or w/e

what i found is these chips hate voltage... my 4400 does 2.9 @ 1.52 under a chiller... but hits a wall at 3 gigz and no matter what voltage... might be mem. controller.

**ben805** · 09-30-2005, 06:29 PM

my CCBWE 0532 TPMW 4400+ with the IHS removed won't even prime at 2.90 regardless what vcore I'd tried, it has a very weak mem controller as well. My very first 4200+ stepping was CDBHE 0524 SPBW....only manged 3.04Ghz @1.68v with 256MB x2 GSKILL, if I use the XP4000 Redline or 2GB Ballistix then 3.0Ghz max, but memory controller started to failed, and it died few days later

hopefully this one would last me for the next 6 months

**eBoy0** · 09-30-2005, 06:31 PM

My first 4400x2 one core did 3.2 @ 1.66 while the other one crapped out on me way back at 2.9 1.7

i hope this one does better.

**ben805** · 09-30-2005, 07:21 PM

this 4200 is awesome....3.0Ghz @1.53v prime stable!! not sure if I can lower the vcore down another notch but I think this is definitely the sweetspot

1.53v....sweeet!!

looks like I'm going to keep this one and skip the 4600 for now

**nn_step** · 09-30-2005, 07:24 PM

nice core you have there...

This is how the x2's like the mess w/ people. Try to do 3.1 if you can do 3.1 then your chip is great. Mine like i said does 2.9 at like 1.52... but then hits a wall at 3 gigz.

**ben805** · 09-30-2005, 08:32 PM

I'd tried 3.13Ghz (11 x285) at 1.65v earlier and after 30min on two instances of prime the Smartguardian reports the cpu temperature fluctuated at 7~9'C underload, I have a UEI DT200 temperature probe on the evaporator next to the core and it reports somewhere around -22'C~-25'C, another probe on the compressor and it's kicking out about 75'C of heat....I have a portable A/C running in this computer room as well but this single stager is cranking out some serious hot air, I had already added a 120MM 110cfm exhause fan on this phase change but this tiny little Matshushi*ta compressor is taking a pretty good beating by the massive heatload

I might be able to lower the vcore back down to 1.63v @3.13Ghz but for now it's probably a good idea to take it easy on this 4200, still not sure how the previous one died so I hope I won't kill this one by pushing it too far...only wish I have a cascade to keep the heatload down.

**ben805** · 10-01-2005, 10:59 AM

Lower LDT and Chipset voltage seems to be fine too....yay!

**PCnerd** · 10-01-2005, 02:35 PM

Wow dude, thats sweet

**harobikes333** · 10-01-2005, 02:46 PM

good lord you haev money to burn

gemme some lol jk^^

**MaxxxRacer** · 10-01-2005, 03:59 PM

amazing chip you got there.

and yes you have boatloads of money to burn.

**ben805** · 10-01-2005, 05:39 PM

I dont' have butt load of money to burn

wanted to save some money and bought the lower end dual core, but before I knew it I was spending more and more money to try different stepping just to hit the prime stable @3Ghz mark, If I had to do it all over again I would definitely jump on the 4600 and be done with it. For my next upgrade I'll definitely get the higher end stuff instead of keep buying the budget stuff in hope to get lucky

**Major** · 10-01-2005, 06:30 PM

Nice results man !

**ben805** · 10-01-2005, 07:57 PM

Thanks Major

This 4200+ has an excellent memory controller as well, no problem running my 2GB of Ballistix at 300 @3-3-3-8.

The rest of my X2 can only do 290~292.

**Absolute_0** · 10-01-2005, 08:04 PM

Very cool. Are you going to try for higher clocks? Would it respond if you gave it 1.62 volts or not?

**ben805** · 10-01-2005, 08:38 PM

thanks

yes it would respond to higher voltage, but the tremendous heatload put loads of stress on this little compressor

11 x295

**IvanAndreevich** · 10-01-2005, 10:30 PM

This is just insane. How much do you think it would do on air?

**ben805** · 10-01-2005, 10:53 PM

I'm not sure....haven't try benching anything on air ever since I got the phase change, I think it should do 2.75~2.8Ghz on air and around 2.9Ghz on water?

**cupra** · 10-02-2005, 04:19 AM

very nice, same as my 4200, i jave a 0422tpmw
ander d.ice it pi 1m at 3.1g and go up to 3.42g not stable (311x11).

**i found nemo** · 10-02-2005, 05:22 AM

how come the big difference in pi like 10 seconds

Congrats on the scoop, fantastic CPU

,

But if you do wht you say in your comments, you would never have come across this chip

. Keep tht in mind on your next CPU buy, heeehehhehee

For some reason my core 0 is slightly weaker than core 1, it's always the first one to failed whenever I tried to prime at 3.0Ghz with only 1.46v. All my X2 have this kind of behavior as well...either core 0 or 1 is weaker than the other, from what I've seen on all the discussion threads I think this is normal.

thanks man, yea I know what you mean....it doesn't make the next purchase any easier, would always keep wondering 'what if I get another one to try...'

**Russ_64** · 12-15-2005, 11:48 AM

Hi guys - sorry for bringing an "old" thread back to life BUT

I just got my X2 4400+ OEM with:
ADA4400DAA6CD CCBWE 0541MPMW

From what you guys are saying above is this a good core/stepping ? I was expecting to get RPMW/SPMW ??

**saaya** · 12-15-2005, 12:22 PM

what a nice christmas gift ben

karma paying back

PArrrrAAAisah the ocing gods!

what is it i hear? more vcore? more mhz? they demand more vcore and mhz sarcificed to them!
