0550 UPMW vs VPMW

[003]

Yeah, well I also have the older rev of the Ultra-D, but that probably dosn't mean much.

[nealh]

yeap !! i have the same ideas also but here from what i see the vpmw the worst that they can do is 2800 either with aircooling!!

i have seen a lot of upmw that they don't go more than 2650-2700 also with vcore 1,55++

but as you said!! upmw,vpmw are very close!!

but I am seen at others forums the 170 vpmw not doing as well as 165vpmw(also the 165 either does great or "craps" out around 2700)

it does appear IMHO the a good 0550 vpmw is probably a little better than good upmw(at least for a 165)

But w/ air cooling I still think overall the 170 upmw does better..alot the 3Ghz(vpmw) are being done on NON air cooling..there are 2-3 I have seen at 3Ghz or close on air

Problem is (and I am guilty of this I see a few great chips around and they are posted at alot forums) and I "assume" I should get this as well..in my hands for whatever reason I always do less well than alot of people..poor tweaking of ram??, living in FL who knows

Look at my sig..I have a "ok" 0546 xpmw@2.7 1.5v..so what did I do..I am getting a 170 UPMW..I hope to get a 434L..even if I get so lucky..I will probably still never get a dream chip

I just sold a 165@2.6..0534 mpmw...I am waiting to see how the new owner does....he will probably get 2700+ ..LOL

My 0550 VPMW is at 2750 so far, still trying for more, but core 0 pukes out at 2800. Core 1 has primed at 2850 easily

I realize it's wintertime and everybody is doing their "extreme open window OCs" but when i see something out of place (like chipset loading at 23c, joe), i realize that ambient temps are chilled quite a bit, so you may as well tell everyone what the ambients are.

Chipset and gpu is watercooled (Watertemp. +15C) and an 120mm fan blows over the mainboard. (Roomtemp. +21C)

Thank you, gives us a better idea of what's going on.

Very damn good results too.

[THunDA]

I am getting a 170 UPMW..

Good luck.. !!

Im also getting one of those in the next week sometime ..

Ι got last week a scarce opteron 165 0551.
Full stepping CCBWE 0551 WPMW

Dual Primes 2730 1.52 on decent custom wc which is mediocre.Can do 2800 stable with 1.6 havent checked prime up there yet(still cold-hot ambient till spring hits)

Although i d like to test it on phase.Other marks is needs errata ON (possible cache controller sux) and the following screen which might make u wanna reconsider if your are on air.i havent tried it on air cooling and would think really to :P.

still not sure what that means with regards to -9 on temps....

Thunda..you are getting one from Dave too..here's to Good Luck on the OCs for the upcoming 170 UPMW from Dave

[K.I.T.T.]

CCB1E 0550 VPMW 2808 MHz, 1.42v, water

[Mr.President]

^^ yep, it seems tho..you crazy germans have taken all vpmw's
i hardly found 1 in-stock and order it right away

yep we the germans bought ALL vpms

Usually low tCase max is regarded a bad clocker o bad memory controller.

but all the opterons I have seen say 49C .....am I wrong, have others seen higher temps

[no_n|ck]

heh, well not all..i have been able to snack two more
so now i'm getting; 502xx, 504xx, 505xx batches
should be here on monday, and yes all where bought from ''carzy'' germans

[nealh]

OK..I am going to say uncle and once again missed the better stepping

it now looks as more reports are here and elsewhere the
170 0550 VPMW is better for having a chance at 2.9-3.0ghz at a low vcore even on air

looks like 50XX substrate are best???

Of course I was able to get my hands on a 170 0550 upmw 434L substrate..I hope it deos better than my 0546 xpmw or at least as well on lower vcore....

[berk]

170 0550 upmw 434L

Mines coming next week sometime from Dave @ Flickerdown,hope it clocks well with my TT BT
I'll post the results anyhoo's.

An update from my 0550VPMW



If you don´t plan to go subzero i´d say 0550VPMW is the best choice

[FireDragon]

my opti 175 does 2750 with 1.35 in bios...but with a load on both cores i am pushing well into the 50's with a nado and si-97 that i modded a while back when i first got my winnie becasue they sent me the wrong kit...any way i have had this chip over 3gh taking it out side in the cold...i am going to go water cooling soon and that should DRASTICLY help...maybe a 3ghz chip on water with 1.55

I am getting the same 0550 UPMW Opteron 170 434L and was wondering how this CPU compared to others you have tried?

Also, what overclock you have accomplished on air - what vcore, temps etc..

Let me know.

Trying to decide whether to keep 0550 UPMW (unopened) or 0550 VPMW I have on order. If I knew the VPMW was going to be better for sure I wouldn't even bother opening and trying the UPMW 434L.

i'd say, wait for VPMW - even if you will not be able to achive 3ghz, it will run 2.8/2.9ghz with much less volts than upmw .. i had 3 upmw's (all 434L), the best one was doing 2.85ghz with 1.55V .. now i have 3 vpmw's and one is doing 3gz@1.48V, and 2 of them are doing 2.9ghz with 1.4V .. btw, you can still open the box in the way it can't been seen it was opend (be careful with the sticker) ..

[Grinch]

170 0550 VPMW dual prime stable at 2.9G on air with vcore 1.4V (1.42V in bios)

what type of HSF/FAN are you using to get there?

[Grinch]

0550 VPMW opteron 170 here

my 0550 UPMW is a 165, and I am having problems with the mem controller on it above 310, so still messing with that.

BOTH ARE EXCELLENT CHIPS!!


My 0550 VPMW Has a very weak core0, or a strong core1 depending on how you look at it.

burning in core0 hasnt gained me anything, but still trying

2.8gighz - stock vcore
2.9gighz - 1.4 vcore
3.0gighz - 1.532 vcore

havent tested any further. I can boot into windows at 3.2gighz, core1 is fine. Core0 just is killing me though.

if that is air...with those speeds I imagine that they are what you can boot into windows with?

[Absolute_0]

VPMW gets the vote now
I can do 2.90 Ghz dual prime with stock 1.31v

Today arrived my 0550VPMW

This is a first test, i have to rebuild my wc and see what is capable (tried 3ghz at 1,52v but temps were too high).

what cooling?

[003]

I see alot of post all over on these chips...I wonder if there is an easy way to collate the data...

it seems for many the :

0550 UPMW is best available(obviously 0530 are great too but not really around much) 170>165???

0550 VPMW look very good or just ok??? 165>170???

0551..too few around


Do I have it all wrong

I would like to see more posts in KITT's thread

http://www.xtremesystems.org/forums/...ad.php?t=86531

From what I can tell, VPMW is better for 165 and UPMW is better for 170. 0551 seem to be very hit or miss

Good pretested CPU's often sell for more than brand new ones
