..just moved this from wrong forum, sorry
Have any of you actually been able to increase your multiplier past 16??? This and the new 5000+ are supposed to have 'cusomisable multiplier' yet I sure can't move upwards on my DFI board on the latest bios, and it seems someone else can't on their cheapo board.
Can't seeem to find any evidence around the place
Cheers
when the 6400 was released, one of the disappointed newegg revs said the 6400 was downward unlockable only... so that at least confirms your finding, if you can trust a ne rev...
edit: found it..

Rating + 5Rating + 5Rating + 5Rating + 5Rating + 5 fast & stable
Pros: A fast 3.215 GHz, and stable at 100% load on both cores with a CPU temp of 41C (Antec900 case with a Zalman 9700 heatsink). Has a 1.424 VCore. DDR2 at 400MHz x 2 due to the even multiplier. Best bet if you need a new AM2 chip now and don't want to overclock. I've had the FX-62 at 3.215 GHz but it took a 1.6 VCore to get there, not too mention the heat...
Cons: The multiplier maxes at 16x (it's only unlocked with regards to lowering the multiplier: standard for the x2's). Would have been nice to get an unlocked multiplier since the 6400+ was released at a "premium" price compared to the other AM2 chips.
Other Thoughts: Antec 900; Asus M2N32-SLI Deluxe Wi-fi; Thermaltake ToughPower 850W; AMD 6400+ @ 3.215GHz; Zalman 9700 Heatsink Fan; 2 x PNY 7950GT in SLI (w/ 512MB GDDR3 each); 2 x Corsair Dominator 1 GB Dual Channel DDR2 800; 3 x Seagate 300 GB SATA HDD's...
The 6400 doesn't have an unlocked multiplier, that's why you can't move upwards. I should say it doesn't have a fully unlocked multiplier, as you can adjust downwards only. Only the 5000+ (Black edition) has the fully unlocked multiplier.

I don't understand why the 6400+ isn't upward unlocked to be honest, why did they evenbother mentioning it in the literature? everything with CnQ is downward unlocked!
oh well. Thanks all.
I'm disapointed, :(
5000+ Black Edition = 2x512kb and Energy Effective
EDIT: Im confused, is it a 65nm Windsor? (Never heard of it before though)
I find ton's of different info on it, what is 100% true and what is not?
just guessing, but I'd imagine it's a 89w 90nm windsor.
all the 5000's:

edit: nice... the site goes down as soon as I post a link... http://products.amd.com/en-us/DesktopCPUFilter.aspx
Its a Brisbane, if its 65nm.
I get et now :D
I tried both 6400+ and 5000+BlackEdition on DFI's NF590-SLI.Quote:

I couldn't see over x16 multiplier in case of 6400+,
but I confirmed that 5000+B.E. is unlocked upto x25 at least within DFI's NF590-SLI BIOS.

So, I think unlocked-6400+ is just a rumor...
...I've not tried CrystalCPUID's mulitiplier changing function, though.
is that the regular 6400 or the black edition:
http://www.engadget.com/2007/08/20/a...black-edition/
or is the 5000 black a 6400 with unlocked multi!
Regular 6400!?Quote:

And of course, my 6400+ described in previous post is Black Edition.
how's the overclking of 5000+BE ?Quote:

thx a lot
maybe they forgot to update bios with black edition microcode. so no upper multiplier selectable. is it?
Is there any difference in colbug from 90nm(f3) to 65nm? Heard rumors the new 5000+ B.E is a new revision of 65nm, could anyone confirm this?
6400+ is not unlocked!
kyosen what type of cooling did you use for 5000+ OC'ing?
Thanks for the replies, I think that's fair confirmation only the 5000+ is unlocked.. weird.
Tictac: I thought this too, but kyson can go upward on exact same board with
a 5000+
Kyson: Mine wont budge with Cbid.
LIXMARK: From what I and others have found.. absolutley, brisbane is much worse.
F3: operate @ 200 down -20c to -30c. 250htt clock+ @ ~ -10 (for me at least)
G1 brisbane: Operate @ stock down to 0 to -10 , clock vs temp, not 100% sure.
PS crap that is a nice Overclock for a brisabane, Kyson!.. 2 stepping looks interesting :p Also interested to know what cooling

Though CoreTemp 0.95.4 shows -1 deg-C, it's not correct...too low.
I got 3.5G with mild water-cooling...yeah mild water-cooling,
assisted by mild running air-conditioner wind...around 18 deg-C temperature.
CPU-Z shows Vcore=1.552V, and it's almost accurate.
great results Kyson :D
might wanne join Victor for the 1M wr :D
I spoke with Chris Tom over at AMDZONE.COM and he says his 6400+ is completely unlocked, both up and down.
so need bios upgrade to unlocked upper multi?
very interesting freeloader :)
Perhaps that's it tictac.. shame no bios update for a while from DFI :(
hmm strange, according to AMD 6400 isn't unlocked!Quote:

Subject: Athlon 6400 X2...

> I just read your review of the Athlon 6400+ X2. Good review. I was
wondering if you could tell me if that CPU has a completely unlocked
multiplier? Basically, can it go above it's 16x multiplier? Thanks for
any help.
That's the response I received from him.
I also read a month ago that the 6400+ was to have a fully unlocked multi.....most likely this will be bios related.
Agreed. :DQuote:

Still it is weird why one black box is unlocked(5000+) and the other isn't(6400+):confused:
Also ,now it is clear that 5000+ is "revised" G1.Latest OC reports back that up(kyosen).
Tom is definitely wrong:Quote:

Why would anyone use higther multi then 16 anyway?
Don't you want to overclock the memory?
Im on a 165 Opty and I got it running 9x322 for 2.9ghz and 241mhz on ram.
Bravo :yawn2:Quote:

ouch....so the 6400+ defo isn't unlocked.....that is a bummer. :down:Quote:

My 6400+BlackEdition is upward locked.
My 5000+BlackEdition is upward unlocked...upto x25.
16x is the highest on my 6400+ on biostar 560 am2+
Oh well, not that I would need that high anyway, gotta overclock my mems:D
Ah, I understand...yes, downward multiplier changing are available
for both 6400+B.E. & 5000+B.E., as usual, of course:)
I had thought that locked/unlocked argument is directed only upward, here XS:D
why would the bios make a difference as the 5000 is the newer of the two? Therefore it would seem to me if there was a problem the 5000 would have it too.
So it seems the final verdict is
6400+ BE: Downward unlocked ONLY, like any X2
5000+ BE: Downward AND upward unlocked like an FX
Thanks for all the responses :yepp:
so 5000+ BE for the win?!!!! i'm thinking about trashing my 5200+ and getting the 5000+ BE... as I'm stuck with my current setup..it won't go anymore

I just got my 6400 and I am up to 3500MHZ easy as we speak. Will look to do more soon.
I am at 250X14 and 500DDR2 with my new 8GB's of Gskill memory :p:
4X2GB
Asus Crosshair
Nice.
Mine is arriving early next week, I hope to get 3.5ghz.
mine is under a Mach II so hopefully eventually i'll be able to pull about 3700MHZ
