anymore ideas? can't check mine..who can post another 3000 Venice pins pic? :stick:

Tom
ill try and find some pics on the web.
Looking at some tech docs, the CADIN pins that appear to be connected belong to the hypertransport link i think.
I found some other interesting pins though.
http://www.xtremesystems.org/forums/...id=35897&stc=1
What could those be for? Not normally used? Then when are they used? Hector, tell me.. what are they for?!?! :slapass:
These might also be interesting. I'd compare an FX with a locked cpu and try to find differences in resistance between the pins. (not that i have an FX or the time to do it right now though)
http://www.xtremesystems.org/forums/...id=35898&stc=1
yeah, why hasn't someone compared pin resistances of an fx to a locked A64? Oh right: time. Gotcha. Well, someone needs to do that. Seriously.

Don't know how true it is about the Ts only on FX grade.I have SD 4000 with T

Wow, I just finished reading this whole thread, and all I can say was I was on the edge of my seat the whole time. It may be worth getting a 939 system and a 3000 venice, taking up smoking, following his exact way of living for 2 weeks, then get unlocked multi's. Nah, my sempron system has an 8x multiplier, so we need to change that. It may be time to check out all of those pins.
Are there others willing to shell out say $10 apiece for a community project to get to the bottom of A64 unlocking?

Why would you find any more information comparing his venice to other venices than you would comparing a san diego to a FX?
I got $10 on my paypal so count me in ;)
Have the cpu registers been compared to a locked 3000+ yet? I've only seen Pir's dump come by in this thread.
I would deff give $10.00!
Well, because no body posted some pics, here are some pics of a locked Venice 3000+ which are original posted by mklaassen:

very very interesting...
unlocked venice that used to be locked...
magic man, that reminds me a P3 550mhz I once checked and it was unlocked... ahhh old times.
AMD datasheets refer to CPU's "Model-Specific Registers" that store the useable multis, default voltages, id bits...
Page 324 in "BIOS and Kernel Developer's Guide for AMD Athlon™ 64 and AMD Opteron™ Processors":
MaxFID value is stored in a register called "FIDVID_STATUS":Code:Address Register Name Description
0410h MC4_CTL page 207
0411h MC4_STATUS page 207
0412h MC4_ADDR page 207
C001_001Fh NB_CFG page 365
C001_0041h FIDVID_CTL page 374
C001_0042h FIDVID_STATUS page 376
C001_0048h MCi_CTL_MASK page 207
If we could reprogram this "FIDVID_STATUS register" we could rewrite the "MaxFID" value to, for example 25...Quote:

Huh?
Edit:
Id for FID 9x seems to be 00_1010b, 25x is 10_1010b. Only the first bit is different...
Conclusion:
AMD techs must've overclocked their PROM machine - and occasionally it puts a wrong bit in the wrong place. Pirs' proc was programmed wrong...
:D

Wow.... :eek:
so maybe we could "trick" or reprogram the "FIDVID_STATUS register" using possibly a modded BIOS or maybe a home-made proggie??
If so.. Who is good at programming in assembily? :p:
Anyways really looking forward to seeing some experiments over the next few weeks.

Pirs proc shows 11_1010 as its max multiplier.
All the bits in that register are read only, so I really don't know how do you intend to write those registers. The only way I can think of is on system power up (maybe), when you just turn it on, maybe you can access that MSR and change it's value.

11_1010 is not included in this table... What if this "unpredictable behavior" includes all multipliers becoming enabled?Code:Encodings not listed are reserved. Using reserved encodings will cause
unpredictable behavior.
It won't most likely.Quote:

You can calculate the multi using this formula:
(Multi Code / 2) + 4 = Multiplier.
(Multiplier - 4) * 2 = Multi Code.
