Chance to unlock to a Quad for under £50

How did you get along?

Unfortunately It looks like I've not been so lucky this time :(

The CPU unlocks and POSTS fine as a Phenom FX5000 Quad Core, goes into windows fine but when I run prime for 10 - 15mins the PC just turns off without warning, tested as a dual and its fine, used my other OC settings and its seems to be running as a dual core @ 3.1GHz without problems, just running prime at the moment.

gamesaregood what volts did you use for the fsb?
mine craps out at 2.8ghz

1.35v, these CPUs do not need a lot of volts for overclocking at the speeds we are trying to do with this chip, post up some CPUz screenshots and I will see if I can spot whats causing the issue for you.

when you unlock the disabled cores, they run at slower frequencies than the normal cores.

This is of course all incorrect, and it is indeed not a safe guarantee when you unlock the disabled cores. The reason for this is that the disabled cores are turned off for a reason: they failed factory tests. Cores can fail for any number of reasons, including defects in the silicon, problems running at full frequency, or a bug introduced during manufacturing.

When you unlock the disabled cores, they will run at full processor frequency, since you cannot run each core at different speeds. While you may see initial gains and benefits from turning a dual-core CPU into a quad-core CPU, you may introduce instability into your system. Things may corrupt, calculate incorrectly or even crash.


just a copy and paste job (is it worth the risk)

This is rubbish, its true that some are failed CPUs and its quite possible that some might fail for pointless things like a watt or two above what they should be but on the other side some are perfect CPUs which are locked because of supply and demand.

Can you post the link if its within the rules?
 
No matter what volts i put through and HT link i cannot push above 2.8ghz, but at 2.9ghz it can boot up but prime detected cpu failure on core#1, so i rebooted pumped volts upto 1.45v and prime says core#0 and core#1 failed :(
so anyway this is the best i can do...

(p.s) i like how core temp detected my cpu as a phenom x2 55000 :)

Are you running Torture test in Blend?

What speed is your memory & NB running at? Would be good to see a screen shot of that also :)

The Core Temp is an interesting one... I ran it on mine and it showed:

I then realized that yours is the version above so updated it and:

So deffo is a chance in their latest version :)

Here is a screen shot of it running as a quad also:

got a week 35 and an m4a785d-m pro mb. unlocked 3 cores with latest bios. 4 and it bsod's at windows logo. whats the ACC stuff about anyway?
core 0,1,3 works for what its worth.

I think one has to use extreme will power to avoid buying these lottery ticket processors otherwise you end up spending more money that what a new Intel® Core™ i5 chip costs . . .

If you get lucky then enjoy and count your blessings, if you are not so lucky and get a chip that won't unlock then tough heh! :p

@ gamesaregood: Stop buying these chips heh, you lucked out first time you jammy sod . . .move on while you have a few quid left, I don't wanna hear stories about you becoming homeless because of a processor buying addiction! :cool:
 
imc on these cpu is ****ed. runs mem in single chan, and if nb > 1600, unstable. there's really no point buying more than one, unless you can sell it for the same price, which is unlikely. 3 cores means ive saved about £20

Picked up one of these, a mobo and some RAM as an upgrade path for someone else's aging p4 system and got a CACVC AC 0936BPCW and it looks like I've not been so lucky... oh well, it'll still be a massive improvement over the p4!

I'm going to try a few more BIOSes before I give up all hope, as I came across a thread where someone with a 550 couldn't unlock his chip with certain versions of the BIOS for his board (including some newer).

Also - anyone here got any experience of unlocking on a DFI board?

Same here. Will unlock 0 1 2, but not 0 1 3. So core 3 is no go. Unless i need to do somthing else in the BIOS? I don't know much about Bios. Could someone direct me to somewhere i can see some screen shots or just tell me which settings need changing?

I've update the BIOS to latest. v 0603 on the m4a785d-m pro. I've change a few setting, but not sure on voltage etc. Any help please.
 
Had just ordered a Jetway HA08 Combo board (combined AM2 / AM3 with both DDR2 / DDR3) and was thinking about trying to unlock a Phenom II or Athlon II.

Spotted one of these 45nm X2s going for £36 delivered (offer now expired) and it seems like as good a chip as any to practice on. If it works - happy days. I've got it more as something to play with, rather than through any expectation of success.
 
Just had a quick go last night. Not working yet. ACC on auto but still posts as 5000+. There is quite an old BIOS installed on the board. It's dated March 09. Am I right in thinking that the ACC unlock trick didn't pop up until later?

Having read a few BIOS release notes, it looks like A07 seems to support unlocking. Not sure about later revisions.
 
Latest version might not be a good idea for some manufacturers. AMD 'fixed' it with later microcode updates. I've emailed Jetway to ask if the later versions on this board support it.
 
Tried BIOS A09 (most recent). It recognised it as a phenom FX5000 but wouldn't boot into Windows.

I've switched to the earlier BIOS A07 which I'd seen had confirmed unlocks of dual core phenoms and I am am now typing this booted up as Phenom FX5000 x4 @ 2.2GHz.

Seems like a reasonable start. I need to go and install some stuff @ default settings and then I can try playing with my new Quad :).

Edit: Will post more once I've got everything up and running. Meanwhile:
