Athlon X2 5200+ 45nm AM3 may unlock to Phenom FX5200

Well there's an easy way to tell if it's a deneb without installing the CPU. The second two letters in the stepping code on the CPU's heat spreader will be AC. This is repeated after the first space. Mine is CACEC AC.

My old 5000+ that unlocked is CACVC AC.
 
Well, i've risked it, banged a pre-order in. If it doesn't work i'll just retun it for a refund.

I'm never usually very lucky with these things though, so i've not got my hopes up :o
 
Ok so update time from me...

I've been running into problems getting much above 3GHz :( I'm fairly sure its a memory problem but as far as I can see there is no way of changing the Command Rate to T2 its forcing it to be T1 on my motherboard with no option to change it in the Bios! I'm on the latest Bios and it seems I'm not the only one with the issue after a quick google search! It runs fine as T2 at stock speeds and on a 667MHz Dev but at 533MHz it decides it can do T1 at those speeds and gives me no control over it!!!

Not good!

Anyway so:

Just look at those Volts :)

Seems stable but yes need to run it longer to be sure, its completed 3D Mark 11 fine at this speed also.

Now for the problem:

FX5200_2.jpg


As you can see its T1 and if I increase the bus speed upto 270MHz I get BSOD's as soon as I get passed the windows logon screen... sometimes get to the desktop and then BSOD. I've tried lower HT & NB, more volts on CPU and even a little more on ram, setting ram to 400MHz dev which resulting in me having to reset the CMOS altogether...

I when searching on google I found someone say that setting them in single channel allowed them to run T2 but I tried this as you can see in the screen shot without success...

I can't really see a way around this without changing the motherboard or getting some higher speed memory... unless Asus fix it in a Bios upgrade... really annoying.

I do as it happens have a cheap and basic MSI 770-C45 so might give that a go as it would do all I need feature wise but loose the option of crossfire... but it would mean a reinstall / reactivation of windows 7 which would be a real pain... I guess I could install windows on another hard drive etc but all a pain and takes up a fair bit of time etc...

To Confirm... Full Specs are:

Asus M4A785TD-V Evo
Ram: 2x Corsair CM3X2G1600C9DHX (2GB Sticks)
CPU Cooler: Tuniq tower 120
Case: Antec 1200
GPU: HIS HD5770

I think that's all that's required :)

Any ideas?
 
I could never get my 5000+ stable at all with 1T memory. Haven't bothered trying with the 5200+ yet.

"Look at those volts"? I think I'll be posting on that later. Can't believe how low I'm getting it.
 
Have you looked at Windows Event viewer to see if it's generated any errors or warnings in connection with the BSoDs? That can be handy in finding out exactly what the problem is.

Edit: I definitely can't go below 1.2v vCore at 3.24 GHz.

Further Edit: And who's this Michael? Too far away from my username to be a typo so I'm assuming someone else.

Click to expand...

1.2v at 3.24GHz is very impressive!

If I could get mine up to 3.24GHz I would be tempted to play with volts :(

I'm Michael, sorry message above was for me, all sorted now :)

I will see what happens tomorrow but might look at changing my motherboard over if I get the time... oh the hassle lol
 
8 hour blend work in progress shot:

Have to say I'm surprised by the voltages and temps.

Edit: Speedfan's Temp1 is my overall CPU Temp. Individual core temps don't work when unlocked.

I have the 5000+ running at 12x300 at 1.34v but i could only get it working with tri-core, quad core wouldnt boot to windows even with a boost in NB and core voltage.

Had a few issues with ram though, my ram is 1066 but certain stages of the OC the Ram would be clocked lower than 1066 but would cause the system to freeze.

Cant complain, only paid £20 for the chip :)
 
My 5000+ was a pain to unlock and get stable. I lucked out practically going on a suicide run with voltages and found it worked. Kicked out far too much heat and I ended up removing my 5.25" bezels and fitting an extra vent and 120mm intake fan just to blow more air at it. I got it stable enough to Prime indefinitely but if I ever looked it Event Viewer it reminded me that the cache was knackered with one Machine Check warning (corrected hardware error) every minute it was run as a quad. On the other hand it never crashed once I'd got it stable. Must have been pulling in some serious juice though. I reckon I couldn't have done it if my motherboard hadn't been rated for 140w CPUs.

This 5200+ seems to be a breeze by comparison. Currently 21 hours into a Prime95 blend and the temps haven't got anywhere near 50°C with the case fans on low.
 
This is one of the great things about AMD CPUs. I mean they may not be super powerful like what Intel put out, but they provide these little 'unlocks' which mean for budget users you can grab a cheap CPU and turn it into a very capabale tri/quad core worth double or triple the price. :cool:
 
Slight setback last night. Had an IBT failure just before bed. Not a complete lock up. It sort of hung for a couple of seconds, carried on, then gave me failure message. CPU temperature had been peaking at 47 so I don't think that was the problem. Settings are the same as for the 24 hour prime95 blend posted earlier.

Will come back to it tonight and see if more vCore or CPU-NB voltage helps.

Should have got on to running IBT earlier I guess.

Not a lot. It's a C3 deneb rather than C2 so same differences as the Phenom revisions.

This seems to generate much less heat and require less voltage than my 5000+ (mine looked like it was locked for a reason). The multiplier is 11.5 rather than 11. I think I got lucky and just got a much healthier chip this time round.

Nicely done getting 3.6 GHz out of your 5000+ by the way. What have you set the CPU-NB to? The bus on my rig is limited to 300, being hit or miss about whether it'll post consistently above that so never saw how high the chip could go. Getting over 282 means I need to over-volt my RAM, which is why I'm sitting at this speed.
