Phenom II 960T...anyone had luck with a 6 Core Unlock?

MOOGLEYS said:
Have you tried giving it more power ? Unlock the cores and give it a bit more V-core and see what happens. You are safe up to around 1.55v.

Are you using the stock cooler ? and what M/board are you using ?

No stuck with standard voltage, motherboard is a asus m5a78l-m usb3 and cooler is a scythe samurai, this is because its in a silverstone htpc so needed a low profile cooler, ram is 8gb kingston 1333 hyper blue, and graphics card msi 560ti twin frozr.

With regards the voltage, I assume this is the cpu overvolts setting in bios, any idea what I should start at ?

oh and forgot to add the windows event log warnings when running as a hex core seem to be the only problem as it will happily complete 10 runs of prime95 or intel burn test

ok overvolted to 1.35 and its stable with 4 cores at 3.5ghz now, not tried with hex cores again, but may tomorrow, however an overclocked quad is probably more useful to me than slower clocked hex.
 
I've unlocked mine on a M4A79XTD EVO, perhaps you are just unlucky and the two disabled cores are damaged too much. I previously had a PhenomII 555 and that wouldn't unlock to even a tri core, luck of the draw really...

Well I tried MOOGLEYS settings from above, thanks by the way and unfortunately I failed the stability test, I got into windows but the moment I started to stress it I got a BSOD...

Anyway I had previously only been trying via multipier with a 200 bus speed, I had found 3400 at 1.35v my limit for hex core, with a manual setting of 2400 for NB and HT speed, to be honest for £95 I was happy with that, I'm just trying to squeeze some more life out of my M4A79XTD EVO.

After the failure at 4000 with 1.45v and 250 bus speed I dropped the multiplier to 15 from 16 and so far the stability test is looking good, so I'm up to 3750 hex core now, I think!

Settings I have are as follows;

Bus: 250mhz
Multi: 15x
VID: 1.45v
NB: 1.3v

Result: Hex core at 3750mhz

thanks MOOGLEYS,
J.

Rather than trying to squeeze it up to 4ghz, I'm going to try to slightly reduce the voltage on the CPU and NB at its current 3.75ghz as I'd like this to be a 24/7 clock...

ok have been having a play and wondered if someone can do some checking for me, whenever I enable 6 cores I get the following in event viewer every min.

Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: Cache Hierarchy Error
Processor ID: 2

This does not cause me any stability issues at all, the problem goes away when I set to 4 cores and over clock to 3.5ghz, but battlefield 3 seems to run much better with six cores enabled rather than an overclock, so would prefer to leave it at this.

could soemone who has unlocked check their event viewer for these warnings, I am guessing it may be due to windows not recognising the cpu part ?

I just find it a bit annoying as I generally like everything to be working perfectly and would ideally like it to stop.
 
Hi welshrat, I've just checked in my event viewer and I aren't seeing anything like that, I'm running Win7 x64. I've looked in them all but paid particular attention to Windows Logs - Application and System and Applications and Services Logs - Hardware Events and I haven't got any entries like that.

I'm currently unlocked to 6 core with an overclock although for the most part I'm running at 4x multi at 250mhz = 1Ghz as I have CnQ turned on...

Hope that helps, we could probably do with a few other unlockers commenting re their event viewer entries...

Ok thanks for this, I suspected it might just be me, can't find anyway to remedy this on the internet and am worried it may eventually cause instability, so may have to sell the 960t and maybe look at a proper 6 core or a bulldozer.

Run a few hours of prime and see if all is ok. Personally I would ignore the windows event viewer.

Ok thanks Moogleys, currently been running prime for 30 mins no errors yet, so hopefully will pass tests fine, if it does, its just a little annoying.

ok 2hours of prime ran, no errors, I know this isn't 100% conclusive, but as the event logs start as soon as windows starts, I think its reasonably safe, any many thanks to you both and at least I can run as a hex core until piledriver arrives.

Ok decided to give overclocking another go with the six cores enabled, set it at 3.3ghz, ran the intel burn test and then played battlefield all evening and then again in the morning, but then suddenly it blue screened, with stop code 124, set it back to 3ghz no probs since, I would normally be happy at that and assume I can't overclock, however.

I used to have a asus xonar d2x and msi 560ti however I have removed the xonar and replaced the 560ti with a zotac 448 560ti (much better card, 448 not the brand), but with the old setup it used to crash pretty much straight away when set to 3.3ghz whereas now it lasted a good 6 hours worth of gaming and browsing.

also when I set it to 3.5ghz the intel burn test failed but did not blue screen

so a couple of questions.

1. could it be my psu is not supplying enough juice when overclocked, its an akasa 550 watt 80% rated.

2. what is the standard voltage of a hex core as I have just left the bios at auto, but figure the bios may be not suppling the correct voltage as its an unlocked hex rather than native.
 
If it's running ok unlocked at 3ghz I would say the unlock has been a success and you have a clocking issue. Have you tried more Volts to the cpu ? Set the V-core to 1.45V and go for 3.2ghz and run burn test on high. If this passes gradually reduce the voltage until it fails. This will give you a base voltage to work with. Keep an eye on the temps whilst its burning..

ok thanks and fair enough, to be honest no real reason to go above 3ghz anyhow as performance seems fine in all I need it for, just fancied getting to 3.4ghz or something as auto seem to set the voltage at 1.35 and drop as low as 1.29
 
Auto is not the best when overclocking as you don't really know what it decides to set it as.
Tbh I would run it as a Quad and try and clock it as high as you can stable as for gaming this will give better results.
 
Ok me again :D I have had a good play with the bios and it seems that I can happily overclock the 6 cores to 3.4ghz using 1.38v however as its unlocked the core temp no longer works and the motherboard cpu temp measures 61 degrees max under prime ?

Is this a problem as when I have it operating as a 4core the core temp is always 10 - 15 degrees lower than the motherboard cpu temp however I cannot find a definitive answer on this, and every man and his dog seems to have an opinion on it which one is a correct guideline :-)

I am using a zz samurai in a htpc case and our living room is upstairs so it can get quite toasty up here, I currently get 59 degrees on prime at its current clock just wondered when its not safe, typically gaming even on BF3 it never goes above 54 degrees.

OK I'll have a go at this welshrat, I've an unlocked 960T too and the temperatures for the cores in AMD OverDrive and Hardware Monitor all read 0 too. As I understand it these are not accurate anyway but in HM TMPIN0 is reading from a temperature sensor in the cpu socket and TMPIN1 is reading a sensor on the motherboard, it is on mine anyway, I've verified this with ASUS PC Probe2 which also reads sensors directly, that is why they work instead of just reading 0 degrees. They both match so it must be right.

We could do with some Phenom 2 know it alls really, as I understood the Phenoms they have a max cpu temp of 62c and I think that is according to AMD, I'm in the same boat as you really as with my unlocked 960T i'm also reading 61c when running Prime95, it is stable though.

I'd say we are both probably on the edge of failing, but I wouldn't worry about it, in everyday use surely we are never going to max all 6 cores out like Prime95 does! Or am I just guilty of wishful thinking?

I'll monitor this thread to see if a guru guy or gal gives us some more definitive answers...

regards,
J.
 
Yes I am using PC Probe too, my thoughts are however that because the sensor is in the socket and not on the cpu that it isn't a direct representation of the actual cpu temp.

Glad to know you have similar temps though and like you say unlikely to hit these under normal use.
