AMD "Thuban" Core (Phenom II X6) XS Overclocking Charts

I need your help guys. I've got a x6 1090t.
Aaand so far I've tested it with OCCT at large data sets test. After a bit of hussle I've got 4h + stable at 1.425 volts ( in bios) at 4.0ghz. In cpu-z it shows that at idle the volts are at 1.44, during load it's 1.456 -> 1.467. Question : ARE THOSE VOLTS SAFE fro Thuban 24/7 use ?
I've seen the AMD states 1.4v to be the max.
P.S. I very much do like those 4.0 ghz =)
my temps during load are : 55-56.

P.S. Maybe some day I'll do Linpack, but in my experience the occt was the best one. On pc's that I could pass 12h of Prime, and take IBT for 1-2 hours to make a nice fried egg I've faild OCCT in 1-3 hours.

Yes,i think even 1.5 is safe to use.

Hello,

I have been a reader for a few years but this is my first post so please be nice. :D

This my third AMD System after K6-2 and Barton and also I am also quite new to overclocking. It is my 24/7 system and has only been running for 3 days now, so I didn´t have time for a lot of tweaking after work, I will try to find out the max OC @ stock Vcore at the weekend. Anyway, I am quite pleased so far, especially with the combination of undervolting and a mild overclock while keeping turbo and CnQ enabled. Specs:

Attachment 106483

Here's my 2 cents :
CPU Model: AMD Phenom II X6 1090t
CPU Stepping:
CPU Frequency: 4.0ghz
CPU vCore: 1.430 set in Bios, 1.440 in cpu-z during idle, 1.456-1.467 during load
CPU Multiplier: 20x
CPU Turbo: Disabled
NB Speed: 2600 MHz
HT Ref Speed: 200 mhz
RAM Speed: DDR3-1600
RAM Timings: 8-8-8-24 2T ( didn't bother to configure tigher timings)
RAM Configuration: 4x2gb Patriot
RAM vDIMM: 1.85
Stable/Suicide/Untested: I guess you should put it in "Untested" since I did not test it for 8 hours +. But I concider it stable, just wanted to play starcraft 2 and couldn't wait 3 more hours lol
Motherboard: MSI NF980-G65
Chipset/Socket: AM3, N200
Cooling: Venomous X-rt
Temps: 32C Idle / 51 max Load, 49load after 3 hours ( thanks to air conditioner dropping the ambient room temp) ( Shows min 40 there, because I started CPUID after occt)
Tested 2 times. First - 4.5h of OCCT large data set. Second : 5h 13min of occt large data set.
+ a lot of hours in starcraft 2 and heaven benchmark and some vantage runs

Update : I've changed my fans surrounding CPU and my temps dropped by 6-9 degrees ( avg and max). Awsome :D

To overclock the 1090T is much better than 1055? To not gonna change my Phenom II X2 @ X4 by a X6.

Im currently trying to oc this chip but im struggling with my ram...

is my current progress. The ram is rated at 7-7-7-20/1600MHz @ 1.9V but im concerned that the voltage is too high because 1.9v in the bios is red and it scared me away :(
so far the highest iv'e dared to go is 1.71 but that wasn't enough either. Would 1.9v be too high for 24/7 use? (im new to the green team)

Bought myself a crosshair iv and the 1090t. Got some ram but I finally had one of those problems where it wasn't on the qvl and it wouldn't work so I can't run the system yet, but the new ram is on its way from newegg. Should be fun considering I have it on the vapo to play with.

Its been far too long since I had something to tweak.

1.9v is np at all if the RAM is rated for it, board and cpu can take it.

Charts updated. Guys, I'm not going to budge on the eight hour requirement. :) I need a screenshot of a solid 8+ hour run of some stress test to put you down as stable.

8Hrs of prime is not even close to what 3hrs of linx can do.

Perhaps not, but I'd have to see a scientific(ish) demonstration proving it. Until then, it's 8 hours of any standard and recognized stress test.

I wont spend this time at this time but, linx is for CPU, prime will test memory and IMC better.

50 pass of linx using all the memory availble is more than enough to check stability for our daily use.

@particle: Sorry, I misinterpreted your post #17 in this thread:

I'm not a stability nazi by any means. Use whatever method you'd normally use for determining stability. The more time the better though. The more accurate the submitted numbers are the more the chart will help us determine overclocking trends.

I'd recommend as much stress mode on y-cruncher as you can stand with a minimum of 2-3 hours.

---

So i thought that 2-3 hours of prime would be sufficient. I will make a run on the next weekend with 8+ hours. :)

Btw my above settings are also stable with 1,225 VCore. Pretty nice so far on the cheap board.

Ram rated at 1.9v (not 1.7-1.9) should be Micron D9JNL/GTS/GTX and should be safe up to 2.1v. :yepp:

Well so much for wanting to get a good clock in soon. My vapo seems to be dying. Normally at stock I would see it not ever go over -45c full load on the evap head, now I undervolt the cpu to 1.2v or less to even get it down that far. It gets up to -15C on load at stock, I only noticed it because when I installed the vapochill software it said -4.7C when I opened it and I went :eek:.

I may try remounting the head again, but it looks more like the compressor is about to die completely. I'll probably find someone who repairs refrigerators around here to look at it.

This is just not my week with technology...

Edit: Also hasn't worked yet with dual channel memory, doesn't work at all in the red slots. Its only worked in the black slot closest to the socket. (Motherboard is Crosshair IV).

The interpretation was correct, it's just an outdated post. If you read on, you'll see that it was suggested to me that without a formal definition of stability the results are as reliable to us and outsiders as a Jello battering ram. I revised what would be required, announced it in the thread (page 2-4, somewhere in there I think), and then revised the first post to clearly reflect what stable, unstable, and untested meant. It's all there for you.

I look forward to your 8 hour run though. :) Good luck!

awesome ram， if it's Micron D9GTR, 1.65V is quite cool for this.

Ofhorse it's not, thats Elpida Hypers, micron will never do that w/ only 1.65v, but thanks.

yeah,it's my mistake,i fould some super talent ram use D9GTR and i knew that 1.8 or 1.9v should be needed to reach this frequency, then i fould super talent 2200 c8 use elpida hyper ,so it makes sence now:yepp:

The original fan on the H50 proved to be quite ineffective and would actually cause the chip to overheat with 1.44v at load. I felt like I needed some massive increase in airflow, so I took the fans out of my broken vapochill and did a push/pull on the radiator. Needless to say it runs much cooler when doing heavy loads. I also haven't tweaked the memory or northbridge very much, I'll do that eventually. I just want to see a few more mhz than my 940 gave me.

I will have a stable posting later, but for some reason when it runs prime it will occasionally drop the multi to 8x without warning and it doesn't matter what temps look like. CnQ is disabled along with turbo so I have no clue whats going on.

Edit: Went back and checked. Nothing for power saving is enabled in the bios. I have no idea what's going on to cause this. Should I maybe use a different bios than 905? I did a search and it said that it was supposed to be fixed in newer bios's. The htt on this board also fluctuates far more than any board I have ever owned in the past and it jumps 2-3mhz quite often.
