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

[Zeus]

I know but for testing just ram there are much better tools, like memtest in windows. Blend is very good for testing AMD cpu's as it is testing the cores and the CPU-NB thoroughly.

I still can't get my head around the 8 hour Prime thing, two hours is more than enough for me. Prime for pleasure maybe?

[muziqaz]

When all the ram sticks are working full load, then cpu NB is working full load And come on, I had millions of times when cpu would fail after 5-6hours of priming.two hours is way too low Unless we are talking about different kinds of stability
My kind is being able to fold 24/7, 365 days a year, for other casual gaming sessions

tests shouls consist of 3hrs prime + 50 pass 20k linx that.

Prime find erros in NB/RAM very good, as linx is amazing for fine tunning your CPU.

My newest 1055T goes 1.35V LLC enabled (about 1.375V at load) 4050MHz, 3h Prime Large FFT. Noctua NH-D14

Other chip wasn't like this. But I think I will sell this too, bought again 4pcs of 555 BE cpus <3.

Supernice overclock Krjalone!!

@Krjalone

[Particle]

Rock and roll

Very nice chip you've got there Krjalone.

[ah_khoo]

i know this might sound off topic, but i really can't think off any other thread to ask about this:

is there any 1090 1021EPMW user(s) here? I've browsed thru d chart but can't seem to find one. just gotten mine, but will be able to test only tonite. wanna check what would be d estimated clock d chip can hit... thanks in advance...

4,5ghz 24/7 .. awesome

nice oc with 1.45 cpu volt. what bios version did you use? thx

[stangracin3]

is WCG good enough? ive already tested my ram and mem ive just been bumping up my cpu by half multi.

Hmm, after all this cpu doesn't seem as bad as i thought:



Watercooled, 20ºC ambient.

Test Linx now at 20k problem size, I will be happy to know that it passed.

[Zeus]

No need to. If it can pass Prime for an hour like this it is good enough for me, hence i didn't doo the required 8 hours Prime. Please do not quote images.

[FlanK3r]

good Zeus, a bit better (+14 MHz) than my aircooled 1015 chip . No, seriously, nice chip. My second Thuban can not this (top at 4130 MHz).

[I.nfraR.ed]

Zeus, really nice cpu you have . I have a 30min Prime95 screenshot at 4310MHz and 1.5V, but the temperatures were a little bit hot for my liking after about an hour, so I didn't pushed it forward and settled with the current frequency. I'm not sure it's still capable of doing it, because I had a better cooling at that time.

[FlanK3r]

its strange with WC and high temps

@ah khoo

im using the same motherboard but with a 1055T. Just notice when stress testing with linx @ 4000 and 4100 frequency my cpu was throttling down. How bout yours?

cant seem to find how to disable cpu thermal throttling in bios (maybe there is no option)

what's the load temperature when it dose that ?

im using a bios temperature controlled fan speed, so at 40C its silent (50% fans speed) and by 45C its at 100% and noticeable, but not uncomfortable. if i left in on all the time my temps would be about 42C. i also left my exhaust fan at 50% which is probably not recommended if i wanted to see stable, but is my 24/7 setting.

[mrcmark]

what's the load temperature when it dose that ?

50°C at 4000+ mhz and 52°C at 4100+

at 4000 mhz the throlling happens seldomly but at 4100 it happens a lot. I think my ambient is 28°C.

Im stress testing with an open case and a big fan blowing on the motherboard.
