this is what gallium does to Alu,

...hey, VonDutch is back smile.gif - and very right he is, never mind that CL products give a warning right on the package about aluminum...I was going to do my Direct CU ii cards with CL U, but in the end did not because there was a tiny bit if aluminum visible on the die contact area:

Guys is it possible that chip just wont last higher voltages ? I can currently go 4.7GHZ@1.235V and it goes fine for 29 hours in prime but then one worker fails. So I logically set 1.25V and one would think it will be completely stable, but to my surprise, prime itself crash after 8 hours or so. So I might end up with 4.5GHZ@1.2V again.. But it doesnt make any sense, as I see ppl here having their chips on 1.4V etc., and 1.25V isnt really high

Did you catch my post on this matter. I posted several days ago.

Yes I did, but we were talking about 1.4V. It seems impossible to me that chip could not stand 1.25V, that would be just ridiculous.

PS: SmallFFT test on 1.4V is quite fine, but just blend BSOD immediately. Seems to me as something with RAM, not the chip

ivy is also about working the vcore very carefully,
made me think about something sin0822 said in his guide, how ivy behaves under ln2 etc..
i wouldnt go from 1.235 to 1.25 in one step tho, just stick to the 0.005V increments , and first try 1.240, then1.245...and then 1.25V,
not sure what else there could be wrong with your vcore up, and getting worse results..

Under LN2/DICE: Temperature is more important for high clocks than voltage is when it comes to Ivy Bridge. Also under LN2 higher vcore might not yield a higher clock, as it will add more heat which can have an opposite effect. So while at 1.84v I might do 6.6 GHz if I increase to 1.86 I can only do 6.55, but if I lower the vcore to 1.83v I can still only do 6.55, it is all about working the volts very carefully. I should take a second and note that Ivy Bridge is an extremely tough CPU, it is very hard to kill, however you can kill it if you go above 1.6v on air and ~2.0v on LN2. Ivy Bridge also seems to be more resilient to degradation than Sandy Bridge was, however the heat produced by the CPU can cause degradations when above what Intel recommends.


the way i do my oc's, is find my stable vcore for any oc, then change to offset, see if it is stable,
then i just at 0.005 or 0.010V, and let it run like that, never had problems with it doing it that way,
so i think its strange you cant/couldnt at more vcore smile.gif

Well, 1.235V failed after 29 hours. 1.245V gave whea code 19 after 8-9 hours, and with 1.250V prime just crashed after 8 hours. I dont remember if I tried 1.2400V though, but I think I did.

it is very strange, thats for sure,
if i look at the vcores you used, i would almost say 1.230V vcore is the one you need ..lol

i would fiddle some more with the 1.235V vcore you had, it ran prime very long after all,
29H is very stable already see, you prolly wont see a crash with normal daily usage (1-2 a year?),

if data is very very important to you, i would surely go on looking for stability,
if your a normal daily user, like me playing games, browse a bit online etc, it isnt a big deal if it would crash sometimes,
windows on its own can do that too...lol..

answering PM's, couldnt resist to answer on some posts tho ...haha.. tongue.gif
you sure thats Alu and not the heatpipes (nickel plated) that are flattened between the copper plate?
