have you clocked it higher after deliding to see how fat it can go? I plan to delid this one on tomorrow and use CL Ultra (had great results with it on former chip).

The delidded chip is L221B598. I haven't run it too far yet, put it on the ss to try out the IMC when it was giving me trouble & ran some IBT at 5Ghz. 1.44V. I do have some liquid ultra coming (was hoping for the weekend since I need the 7970 shim coming with it) & will try it on the cascade again to see if it does as well or better, it did 5500 @ 1.64V before the delid.

5ghz @ 1.44ghz??? how come? if 4.6ghz calls for 1.3v ... I am now at 1.38v (1.366v under load) for 4.7GHz, I can't see it happening at 1.44v @ 5GHz LOL!
anyways, mine is a different batch and plant, so will see. for now I'm not impressed with my new chip and Cinebench vcore demand he he ...

i'm only running it under water, so deliding will be a must for me if I want to even think about 5GHz ...

I see many of you running IBT. How are temps and stability validation compared to prime 95 small ftt's?

Within 10 c running prime on blend for me. So 24 hours of prime high temp would be 75 c or so and IBT would be 65c . Ambient air temp at 21 c

I personally always find IBT running in Max Mode (all mem used) generating temps higher than the latest Prime95 27.7 SmallFFT. also IBT seems to achieve the same goal much faster than Prime95 does (a few hours versus 1 day or so).
however, quite recently I learned that actually a simple CPU rendering test called Cinebench (11.5 x64 here) verifies vcore stability cruelly and finds instabilities in seconds where both Prime and IBT confirmed it stable ... also the Cinebench test seems to generate mild temps when compared to IBT. Currently I use only Cinebench for stability testing, then on end I confirm it with something else like IBT 2.54 in Max mode 20-30 rounds.

So finally read through all 3200+ posts in this thread and I am getting giddy trying this myself next year. If I don't change my mind until the beginning of next month, when I will be ordering my parts for my new rig and go back to the 3820 build I had planned before. wink.gif
Although I guess I have to do a lot of rereading, when the time comes. Which I have to do anyway as I want to do it when I build in my water loop.

Hey peeps,

I have got my Lid off for some time but i am wondering as i am hitting the voltage wall for overclocking the chip.. 5ghz, 1.52V , how do i get the voltage down but get the Ghz up as i have head room on the cooling.. only hitting 74c.. but the voltage is holding me back...

Is there a way to get higher Ghz with less voltage.. but running higher temps?

Cheers

Imo Voltage wall is 1.6v and max with good temps is 1.55v.. 1.52 is plenty safe...

I was running 4.5 & 4.6Ghz on air, I put the ss (single stage phase) on to test the IMC so the cpu was colder for the 5Ghz at 1.44V. Even on the ss IBT at 5Ghz was driving core temps up to the 50s.
