CPU Upgrades / Re: The 1.6ghz Sonnet Encore MDX overclocking project
« Last post by indibil on April 22, 2024, 09:50:39 PM »Hello! How fun this post. I recently got a Sonnet Duet 2x1.83GHz processor for MDD and after reading this post and Project Nova, I decided to go up to 2GHz. But I come to give bad news.
At 1.83GHz the Dual processor is totally stable, but when it reached 2GHz it had problems, and sometimes the diagnosis indicated problems with the RAM modules, so I blamed them first.
Once the correct RAM modules were installed, I tried to install the original MDD aluminum heatsink, but unlike Project Nova, mine did not fit well, look at the attached photo with the thermal compound marks, only part of the processor. I show it to you so you can verify it, because bad contact can burn a processor.
After reinstalling the Sonnet cooler, I replaced the 50x50 fan with an 80x80 fan. And it seems that GeekBench worked well and with maximum temperatures of 54ºC.
But I decided to do a more intensive test. I ran GeekBench tests one after another, and always at most the third test the GeekBench would freeze and when I ran it again, it would take a long time or freeze again, and sometimes appears panic kernel. The temperature was beginning to approach 56ºC.
I think that the dual processor works at 2GHz but very at the limit, probably with insufficient voltage for stability, because perhaps some installed 7447s have more stability at 2GHz than others, perhaps mine do not, others perhaps do.
I would need the combination for 1.92GHz. Does anyone know her?
I simply wanted to provide these details to those planning the overclock.
