Here are all the screenshot results and validations:
I wanted to see how the slushbox worked under a real stress and if the chip would stay stable. The slushbox doesn’t deal with loads too well, but is still kept below 32C at all times. I believe if I had a good enough water setup, I could attain this stable speed no problem without any slushbox at all.
I ramped up SuperPi to see what this chip can do. On my previous deneb chips, SuperPi 1m was my bread and butter, my favourite benchmark to run. Since SuperPi is a single threaded application, I imagine if I disabled some cores or ramped up only one core I could get better results.
SuperPi 32m @ 4500MHz SuperPi 32m @ 4571MHz
My first run was kind of on the safe side. To avoid a crash. However for second run I ramped up the processor a bit. This was the max I could go while still using all 6 cores. Once again, being single threaded, disabling cores might be able to help my clocking.
wPrime 32m @ 4500MHz
wPrime 1024m @ 4250MHz wPrime 1024M @ 4409MHz
PiFast @ 4500MHz PiFast @ 4553MHz
Cinebench 11.5 @ 4250MHz Cinebench 11.5 @ 4427MHz
CPUZ SS @ 4730MHz – Validation
In the video I attained a speed of 4.75GHz, however it was not stable for validation nor screenshot. It was only a taken as a video clip. The cpu did not last very long at 4.75GHz and crashed soon after.
Hey guys. I did some more tuning, got more results. So I am throwing together my second slushbox blog. To see the first one, click here.
I tried to place my rad in the cooler this time so that the ice covered more surface area. This resulted in idle temps of 0-1C. So i pushed my Phenom II X6 1090T even further. Here goes my second set of results.
4.806GHz All 6 Cores @ 1.648Vcore 1C idle – Validation
It took me an hour to get this validation. I could only previously validate 4.73GHz. I needed to reposition my rad for better surface area of ice. Then I had to wait for my temperature to drop to 0-1C before I made the final push. I couldn’t get any further without going above 1.648Vcore. Here we have it, 4.806GHz on the slushbox. Can’t wait to see what this can do with DICE.
4.902GHz Core #1 @1.648Vcore 1C idle
I chose 3 of my chips cores for this result, meaning I had to disable 3 in the bios. I had previously tested all 6 individually, and the best clockers were cores #0,#1, and #4. The best of the three was core #1, the one which I decided to push for this screeny.
SuperPi 1M – 4.7GHz @ 1.616Vcore – 14.555 seconds
This is a very fast result. The upper limit for my cpu in 1m. Again, this result only uses three cores. I believe I could improve on this score by tuning my ram a bit more.
SuperPi 32m – 4.608GHz @ 1.616Vcore – 14 minutes, 53.148 seconds
This is the first time I have ever broken 15 minutes in 32m without using dry ice. This score could also be improved through a little ram tuning.
UPDATE: Low Volt Overclocking
I wanted to see how far this thing would go without using insanely high volts. It’s pretty amazing what a little bit of cold can do.
This was my boot speed. 4GHz using only 1.296Vcore. That is stock for these thuban chips.
4.5GHz only requiring 1.44Vcore. These things LOVE cold!
As always, these 1090T’s follow suit with their x4 brethren and respond well to cold. I can’t wait to throw some DICE on these and see how they scale. I’m looking for 5200MHz+.
Thanks for checking out my second session guys. I hope this was interesting. And I also hope to inspire many others to put their Phenom II’s under cold. You will not be disappointed with the results.
