How-To: 8 GHz on Bulldozer

Overclockers.com · 11-18-11, 02:07 PM

Quote:

These are full instructions for how to go after CPU Frequency World Records on Bulldozer. This is a cleaned up and prettier version of my original Bulldozer overclocking instructions published on the forums, so I suggest you become a forum member to follow the bleeding edge developments that go on regularly there.

Hopefully this will be helpful for anyone out there with Bulldozer and Liquid Nitrogen, and for everyone else I hope it uncovers the secrets of how its done...

Nice! Cheers Matt

Brolloks · 11-18-11, 02:41 PM

A big CONGRATS to you Matt

, that is an accomplishment to be proud of, I sure am gald you are on our benching team

I just love your frosty pics, looks like a winter wonderland in the world of benching

Nice write up

I.M.O.G. · 11-19-11, 04:34 PM

Thanks guys. Its everything a person needs to know, after this, it's just a matter of finding the right chip.

IJAHman · 11-22-11, 09:24 PM

This is crazy but awesome! 8ghz!!! men that's wow!

Congrats & Cheers!

kskwerl · 11-23-11, 03:40 PM

17th in the world! That's nasty!

I.M.O.G. · 11-23-11, 03:46 PM

Thanks, 13th now with 8.123GHz:

Still working on it, but thats the best I could do with a couple more hours spent working on it last night.

Very nice indeed

i got a ? what is the point in doing this xtreme overclock? just bragging rights im assuming is there anyway that anyone will actually use the comp like that for the whole time they got it? this is not a flame im just wondering. and what does it cost to get that stuff

The point is to see how far the hardware will go, that's all really.

No one will ever run the PC that fast for it's entire life; the PC was just stable enough to load the OS, increase the FSB/bclk, and open CPUz to validate.

An old, used pot/evap can be had for ~$100, but new ones can cost over $200. LN₂ is usually $1-2 per liter; dry ice can be had at Publix for $1.50 per pound.

The point is just to enjoy the hobby really. The score is just to try to set records by seeing how far your hardware can go if ran correctly. We have a benchmarking team here so as a group we all compete against eachother, and against other benchmarking teams.

I do it because there have been over 60,000 CPU frequency submissions at hwbot.org. Out of those submissions, I'm currently ranked 13th. I think that is kind of neat. The challenge along the way was the best part though, even if I never got that high of a score I've had a fun time learning - finding other guys around here to teach me, learning how to insulate, learning how to run the system on LN2... figuring out which voltages it helps to tweak, and what combinations of frequencies work the best.

So if you were just starting out, you'd see how high your clock speed can go on air cooling. Then maybe you'd see how high you can set it and still run superpi or wprime. Then maybe you'd try out watercooling and see if that increases your limits. Ultimately if you are into the tweaking, you run benchmarks just for the fun of the hobby and competition, and compare your scores to everyone else running those same benchmarks on hwbot.org.

As for cost, I paid $300 for a 50L container I can get filled with LN2. I paid a bit over $200 for a copper evaporator to mount on my processor and pour the LN2 into. I pay 75 cents/liter for the LN2 each time I get my container filled up. It was expensive starting out to get the container and the cooler. But for less than $40 for 50 liters, I can spend a few nights playing with a computer thats on the very edge of stability and see what I can make it do.

wow! congrats man!

I.M.O.G. · 11-29-11, 07:37 PM

Improved to 4th today, 8.235GHz:
http://hwbot.org/submission/2225833

High FSB and lower multi did the trick, just had to figure out what this new CVF liked.

IJAHman · 11-29-11, 11:16 PM

Wow! Still improving. keep it up man!

ToRpEdA667 · 12-08-11, 02:44 AM

Wow. Great Job Man full Regards

I.M.O.G. · 12-08-11, 06:36 AM

thanks

still going to make one more attempt, just need to find the time.
