Overclock: My hobby as a degree project

[4Ryan6]

Hi Ryan.

Sorry for that, has been busy weeks. I will upload the results in next week as late, CPU given me a lot of problems (not good batch) and was hard get it stable with good clocks for 3D test.

My apologies for the long wait.

What CPUs are you experimenting with?

I tested two, i5-4670k and i7-4790k. The problem is that i5 goes dead (waiting replacement) while i7 is good but I am thinking that motherboard in the other hand...

I do not want to say anything yet, but motherboard seems excellent for daily use and basic OC. But the things change with extreme conditions...

I have red the Peltier Sticky and it is awesome. Although I skipped some of the paragraphs and focuses only to the pictures. 🙁

BTW, nice work their Ryan.

How about adding evaporator in your next build?

@ saint19, You can delete everything I posted in here if you want, I won't get upset about it at all my friend! Ry

Do not worry my friend.

I had to move the test for this next weekend. The guy that sold me the LN2 could not delivered until this weekend, so, the good news is that I have a Maximus VII Formula in my hands now.

A Maximus VII Formula, That's a nice M/B it will be interesting to see how it handles the extreme!

Some frosty pictures of the 1st test...hope to do some other in few more weeks.

Results will be uploaded later at home, network is blocked on my work.

After some (ok, a lot) of weeks. I have the 1st results, not the best ones but I have to say than this MB was really good. Stable for all the session (around 5-6 hours) but the most impressive was the GPU. Too much stable, big overclocking headroom and excellent performance.

The idea is do another session, for run the others test (3D11, Catzilla, etc...) and maybe with volt mode, I want the 1st place and with this GPU and a little of effort I am sure that I can do it.

1) 3DMark 01 SE: 124000 marks

2) 3DMark 03: 123590 marks

3) 3DMark 05: 53286 marks

4) 3DMark 06: 40139 marks

NICE! I'm liking those scores. I thought I overclocked professionally, but then I saw this... Lol. I normally use Athlon XPs and Pentium 4s for my OC'ing. Any tips you have for me? Can't use LN2. Possibly DICE, but I don't have a pot, and they cost a pretty penny.

My CPU isn't the best for OC and this benchs, but was really fun.

What about a phase change? That would give you better temps than dice but at a low cost since you don't need a pot. Regarding those CPUs, all depends of silicon, motherboard and RAM. What are you running?

Why not make a shim to sit between the Changers block and Cpu? could be drilled to mount both and would not adversely affect performance I'd have thunked... 3Mm Cu sheet off Egay, halfhours drilling and you'll be set

I really thought we'd be seeing much higher overclocks with LN2 on the 4670K especially with the 1.625v voltage you used just to reach 5ghz?

Couldn't you reach 5ghz with less voltage than that as cool as the CPU was kept?

Temperature wise you've got to be way below any of the CPUs throttling or activation points?

Have you Delidded the CPU or at least considered it?

Maybe you've got a CPU with too large of a TIM gap between the core die and heat spreader?

I'm glad you had fun doing it, and no offense, but to me the results a little on the disappointing side.

I was expecting at least 6ghz or greater out of the CPU with LN2 cooling.

Edit: Why the old legacy benchmarks?

Couldn't you have run 3dM11 or Firestrike so we could have done a score comparison, the benchmarks you used many of us don't even have installed anymore because they're no DX higher than DX9 but you're running a DX11 GPU?

 

[4Ryan6]

I managed to dig up 3DMark03 out of the benchmark graveyard, 149,563 with the settings set the same as you ran it.

The GTX Titan is not overclocked, the I7-3770K CPU is overclocked to 5ghz with Hyper Threading disabled.

Could you share the link of screen shot of the results?

A Titan is much better than a GTX 760, that could make the difference. The problem on this is that my CPU (or motherboard) doesn't want to go above 5GHz, anything above that frequency is a BSoD not matter what voltage I set. The CPU isn't really good it all, even with a single core doesn't hit the 6GHz...not good silicon there.

I am waiting the RAM of the CPU to see what I can do, but I also have plans to test in another motherboard since I am 99% that phase power have something to do.

Why legacy benchmarks? Because I like the old ones (specially 01 SE) and those are the benchmarks that have more points with the GPU that I have plus, 20L of LN2 goes away really fast running CPU and GPU on extreme.

 

[NerdIT]

Awesome! Im really satisfied with the new-gen platform(s)....solid stuff. ! 😛

 

[cvjhch]

I'm looking forward to seeing the results, you're overclocking as a team right?

 

[saint19]

I am waiting for the Skylake arrive for get most of the GPU...Haswell has been sold now.

The link is there below the screenshot.

Granted a GTXTitan is better than a GTX760 when compared stock GTX760/980mhz to stock Hydro Copper GTXTitan/928mhz, but you have the GTX760 OCd to 1235mhz, that would literally stomp a Titan in the dirt.

Are there cold bugs affecting the performance?
