Haswell on water (Speed-Demon) LOG

post #1 of 2
Thread Starter 
Ok so for all those that don't know me I've been overclocking for awhile with sandy-bridge and have successfully gone up to 5Ghz on water with my chip. I'm pretty decent at overclocking... or I'd like to thing so. Since my Mobo was dying on my old rig I decided to upgrade to haswell (an idea that I now think was stupid on my part.) Either way lets get past all that. It's my sig rig and I thought I'd enlighten people a bit of my first impressions of haswell as an overclocker. I think I got quite a good chip as far as needing voltage goes. Down below I will log what I've accomplished on my XSPC RASA waterblock with a MCP-350 swiftech and finally an RS240 Radiator. On the Rad I have 4 Yate-Loons capable of spinning up to about 2k.

So far I find my loop to be lacking the ability to cool my haswell sufficiently. Something I think I may need to upgrade. Anyways here's my results of my overclocking session tonight. This will be a log so I can both keep track of my progress and to let you guys know how my chip is doing.

8/12 - Early Morning

I decided since my rig had been functioning well for over 24 hours to throw it at the wall and drive the clocks up. So I started out easy. A 4.1Ghz overclock via Gigabytes OC profiles on my board. It was stable in IBT and I was happy with that. What I wasen't so happy about was the temps which were in the high 70's low 80's Celsius.

I then got a little over zealous and went to medium. I should have known that it would bump the V-core up. If I can remember correctly it boosted it up to 1.3 ish V and I threw it on IBT to test it. I shouldn't have done this and it caused the CPU to throttle and throw it into a thermal status warning... at which point I immediately stopped IBT and was slightly pissed... both because I seen the V-core go up that high (which I knew I should have looked at it in the BIO's but didn't) and because of the temps I was getting.

Next, I thought my issues in the temp department might have been from a poor thermal paste job. I used a spread technique instead of the rice and pressure method. So I went and took the block off and cleaned the TIM and reapplied using the rice grain method. Retested and still no dice. High temps still using Gigabytes medium OC profile.

I will add a note that I don't like using OC profiles but I just wanted to see what my chip was capable of and go from there.

So the next thing I did was pop into the BIOS and loaded stock settings. I then set XMP for ram and threw the VCore to 1.25 V and ramped up the Frequency (turbo core) from 4.3 onward. I was stable up to 4.5. 4.6 was not stable at that voltage. It froze when I ran IBT and didn't blue screen. This is where I ended my session. at 4.5 Ghz temps went all the way up to 92 degrees Celsius.

So at this point its either get a new water block and radiator or push my luck and de-lid. I think I may do both... but starting with the first and then ending with the last if need be.

Edit: Some baselines. My 3.6Ghz stock temp is around 66 degrees Celsius... at load in IBT.

Ok so I'm posting what I believe the theoretical limit of my chip with my setup. Granted it isn't tested tried and true at that clock. It's hot and quite frankly I wouldn't run it 24/7 at those temps and rightfully so. I'm going to order CLU and try my luck at de-lidding. Hopefully, I can buy about 10-15 degree's Celsius. I'm beginning to believe that a better RAD and Water-block might be helpful but de-lidding and CLU will be the most beneficial. It will likely take me a week or two to get these things done. I will likely be buying a new GPU soon since mine is a bit long in the tooth... I don't game much on the PC but it's always nice to have that option since I do play some strategy games and things on it. Overall though it is mostly here to do productivity, render, trans-code, and the like. I'll also post up some pictures of the tower since I just realized I don't have any up at all. thumb.gif
