i7 3820 - 4820 Overclock Club - Page 56

post #551 of 6491
At 4.625 with RipjawsX 16gb quad kit at 2000mhz xmp profile I hit 107-113 Gflops on IBT. As far as 3820 or 2700k being quiter? I don't understand that as that is up to your cooler. The 3820 runs incredible cool for the overclock though. 4.625 is my 24/7 oc. Temp idles are 28-31 and hit 62-65* using a h100 normally while stress testing. Once I clean my fan filters it should drop back down to 25* idle and 58-62* while stress testing.

Very similar setup to mine, however my temps are higher than yours at the same clock. mad.gif

Power consumption differences between 2600K, 2700K, 3820, 3930K:

http://www.xbitlabs.com/articles/cpu/display/core-i7-3820_8.html#sect0

Can't remember where I saw the benchmark showing temps (forgot to bookmark it).

To be fair, unless you've tried the different chips yourself for the same type of process (eg gaming) it's very difficult to compare and offer advice. Not many people who have bought a new system based around either the 2011 or 1155 are going to admit they might have made the wrong choice; once you've decided on a new setup it's kind of nice to think you have the best one you could afford for the job you wanted it for.

I have alot of fans in the case and used the noctura tim. My case flows alot of air it seems.

That chip also was a ES. Most ES seemed to have a problem overclocking past 4.5. Once it released 4.625 is the minimum and 5.0 isn't uncommon at all. Any reviews done before the end of feb i take with a grain of salt. Just like the ivy bridge leaks. I take them with a grain of salt till its a production cpu.

Push/ pull?

Hopefully soon I'll be able to buy more/ better fans, with the HAF-X I can fit 1x 230mm, 3x 200mm, 1x 140mm and 4x 120mm if I use push/pull on the H100, I could also probably fit in another 2x 120mm if I ghetto-rigged them with cable-ties. tongue.gif

If I can fit all those fans in I'll have airflow like a beast. thumb.gif

My setup is just push right now. I am going to try and get two super slim fans to help pull. My case has the two 120mm fans pushing exhaust out through the h100 cooler and one 120mm fan on the back. It has 5 or 6 120mm intake fans though.
As far as power consumption I found a great review and breakdown of the power consumption.

Compared to its main competition, the i7-2600K, the i7-3820 has about 10% higher idle and 20% higher CPU load power consumption. This is a significant increase, but one must keep in mind that the Sandy Bridge-E chip does have 25% more power-sucking L3 cache, a much larger integrated memory controller, and a revamped PCI-E controlller. You aren't really getting much additional pure CPU performance for those extra watts, but they are an end result of the greatly enhanced PCI-E bandwidth capabilities of the chipset.

I got the same case and it rocks. 2 front intake fans and 1 one in the bottom and the side grill can fit a 200mm fan. It's like a cool autumn breeze in there. On top of that there is room for 240 +120 radiators in a midi tower.
