Core i7/X58 Overclocking Thread

[safan80]

I had Dtek V1 with washer and 5.5 nozzle on my E8600. When I upgraded to i7, no way was I taking my loop down twice and no 1366 bracket available, so made my own bracket and left loop as is. First couple weeks, I used DTEK and nozzle on my i7.

The first 1366 that came available was GTZ so I switched to that. With same ambients, I got ~2C better on load at same overclock looking at 4, 4.1 and 4.2 by switching to GTZ with backplate vs DTEK as described above. I had probably 15 runs prime/linpack with DTEK and more than that now with GTZ, any way I look at it short runs or long runs, realtemp usually records about 2C less max temps and looking at avg temps with GTZ.

Though that is not exactly what you are asking, and unfortunately the same laziness that prevented me from taking my loop down more than 1x until 1366 was available, also prevented me from knowing what difference between nozzle on vs off, but given it was 2C from GTZ with it on, my only comment was it was not too bad with 5.5 nozzle on. But cant tell you if would be same or little better with it off, or for that matter a little worse (theory doesnt always predict results). Not to mention I made no effort to control any other variables, though my ambients are usually very controlled.

I never used the nozzle on my dtek v1 and I can tell you... the flow rate is a lot higher on the dtek V1 is a lot higher than the GTZ. my loop design remained the same for the most part. the cyclone is my v1 ek res is pretty weak with the GTZ in the loop by itself compared to the no nozzle V1 dtek with Mcw30 in the loop... any chance I could get you to send me your dtek mounting plate?

maybe HT isn't really needed ?

I need it...In my favorite game ETQW the cpu usage is 75% with HT off and 35% with it on.

the giga board was what i was initially going to get. But i ended up finding a good deal on this MSI. It was under LN2 at one time and carried a 965XE to 5.4ghz. But i am not happy with it as far as overclocking goes. It has a great layout, love it for that and its a stable board. Im gonna hold off for the EVGA X58 Classified so i can run tri-sli at full 16x. Next week will be interesting though to see how 3 core 216 260's run on the MSI board being that 1 slot is only 4x.

I don't like Evga's current X58 bioses and one thing I hate about the board is whenever I reboot it has to power down and then power back on. the Ga x58 ud5 doesn't do that. Id hold off on the EVGA X58 Classified they need to get better at bios writing first.

I would have been happy to send what I made, but threw it away, and after seeing it you probably would not want it anyways. My temp "homemade bracket" was a 30 minute cut two pieces of thick aluminum strip and drill a few holes and place over the bracket that came with it....see pic.

And totally agree the Dtek without nozzle had much higher flow than GTZ. In fact the whole reason I bought washer and nozzle for DTEK was not for better temps, it was to slow the flow rate down. I have silent ddc 3.1 pumps, but without enough restriction they make a cavitation sound at high flow rates which is annoying. It sounds like air, but it is not air. But pinch the line enough and slow flow down, sound goes away. All 3 of my identical pumps do that. The GTZ has enough restriction by itself, so no water cavitation sound.

I would of used it lol... I got so many fans going I don't hear any of my pumps... in fact they are slient when I don't have my fans running.
