I have my I7 920 running at 3.8ghz with a cooler master v8 and have a couple questions I was hoping someone can help me with.
I was looking at average temps of people running this setup and found them to be all over the place. My average temp is 80c running prime95, using core temp and real temp programs for my reading. Is this too high? Im running this test setup outside of a case (should my temps be better inside a case? It will be in a Antec 900).
Lastly, running core temp and real temp apps only one core is riding high in the 80c range all the others are 76c and below, whats the safe way to average this?
It sounds a little high to me for that cooler. Whats the core voltage? Mine at 3.8 is set to 1.37V. I have the zalman 9700, temps running prime95 with core temp stay under 65C after several hours. This is in my antec 900.
hey guys thanks for the replies! Well, I figured out the temperature issue, and it was my fault. Hyper threading was still on, at 3.8ghz and full load prime95 im at 69c on the highest core and 62c on lowest outside of case.
I guess the question is if I should keep HT on and lower my overclock or keep it off and keep a higher overclock. Ive been reading around and it looks like normal applications see performance increase with it on.
Ive read around, and though its not the norm HT enabled can cause up 10 10c difference in temperature. I have it disabled for now, I run 80c average at 3.8 with it on now and 68c avg with it off.. thats huge
Odd enough, Im bringing up this thread because I had my computer idling at stock speeds for sometime, I decided to get back into overclocking it and now when Ive come back to put in the same settings Im idling at 40C and when overclocked at 19x200 Im reaching 75-85C, what in the world has happened? Im using ARTIC SILVER 5 and I dont think the paste could have been ruined this quickly? Room temps are slightly warmer but not in any way that different.
Well the i7 920 can burn 150w at stock speeds so the power consumption when overclocked is going to be somethine crazy. Also case ventilation makes a huge difference. I recently changed the air flow in my workstation because No2 Opteron was running 6c hotter than No1 Opteron even though there side by side. I swapped the cpu's and heatsinks around and no difference. It turned out the second cpu was getting the warm air from the first cpu and making it run hotter. I reversed the front case fans and installed some 120mm fans in the side to push cool air onto the cpu's and now there is only 1c difference.
The Opterons only use 65w and run very cool as it is but you might find this makes a big difference with the i7. Redo the heat paste, setup some extra fans and see what happens. BTW does the cpu cooler actually feel like it's reaching 80c. If you can hold your hand on the base or one of the heat pipes then it's either not running at 80c or the cooler is not doing it's job. Also try and get hold of a Thermalright Ultra-120. If the Thermalright can't keep it cool then nothing will.
I've read that some 920's are actually better chips that have been labeled and programmed as the cheaper model to meet demand. Some 920's are actually 965's for example. They are both the same chip, but one has more imperfections and therefore runs hotter.
Using a Core i7 920 D0, Asus P6T Deluxe v2, Arctic Cooling Freezer 7 Pro Rev.2, and Xclio Windtunnel chassis, I'm getting idle/load of 60/90 at 4ghz. Thats a little too scary for me, so I underclocked it and turned all the fans down to silent (and with a solid state hard drive, it is quite quiet overall) - which for me is fun and cool in a different way. At stock speeds and low fan settings mine idles/loads at 45/65.
