Hello, guys I am new in overclock CPU, I got question to ask, about CPU temperature, because I just overclock my core i7 980x to 4.0 ghz using the asus rampage auto cpu level up. the idle mode temperature is around 45-50c at full load when playing games highest temperature 90-97c, using an cooler master V6 air-cool. The main question is is it safe? Or I should replace the air-cool to crosshair ready made water block. Or don't overclock?
ps: sorry about my English.
First of all, yes, those temps are probaby safe if you never go any higher. But, gaming isn't usually full load, so I'm going to tell you yes, that is way too hot for only 4gHz.
The Asus software probablyused way too much voltage for the OC you have, which is abig contributor to the heat. Go into your BIOS; what voltage is it telling you the CPU is set to? You may want to drop it.
thanks. for the advice, so i need to do is set it to manual overclock, i am at office ATM, so can't tell you my current voltage setting. i just read some forums online it telling me my cpu max voltage is 1.4v. btw i forgot to mention, my this system is 2 years old, i believe my coolermaster v6 cpu air-cooler is full of bust, haven't clean it for 2years. lol, maybe that is given me the temperature problem.
btw, will u recommend a crosair hydro series H110 280MM extreme performance liquid cpu cooler?
Yeah, pretty damn hot. I can't find a reliable source but I would guess the Tj. Max of your CPU is about 100C, Tj. Max is the temperature at which your CPU will start to automatically throttle itself for safetly measures, basically you're at the limit of what the CPU is supposed to be.
1. Put the voltage down manually in the BIOS (voltage is the main cause of heat), I would say put it down 0.010v at a time, run a stability test in Windows, then if the stability test passes put it down another 0.010 until Windows crashes either at startup or during stability test, when this happens return the voltage back up 0.010v.
2. Try another monitoring program, Speedfan was showing me very worrying temperatures like yours but OCCT and other programs showed everything fine.
If that does nothing then someone else will have to take over because that is pretty much as far as my knowledge extends.
No, I do not recommend CLCs, or closed loop coolers, like the H110. I think they're a waste of money; if you want cooling performance, get a high-end air cooler, not an overpriced liquid cooler. The Phanteks PH-TC14PE isa great option for overclocking. If you have the budget for an H110, then you could get the PH-TC14PE and two or three really nice fans, like Noctua NF-A14s, and have a quieter, equally performing cooler for less money.
You are pretty new to the forum, aren't you?
Good advice, though. 4gHz should be more than fine at 1.2V on a 1366 CPU. I'd rather steadily raise the voltage, than steadily drop it. Take it pretty low, at least to stock voltages, then stress test. IBT is a nice, quick and dirty test, but I recommend a full 24 to 48 hour P95 run.
thanks you so much, for the advice, will try to lower the voltage, hope i will not FRIED my CPU.
Lowering the voltage will only make it cooler. Don't worry, 95C isn't close to frying it yet ;)
oh ya, i got 1 more question. can i just overclock my cpu. and don't overclock DRAM Frequency? couse all the 6 ram slot are full. afraid not enough airflow. btw the memory which i am using are KIngston DDR3 1600hz. total 12GB, the ram stick part no; KHX 1600C9D3K3/6GX @ 1.65v.
You can, but don't worry about RAM; it doesn't get hot enough to ever worry about.
what is Tj stand for? and thanks for the advice.
ok back from work, i reset to default stock speed, here is the temp at idle 35-39c, at full load highest temp of any core is 65c.
TJ max is the highest rated operating temp for the hardware. You don't want to be at TJ max, you want lots of room to work with temp wise.
Sorry yeah I am, did I say something wrong?
No, not at all! Just welcoming you to the forum :)
Ah right, thanks!
