Hi, I have just overclocked my cpu to 3.4ghz for the first time.It is running at 46C at idle and under load for 10mins it got up to 61C(Rise of Flight).

I then turned the game off because I was not sure of the maximum safe temperature of this Cpu under load and 61C after 10 mins seemed a bit high?Do these temps seem normal and what temp should I let my cpu get to under load.

I am using a CoolerMaster BLACK CM 690 CASE with 3 120mm fans and the stock cpu cooler.

Any help would be much appreciated.

Tim

Voltages?

It's a bit higher then most people would like it to be but not for stock hsf.

Also, it's your idle temps that are too high.

Get another hsf for your cpu if your going to overclock.

Hope this is the right info:

VC1:1.22
+3.3v:3.28
+5v:3.00
+12v:3.26

Thanks for the help.

No we were looking for te vcore voltages.

Lol.

I think the vc1: 1.22v is vcore, he just put it down differently. Probably has an Asus mobo if I am not mistaken.

He's fine for his overclock but if he wants to push it any further he needs better cooling. The stock hsf is just asking for it.

Yeah bro... get a better cooler for 25$ and you can get i high overclock.

I have the core contact freezer and you can see by my sig that i got my e8500 to 4.93ghz with it.

Heh... 1.8v though... How did you manage that?

Also, I got a question what is the best stable oc you can get at about 1.4v?

Not 100% stable but stable enough for me.

Like i said. I would much rather have my CPU at 4.3 Ghz and get a BSOD once a day than have it at 4Ghz and it be perfectly stable.

Why? Isn't getting a BSOD a waste of time? And how do you benefit from 300Mhz besides benching. And if your playing games 3.6-3.8Ghz is enough.

Well, I can see what he is saying because I've done this before but it gets kind of annoying and you tend to want to find the stable overclocks. As for me, I couldn't get 4 ghz without running into stability issues. Sometimes I feel like leaving the cpu as it as, sometimes I think it should be kept stable.

@overshocked

LOL!

4 ghz isnt to shabby. But i need about 4.5Ghz so that my cpu doesnt hold back my gpu's.

Hmmm, do you start to see a good performance increase at about 4.3 ghz with your e8500 chip? That's where mines really shows impressive response performance.

The rewards you see from high CPU overclocks are also fairly graphics card dependant. Some cards will get throttled by a slower CPU, especially if it's running on a lower FSB.

When I had an 8800GTS (the 320MB version) coupled to a P4 3GHz, it only started opening up performance-wise when I was hitting around 4.2~4.5GHz.

At 5.2GHz (my record) it was dominating 8800 Ultras... until the bit -uh, horrible person who had the Ultra overclocked HER CPU. Which was an E6300, so it didn't have to go very far...

I have kept my overclock at 3.4 ghz and under load it seems to now only going as high as 59C and at idle it is still at 46C.Is this ok to keep or will it knacker my cpu?

Get a etter cooler dude!

Those are alright temps but why not get a better cooler??

Yeah, get another cooler. The stock hsf is exactly just that, a stock heatsink fan.

How are you getting such high idles but decent load temps?

@Mugz

Uhhhh, I only got integrated gma 3100 graphics and I can tell that it really shows a huge difference at about 4.3 ghz+. Couldn't go any further really with my old stepping chip without shoving more then 1.55v... Graphics don't make THAT much of a difference at a certain point. I don't game anymore... Although what I have is more than enough so I'm not complaining.

I was using speed fan and it was giving me the wrong readings.I have made sure of this by checking it against Real Temp and Core Temp and the both give me exactly the same readings.I have bought a new cpu fan a MiniTyphoon90 and have overclocked to 3.6 and my idle temps are at 34C.

The only thing I changed to do this was the fsb to 380, is this ok to carry on in the same way up to 3.8 or will I also have to change other settings apart from the fsb?

I have also noticed that my readings in COreTemp and Real Temp show that the multiplier is going from 9.5(as it should be) to 6.0?Is this just a problem with these programs or is my speed reall going as low as 2.4 ?

Reply to Tim1981
Ragsters   08-21-2009 at 05:39:56 PM

Yes the speed is really going to 2.4Ghz. This is called intel speed step and it is enabled in your bios to save energy. You can disable it if you like. All it does is drop the multiplier when the computer is idle.

Yeah, disable speed step and add some more vcore.

Thanks again for the hellp.

My system has started rebooting under load.I have so far overclocked to 3.7ghz.

The V core is 1.225v, Is this the cause of the reboots and if so could someone suggest a good V core setting for 3.7.

Yea I dont think its getting enough juice feed it more vcore untill it doesnt reboot shouldnt take to much more if your able to fully boot into windows I recommend you give intel burn test a try afterwards. It'll let you know pretty quick rather or not theirs enough vcore for your current oc usually with a bsod. For mine at about the same oc I needed 1.26v but i have an e8400

I tried upping my V core and noticed you cannot type the value in manually so just selected the next click up from 1.225v to 1.2375 this was while at 3.7 ghz.

Upon restart I recieved a message saying that the overclock had failed and it gave me a choice between default settings or to configure new settings.

Could this be something to do with my ram timings:

:5-5-5-18-3-52-6-3-3

I also noticed that "Max cpuid value limit" is currently disabled.

I have resorted back to 3.6 for the time and my temps are still quite low.

Any help, much appreciated.

Make sure ram is running in spec keep trying to up vcore dont just stop after a little bit. If you leave vcore set to auto for the 3.7ghz oc does it post and boot into windows? If so use cpuz and take note of the vcore it sets for that oc will give you a good idea of the range you should be testing in.

When you say dont just up the v core a bit, that confuses me.I was told to only up the V core in small amounts so I upped it the smallest amount possible and tried to reboot but it did not work.

Are you saying I should try and up the V Core more all in one go.I need to understand this because otherwise things might go wrong.Also my system is curently at 3.6, should I up the V Core and the FSB at the same time?

Many thanks

Tim

I usually skip a little when finding stable vcore and go a little higher to speed up the process, a little at a time usually isnt enough when your oc is pretty high. What is your current vcore setting for the 3.6ghz oc

The E8500 thermal specification is 72.4 or 74.1 according to your processor's stepping degrees celsius as you can see from the processor spec finder using the following link
