E7500 mobo question.

I did a bit of research a while back when I bought a E7200 and Q9450, so do have a lot of info on the subject. You may know much of this, but I could do with a good keyboard session to keep up to speed! :D

Most the 45nm core2 range, including quads, thermal throttle themselves at around 100C, Tjmax, so anything below say 80C on prime95 multicore full load is absolutely fine.

I'm talking core temps here, as seen in realtemp for example, not case/heatspeader surface temp which is usually 15-20C lower. Perhaps case temp is what you mean when you say 60C limit? 60C case would be 75-80C core.

These days you are looking at the core temp of a CPU, so low figures like 60C as a max are a bit dated. Plus CPU's thermal throttle, so its not an issue - you aren't going to kill it.

At 80C, you are still 20C off even thermal throttling the CPU using its built in protection!

Also, the core temp sensors are not accurate in these CPU's until they apprach 100C. They have a huge slope error, so 60C for instance may be 10C or more off the real temp but as you get to higher temps the reading gets more accurate until its pretty much spot on at 100C. The sensors only job is to throttle the CPU at 100C, so its best to view it as a countdown and keeping the countdown about 20-25C from 100C.

Having said all that with that cooler you will be fine on temps with a E7500. It produces much less heat than a Quad. The real killer is too much voltage. Just stick to 1.3v and under as mentioned above and you will fine. The max on Intel’s page is 1.36v!

Since it's a work machine however, I'd keep C1E and EIST (green functions) enabled and increase the FSB until you are happy with max temps and fan noise produced. You will need to up the voltage, by how much depends on your motherboard and voltage drop. Every motherboard will give different results, depending on the voltage regulators.
 
The last time I overclocked my c2q I used the Asus inbuilt probe software, that gave me heat and voltage readings.

Other than Prime 95, what other software do I need?

Voltage reading software & heat software & cpuz....

HWmonitor look like an all in one. All I need?

So you think I wont need to or shouldnt exceed 1.3volts?

Not to confuse maters, but my qx9650 is at 1.3725v for a 3.7Ghz stable oc. (Different ball game?)

Keeping to 1.3v what kind of speeds to you think I will be achieving as an overclock?

I can see on you tube loads of people are using this chip to play todays top games, so it must be pretty adequate to say the least!

With that cooler you can go higher if you want, but personally I don't like pushing past 1.3v max for 45nm. Many do however, going as high as 1.4v, and run fine, so its personal choice. For me 1.4v+ is heading towards degrading your CPU lifespan. As I said Intel's absolute max is 1.36v. It really does depend on the motherboard and how good its voltage regulation is so its hard to give advice. One premium motherboard may get 3.6Ghz out of 1.25v, with its stable voltage regulation, while another cheaper mATX board may require a setting of 1.35v. Also you have chipset voltage and termination (VTT) voltages coming into the equation too.

For a workstation, I wouldn't be bothered about extreme performance out of the chip. For this role, silence and power usage are more important than absolute performance and high voltage. So I would aim for 3.6Ghz and 333 bus as a max - it's a nice number! You should do that on a voltage below 1.3v with a E7500, but again depends on the board.

I run my E7200 overclcoked on my main Workstation, at 300FSB 2.85Ghz using default voltage (1.07v set by motherboard). I do it to keep power usage low as it's on 24/7 and at that speed it can do everything fine. That's actually undervolting, as the standard 45nm voltage is 1.225v but many motherboards set it lower depending on the chip used. Yet on my gaming rig I run a Q9450 at 3.4Ghz on a 425FSB at 1.20v, default set by the motherboard being 1.18v.. But I'm a wuss and don't push to the limit, just get what I need out of the system.

To answer your other question, HWmonitor is fine. Open hardware monitor seems better:

http://openhardwaremonitor.org/

Also grab CPU-Z, prime95 multicore version and realtemp. You should be then good to get cracking.

I always use the bios to overclock, don't like those software overclocking applications, but again that's personal preference.
 
My E7500 runs 24/7 at 3.8ghz just by upping the bus to 345 and the voltage to 1.36v with the temps maxed at 66ish under load.
It will run perfectly game stable at 4.0ghz with bus 363 & 1.40v and the temps max out at about 70/71 under prime95. I tend to leave it chugging along at 3.8ghz though.
I use a cheapo £15 Akasa cooler although I do have 7x120mm YateLoons helping out.

Good luck.

I've got to admit, this is probably the finest chip I have owned from a performance jump perspective. I came from an overclocked S939 San Diego 3700+ (which was a good chip) and was blown away by the performance increase.
I'll kind of miss it when I chuck a Q9650 in later this week. :(

 
Thanks for the info all of you.

Bit worried about going over 60c however.... even if the cpu can handle 70c safely, in my head 60c is hot!

This is just a work/office pc, so extreme speeds are not neccessary.

I need it to be safe to use even when the weather is 35c outside and im sweating my pants of in my loft (which gets hotter than outside in summer).

I think 3.6Ghz is a nice round number and should achieve all requirements - low volts, low heat but performance from the cpu.
 
Everything is up and running and the speed increase from the new chip compaired to my P4 is nice.

Two dissapointments however.

1. The mobo I purchased didnt have enough fan headers so I'v lost my front fan.

2. The Artic Freezer 2 I bought is absolutly awful! Horrendous mounting system.

At one point I was just going to leave it on with out properly fastening the cooler on to the mobo, but it came loose, when I started screwing the actual cooler on to the bracket.

Im sending it back for a refund, terrible cooler!

An absolutle nightmare.

What's wrong with the AF2 mounting system?
 
Awfull.

The pins are plastic pos, which get bent at an angle when you try to mount the bracket, add to that I couldnt push the pin that goes down the middle of it, becuase it was bent.

The cooler is probably very good, but the mounting pins and brackat are awful.

Sending it back for a refund.
 
Hmm, I never had an issue with mine which has been on and off at least half a dozen times! There are better coolers out there of course, but for the money it is bloody good!
