Asrock P67 Extreme4 review

@ radier

Your suggestion works, thank you so much! I'm now able to see the chip running at full speed during LinX and Prime95. I set it to 200/200/200 and I have NO idea what i means. If someone can explain how the logic works, it'll be great.

[radier]

I have explained it to you few posts above. Try to read some of the reviews about Sandy Bridge especially the part about Turbo 2.0 technology. For e.g. http://www.tomshardware.com/reviews/...0k,2833-3.html

Default settings for Turbo Power Limits are:
Short 150W
Long 95W

Now keep in mind that default TDP (Thermal Desing Power) for 2500K/2600K is 95W at default clock speed. If you want to OC for lets just say 4,5GHz on all 4 cores during stress you will find out that this 95W is just not enough as the TDP rise up with the frequency and vCore. So this is the part where you adjust UEFi settings to 200/200 (for Short and Long) to prevent CPU throttling down.


I hope this is clear for you now.

Thanks and I'm clearer now. Looks like we can now control the TDP through UEFI which is a big improvement compared to previous CPU generations. Now it makes sense as to why increasing the TDP will help to make the chip stay at that speed. Btw in your sig, it says 5Ghz @ 1.328V. Is that LinX or Prime stable? That's one heck of a chip you've got there Mine can only do 4.6Ghz with the same voltage.

It is LinX/Prime95 Blend/IBT stable. I was lucky one with Batch I've recived (L041C124), which is the best around for 2500K.

Yea, you git I paid a premium for my 2500k (got it in the first wave) and with some good cooling best my chip does is 4.8GHz. I blame it all on one core with my 2500k thats 6c hotter at idle than the next hottest core and 9-10c hotter at full load than the next hottest core. My guess is its probably TIM used under the IHS and not solder, but even I'm not eager to go poking my 2500k about with a knife until I know for certain.

The USB 3.0 port of the Asrock P67 Extreme4 doesn't work with a wide range of USB devices like:
some USB2 modems, USB2 TV tuners, some USB2 memory sticks, some USB 3.0 HDDs.

While the Etron chip is touted "the world’s fastest USB 3.0 controller and the first to be interoperable with USB 2.0 and 1.1", the fact is that from 10 USB devices which I own, only 3 are working properly with my Asrock P67 Extreme4 motherboard's USB 3.0 ports.
At the same time all of these devices work correctly with my laptop which is equipped with the NEC USB 3.0 host controller.

I have an USB 3.0 HDD which is getting disconnected while copying large files, thus corrupting my data.
I have an USB 2.0 memory stick which is seen sometimes as unformatted on the USB 3.0 port, sometimes is seen correctly.
I can't use my USB TV tuners at all on the USB 3.0 ports of this motherboard.
Installing a Logitech Quickcam Pro 4000 into the USB 3.0 port causes BSOD. (This last info is from an other owner.)


I wouldn't recommend this motherboard to those who need the USB 3.0 port functionality.

If you can give me a list of the USB2 and USB3 devices that caused the BSOD I may be able to push something through with Asrock.

Not working at all
Huawei E1750 USB modem
Technotrend S2-3600 satellite TV tuner
Technotrend S2-3650 satellite TV tuner
Technotrend S2-2400 satellite TV tuner
Nokia E52 phone (USB connection)

No BSOD, they just don't work at all.

Working with issues
Silicon Power Armor A80 USB 3.0 HDD (with JMicron JM539 chip)
Kingston DT 100 G2 USB 2.0 32 GB stick

Working
Western Digital Passport 500 GB USB 2.0 HDD
Western Digital Passport Essential 500 GB USB 2.0 HDD
Kingston DataTraveler USB 2.0 16 GB stick

Did you enable Legacy for USB 3.0 ?

Thanks for this, if you come across anymore devices send me a PM. Once I have a list with more devices I'll forward it to Asrock so they have something to really get their teeth into.

Did you enable Legacy for USB 3.0 ?

I have legacy USB3 enabled in the UEFI, BSOD with Quickcam Pro 4000.

Did you enable Legacy for USB 3.0 ?

Yes. Legacy USB 3.0 is enabled.
