[SOLVED] Q9500 on Nec PowerMate ML470

[Thanos_D]

Hi, so, recently I got my hands on a Nec PowerMate ML470, with an MSI MS-7377 motherboard and Q35 chipset. My question is: will an Q9500 work on this board? I have seen listings of this pc with an Q6600, but not anything higher.

So I found some listings of this system with a q9400 in it:
https://www.userbenchmark.com/System/NEC-POWERMATE-ML470/117646

Now, the bios will also have to support it, but I think that would mean any of the q9xxx or q8xxx series would work ime.

Definitely try it out and let us know!

Thanks a lot for answering. I found this page, which lists the Q35 compatible CPUs, and while it includes the q9400 and q6600, it does not list the q9500, but lists the q9550 and q9550s. Could that be an indication? This site has a manual of the motherboard, and it mentions that it supports Yorkfield Quad Cores in general.

The problem is that compatibility is not only dependent on the chipset, but also the bios. Generally I've found that if any q9xxx is supported, all of them are and even the q8xxx will be supported.

Ok then, I will order an Q9500. Thank you a lot for your help

Good luck! And make sure you're getting a genuine used chip and not some fake from the land of the virus. I wouldn't trust those fake chips, no matter what the price as they can have issues.

Update: The Q9500 is working perfectly fine, and with very reasonable temps, 65°C on one core, and a bit lower on the others (under stress test after an hour and a half running it) and not with much noise.

That is running hot, probably due to an aluminum heatsink designed for 65w.

There's a couple of different solutions to this. One is to simply make the fan spin faster so there is more airflow. This would bring temps down to at least 40c if not <40c. Then it would only hit 65c under a full stress test. To do this, there may be an option in the bios to control fan speeds.

Otherwise, you can simply pull the pwm pin on the fan connector. It is usually blue, and with the aid of a pin or thin blade you can press the tab in the back of the plug that holds the wire in and just pull it out. If you manage this you can easily just push it back in if you ever needed to reverse the mod. Be sure to take that pin and seal it in some tape so that it doesn't touch something and short it out though. This is actually what I do to my systems with a 65w heatsink since I'm not near them. They will run 40c in an 80f room and when stressed they would climb to high 60c, but would immediately start to cool off once the stress is removed indicating that the heatsink wasn't completely heatsoaked. I would expect you to have the same results. Depending on how load the fan is at 100%, you may hear a lot more noise or only some more.

Another thing to do would be to swap the existing fan for one that pushes more air at the same rpm. This will take some research for sure, but might be the best overall solution.

The problem with this type of heat is that the motherboard was never designed for it, so over time it will cook some of the components. And especially with the age of the system, these components are already old so just a little bit of stress may make them pop.

My bad, I forgot to clarify, those temps are under stress test, and after running the stress test for an hour and a half. On idle it sits at the high 30s

orderd cpus from china many times without any problems. never had any problem ordering from aliexpress no fake chips.
