Resolved Question

Can explain to me what PCIe speed 100mhz controls?

Mine is set to target speed 100mhz but it is reporting it at 0mhz. This may be a really dumb question but I can not wrap my head around what exactly this setting controls. I am wondering if it is for something I do not have or do not use (such as a SLI config or something)

My hardware -
asus m5a99fx pro r2.0 motherboard
AMD 8350fx cpu
Radeon R9 270x gpu
16gb ddr3 1600mhz ram
corsair 750w psu

Thanks for any replies.

I am starting to grasp what the setting is but now I am at a loss as to why mine is showing -

Target speed - 100 MHz
Current speed - 0.0 MHz

That can't be right. I am using AMD Overdrive. I am not trying to OC. I was just using the turbo setting and fan control when I noticed this. I wonder if it is not displaying the frequency because of the pcie slot I am using? I am not using the 1st slot on my mobo but it is still an x16 slot. Strange. Wish I was more of an expert when it comes to these things. Thanks for the link.

Many of the speed measurement systems

Are buggy so you know to ignore oddities like this. If you can't you contact the author of the app.

Second thing, remember that most PCs have POWER SAVING TRICKS so if the slot is empty or in a power save mode, current speed can be as shown.

Not much of a mystery after all.

My thinking as well, however...

When you've been having lots of PC problems and you are very suspicious of the motherboard already....these types of little quirks are simply hard to shrug off. If this was HWmonitor or something I would dismiss it without a second thought and would not have even made the post. I am aware of how buggy these types or programs are. I have a feeling there is a reason why this option is grayed out though. I will try to contact AMD. There is very little info about this that I can find anywhere.

The topic is not about motherboard problems.

You may want to start a discussion about those problems. Here we are chatting about 0MHz and how that might be just fine.

I really do not think there is anything terrible going on. I do, however, think there is a reason that the reading is not being displayed. It is not crucial right now though as I have a new GTX 1060 on the way. After installing everything to do with the new card I will check again. If there is still an issue I will probably make a new thread. Until then, thanks a bunch for all the timely replies. I see you answering a lot of threads around here. I hope you know that everyone appreciates it quite a bit.

Nice choice.

In reply to: Ok

I'm sure you'll like the 1060. And thanks for the nice comment.

Some mobo's specify that for best perf to use the pcie slot closest to the cpu.

Your mobo does not specify that but it might be best to move your gpu.

You are correct

In reply to: Slot

I does actually state just that in the mobo manual. When I first built the system (over 3 years ago) I originally had it placed in the 1st slot. My memory is not what it used to be but if I recall correctly the computer would not post until I moved it into the 3rd slot. I want to try putting it in the 1st slot again now. Is there anything I should do before moving it? Or will it be just fine? Thanks a bunch.

Not that I'm aware of but others may know of something.
