So I put a support ticket in to AMD because they still don't have updated drivers for their 990fx chipset and Windows 8.1. Most everything works fine, but if I let my computer sleep, I lose my overclock settings. Obviously not a big deal because I simply don't let my computer sleep. But I had to share this response because quite frankly, it's pretty sad.
My Initial ticket: "I noticed that Windows 8.1 doesn't support the sleep feature properly for the 990FX chipset. Particularly if you overclock your CPU, if you put your computer to sleep, it will wake up at a certain frequency. In my case, I have my chip, the 8350, set to 4.5 ghz in the bios, but if I let my computer go to sleep, it will wake up at 4.1. This doesn't seem to matter what I set my clock speed to either. I did talk to Asus (Crosshair V Formula-Z) about this but they said all their drivers have to come from AMD. I didn't know if you had a driver in the works for 8.1 but I thought it wouldn't hurt to ask. I've had an overclock specialist named John at Asus confirm this on his end, but overall, it's not a big deal because as long as I don't let my computer go to sleep, it runs fine. Thanks for the help and I hope you have a great weekend."
First AMD Responce: "We apologize for the delay. Your e-mail was misplaced by our server and was only now reclaimed and sent to the Global Customer Care team. We are very sorry for the lack of response and extended wait time in dealing with your request.
I understand that you have trouble in the FX-8350 wakes up in a lower speed than pre-set. If this is incorrect, please let me know as the information provided may change.
There is not specific CPU driver of FX-8350 for Windows 8.1. Please note that the default clock for FX-8350 is 4.0GHz and the processor has a Turbo core technology to boost 4 cores out of the 8 to 4.1GHz. The Turbo technology will automatically change the frequency to 4.1GHz with 4 cores when it detects the system is idle. As such, this might be the reason you are getting 4.1 GHz after the wake up. AMD does not support any setting out of our stated specification including the setting to 4.5GHz. A workaround would be to disable to Turbo core technology in BIOS but if there is no such option available, you may proceed to use the processor at its default frequency.
In order to update this service request, please respond, leaving the service request reference intact."
My Responce: "Sorry for a late reply on this, I've been sick. Yes, I definitely have the ability to disable turbo core. It's disabled. And this doesn't have anything to do with the CPU but the chipset. Windows 7 doesn't have this problem because there was chipset drivers made for that OS. Windows 8 also had the chipset drivers. What I want to know is, does AMD have any plans to make an updated Windows 8.1 chipset driver for the 990fx chipset they designed, or are they just cancelling the 990fx support for financial or other reasons? This is important because any customers using what is currently the AMD high end right now deserve to have something fully functional with the latest OS. I understand that AMD might not support overclocking, but if that was totally true, they wouldn't unlock the cores of their chips for enthusiasts so that they can make world overclocking records. They may not warranty overclocking, but they support it to the extent they design toward it.
The simple fact is, a computer should be able to go to sleep and wake up with the same clock settings. Bios's today are designed to give control to the OS after boot, so without a driver, the OS doesn't know how to wake properly once it has control, hence the reason for asking about drivers, since none exist for 8.1.
I'm a very active member as well as a news hound for a hardware website and while I won't write articles about this, I would feel obligated to share that AMD not treating their customers well in regards to this matter as well as not showing the attention to detail that Intel shows. Finally, I went through support with several other people and we know this is a simple driver issue. I understand that making a new driver may not be simple, particularly with 8.1, but this can't be blamed on the CPU or the OS. I'm not upset as this isn't serious. I just like to let my computer auto-sleep after 30 minutes. I can't with an overclock and even at stock, the voltage regulation drops significantly lowering clock speeds below the 4.0 minimum the fx-8350 should be at.
If there is no intention of a driver being updated for the later AMD chipsets and Windows 8.1, I'd appreciate just knowing, and being told truthfully that this is the case. Even though I'd be slightly disappointed, I'd feel that was more honorable than trying to blame other issues. Please let me know if it's not too much trouble one way or another and have a great weekend."
AMD Final Reply: "Dear Joshua,Thanks for your reply.
Regretfully, we cannot comment on whether the Windows 8.1 chipest drivers for 990FX will be released in future, but we will report this to related team and please check the following site for most updated chipset drivers."
Maybe something will come from this if it's reported.
