Carrizo FX-8800P, A10-8700P Info and Optimizations - Page 26

post #251 of 314
It says "The following "Carrizo" series products are not supported with the AMD Radeon Software Crimson Edition 16.3.2 driver - FX-8800P, PRO A12-8800B, PRO A10-8700B, PRO A8-8600B, PRO A6-8500B, A10-8700P, A8-8600P and A6-8500P.", which is accurate. Last few releases were missing Carrizo support, but in 16.4.2 Carrizo is once more supported.

i was confused as well - i agree with nukedathlonman, when i first looked i thought that carrizo isn't supported in 16.4.2 but then i downloaded it and it installed perfectly on my fx-8800p laptop

since carrizo isn't even a year old, how many years do you think it will be supported? up until 2018?

I would be surprised if the driver support ends before the GCN3 (Tonga & Fiji) dGPUs. Probably closer to 2020 than 2018.

I looked at the page here: http://support.amd.com/en-us/kb-articles/Pages/AMD-Radeon-Software-Crimson-Edition-16.4.2.aspx

Quote: "The following "Carrizo" series products are not supported with the AMD Radeon Software Crimson Edition 16.4.2 driver - FX-8800P, PRO A12-8800B, PRO A10-8700B, PRO A8-8600B, PRO A6-8500B, A10-8700P, A8-8600P and A6-8500P."

The question was also asked on AMD's support forms - some sort of bug was detected by QA - Carrizo support was pulled for the time being.

Here: https://community.amd.com/message/2719694

Quote: "I think Mattamd said that they found some bug during QA and have temporarily held back support until the problem is resolved "

I tried to install manually (downloading and installing with the regular installer) - the installer would not update the video driver or anything else (though I'm using the A10-8700P, not the FX-8800P)

no way to modify the vbios somehow?

Depending on the game, at a gpu core frequency between 800 and 850MHz the throttling seems to stop completely. GPU maximum temp usually stays around 63-64 deg while the CPU reaches 58-59 deg (this after removing the dust filter from the air intakes and undervolting the processor to 1.2V). After long experiments and stress tests, I noticed that throttling usually occurs when the GPU temp reach 68°. It seems pretty low for today's standards, unless there is some other component (i.e. the switching regulators?) for which I don't have a temperature reading and that exceeds that value under load. It would make sense that lowering the frequencies has a beneficial effect on current draw too and, therefore, also on the power supply regulators.

As for TDP, I don't know how accurate HWinfo is, but with a 800MHz clock it reports a peak of 36W. I don't tend to trust too much these tools especially on notebooks which may have custom non standard, firmware and monitoring interfaces so take it with a pinch of salt.

I'm satisfied with the results. The machine stays cool, performance is decent for the price although it shouldn't befall on the users to do such fine tuning. The FX8800 built in GPU is reasonably fast for old (up to 2009-2010) games although having the ability to use a 1066MHz bus would have helped to squeeze out every bit of performance out of it. The M385X seems okay for modern games at low to medium settings which I guess it's okay for a laptop.

For fun, when I'll have some time, I'll try to run some benchmarks against a Macbook Pro I have at home with a Core i5 4255U cpu. This cpu has a TDP of 28W, and a Iris 5100 GPU. On paper the specs seems quite close to that of the FX8800P and the TDP is also close (the Intel CPU is made with the more advanced 22nm FinFet process).

My Y700 has some problem with GPU clocks - it goes down to 300MHZ every few seconds. HWInfo shows that the wattage is always under 38W and it happens even if I set clocks to such a level that the wattage is quite lower than 38W. Does it happen to you too?

the fx-8800p isn't supported in the latest 16.6.1 driver

anybody know which is the latest support driver?

there are quite a lot of upset customers trying to get answers as to why there haven't been any support for carrizo lately https://community.amd.com/thread/200614

1. You can update via the AMD software (Catalyst and Crimson) and it will update as much as it can
2. The FX-8800P is not fit for the 16.6.1, but the M385X is. Download the drivers, extract, and install it manually via the device manager

Hey everyone,
i recently got the Y700-15ACZ as well.

I simply installed the latest driver for the R7-IGPU (15.201.1301.1007 Beta (Crimson 15.12)) first, then i installed the latest driver for the R9 M385X (16.200.1025.0 Beta (Crimson 16.6.1)).
(€dit: Of couse i uninstalled the Lenovo Driver first with the AMD Clean Uninstall Utility)

Also the Lenovo branded Catalyst lack the overdrive option so I couldn't experiment with the GPU frequency to try limiting the throttling or to observe the effects on temperature and performance by lowering the clock. Today I'll try to enforce that from the BIOS (there is an option there) or I'll probably try the new Crimson drivers.

With this driver setup i can just go into "advanced radeon settings" and set for each application (or globally), on which GPU it should run.
It's actually possible to "over"clock the R9 M385X with Afterburner, you have to enable the inofficial OC-Limits and inofficial OC-Mode.

And you have to run an application which forces the R9 to turn on, otherwise you can't apply the settings.
However, it seems to be quite pointless, when i overclocked the VRAM to 1350MHz (from 1200), the GPU just stayed at 300MHz. Probably some aggressive settings from lenovo to stay within the power limit.
Of course overclocking the GPU in a laptop isn't a great idea anyways.
But maybe someone with more experience can make use of that.

I made a script for AMDMsrTweaker to lock the CPU, so it wont clock below 2,1 GHz (that's the highest possible *non-turbo* Clock)
While gaming, the Cores sometimes usually clock down to 1,4GHz for half a second or so, with this script it will only go to 2,1GHz.

I didn't do much testing yet, so i can't tell you if it will actually improve Framerates or if it's a good idea in general though.
Code:
start C:\xxx\AmdMsrTweaker_1.1\x64\nowindow.exe AmdMsrTweaker.exe P0=34@0.875 P1=32@0.75 P2=29@0.75 P3=25@0.5 P4=23@0.4 P5=21@0.325 P6=21@0.325 P7=21@0.325 APM=1 Turbo=1
exit

btw.: The "real" Voltages for Carrizo in AMDMsrTweaker seem to be 0.775 + ("Voltage in Script"/2).
Unfortunately, it doesn't allow me to apply any voltages under 0.775V, which would be nice for adding a low-power-state for idling.

Has anyone tried to undervolt the NB yet?
I tried it, but it's really hard to find the "real" voltages since AMDMsrTweaker unfortunately doesn't fully support Carrizo.
So after a few crashes i gave up.
Is it worth it after all, how much power does the NB usually draw under full load?

I'm using this tool and it works, but when the when running heavy games, it will throttle to 2.1GHZ no matter what
