hey guys been trying to figure this out i have an msi a88x-g45 with a10 7850k wont go over 1.7Ghz regardless of what i do i called msi that was useless emailed amd useless as well please help unlock da power oh overclock gurus lol

Toggle the switch (Slow_Mode) located under the reset button to another position.

I was able to get my motherboard to stably (cross your fingers) run ddr3 at 2400Mhz.

I have an AMD A10 7850k on a Gigabyte GA-F2A88XM-D3H and the EVGA 2400Mhz 2x8 gb sticks and a 430W EVGA power supply.

SKU
898445
Mfr Part#
16G-D3-2400-MR
UPC
843368034054
I have the F9 Gigabyte bios.
Here's what I did:

1. LOWER the RAM voltage to EXACTLY 1.54V.

Most of the time, articles will tell you to set the voltage higher, but I found that mine works best at EXACTLY 1.54V. (ran Windows Memtest without any errors, played Metal Gear Solid V for two hours) The JEDEC spec says 1.65V, however, the computer would give a BSOD during any gaming if I had the Voltage higher than 1.54V.

At 1.55V, the over-power/over-heating issue would occur. But 1.54V seems to be the sweet spot to use this with the APU.

2.
INCREASE NB voltage by 0.018V.
INCREASE VCore Voltage by 0.018V.
Set Vcore Loadline Calibration to Extreme.
Set NBVID Loadline Calibration to Extreme also.


Initially, when I had the RAM at 1.54V, @ 2400Mhz without these increases, it would crash a game back to Windows. However, when I increased the NB and Core voltages, this seemed to cure the underpowering issue.

4. Automatically set the Timings. The RAM seems to work best at looser timings. The JEDEC spec suggests 11-13-13-35, but that never seemed to work for me. When I booted with AUTO settings, it chose looser settings and seemed to be fine: 11-16-16-42.


5. Disable X.M.P. and AMD profile.

6. Set RAM multiplier to 24.

7. Change some settings on the Core. I left the CPU clock at stock, enabled Cool and Quiet, and disabled most everthing else.

All other settings are at stock. I didn't change the NB frequency, it's at 1800Mhz.

Hopefully this will help someone who is having trouble overclocking the ram to 2400 with a similar set-up.

Saw some tech articles that suggest APUs when paired with higher end cards via Explicit Multi Adapter mode are able to perform better than the dGPU solo.

I was hesitant to buy into the hype of GCN and integrated iGPUs actually providing a benifit beyond low end graphics, but it appears to be a reality in software that codes properly for it.

I built a 7850k for my son almost 2 years ago now and if this proves to become mainstream and true it may just extend the life of his rig with dGPU upgrade for some time.

Look out for some Futuremark Time Spy benchmark results which test all that Dx12 stuff pretty thoroughly.

Ashes of the Singularity was supposed to make use of compliant iGPUs (GCN etc) in some beta or other, but I'm not sure we ever got to that point? It's about time if people are starting to actually use the iGPUs for low-latency compute functions.

Ok i have my sons 7850k machine for the week again to tune up and do some benchmarking. Here is the hardware im running on it atm.

7850k APU
8GB Gskill Trident X memory (stock 2400c10)
MSI A88XM Gaming Mobo (most current bios r1.7)

Im looking for info on some of the more obscure voltages as after reading through this thread multiple times some of you have had success playing with them.

I have never been able to get this 2400 speed memory stable at its stock settings. Barely even bootable when i try. Seems rock solid at 2133c9 though. Also highest NB clock i can achieve is 2000 before stability falls off a cliff.

Ill be doing what i can to maximize the memory bandwidth byvolaying with voltages again.

I may also pull my 390x out of my other rig and see how this APU holds up with EMA enabeled Vs my 8320e.

for what it's worth I have the same RAM on a Gigabyte A88X-UP4 and I could never get it stable at the rated timings either. I had to loosen the timings to keep the frequency stable. looser 2400 is ultimately better for the igpu than tigher 2133.
