AMD A10 7850K Low Performance?

[LWD Adnane]

Hello, I've tried looking for something similar to this post but couldn't find anything, so forgive me if there's already been a topic like this. I recently built a PC; AMD A10 7850K (Stock Cooler), 8GB ram 1600mhz, 1tb hard drive, windows 7 professional 64 bit. I mainly play Euro Truck Simulator 2, I've seen many people say (and watched videos) that the above APU runs ETS 2 really well, even on 1080p. Well for some reason I can't get good performance. Even at 4.0Ghz, my fps is still really poor. I play with settings high/medium, some specific things are set at low, and I still get about 33fps on country roads with resolution set at 1366x768, although my TV (which I use) can go up to 1080p. The issue isn't just with ETS 2, it's with all games. Sometimes the PC freezes, and I believe this may be connected to overheating. Could the heat also be ruining performance? I doubt so due to the fact that even if the PC has been off for some time, and the first thing I do on it is run ETS 2 the issue is still present. I have the latest version of Catalyst Control Centre if that helps.

Your RAM is too slow. The A10-7850K requires DDR3-2133 for the graphics to work well.

You could (depending on what RAM you got) try overclocking your RAM.

Have you been overclocking the CPU?
That would be the wrong way to go. Overclock the RAM and if you can get it to 2400 then maybe also overclock the GPU portion of the APu, not the CPU.

Thanks for the info, 8GB DDR3-2133Mhz RAM stick isn't too expensive so that should be fine, much appreciated.

Can you tell me what RAM you already have?
You may be able to overclock to 2133 without any problem. They often make 1333, 1600, 1866, 2133 all the same stuff but just with different settings so the lower stuff can be overclocked to the higher without a problem. At least on good gaming RAM with heatspreaders.

Also for the same price as a 2133 RAM kit you could get a R7 250 to do dual graphics hybrid crossfire with your A10-7850K integrated graphics. That will give it up to double the power though not all games will use it properly so it could sometimes be a little less.

Um I have a pair of RIPJAWS, 2 4gb sticks. As for the r7 250 I'm aware of that, planning on getting later on though. If you need any more information on the RAM direct me to how I find it and I'll be happy to provide. Thanks.

Install CPU-Z and run that; then go to Options > Validate > Submit Online
When your web browser opens with a unique URL for your CPUZ; copy & paste that here.
Then we can view your specs; such as the Motherboard, CPU, RAM and such...

There should be a sticker with the model number on one side of the physical sticks.

I believe that most G.Skill RIPJAWS DDR3-1600 should be safe for overclocking to 2133. It may require a voltage bump to 1.65V and will certainly require looser timings but the heat spreader should be able to handle the increased voltage.

Youd need to check your model number and a review of that exact series to make sure though. RAM reviews usually contain overclocking tests done by the reviewers. Overclocking can potentially break your stuff but done properly it should not though it may still wear it out sooner. Anyways it would beat replacing it right away if you could overclock it successfully instead.

Just buy a dedicated GPU; why all the talk of OC'ing the RAM? That's just non-sense, especially if the OP doesn't understand any of that.

[Rove]

Well I would suggest buying a R7 250 (or better) rather than buying new RAM for sure.

Overclocking the RAM is free though and it should be easy and safe if he can find his model number and use a review as a guide to setting up his overclock without trial and error.

If you can't find a review you can also try and match the voltage and timing of the same RAM from that batch that was instead set to 2133. It should look the same and be the same manufacturing run of that product line. Probably have similar model number also.

OP already has other possible issues; such as High CPU Temps; or maybe even poor PSU; why would u suggest to them to OC anything ROVE?

As far as DDR3 RAM goes; 1866 CAS8 1.5V is about the best sweet spot you'll find. Even 2133 or 2400 RAM won't be faster than that.

If he had 1866 CAS 8 I'd still suggest overclocking it to 2133 even at worse (higher) timings.

The APU needs the bandwidth, not just the latency. It does have cache for latency.

[_I_]

the amd apu has high latency cache too
its been proven that amd cpus like low lat vs high freq

You can test the AMD APUs with latency versus bandwidth and I'm pretty sure bandwidth wins.

I saw for example some guy with DDR3-1600 then overclock it to DDR3-2400 and get a huge bump in performance for doing that. Obviously since the latency remained the same or maybe even increased this was because of the bandwidth only.

I have not specifically seen tests with DDR3-2133 9,9,9,24 versus DDR3-2133 11,11,11,30 just to test the effects of latency on gaming and I would be interested to see any you can find.

Wow, thanks for all the assistance. At this current moment in time I do not have access to the internet on the PC, however when I do I will try all of the above methods. I'm likely to buy both a 8gb 2133mhz ram stick and a r7 250 gpu (as according to AMD that's the best one to use with the APU) before the end of the year, I appreciate all the help.

Do not buy a single stick of RAM.

You need 2 sticks for dual channel mode.

Do you have only 1 single 8GB stick right now?
That would be even worse than only having 1600 instead of 2133.
2 sticks run up to twice as fast for most things as only 1 stick would thanks to dual channel memory and the APU being able to use both sticks at full bandwidth at the same time thus doubling the bandwidth for most purposes.

I also still do suggest you overclock. I know your RAM should be able to hit 2133 pretty easy.
I know it should be able to hit at least 1866 maybe without increasing the timings and certainly without increasing the voltage. At 1.65V (if it was 1.5V RAM to begin with) it should be easy enough to hit 2133 and you might even get it to at 1.5V and a bit looser (higher) timings.

Since the overclock is free why not?

Also instead of getting the R7 250 + 8GB (2*4GB) DDR3-2133 for around $100~ to $120~ or so you could get a R7 260X and a new 500W PSU to run it. The R7 260X is better than the A10-7850K + R7 250 dual graphics just by itself. Also if you already have a 500W PSU you could stretch a little and get a R9 270 or R9 270X which would be even better than the R7 260X.

Thanks for that warning. At the moment I'm using 2 sticks of 4gb ram in dual channel mode, I guess this is what I'll do in the near future with the 2133mhz sticks. I will attempt to OC the RAM when I can, and if they hold for a long time I'll wait a little longer before I buy the 2133 sticks. Also I'm already using a 500w PSU, I'll do some more research on the R7 260X, and if it's as good as you say it may be a purchase. I think I'll leave the R9 graphic cards for the future, maybe mid 2016.
