AMD A6-3650

post #1 of 10
Thread Starter 
I'm having an issue with overclocking. I bought a pc, didn't build it, the APU is 2.6ghz, with it's stock fan OC genie II could get it to 2.86Ghz, but when I tried to OC it myself I couldn't get it past 2.9Ghz without it hanging up. I went and got a Antec Kuhler H2O 620 CPU cooler and a Coolmax Zu-700b 700w PSU, thinking that would help, but it's exactly the same, nothing has changed except the temperature is significantly lower. OC genie still just puts it at 2.86Ghz, and I still can't get it past 2.9Ghz. I followed a guide, little by little I uped the CPU clock untill it hung at 2.9Ghz, then I uped the CPU voltage little by little, but it still hung up. I then saw that someone had the exact same APU and motherboard, and got it stable at 4.1Ghz, so I followed what they did, but nothing, still hangs up, any help would be appreciated.

dont use oc genie, just go into the normal bios and overclock that way. that would be my first thing to do...
also what is the motherboard, and who did you buy it from?

MSI A75MA-G55

It's a Cyberpowerpc GUA210

I did it through the BIOS too after OC genie didn't do what I wanted, same results, hangs up after 2.9Ghz

have you switched your moniter ports to dvi or hdmi?

Motherboard: MSi A75MA-G55
CPU: AMD A6-3650
RAM: G.Skill 2 x 8GB DDR3 1866
Power Supply: Coolmax ZU series 700w
Cooling: Antec Kuhler H20 620

Recently installed new RAM G.Skill 2 x 8GB DDR3 1866.

Everything feels exactly like I did before I bought new parts, except is quieter and runs cooler. Other than that I've noticed nothing different, not that it wasn't good to begin with, I just figured that I'd be able to play my games at higher settings, but they are still exactly the same. After spending all this money I'm getting pretty discouraged.

Overclocking is exactly the same, OC Genie II stays at 2.86GHz IF I keep the RAM at 1333, but I bought 1866 for a reason so if I leave it at 1866, OC Genie II won't boot up at all. So for now I have my RAM set at 1866 with stock CPU settings at 2.6GHz.

Manual overclocking is exactly the same as it was before. I followed a guide, which said up the CPU frequency little by little, saving and rebooting each time, untill it hangs, then up the voltage little by little, saving and booting each time, untill it doesn't hang anymore, then repeat with the CPU frequency, but after setting to 113, which makes it around 2.9somethingGHz, it won't boot up and I have to power it off and back on 3 times for the BIOS to reset. No matter what I choose as voltage, it's exactly the same, it won't boot back up past 113.

This motherboard makes a big deal about overclocking, that OC genie II "1 sec overclocking to 4GHz" and that it calculates what it can overclock to depending on your CPU frequency, DRAM frequency, DRAM voltage, but I've upgraded my RAM, PSU, and CPU cooler, it should be different than 2.86GHz, but it seems that 2860MHz is the only thing it OCs to, and I should be able to get past 112 manually, it should be different, but it's not, it's like there is a lock on it.

I dont thimk you can really overclock that apu. It is not the unlocked version. You need the A6 3670K apu to overclock well if im not mistaken. You have the locked version of the A6 apu.

Locked A6's can be pushed.... people are just lazy. In the early Llano release days there were CPU-Z validations of APUs being pushed into the 4Ghzs without the unlocked multi being posted.

 

Try to avoid the auto OC tools, they can be very finicky and often do worse than you (i.e. apply more voltage than necessary). And before you do anything, make SURE that the VRM heatsink is making GOOD contact with the VRMs. el gappo once reviewed this board and found the VRM heatsink mounting to be extremely poor.  The whole thing was mounted so poorly that it wasn't even touching the VRMs except on the sides.  This is an issue because it's a low end MSI setup. If you don't cool it properly then chances are you might face some really fiery problems by not keeping them cooled. The AM3 low end lineup was very prone to VRM failure.

 

Also, if you overclock and doing so bumps the RAM speed back down to 1333, then overclocking isn't worth it. 1333Mhz RAM will bottleneck an APU at stock speed.  Keep the RAM speed UP. If you can't do it, it's not worth overclocking the CPU/GPU as you may lose performance.

Hard drive needs to be in ide mode to get up above the 110ish area for the baseclock.
Ram/northbridge/gpu all get bumped the same amount with the baseclock, so you'll have to figure it out which one is causing your current issue. If it's not the HD, then its a good chance its the ram.
heres a baseclock to try if you are in ide mode

116 baseclock with the ram set to 1600 in bios = ~ 1866 ram and 3.03 ghz cpu

If you can't get much past that, loosen you ram timings 1 set (ie 9-9-9-26 goes to 10-10-10 30) and if it helps, keep going up.

I left OC Genie II off, left everything to auto and just changed the modifier to 30 making it 3GHz, and it boot up without any problems.

Edit: seems to be a fake 3.0GHz, windows says 3.0GHz, but CPU-z says it stays at 2595MHz
