Random freezing, apps closing and BSODs with AMD 8300

chuchinsito · Jun 7, 2017

Hello,

I found a FX 8300 at a bargain price, and seems like a nice upgrade to my older Phenom II 965.
Before using the 8300, the Phenom II was @ 3.8 GHz stable.

Since I read that FX 83xx are virtually the same chips, I tried to boost the FX 8300 to 4.0 GHz, like a 8350. But I can't even hit 3.7 Ghz without hitting BSODs and freezes.

This is what I do: first, I disabled Turbo Core and anything power saving related in the mobo, and change the multiplier, in small steps until I hit 3800. I bumped the VCore to 1.35V, but no cigar.

At first, Prime95 worked ok for around five hours, but after popping a game, it keep crashing.

Here are my specs:

■ AMD Fx 8300
■ Asus 1050ti Dual Bearing
■ Gigabyte GA-970A-D3 rev 1.3
■ 8 Gb 1333 Mhz RAM
■ XFX 500W Bronze 80 PSU

I know my rig isn't the best to make OC, but it baffles me that I can't even get the same speed with this CPU. Am I doing something wrong? And, if I got a 8350, that means my system could be inestable as it is now?

Apologies for bad english.

Update (Title changed): I can't use the chip even at stock voltages and speeds. Random freezing and apps crashing occurs often. I don't think it's my Power supply since my last setup used more power and still run without inconvenience. I have ran a Memtest86+ test, changed RAM slots, seems ok. Temperatures are fine, near 45°C running Prime95, but crashing. Disabling two cores didn't work either.

How possible is that I got a bad CPU?

You can go higher on the vcore if you want. That is probably the first hurdle. Not enough voltage. AMD suggests 1.5V as the safe max. Many go higher than that.
What gfx card do you have? Your 500W PSU may be near its limit for providing clean power. If P95 holds steady for 5 hours, that indicates a possible voltage drop, spike, ripple, etc when the gfx card is added to the mix.

chuchinsito · Jun 7, 2017

Current gfx card is 1050ti. Before that, I could achieve overclock with the Phenom II 945 paired with an AMD 6870, which uses more power than the 1050ti (75W vs 150W, according to what I saw in specs). Maybe it affects that the new gfx card doesn't need external supply, I don't know.

I will try higher vcore and post results. Right now I left the computer at home running Prime95. Hope the PSU doesn't explode lol.

clutchc · Jun 7, 2017

OK. The 1050 Ti wouldn't put an undue amount of extra load on the PSU, so I guess we can eliminate that. But yes, try some more voltage. My FX-8350 needed 1.425V to get the 700 MHz increase. (Asrock 990FX Extreme6 board)

chuchinsito · Jun 8, 2017

Well, I came back with results. Seems that the systems chokes even with stock clock with turbo active. Reading on olders posts on this forum, the motherboard I have doesn't support 125W Bulldozers, so I think I shouldn't try to get the same perfomance as a 8350.

Unless someone here says he can overclock with the same Mobo + CPU as mine, right now seems impossible. Time to save for Zen.

chuchinsito :

That board should support 125W CPUs like the FX-8350 just fine: http://www.gigabyte.us/Motherboard/GA-970A-UD3-rev-30#support-cpu
But if it chokes with everything set to default, there must be some other hidden issue. What happens exactly when the board is set back to default?

chuchinsito · Jun 8, 2017

clutchc :

Back to defaults, works well. Take in note that mi Mobo is rev 1.3, and it doesn't support any 125W Vishera CPUs: http://es.gigabyte.com/products/page/mb/ga-970a-d3rev_13#support-cpu (strange, Google finds the page in Gigabyte US but it's 404). It doesn't list the 8350 or 8320, for example.

I still have a Phenom 965, and I could overclock it to 4.0 Ghz before, with a slight vcore bump. Maybe I should try it again to discard a faulty PSU.

clutchc · Jun 8, 2017

Ah. I see. But at the opening post, you listed your board as Gigabyte GA-970A-UD3 rev 1.3, not GA-970A-D3 (rev. 1.3)
If you do indeed have the latter, that could well be the issue.

chuchinsito · Jun 9, 2017

Yes, I got confused. Since this motherboard can't handle any Vishera above 95W, I think it's unsafe to Overclock. I will stay in the stock until I upgrade. Thank your for your help, clutchc.

chuchinsito · Jun 12, 2017

Well, seems that I got a failing hardware. The system isn't stable even on stock configuration. One weird thing if that if I put the CPU coltage in auto, it's set to 1.4125 volts, I think it's way too high for stock speed (3.2 Ghz).

Freezes seems to happens at random times, sometimes I can play for a couple of hours without problems, another time I'm just browsing and I got a freeze. It freezes everything, even mouse and keyboard, no bsod, nothing. Only a reboot help.

I have seem other threads about this problems and it's seems they also don't find the cause. I feel that it's a mobo a problem, that's suck since it was a budget upgrade until Ryzen.

Have you eliminated software conflicts? Run CCleaner and do the Clean and Registry portions both: https://www.piriform.com/ccleaner
How about Malware? https://www.malwarebytes.com/

Might also be a bad memory stick causing the freeze. Run memtest on each stick INDIVIDUALLY in the first memory slot. http://www.memtest86.com/

chuchinsito · Jun 13, 2017

Hello again clutchc, thanks for keeping up.

I ran memtest86+ last night, the memory passed all the tests for about 4 hours each. I will check into software conflicts then.
Also, I will put again the old Phenom CPU in the PC today, to see how it works.

This page describes almost perfectly my issues with the system: https://blog.davekoelmeyer.co.nz/2012/11/01/system-hard-freezes-with-the-amd-fx-8350/

clutchc · Jun 13, 2017

Yes, if the board is unsuitable for 125W CPUs, then that is always a possibility. The link you sent shows it is not suitable.

But this chart shows that the board is indeed suitable; for up to 140W CPUs in fact. https://docs.google.com/spreadsheets/d/1a8k1fAzGnSNQGsMJi4Rl22RRdG_4ni98heLTM_SxNGQ/pub?gid=3
I wonder if there is a difference in that board sold in the US and where you are?

chuchinsito · Jun 13, 2017

Well, the board was bought in Mexico, so that can be a possibility.

Right now I popped back the AMD 965 and I'm running an stability test @ stock speeds.

I noted that the motherboard on, auto everything, clean CMOS, sets a high CPU Vcore to both processors. 1.4125 for the FX 8300 and 1.475 for the 965. Aren't those too high for running stock? I have a 212+ for cooling.

These are my current temps and loads, running Prime95 for around an hour: http://imgur.com/a/3gLZA . Will report back in a couple of hours more if the test fails.

chuchinsito · Jun 14, 2017

Prime95 failed @ stock speeds with the AMD 965. Memtest86+ didn't find anything on the two sticks, one by one. I'm leaning more towards a PSU fail, since the 965 consumes less power than the hungry 8300. If the systems fails today in a gaming session I will wipe the HDD.

clutchc · Jun 14, 2017

It depends on which Phenom II X4 965 you have. They can be 125W or 140W. Whereas the FX-8300 is listed as a 95W CPU if you haven't OC'ed.
The 965's voltage is within reason considering all 4 cores were at 100% usage. I have my 965BE @ 4.1 GHz and its vcore is at 4.125. But it depends on the board and its components.
The strange thing is that the 125W 965 runs fine, but the 95W 8300 chokes.
Did you run CCleaner?

chuchinsito · Jun 16, 2017

Yeah, I ran it. When I worked with the AMD 965 back, the PC ran fine, no issues, Prime95 worked for about an hour. A friend lend me a PSU and same results. So it's the MoBo or the CPU.

Since I don't have spare hardware, I wil check with the store if the CPU is defective.

An FX 8300 is the same silicon as a FX 8350, but they are of different bin and therefore are not expected to work at same voltages and same clocks. If it did the FX 8300 would be a FX 8350.

You will need more voltage. Push it up to 1.45V for 4.0 GHz

My rig running an FX 4350 needed 1.506V to hit 4.6 GHz, ~1.6V+ for 4.9 GHz in sig.

Prime95 for 5 hours is not enough. You either do 24h of Prime95 blend, or if you have less time, 20 runs of IBT 2.54 AVX at High setting.

Contrary to popular belief, most of the FX 83xx to FX 8350/8370 clocks on stock voltage is very unstable, only stable enough for validation. In real life FX 8300 is AMD's lowest CPU bin, and will need more Voltage/Power to hit higher clocks.

Good luck, and dont exceed 1.55V in the quest for 4.0+GHz!

chuchinsito · Jul 17, 2017

Thanks for the suggestion!

If anyone is interested to know what happened, I sent the CPU back to the store and they indeed found the same problems, so I'm getting a refund in store credit.

Since they don't have FX anymore I think I will update to Ryzen.

Cheers!

What about the DDR3 RAM and board? You need a AM4 board and DDR4 RAM for Ryzen. Anyways, good call, IPC is much better for Ryzen.
