Liquid Nitrogen is for beginners, but a good start. Break out the Liquid Helium and get to 9 GHz. The FX-Series has no cold bug as far as i know, because of its Silicon on Insulator fabrication technique. Record of the FX is 8794.33, but it is likely you need a stonger PSU :D
Yeah I'm happy with 24/7 use, I may revisit my OC with custom loop.

Can you check the power draw at the wall of this PC? And can you check how warm your VRMs are under load? Hardware Monitor from CPUID.com might give reliable temps, because it is a Gigabyte board.

Biostar is Gigabyte?

its for the fun, not the performance of the FX chip, guy want's to OC the FX 4350 and see what he can do with it, an i5 2400 wouldnt be nearly as much fun either, it's not all about the performance as much as pushing a chip as far as it can go.
I can relate, I've honestly become quite bored of the 2400-2500

Oops, my bad. Someone was talking about a Gigabyte board. You have a Biostar board, that is different. But you can still give it a try, and see if the temps are more or less in the range where they should be.
So Gigabyte is not Biostar :D

Mhh, 21°C at idle and nearly 50°C at load. Does not seem correct to me. Do you have you AC running at 15°C (60F)?
Maybe you need to check you "Idle" temp in the Bios. But keep in mind that the CPU runs at full speed (not load) in the Bios.

AMD is not known for accurate temp sensors... at least, not at idle.

Increased core voltage slightly. Temps are 70*F at idle and 120*F under load.

Mhh, 21°C at idle and nearly 50°C at load. Does not seem correct to me. Do you have you AC running at 15°C (60F)?

Hold on, my cpu idle is 43, gaming it is 55. Ryzen blender takes it up to 70-77.

Your WC should be out performing my Ashura, especially with 4 cores

I just hooked up my FX 8370. It is running on an Asus M5A99X EVO R2.0 board. Only stock for now.

When i run Prime 95, Hardware Monitor says 40°C (104°F) on the Package (CPU sensor) and 59°C (138°F) on the CPU-Sensor of the Mainboard. I think the Mainboad one is correct.

AMD Overdrive even says 29°C (84°F). Which i consider plain out wrong.

Voltage at 4GHz is 1.334V it seems.

What are you using for cooling?

Temps are much better with fans on a higher speed setting (still not annoyingly loud which is good)

Now when I tax the CPU it stays under 100*F for the most part.
That's good :D

Well both temps are correct. One sensor is on die the other is on mainboard PCB. Cooling the backside of the mainboard PCB should help bring both temps down.

That chip will do a decent 4.6-4.8ghz on that cooler I'd bet. See what you can cool between 1.4 and 1.45v and bump the multiplier and test.

Oh and AMD overdrive tells you offset to throttle voltage I believe is 70c. So 40 + 29c would be a correct reading from AMD overdrive. It was in fact when testing factory stock settings and AOD reaches a temp of 65c you'd see the FX processor throttle. A manual mode overclock shuts this feature off. I only tested with Asus motherboards however.

Well here is my best effort for tonight. I'll be back at it tomorrow afternoon!

Fab and Glam!! Nice clocks Storm.

You are right ShrimpBrime. AMD overdrive gives the Thermal Margin.
So, you think the 40°C are correct on the CPU. But the 60°C is close to the cpu and i think to the VRMs as well. And it ends up hotter then the CPU itself?

And when AMD overdrive says 1.334V on the CPU and CPU-Z says 1.26V, which one is correct? In the Bios it says 1.33V


Well done storm-chaser :)

Not a bad deal for an fx4xxx . I think I paid $45 for a 4300 on eBay a few years ago, it came wrapped in foam lol. I actually bought an 8350 bnib and they sent me two !! Depending on what you do, fx is a great budget choice. I still have a couple fx systems with 8350s , one has a 1060 and the other a 980.theyre still really fun to play on. With good cooling you should be able to hit some high over clocks . Those 4xxx run really cool
