rx 460 GPU preventing a CPU overclock

[Fire Lantern]

Hello!
I'm trying to overclock a Xeon e5450 and the chip itself is overclocking really well, but I'm running into a problem when I pair it with an RX 460 on the mobo any sort of overclock on the CPU causes the system to give me a GPU error beep code. Does anyone have a clue as to why this could be happening?

Here are my computer specs:

Motherboard: Gigabyte P31-ES3G (Socket 775)

CPU: Xeon E5450

GPU: Sapphire RX 460 Single Fan OC

RAM: 2x2GB 800MHz

I'm almost certain that the PSU is the issue here.

How come tho? I can swap out the GPU for another PCIe exlusive GPU and it works normally. I've also just edited in the correct PSU as I too was under the assumption that the psu was the problem and bought a more reliable one.

Oh maybe it isn't then, sorry.

Heck, well if I won't be able to get any answers I guess I'll have to replace the GPU.

Have the same problem with my e5430 and a GT1030 on a G31M-S2L mobo and the problem is the GPU. When I swapped the gpu I could normally overclock, but ofc I'd like to stick to my GT1030 rather than my weaker gpu  

Also posted the same problem but to this day no solution for it

Hey, I don't know about the GT 1030 but I came down to the conclusion that it has something to do with legacy bios. In theory an RX 460 apparenlty does not support legacy bios and I don't think that 10XX does either so overclocking the CPU might somehow make the GPU not recognise the bios or something. I have no clue why. I sold the 460 and am going for an aftermarket 7870 which sadly draws more power but should be about the same (a bit better) performance.
I know that Nvidia 9XX GPUs do support legacy bios fully so it might be worth going there and doing a refund on the card if possible.

Sorry for the late reply but maybe that's the issue. Thanks!

I have some more info that might be useful. For some reason an undervolt and a slight OC helped but it might be that this is not it because I used a 750ti with the mobo which is clearly supports legacy BIOS and the regular higher voltage + OC did not help.
