Hi I recently just bought a AMD-FX8320 Black Edition and i had problem overclocking with it...
May i ask help from anyone here? Here are my computer Specs...
CPU:AMD-FX8320 Vishera 3.5GHz Black Edition
GPU:Sapphire HD7850 2GB OC version
Motherboard: ASRock 970 Extreme3 R2.0
RAM:1x8GB Kingston 1600MHz Desktop RAM(not HyperX or any of those High performance RAM,just a normal RAM)
Power Supply Unit(PSU):AVF Extreme Power 650W
HDD:Western Digital 1TB
Here are my problems...
1)i intend to overclock my CPU to 4.5GHz when i just bought it. I downloaded the AMD Overdrive and let it Auto tune and it achieves only up to 4.4GHz and with 1475v CPU voltage and 1.375v NB voltage...when i hit apply it turn into blue screen...So i intend to go BIOS to overclock myself...some professional told me most people overclocked succesfully by lowering the Multiplier and Boost up the CPU frequency...I tried it at CPU Frequency 250 and multiplier 18x with 1.45V and it cant even load into the BIOS...I had to Clear the CMOS to save it...Now i intend to do it with 220 and 20.5x with the same voltage...It went into the OS sucessfully...But crashed after about 5 minutes even i didn't open any program or games in the OS...i tried it again after a few times with lowering the multiplier to 20x and become 4.4GHz and also the same problem...Can anyone tell me what should i do? Or can anyone give me their result of stable overclocking with the same specs as me?
2)Now i had choose to put my CPU frequency at 210 and Multiplier at 20x with 1.4V CPU voltage and become 4.2 GHz(seems to be OK...) However when i run the stability test using the AMD overdrive...OMG. I set the time limit as 10 minute...It showed there Stability Test active at 19:38:55...I was praying to God all the time...However it goddamn stopped at 19:47:38...showing that Hardware failure detected...What is that??How can i overcome these problems? Please clear my doubts...Thank you Much Appreciated
Here is a pretty good walk-through video when it comes to overclocking an AMD rig: https://www.youtube.com/watch?v=MckeAmnDeTk
As an addendum: take it slow and easy. Finding a good stable overclock can easily take hours, and for eking the most out of system can take days.
A couple notes: Your motherboard, while capable of overclocking, isn't the best choice for it. 4.2ghz might be the upper limits it can handle. Additionally, I don't know how good of quality AVF is when it comes to making PSUs. If it is not giving the amount of power the CPU desires, that can be an issue. Building from that issue, there is the matter of Load Line Calibration (LLC). With *any* PSU, whenever the CPU is under load and draws more power, some of the energy as it becomes vibration and heat - LLC feeds extra power to the CPU to make up for this loss.
I would also try switching to CPU Multiplier overclocking, instead of Front-Side Bus (FSB) Overclocking. If your RAM is basic stuff, and doesn't have heatspreaders, it won't behave too well to being overclocked. Sometimes, you have to pay close attention to the other numbers affected as well, and keep them close to stock. Utilizing a CPU Multiplier overclocking side-steps all of that, although you are only increasing your processor performance, not the performance most of your rig.
Anyway. I just vomitted out a lot of stuff, and it is a lot of process. Watch the video, take it easy and slow, and perhaps start from scratch. If done properly, you won't have to worry about BSOD, just failed Prime95 runs.
EDIT: I just realized that you didn't mention what cooling solution you were using. It is not the stock cooling, is it?
^ tried using that guide earlier. Had to have pretty high voltages (and temps) to get a decent OC. It seems as though OCing from the multiplier works better for me. Although I'm not the OP I am having an issue whereby I cannot use AMD Cool'n'Quiet or C1E when using manual voltages, only offset. Any ideas?
That's what I get for making posts before work and in a hurry.
Even though I had linked the walkthough video, I had also said to try sticking to only multiplier-style overclocking, so when I read those two statements, I took it at meaning that it was not a good guide. That said, in my mind, you requiring such a high voltage to obtain increased gains was a product of (bad) luck-of-the-draw silicon, not an attempt at "mixed" overclocking, which is probably what you actually meant.
That said, I know Offset, as opposed to manual, is considered a more advanced way of overclocking, and helps with heat and power in light-loads and idling, but I am not sure how it differs in its ultimate goal of providing energy to facilitate CPU frequencies?
