Motherboard failing ?

[davidgarceau16]

Hello everyone,

I need some help now as I have been suspecting a motherboard failure for quite some time but I just would like to get a second opinion from some of yous.

SPECS
MOBO : Gigabyte Ga970a DS3P Rev 2.0
CPU : FX 8370 downclocked @ 3.2 Ghz 1.32v (stock is 1.3875) (I will explain why down here)
CPU Cooler : H100i v2
GPU : GTX 950 EVGA SC+ clocked @ stock
RAM : G.Skill Ripjaws DDR3 1866 4GB x 2 clocked @ 1600 (I will explain why down here)
PSU : EVGA 750 G3 (BRAND NEW)
CASE : Thermaltake View 31 RGB (BRAND NEW, not that it matters)


So this build is 2 years old and I've been having some issues the moment I switched my Phantom II x4 925 to the FX about a year ago. At the time I had a Gemini M4 (I know....) as a cooler and my temps reached 65 under heavy load. No problems other than that yet, so then I decided to switch to a h100i v2 and to the view 31 case.

I want to state that before I started testing, I checked everything I could for HDD or RAM failure but they all passed. So these aren't the culprits AND I KNOW MY MOBO ISN'T 8+2 PHASE !

Then I started having problems with booting, pc was booting twice and sometimes 3 times before it could post and go on. I concluded with some testing that it was the Core Boost, I fixed it by changing CPB's speed lower than the normal speed. Fixed

All the while i was fixing this I started having random hangs, sometimes the HDD light would be on, but not every time. Keyboard and mouse unresponsive naturally. So i looked up if my VRMS were failing on me.

Seems like they were so I decided hey , what if Iower my core counts, my vrms are gonna accept a 4 core cpu right ? But the freezing kept going, so here I am, with RAM at 1600 cause it was causing instability and my CPU at 3.2(8 cores) and vcore at 1.30(Stable) I haven't had a single freeze for about 2 weeks.

What do you guys think ?

Also, CPU TEMPS arent't the problem CPU is about 40 under load even at 4.0 Ghz.

That VCore seems pretty high to me. A stock 8370 (4.0-4.3Ghz) typically runs 1.35-1.4 range.

Regardless, that board is a 4+1 phase, never intended to run an 8core; let alone an 8core that's essentially a pre-overclocked, 125W chip.

Ultimately, I wouldnt invest any money in that platform - so keeping the voltage (relatively) low and dropping the core count if necessary is all you can do.

Also, TEMPS arent't the problem CPU is about 40 under load even at 4.0 Ghz.

FWIW, they almost certainly are. Just the VRM temps, not the CPU temps.

Both revisions of motherboard support the FX-8370.

I don't see any listing for "G.Skill Ripjaws DDR3 1866 4GB". Maybe it's just carelessness. Could it be RipjawsX or Z? Can't really tell what memory you have without a part number or link to it. Also is it possible you bought modules sold as singles and not a 4GB x2 kit?

Depending on what motherboard revision you have, you may need a BIOS update.

Lots of boards "support" the 8370 - lots of boards "support" even the 9590.

But, in practice, that "support" is theoretical more than anything else. Support is there from a socket & BIOS standpoint. The power delivery/VRMs are just not capable of handling the higher core chips.

Yes, I should've specified CPU TEMPS* sorry. I should add that I installed a NF14 PWM blowing on the VRMS.

And my stock vcore is 1.3875*.

I flashed BIOS to latest version, so that's ruled out.
