cpu/mb degradation ?

I have 4 years old rig now with cpu: amd Phenom2 945 c3 cooled with zalman cnps10x performa and mb: gA-770ta-ud3.

cpu default clocks are 3000mhz at 1.3v.

I made 2 stable oc profiles:

1. 3720mhz at 1.425v. Max 48c under load

2. 3450mhz at 1.30v. max 42c under load

Both profiles were tested prime95 24hr and occt 5hr stable. Each year or half i retested both profiles and everything was stable for 3 and half years.

Few months ago i started getting first blue screens. I retested 2 profiles and both of them became unstable. Occt bluescreen in 1 minute, prime95 bluescreen within 10 minutes.

Started playing with clocks, results:

1. 3720 at 1.425 - not stable

3720 at 1.45 - not stable

3700 at 1.45 - not stable

3600 at 1.425 - stable (but not worth it anymore at this voltage

2. 3450 at 1.3v - not stable

3450 at 1.325v - not stable

3450 at 1.35v -  stable (my current clock i use)

 

Anyone have any thoughts how to explain this ?

Stable oc degraded by 0.05volts or 100mhz. I had C&Q enabled, so oc clocks kicked in only while playing games or heavy load. CPU temps not exceeded 50c and oc voltage in profile 1 is considered safe for phenoms.

 

rest rig spec:

2x4gb kingston value

corsair tx650w

MSI 560ti TF2

ssd 128gb crucial m1

hdd 250gb sata

I'd assume you pushed it too far at 1.425 volts and reduced the chips life.

the mobo VRMs are overheating

 

AMD CPUs can tank up to 1.5 volts

 

going over 1.5 is not advised

 

 

suggest get more cooling to your mobo vrms

assuming an abundance of dust hasn't accumulated, vrms shouldn't suddenly begin overheating

There are many problems here. If I'm not mistaken that motherboard has a very thin PCB which is not good for long term overclocks. The material will become brittle and maybe even burnt, check the backside of the motherboard around the CPU socket for burn marks. Furthermore, the pathways within both the CPU and the power delivery are bound to become more resistent at that amount of voltage with time. The motherboard's VRM is also the very lowest end and it's likely a few of the chokes have started failing.

In case the moderators do not ban me as requested, this is a notice that I have left and am not coming back.

Thats not true. PCB is not thin and VRMS are good quality, rated for 140wat cpus. Maybe you are looking at wrong mb.

i have haf 912 case with 200mm pull and 200mm+120mm push vents. But yea mb doesnt have vrm heatsinks, was thinking it could be a problem,.

I think it's an overheating issue.

 

Are there any burn smells from your mobo?

 

I check the scent of air coming from my hardware when I think something's not right :P

For me I start with the "There's no way I'm not gonna spend $1,000 on a system."

Followed by the "Wow I need to buy the OS for a $100!?"

Then "Let's start with the 'best budget GPU' and 'best budget CPU' that actually fits what I think is my budget."

Realizing my budget is a lot less, I work my way to "I think these new games will run on a cheap ass CPU."

Then end with "The new parts launching next year is probably gonna be better and faster for the same price so I'll just buy next year."

I'd suspect VRMs K10 chips can run 1.5v quite happily. They often have stock vcores of 1.45+

there is no burn marks on mobo.

 

Not burn marks, I'm saying turn the computer on, and smell the board while it's running at OC. Play a game and pause it for a bit just to smell out the board.

What are the BSOD codes you're getting? Might not have anything to do at all with hardware, could just be OS becoming corrupted over time. Use Windows Event Viewer to hunt down the BSOD and post the code, or search on google.

Its 100% from unstable oc, not windows. From testing If i up voltage or lower clocks it will be stable, no bsods.

last 2 bsods were 0x00000124 and 0x000000d1

100% is a fairly lofty number for a 4-5yr old OS. Unless you've gotten the minidump and analyzed/had it analyzed by someone over on the sevenforums I wouldn't automatically assume it has nothing to do with OS/drivers/software. If you have, I would run a memtest at a stable OC since it's probably the easiest thing to troubleshoot at this point (aside from sniffing around :lol: ). The only time I've had a CPU/board die on me it was fine one day and refusal to power the next, not sure how common a slow trickling death is coupled with OC BSOD's -I've just never seen it before. :huh:
