Overclock time! 955 c2

post #1 of 13
Thread Starter 
As I just installed my new hyper 212+ could I do anything else?
First attempt I bumped the multi to 19 or so which puts the speed at 3.8Ghz I then bumped the voltage to 1.45V and started prime95. After about 15 mins of no errors I rebooted and went to 4Ghz. The bsod was instantaneous. Not in the least discouraged I kept increasing the multi until I hit 1.55 still no luck prime always meant near instant death.
So I went back to 3.8Ghz with the multi at 1.42 prime is chugging away in the background as I type this no bsod in sight. (temps are 48-49)
I'm pretty happy with 3.8Ghz though I wonder why I can't get it to 4 even at 1.55V I imagine it could be my mobo as the 955 isn't even officially supported.

Edit: Oh did I type c2? It's a c3.
Edit2: At this point I've backed down from seriously overclocking it due to my board's weak VRM's.
At the moment I'm wondering what the max safe range would be. Currently I've confirmed I can keep it stable at 3.8Ghz with the voltage at stock.

Honestly mate? I suggest downclocking even from your current OC due to limitations with the board. The Biostar has a bare 4+1 phase setup, not meant to handle the load of a highly OC'd 125w quad. You risk damaging the VRMs (and thus the board in turn) if the chip is kept under constant stress. This is doubly risky since i assume you have no aftermarket heatsinks installed on the MOSFETs?

I agree. I wouldn't OC on that board. It's too dangerous. IDK why you have such a cheap board. FYI, the most expensive components of your build should be the MOBO and PSU (if you plan to OC).

Ah well thanks for the warning guys I don't feel like frying this board just yet so I've clocked down to 3.4.

Quick question guys, do you think it would be safe to clock it as high as I can as long as I keep it at stock voltage?
I'm asking Because I just clocked it up to 3.8 at 1.35V.

yes..btw..you forgot an "8" on your motherboard in your sig rig.And I wouldn't be pushing it too hard..until you get a better board for OCing.

What is your memory settings at? And have you tried upping the NB or HT speeds?

As previously stated though, that motherboard is going to hold back a good long-term OC.

On another note though, my 955 BE C3 on an Asus M4A89GTD Pro/USB3 couldn't get past 3.8 GHz with a 212+ and I barely got it stable at 3.9 on my Fatal1ty 990 FX with an H100. you might just be near the limit of your ships if it won't stay stable with that much voltage.



If you really want to maintain a high OC on that board though, look in to getting some heat sinks on the CPU power phases though.

1.55v sounds way too high for a hyper212 to me. When I had my hyper in push/pull w/shrouds I ran 4.0ghz at 1.5v, then after upgrading to water I switched to 4.2 @ 1.55v
But every chip is different.

The TA 790GX 128M uses a 3+1 phase setup and yes it IS known to fail when being stressed way past its limit, DESPITE HEATSINK COOLING - there have been one or two recorded failures.  This VRM setup does not have the CAPACITY for an overclocked 125W processor. I do NOT recommend an OC on this board.  Return the CPU speed to stock.  Try undervolting.  And for your own dearest sake, get rid of the Hyper 212+ and put the AMD stock cooler back on there - let the VRMs actually have some AIR

 

Speaking of C2s they actually run cooler despite higher voltages compared to C3 o_O must be die size related.  So as long as you are within the 62C temp limit you are fine.

What are the safe chipset temp ranges? Oh and Is there a tempurature sensor on/near the VRM's?
