Hi everyone!

Thanks for your time in reading this thread I could really Use some help with my Phenom 955. It is c-3 stepping.My current set up is

CPU clock is at 3.7ghz with 1.375 Volts
Cpu Northbridge at 2400mhz at 1.200 Volts

That set up is 100% stable. A p95 test for 10 hours proves it for me.

The PROBLEM:
When I overclock the CPU to 3.8 ghz I up the Voltage to 1.400 and I get a BSOD in about 2 minutes of running P95. Therefore I did the logical and upped the Voltage to 1.425 and ran P95. This is Stable (Without Crashing) Yet my Temps are WAY to high about 60-62. I do have a Hyper 212 Evo Air cooler.Should i do water cooling? Is the jump from 3.7-3.8 that big? But I've heard of people bringing this sucker to 4.0ghz with the same Cooler. Somethings i'm doing wrong? I'm a little new to the website so i'll link the photos from Imgur.com

Basic Specs.

Motherboard : GA-770T-USB3
GPU- EVGA geforce 760
CPU- AMD phenom ii x4 955 c3
Memory:8 GB.

Here's a few pics of CPU-Z at 3.7ghz with my mentioned Voltages above.

Thanks in advance!!


Edit: Sorry I didn't realize there was a Overclocking category. Hopefully it's okay if not I can make a new one in that category.

Leave it at 3.7. There is no way any human could tell the difference in the 100 MHz. Not even with a stopwatch. An AIO such as H110 or H100i would be a total waste of money. A real water loop would be at least $400. It may or may not help anyway. Your mosfets and northbridge and socket temps are probably high too. Hopefully you have good airflow in your case. Start saving up for a new system instead of wasting it for a lousy 100 MHz.

Thanks for the hasty reply! Yeah I suppose your correct. Does CPUID HW/Monitor check those temps you mentioned. And I do have GREAT air flow into my case. 2 Front case intake fans with 1 huge intake fan on top of the case. Also fan on the side to Ventilate further. All in a 70-72 degree room.

Kerns, most people like positive pressure to keep dust build up in the case to a minimum. I have two 140mm front intakes, a 140 mm bottom intake and a top 120 mm exhaust and a rear 140 mm exhaust. Side fans just cause turbulence. I would actually eliminate it. You have to think about air FLOW. The top fans are usually configured as exhaust fans. Also if it is really large it actually does not provide any real static pressure. Many people think 200 mm fans are not very useful for that reason.
