Right, attempted to go beyond my normal overclocks today; and received some interesting results.
Theres some problems which need addressing, but the outcome isn't quite what i expected.
My current system spec is listed below (in my sig) and I suspect the biggest problem is going to be the motherboard.

My MSI K9A2 CF Revision 1 is running the old AMD 790X / SB600 chipset. Proven to be a solid combination, but certainly showing its age.
The board is listed as officially supporting 95w CPU's, from before the Phenom range. I have a custom BIOS installed to support my Phenom II X2 555 Black Edition. For over 18 months, its been overclocked to 3.6GHz (18 x 200MHz) with the core voltage left and Northbridge freq set to 'Auto' and has shown no problems at all.

The HD 5770 has been overclocked for a long time to 900MHz and 1250MHz (over the 850/1200 stock speeds) which has also given me no trouble at all. For a low cost, this has been a very usable gaming PC.

Using those speeds, Bad Company 2 seems to shpwing my CPU as a bottleneck. While playing, the CPU load is constantly 99% however the GPU load is mostly at 70% and sometimes jumps to 100% for a few seconds.


Well this evening I pushed them both a little further....

CPU to 4.0GHz (20 x 200MHz) with a core running at 1.454v and the NB at 2.6GHz (13 x 200MHz)
The 5770 is now running at 950MHz / 1350MHz

For about an hour in Windows, this proved to cause no problems. I could browse the web, watch movies, listen to music, validate both overclocks, post up here, and run the Windows Experience Index. The scores have increased slightly.

CPU Calc: 6.7 upto 6.9
Memory: 7.6 (no change)
Graphics: 7.3 upto 7.5
Gaming: 7.3 upto 7.5
Hard Disk: 5.9 (no change)

I loaded up a simple game (World of Tanks) and proceded to play. All was going well for the first few minutes until the whole system crashed and rebooted itself. The POST screen gave me no errors regarding the previous overclock and continued to load Windows 7 as it usually did. I got back into the game and it happened again; so I dropped the CPU clock down to 3.8GHz and the core to 1.41v, which has remained stable even while finishing the battle I had joined.


What would you experienced overclockers suggest? Have i perhaps pushed them both too far to have both overclocked at the same time?
Should I go back to the old 3.6GHz CPU overclock and retain the new GPU clocks? Or return to the previous GPU clocks and attempt for 4.0GHz CPU speed?

Any suggestions are welcome smile.gif
