AMD Athlon II x2 245 (2.9Ghz) Overclocked system optimization

post #1 of 4
Thread Starter 
Hello all,

I thought I'd make my second post, and I'll do my best to ensure some quality.

Long story short, I had a massive PSU failier 10 months ago, and with little budget, I built a new system, and since, I've been making some upgrades over time.

My system currently is as follows:
AMD Athlon II 245 regor 45nm (oem clock 2.9Ghz) - currently @ 3.625 Ghz
Asus Mobo M4A785-M
Kingston HyperX DDR2-1066 4GB (2x2GB)
EVGA GTX 500ti Superclocked (factory set at 981 Mhz)
Corsair CX430 Builder Series
Thermaltake V4 Black Case w/ 3x 120mm intake fans, 2x exhaust fans
Scythe Rasetsu CPU Cooler

My current overclock is @ 3.625 Ghz, with a 250Mhz Bus and a 14.5 Multiplier. The multiplier option in the Bios is now maxed. Bios Version is 1006.

I was running (earlier today) @ 3.6975Ghz with a 255Mhz Buss and the 14.5 Multiplier, but this was *just* below my stability limit, and so I downclocked to current 3.625 for margin of safety.

I'm returning the overclock back down to the 3.43Ghz as noted below, as I am noting some small glitches etc swapping between tasks which normally do not exist.

Thats the meat and potatoes.
System was overclocked by me, to max out the memory at 980Mhz - was not wholey stable any higher. CPU was somewhat stable to 3.7 Ghz, lowered the overclock for longer lifespan and durability to 3.43. Only frequencies and multipliers played with - voltages were not touched (unless automatically done by the bios) nor purposefully increased.

I've attached the individual related screens from Speccy for review.

Again, if I've made any glaring issues or errors where I could get more efficiency, I'd love the input.

I have not adjusted or increased the voltages. For me, thats getting into the danger zone, and I'd rather not blow stuff up, without some expert advise!

Try reducing your RAM down to it's default speed instead of trying to OC the RAM and the CPU at the same time, since it's much more difficult to identify the source of the instability. Always work on one at a time.

I agree, don't try and overclock both at the same time. Keep your RAM within its rated speed, and only overclock the CPU. Also I wouldn't leave the voltages on Auto. I did this at first too, but the recommended way is to set it manually in the BIOS. I would find out the stock voltages for the CPU, CPUNB and initially set them to stock voltage. Same with your RAM. Then gradually overclock till it starts to get unstable, then nudge the CPU voltage till it stabilizes. Make sure you know the recommended safe voltages for your chip. your Vcore should be good up to 1.5V - and you may be able to go a little above this. The CPUNB should be ok up to 1.4V.

Hope this helps :-)

Thanks for the suggestions! Time to grab the ol' manual and read up on the bios settings...
