Hi Guys , First post in the forums so ill make it a good one Im trying to overclock my AMD 720 x3 , Specs of my system are as follows. Msi 770-c45 , V1.3b2 bios 720 X3 (Wont Unlock ) 4gb Ocz Platinum 1600mhz @ 1.8v Ati Radeon 4850 512mb @ Stock (For Now) 550W enermax , 36 amp rails. Spire Thermax II Cpu cooler. Ok so the story so far is that I can get the chip to 3.2ghz absolutely stable with prime . Settings are 200 x 16 , 1.3375v @ 29°C under load. Once I knew that was stable I tried for 3.4ghz , 200x17 1.4V 32°C under load Ive tried setting the HT link to 1800mhz and NB to 2000mhz but it still wont improve stability for any longer than 20 mins on prime. Ive tried lower and higher voltages on the cpu but still cant get it stable for more than 20 mins on prime. Worst was 3400mhz 200X17 1.385v , lasted 2 mins in prime I have CnQ turned off , C1E is disabled , ram is running unganged and only at 1066mhz @ 1.76v while OCing. Any help would be greatly appreciated. Thanks guys.
Not really the answer you need but for gaming why did you get a Phenom X3? They are kinda pointless, lower clock speeds than Phenom X2 and less cores than Phenom X4... they are kinda pointless Try raising the voltage on your northbridge, it may or may not help but worht a try
No your first post wasnt too helpful at all. The 550 X2 wasnt available at the time , the 955 was 100 euro more expensive. And the rest of the x4 phenom 2's all have locked multipliers.I hope this answers your question for you. Ive upped the NB voltage a bit but doesnt seem to help ...
That's completely BS, why must everything be in even numbers?? The X3 is not that much more expensive than the X2, but it's waaaay cheaper than the X4. It's also unlocked and overclocks just as much giving an extra cores worth of overhead to play into. The overclocking potential of the 550 and 720 are about the same because, they are effectively the same Agena core underneath. It's a shame your X3 won't unlock, but are you sure that's the latest BIOS available? The limitation of Phenom IIs is voltage and temperature - keep it cool and crank the voltage and it will keep going. I've not yet played with the C45, but will soon, but crank the VDDC with CPU core as well - bearing in mind some heatsinks on the MOSFETs should help there.
Hey bindi, when did you get the hammer on your Avatar? Oh and back to the topic, what's your FSB compared to your HT and multiplier? Because the easiest way to increase clocks is to lower the FSB and shove up the multiplier in these chips. Although Bindi has a good point, the thermal output is still the main concern.
Getting the exact same combination CPU/mobo arriving on Tuesday so I'll give it a go and report back end of next week or early week after In the meantime, what are MOSFETS and how does one cool them? I remember hearing vaguely that this mobo has some heat problems somewhere but I didn't quite understand...
