Overclocking the 960t with DDR2

post #1 of 30
Thread Starter 
I have have an AMD 960t unlocked to 6 cores and want to overclock.

Current Specs

960t unlocked to 6 cores stock voltages

8gb Patriot DDR2 800

Asrock a770de+ motherboard

Cooler: Stock cooler from AMD 6000+

Graphics: 2x HSI 6850 1gb xfire

1st Question: Will I see overclocking performance gains from switching to ddr3?

2nd Question: The Bigger cooler seems to run hotter idles at 45c load 55-60c did I do something wrong when installing this that would cause these higher temps?

3rd Question: I have a Apevia Xcruiser case with room for a decent size air cooler or something like a Corsair H80, what is suggested for keeping this cpu at the lowest temps for overclocking?

Be careful overclocking on that board with an unlocked X6.

If you install heatsinks on the vrms and ensure you have good airflow..you may be able to oc to 3.5-3.9 depending on how hot the mosfets and chokes are getting under load....as long as your at stock voltages they should not get to hot

I think I'm having trouble finding my board on that list I think its am2 am2+ but also supports am3

I don't belive theres any recorded vrm failures with the 770de. I own the ddr3 version and i've touched the chokes on full load with an x4 960t at 4ghz and they don't seem TOO hot but with an x6 i would think they'd be hot. Try aiming a small fan towards vrms

OP: The 770DE's are great budget boards. Though, unlocking to x6 I have no experience with.
My ddr3 version will take my 955c2 to 4ghz in cold weather on air,but for an x6, I would probably keep under 3.8ghz and only with an after market cooler like you suggested.

What I'm really trying to figure out is if my overlocks are being limited to the memory controller being ddr2 or if I will gain anything by switching to ddr3

not sure which components are the vrm's I would like to put heat sinks on them but not sure if they are the big squares or the little rectangles lol after an hour of Googling still no clue?

VRM's are the little rectangles right next to the large squares.

Low quality side 4+1 phase.  On a 6-core processor, capacity may give you trouble higher on.  I do not recommend passing 1.45V on the CPU voltage.  Of course, cool everything, or you won't be ready for overclocking altogether.

Like XD said, 4+1 phase is not recommended for a 6 core AMD CPU. However, if you can't afford to buy a better mobo, I'd suggest going back down to 4 cores and overclocking then. It puts less stress on your VRMs and could theoretically allow you to overclock higher (less power usage).

The optimal way would be to replace your mobo, and definitely your CPU cooler. Your temps are way too high on load, and should not pass 62C, even 60C is pushing it. And considering you're already at 60C without overclocking, I suggest you immediately purchase a better cooler before you do any overclocking, unless you want to damage your chip.

I'd recommend the H80. It's not the best cooler, but I've always liked the Corsair closed loops. They do exactly what they're intended to do, they're high quality, and you get to say that your PC is watercooled.
