How high can I go on this board?

post #1 of 9
Thread Starter 
Specs in sig but my board is now a Gigabyte GA-MA78LMT-US2H. How high can I OC it to? Would 3.3GHz @ 1.425v be okay?

Does anyone actually know the Athlon 630 stock voltage? AMD site lists 0.95v-1.425v, but each board I've had this chip in puts it at either 1.325v, 1.375v, or 1.4v. CPU OC calculator @ outervision lists 1.3v, but I can't work out the wattage of this thing without knowing stock.

.
GA-MA78LMT-US2H4+1No125W (no x6, no 3.5Ghz+ x4)125W max, no OCNo3 transistors8-pin

That alright then? Really don't wanna risk frying this board at all.

On a side note, got rid of the M4A79XTD-EVO pile of junk since it kept crashing randomly, eventually it started turning off and rebooting telling me that "**ALL 4 CORES HAVE BEEN UNLEASHED!**", which shouldn't have been too hard since it's... well... an Athlon II X4, but it still managed to do a really ****e job of it by not being able to boot into windows.

Turn off ACC on the M4A79XTD EVO?
It's a 95W processor and that is a good method of safety but it is a VRM design from 2007-2008 that has known problems. I say an OC would be fine but limit yourself i.e. never pass 1.5V, and try and get some cooling on there.

That's the thing, it'd turn itself off and enable ACC whenever it damn well felt like it

Think I'll try and get a decent stock voltage OC, the chip is stable @ 1.2v 2800MHz, so I can work from there.

I see, perhaps you should try RMA if you are within warranty.

Have done, but can't afford to be without a comp for 31 days, so I've bought a new board and will return the old one for a refund with the retailer. Similar to how the Sandybridge replacements were done.

Also, I've set it to 1.345v/3.12GHz, which could either be 95W or 115W depending on what the stock voltage is have contacted AMD to see if they'll give an actual answer outside of 0.95v~1.425v.

GA-MA78LMT-US2H can handle a 125w or 6core cpus at stock speeds. I have a Biostar A780L3G 4 phase power and it can running a 1090T x6 and a 970 x4 cpu at stock speed.

Just wanna be careful about it really, the last boards I've had are:

MSI GF615M-P33 - needed a BIOS flash, which didn't work
Second MSI GF615M-P33 - 3 phase VRMs popped
M4A79XTD-EVO - Random crashing (got educated about phases, hence buying an 8+2 board)

All in the space of a few months. That's why I'm being so overprotective about it This board's running without a hitch luckily, the others were all funny from the start with POST problems

Are there any risks in running 50 IBT passes on high after the 4 hours I've just done? The CPU is 88W from undervolting, 3.12GHz/1.25v. Should I let it cool off a bit?

I know it's a stupid question again but I really don't want to risk losing this board, I can't afford it one bit. Dreading that moment where it shuts off without warning never to boot again... again

Cheers

IBT is usually more CPU/temp/TDP heavy than Prime95
Since you are below 95W TDP and this is a 4+1 not 3+1 on this design, I say it's okay

Processors usually cool immediately after stability tests anyway (if the mounting was good. I know someone else with a D14 on a 4Ghz x6 which runs hotter than mine and takes longer to cool down... the TIM and mounting must've been worse
