ASUS M3A78-T vs. ASUS M3A79-T

post #1 of 10
Thread Starter 
Besides having more pcie slots and the abilitly to run 16x 16x cf is there a reason to buy the M3A79-T. I am leaning towards the ASUS M3A78-T. As I dont need all those pcie slots. I can live with 8x 8x cf when I get another 4850. This will used with a Phenom 2 940 when released.

Im looking at open boxes at the egg.

ASUS M3A78-T- $91.53
ASUS M3A79-T- $132.75

Is the $40 going to yield better OCs?

the 79-T is the FX model. it's the top of the line amd chipset.

the 78-T is the GX model. it's basically an FX with integrated graphics. and i believe it's on a smaller fab process, as well. some people believe it yields better OC's than the FX model.

both are great and you can't go wrong.

I have the M3A78-T. I bought it for the versatility of using it as a HTPC I do plan on getting the 9-T Deluxe as my true gaming rig. Like the previous post you can't go wrong either way but if it's price then go with 8-T.

i got the 78-T and its glorious, not super super high end, but more than what most would need for decent overclocks. Good thing about it though, if you wanted to watercool your NB, then the lack of Heat Pipes will make your life easier.

I bought the 78-t because i heard it was "easy" for overclocking. This was my first build, but i cannot get the OC'ing to work for the life of me. Don't mean to hijack a thread, but can anyone give me any assistance?

CPU: AMD Phenom 9850 Black edition quadcore 2.5 ghz.

I hear this cpu is easily OC'd to 2.8 or 2.9...can anyone help a newb out?

basically, just go to the "jumper free configuration" tab, or "AI Tweaker" tab (just press the right arrow key once and you should be in the correct tab). the top most setting is usually the "general overclocking" setting in which you can select "auto", "manual" and possibly a few other things. set it to manual and a few other options should appear. go down to the CPU Multiplier and select 14x to get you 2.8GHz (200MHz reference clock and 14x multiplier), 14.5x to get you 2.9GHz or 15x to get you 3.0GHz.

2.8GHz should be fairly easy. getting more may require you to bump up the CPU voltage.

Thank you pixie, worked like a charm! I set it to 2.9 without any change in voltage. Now to work on getting this board to recognize my "CORSAIR XMS2 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)" as 1066 mhz instead of 400 mhz. Any guidance would be appreciated.

nice job on the OC.

lol yeah, i'm running the OCZ DDR2-1150MHz ram and i don't really remember if it ever defaulted to 1066MHz or not. i've always been setting it manually. anyways, under that same settings tab, scroll all the way down and there should be something that's says "DRAM timing configuration" or similar. go into that sub-menu and the first option should be have 3 different settings - "Auto", "Limit", "Manual". set it to "manual" and a few more options should pop up. click on the frequency selection (it'll probably be default at 400MHz) and select 1066MHz.

note that these new BIOSes are somewhat intelligent in that if you were to up the Reference clock, say from the default of 200MHz to 250MHz, what would appear in the memory section for the different speeds would be 500 (for 400MHz), 667 (for 533MHz), 833 (for 667MHz), 1000 (for 800MHz), and 1333 (for 1066MHz). which is nice because you don't need a calculator to figure out what your ram speed will be if you adjust the reference clock, you can just plug in a number and go see.

Well i found the menus you are referring to, but if i select 1227 mhz (which i'm assuming is 1066) my os doesn't load. Is there something else i'm supposed to be changing to alter the voltage or timing?
post #10 of 10
well that's just it, when you are selecting 1227MHz... that's what your ram is running at. so if your ram isn't capable of running at those speeds, you need to either select the multiplier that is one lower (940MHz assuming you still have the ref. clock the same at 230MHz) or lower your ref. clock and use a higher cpu multiplier to achieve the same cpu clock speed.

i would just select the ram multiplier that shows a lower number than what your ram's rated speed is. that way you'll know that the ram isn't a limiting factor in the CPU overclock. get it?
