Buy or No Buy? ASUS M4A87T AM3 870 ATX

post #1 of 11
Thread Starter 
So, newegg has the ASUS M4A87T AM3 870 ATX for $50 after rebate & coupon code. On the AMD Motherboard VRM information list it lists it as having 4+1 phasing. now i know MOSFETs can range widely in quality so 4+1 could be absolutely terrible or just acceptable.

[ame="http://spreadsheets.google.com/pub?key=0AgN1D79Joo7tdHhjbllGOHczUU5fM0VxUHVXXzlLM1E&w=120&h=550"]In the AM3 phasing list it's listed as[/ame]

M4A87T(D)(/USB3)

Phase count (VRMs)
4+1

Heatsinked?
No

CPU TDP support
140W

VRM protection?
Yes - throttling

Transistor info per phase
2 transistors, 2 drivers

CPU power plug
4-pin


Will this be dangerous to attempt to unlock a Phenom II X2 560 to quad & OC?
Will this be dangerous to attempt to unlock a Phenom II X2 560 to quad but not OC?

Will this be dangerous to attempt to just OC a Phenom II X4 955?

I'm looking for a cheap backup build that i can re-gift as a HTPC for xmas. It will use a 9800GTX+ (low power GTS 250 revision) that i have lying around.

With the coupon the PII x4 955 is only 15 bucks more than the x2 560 so I'm debating whether trying to unlock is even worth it when i can be guaranteed 4 working cores for so little more.

However, I would like to do at least a little OCing.

Thoughts?

Not an owner of this board.
An 870 motherboard with an 850 southbridge is usually a decent board. I'm not familar with this particular one.
As appears normal on cost cutting there are no heat sinks for the VRMs.
Part of the no onboard video, I suspect.
The only obviously discouraging feature is single 4 pin socket instead of 8 pin.
It is a lower end version that should work very well.

Heck ya man! Snatch the board up!

I have an older board than that and it's fine for me. No issues so far.

soooo.....

I'm not risking disaster if i get this and push for a decent OC?

What would be a safe OC on a 4+1 phase like this for a 955?

Not dangerous, definitely ensure VRM cooling for proper operation. I'm sure that due to the low motherboard cost, this wouldn't be an issue.

Worst case scenario, hot/overloaded VRMs will cause protective throttling to activate. However, this may cause loss of performance, if the VRMs aren't properly cooled.

What would you recommend to cool them? Those Enzotech MOS-C1 C1100 Forged Copper Heatsinks in the VRM sticky are OOS on newegg.

I'm guessing I have to get a TIM that's also an adhesive right?

I used MOS-C1 on about 4 builds now and they work great.

The ones they come with. Sticky pads they harden up when warm up.
