Having trouble overclocking an AMD Phenom II x4 C3 beyond 3.6 Ghz - Page 2

Thanks for the offer, but I run a mATX case for LAN partying.

Honestly, if I could open the door to being able to run dual graphic cards while maintaining the ability to keep my mATX form factor and support all the existing hardware I run, I think I would be comfortable in the lower $100 range. No more than $120 perhaps, unless of course a small jump was going to pay huge dividends.

Basically I want the most board for the money while staying closer to the lower $100s.

mATX is tough in that there are fewer quality AM3 boards with a decent VRM design suited for 965 overclocking.  Pretty much all of them have 4+1 phase design and a majority of them don't have cooling - as a minimum, if you are going to be overclocking a 125W TDP processor, you should be looking for a quality transistor-based 4+1 phase VRM design - and you should be ensuring that VRM cooling is maintained as well.  Some 4+1 phase setup with lower quality transistors have been known to fail or have problems.

 

Dual card on mATX is not too ideal because of a potential lack of space so that the paired cards can actually get airflow.  Also, so far the only mATX AM3 board enabled for CrossfireX with 2x PCI-E x8/x16 slots is the MSI 890GXM-G65 and I do not recommend it at all because it has a badly designed VRM setup that actually has a very high failure rate with 125W TDP processors.  There must be lack of interest because I haven't seen antoher board so far that can do it; I had heard that there were going to be 900 series boards on mATX but looks like we may have to wait for 1000 series chipsets.

The TA890GXE would suit you fine.

The TA890GXE is the only mATX AM3 board that already includes a decent VRM setup with cooling.  However, it is hard to find nowadays.... :( also, only one PCI-E x16 slot

I could live with one PCIx slot. Generally, 1 of the leading graphics cards benchmarks higher than 2 of the runner-ups from what I've seen. I will see about finding that board.

Best high quality mATX AM3 choice for price with a moderate-high capacity 4+1 phase VRM system that should have no problems handling the 965 overclocked's TDP requirements (provided you ensure the VRMs are well cooled through the addition of VRM cooling such as heatsinks or a fan such as the Antec Spot Cool) - ASUS M4A88T-M for $80 shipped; heatsinks can be had for $5-10 shipped (i.e. Enzotech MOS-C1 but some other stores have non-branded ones for cheap, or if you have small heatsinks you can reuse, perhaps even cut up, they will work) or Antec Spot cool is $13 shipped and has nice flexible mounting)

 

The GA-78LMT-S2P also has a decent 4+1 phase VRM setup (that uses a 3-transistor design but has high quality transistors, thus the third transistor which acts as a driver does not hold back the setup as much) and so long as you ensure proper VRM cooling on it (again, heatsinks?) it has the potential to push a 965 without being unsafe.  However, it is again a lower capacity VRM setup; you may be seeing protective shutdowns (that prevent VRM overheat/overload that can lead to failure) in the late 1.4V-early 1.5Vs.

 

As for chipset you pretty much have no choice but to get a chipset with IGP since that's what all the mATX AM3 boards have.  I've seen 785Gs and 880Gs push to 4Ghz with the black edition chips a couple of times, ref clock is really not as flexible however.
