Don't use M-Flash. Both Riskitall84 and myself had it screw up our boards. Use a DOS boot drive.

2133 mhz gskills work in that board

Supposedly they will work in the board but they will not work with current AM3 chips that high. 1800Mhz seems to be the highest that the AM3 cpu's can run.

Is the RAID chip on the board any good? Did not see much discussion in the thread about RAID other than to use the 6 black ports. I assume it will still put a load on the CPU? Going to set up my new build with a RAID 0. Debating on using the MB or getting a controller card...

Ryushin

99% of all the on board RAID controllers are actually software RAID with drivers written to make them look like a hardware RAID to the OS. Though I think the JMicron controller on this board with the two ports is a true hardware RAID chip. They should have done it the other way around. Make the 6 ports be a hardware raid and the other two ports just act as SATA ports. But that would have have at least doubled the cost of the board if not triple if they had done that.

All software RAID controllers, such as the six SATA ports on board will use the CPU. As long as you aren't doing RAID that needs to calculate X/OR parity (4, 5, 6, 50, 51) then the cpu hit will be negligible if anything.

So your answer is that for RAID 0 you won't need to buy a board. I'm running RAID 10 with four 750 GB drives and it's very nice.

I am planning on RAID 0 with 2 300gb VelicoRaptors. Looking at a Deskstar 7K1000 for a back up. RAID 10 was not even on my radar.

So you are doing your RAID 10 from the 6 ports on the MB then? I only have experience with RAID 0 (run one for the since 98), Any thought on how is the performance of the RAID 10 vs RAID 0?

Ryushin

If you are just going to be using two drives, you might as well just the J-Micron ports (ports 7 and 8). That's supposed to be true hardware raid.

If you are going to run more than 2 drives, then the AMD software RAID is your only choice.

A basic RAID 10 vs. RAID 0 would be thus:

Pros:
RAID 10: Fault Tolerant, Good Speed (If the driver is written properly, Reads will be just as fast as RAID 0, Writes will be half the speed)
RAID 0: Nothing is faster. Period! All the disk space is available.

Cons:
RAID 10: You loose half of your disk space. If you have four 300GB drives, you'll only have 600GB instead of 1200GB with RAID0, slower on writes then RAID 0.
RAID 0: Not fault tolerant in any way. If you loose one drive, you loose everything.

I thought I read in this thread that the 2 J-Micron ports are not as fast as the 6 ports? Post #437

Correct

Guys! Look who's back!!!!

At last my GD70 is back from RMA! Got me a new CPU cooler too so will get it built and get back in the game!
