Hey all,

I am trying to put together a new system and was wondering if I should buy a 1.6a and overclock it or just buy a 2.0 chip?

Also, is that MSI board a good choice or should I consider something else?

Thanks for the info.

I have this board with a 1.6a and am very happy. It will get poopooed here because of a couple things. If you are looking to get the maximum crazy overclock then you don't want this board. If you want a full featured board that has shown itself to be rock solid to me this is a good choice. Been running at 140fsb for 2 months now with nary a hiccup.

Good Luck

I have a MSI 845 Ultra aru. Its an excellent board. Very overclockable!
A couple things I do not like about the board.
1. memory timings are set to 2.5-3-3-7 when you push the board past 140fsb.
2. Temp reading are flaky. Shows my MB temp at 46c and cpu at 60c full load, but it should be in the high 40's tops!
3. No agp/pci locking feature. This allows the agp and pci to stay at default speed when overlocking the cpu/memory. Alot of the performance MBs have this, but MSI left it out!

Other than that its a real performer! Im running at 160fsb stable as anything ive ever ran!

Awright.. am I the only schmuck that can't get my MSI / 1.6A to overclock? :)

I have the board, a boxed retail 1.6A, a thermaltake mondo cooler and a stick of 512k PC2700 Mushkin memory... throw in a GF-440mx and a 3Com LAN card and I can NOT get this thing to boot with a FSB higher than 106. I am using onboard sound (yeah, I know...) but I have turned off the RAID controller.

No kidding... nothing higher than 106.

I've been dooin this stuff since the 300a's... I've set the V up to 1.65, I've neutered the memory (200 instead of 266), I've messed with all the BIOS options I can but it won't POST past 106.

Help? I feel left out!

Well, the only thing I can suggest doing is the usual, pull all but your video, ram, cpu and see if if boots. I have the onboard sound enabled. I'm able to boot and run stable up to a 145mhz bus, anything over that, and the cpu will not post, I have tried with the voltage cranked to max in the bios, but havent tried the voltage mod on the processor, so that may or may not help. Other than that, I would guess you may be one of the unlucky few who just received a not so overclockable cpu.
