Motherboard FSB related question

post #1 of 5
Thread Starter 
Hi guys.

I've been looking into doing some upgrades on my rig, but i've stumbled over a small hurdle it seems And i don't know how big it actually is.

As you can see i have the GA-M57SLI-S4 rev 2. It can support AM2, AM2+ and AM3 CPU's according to it's info page. Okay, everything nice and smooth up to here, BUT... the info page has a really annoying message regarding the system bus speed of CPU's and it goes a little bit like this:

Note: If you install AMD AM3/AM2+ CPU on AM2 motherbord, the system bus speed will downgrade from HT3.0(5200MHz) to HT1.0(2000 MT/s) spec; however, the frequency of AM3/AM2+ CPU will not be impacted. Please refer "CPU Support List" for more information.

After looking over a couple of other products i've found an AM3 only motherboard (the GA-M52LT-D3 rev 2.3) that also displays a similar message:

If you install AMD AM3 on this motherboard, the system bus speed will downgrade from HT3.0 (5200MT/s) to HT1.0 (2000 MT/s) spec; however, the frequency of AM3 CPU will not be impacted. Please refer "CPU Support List" for more information.

So how important is the system bus speed actually and how exactly would it affect a CPU if it doesn't affect it's frequency? Oh... and why would an AM3 only mobo have something like HT1.0 and not HT3.0 directly?

Off-topic: The latest BIOS for my current mobo (FHL) is still a BETA, and if i want to upgrade my rig with any AM3 CPU i'll have to update the BIOS to the latest version. Then again.. i've heard i should keep away from BETA BIOS versions. Anybody else have the same mobo running the latest BIOS? Any advice at all?

Really? Nobody? Not even a single person?

I know my hardware is outdated and all but i had expected at least a reply or two to help clear this dilemma about the system bus speed and how an AM3 CPU would perform.

frist off that is an am2 mobo you have selected with am2+ and am3 support. it is not a native Am3 motherboard.
your bus is like a road. some are 4 lanes some are 1. the mobo you have has well will say 2 lanes. fast car can ride on them (cpu) but some one is limiting how many vheicals are alowed on

thx for the answer noobdown.

now all i have to do is to decide if i'm willing to try out the BETA version of my mobo's BIOS -.- why the heck hasn't GIGABYTE posted a non-BETA until now? it's been like a year already.

HT speed will have little to no effect on over all system performance.
