MSI 870-g45 HT question

post #1 of 3
Thread Starter 
Ok, I've been a bit confused as to what some of the settings should be in the BIOS of this board.

However I'll give a rundown of what I am powering this thing with and what all so no one should have to ask further in the thread.

Antec 900 gaming case, all extra fans installed... so cooling and airflow is good.

CPU AMD Phenom II 555 BE unlocked to 4core @ 3.2ghz no oc
still using stock cooling unit on this but only hit max temp of 59c @ 100% usage. Not bad for the little piece of junk when it was designed to cool 2 cores not all 4. idles around 38 to 40 depending on ambient room temp. Also since it's unlocked I can't tell individual core temps but I've been running this CPU for months stable as can be. And I do a lot of 3D rendering using all cores.

4GB of crucial ballistix 1600 DDR3 RAM 8-8-8-24 CR2 timings no oc

OCZ Mod-x-treme 700w PSU

Asus HD 4870 gfx 1gb no oc

WD 750GB Black Sata II HDD main drive

Maxtor 80GB ATA 133 left over from old system. Used to store some files. Has over 35,000+ hours of spin time. Waiting to see how long it goes before it dies.

1 DVD burner

Running Win7 64 ultimate edition

Think that about sums up the parts that are pertinant. I do not have a bunch of external junk connected either.

So, my question is this thing says it's Hyper Transport 3.0 which can go up to 2.6 ghz if I understand correctly. By default when left on 'auto' it sets it to 2000 mhz for both.

I've read a few things that this board shouldn't be pushed on overclocking because the MOSFETs will just end up blowing up on you even though they state it can do all sorts OC functions with OCgenie and the OC switches on the board.

But I've left all that crap alone. The system is fast, but I'd like to at least make sure it's optimized with all the settings I can and I'm not sure if the HT and NB are set right by default. I'm hesitant to change these because of things I read and not sure if the values are correct and that I should just leave well enough alone.

Currently I have them both set to x11 with the FSB at it's stock 200 with the cpu multiplier at 16 for the 3.2ghz on clock and 2,200 on HT and NB. the CPU is running on 1.4 volts and the RAM is 1.67 volts... suppose to be 1.65 for the RAM I have but the BIOS goes up in weird incriments. Voltage for everything else has been left on 'auto'.

I'm seeing some people run less than 1.4 volts on the CPU but from what I read this CPU should run at 1.4 (full load) so that's what I set it at. But if I'm wrong on that please correct me.

Any help would be appreciated. Had a small budget when I built this so I knew overclocking would not probably be an option for a board this cheap. So, I really never tried. And with my confusion on some of the settings in the BIOS usually not a good thing to do when you don't fully understand.

2 things here.
1) HT need to be at 2000.
2) Most Phenom II x4 needs about 1.35v to be stable, but 1.4v will not hurt the cpu.

Ok gotcha. If I am not overclocking the CPU then I don't need to be running 1.4 volts? At that point I'm probably just generating more heat for no reason, so I'll drop it to 1.35 and see how it runs.

Also, what about NB frequency? I can bump the HT backdown to 2000.

Thanks for taking the time to answer.
