1st time OC - not sure how to proceed

post #1 of 17
Thread Starter 
I read logan's guide here, and slappa's, and some other ones i managed to find on-line.
I am still unsure what is the correct order of doing things.

I already changed the multiplier to x18 in BIOS, just to see if I can get away with changing just that, and it's stable @ 3600mhz, with only 1c higher (38 load) (didn't touch the voltage, it's 1.275v at the BIOS, tho on CPU Z i see it go as high as 1.376v during stress testing)

From here however, i don't know what i should be doing next.

should i tackle the RAM? it's running at 670mhz according to CPU Z.

should i continue tweaking the CPU? and if so, what next? just increase the multiplier until it fails, and then increase voltage one notch at a time until it's stable? i find that hard to believe, feels.. too easy

what about bus speed, or northbridge settings? should i even be touching those?

hope i'm not rehashing too much.. thx guys rolleyes.gif

1. RAM is totally upto you however know this, for some people, they can only overclock 1 or the other so you may not be able to OC your RAM
2. That is the goal of overclocking smile.gif like before its upto you, just make sure you dont melt your CPU in the process wink.gif
3. i dont know that much about bus speed but for northbridge i OC'ed mine from 2.1 to 2.2 and according to cinebench i got a slight improvement (3.55 points to 3.60)

Thx, but it doesnt really help me, I know it's up to me, that's why Im asking how to go through with this smile.gif.
I want to ay least get my ram to rated, and get the CPU up to 4ghz.
How should I proceed? Ram first? If so then how. CPU first? If so, then should I just play with the multiplier, or should I up the voltage in advance?

This should help you a little, try to read through it all, but you can skip to nb section and if you want ram.

I think one of the main goals is to get your ram at a 1:1 ratio, so sometimes people have to actually underclock their memory to achieve this. I would leave memory an vcore on auto for now until you get the hang of things and just up the multiplier until it is unstable and then try to up your vcore just a little until it is stable.

On the memory, you could also set it manually to the factory settings if you want just so you know it is running at the rated speed.

It looks like you are using the same ram I am (gkill 2x2gb 1600 @ 9-9-9-24?). If you give my post a quick look.. here, you can see how I found the ideal memory settings. I got better performance by dropping the ram multiplier to 6.66 (registered the ram as 1333 instead of 1600), and pushed tighter timings. You should be able to find your JEDEC settings in CPU-z for a starting place.

As far as the CPU, I know a lot of people have the 1090T on here, they will be better able to help you than I.

I would suggest turning your RAM and CPU multiplier down by 1x and pushing the Clock Speed as high as your comfortable with before starting on the CPU.

You can go about it a few different ways, as other pointed out.

You can OC just your CPU, by fiddling with the multiplier.
You can OC both by fiddling with the core and multi. Just watch how it affects your RAM. When I do it, I like to manually set the RAM voltage, and timings, and then set the speed to auto, so your core x HT will adjust the RAM along with the CPU (core x CPU multi).

But basically, yes. Just up it slowly and stress test it each time until it blue screens, and either back it off, or up the vcore until it's stable. Adjusting other voltages might be required to get it higher, especially the NB to keep your RAM stable, but only if you're aiming for ~4.0GHz.

There needs to be a thread like the Phenom II x3/x4 for known settings of stable OCs. I can't see any for the x6 ones.

thx everyone, good info. the article was a great read too, weird i didn't find it in my googling.. biggrin.gif

2 things before i get started-

1. according to CPU Z and tusk's post, my RAM is already running at stock speeds (9-9-9-24-33-2T @ 669.5mhz), but the FSB is 3:10, which isn't the same as dolk's article's 3:8 for this DRAM. should i change it? should i start OCing the RAM if it's already at stock?

2. the only thing i've done so far is increase the multiplier in the BIOS to x18 (3600mhz). on idle, the system is running at x4 (800mhz), and i'm seeing a voltage range of between 1.336v (idle) and 1.368v (load). temps are fine (27-37). is this voltage range normal? does this mean that the mobo is auto-setting the voltage according to the CPU's power consumption? from what i read, voltage should be my first wall, and i've gotten 400mhz OC without even touching it. is that normal?

Turn off turbo in bios when overclocking. I would set the vcore manually to stock volts when beginning to overclock auto will raise vcore as you overclock,and not always to the optimal setting. Gradually raise the multi until it becomes unstable, then raise the vcore slightly until youre stable again. When you reach a point where increasing voltage no longer brings stability your last stable setting is your max multi setting. set the multi and vcore to stock and do the same with the fsb. I'ts more involved than that, there is a great guide somewhere in this section do a search it was a great help to me.

Crank her up. Max voltage is 1.55V so keep it under that, try to get 4.0GHz at 1.5 or 1.52V but watch your tempature's, keep your CPU tempature below 62C - ignore the Core temps.

Get northbridge up between 2.7-3.0GHz
HT around 2000MHz

RAM, You would have to twink yourself as all RAM is different to overclocking

Get CPU-NB upto 1.35 and keep it under 1.45V

RAM upto 1.6 or 1.65V which depnds on your timings or speed you have set it.

NB upto 1.28 or 1.3V

CPU/PLL - ignore
