maxokeeffe

hi there

need some help overclocking my 990x, im currently using the corsair hydro h50 cooling unit,

currently i have disabled the turbo mode, and i am set to bus speed 133, multi, 27. volt, 1.232 .

i want to run it around 4.2 4.4 ghz,. iv been trying uping the multi etc, but it just crashes, iv also up the voltage but it runs v v hot,

any idieas

If I rememeber right, you said you were running your 990X at 4.2 with a max temperature of 66°C on the stock cooler. So I was right - bull.

Have you overclocked before?

For me to be of any help, I need to know your stock settings, to see what you've changed, and how much, etc.

hi mate

currently this is what its set at , bus , 133mhz, x 72 multi, core voltage 1.232 volts. , speed 3597.8 mhz,

can u help me to get it running at 4.2. or 4.4 mhz, i im finding it hard to stabilize it ,

You didn't answer what I asked. Luckily Intel gives you most of the stock settings online.

So you've bumped the multiplier up one. What's the stock voltage?

Edit: Why do you even want to overclock this chip? What's so stressful that you need more power than what the 990X gives you by default?

Everything on the above message is stock. That's what the defaults are. Why does anyone ever wanna over clock. See what it's capable of doing. Plus I use alot of CPU power doing what I do

Multi of 27 isn't stock. 133x27=3600. Stock 990X speed is 3460.

What do you do exactly?

Bump the multiplier up one, run Prime95 for an hour. If it's stable, and within your temperature limits, bump the multi up again.
If it's not stable, but within your temperature limits, increase the vcore one.
If it's stable, but not within your temperatures limits, drop the multiplier back one.

When you've found where you think you're going to stay, run Prime95 for twenty-four hours. Follow above rules.
Rinse and repeat.

Hi there

Thanks for all your info. Just 1 more question. What core temps do you think is max for an 990x. So I know what I should stay within. Also. Im a 3d rendering specialist.

Thanks.

Serephucus

70°C with your hottest core, under P95.

I'd like to see some of your work...

I can show you some of my work if you'd like. also I stock bus speed I found on the chip was 143 MHz. but I was told to leave it at 133 for Overclocking. Shud I leave it at 133. And just do what u said. With your rinse n repeat method. I have the corsair h50 unit. I found a high rpm fan. Of I changed fan on the rad of the unit with the high rpm. Would that make it cooler. Sorry for all the question s. But this isn't my area. Ha

Thanks

Serephucus

Stock speed is 133. Whoever told you otherwise is an idiot. Yes you should leave it. H50 will be fine. High RPM fan is good.

If you break it, I'm not responsible. Just getting that out of the way now.

If I break what. ?? Would changing fan to the Hugh rpm. Cool the pc more.

Serephucus

The processor. Yes.

Hahaha. And how would it break.

You screwing something up.

If you follow what I laid out, you'll be fine, but that doesn't mean people haven't found ways to break virtually unbreakable things before.

I'll follow those steps lad. And when its running to hot I'll just lower multiple. Etc.

Do you think that High rpm fan would lower temps alot.

Thanks.

What makes you think I have the slightest idea? I've never used a 990X, and I've no idea what the two fans are!

Give me the specs of both fans, then I can give you a rough idea.

You should haveore confidence my friend. Spec are. Coolmaster 120mm 1600rpm. High rpm is also coolmaster but 4500rpm

Serephucus

High RPM fan will be better, but probably not by a whole lot.

THATS MY SPEC AND TEMPS SO FAR , RPIME RUNNING 40MINS

Serephucus

Fail fail and more fail. No-one can read that.

It's 135 x 31. Volts 1.29 Volts. Mac core temp after several tests 58c. So I'm v happy.

Serephucus

What were you testing with, and for how long?

Tested it with intel Burn test. Prime95 for 1 hour. So the max core temp I got was 58c. So I think thats gd going.
