I recently built a new rig for use with flight simulator (FSX) and I would like to overclock it.

My new system is composed of:
PROC: AMD Phenom II X6 1100T Black Edition Thuban 3.3GHz, 3.7GHz Turbo - http://www.newegg.com/Product/Product.aspx?Item=N82E16819103913

MOBO: ASUS Sabertooth 990FX - http://www.newegg.com/Product/Product.aspx?Item=N82E16813131736

From what I understand about FSX the processor speed is key... I downloaded AMD Overdrive... but I am a bit intimidated by it. I can't get the 3.7GHz that it is supposed to do in Turbo mode.
 
what cooler do you have?

what is your goal speed?

Do you have any experience overclocking before? IF not the best place to start is: Here , even though it is for the original Phenom, the methods are the same
 
bump the multiplier and then bump the core voltage when you get to a point where it fails to load or crashes
 
very good information in that thread,but the link is not working.

working with an unlocked chip is the easiest to overclock.

just raise multi and vcore till you get where you want or hit a wall,make sure you know your processors limits.

if you are using the stock heatsink do not expect very much as you should hit a thermal limit before you max your chip out.

do not go past 1.55vcore that is generally considered the max,lower is better.

try to stay under 60C at full load when you reach your desired clock speed,if you exceed that,lower your overclock until you get a better cooler.

Stock cooler.

I would like to get 4Ghz if that is possible.

Should I do all this from the Overdrive program ? just keep bumping the voltage and multiplier for all six cores until it is no longer stable ?
 
I have not used the over drive program,I would do it through the bios.

just start with the multiplier,start bumping it until it fails a stress test or crashes,then bump the voltage a little bit at a time to see if you can get it to run stable.

do that until you reach one of the limits,more than likely the thermal limit.

ok, sounds good. can you recommend a good program for doing stress testing ? thx
 
I would use intel burn test,do like 2 runs after you do each multi adjustment,when it fails or crashes start slowly bumping the voltage when you get the test to complete again start raising your multi again till it fails then adjust voltage a little more.do this until you hit a limit

once you get your oc to a comfortable level or one of the limits,start running the test for longer say like 20 runs or so,watch your temps during this time as well and be prepared to adjust voltages a little more to get the oc stable or to tone down the overclock if you start passing the thermal limit.

Nice ! Thx again for all the help folks ! :D
 
Dont use AOD, use the bios, the link i gave works fine for me, and you wotn hit 4.0 with the stock cooler, expect ~3.5/3.6 GHz on all cores, maybe 3.7, the voltage you will probably need for 4.0 will be too high for the stock cooler to handle

Indeed it is,It was throwing a database error when I clicked it as well as showing the entire link not just the "here" it shows now,I knew what one it was though :p
 
Ya, the link was unstickied on me, so it took a min or two to find it :D

OP- Any update on your progress? You also will want to raise your NB speed.

Bro just hold delete or an F key to get into your bios, then in the VCore setting on your CPU bump that up to 1.50000Volt. (That's a 100 pct safe setting for stock cooling) (it's most likely @ 1.3V sum-thing) Next take your multiplier from stock 16.5 and raise it to 18.5 so you will get all cores to 3.7GHz. Now since your chip has a Turbo mode (unlike mine), you have to find the setting in bios and disable that.

With the new voltage+multiplier settings you will be @ 3.7GHz 24/7 on all cores. Now if you want it to automatically idle down clock the multiplier when not used by a current program (like if you go to the kitchen to get a drink or something) then you want to use/enable Cool N Quiet in the bios which isn't a bad recommendation to save some electricity in those situations, I use it myself.

This should be a 100 pct stable 24/7 easy setting to get you headed in the right direction. After some time or if you go for a better cooler you can try 19,19.5,20,20.5,21 etc. multipliers until you find the most stable/highest clocks your CPU can handle and the temps you can handle.

Use CPU-Z and Core Temp to verify speeds and memory and core temp to verify all core temps are within TJ-Max.

Just for reference I've put 1.7 Volts on my AMD chip on air cooling and never ruined it.

Prime 95 either 32-bit if you have 32-bit or 64 if you have 64 let it run errors usually pop up in 10-15 minutes if unstable. If you can run it for 2 hours and watch temps in Core Temp and they never go beyond TJ Max that's a quick way to be 99 percent sure IMO.

http://files.extremeoverclocking.com/file.php?f=103
 
i WOULD NOT put your core @ 1.5v on the stock cooler, you will hit dam high temps (over 64c), i personally wouldnt want to run at 64c or above at all on my CPU, yes it is technically good until the ~90s, but AMD's "spec" is to 64c IIRC on the Thuban.

Teletran, its not goign to be the same as your Rana, the Thubans put a shit ton more heat, from personal experience with a Thuban and a stock cooler, dont put 1.5v into it.


edit: @ Teletran, a Rana does not = Thuban, 3/4 cores vs. 6, air cooling with what you have is probably better than stock cooling. Also, 1.5v is overkill for 3.7ghz on a thuban, that will need ~1.4v at the most....your Rana seems to be a shit OC'er if you need 1.4875v on the core to get 3.875Ghz....

Yeah but I'm 100 pct stable and with 18-52 temps on all cores you do the thermal risk assessment ;), your correct there is differences a Rana is a 4 core and a Thuban is a 6. HE should definitely be looking at his temps like I stated use Core Temp it's a beautiful program for that kinda thing and will show his TJ Max in the program, temps will go red if he goes over it also which is a nice touch.

Maybe your right maybe he only needs 1.45 or 1.4 to get whatever your trying to recommend.

For what I'm recommending 1.5 aint gonna kill his chip if mine does 1.7 no prob, I'm recommending the real shit, the real OC with 100 percent stability as long as his temps show good. And even if they go over AMD chips are made strong I've taken mine 10 degrees OVER TJ MAX no probs man.

I personally like putting more volts than necessary and going down later. Like on mine I started 1.65 then found out what CPU frequency works for me and where I like my CPU @ temp wise and frequency wise. When you boot out from BIOS your CPU will be idling and have low temps, only until you start running Prime 95, linpack, handbrake or Cinebench 3D mark Vantage/11 will you really get temps up anyhow.

Anyhow, yeah drama king it up on my posts or just get a stable high OC , whatever works. I KNOW what works so do you! ;)
 
Heck I spent more on my cooler than my CPU that should tell you where my interest is ;)
 
52c is safe, your also refering to 3 cores, 1/2 the amount that the OP has, do you have experience with the Thuban core? It runs hotter than the Rana's, even when yours is unlocked. Temps need to be watched, the stock cooler WILL NOT CUT IT FOR 1.5V.....as i stated you have something other than stock, 1.5v wont kill the chip, but it will over heat at that voltage, it takes a shit ton to kill a chip these days.

Take your knowledge and apply it to a scenario which you have experience, overclocking a 1100T is a ton different than your tri core Rana.......You go for a different method of OC than the majority of people do, most of us dont crank the volts to the absoulte max to find our "wall", we work volts and find highest speed at that volt and go by the temps. If you bothered to read the link I posted in post #2, then you would see it is an all around guide.....

that is a backwards way of overclocking.

Overclocking VIA bios takes some time. Amd over drive is nice for on the fly use it if you can, then you can hard set the values in the bios.

With thuban or amd x6 which ever you prefer is a short list of things to follow.

1. Keep Vcore under 1.5 volts with stock cooling. Your cpu temps at load should never go above 60c. Based on my experience with the x6 anything over 55c usually results in being unstable. The stock heatpipe cooler even with good case will not be able to handle 1.5 vcore. I was able to go to 1.4 vcore before my temps hit 55c and higher. My case is VERY well ventilated and have low ambient temps.

2.Leave cool N quiet on, there is no reason to disable it.

3.Turn off Turbo.

4.The x6 responds really well to Hyper transport bus speed increases. You can increase this by fsb, you may have to fiddle with the hyper transport multiplier. Keep in mind if you increase the FSB this will also increase the DDR ram clock. You may have to lower the memory multiplier if you increase the FSB a lot or you have sub standard memory.

5.Increase the north bridge voltage can stabilize a system.

6. To find the max for your cpu quickly, lower the mem speed to the lowest setting, increase the northbridge voltage by .1, raise cpu voltage to 1.450 then go to the mutiper work your way up in x1 increments. Once you reach your max you can do tweaking such as lowering vcore to see if it is still stable and remove the northbridge voltage increase etc....

Most 1100T will reach 4ghz with ease. 4.2-4.3 with a good chip. However some do not reach 4ghz.

Good points, I wonder what clock speeds he is running yet? What you say OP.

buying cheap chips?

Please don't troll 1.7v will fry things...they use that with LN2...

anyhow cwolf78... your not gonna get 4ghz on a stock cooler... 3.5-3.8 is about the best your going to get depending how fast /loud you want the stock fan spinning and on how hot you like your chips.

Turbo only sort of works on the Phenom IIs... turn it off when you overclock anyways.

I suggest grabbing a Xigmatek gaia and you should be able to get 4ghz no problem... maybe a lil more depending on how good of a chip you got. Tobit managed 4.2 and thats about all any chip will do.

Ha I didn't see your post initially, that's about exactly what I recommended him to try. At least someone doesn't think I'm to crazy. :rolleyes:

Anyhow I wanted to state that for my AMD setup NB Vcore Voltage modifying doesn't seem to do anything beneficial for me so I keep mine stock at 1.30000V. I find when I up my Hypertransport voltage from 1.3Volts to match my new CPU voltage, and speed becomes from 1800 or 2000 stock to 2500 OC'd, I have better stability when I match my Hypertransport voltage to whatever my CPU voltage is set @. So in my case i use CPUVCore and HYPT VCore of 1.4875 and 1.49 since those are the closest values to choose from. Just thought I'd put that out there, I have spent hours if not a multiple days combined tweaking my system, let alone my old Core 2 Duo and before that an AMD 2500+. Never blew a damn chip in my life either.

Good luck OP. Get back to us on your success, kk.
 
That is no where near what you recommended...

you said pump 1.5v into the chip with a stock cooler, quoted from you:
then in the VCore setting on your CPU bump that up to 1.50000Volt. (That's a 100 pct safe setting for stock cooling)
Click to expand...


Your values have absoultely no relevance since a Rana cannot compare to a THuban in values anywhere, they are very different. You also said let it go up to 70c, where as ebduncan said to leave it at 60c.


ebduncan's post has pretty much one of the better ways to go through it, though sitll dont like AoD (bad experiences when it 1st came out)
 
I got it to 3.7GHz at 18.5 multiplier in the Bios. How, and what speed, do I need to increase my NB by ? I saw that in one of the posts on here... that I needed to do that as well.

NB increase will increase performance but also tends to introduce instability....

try 2000 and then up it by 100mhz till its unstable... use OCCT to test the clocks... I recommend you try OCCT at stock HT first to make sure you are stable where your at.

normally anything over 2200 causes instability

you overclock ht by adjusting bus clock... so as you up that you will have to lower your cpu's multiplier to keep the same clock speed.
this will also adjust your rams speed so you will have to lower its multiplier as well...

alternatively... there are multipliers on the HT link that sets it against the bus... 9x should be default off the stock 200mhz bus... 10x will give you 2000 and 11x 2200... revert to bus clocking when the 200mhz jump isn't small enough.

Edit: reviewing my nb clocks from the past... as stewie is so far off from anyone else...
I have been overclocking G34 more than AM3 of late... and they have different ratings on those buses...

ok, so the NB clock and the HT clock are totally separate of one another ?

I will look at my BIOS again after work... I may even post some screen shots so you guys/gals can see what I am doing/not doing.

YES lol... Stewie was responding to NB clock and I to HT

2000-2200 for HT 2800-3000 for NB ...
NB is the IMC (integrated memory controller) so bumping that increases bandwidth for your ram...

you may not be able to get past 2600 on your nb clocks...

ok. The NB clock settings seem easier to adjust than the HT... I will post some screen shots if I get to confused.
 
Yes, NB should have its own selector in your BIOS, just leave the voltage for it on auto. Aim for 2600 to start, then possibly 2800

I was responding to the northbridge clock,was posting from work on my phone so I made it short,I thought 2.8-3ghz was the norm for NB overclocks on the phenom II,mine is currently running at 3.8 on the core,2.8 on the northbridge and stock 2.0 on the HT.

I was under the impression that HT clocking was not all the beneficial,I could very well be wrong though as I have not delved all that deep into it.

If you do start overclocking the HT be sure not to set it any higher than your NB speed.

when I first started OCing this chip I did it backwards and was having all sorts of stability issues,It took me a while to figure out what I had done,lol.
