Mild Opty Overclock

[pentiumobile]

Yesterday I got tired of the stock speed.

So I hit 2.6 at (289x9)?My PC Booted?Ran Super Pi 32M?but frankly I don?t trust me, b?cos this is my first time.

To be straightforward I still don?t get all the:

?Timings, HTT?Dividers?Isolate?Tweak?Tweak?bla bla bla?

I?m not that hard to please so I don?t want the last ounce of MHz out of my CPU.

Bottom-line.

2.4GHz

That?s perfect for me.

My cheap RAM Hold?s me.

Corsair ValueSelect 2GB
Epox 9NPA SLi
Opteron 165 0546 MPMW

????????????????

267 x 9 = 2403MHz

150Mhz Memory Divider --> DRAM Freq = 200.25MHz (Perfect For My RAM)

But my confusion is with the HTT bcos I cant hit the 1GHZ.

What can I do to put everything on order?

You tell me if I?m using the right approach.

 

[Smartazz]

That's the overclock I was looking to get, the diffrence between 2.4 and 2.6GHZ might not be that dramatic.

 

[pentiumobile]

To tell you the truth...I think that 2.4 is ideal...

I just put it @2.4

I undervolted the Vcpu by .07V, Bcos my Epox bestow too much juice..

My CoreVolts are around 1.35-36

My Iddle Temp is 39 (My Room Temp is 29.5C)

You have to remember that temp's set out linearly so if My Room was at 22C My CPU will idle at low 30?s (28C at 1.8GHz@22C Room)

The bad thing is Voltage. Remember that Higher Voltages ?pulls? electrons easier and its collisions fritter away more heat. I think V performs ?squarely? on temperatures, so a small rise can fry your chip.

So what should I do now to see if my system is stable at this???

Priming??


UPDATE:

I just found out that the command rate of the memory is at 2T...also the automatic timings are at...

PLEASE HELP ME WITH THE TIMINGS

MEMORY TIMES

 

[EagleEye]

man, i couldn't get 2.6 with my opty, congrats. and for the memory timings, how many sticks of ram do you have? If you have 4x 512 sticks, then it can only run at 2T settings.

 

[pentiumobile]

I got 2 1GB.

I never tested the ram...so i go with the "Bias" that it can't go further than 210.

Tell me something:

When you say you cant get to 2.6 it means that it doesnt boot???

 

[pentiumobile]

36s at Super Pi 1M

Stock 46s

 

[Thor86]

For any real-world performance boosts, running the max cpu frequency would net you the most performance gains. Then, you should try and aim for 200+ on the memory with the highest cpu speed.

I'm not familiar with that board, but you should try and use the lowest memory divider possible and test your max cpu overclock, and use Prime95 to test cpu overclocks. There are tonnes of threads on how to use Prime95.

I'd also recommend you back up your data before doing any of this.

-edit typo-

 

[pentiumobile]

I?ve been priming for 20 mins...

I don?t really want all the power now 2.4 is ?more than more? for my fist overclock.

I?m on summer vacations so next ones (december) i will go for the 2.6

Right now I opened Super Pi with Prime and OCCT

CPU 100%Temps 46C
RAM 2+GB used...
I also will put now one SQL backup that spend almost 1GB to completely saturate the system.

I know that with air conditioning I can lowet the CPU to High 30's Low 40's at load

Jeez, it's not like driving. Going at higher speeds won't kill you, though it seems like you think it will.

There's plenty of warning signs before you damage your cpu right?

I don't think I've ever heard of anybody damaging their CPU by OCing, but as always, YMMV.

What's the highest temps for load that these optys can handle? 60 degrees celcius?

 

[Howard]

Probably higher than that, but I don't know the exact figures.

I have. Someone lost one of the cores on his Pentium D 920.

Well, there's a first time for everything.

 

[Lord Banshee]

So i am confused?

You went to 2.6, got scared and went to 2.4?

My Opteron can do 2.4 at stock volts which looks like yours can, and 2.6 at 1.475 volts. My opteron has yet to hit >=60*C and i don't have any high CFM fans in my machine.

I've known/seen many people who've lost their Celeron 300A back in the day because of overclocking. It was working at 450MHz but then stopped working stabily, even at stock speeds. That said, just don't jack up your voltages significantly and run stability tests like Prime95. I'm personally running my Opteron 165 @ 2.55GHz.

I believe that was stetvy (spelling there?) idn, im too tired to looks up names right now

I am playing BF2 On my 7800GT...And I can Hit 1600x1200, 2xQAA, 16xAF and "Quality Settings" at more than 60FPS (From 60's to 90's depends on effects)

I really dont need to push it harder...AND...I want to leave some "extra speed" for the future.

Do you think my PC is "stable" since I played BF2 at those settings from 8PM to 3:30AM?

What about my HTT...is set to AUTO.

What should be it speed?

Since I got 267x9...memory@150MHz

 

[foodfightr]

I have my opteron 165 running at 1.8Ghz @ 1v and 2.7Ghz @ 1.36v and rightmark will automatically switch between these two configurations to keep the temperature down when the extra juice isn't neccesary. 100% prime & 3d stable.

Here is what I'd do if I were you.... test your opteron at stock voltage and gradually increase the HTT and prime for 10-20 minutes minimum. Repeate this until you need more voltage, then try to slowly add voltage until it is stable.

I'd say 1.35v-1.4v is very safe, 1.4v-1.5v is moderately safe, 1.5v is risking it a little and 1.6v+ is suicide. Keep your temperatures under 60^C.

Also if you posted your stepping you may be able to get an idea of what your chip is capable of.... On the chip itself (ONLY HERE) it will say CCBWE 0xxx xxMW, for example CCBWE 0550 UMPW. Post this and I might be able to shed some light.

ALSO!!! Very important... set your CPU Multi to 9x (not auto) and your LDT Multi so that (LDT Multi * HTT) <= 1000.

that is more the gpu than the cpu giving you those fps. you would probably get the same fps if you kicked it down to 2GHz...

Honestly, if you have to raise your voltages past 1.5 and not get a decent overclock, you have a crap Opteron. I have hit 1.55 volts before on my old Opty 170, and it could only yield 2.66 ghz. Temps were skyrocketing into 55 for load, and definitely not good. It took me like 1.7 volts or more to hit 55 for load on my old 3700+.

Voltages shouldn't be an issue in Opterons because the general rule is to keep them below 1.6. You won't be going that high on air because temps will be through the roof.

My own Opty is clocked at 2.5 ghz (250 x 10) and I have my ram running 250 3-3-2 according to the OCZ specs (I can't get CAS 2.5 like Anand does), and it's a smooth running system.

That said you do have a much better opteron than I do. I have to crank up 1.4 volts to keep it stable. Even though I primed 10 hrs stable at 1.4, I run my opty at 1.425v just in case. Also I keep a little more air cooling on than I did at testing stages. Anything to ensure 100% stability =)

Yeah, but what are you in-game video settings?

 

[AxemanFU]

I may have this wrong, but on my opty 165, reducing the HTT speed between the proc and northbridge allowed me to get a higher overclock without overvlocking the HTT frequency.

I'm not 100% sure, but I think as you increase your proc speed, your HTT may increase proportionally with it, so dropping it's multiplier from 5x to 4x, or 1000mhz to 800mhz, gives you more overhead. Say 1.8Ghz to 2.4 Ghz is 33.3% increase. Your HTT from CPU to NB will also increase 33%, to 1333 Mhz if you dont drop the multi from 5 to 4. If you drop the multi to 4, then it is only 800x 1.3333, or 1066mhz, much less strain on the HTT link. I think this is how that works, anyways.

On the memory side, with the fixed 9x multi, you have to drop your memory ratio as you increase proc speed or you are forced to seriously OC your ram. for example, at 1.8 you might start with 200mhz mem setting. When you o/c to 2.4Ghz, and leave the ratio setting at 200mhz, your ram is running actually at 1.333 x 200 or 267Mhz. If you drop the setting to 166 or 150 or 133, you get acutal mem speed of 221, 200, or 177MHz respectively. These two tweaks, the HTT and memory combined, will get you get the proc speed sky high while still keeping the HTT interface to northbridge and ram FSB speeds tolerable. Some maty complain you lose perf by tooling back the HTT speed, but the proc can't use the full 100Mhz bandwidth for the most part anyways, so you lose only a few % performance by dropping to 4x (800hmz) or even 3x (600mhz) even before you o/c the proc and bring it back up.

I still have the retail cooler on mine, so I havent tried for 2.6 GHz yet. My cheapo asrok 939 sataII board on the other hand seems to love this processor.

 

[pentiumobile]

Thor86:
My game settings? Everything on HIGH.

AxemanFU:

I just figured two things?

1)My LDT was set to auto, now I put it to [267 X (3 LDT) = 801HTT]

I am very far from the 1Ghz.

Does that affect my performance?

Because now I Ran SuperPi and it did 35s (before 36s)

They say that HTT basically is a ?highway? and that even if you put ?16 lanes? to 8 cars It won?t do anything. Since they can?t go faster.

2)I changed the memory from 2T to 1T

I just did the ?monkey see..monkey do? Bcos I don?t have an idea of what the ?T?s? are for.
