Hello all, I am new to overclocking and all and I have a couple questions that I am hoping you will graciously help me with. I have downloaded Prime95 but am not sure how to properly set it up to run a test. I would rather have someone walk me through it if at all possible. I did not sign up on their GIMPS site, do I have to do that? If this is in the wrong topic please feel free to move it to the appropriate section. I would appreciate any help I can get to make sure that my system will be stable.

Wanted to update my signature to reflect my systems specs, but I am unable to get it all to show up, I am guessing there is a character limit.

I am not an expert but will share what I know

do not need to join GIMPS
should have option for just stress testing
blend test is good for memory testing
small ffts is good for testing freq of CPU
large ffts is good for heat testing
some say a 24hr stress tested is needed
but I have read that really 2-3 hrs of stress testing will enough to make sure you are stable
i looked at your cpuz
seems to me you would be better off lowering bus speed from 230 and raising your multiplier
since it is a BE using the multi is the way to OC

but to be honest with you I am a novice OCer so hopefully some of the more experienced guys will see this

To be honest the Mobo that I have, has some dipswitches that allows me to OC 10%, 15%, 20% increase to the FSB. I have it set to the 15% right now and it changes it automatically for me, but I am unsure how stable it is. What I am going to do is change it back to default before I got to bed here in the next 30 minutes just to be safe until I get more feedback from people here. I appreciate the quick response King Smp and like you hopefully some other people will be able to shed some light on things for me.

Sorry for posting in the wrong section, I thought maybe it should go here since I have an AMD system. Anyhow I used your link and started a new thread again you have my apologies.

It is a interesting sharing..........

Which would you say is good to test the stability of the system small, large or blend? It also has Number of torture test threads to run what should I put in there?

 

[king smp]

it would be better to post a new question thread regarding Prime95
this is just for posting OC results
I didnt know that myself

Just for fun, here's a laptop overclock. I could have got it a couple of hundred Mhz faster, but I wanted an overclock which I could keep running 24/7 without worrying about temps.

Cpu: A8-3500M
Name: elel
Stepping: 0
Frequency: 2000
ref*multi: 100*20
CPU voltage: 1.00V
CPU-NB: auto
NB frequency: auto
NB volts: auto
RAM: 6 GB 1333 Mhz 9-9-9-24 @ 1.5V
Motherboard: HP 358B
Cooling: builtin laptop cooling
OS: Win 7 64 bit

The stress test screenshot (edit: realized that prime95 does tell you when a run started 😛 new screenshot with all threads scrolled down):

I'm actually pretty impressed by what this CPU can do. That's a 33% overclock (1.5 to 2.0 Ghz) with a 3.2 % voltage drop (1.0375 to 1.00 volts). The temperature under load is 69 C; if I drop the multi to 19 I can drop the voltage down to 0.9625V and have temperatures less than 65 C. Tweaking done with FusionTweaker 1.0.5, since my motherboard offers no overclocking options. The funny thing is that, at least when using this utility, there seems to be no lock at all on the CPU multiplier. I bumped the turbo up to 3 GHZ in steps and ran superPI in a single thread; the time dropped every time I increased the multiplier, and this part is only supposed to go to 2.4 Ghz with turbo

Didn't break 49c so I may try 4GHz with max CPU fan at some point. I had 1 caveat of core 6 failing at 1.35 volts in an earlier run.

Better shot of the prime95 run.

 

[king smp]

really nice work elbert
having a 960T at 3.7 on six cores is really good IMHO especially with a low voltage

 

[donkeywax]

hi elbert
i would love to see how fast you can actually make that chip go,
the person on top of stable overclock table is running a thuban at 1.56v,
ive got a phenom 965 deneb and i chickened out at 1.5v even though my temps were fine,
people seem to raise voltage higher on thuban chips than they do on deneb,
does any body know safe maximum vcore voltage, phenom ii 965,
i would love to push mine little harder get into the yellow band at the top of the table,
i mangeded to get my 965 to 4200mhz but core 4 failed after 2 hours and i cant get it stable,

 

[bardacuda]

Hey all. Just upgraded my ol' Athlon 640 to a 1090T last week. Seems my nForce board won't be getting a BIOS update for AM3+ CPUs and availability of AM3 processors is dwindling so it was now or never if I wanted to max out this socket. Anyway did a little playing around in the BIOS and here's what I came up with:

Cpu: 1090T
Name: bardacuda
Stepping: E0
Frequency: 4000MHz
ref*multi: 200*20
CPU voltage: 1.424 - 1.472
CPU-NB: 1.25
NB Frequency: 2800
NB Volts: 1.22
RAM: 4GB 1600Mhz DDR3 8-8-8-24-1T @ 1.65V
Motherboard: MSI NF980-G65
Cooling: Hyper 212+
OS: Windows 7 64-bit
GFLOPS: 76.9

So there you have it. Voltage and temps are about as high as I am comfortable with and I can't get a stable LinX run if i turn the voltage down a notch. I almost had a stable run with the NB Freq at 3000 and NB volts at 1.23. It was going for an hour last night before I went to bed but when I got up it had rebooted 😛 That's OK though cuz MCP temp (southbridge) was up to 71­°C and CPU was peaking at 56°C which is kinda above my comfort zone anyway.

For some reason cool n' quiet doesn't seem to be working at this freq but it was at 3800. Think I'll set it back down to 3.6 or 3.7GHz and lower the voltage as much as i can and leave it there till it feels too slow, cuz I want this puppy to last a while.

This is my legit OC. My 3.48x OC ended up BSOD while running 3D Mark Benchmark. It worked fine after a voltage bump, but then myPrime95 temps hit 57C and I want to stay below 55C.

So 3.4Ghz it is:

*update* bumped it up just a bit...

Cpu: 1045t
Name: Z1NONLY
Stepping: PH-E0
Frequency: 3401.6
ref*multi: 252*13.5
CPU voltage: 1.344 @ full load
CPU-NB: auto
nb frequency: 2519.8
NB volts: auto
RAM: 8GB 1343 9-9-9-24 1.5v
Motherboard: Gigabyte 990FXA-UD3 rev 1.1
Cooling: Coolermaster Hyper TX3 (w/2 92mm fans) +5 120mm case fans.
OS: 7 64-bit

Can't fit a big HSF in my case so I ended up using negative offsets for the V-core until I was able to keep my temps under 55c peak.

At full load the voltage is 1.344v. I left C1 enabled so the voltage drops when not under load.

I was also able to keep my turbo core enabled. But I had to back the fq down to 3780 with these voltages. (BSOD @ 4000)


* As of 2/26/12, I think I have maxed this thing out with my current cooling.

For the record I am using a negative V-core offset of -0.075 with my MB listing it as 1.35v (I guess it "droops" to 3.44v under full load.)
Max temp at this Fq/voltage/cooler is 55c after two hours of prime95.

I attempted to lower the voltage another notch and make another run at the fq, but it just wasn't stable with the lower voltage. I even tried to "pad" my Novabench numbers by bumping the multiplier on my turbo core one notch....BSOD. I could probably bump the FSB a little more, but I want to keep the HT link close to 2k.

So unless I get some better cooling, (and bump up the voltage) this is all she has ATM.

Well, I'm new to overclocking but I can play skyrim and dirt 3 for hours on end with all the settings cranked to ultra @ 1920x1280... Can't Prime it accurately cause it heats my processor too much. But for just amazing gaming.... It works 😉

*Voltage Set
Running Prime 95...

 

[king smp]

I agree with Mal
good OC
and with a Hyper 212+ you should have good CPU cooling
so it makes me think either the 212 isnt seated or pasted properly
or your case cooling has an issue
what is your room temp?

 

[saint19]

Or the "Auto CPU Voltage" is bad and you should use manual instead of auto.

 

[saxtontechsolutions]

I guess I should have said that I can game without my multiplier dropping, If I prime 95 test it I can let it run for hours on end, but my multiplier will drop to x8 and x4 whenever my CPU temps get to 53C. 4+hours prime 95 no errors.

I don't think it counts if you can't hold your clock speed under stress testing.

I would also worry about the longevity of my chip if I ran a 24/7 OC that did that under stress. But we are all OC in this thread, and so we are already "pushing" our CPU's to some degree, so I guess it's a matter of our individual "comfort zones".

 

[Z1NONLY]

At least you are on the chart. I'm starting to think my OC is too weak to get added to the stable list.

*hint* *hint*

 

[Z1NONLY]

I posted all the info and screen shots about 8 posts up, on this page.

1045t @3401.6 on a Gigabyte 990FXA-UD3 rev 1.1.

It's stable. I have experimented and found it good up to ~3900 with a small voltage bump. -But I can't fit a big cooler in the case and don't want to go with liquid.

So 3.4 it is.

a low profile 92mm is a possible option
something like this
http://www.acousticpc.com/zalman_zm-cnps8000a_ultra_low_profile_quiet_cpu_cooler.html
about $35 USD on Newegg

there are many others
check DBA noise level and CFM plus reviews if possible
though I am okay with some fan noise so I look for higher CFMs

Thanks, but I'm already using a Coolermaster Hyper TX3 (w/2 92mm fans)

If I ever get the urge to do a seriuous OC, I can always just buy a bigger case cut a hole in the side pannel of my exiting one. (Then go with a 120mm HSF.)
