just prime95 is fine. There is no need to run all of the stress testing programs, just one for at least two hours with a screenshot for proof.

i suck at this :/

nice
I agree raising the NB will give a nice performance boost.
your volts and temps are reasonable though it would help to know the room temp
after getting NB freq up and stable try loosening up ram timings and going for 1600mhz as long as that is DDR3-1600 ram
also adding a second fan preferably same model to the 212 in push pull will really help with temps

 

[ocmusicjunkie]

Very nice OC with the 6300... I keep looking at that processor and wondering if it might be worth picking over the 8350 whenever I upgrade the smaller of my two cases. That sort of performance at 95w instead of 125w would certainly make cooling a lot less problematic.

Personally, I would just keep bumping up the reference clock in small steps until you reach the limits of stability with all else left alone. That way you would have increases in equal measure all the way across the board with CPU, NB, HT and RAM frequencies. Even if you only got to 225 from 220, the combined effect would be fairly significant.

Deadboy, I'll hop over and check out your post now.

yeah I actually do hafve a 2nd one..but my fan bracket completely broke and I can't find any clips or brackets for replacement without buying a whole new cooler...would an H80 get me any lower temps? they have them right now at microcenter refurbs for like 57 bucks...thought about trying it or the enermax ets-t40...i hear that that cooler gets even lower temps than the 212 evo for less money

 

[king smp]

hear good things about enermax
me personally at that price point I would go with a Antec Kuhler 620 and add a fan in push pull
in benches the Kuhler 620 in push pull gives a H100 a run for its money and is equal or better than a H80
the 620 has been known to drop to $49.99 in Best Buy
only complaint I have is mounting it is a little bit tough
I run the 620 with two Scythe Ultra Kaze 120mm 3000 rpm 133cfm fans on a NZXT LCD fan controller
total cost was $100 and works good for me
my Phenom x 6 1100T Black Edtion OCd to 4ghz 1.55v doesnt go over 60c in a 80F room (I have two rigs folding at home and only have AC window unit fan intake pulling in cold winter air so it gets hot in here)

ive actually tried the 620 but it was on my old phenom 965 BE...i guess i either didnt get it flush mounted or was expecting too much out of it ..and yes...that stupid twist mount water block was not very friendly to me..but if that would be better than what i have then maybe I'll try it again...but at 57 dollars would the H80 be better for what I have? its regularly like 90 bucks or so...and when i thought about buying a friends i hooked it up to my machine in push/pull blowing air out the back and it was pretty decent..just loud as all get out even on medium...i thikn it may have had a faulty pump or something. ? thanks for the advice

 

[king smp]

my apologies I misread that post and thought it said H60
at that price jump on the H80 definitely
but be aware that self contained water loops dont perform like custom water solutions
they are equal to about a really good air cooler
carefully read this article

[ocmusicjunkie]

Nice OC... I've always wondered if OCCT was more difficult to pass than other programs. All it seems like I see is P95 stability screencaps....

As far as a newer version, you're fine. I bet that this is actually a case where someone forgot to go in and insert the proper name into the software revision. Regardless, the software doesn't need to recognize what actual hardware you are running to function, it just needs to read the temp sensors properly, which I've never had OCCT appear to fail at. Actually, version 4.1.0 is the ideal release if you can still find a download link. It actually has full GPU monitoring capability along with all the features on 4.3.2. I don't know if there is support with the newer release for Nvidia cards, but I've proven it just doesn't detect any 6-series Radeon card. Plus, the older version doesn't have the donation screen each time you start it up...

 

[clintwilks]

I've used P95 much more than IBT or OCCT...before I saw this topic I read a few articles that asserted the idea that IBT was a much better tool for stability than prime95 and that 10 passes of IBT would equal to about 12 hours of Prime95. I can say first hand, however, after first hand research and trial/error, this is definitely not the case. Afterward I was backed up by about 10x more articles saying the exact opposite.. (that Prime95 on blend with all cores working and/or OCCT were much better gauges of stablility...where IBT is more of a heat gauge than anything else.) As for myself, I can pass much higher OC's in IBT on HIGH stress level 20 passes ++ than I can on either P95 or OCCT for 2 hours.

really nice OC and not taking anything away from that but I would personally sacrifice some of the CPU clockspeed in favor of a higher NB and higher ram speed
you need to look at your system as a whole
like a series of waterpipes passing water or data through
that NB can be a major bottleneck in a system
doesnt matter how fast the pump (CPU) is pumping if the pipes (NB) cant flow enough water or data
also getting up your ram speed or the well the pump pulls from will help too
having one part of the system cranked up with the others running slow will cause bottlenecks

nah man i appreciate the info..i put this here for info on how to get it faster more than any other reason anyway because I've only had this chip for less than 2 weeks now...still dont know very much about it. :/

 

[king smp]

it is a really nice OC but remember the system is as fast as its slowest part
if you can get your NB and ram speed up higher and keep that CPU overclock that is great
remember the NB is a major data bus that the CPU communicates with the rest of the motherboard
going from 2200mhz to close to 3000mhz in NB speed is worth losing some CPU speed in my humble opinion

quote
"When you overclock your CPU, the higher you go the more likely you will need to stabilize the CPU-NB. What do I mean by this? As the CPU increases its speed to calculate data, so must the speed of which the CPU communicates with other components on the Motherboard: chipset, memory, etc. Let me take the classic example of a 4.0 GHz 940BE and its CPU-NB. If you were to leave the CPU-NB at 1.8 GHz stock then the data calculated by the CPU would create a bottleneck and thus resulting in errata errors or CPU errors. So in order to balance these speeds a CPU-NB clock of 3.0 GHz would be needed. In most cases of high OC’s that result in crashes; the CPU-NB is usually the culprit."

your CPU is at a good OC
try raising your NB and ram speeds
get your ram up to 1600mhz CL8 or CL9 with a 1T command rate
get your NB as close to 3000mhz as you can

a fast motor in a car is nothing without a good transmission and rear end

motor = CPU
transmission = Northbridge
rear end = Ram speed

I love analogies

 

[ocmusicjunkie]

King- that post was really insightful and definitely true. I'd actually make a case for the idea that you often don't need to trade CPU speed in exchange for NB speed. In a situation where the NB is either untouched or barely OC'ed, I think there is a real potential to find the first destabilizing factor will be the NB lag. Removing the thermal considerations, which may be the one problem that would be compounded by raising the NB frequency, there should actually be a higher ceiling for the processor. Interestingly, while everyone talks about 2T being the more stable memory setting, I have never gotten any of my peak OC figures without being set at 1T with the memory. The theory had been one I subscribed to for a while, but your post reaffirms the idea that bottlenecks can prevent stable overclocking of a given component.

 

[king smp]

well this is the settings I set for a daily OC on my 1100T

CPU 200 x 19.5 = 3.9ghz
CPU voltage = 1.53v with %50 LLC so really my volts stay between 1.47-1.52 generally
CPU-NB frequency 2800mhz
CPU-NB volts 1.23v
Ram - stock DDR3-1600mhz 9-9-9-27 1T
max temp 58-60c in a 78F room
idle temp - 37-40c in a 78F room
CPU cooler - Antec Kuhler 620 closed loop LC with dual 120mm Scythe 133 cfm 3K rpm fans

I have had the 1100T stable at 4.1 when the room temps were lower and I know with some tweaking it can hit 4.2 ghz stable but I think my 4+1 phase mobo VRM is limiting me

I have had it boot into desktop and run Cinebench 11.5 at 4.4ghz but crash right afterwards so I think if I can make it into the desktop at 4.4ghz I can get 4.2ghz stable

just limited by VRM and heat right now

sorry for rambling LOL

^_^ need a good water loop...i want 5GHZ O_O anyone tips on how to get there???

 

[clintwilks]

or if anyone can tell me how to get my nb up to 2400 or above and keep stable that would be great also !!!!

 

[truegenius]

raise cpu-nb volts to 1.25v and raise nb to 2.6+ghz

my this experiment backup your statement

overclock 1 (on 4 cores only)
cpu :- 4ghz (16x250)
nb :- 1.25ghz
ht :- 1.25ghz
ram :- 1666mhzcl9
stability test via IBT :- failed after second result (showed that my system is unstable)
total computation power :- ~43 Gflops

overclock 2 (on 4 cores only)
cpu :- 4ghz (16x250)
nb/ht:-3ghz (12x250)
ram:-1666mhzcl9
IBT:- stable even after 3pass (it was heating up so i didn't tried more passes :/ )
~50Gflops

 

[king smp]

funny thing is that I dropped my OC down to 3.8ghz
what I did was set my multi to 19
set my volts to 1.5v on CPU (because of LLC it varies between 1.408 and 1.504 and stays around 1.44v
NB is at 2800mhz with volts on auto
ram is at 1600mhz 9-9-9-27 1t
all other settings are on auto

I have had it folding at home for three days straight so all six cores have been at 100 percent for three days
temp is 54c in a 72F room


so I think today I will play with getting it a little higher
hoping for 4ghz

not sure about the rest of the info this is my first over clock ever, only thing i changed was the core speed and the voltage to 1.45v, not sure if thats too high or not what do you guys think? my max temp was 45*C really want to get it to 3.8ghz as I got prime 95 to run at 3.8ghz 1.475v for around 2-4 until i woke up and seen that i got a blue screen

I say go for 3.8Ghz yologelo, you have the temperature and voltage headroom so you might as well try.

 

[king smp]

raise your NB up
NBs whould be set at 2600 or higher on these AMD cpus

and definitely raise your ram up
1066mhz is way too low

@ yologelo -what is the stock speed of your ram?

My corsair vengeance 12GB 3x4gb just arrived and I've just fitted it aswell i think its running at 1600 dual channel and the other on 964 or something cant remember. When I did the printscreen I had 4x2GB crucial 1066mhz dd3 rams which I now replaced with the vengeance.

I got the 12GB because i got it a lot cheaper than the 8GB but I'd probably take out one of the stick so I can run on dual channel only what do you guys think?

would you mind explaining what NB, I still have a lot to learn xD I've manage to get my pc now into 3.6ghz with 1.375v so thats a lot better than 1.45v havnt tried prime 95 but manage to play bf3 on ultra without a problem since I have a crossfire x 6850's

 

[yologelo]

Will try but I'm not sure if it's worth it I usually just use my gaming pc for bf3 and such and I'm not sure if its worth to sacrifice the temperatures, go for it or not?
