my phenom 965 c3 clocking

Nice work gareth. It'd be interesting to see how close you can get to 4.00GHz.

I also agree about the testing methods. It shouldn't be forgotten that while a processor isn't crashing at a certain speed it's not entirely stable. Certain operations could well be producing erroneous data and processor's performance may not be as good as an otherwise "stable" overclock at the same frequency. I might appear as though I'm being petty, especially for uses such as games but for those who run folding@home say, I'd much rather send those projects back without errors.

Since we're playing the IBT stable game.

4ghz with 1.525v.

i ran IBT for about a minute , it didn't crash but i stoped it because the tcase temp was going over 58c which i wasn't to happy about.

how much better is the Thermalright TRUE Copper CPU Cooler than a Thermalright Ultra-120a? also is it to heavy when the case stands?

 

[Martini1991]

LOL.
Like I say, these Phenom's like the heat, IBT is unreliable due to the heat it causes, which causes instability..
AMD CPU's work differently to Intel's.
3.9GHZ on stock volts *** ?

Why do you guys run Intel burn test on an AMD chip any how, surly the clue is in the name .....?

I use Prime and OCCT and the AMD overdrive test is also sufficient....

Just curious thats all..

Intel burn test is the quickie to find out if your system is fully stable..

Compatibility:
Works with Intel(R) and AMD CPUs. Tested Intel(R) Core 2(tm) Quad
Q6600, Intel(R) Pentium(tm) III 550 MHz, AMD Athlon 64(tm) X2 4200+,
and AMD Opteron 165 (Working with AMD processors since v1.7). Also
tested on AMD Phenom II X4 940 Black Edition.
Tested on Microsoft(R) Windows XP Professional SP2/SP3, XP Professional
X64 Edition SP2. Tested on Microsoft(R) Windows Vista(tm)/7 X86/X64
by many awesome users like yourself
Benefits of using Linpack:
1. More accurate than Prime95 Small FFTs/Blend (under x64 OS).
2. Takes less time to tell if your CPU/RAM is unstable than Prime95 (usually
something like 8 minutes Linpack vs 40 hours under Prime95).
3. Use the same stress-testing engine that Intel uses to test their products
before they are packed and put on shelves for sale.

AMD overdrive test is crap tbh.

They're near identical architectures there are no "Intel only" or "AMD only" tests, both CPU's are designed to execute x86/x64 code as fast as possible.

All IBT does is uses your CPU for what it is designed for, the heat is a byproduct of your CPU doing its job, the same way you sweat when you're working hard opposed to sitting doing nothing.

 

[Martini1991]

AMD CPU's have a far lower tolerance to heat than Intels, this results in IBT being unreliable for AMD CPU's.

mate, linX and IBT use the same coding. both programs uses the cpu to the max.

an extra 4-5c shows you that the cpu is using to the max, it's hardly unreliable

IBT


LinX

The unreliability comes from overclocking a Phenom to 4ghz+ though not from IBT.

As you've proven to reach 4ghz Phenom's require too much voltage and run too hot causing them to become unstable, whereas most i7's do 4ghz on 1.25-1.3V. i7 is indeed designed to run hotter which is just as well because they also have Hyperthreading which results in even more heat/load than a standard quad.

 

[jms198]

I second everyone who says to use stability tests such as IBT. Regardless of whether its AMD or intel you are still runing the same software on either at the end of the day.

I tall ya as soon as I get a sniff there are PhII 550 floating around based on the new revision silicon I'm breaking the piggy bank!

The 555 should be out soon.

how much better is the Thermalright TRUE Copper CPU Cooler than a Thermalright Ultra-120a? also is it to heavy when the case stands?

also shell i keep it at 3.9ghz 1.475v or drop down to 3.8ghz 1.425v?

 

[gareth170]

update

i've got 3.8ghz stable on stock voltage.



the nb was holding it back so i droped it back down to 2000mhz for now and kept the voltage at 1.15v... once i've the max core clock , ill start doing the nb.

 

[Martini1991]

Impressive mate.
Try for 3.9GHZ on stock?
I still have no idea why our C3's have different stock volts lol.

 

[gareth170]

Impressive mate.
Try for 3.9GHZ on stock?

3.9GHZ fails. so 3.8GHZ is max for me on stock voltage

 

[Martini1991]

I might just run my 965 at 3.9GHZ with a 3GHZ NB tbh lol.

 

[gareth170]

tomorrow ill get 3.9ghz stable on low voltage hopefully on 1.425v then sort the nb...

now i'm gonna play dirt 2.

 

[Martini1991]

I'm going to make the most of the cold, then I'll give you an "overclock" off

 

[gareth170]

well you're got a slightly better chip due to the slightly lower vid. so yours will do about 100-200mhz extra than mine.

my house is quite warm, i guess about 21-23c. so my cpu temp is not to bad...

 

[Martini1991]

Unless my room's cold, and because my mam keeps the heating on, I can't seem to do 10 runs of IBT anymore lol >.<.
