re: Overclock List & Discussion Thread

@LFC_fan: AFAIK AMD cool n quiet is quiet inefficient on the older amd models like the 4400+ and hampers OCing unlike intels speedstep...you will just have to disable it...alternately u may try a bios update to see if it helps

@asigh: he has an amd procy so no FSB and ocing is a totally different process and afaik multiplier is locked on non black edition procys

Then how does one OC it. With both the FSB and multiplier locked..?

re: Overclock List & Discussion Thread

Honestly cannot be bothered to remove the cooler of the GPUs. They can easily sustain temperatures past 90C. (That is why we pay so much for them). And I doubt I will need to OC. Am satisfied with the Xfire.

You planning to dismantle yours..????

I m going to buy either HD5850 or HD5870 for Phenom 2 940 & put my GTX 260 in to Intel one may be Q6600 from my friend .

I am going to dismantle the GTX260 , cause its comes with 3rd party cooler which i dont like most

re: Overclock List & Discussion Thread

@ asigh AMD proc's have had an integrated memory controller since a long time, something which Intel has only since core i7. So, AFAIK, just like you OC the core i7 920, which has no FSB and no unlocked multiplier, same way its for the AMD proccy's. I have not oc'ed my proc yet so I can't help you with this much as of now. :)

It would be better to mate the 5870 (if you get it) to the high-end i7s. There are issues of CPU bottle necks. Though even if you use a Phenom 2 940 or P55 i5/i7 or even a high end Quad you will get phenomenal performance -- but you will not extract all the power from the 5870. And is not that..what we all want. To squeeze every drop from our systems..and then take it a bit beyond.

Ok...did a bit of research. For the X58 chipset unless you have the extreme edition i7s the multiplier and FSB is locked. The QPI has to be changed, and that is done using the Base Clock. BCLK. Once the BCLK is changed it moves the QPI speed respectively. But voltages and RAM timings can still be manually changed -- if the chips need extra power.

Could anyone place the procedure here for AMD chips. Or if they want they can make a similiar chart like have (use Visio). Else I can make a chart for AMD chips - if someone can tell me a detailed method.

I got this Phenom 2 940 cause some day i wud sure OC over 5Ghz , cause Phenom 2 940 Hold the record of 5.5ghz using H20 .

All i need is vantage points any ways i should touch 45000 to 50000 in vantage mark . GTX 295 3 ways is to costly for me & GTX 295 i cant OC much ! i need to wait until HD5870X2 should be launched

Till now 44750 vantage mark is the Highest scored with Phenom 2 on 6.8Ghz with HD4870X2 - it wud be worth to get HD5870X2 , so i can manage to save to money for Higher end proccy .

Anil - i dont think Corei7 920 compared to Q9550 & 940 dint do much performance in OCing , Though i7 920 cannot be pushed over 4-4.2 even with higher End cooling !

Its not about the OCing factor. Its how fast the CPU can feed the data to the GPU. Prior to this it used to get bottle necked due to the North Bridge. The QPI has corrected that, so more data can flow via tha x16 channels.

hey guys m new to overclocking not much of an overclocker have the following spec

not a powerful system IMHO but it suffices my need.... well just installed Sunbeam Core contact Freezer 120mm n have got these results by just bumping up the cpu multiplier..... able to acheive @3.9Ghz with 1.45Volts was stable in AMD overdrive stability test will test on OCCT when i ave time.... but i m unable to reach 4.0Ghz dunno y tried 1.555Volts but i would get a BSOD tried doing by increasing the HT but when it comes to 4.0Ghz it crahes no matter what..... can anyone enlighten me....:oops:

will be trying to OC at much higher speeds n post them once when they r stable.... one note though i m not planning for 24X7 OC but i m doing this for just the fun of it n to see upto where my processor is stable n can run 24X7 when need arises right now i m quite happy with stock speeds n the temps i m getting... thx guys this thread is gr8 n helpful.....

Will go up higher, but later, when I push pull my TRUE. Currently operating my TRUE with Delta 120CFM fan, will push pull soon after I acquire some zip ties. :D

You should not have quoted my image topgear. That is a waste of bandwidth. :)) And I have a 17" CRT box monitor, and I have kept the resolution of the image somewhere around 800 pixels wide. It is not stretching the image at all. :)

Thumbs need an added click, so I never post them, although mobile users will want to attack me for saying this. :ashamed:

re: Overclock List & Discussion Thread

yup - but on the previous page the image was the only thing that I can mention. and for the image resolution I've to scroll horizotally to see it correctly @ 1366 screen width and I'm using opera :p

This is strange, as I am on FF and my screen resolution is 1152x864. :cool:

Anyway, next time around, I'll try and lessen the resolution. Btw, now I am at 3616MHz, but I can't get it stable even after pushing vcore to 1.392V. I think I'll google up some AM2+ overclocking guides. :s

^^ You need to pump up more voltage ( around 1.5V ) and you can reach around 3.8 GHz with 1.52 vcore :p

^^ Amd recommends only 1.45 max limit for Phenom 2 940 1.50 if its water cooled Or L2n

re: Overclock List & Discussion Thread

Did AMD also specified some speed limit with 1.45V vcore ??

If you have proper cooling you can safely pump u 1.5V - If you want to achive a certain speed then OC does not always stays within manufacturers specified limit.

Take a look at these :

*ixbtlabs.com/articles3/cpu/phenom-2-overclocking-p1.html
*www.techspot.com/review/142-phenom2-overclocking/page2.html

So phenom II X4 940BE requires that much voltage ie around 1.5v to reach 3.6 GHz and beyond and for cooling I think it's safe upto 3.6 GHz with good air cooler:p

Here what tom's hardware guys are saying :

Overclocking with a Black Edition Phenom II is as easy as it was using previous Phenom chips—an unlocked multiplier remains the most straightforward way to scale up and down 100 MHz at a time on a 200 MHz reference clock. With 19.5x keyed in, we set the processor’s voltage to 1.55 V, which was the maximum AMD recommended for air cooling.

*www.tomshardware.com/reviews/overclock-phenom-ii,2119-3.html

here oc club setting :p

Processor: AMD Phenom II X4 940 @ 3.755GHz (200x18.5) 1.55v
