It seems i am getting owned by the overclocking bug. After overclocking my e4300 to 3.3Ghz, i went ahead with the overclocking of my graphics card, man i was in for a surprise. With the coolbit regedit, i went in nvidias control panel and to the 'Adjust GPU Settings' option. At default 8600GT works at 540Mhz Core and 700Mhz for Memory. Chose the option 'Custom Clock Frequencies' and started raising the core bus, 10Mhz at a time, once i got stable core bus went ahead with the memory bus again 10Mhz at a time. Guess what was the maximum core/memory combination i got?

715Mhz for core bus and 865Mhz for memory bus. Man thats a jump of almost 30% on the core and almost 22% for the memory. Amazing!!!!!!

Will be running the 3dmark06 test tomorrow for the scores. Anyone else using the 8600GT please post your overclocks and 3dmark06 scores here :hap2:

Well you cant really jump up the nos. and say thats that...you will have to bench it to see if its stable at those frequencies...
 
so hw much u finally gt the card for?As of the memory chips, is it the version having the Quimonda Chips or the one with Hynix? QUimonda will easily get to arnd 850Mhz~880Mhz

Its a graphic card not cpu that it wont be stable, one of the reasons that i am confident is because i played company of heroes for around 3 hours without any problem and the max i reached with the card was 750 core and 890 Memory but dropped back by 35 Mhz for both so i dont think stability would be an issue. 3dMark06 would just give you back numbers but there is nothing like playing games to prove stability.
The reason i havent given 3dMark score is because i wud download that hefty 500MB from office and bring it back to home today and then test. :hap2:
 
^^ Thats the big issue, immediate effects wont be noticed, but the card will burn out all of a sudden.

So unless you wanna fry ur card for some benchies dont run GPU's at speeds a lot over their defaults...

hmmm...though all the reviews for 8600GT say that it can be overclocked huge, and the temps. i am running on is around 85-90C on load, my psu is good, do you still think the card can be fried? :huh:

Thats the prob with GPU's unlike a CPU which becomes unstable, which is an indicator, there is no indicator for a GPU ie once it becomes unstable ie you start getting artifacts even if you underclock it wont solve the issue.

Dunno besides do not look at 3dmark scores as an indicator, do see if you see a tangible effect in games you play ie ( you can increase the detail level, or resolution level etc.)
 
well the card is under warranty so i think i should not worry much...and the shopkeeper has promised that i wont have to run here and there, he will change/repair it himself if something goes wrong.

Thats not a small OC on a Graphic card...

Would suggest you to OC only n games where it helps you...else keep default...

90C is not good mate...
 
Best is you can try out with ATI tool..use the find max mem/core. Look out for any artifacts at every step. after u find the clock at which it starts to artifact, downclock by 10%. Thats what I usually do. Also the XFX runs extremely hot @ load reaching above 85 C, so a fan directing some air is also helpful
 
Actually thebanik, they are exactly like CPU's, only thing is while a CPU over OC would make it not boot, freeze up etc etc, here you get artifacts if less power is provided/temps are too high.

So bench the GPU, and bench it hard, using rthbdril or something, check that the temps are within range and check for artifacts...

If OC'in a GPU was as easy as just increasing the frequencies and being done with it...na...thatd kill all the fun...

as i said before nothing beats the stability test of playing games, and i have played company of heroes for 3 hours and farcry for around 30 minutes and everything is fine, the temp did go up till 89C but i dont think thats alarming for these graphic cards, though i will change the orientation of my 120mm fan to throw air at it rather than sucking air out. With the power that a 8600GT takes there would be no problems for the coolermaster psu, temps are sort of in control and there are no artifacts, though would put the 3dMark score here by evening. As asked before do you know any store in delhi that is selling 8600GT's for around 7200-7500? SMC, CE are selling it for 8400, and another store i know is asking Rs. 8000, so getting nothing less than Rs.8000 here in delhi.
 
^^thatd kill all the fun

Buying a cheap PSU kills the fun & now Ocing w/o proper testing :rofl:
 
Lol...well that was a different killing the FUN..

This is different kind re..this is the fun we people have just to see our babies OC so well, to tweak them into perfection etc etc

The exact reason why some people prefer PC's over consoles...to get that HIGH...to get that control...

The high one gets of testing the PC can be awesome (yeah I am a geek, so what...:D)

Cheap(Cheap as in crap) PSU kills all the fun because well, if the rig doesnt work properly because of a poor PSU not being able to turn on the PC, hence forfitting you of all the pleasures of having the PC in the first place...

So, there is a difference in those "fun" :D
 
There's not much diff in CPU's and GPU's

both can get unstable at high OC's though the line between stability and untability in graphics rendering is not very clear, and that's the cause of all problems.

Graphics cards can be run well overclocked for years just like CPU's if it's stable and in limits, and here's the problem, Prime95 tells us that there's a rounding error, but even after 25 hours of game testing, the GPU might not have been all that stable, a slight variation in color calculation is not noticeable.

The wisest thing to do IMO while OC'in a GFX card is, OC it to the max, use multiple tools/games to check stability, and then back off the GPU a little, and the memory a little "more". And things should be fine for years.

This is just my opinion.
