First time Overclocking

deadmeatdan · 10 Aug 2011 at 10:21

Hi there My machine is running a core2duo 3.0ghz, with 4gb of ddr2 and i recently bought the 1gb GTX 460 card from gainward.

I also bought a coolermaster rs750 GX-series psu

i've installed msi afterburner and kombustor.

What are the next steps? anything i should take into consideration before i go tweaking those bars?

what are you overclocking firstly?

deadmeatdan · 10 Aug 2011 at 10:58

sorry i'm overclocking my GPU.

Default setting are:

Core voltage: 987
Core clock: 700
Shader clock: 1400
Memory clock: 1800

Im at work but Im sure my core voltage was 1012. then my clock speeds in my Sig. Temps stay around 35c.

deadmeatdan · 10 Aug 2011 at 11:28

your card is the 768mb version, surely there's a difference in the optimum overclocking speeds?

lee20010 · 10 Aug 2011 at 11:37

I wouldn't imagine the amount of Vram on the same card to play much part. Maybe on the voltage. I was only saying what can be hit. I could clock higher if I wanted

i've never overclocked anything before, is there a method i can follow?

ie: tweak this first, test with kombustor, then tweak this.

What temperatures are safe and what arent?

it idles at 40c with the fan on auto.

something strange is going on.. not sure what..

I upgraded from a 8800gts this morning, but now when i try to play bad company 2 (which ran perfectly fine before) it lags when loading the menu screen and i get severely low fps in game too...

strange...

i ran a whole number of benchmarks too and they all came out with a really low score, and average frame rates of 1-20fps which is terrible.

any ideas what could be wrong?

lee20010 · 10 Aug 2011 at 12:04

Have you updated drivers? i remember swapping from an ATI to nvidia and play games and it was very messy.

With Kombuster its simple to OC the GPU and quite safe. Temps vary really. My old 4850 wad around 75c

deadmeatdan · 10 Aug 2011 at 12:17

thats the first thing i did.

i'll keep looking for solutions for now

lee20010 · 10 Aug 2011 at 12:22

Sorry Im not being able to help much. Im stuck at work.

what is a safe GPU temp?

the best score i've got out of my card so far was running it at:

Core voltage: 1000
Core clock: 850
Shader clock: 1700
Memory clock: 2000

but the card reached 70c on the DX11 kombustor at 1680x1050 with 4xMSAA

is that safe?

or should I aim at a lower temp?

I think the rated max temp for that card is 90 something degs. Your Ram doesn't have a cooler on this card, so only attempt small OC on that, the core can get to around 900, but first things first, have you got it running smoothly? I had to spend about an hour removing all the drivers and bits n bobs that Nvidia install before updating my drivers for my 560 Ti. 70C seems quite high, but it is still (according to Nvidia) ''safe'' for your card. Download Heaven and 3D mark for better testing, the Kombustor is good, but Heaven, I find, shows the artifacts better.

I just found some1 who has overclocked it pretty high to 910 on the core with a 1.12vcore and 2100 on the mem. But to be honest I'd say thats pretty high unless you got some hefty cooling.

lee20010 · 10 Aug 2011 at 19:16

Well I have no idea why your running so hot. Heres a screenshot of my OC (sorry it took a while, I had to reply via my mobile at work)
