Noob sli question

[coxroach1]

I am fairly knowledgeable on single gfx card and cpu overclocking but am about to enter the dark world of sli.

Is there any tips, adivce, warnings i should know before i do.

I have heard that inorder to overclock both gfx cards i actually only change the primary card clocks and they are replicated to the secondary card. Is this right?

Well, if you haven't bought your GT yet, then wait until mid July cause they will be under £80 by then.

I havent got it yet and was planning to get it on the 30th May (getting a bit of spending cash on that day). What makes you so sure about a price cut.

Bunch of new cards coming out, that will drive prices down

Old 9800GTX dropping to $199 which should mean £120-£130 over here. That means the GTS G92 will have to drop from £146 to below £120 and leave a gap for the difference in performance so at a guess about £100.

That then means the GT which sells for £111 will have to be below the GTS G92 again for the price/performance differential so I guess around £80.

Plus with the 4850 pretty much matching the 9800GTX for £130, Nvidia would have had to drop the price of the 8800GT from £111 to sell them anyway.

Sounds more than possable, good call!

Any ideas on my actuall issue tho of how to oc a gfx card in an sli setup

Usually you can just open rivatuner - select the cards and one will show the overclocking options and the other won't...

One thing to watch out for tho (and make sure you have a copy of everest to hand as it seems to be the only thing that highlights the issue) occasionally one card will overclock to your settings fine but the other card will only clock to slightly above its 2D clocks - in this case you will need to toggle the multi-GPU/monitor acceleration mode between single and multi performance modes til you find one where the clocks on both cards are running properly. So far I've only seen this with bridge-less SLI setups but it may happen with bridged too.

Plus the fact that the 4850 has less of an AA hit than the 9800GTX.
