GTX 460 SLI, Slow Performance & Weird Interference

I'm blaming it on the motherboard personally... asus boards don't rate highly in my books.

All the reviews I read gave them great write-ups; the P6T in particular when it came out. I'm interested to know what problems you have had with Asus; I only build new systems once every 4 years or so; so I'm not always savy in whats going on.
 
Yeah they are very popular for some reason... lot of people seem to run them sucessfully...

Personally I think the component quality - especially capacitors - has slipped over the last few years... not a patch on what they used to be like 7+ years ago. Lots of random little issues.

I didn't do this to a £200 board lightly... http://aten-hosted.com/images/DSC00524S.jpg :P
 
and the advice on the PCI-E bus change? whats the theory behind that? :) and whats your opinion on the the noises I mentioned? think its possibly the PSU as the problem?

Its a bit complicated and a whole topic of its own - there is no one reason to use 101MHz (or another frequency) and the reason for using that can differ from board to board. Its a bit of a "cure all" tho that can sometimes fix things for no known reason when nothing else can.

Generally it comes from boards where 100Mhz + overclocking results in unpredictable PCI-e bus speeds whereas setting it to 101 locks it there.
 
Another thing to check - if your using Vsync is the Hz in the control panel actually 60Hz - I remember some people had issues because windows would set 59Hz while the monitor was using 60Hz - causing flickering issues and slowdown.

blizzard have said that sc2 does not support multi gpu's (not offically anyways)

Yeah I just read that after googling the strange slowdowns in SC2's in-engine cutscenes'; apparantly it might be a bug with lighting and SLI.

I've checked comparitive benchmarks for the FFXIV benchmark and I'm actually getting in line performance with everyone else. (2500-2700 as a single card; 3500-3700 as dual). My old 4870 on its own got 2300ish.

I'm going to give Crysis a go now that I don't have the strange blue flicker anymore. it disappeared after I overclocked my i7 to 3.8Ghz. Anyone got any ideas why?

Yeah I've always had the 59hz issue. even on my ATI. tried to force it to 60 but bounces straight back to 59hz. However problem of the flickering blue is gone now that I'm running my CPU at 3.8ghz
