Gigabyte EP45-UD3 Series Owners Guide - Page 937

post #9361 of 21187
AFAIK it should provide increased stability indeed when aiming for high overclocks but if you don't have issues getting your rig stable you're probably better off running your ram as fast as possible.

It used to be a "big deal" that whole 1:1 thing...

Some interesting stuff about it here. (not sure if I'm allowed to link to tomshw forum though)

Good news guys



Highest temps I saw was 71C at 100% load under LinX, which seems good to me?
vcore is 1.35, but CPUz showed at most 1.312v.

400x9 = 3.6

Memory is running 1066 with 6-6-6-24, at 2.2v 1.3 MCH (1.3 seems to be the only volts I can get stable on when I overclock ).

Now let's just hope that it'll work out, and I won't get any memory related BSODs.

So far, so good. Keep your fingers crossed.

Hello,

I have this board and would like some kind intelligent soul to help me understand
what the diff is and is it significant(See subject). I could of course do a Google search but I joined this forum to ask and help if possible not to be told to use Google.

Thanks

I believe if you run one gfx card in the first pci express slot, it runs at a full x16, if you decided to crossfire two ati cards together, it drops the bandwidth on both of em to x8 bandwidth.
GoodEnough.

And, for arguements sake, the difference between 16x and 8x is absolutely negligible. I believe the performance drop off on average is somewhere around 1.5% (if my memory serves me correctly) between 16x bandwidth and 8x bandwidth on the PCI-E.

With that being said, go for it. If they are both 8x, it'll still be faster than a single card at 16x

Cool. What is the hit from 16x to 8x? Is it 50%?

Thanks Man!!

im running a 5870 and 8800gt and i see no slowdown at all. Their was a review befor showing 2 5870s only lose about 2% when in crossfire pcie 2.0 8x has a ton of bandwith its got plenty for 2 5870s or even 2 5970s.
