bought msi hd6850
really good card..cool
using with 10.10e

good luck and happy gaming

guys need to know what Vreg temperature of hd6850.?
mine showing 29 c ...is it really low or there is bug on gpuz 0.4.9

using msi hd6850here

mine not on aircon room ..but it used non reference msi cooler
gpu temp 1 2 3 are all slightly high compared to Kaellis
which around 50c fan speed at 50 % <--normal fan speed for this msi

@Revamperz
possible formatting the pc ?
incase some leftover causing bsod

maybe it need different kind of psu 12v rail
what your psu 12v rail ?
also notice that ur acbel r8 is 600 watt
http://www.acbel.com/eng/Product.aspx?id=40&&sd=31&&pid=173
and 6850 needs about 10-11A on 12 rail.u also need to count your cpu watt.. it will be another 8-10A so you need at least 25A

18 A for 12v1 -v4 ampere is kinda low ..minimum 25a to be safe
if u got spare psu with single rail ..better try it

oo yours is this one
http://www.acbel.com/eng/Product.aspx?id=40&&sd=31&&pid=175

ignore my previous post about your psu model

also check this thread discussing the hd6850 rails requirement
http://hardforum.com/showthread.php?t=1560740

my silverstone st560 can provide enough juice for 6850+3 hdd+dvd rom+ i7 920 +sound card +7 fans
iirc it all about good rails when it gfx

also..my friend told me that if it got lot of 12v rails..that extra rails power will be given exclusively to the another pcie connector
so that mean u already lost 18 A on another rails
i'm not sure if it true or not maybe some guru here can provide some insight to this

also i can confirm that ss 400watt with dual 12v rails..18a each can run hd6850 + e5200+ 2 hdd + dvd rom
(my neighbours run this setup)

can give your full spec..
or did i miss it in this thread

i believe that your psu is ok for what u have
but it depends on the power available on the 12v rails and which ones power the CPU and gfx.
did u try second pcie connector ?
or if u have ..molex to pcie connector to try it

8800GT have a TDP of around 105w (on the nets)
hd 6850 got around 121 watts based on guru3d power consumption
so it is higher than previous

105/12=8.75A
121/12=10.08A

2 Amps more than before

yea but sli power will pull from second pcie connector which probably from another rails...i guess no problem
but single high amps gfx probably going to have problem.
either u tried hd6870 just to check your mobo not bias to nvidia and it got no compatibilty problem with hd6800 series
forgot to mention that my concern is still on the psu problem

oo..yea maybe different rails on different cable
that molex thing dont work....i'm start running out of idea..
possible irq management problem ?

your problem almost like this guy except that you already change gfx

irq

about bsod
http://www.pcstats.com/articleview.cfm?articleid=1647&page=1

yea Silverstone Strider 560W sure can cf but hd 4850 cf not worth it since 512 mb ram unless u got 1gb version
and hd6850 rock

@Revamperz
safe mode running on basic driver just needed to bootup
so it possible that ati+ intel mb driver causing conflict when running in normal mode

oo..didnt know about that slowness..
even with high res ?

actually i did try 1gb version of my friend gfx
it more faster than my previous hd4850
it feel more smooth on high res ..
maybe because the game got some game mod that require more vram

no harm done reading the faq then

yea that why i change gpu
the faster the better

probably not psu
but do give a other psu a test just to eliminate one variable
if with other psu work .. that mean your psu problem
but still dont work mean vga driver + intel mb/whateve conflict

guys found some new beta here

st56f ..dont know about rating but it sure stable with my hd6850
been rocking since early c2d era until my i7
