Have you tried forcing the clocks, denesch?
Set an overclock profile with the default clock speeds.
Ok i think that mybe my CPU is slowing down card.
I will buy Q9400 is this cpu ok?
forget it mate.......... ive come to the conclusion in order to make these cards fly ''i7'' @ 4ghz is required, these cards NEED the ''QPI'' connection & the massive bandwidth they deliver..
also the DDR3 helps no end, this is where were starting to see what these new developments were actually for.
even OCed @ 950/1220 the performance increase is minimal on my Q9450 @ 3.6ghz anyway...
the most i can pull on vantage is 19.8k, that's pretty poor, ive seen single 5870s pulling more ...WITH ''I7''
but hey, its your cash.....:bang:
My scores: (furmark)
at 1024*768 is 22041
at 1280*1024 is 14355 This is my monitor resolution why is so low?
at 1440*900 is 17444 This is higher resolution and it has more score xD
Ok so tell me if this components are good becouse i will buy new one:
Intel Core i7 920 2,66 GHz
Patriot DDR3 3x2GB 1333MHz
Only if you oc that i7 at 4ghz.
I think that you dont need OC it becouse it has 4,8Gb/s transver
core2duo has only 1,0Gb/s
This is my 3Dmark score:
holy bottleneck batman.....:3eyes:
well, as i said you can CLEARLY see how your CPU is choking your cards performance...
I see many people getting HD5970 with crappy cpu.I really don't get their logic.
And 5970 is strictly for 2560x1600.
PS: Please check this before considering of buying HD58xx http://www.guru3d.com/article/radeon-hd-5870-review-test/23
well.... i never payed for mine, it was bought for me (im staff over at a windows 7 support forum, my Christmas bonus was a 5970 )
but your right, the sheer bandwidth these cards need is astronomical, my primary res is 2048x1152 so its not really overkill for me, but my 775 setup just cripples it.
the CPU is @ 80% on all 4 cores while gaming, but the 5970 cores sit @ about 50% usage..??
its bottlenecking beyond belief..
Actually your not bottlenecking your HD5970 at all.If your cpu never goes to 100% there is no bottleneck.Enable AA and AF to the max ine every game and you will be just fine.I saw in another forum HD5970 ON P4 and i was like WTF???? :3eyes:
but what about the fact that its sitting on a PCIE 1.1 slot..??, there's gotta be a bandwidth issue there..???
There aren't significant differences in pci 1.1 with pci 2.0
yeah ive seen the benches in this regard, but none of them were done with the 5970, it completely saturates the PCIE 1.1 connection & then some....
there's certainly a problem b/c i cant break 20k in vantage ..??, its gotta be a bottleneck surly..??
Well if you're running 3dmark at 1280x1024 there is a bottleneck then
lol...... but ive seen 5870's running the standard settings on vantage & pulling well over 20k, it cant be related to that..
i'll do a vantage run @ 1920x1200 & see if it changes but i dont think it will..
I dont understand you guys lol you all time saying that you need to overclock cpu too 4ghz
but i dont think so becouse normal i7 920 MUST RUN HD5970 NORMALY for sure and is no need to overclock it to 4ghz.
and why you dont need overclock:
Becouse i7 920 CPU has 4,6GT/s transfer rate.
Anny older CPU's has MAX 1,3GT/s
and older MB's use FSB that is slow,
but new one use QPI that is much faster.
so its clear now whats problem.
^^..... this is why i think im bottlenecking with the C2Q.
but the i7 still needs OCing to reach high numbers, an i7 @ 2.66ghz delivers a pretty mediocre score.
