Nope.....ATI's can handle way higher PCI-E frequency than NVIDIA's.....I have fed an 2900XT up to 170MHz PCI-E before it freezes....and benched it at 165MHz PCI-E.....;)
My eyes are glued for these new mods :)
George unfortunately if you look at my Location it says : Crete ... :( I know Athens is 30 min away (by plane of course :P), but what am I gonna do with school ? ... :) Uh never matter, next year ;) Give us the mods plz ... :woot:
I hope you guys have a Yorkfield to play with since QX6850 @ 5,4 GHz won't be much fun :)
How much does overclocking the PCI-E slots help with 3D06 scores? And if it does, how far do you guys usually push them? I usually OC them about 10MHz.
I have seen 160MHz on PCI-E and it eaily completed 06 run!! I think it helps a lot but its more to do wid stability.. i guess. May be other knowing more will help clear it.
I also want to know, will Hipro be using his own power supply? Hehe
Only 4500watts? :eek:
how did it scale in 3D???
have you compared results from 100 - 150 and what was the point difference
hicookie tested P5E3 from memory and there was absolutely NO points difference between 100 and 150MHz whereas on P35 based mobo there was 800 point different but i am not 100% sure what 3DMARK bench it was now and haven't got hicookie's thread handy here
Hi,
Dont know if Hi-cookie was aiming for better OC on cards or not.. just bunmping da PCIe clock wid same speed on Card(s) wont make your score go up. But I guess wid PCIe bumped one can see cards wid 920+ on 2900XTs in CF. Tho that surely makes SATA ports unusable.. one has to switch to old PCI RAID/IDE card.
As I mentioned above also.. I am no expert and may be Hipro or others who have tested X38 with CF can clear this. :)
ASUS P5E3 WS Pro (x38) and setfsb: When setfsb starts, shows 150MHz PCI-E whether in bios IS set at 120MHz PCI-E.....(A different PLL chip by a letter only on this mobo).
When I put it at 170MHz PCI-E, it will propably be ~ 140MHz actual (I will measure it when I'll put this mobo on again)....I didn't see any gain out of it to be honnest....
I have seen a small gain on the ASUS Blitz Exteme from 120PCI-E to 165PCI-E....2k5 ~ 150 marks more or so.....So I think that it's NOT like the good old days with the AGP..... :D
Another thing I have noticed is that the NVIDIAs on the Blitz, can handle up to 145MHz PCI-E, were the ATIs can handle 165MHz PCI-E.....
Overclockability of the CF?......Let's say that IF I leave the bios setting at 120MHz PCI-E, I can run the bench with the VGAs at their "edge" on air BUT when I put it via setfsb at 135 - 140 -145 - 150 - 155 - 160 - 165, some times VGAs are rebooting the system....No more MHz out of them by raising the PCI-E....
Thanks for dat long post, Hipro :)
Clears a lot of things about PCIe and X38.
