Vision Tek 4850 review

[jimmyz]

been hard pressed for time today, and internet has been going out along with the power. here is the first round in vista 64 ultimate.

Test rig:
QX9650 @4ghz for all of the non o.c runs.
4gb Patriot Viper 8500 ram. @ 960 5-5-5-12 all runs
DFI LP X38T2R running the chip @10 x400mhz for 4ghz
4 Seagate Hdds in Raid 0 dual booting XP PRO and Vista 64 ultimate.
Drivers show as 8.5 in ccc 3d driver is irect3D Version 6.14.10.0590


Some notes before the testing. The fan speed very low on the factory bios, I haven't been able to use any fan control to raise the speed so far. The temp is most likely fine even with an Idle of 79c but Being an XS'er I removed the factory thermal goop and replaced it with A.S. Ceramique. the idle temps are now 55c most of the time. That was a huge jump and I wonder if all of the cards suffer from this as I have seen rumors of other 4850's with similar temps (IE: FUD).
The card makes no capacitor squealing noise even during ATI TOOL scanning. I also ran 3d01 which makes most cards squeal if they are going to, not a peep out of it.
During testing I have noticedThis card seems very smooth. VPU recover works perfectly and the overclocking seems very rewarding. clock speed seems to play a huge role in performance of this card.

First up vantage.

As you can see it seems to scale well with the high resolution, I still can't get Crysis to run the proper bench, it keeps starting the game instead, any ideas?

Just press alt+enter when it's running and it should run in full-screen again... and any more times after that you run it. I had the same issue once with my 8800GT 512 and couldn't figure it out at the time either .

Hi jimmyz
i have ASUS 4850 card, and am experiencing the same thermal problems, now i am waiting for ac accelero s2 cooler, to help my new ati card get rid of some heat.
I have also tried some games with it, and so far i could boost everything on max with 4xaa 16af (1360x768), except crysis which i dont have (tomorrow i will try demo).

Does anyone know if you can use a MAZE4/5 on this card?

Same mounting holes as 38 series, so I believe so.
