X850XT PE problems

[Silvestre]

set your pci-e related setting in the bios to 256 instead 4096?? (don't remember the right number). do that, and see your score gets better.

I too have problems overclocking my NON PE, I get to about 530-540 core and thats about it, WTF is that, even witha PIC Blower cooling the back of the card and rear ramsinks.

hmm it`s getting better 13450 3dmark03 points

i think the cat 5.3 and the the new patch for 3dmark03 isn`t good for my scores...

is there any chance to change the pci-e speed on my dfi lanparty nF4 ultra-d

cause of my innovatek nb cooler i had to stick the card into pci-e slot2

everest told me that the second pci-e slot is running with 8x

which is the fastest driver for an x850xt ??

[khellandros66]

Just ordered the ATi Silencer 5 from Frozen CPU, I will see how this goes..

I gave my PE some more volts and got these scores

Maximus... I don't know if it's wise running your X850XT PE in the second PCI-E socket. You need to put it on the first to get the best performance since it will be on a 16x lane. I feel for you though.. I really wish I can find a NB chipset watercooler (that I can get in the U.S.) that will fit in the DFI board.

I might try getting an Abit board instead.

[Silvestre]

yeah, there is none that is quite thin yet good for the NB. or at least, somebody should design it to have a side outlets instead of top outlets...the biggest problem is the outlets of the hoses...

I got an X850XT PE that artifacts like crazy in Atitool (yellow dots). I even underclocked it to 470 on the core and it still does it. However, all benchmarks work well and I can play NBA Live 2005 just fine for hours. What gives?

i have exactly the same problem! and when i set it to find the max core or mem speed, guess what, it starts downclocking my card more and more down to 40mhz core where i get artifacts like crazy and my pc restarts

and when ocing with atitool i get random crashes and freezes for 30seconds with atitool crashing... i thougt this was THE tool for ati cards?

well it doesnt work AT all for me, lol

[SIK_L_CELL]

I use Rivatuner and find my own max clocks. Atitool is way too buggy.

[saaya]

same here, used rivatuner and 2k5

the first x850xtpe does 600/655, the second does 595/627, both artifact free and totally stock with fan speed set to max all the time and 18°C room temp

upping the core by 10mhz gives me almost 50 3dmarks while upping the mem 10mhz only gives me 20 3dmarks, i think the x850xtpe's really have much more relaxed timings on the mem and maybe chipset/vpu than the x800xtpe's wich is why they are slower clock for clock.

too bad i dont have an x800xtpe to compare both

[SIK_L_CELL]

I find that the non pe's clock much higher that the pe's. I use Sapphire X850xt's. Everyone I had except one hit 700.

[saaya]

with what cooling?

and from what ive heard the xt's oc to around 560 vpu average with stock cooling.
why would the highest default clocked card overclock worse than a card that comes clocked lower by default? doesnt make much sence...

[khellandros66]

Well I got my Silencer the other day, with ATiTool i can clock to 560/620 but 3DMark fails on me and I reboot. With RivaTuner I can make runs at 540/618 but no higher and I occassionally fail.

Core temp is about 50c btw

[bobmanfoo]

wow, i was hitting 590/625 with bone stock

[SIK_L_CELL]

with what cooling?

With ambient water.

I can only tell you my results. The numbers speak for themselves.

Here are a few more examples of a card I got today from Newegg.

X850xt non pe (702x639) I havent put on the ramsinks yet, so the scores are a little low.

Water I think, and maybe vmodded.

[SIK_L_CELL]

Yes, water and Vmodded.

[perkam]

Yes, water and Vmodded.

Very nice. Only 1k (i know i know, its 05) less than OPP's score on Phase. For $450, thats some kind of power.

[SIK_L_CELL]

Im getting even more out of this pig. The clocks are 714/645 for 05, and 711/654 in 03. Unfortunately my DFI SLI-DR lost its pci-e slot so I cannot bench till my replacement arrives.

Good stuff Welfare

How did you lose the PCI-E slot?

Ahh, my alter identity. The slot just went bye bye.

Heres @1.65V and no tweaks or pause in beetween test...
