ATI Radeon HD4870x2 - Crap performance on Vista Ult 64

Or am I missing something?

Very interesting link.
The combined 12V output is then 260W, which in theory would leave 210W left on the OP PSU (according to the newegg link).

But I disagree with the 8/6-pin output power. On newer HX(5/6)20 they included the 8-pin connectors as standard, while mine only have the two original 6-pins. But the output power hasn't changed. The 75W/150W statement on the 6/8 pins are minimum/recommended/whatever requirements (from what I've read, IDK). At least on my PSU the PCI-e connectors exceeds both requirements.

But yes, in essence a PSU with 8-pin connectors should be used when the grafic card requires it. If one would want a 6 -> 8 converter it would require a little homework of how powerful the supply really is.

 

[InnocentCriminal]

He has the 2 6 pin in it wich is starving that x2 .

He doesn't once state that in any of his posts, so I don't know where you got that from. Unless that PSU only has 2 6pin cables and not two 6 to 8pin connectors.

Heya guys, another reseller tell me about a PSU called S-TEK that got 800W. Anyone knows that PSU?

4870x2 and a 500W PSU (dont know the rest of your power draw as you have not filled in your specs) = An accident about to happen whatever your operating system, and yes, I read an article about a year ago about the different methods of system and hardware management between XP and Vista, that showed about a 25W draw difference between the two OS's with identical hardware at identical speeds, that 25W maximum margin you are playing with there will not only cost you the price of a PSU but perhaps a motherboard and other stuff.

Edit: try downloading something like motherboard monitor or even just check your hardware monitor in BIOS, I reckon your rails are being dragged down to well under their ratings.

As a matter of interest, what make/model is your PSU with what amperage?

Well i dual boot and watts difference from XP x64 and Vista Ult x64 is about 3 watts.

All though he might be running DX10 under vista which i would think is making the card work harder ending with a possible PSU issue.

Maybe if he tried DX9 and not DX10 and see if there's much difference, all though you should never run a PSU that close too it's max.

Get a better PSU just to be safe even if it was not it anyways, it's just not worth the risk of what could happen....

From my 3870X2 I can tell you, CF runs better on Vista, I never installed XP with the 4800X2.

4870X2 is bottlenecked by PCI-E 1.0 Motherboards, you get better scores with PCI-E 2.0.
Your CPU is also bottlenecking

Crysis runs faster in Vista 64 but using 32bit executable, if you run DX9 you can use r_texturestreaming = 0 it will give about 10fps more.

(3870X2)
Run #1- DX9 1280x1024 AA=No AA, 32 bit test, Quality: High ~~ Overall Average FPS: 46,97
Run #2- DX9 1280x1024 AA=4x, 32 bit test, Quality: High ~~ Overall Average FPS: 37,12
Run #3- DX9 1280x1024 AA=8x, 32 bit test, Quality: High ~~ Overall Average FPS: 36,33

TEXTURE STREAMING = 0
Run #1- DX9 1280x1024 AA=No AA, 32 bit test, Quality: High ~~ Overall Average FPS: 56,11
Run #2- DX9 1280x1024 AA=4x, 32 bit test, Quality: High ~~ Overall Average FPS: 42,41
Run #3- DX9 1280x1024 AA=8x, 32 bit test, Quality: High ~~ Overall Average FPS: 43,00

Configuring Crysis using Budget monitoring also increase your performance.

sys_budget_numdrawcalls = 6000
sys_budget_videomem = 512
sys_budget_sysmem = 6142
sys_budget_frametime = 80
r_TexturesStreaming = 0

Using Only texturestreaming
Run #1- DX9 1680x1050 AA=No AA, 32 bit test, Quality: High ~~ Overall Average FPS: 4635

Using Texturestreaming and Budget config
Run #1- DX9 1680x1050 AA=No AA, 32 bit test, Quality: High ~~ Overall Average FPS: 4869

Before you ask why I´m showing 3870X2 results, its because, my 4870X2 isnt far from this results since my MB is PCI-E 1.0, the big difference now is that I can play with AA with no performance drop ultil I get a new MB

I still don't think that you are PSU limited, but whatever.

Have you tried any other games besides Crysis? UT3, the latest stalker and even Vantage all make heavy use of GPU.

 

[Mannaro]

4870X2 is bottlenecked by PCI-E 1.0 Motherboards, you get better scores with PCI-E 2.0.

Hmmm, i think my M2N-Sli Deluxe have a PCI-E 2.0.......

Dont have tried UT3 but other game yes, all crap performance on Vista64.

Ah, i made a typo on the PSU above, is not S-TEK but S-TECH.

How did you obtain these numbers? Power outlet? Consider a 500W PSU with 80% efficiency is capable of 625W outlet draw...

 

[SK-1]

i thought I saw a 750 for sale in our own FS thread.

Yes this is measured at power outlet, my PSU ia a PCP&C Silencer 610W.(87% efficiency at 60% load)

 

[TooFast]

500w power supply! you need min 750

Crysis, 3dmark Vantage (Jane Nash), 3dmark 2006 are the games I have problems.

Crysis is just a litle faster then my old X2, Vantage only Jane test got lower results then normal, and 3D 2K6 I get only 16K, very close to 3870X2.

Grid, DMC4, COJ, Mass Effect, COD4 100% Ok, all of then I got what I should get compared to the results from a friend with a E8500@ 4.2 with PCI-E 2.0 Motherboards.

He can run Crysis island bench @ 1680x1050 VH with a average of 44Fps, I get 29fps clean with no Cvars, and 32fps using Budget Cvar, this under Vista DX10, Clean Install with CAT 8.8 official.

Lostcircuit make a review using a PCI-E 1.0 MB and got similar results.

500w power supply! you need min 750

Considering the poster above you runs his on a 610W, I'd say it also depends on the quality of the PSU...

Found a Corsair TX750W ... seems nice... found here (italian page sorry): http://www.computerdiscount.it/ProductDescription.aspx?PrdId=C0.54 &PrdP=144,00

That is a nice psu. Go for it!

I don't think so:
2 x PCI Express x16 slot at x16, x8 speed

http://www.asus.com/products.aspx?modelmenu=2&model=1160&l1=3&l2=101&l3=301&l4=0

Not stating explicitly PCI 2.0 indicates, to me at least, that it's 1.1 . How much it will affect your performance (if any at all) is beyond me though.

if you do go for the corsair, please report back and tell us about your progress! I'm always interested in PSU requirements and running systems.

As I mentioned, he may not be limited, but I cant see how he can be drawing more than 225W which isnt sufficient to run a 4870x2 at load.

The lanes available to the slots dont have any impact on whetehr it will be 2.0 or 1.1 whatsoever if thats what you are suggesting (not sure if that is what your suggesting?)

However you are right, the board is PCI-E 1.1, it ws manufactured in 2006 and PCI-E 2.0 boards were not available until 2007.

 

[Animalpak]

I hope only that your X2 doesn't is not lack because you have risked so much.

You can find a lot of PSU with 800W for a cheap price and good quality.

I don't succeed in understanding because you have not changed the PSU, strange that the Suspect has not Risen You Seeing A Beast As The 4870 x2. That VGA is very hungry of power

I got a nice Corsair 750W PSU. Nothing. So must be a driver issue. I'll install a temporary XP32 session on my hardisk till they release a better driver for Vista64.

Its a clean Windows Installation ? I have a lot o problems befere reinstaling everething, a lot of driver issues.

Did you installed any of those DirectX Redist from March or August 2008 ? After I installed this Crysis in DX10 became unplayable and you can remove this DX update, reinstalling Crysis doesn´t fix this also.

Any chance you PCI-E is overclocked ? ou option like PEG Link Mode aren´t at its defaults settings ?

You should be playing Crysis in Vista faster then in XP at the same settings.

 

[Mannaro]

Tried even on a clean installation of Vista Ult 64 Sp1. Havent tested on Vista32 but i suppose it works. The issue is on 64bit.
And, all my hardware is factory setting. No overclock and up to date.

Wow. I'm sorry to say this; but:

I told you so

They have it on the egg:
http://www.newegg.com/Product/ShowI...ion=FSP Group Blue Storm II 500W Power Supply

And yes, FSP are known for good PSU's. Before jumping on the power supply train, I would suggest you either try to borrow a PSU from a friend which is beefier, and/or buy a wattage meter to see what your computer is drawing.

The combined 12V output is then 260W, which in theory would leave 210W left on the OP PSU (according to the newegg link).

I still don't think that you are PSU limited

My work here is done.

When your done patting yourself on the back...realize that even If It wasn't a PSU Issue...now...It would have become one eventually seeing as how he was running It off of a PSU that was/Is WELL below the recommended wattage...so eventually (maybe sooner...maybe later) he would have had Issues...possibly even damaging his card or other equipment.....so the new PSU recommendations In this thread were warranted.

And to the OP...you really need to list ALL of your parts In your rig so that this Issue can be looked at further...I'm actually surprised no ones mentioned that yet....without a listing of your parts.....theres not much more that can be done.

Quick search of google finds nothing like your Issue....so I think It's something In your rig not playing nice with Vista64...maybe the Vid card Itself....which would warrant an RMA.

Once again...list your parts.
