I have a ASUS 5870 and Powercolor 5870, but crossfirex fails.

if start something put load on the VGA's, the system reboot and get this error:

HyperTransport Sync Flood Error

how to fix it

system is:

Phenom II X4 965 BE @ 3400
ASUS M4A79T dlx -
2x 2048 Gskill Trident 2000
Corsair TX850

Hi Destroyer, what score do u get with one card?

I did some more testing last night with the card and i'me seriously thinking that my Vantage score is low due to CPU bottleneck. I thought PII 940 @ 3.6 would be enough.

I've tried everything...that i could think if at least.

My GPU performance score is 12100 in vantage.

[Lightman]

I know i'm not in the best place for asking this but LIGHTMAN could you do me the favor and tell me what's your GPU Score in 3DMark Vantage performance with the 5870 stock clocks?

I would truly appreciate it.

Sure no problem!

I know some people are having low Vantage scores on their systems.
I was investigating this together with AussieFX but so far we don't know much.

Anyway here are my scores:

Phenom II @965 speeds (3400MHz) HD5870 default
http://service.futuremark.com/compare?3dmv=1454977

3DMark Score P13764 3DMarks
CPU Score 11128
Graphics Score 14944


A bit OCed Phenom II @3840MHz and HD5870 900/1300

So my score is below par then (PII 940 @ 3.6 with DDR2 800mhz. The 965 is an AM3 right? So u will be running DDR3? Do u think that would make a 2000 point difference in Vantage?

[Shark-357]

last night me and jcool were toying with 2 cards, crosfire gave us no problems but we didnt see much gain at all...waiting for new drivers i asume

Damn, we intend to bench with LN2 this saturday, but the way things are going now its gonna be a waste of LN2....

The weird thing is i sometimes get weird artefacts in Vantage when running CF.

Today i will try with bios 1504 for RIIE with bloomfield... if that doesnt work i dunno... the only thing i can do is to flash both cards with Asus BIOS if that will maybe resolve the problem

I get around P15000 as well with pII 955 3,7ghz, 2,4ghz NB and 1600 7-6-6-20 ram, 5870 @ 1000/1300...

with 950/1300 and unoptimized drivers (mipmap high quality, 8xAA edge detect, AAA and 16xAF on, though i think Vantage doesnt realize these settings) i get

3DMark Score P14149 3DMarks

Also AM3 which has better mem bandwidth.
Anyone here with a PII 940?

[Oese]

hehe OT but today i will get EK supreme cooler for the cpu and a mora radiator, will see how high i can bench the cpu then

You definately should be getting a better score. I'm running a PII 955@3800 on an AM2+ board(GA-MA790X-UD3P) with DDR2@1066 and I get the following score on an 5850 running 835/1080:

Total: P14445
GPU: 14979
CPU: 13049

I'm running Windows 7 x64 (rtm).
Which OS are u using?

My CPU score is 12x00 which seems about right.

Same OS as you are with the 8.66RC6 drivers from the AMD website.

Man, now i'm stumped. I think i'll uninstall Vantage and reinstall it.
Maybe a setting in my bios with PCI-E needs to be changed.

[mR Yellow]

Do u guys think it's worth it to upgrade to this mem? I'm currently running vanilla DDR2 800 which is impossible to OC.

[Jamesrt2004]

imo not worth it, save up and get a good ddr3 board + ddr3 ram seeming it'll last longer buddy, don't think it would make that big of a difference to warrant the cost


have you tried just reinstalling your os, sometimes i do that time to time cos my perfrmance can sometimes just DIE for no reason,

I might just take that route, but i not to keen to do it.

Thanks Mate. I'm still waiting for my 5870, but now i know that if i get a low score in vantage is due to my AMD Phenom 940 System.

[Oese]

<- win7 x64 rtm as well...

[mR Yellow]

Maybe the mem controller on the AM3 is much better than the 940.
Another guy on TPU is having the same issue with similar specs.

[Oese]

[mR Yellow]

Nice score but i the 955 is an AM3 CPU with the new controller.
I need someone with the AM2+ 940 to compare.

[NanoBullet]

as soon as i get it i will post results so you can compare them!

[Stoner@Large]

You have to flash to the Asus bios first to remove the overclock caps.

kinsa tuff when there isnt a Higher limit bios for the 5850 yet, MSI said there gonna realse one. they released one for the 5870 the other day that gives it ax core of 1800 and 2600 on mem

Just look at my sig. or read System Info in my links

Now I know that common theme for low score guys is Windows 7 x64...

Well i tried:

-1504 bios for RIIE + i7 920
-Install Vista Ultimate 32-bit and Windows 7
-flash cards with asus bios
-changed CF bridge
-changed psu
-tried all availble drivers
-tried a few ram modules (corsair, cruical, take MS)


And its still the same crap... artefacts and decreased performance when running Crossfire...

ing unbelivable, after spending 700€ on this POS....

[Jamesrt2004]

is it overheating or is it just du to the fact there isnt actually a good driver yet?...

wait for 9.10
