I have a lot of weird problems with the X2.I had none with the 4850,even with the Crossfire setup. I first installed Cats 8.11, Vista 64 said that it is disabling one of the GPUs,during the driver installation. After some seconds, the screen went blank and I had to restart the system by guessing when the installation finished (when it asks you for a restart,you have to press Enter.).After the restart,the display was ok,in CCC both adapters appeared and but when I have started Vantage, in the Jane Nash test it was artifacting (like some spikes going up from the water). This spike problem was also present at 4850 Crossfire, but it was solved with a reinstallation of Vantage. Did a reinstall, but the same problem occured.
I have started after that Grid, and there were in the menu the same spike artifacts and then the screen went blank and CCC said the display driver was restarted.
I have uninstalled Cats 8.11,put 8.10. Now the GPUs were appearing in Device manager but with an exclamation mark, and Windows said the display driver could not be started. I have installed after that 8.10 hotfix. Same issue !
I have gone back to 8.11 and something very weird happened. Windows sees the 4870X2 like 2 4550 in Display properties, but ATI CCC sees the card correctly. Also,both GPUs are seen and also GPU-Z sees the both cards correctly.
I have ran this time 3DMark2006,no artifacts!Then ran Grid,which was artifacting,no artifacts! Then started 3DMark Vantage! Same spikes problem!
Could anyone tell me what could be the problem?Why the card does not work with the 8.10 Cats and why so many weird problems in 8.11?In 8.10, not even Aero interface was loaded.

Your power supply is too small: eXtreme Power Supply Calculator Lite v2.5

It says to me you are right at the edge...which is probably not enough...

also the artifact in Jane nash are 100% caused by system ram instability. I confirmed this through my own testing. It has to do with crossfire + ram issue

DFI LanParty LT X48 T2R +2st Sapphire HD 4850 problem

I everybody (hi dr nick).
I hope that there is someone out there who will be able to help me. I have a DFI Lanparty LT X48 T2R board and i was running a 8800 GTS 512MB video card but I got a good deal on two Saphire HD 4850 Dual Slot cards (the one that has a new cooler that looks like the intel stock cooler). So i figured I would try running some crossfire action.

Well. I unstalled all Nvidia drivers and installed the Catalyst 8.11 drivers (win XP SP2) and tested the first card. I got some nice results but the fan seems like its running amost full speed all the time. The temperatures are great (40-45 degrees idle) and even if i set fan speed to 20% in CCC, the fan spinns down some, but still sound WWWWAY more then my old 8800 GTS. Anyway i then insrted the secound card and the fan is the same on that card to. I also installed both crossfire bridges. Uninstalled the drivers and reinstalled them. I got a nice little message that told me to enable Crossfire, so i did. I checked GPU-Z and both cards ar listed and crossfire is enabled. However one of the cards run at PCI 4x only. The other run at 16x. Well i started 3dmark03 just to test the performance. The loading screen for the fiorst test was REALLY slow and the test got me about 20-40 fps in 3dmark03! I aborted the test and disabled crossfire and tested 3dmark03 again. Now i get abour 500fps. So it seems normal. I the tried to remove one of the crossfire bridges and this time i get 16x on both cards in GPU-Z but the bad performance still persist. I also unsinstalled the drivers and reinstalled them, no change. I testeted v 8.10, still no diffrence. I have tried the lastest intel chipset drivers. Still the same. Im clueless. I dont know whats wrong. Anyone got any idees?

Problem was not hardware related at all! I have reinstalled vista, put Cats 8.11 and it worked without problems in all tests.

@Tjalve

I got confused!

Did you fix the x4 problem?
Make sure that both your card run at x16 speeds.
Also, make sure you have enabled Crossfire from CCC.

And you only need one bridge. The one close to the back of the card were all the outputs are. (DVI etc)

Are you using the latest bios?

yes. When i removed one of the bridges (the front one. So i have just one in the two back slots now). Both cards are now running at 16x speed. Of course Crossfire is enabled. Thets when i get the REALLY crappy performance (20-40 fps i the first 3dmark 2003 test).

Im not sure what BIOS i use, but that should not be the problem. I have updated my bios at least once.

im sorry but i cant aggree with the "100%" part of your statement.
with my first gtx280 i had artifacts during vantage test . it was replaced. the replacement together with the same ram and ram settings, showed no artifacts during vantage test.
then on another gtx280,(gtx280no2) and my 3rd rig setup ,with different ram, i once again had artifacts during vantage. i upgraded to a different nvidia driver and the problem went away.

i dont doubt the ram part of your statement but i think there are other factors inplay other than just ram stability.
maybe theres more than one cause to this problem? maybe more than 50 causes lol who knows?
no offence mate , i know your alot smarter than me but the fact is i managed to overcome my vantage/artifact problem twice without adjusting ram .

just to clarify things... which ram slots work best? green or yellow?

green the one closest to cpu

why all bios after 714 lanparty lt x48 have bad memory performance copy and write???? after 5 or 6 new bios no fix :shakes:

for example
mem write 714 8000mb/s after 714 bios same setting...6600mb/s

Hey Zsam, what was your solution for that issue?

My x38 started to give me that CODE 88 when I first power the pc up (it's a 24/7 machine so I never had to deal with it). :shrug:

So I have to clear CMOS without battery to get it working again, and I every time I start the PC next day same cold bug CODE 88.

Solutions will be appreciate as this X38 should be rock solid and no OC on it.

Thanks.

I solved my crossfire issue. One of the card had a slight modified BIOS. I tried to use another fanmode in an attempt to make the card more quiet. Since it didnt wok i didnt flash the other card with that BIOS. When i used the original BIOS on both cards. It workes like a charm.

Strange that a simple thing like that can ruin everything :)
Btw. I didnt change the BIOS. I just modified the original with other fan settings.

That's weird because I am using my own modifications of the 4850s' bios (fan settings only, too) and I don't have any problems.

Anyway, glad you found out the problem :up:

best solution for me was to box the board:rofl:
its them damn bioses
newer bios should be better not worse
you need to try em all:rofl:n keep the one that likes your cpu n memory best
i'm usin my ut p35 n happy its kickin x38-48 ass
to me that 88 code is a dfi bonus:rofl: price you pay for a good board
i found that if you set on plain aggressive setting the gskill clock higher
n maybe you need to bumb nb lots of stress runnin 8 gigs @ high clocks

Hi All,
I have some problems with DFI LP DK P45-T2RS Plus and Nv9800GX2. I've tried all the BIOS-711, 725 beta, 812, 1003 without success. When I clock my system (CPU-4750, video 755/1944/1100), even I can not pass 3D Mark 06. This motherboard can be very good for Super Pi or to achieve higher FSB (I also rich 640 FSB), but I am not only overclocker, but gamer. I spent a lot of time for testing and changed with new RAM G.Skill 2x2GB 1066, because I read in some forums for incompatibility of RAM 1200, but I don't expect it would be incompatible with my video card. Owners of the 9800 GX2 suffer from poor driver support from Nvidia, and now from incompatibility of this motherboard. I think this is a problem of the BIOS of DFI, because I'm not only one. In DFI forum there is a lot of owners of 9800 GX2 with the same problem. I hope support team of DFI to do something about it with new BIOS. About the poor 3D performance with 9800 GX2, here are some results with my old Asus P5K Deluxe and E8500 C0@5084 MHz:
23109 Marks http://img149.imageshack.us/img149/7...3109je9.th.jpg
and now with DK P45-t2rs+ and E8600@5083 MHz:
17921 Marks :confused: http://img149.imageshack.us/img149/6...7921oa7.th.jpg
For me it's definitely motherboard problem and I hope it will be fixed with new BIOS.

So, my question is, have someone problems like this with DFI LanParty UT X48-T2R and 9800 GX2, because I want to replace my DK P45-T2RS Plus with UT X48-T2R.
Thanks in advance!

My X38 doesn't run G.Skills it's a Q6600 with OCZ Flex all on stock. But bumping vNB and Vdimm didn't help.

I was able to solve the cold boot CODE 88 problem this weekend. So far I turned the power off the office twice since Sunday and it's all good.

Solution was to re-flash bios 2 times with the same BIOS, followed by a long CMOS clear with the battery out.

Don't ask me how did I get to this methodology all I know it worked. :rofl:

Hi Everyone wonder if you can help. I have this board (UT version) its stable with prime and memtest for several hours but some games are crashing. Must be the overclock because if I run stock then nothing crashes.

Happens usually after a couple of hours with few of my games.

My Specs are:
Intel Q9550
DFI UT X48 T2R
Gainward 4870x2
4x1GB Corsair Dominator CM2x1024-8500C5D
XFI Xtreme Gamer Fatal1ty Pro
880W HiperPower HPU-4M880-PE
Thermalright Ultra 120 Extreme
Thermaltake Xaser V1

Here are my bios settings:

Code:

Clock VCO Divider Auto CPU Clock Ratio 8.5x CPU N/2 Ratio Enabled Target CPU Clock 3400MHz CPU Clock 400 MHz Boot Up Clock 100 MHz Dram speed 400/1066 PCIE clock 110 MHz PCIE Slot Config 4x NC CPU Spread Spectrum Disabled PCIE Spread Spectrum Disabled SATA Spred Spectrum Disabled Cpu Feature Multicore Enabled Rest Disabled Voltage Settings CPU VID Control 1.33750v CPU VID Specail Add Limit Enabled CPU VID Specail Add Auto Dram Voltage Control 2.150v SB Core/CPU Pll Voltage 1.640v NB Core Voltage 1.220v Vcore Droop Control Enabled Clockgen Voltage Control 3.60v GTL+ Buffers Strength Strong Host Skew Rate Weak GTL Ref Control Disable Dram Timing Enhance Data Transmitting Normal Enhance Addressing Normal T2 Dispatch Enabled TCL 5 TRCD 5 TRP 5 TRAS 15 All other Values Auto/Default Read Delay Phase Adjust Auto/Default Clock Setting Fine Delay Dram Clock Driving Strength Level 6 Dram Data Driving Strength Level 8 CH1 DLL Default Skew Model Model 0 CH2 DLL Default Skew Model Model 0 Fine Delay Step Degree 5PS All other Values Auto/Default

This is my first DFI board and if anyone could help I would really appreciate it, if theres any settings that look wrong or if theres any helpful advice it would be most appreciated.

Many thanks :)

Try dropping you PCI-E clock back down to 100mhz
01-04-2009, 08:58 AM
JohnEJohn

Tried that a while back but still no good, also ran card at stock but still get the odd freeze/reset.

Can you think of anything else or see any probs with my settings?

Thanks

SNiiPE_DoGG

DO NOT run PCIE frq @ 110mhz you will kill your hard drives, cause errors and all around suck. no greater than 105 for 24/7 PCI-E
01-04-2009, 10:09 AM
JohnEJohn

Thanks for the headsup will change to 105MHz

Anyone got an recommendations on anything they think I could change to increase stability?

Cheers

u need to set a special add %
01-04-2009, 02:59 PM
JohnEJohn

How would I go about determining which value to use?

Also my Vcore values are set so if I change this should i lower these?. Never seen this setting before, first time DFI and Intel.

Some info on this would be great.

Thanks
