problems with 275gtx sli

Mr. May · 20 Jul 2009 at 16:40

just got 2 275 gtx installed them in my pc and they work in sli ran a few benchmarks and the screen was slightly flashing yellow and blue then it crash i rebooted

then windows areo would not work and lookied in device manager and it said that my 1st 275 had a code 12 inserficient resorces to run and the other said code 43 which said windows has stoped this device from working

so i reinstalled the nvidia drivers and there is only one now in device manager and no sli option ?? so got the old beta windows 7 drivers and they dont work just brings up an error

update:just tryed each card on its own in each slot and they work fine getting about 54.1to 54.3 fps average but when i put both in work fine its only when i put sli on and it goes pete tong and i get the same fps and the screen flashes slightly restarted it and only one card is showing again

any help would be most thankful

what power supply you got?.

Mr. May · 20 Jul 2009 at 21:07

thermaltake 850 watt

Four independent & dedicated +12V rails(12V1,12V2,12V3,12V4) provides superior
performance for PC system (combined loading of 62A).

shouldnt need more that that should it ?

I would try a complete OS reinstall, unless it's too much hassle for you.

D.Roberts · 20 Jul 2009 at 21:30

i was gonna suggest it to i was gonna say a diff os alltogether like xp.

Mr. May · 20 Jul 2009 at 21:32

ive ive already done that 4 times read the second comment it had windows 7 then i put xp on then windows 7 again then the latest windows 7 then put xp back on it still the same problem :confused:

when ever i do a bench loada game or it loads any sort of 3d app it starts flashin a slight yellow-blue tint on the picture and iam seeing no benifit in sli btw this only happens with sli ON..... if i disable sli it works fine :mad:

Only other thing could be your motherboard not handling SLI properly, only way to prove is put your parts in another board

Mr. May · 20 Jul 2009 at 21:43

ive just had 2 9800 gtxs before these working fine in there so it cant be my mobo and i havnt got another sutable machine

Rroff · 20 Jul 2009 at 21:56

Sounds odd... unless the pencil mod is causing issues...

Other than that it is possible that you've run out of IRQ resources but I thought windows 7 handled that differently... or it could be a power problem - PSUs can still be working fine but at a hugely decreased power output sometimes.

EDIT: Are you using a recent BIOS version on that board and have fast CPU reads turned off? as there is a known video corruption bug with that motherboard that can cause similiar problems.

Mr. May · 20 Jul 2009 at 22:02

the pencil mod is only for the cpu voltage am i right ? and what is fast cpu reads i dont get this bios very well my 780i striker bios was brilliant shame it was a **** board lol and i dont know how to change the bios

the psu could be gettin streched but a i7 rig with 285's in sli only pulls 600watts according to reviews any advice on how to change the bios and the cpu speed thing
i would be over the moon

edit: found the motherboard info and it reads

version 2.0
model C72M51XECRB
BIOS LTD 6.00 P

PCI-E BUS 2500MHZ
PCI BUS 33MHZ

bad news iam afraid updated the bios and my pc has gone proper pete tong i think it has corrupted both my harddrives as they will not boot tried to reformat windows 7 and it is nothing but errors so going to try xp then its of to bed as i got work at 7 any one who has been through this any help would be a huge bonus

update started installing xp formated the harddrive put the 1st lot of files on then it just keeps booting from the xp disk and if i force it to load from harddrive it says

DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER

Try replugging it.

Mr. May · 21 Jul 2009 at 00:02

replugging what ?

Overslop · 21 Jul 2009 at 00:05

The hard drive. I have got around that that error by doing so. If that doesn't work, try chaging the SATA socket it is plugged into.

Mr. May · 21 Jul 2009 at 00:07

whilst it is on? i have just swaped them over (whilst it was off )but still booting from cd even when i force boot it from the harddrive

Overslop · 21 Jul 2009 at 00:08

LoL, not whilst it is on!

Try resetting CMOS after they have been swapped over and try again.

Mr. May · 21 Jul 2009 at 00:13

reset it still booting from cd and wont let me reflash bios

Rroff · 21 Jul 2009 at 00:15

Did you reset the CMOS after teh BIOS flash?

Updating the BIOS can't directly corrupt the HDDs - its possible some BIOS settings changed for the HDD settings or the flash partly failed -

Overslop · 21 Jul 2009 at 00:19

Not looking good then...

I would still try tinkering around a bit. I've got that message a few times before and always overcome it somehow or another. But it is quite possible that your BIOS update has caused a hardware malfunction. However, I'd say it's much more likely that your mobo has died, rather than both your hard drives.
