the board looked fine from top. but when i changed tim the board was caked in dust behind the heatsink.
the prices i paid for things in the pc. would make amd budget pcs look expensive.

Probably the VRM has been stressed a lot on the PCB and can't handle as much as current.

core probably has degraded?

Maybe, not sure since many variables can come into play.

hello

new to GPU ocing but not to CPU lol, not complete newbie so be gentle please

anyway running this Gigabyte card low profile and having no external power connector on it


trying to achieve 2 different things

1) running the card cooler during no to low load activity
2) OC the card on air beyond the 1255Base/1333Boost I have achieved stable so far

I added a F8 fan on the side of the card to cool it down but still its sitting right now at 35degC while just surfing,not quite happy with that

as per the OC topic,I am sure the card has more to deliver abd would like to release this potential by altering Voltage/Power restrictions

Now to cut long story short,I am running W10 and tried an handful version of the nvflash software either in DOS or windows to flash a modified rom (Voltage and power table) that I have set with Keppler or Maxwell weaker software

I am getting the same error on and on as below

Error Code:8 BCRT_ERROR_CODE_BODY_SIGNATURE_MISMATCH
VBIOS Signature Check Failed.
Error Code:7 BCRT_ERROR_CODE_BODY_FNV_HASH_MISMATCH
VBIOS image failed certification sanity check.
BCRT Error: Certificate verification failed
ERROR: ERROR:BIOS Cert Verification Error, Update aborted.

but if I tried my original BIOS backup,it works like a charm.....

I disabled the NVDIA card in device Manager, tried to unlock EEPROM protection etc etc but no joy

can anybody provide some sort of guidance on how to overcome this issue?

Idle temperatures don't matter. If you want to lower them for some reason, think about better cooling. The heatsink, in my case, was literally just a slab of poorly machined aluminum. As for your other issue, you should try using an older version of nvflash.

Should juat proabably kill it quick.

always flash your own bios saved from gpu z. probably cause of error.

i did back up my original BIOS from GPUZ indeed and I can flash it with nvflash tool without problem. thats the modified BIOS either Voltage or Power table that I have created with Keppler or Maxwell tweaker that is getting me the errors I am mentioning above.

to make it more clear about temperature issues, thats not the idle one which is worrying although I consider it being high but the actual Temp under load during gaming. Iwas hitting 80degC very easily so the additional F8 fan I set in front of the card helped me to reduce max temp to 72-74degC in the same condition but I would like to see if I can reduce this bit further from BIOS tweaking

hope it makes more sense now

You could try taking the shroud off, removing the whiny stock fan and mounting two 92mm fans on the grill next to the card. Use some spacer to get the fans a tiny bit away from the grill to reduce the noise.

Power Target is very easy to modify, but the card already runs at 38.5W at stock. Go any lower and you'd probably be throttling constantly. You can modify voltage. I don't quite remember, because it was a while ago, but I think it's voltage no. 53. Be sure to confirm before you actually do it, it's in this thread some pages back. I don't know how much use you'd get out if it because I haven't tried undervolting. Going from 1.143v to 1.2 netted me only a couple Mhz steps more. If you want your card to run cooler there's no other way about it, get better cooling.

EDIT: see post #2938 in this thread on how to undervolt

ok thanks again, maybe I am trying to achieve something impossible from a software solution point of view but I have no time to do DIY stuff on the card TBH I spend too much time on my rig already

so I am going to have another thought on the topics,I cant modify my BIOS anyway right now so I am kind of stuck.....
post #3000 of 3179
Thanks again for the old NV flash ... was able to get 1450hz on the core and 3200hz on the ram with 50+ mv at 60c on load, but I guess the card never wants to go above 80% power most of the time it's at 50 -60 wonder what would happen if it would go to 100% maybe I could hit the 1500 on the core lol...

here the gpu benchmark it has built in
