K404 Posted December 22, 2012 Author Share Posted December 22, 2012 If it helps any...... it does not apply to all nVidia cards. I just benched GT216 silicon at 1050MHz with 310.xx drivers Quote Link to comment Share on other sites More sharing options...
Massman Posted December 23, 2012 Share Posted December 23, 2012 What kind of clock limits? Quote Link to comment Share on other sites More sharing options...
I.nfraR.ed Posted December 23, 2012 Share Posted December 23, 2012 999MHz on the gpu. Quote Link to comment Share on other sites More sharing options...
Massman Posted December 23, 2012 Share Posted December 23, 2012 Even with software like inspector? Quote Link to comment Share on other sites More sharing options...
K404 Posted December 23, 2012 Author Share Posted December 23, 2012 Yup. It's a problem/feature for Fermi cards. I don't know about Kepler. Quote Link to comment Share on other sites More sharing options...
Massman Posted December 23, 2012 Share Posted December 23, 2012 So NV400 series. Â Documented issue? Quote Link to comment Share on other sites More sharing options...
K404 Posted December 23, 2012 Author Share Posted December 23, 2012 It's part of the Green Light program, I think. Quote Link to comment Share on other sites More sharing options...
W1zzard Posted December 24, 2012 Share Posted December 24, 2012 seems to be a driver bug.  when i set clocks higher than 1000 mhz, it will show no higher than 1000 mhz realtime monitoring, but clocks in gpuz will go up. the card also crashes around 1100 mhz which means the clocks get applied.  independent setting of shader clock doesn't work  Quote Link to comment Share on other sites More sharing options...
silva_br Posted December 24, 2012 Share Posted December 24, 2012 (edited) I'm also having trouble breaking the barrier of 1004mhz with drivers 3xx  only tested the gtx 560ti and you. both models had problems to pass 1004mhz. I even always runs at 1100MHz by setting 1004mhz even ln2.  sorry my bad english. using google translator.  Edited December 24, 2012 by silva_br Quote Link to comment Share on other sites More sharing options...

K404 Posted December 24, 2012 Author Share Posted December 24, 2012 (edited) Here's my testing. Same description as W1zz, but no change in score. Â Â Â Â I will load 28x series drivers and re-bench when I can*. Don't know if 1075 will run though, previous testing got me 1050MHz max.

K404 Posted December 24, 2012 Author Share Posted December 24, 2012 I'm WELL impressed with my multi-tasking.....also quite happy at getting 1075MHz to run     Well.... 310 drivers are more efficient- they are like having another 50MHz on the core.... then there is the boost from LOD.

benchmark.kz Posted April 28, 2013 Share Posted April 28, 2013 I had a similar problem with GTX 560 Ti and new drivers. I can set more than 1000, but MSI AB monitorings shows, that GPU Clock not higher than 1000 MHz anyway. Quote Link to comment Share on other sites More sharing options...

chispy Posted April 28, 2013 Share Posted April 28, 2013 (edited) I can Confirm you guys finding here too ! +1 it happened to me a few months ago, running GTX 460 clocks are locked to 999Mhz core even thought it can run 1060Mhz on older drivers, with drivers newer than 301.xx overclock is locked and limited by this new drivers to 999Mhz , also tested a few more cards as stated by CN (GT 430 , GT520 etc....) they are locked too. I think this limit impose by the NVidia drivers is hindering the performance for a lot of people Edited April 28, 2013 by chispy Quote Link to comment Share on other sites More sharing options...
Christian Ney Posted April 29, 2013 Share Posted April 29, 2013 Glad i am not the only one, the other day I thought I was crazy when I wasnt able to overclock any cards no matter what. Quote Link to comment Share on other sites More sharing options...
Xtreme Addict Posted April 29, 2013 Share Posted April 29, 2013 Does anyone has contacts in Nvidia to ask about it? Cause if it's purpose action, it's not good for community. Quote Link to comment Share on other sites More sharing options...
Christian Ney Posted April 29, 2013 Share Posted April 29, 2013 I just sent an email asking if it's a bug or a "feature", now waiting. Quote Link to comment Share on other sites More sharing options...
Calathea Posted April 29, 2013 Share Posted April 29, 2013 This is old, but bad, news. I have had no luck what so ever with new drivers above 1GHz gpu (999) on GTX560-448. I bet many people will swear about this in MOA B-Class Quote Link to comment Share on other sites More sharing options...
K404 Posted April 29, 2013 Author Share Posted April 29, 2013 Oh, FINALLY My find is being taken seriously. Â It is this simple: Â Â If someone uses FERMI SILICON with nVidia 300-series drivers, thery are capped at 999MHz core. Â I say Fermi SILICON because the GT630 uses GF108. Because it is 6-series, it needs 300-series drivers- so the MHz cap is there. Â OLDER cards- GT2xx are NOT affected. It is Fermi ONLY. Â There is your newspost Quote Link to comment Share on other sites More sharing options...
Christian Ney Posted April 29, 2013 Share Posted April 29, 2013 hehe, saw it only last week when testing some GTX 5xx cards Quote Link to comment Share on other sites More sharing options...
