Sh1nRa358 Posted February 25, 2015 Share Posted February 25, 2015 So what's up with the new drivers:341.44345.20that were just released?Did they block this trick? Do they perform better than one in OP? Or is it a real security patch with no strings attached? Quote Link to comment Share on other sites More sharing options...

Sh1nRa358 Posted February 25, 2015 Share Posted February 25, 2015 I could still overclock so I guess they aren't nerfed drivers Got a -14 in firestrike though compared to the 344.80 drivers so I guess I'll still stick to 344.80 until the real new drivers come out.

Only achievable using the kernel mode driver module with matching nvapi.dll version, allowing OCing without breaking Modded vBIOS unlocked options, v346.87/r346_00_186 instead.

slarlac249 Posted March 14, 2015 Share Posted March 14, 2015 I didn't have to use a matching nvapi.dll, overclocking worked with the just kernel mode driver for me and there were no blank screens. i guess your solution was about more than overclocking from the looks of it.

NV Inspector, MSI Afterburner and Precision X won't work correctly unless nvlddmkm.sys & nvapi.dll are v346.87, taken from my previous 780M/LGD02C5 blank screen fix(2) broken OCing options. This result is not achievable using nvapi.dll v347.xx/clock-blocked. Quote Link to comment Share on other sites More sharing options...
WJames Posted March 19, 2015 Share Posted March 19, 2015 Thanks much for your efforts, @J95. The driver tweaks worked perfectly! 1 Quote Link to comment Share on other sites More sharing options...
J95 Posted March 19, 2015 Author Share Posted March 19, 2015 Thanks much for your efforts, @J95. The driver tweaks worked perfectly!No problem, latest v347.88 restores OCing but performance isn't good. This mod works with v347.88 without issues. I'll update OP.

WJames Posted March 20, 2015 Share Posted March 20, 2015 Anandtech has a good article on overclocking a P770ZM: AnandTech | Clevo P750ZM: GTX 980M Overclocking InvestigatedThe article mostly focuses on GPU overclocking as the author notes that overclocking the 4790K may introduce some cooling issues. I found the section on power requirements very enlightening. I think most people - myself included - assumed that a 230W power supply would be more than sufficient. However, the power usage charts show otherwise. If you are heavily overclocking both the 4790K and the 980M, you are probably exceeding the power ratings on the 230W block.

jaybee83 Posted March 21, 2015 Share Posted March 21, 2015 indeed, which u can also see in the batcave OP where i did power measurements with everything overclocked check my sig for that ps: its the p750zm btw, not the p770zm Sent from my Nexus 5 using Tapatalk Quote Link to comment Share on other sites More sharing options...

They definitely show that a hard core overclock with the 230W PSU would be pushing the PSU's limits. I wonder if the "whine" that some owners are reporting is because of they are exceeding the power rating on the PSU. *shrug* I was concerned about noise, but my unit has been very quiet. However, my CPU is locked and undervolted at 4 GHz, and I only marginally OC the GPU. Other than an audio driver issue I had early on, this unit has been flawless.

x7007 Posted March 26, 2015 Share Posted March 26, 2015 How far did you manage to overclock a 970M ? overclocking the Gpu clock is dangerous more than the memory and can cause some Micro Stuttering / Slow Performance fps after some time in a game even if the benchmark worked fine. with drive 347.88 the overclock works Quote Link to comment Share on other sites More sharing options...

OvenRoastGT Posted May 3, 2019 Share Posted May 3, 2019 Hello, is this driver downgrade the only way to restore overclocking without changing the vbios? Quote Link to comment Share on other sites More sharing options...
numecont Posted December 8, 2020 Share Posted December 8, 2020 Im on windows 10, i guess i'll have to mod my vbios and hope for the best! Quote Link to comment Share on other sites More sharing options...
