Y500 SLI Overclock Thread

Recommended Posts

Y500 650M Overclock Thread

I can not find any of my 3dmark keys... EVGA deleted them I guess. So I am using Valley from Uni Engine.

I so far have a stable clock at

969mhz Core

2500mhz Mem

Score on Extreme HD 1046

Stays around 70c. Increased playability of games a whole hec of a lot. But I have noticed small artifacts so I may either see if its throttling down, or if it just happens to be to high a mem clock maybe lower the cor to 950 and keep mem up. Let me know all your experiences!

I did this with Afterburner, and of course unlocked bios. Nothing special though. No CP changes, or driver tweaks. I used to be much in to benchmarking but now I look at it this way, my car may go 150 but really where can I use it at that speeds?! So playability is where I am at on this project.

I will update this accordingly, I may get a cooler, put IC Diamond compound on the parts, and ThrottleStop it. These cards can run good around 70-75c without much problems. Update your findings here as well!

Highest Stable CORE 1109mhz MEM 2400mhz

Unigine Valley Benchmark 1.0

FPS: 26.1
Score: 1093
Min FPS: 7.5
Max FPS: 48.9
System

Platform: Windows 7 (build 7601, Service Pack 1) 64bit
CPU model: Intel(R) Core(TM) i7-3630QM CPU @ 2.40GHz (2394MHz) x4
GPU model: NVIDIA GeForce GT 650M 9.18.13.2723 (2048MB) x2
Settings

Render: Direct3D11
Mode: 1920x1080 8xAA fullscreen
Preset Extreme HD


I am highly satisfied with these numbers (no throttlestop). It does "hiccup" some, but out side of benchmarking it doesnt, With throttle on, I gain .3 fps.... highly illogical. However I will be tweaking things to lower the temps a bit.

Haven't had a chance to unlock the bios so I can only get to 925mhz core clock and 2854mhz memory clock. Any higher on memory and it starts causing issues. I figure once I can up the core clock higher I will have to lower the memory clock to avoid issues. I'll let you know once I get the bios flashed.

Ive been running it stable with the above config. No issues. Like any overclocking its luck of the draw. I have what I would call great overclockers. Not wondrous but great.

Do you have some info on any performance gains in actual games?

 

650M SLI stock - 790 MHz core @ 1V, 1000 MHz memory

650M SLI OC - 1150 MHz core @ 1.05V, 1125 MHz memory

 

Sleeping Dogs: Definitive Edition

42.2 FPS stock vs. 57.4 FPS OC (+36%)

      After spending significant time and effort to obtain "DC" screen for 8770w (which is essentially a regular IPS panel with fancy board that converts 8bpc LVDS to 10bpc DP), I have finally got and installed one. All works great, except of the one problem...

      It has pretty bad banding / posterization in lower shadows. I have tried profiling it in different modes (full range, sRGB, rec709) - issue persists, and it indeed shows only in the lowest part of the characteristic curve. Mids and highlights are represented fine and show low deviation from reference values.

      GPU is HP K4000M, Nvidia drivers installed "as it is", video-card is identified without a hitch.
      Banding was not present with the original TN panel using the same GPU.
       
      While checking a software side, I have noticed that Win10 has bit depth set to 8-bit...
       

       
      My initial reaction was, - "Easy, let's change it in `nvidia-settings` and we're all set":

      ...but that would be too easy, right? After selecting 10bpc and clicking "Apply" screen went off and back on, only to show that depth stayed at 8bpc. Repeating the above few times yielded exactly the same result and I'm not in a hurry to meet a cliched (and laymen) definition of insanity.
       
      Let's check GPU-Z. So far so good, nothing unusual. Notice the highlighted BIOS version and subvendor string:
       
      Time to delve into other tabs. We are running WDDDM v2.4 which supports GPU dithering, but hey... BIOS version has changed!
       
      Briefly back to `nvidia-settings` to check what is reported by vendor's own utility:

       
      So far, we have two strings for BIOS version:
      80.04.5A.00.02 (let's call it an "A") 80.4.33.0.37 (let's call it a "B")  
      Notice how 2nd one seems to not follow hexademical notation. Lastly, "NVIDIA BIOS" drop-down, reports "A" version:
       
      ...and monitor section which confirms that rig is indeed capable of 10bpc, but currently running at mere 8bpc:

       
      Windows "Adapter settings", reports version "B". It's 2019, diversity is a must.

       
      "NVidia inspector" is of the same opinion:

       
      Now, let's use some seriously legit tools and check-in exported BIOS file in `nvflash`:

       
      Here we have two three interesting findings:
      Reported vendor is Dell, not an HP. See this link for details. BIOS version is back to "A". Have I already mentioned diversity? MXM module uses MX25L2005 flash storage in WSON-8 packaging. If things go real nasty, we should be able to rescue a patient via Pomona clip and external programmer.  
      Loading the same file in "Kepler BIOS tweaker" confirms the facts:

       
      EDID settings, courtesy of NVidia Control Panel. Hex dump can be found at the bottom of this post.
      ...Shall I be worried about "60.02Hz" refresh rate?
       
      To summarize:
      Why two different BIOS versions are reported? Anything to do with UEFI (e.g. HP is sideloading its own during boot)?.. Why two different vendors reported? As far as I remember, this is branded HP GPU. Where to get "clean" BIOS of K4000M for future experiments? Ideally from 8770w equipped with "DreamColor" panel from a factory.

      Hi guys, bit of a rookie to the whole EGPU scene. Currently I have:
       
      - MacBook Pro 2015 13inch (3.1GHz Core i7 16GB RAM)
      - Razer X Core 
      - Apple TB3 to TB2 Adapter
      -  TB2 Cable (Cable Matters)
      - 23inch AOC External Monitor
       
      I am wonder about what graphics card to get to run X-Plane11 with high graphic settings?
      I have purgewrangler set up and ready to use with an AMD graphics card, but am also open to the idea of an Nvidia graphics card.
      Any advice appreciated. I did not buy a Windows PC as I need a Mac for various other things and wanted an all-in-one laptop.

      Hi, I'm having problems trying to connect a GTX 750 Ti to my Lenovo T420 using the dock EXP GDC Beast (express card version).
      My laptop: Lenovo T420
      RAM: 8GB DDR3
      CPU: Intel Core i5 2520M
      GPU: Intel HD Graphics 3000
       
      My problem is: if I plug the express card and I turn on the laptop it doesn't boot up and the screen becomes horrible, with coloured pixels and a sound like "bip-bip".
      If I try plugging the express card when the laptop is already turned on it sees the gpu, but if try installing the drivers I have to apply the modifies restarting the computer.
      I hope you understood my problem (I don't speak English very well).
      Please help me, It's making me crazy!
       
      EDIT: I didn't say that if I plug the express card when the pc is already turned on, in the device menager there is "Error 12" on the gtx 750 ti
    • By Kel
      I got the exp gdc beast 8.5 got all the connections right... laptop boots up... fans turn on the gpu.... device manager detects gtx 1060 with a “ ! “ in a yellow triangle. Now what to do.... i tried to do the bios mod.... but realised that i have 3.07 version. 
      Questions-
      1 is there any way to get this done without the mod?? 
      2 if mod is the only way... kindly help me with step by step instruction in laymans terms... i m not a techy... so i might not understand technical terms.... altho i am interested... but learning yet. Please help.
