Hi guys, first of all thanks for this post, after watching the video from Level1Tech I got a couple of Tesla k20x for a ridiculous price, and after tinkering with the cooling system I was not happy with the frequencies, so I decided to go for the titan mod, and now I want to share my experience: after replacing the 35k resistor with a 25k one and removing the 45k I got id 1031, and no driver was working, so I decided to put back the 45k resistor, but since it got lost in the process, I put a 56k instead, and to my great surprise I got id 1005, and the driver for the gtx titan magically worked! I have done some tests on a pc with an i5 4690 and the gpu is boosting to 1032mhz, and I got 4000 with furmark (1080p preset) and ~3000 with unigine valley (everything maxed out with 1680x1050 res), which are in line with a gtx titan. I will post some pictures as soon as I can.

Hello, final update: soldering the smd caps missing along the pcie lanes didn’t work, so my p104-100 get still recognised as a pcie 1.1 x4 card, so the pcie limit is imposed at software (bios/driver) if not even at chip level..
-
just a little update on my attempt to get a full pcie 16x working connection on a p104-100 by soldering some caps missing near the pcie lanes: I got all the tools, I did some practice, and I managed to desolder one of the caps next to the empty spot, which should supposedly have the same value of the ones I will have to solder, the only problem is that I can’t find a cap with the same package size and capacitance, and I need about 20 of them! I have already salvaged an old smartphone and tablet boards, and an old graphics card, but it seems impossible to find a 0.22uf mlcc 0402 cap, so probably I will have to buy them new, and wait until I get them delivered...

Hi, not sure what could be the problem, but you should be more specific: which card (model and brand)? which o.s.? which driver? is the vbios modified? does the card work for mining (with claymore’s miner for example)? anyway if you are on win 10 and you haven’t tried yet, try to 1 - disable windows automatic driver update 2 - use d.d.u. in safe mode to clean up any trace of nvidia drivers 3 - reboot in normal mode 4 - run a registry clean with CCleaner (optional but suggested) 5 - install the driver (so far the best one for win is 417.22) 6 - disable the card in Device manager 7 - modify the two keys in regedit as in the video 8 - re-enable the card 9 - reboot 10 - open the nvidia control panel and select the card as performance card 11 - on power saving setting in windows set up performance mode (maybe a redundant step, but you never know) If this doesn’t work, your last chance is try the same procedure on a clean win 10 installation, if this doesn’t work either I guess there might be a problem with your card.

it looks like some caps are missing at the bottom, if you follow the lines that come from the pcie connector you will notice it..anyway I am not so sure you are actually running it at pcie 3.0 x4, your benchmark results should be much higher (over 2500), but it maybe be due to the fact you are using opengl..isn’t there any tool in linux to benchmark the actual bandwidth of pcie cards? the only one I could find in windows is included in the 3dmark pro version suite, which costs 25€ on steam..
-
I am on win 10 using driver 417.22 (just the registry hack, no mod to the driver) I am not very good at Linux unfortunately..anyway today I got the hot air station delivered, but I still need some good flux and the cap tester, hopefully by the end of the week I should be able to try the cap mod on the pcie traces..by the way, do you have any chance to check if your p104 has some caps missing near the connector like mine does? I have seen some pictures of asus and gigabyte models which seems to have them soldered, but are still working at x4 1.1

ok, in my case I tried to oc the core +200 (2100) and the memory +500 (5500) with msi a.b., the fan curve works, but the minimum is set at 50%. So far it works like a charm, I got 2200 heaven score with oc (compared to 2090 without oc) at 1680 res, now I am waiting for some tools I ordered to try and solder the missing caps along the pcie lanes.
-
Interesting, actually my score is a bit higher since it was run at 1680x1050 (ultra settings, extreme tessellation), I guess yours was done at 1080p, which is the standard, so the results are pretty much the same..what’s strange is that in your case it says pcie 3.0 x4, so probably your report from gpuz is wrong, or it is mine..I am more keen to believe that it is yours since according to this article from techpowerup a gtx 1080 running at pcie 3.0 x4 loses only 4% of performance on avg, and about 30% at pcie 1.1 x4, which is about what we get: your p104 ~1800 VS avg 1070 ~2400 = 25% loss of course there are a ton of variables, unfortunately I haven’t been able to find a benchmark able to measure the actual pcie bandwidth yet. Anyway, which bios are you using? Is it stable (no throttling or fans acting weird)?

A little update, in case someone should be interested in improving the pcie capabilities of a p104-100: First, I did a cleanup of drivers, reinstalled everything, and now I get a score of 2100 on unigine heaven (before it was 1400), while a standard gtx 1070 should be in the 2300/2600 range with the same settings, so getting close, even if gpuz still says I am running the p104 at pcie 1.1 x4(probably unigine heaven is not stressing the pcie slot much, I need to do other benchmarks). Then, I noticed that some capacitors where missing along the pcie traces on the pcb here is a picture of a zotac gtx 1080 mini, which appears to have exactly the same pcb so, at least in my case with the ZOTAC P104-100 the pci-express limit is at hardware level, the good news is that it shouldn’t be too hard to get some caps soldered, hoping that the limit is not imposed in the bios/driver as well

Hi all I found an online shop selling a Zotac p104-100 for 99€, I couldn’t resist and I ordered it. Following the instructions from previous posts I managed to make dx12 work in a 4690/h81itx system with drivers 417.22 (registry mod only) pretty easily, and I even manage to unlock 4gb of extra gddr5x (pretty easy as well, just flashed a generic nvidia bios found on techpowerup). Unfortunately, as someone already pointed before, the card is stuck at pcie 1.1 x4, I run a test with Unigine Heaven, and I got a score of around 1300 (when a gtx 1070 with the same settings scores almost double), and it is a real shame, since the raw performance of this card should be incredible (better than a 1070). Now I am trying to find a way to unlock the pcie slot, which I believe is something that should be done via bios, if only a pascal bios editor existed: everyone says that it’s impossible to decrypt it, but in another forum I found this tread , if you scroll down at the bottom you will see a picture of some kind of software called “NVbiosEditor”, which is modding a gtx 1080ti to improve the ram timings, and suddenly I feel that modding a pascal bios is not so impossible anymore...what do you think?

Hi all, a trustworthy online shop in EU where I live is selling some Zotac p102-100 for 99€ brand new, I guess they just want to make space on their shelves. I ordered one to fiddle with, and I was curious about the die on it: is it a gtx 1070 with gddr5x, or a 1080 with some cuda cores disabled via software? I know that pascal bioses can’t be edited yet, but it would be interesting to be able to unlock the remaining cuda cores as well, considering that someone already manage to unlock 4gb of extra gddr5x which were disabled via software (bios)..

Unfortunately where I live (Italy) ssd prices are a bit higher nowadays, and anyway I have to get this pc done with what I already have at home (it’s not for me, and the mandatory requirement is ultra low budget), anyway thanks to everyone
-
ok, thanks to everyone for the very quick responses, I usually go for bigger ssd with the classic setup that everyone suggested, but in this case I have to work with what I have and I was worried that using such a small ssd as boot drive it would fill up very quickly because of windows updates and browser cache (as someone pointed out) so I was hoping that caching could be a solution, but it looks like most people do not see it this way

Hi everyone, I am new to the forum, I didn’t find an “introduce yourself” section, so I am firing my question here straight away: I am setting up a cheap general purpose/light gaming pc, and I am gonna use a 60gb Intenso sata3 ssd+500gb 2,5” (5400) hdd as storage, do you think it is better to install win10+basic software (browser, winrar, openoffice, gimp) on the ssd and redirect the rest (user’s folders, games, big applications) on the hdd, or install everything on the hdd and use the ssd as cache with intel rapid storage technology (or any better free alternative, if you know one)?
