  1. I'm running out of places to put stuff so I need so sell of some of the stuff i'm just not going to get around to anytime soon. All items are in Vancouver, Canada. Prices are in USD. Buyer pays shipping / import (if applicable). 1. 4790k w/ retail box + stock heatsink - $125 Bought used on ebay run a few times in the z97 classified 2. G3258 + z97 classified - $160 Not a very good board for the G3258 so consider it a way to check that it the board posts 3. fx 6300 + 970 pro gaming aura - $150
  2. topic can be closed, bought from gunsligner
  3. Found some more hardware that I had forgotten about to sell so i'm upping this to $320 USD shipped.
  4. Looking for cpu or gpu pot for about $200 USD before shipping. Basically anything that will fit 58.4 mm or 53.2 mm nvidia gpus for a gpu pot and 115x, 2011, am3 and am4 for cpu pots. Not having either am3 or am4 is not a deal breaker though. I live in Vancouver, Canada and am willing to pay up to about $80 USD for shipping. Also willing to pay a bit more for specifically a green venom.
  5. Does anyone have the chipset drivers / MEI for xp? All the links I've found are broken or don't work.
  6. Finally have 20 posts so I can join this. Willing to cover international shipping to canada. Thanks for doing this.
  7. So even though I immediately killed the memory by being to happy to turn a pot heres how to volt mod this card and basically any reference ish 560ti since they use the same controllers. Gpu core power is a ncp5388. Look for an empty pad right below the ncp5388 based on the orientation of the text. The one on the left is what you want wire this to a 100 ohm pot since the feeback resistance is 2 ohms. OCP removal should be as simple as shorting over the resistor connecting ILIM to ROSC. Load line can be controlled with VFB and VDRP. I think disconnecting the resistor between the pins should remove all load line. On the other hand reducing the resistance from VFB to DIFFOUT should reduce load line but shorting is probably a bad idea. the resistance from ROSC to ground is switching frequency. Don't drop this below 10k as that is already 800kHz-1MHz. I wouldn't go below 15k as that should hit around 500-700MHz. Datasheet link: https://www.digikey.at/htmldatasheets/production/234279/0/0/1/ncp5388.html Memory is a RT8101/A. Look for the tiny dot on the chip to orient. I soldered directly to the pin. Feedback measured at 600 ohms so I used a 1M pot but 200k is also probably fine. This controller is really simple so theres not really much more to add. RT8101/A datasheet: https://datasheet.octopart.com/RT8101GSP-Richtek-datasheet-12527331.pdf Cap modding: This card is already really good on the capacitance front so I don't think it did anything. Can't say for sure since I killed the card before running any benchmarks checking to see if the mod worked. Also delidding is a really good idea. Watch this to see. Don't crush your memory chips though.
  8. y-cruncher scales nicely with memory settings but also requires the most stability of the hwbot benchmarks
  9. guessing this is the same mod as in here: what caps did you use for the input filter?
  10. I've been messing with this controller for a while now and have some basic voltage control for it. Full range voltage control and other details should be done by the end of the summer. The monitoring should be able to be applied to a 8266 as well. Most of this is based on the xml files detailing the i2c/pmbus interface in the evc2 software + disassembling/decompiling the raspberry pi voltage control software for the epower classified. I also verified this working with a arduino through a level shifter on a 680 classified through the evbot header. Since the epower classified has the controller at address 0x40 instead of 0x46 I modded the binary with a hex editor use the different address. Tested working with the asp1212 on a 780 dcu. Just use vset_mod linked. My test program for the raspberry pi is also linked. To compile it make sure you link with the i2c lib. Heres a pastebin of the arduino code i've been messing with: https://pastebin.com/HwaiEBRU Hopefully this should be enough info for anyone experienced with i2c to get basic voltage control. Once I iron out all the details i'll post a more complete overview with tools. vset_mod asp1212-test-rpi.cpp
  11. Here's the results so far with my 2 kits of 4000-16-16 1.4V ripjaws v: first kit maxes out at around 1.9v struggles more with 3900-12-11-11 190 tRFC second kit goes all the way to 2.0v does 3900-12-11-11 180/190 tRFC pretty easy both kits together run 3250 10-10 pretty easily at 1.75-1.8v still working on 3250 10-9 seems to be still quite a bit of lottery for high scaling but good bin for lower voltages. I got each of these kits for 250 CAD on newegg.ca.
  12. Default was 1.35 I think. I was trying to see how quickly the voltage rised when turning the pot to see what the non linear behavior was like.
