Fixed, realized that with this bios, adjusting voltage using voltage tool does not report correct voltage, although there is a change

I didn't realise that the there had to be the mainboard window open, although the picture of my rig should show that I don't have an LN2 board (and I don't have enough status to even warrant getting an LN2 board) is that alright? Next submission will have it though

Looking to pick up 2-4 8gb sticks of DDR3 double sided ram that does 2800 or beyond. Willing to go as low as 2666.
Many thanks

So I've been trying to OC my 4790k for this month's gigabyte OC thing, and I've run into a lot of issues trying to OC particularly my BCLK but also my uncore. I'm on a Gigabyte Z97X-SOC Force, so I should have more than a capable mobo, also with an AIO
At 100Mhz base, I can do 4.8@1.32-35v core, which is pretty average. I can't change the strap at all, unless I downclock the bclk to result in a 100mhz base anyway (1.25gear, 80base). I can't really go above 102.5 Mhz on the base clock if I'm not touching the strap, and even then, it's quite fragile and often crashes. Even 101.5 is iffy.
It's not the memory, because I've tried 2 different kits, and set multipliers from 8 all the way to 20 and it still crashes.
I've played with all the voltages, i.e. modified PCH, VIN, VRING, VCORE etc... Followed sin's guide and also tweaked them myself to try get it more stable so that it actually boots... but it doesn't.
Used the OC trigger switch to no avail. Tried all the different SATA ports and mainly use the external sata chip on the board because I've found it's more stable. Tried a number of different GPU's in the bottom slot (and all the other ones) to no avail. OC'd in the bios and also with GTL. No difference. Checked all the voltages with a DMM, they're good. Tried 6 different bios's with a no go on any of them.
Uncore doesn't like to go over 4.2 and there isn't really much more to say about that.
I've read and researched a significant amount on this topic and a lot of people seem to be having much better luck than I am, I'm not sure if I'm doing something wrong or if the chip is just bad. Mind, 4.8 isn't the worst if I'm stuck at 100Mhz bclk, but I don't want to put this chip sub zero and waste a bunch of LN2 attempting to get a higher base clock if its crap. And it certainly doesn't cut the cake attempting to beat out other people OCing on ambient either
I've just feel I've wasted a lot of hours trying to OC without getting anywhere, I've spent a painstaking amount of time changing things setting by setting and there hasn't really been a difference. I mean, I can get the same BCLK (102) on stock voltages. Does it sound like I'm doing something wrong? Any help would be great, thanks

So this gave me a bit of an undue headache because of a bad joint to ground, and I was wondering why nothing was working
Runs an RT8867A, data sheet attached. Pull one of the purple points to ground (pin 6) with a 20k - 40k ohm pot. Do I even need to do the shunt mods?
A quick run proved easy points on a $25 card running stock cooling, should be good under LN2
But I got beaten by 4ms
if only I knew how to tweak gpu pi.... -
Aha, it was just a bad joint to ground.... SMH
Thanks though!

What day is the OC event usually on for PAX? Booking tickets and trying to decide if I can leave on the Sunday. BTW, the world tour site is a little off for dates. PAX is from the 27th to the 29th, not the 3rd to the 5th

People so obsessed with small things...

got some pot coming in teh mail :^) thanks vince
is it a sign??? are they to be paired together? or perhaps the 1080ti
-
I'd love to play around with some of the lower end parts. Hopefully they didn't laser off the cores, which would be great to try my hand at firmware hacking to attempt and unlock them (or alternatively just learn more) and even if I can't do that, I can still OC the chip! Win win

I don't actually know 100% if the sfx holes are correct. I looked at three different dimensions for sfx and they were all different from by a little bit. I think it should work though
-
Added the middle screw
-
Wow, those holes are off, sorry about that, I don't have a supply to test it for myself. I took the measurements off some other guys work (what a nutter haha, everything is off)
Butttt, I did update it now! I got the source files for the OBT, scrapped my previous design, and retook my measurements.
The new design is .5mm thicker in on the PSU faceplate and fully reversible, so you can have the PSU in any direction, all the threads are the same (I hope they were alright to thread?)
All nice and centered too!
As you can see, I've no idea how to use rendering software, the lights just went nuts
.STL and .SLDPRT files in the zip!
-
Come to computex instead
That sounds like a great idea, I'll see if I can make it

Wish I could go to CES but... Australia

Thanks buildzoid, I fixed the issue, it was ULPS. It didn't matter if I had it on or off when OCing one card, but it needs it disabled when OCing 2 cards.
Trixx v5.2.1 doesn't work with the HD 7950 (it crashed like crazy on my system) but v5.0.0 works fine. Thankfully Trixx is the only one that told me I needed to disable ULPS, works great! Voltage control is now unlocked up until 1300
Although the second card doesn't go very far, hits a wall at 1025MHz on the core whereas the other goes up to 1260MHz. I think I can get some more out of the worse card on its own but I haven't tried it in a long time in a single config
-
I cannot change the voltage of the second GPU in crossfire. Wondering if I can do a BIOS flash or if there is a special tool to be able to do this? Or if my only option is volt modding the card (which I intend to do anyway at some point in the future)

Here is the SFX to ATX bracket that was requested in the most recent OCtv stream (great stream btw)
It has a chamfered edge on the outside for those aesthetics and holes to be self tapped by screws as this is meant to be 3d printed. I'm not sure how well it will hold up a power supply so if it needs to have more structural integrity, just let me know.
I can make adjustments for one to be CNC'd if people want it. With proper clearances and threads.
I can also make any other parts people want if I'm given dimensions and measurements!
I enjoy the work and it doesn't take me too long (it's fairly basic)Download has both .stl and .sldprt files
Edit: Also, let me know how the self tapping goes
