May want to check if your seated correctly or something though. Usually most use IBT AVX (from the very first page of the vishera club under additional software) and set to very high or extreme when testing. Generally this produces the best results and finds more instabilities (because it loads more of your ram + AVX has different libs). IBT AVX looks the same as IBT but runs differently (you will notice in duration time / gflops). The reason I mention this as it usually runs hotter then normal IBT (mostly because its on very high+) and most people on a custom loop (As far as i know) can easily push 4.9ghz still not hitting that peak temp (which you were close to). I am using my sig rig at 4.7ghz 1.52v able to keep it under 65 (too high but never reaches that even benching, only p95). Usually an h100i gets pretty close to exactly what you have there (which i would hope you can do better). Seems like something is not quite set right or something. maybe not enough thermal paste? I have also heard increasing PLL voltage can help some stabilize and lower temps.
Anyways hope I dont sound like I am dogging your rig I think its awesome, I just think you should be getting more out of it and something seems off. I could just be an idiot and it could be because of the full loop so If Im wrong anyone feel free to let me know. the rig is looking great though everything came together beautifully.
Also like your monitor set-up. Never thought of doing that. May take this idea from you once i get another monitor
. Leaves more room and less panoramic makes it interesting.
keep us posted once you get those new fittings and final setup
looks awesome, i keep going back and drooling
Ok, long reply time.
To start, I agree with you concerning my current overclock and I have a few theories concerning the cause. For starters, It might be a flow issue. As I mentioned earlier in the thread, I installed my pump in the bottom of my case. although this is arguably the best place to hide it away, I think that this placement is part of the problem (due to the weaksauce nature of the pump im using. currently the pump in question is a rather dated XSPC 720 pump/res combo), considering that with the pump placed here it is essentially pushing all of the water against gravity.
To illustrate this I will provide this rather sloppy paint diagram (the pic used is from awhile ago, namely before better cable management)

Either which way, the pump wont be an issue for much longer
next topic: IBT, pll voltage, and MOAR OC!
Ok, so on the topic of my current oc, I actually have had to reduce it after testing with that version of IBT
. It looks like I still have alot of tweaking to do.
As far as increasing my PLL voltage, i would love to try that suggestion, but as silly as it probably sounds, I could not locate it in my bios. I will make a thorough sweep in the near future (after the next rebuild I am going to shoot for a new oc from stock to see if I have better luck). Hopefully with the pump issue resolved, a pull set of fans for the AMS 480, a remount, and better tube routing we will see increased performance.
Next up: My monitor setup (what I use, what I like, and how I would/will hopefully change it)
Ok, so as far as hardware i am using 3x Dell 1905fp
panels. As you can see, they are a bit dated, but in my case that actually helped me. My original plan was to get a set of matching 1080p panels for use in a tri-portrait configuration almost exactly like the one i run currently using these panels. That plan fell through the floor when I decided that the money I would spend on the cooling system probably be more worthwhile than 3 monitors (to try to push with stock cooled 6870's. *shudder*). After :devil:looking around at what i had on hand from other projects/ collection over the years, I found two Dell 1905fp's, and after finding a third from a reputable dealer on ebay for $40, I decided to jump at the chance to pursue my goal of using tri monitor portrait eyefinity. So far, it has actually been pretty awesome. Up until now, i have been using a 1680x1050 panel for everything, and although i prefer 16:9 to 4:3 any day, the setup as-is has been relatively nice. I have had no issues with games using this resolution (once configured correctly, and excluding skyrim. Skyrim required modification to its configuration files manually using notepad), and everything has looked great thanks to the bezel compensation built into CCC.
That said, I do have a few things I would like to change. They aren't really in order of importance seeing as it would probably be best to do all of this work at the same time.
- De-bezel all three monitors
- Mount them on arms (either 2 on a double arm with one separate, all three on one arm, or 3 separate arms) to get them off the desk
- Spend some time re calibrating their color and contrast. At the moment they are all a bit off. Its not too bad, but it becomes apparent with some games, etc.

- Perhaps mod a small cooling fan into each monitor. The can get rather toasty.
So, for those who have made it thus far in this wall of text-esqe post, There is one redeeming factor!UPDATE!
I just received the pump (should I say pumps) that I will be using for the foreseeable future starting this coming week!
Its a Swiftech MCP35x2
I think its safe to say that after I install this pump flow rate should no longer be an issue
That said, we still have a bit more work to do. This weekend I plan on ordering the reservoir, and whatever other parts I to move farther towards my goal for the build (PPC's is doing a Halloween sale
, which I plan on taking advantage of!).
I would like to thank you all for your help and input, and look forward to more of it! (assuming you guys find my long 3am updates worthwhile
I have been having some artifact errors recently... dont really know the cause, although I suspect my Diamond 6870. Any help would be great. The artifacts only happen while I operate windows. In game, everything runs smoothly, excluding the odd frame drop here and there with Battlefield 3 and 4's beta test (although those games seem to be the only one with that issue.)
I am thoroughly confused as to the cause of the artifacts, and any help resolving this would be great.
Either way, please forgive any spelling or grammar based errors, its rather late at the time of (finally) finishing this update
