Gone full quad red. multi gpu discussion and, need help (sort of); (will post results later)

post #1 of 12
Thread Starter 
next paragrath is mainly dedicated to my rant about multi gpu solutions in general and the NV vs ATI battle. unless u are interrested, just skip it.

First of all i wont to make a point related to the whole SLI crossfire discussion. i had PCs (and still do actually, i keep them as souvenirs) in maxed out confixed in most generations of cards, but i skipped the last ati and nvidia gen (580 gtx and 6970, if u dont count the alienware laptop that is). and i really want to get the message across: EVERY config had its quirks, for example my last builds 5970 trifire and quad 480 had driver related issues all the time, and enjoyed very little stability. and over the last few years surprisingly ATI multi gpu configs had less flaws on average (ore maybe more in quantity sometimes, but maybe no as drammatic in nature, unlike some of nvidia issues). so on the whole NV vc ATI multi gpu argument: i dont want to hear it. and like i said ATI seems to treat me better on average anyway.
also some more background info: i had experience with phase change cooling, built a tec chiller (which i still am pretty damn proud of as proof of concept) and of cource full blown watercooling with multiple pumps in series/ parallel, and whatnot. so why am i bragging like a cheap who re who just got tipped a 50? well, i just want to emphasise that in my experience , which is rather vast, water/phase/or tec cooling solutions made the pc even less usable in those situations. it is simple really: statistically the more elements u introduce the higher the risk of the system failing alltogether (matter of probability). so to people who want to enjoy their pc i recommend keeping it simple, unles u enjoy just building and benching (i dont game at all, just play some LOL on my laptop). there is just nothing like putting all the components, routing tubing, managing cables and getting a nice blue screen after startup! ohhh i had that one way too many times. troubleshooting is messy and takes a crapload of time. so from now on i am likely to skip on all that. Thank the Lord for Corsair H100-best thing to ever happen to a cpu.

rand continued:
Now to kick off with a story related to the above, i just bought a quad 7970 rig with msi big bang II mobo 8 gig dominators, 1500W enermax, and ssd, and H100 for cooling. all sitting in one of the most potent watercooling cases i have seen in a while: Xilence interceptor pro (obsidian has way better quality, but the wc potential with this one is just better imho. aaaanyway, slap it all together, check if everything sits fine, cables, bracket pressure on the cpu, etc.. push the power button and.... it gives me one blink and nothing! i was like ***FFHJKJHGFGHJH!!!!! ok, so i double chek everythink, take out the gpus, etc, still nothing. that really pissed me off, in the past i had numerous fails, but atleast i could diagnose those (mobo code, trial and error, testing individual components, etc, since atleast i had a hint of what wass going on) the worst thing that can happen is when the only simptom is just a dead pc.. it basically means either one of the main components was severely damaged (physycally or shock), and most likely it is the mobo or PSU since otherwise it would atleast start. so i was really upset and after double checking everything i pulled the second cpu cable off the mobo and voila! all running smooth! i just wanted to share this story because i am pretty sure most of you had one of those experiences, and i found the story ironic in the end.

so now to the actual matter at hand:
firts of all i have not been following the evolution of CPUs and decided to get the cheaper 3820 and overclock the shhhhhht out of it, without realising that unlike in the past more cores actually matter now in gaming. (i did not even realize it had only 4 cores). so i ran some test and got a little under 20000p un 2011 3dmark, which is very low (no OC yet). so i decided to run a few more to compare with equivalent systems with 6 cores. and the result is obvious: more cores is better on average. but most gpu heavy benches do just fine but what was very nice with this generation of CPUs is how simple they are to OC compared to before! all i did is i set multi to 44 and i have hassle free 4.4 Gz. that was just magical!. so i have a few questions:
i have not been benching in a while, what would be the typical checklist now in terms of best OC software and ati catalyst tweaks prior to benching.
any links to maxing out 24/7 3820?
i think i have the GPU OC more or less figured out, just wondering wether you think i can improve airflow to the gpus? maybe spacers between the cards, or a fan blowing from the side or upfront, or that make no difference at all?

point of this thread is mainly that i want to chat while i bench tongue.gif

Quad 7970 with single 1500w PSU as a benching rig? I guess this is just for mild OC benching funs.

Lol! True dat! I was writing on a big screen ant the block of text seemed tiny, I did not realise!


As for the 1500w psu, like I said it is mainly for benching on air, so that is enough, and btw, 1500w enermax can handle more I think. In my experience with enermax their psus are usually rated a bit below what they can handle (unlike most other brands). Really solid.

I will bench a bit but this will be my 24/7 rig, so no more fancy cooling solutions, as I have explained above.

As for the GPUs drivers + OC with third party, here [Fixes] Catalyst Drivers Error & OC & Eyefinity & General Issues

 

Those 3 links above should get you somewhere to start with what's going on lately.

And thx some more!
I have a slight issue: I disable ULPS but one card out of four seems to be do clocking at rest. Any ideas? Any way to double check ulps? Maybe it is not disabled on 1 gpu? I have it set to 0 on all 4 though..
post #10 of 12

To make sure all are set to 0

 

To turn off ULPS;

1. Go to regedit (start > search programs and files > "regedit").
2. In drop down menu: find file > type "enableulps".
3. For
ALL instances (keep pressing F3) change the "1" value to a "0".
4. Reboot PC.
 
Note: disregard "enableulps_NA"
 
Another new thing intoduced in 7000 series is ZeroCore Power State, here post #22. Check it out so you know what to identify in case of errors and what to rectify.
