gtx 760 overclock

06 March 2017 - 11:19 PM

i had written a long rave about tweaking the video settings, but i fucked up a keystroke and deleted it all... i hate that

 

long story short, i thought the elpida vram was crap in my giga gtx 760 (and most other situations), until i bumped my main ram's vdimm to help the ares handle the high clocks i demanded  : 2133 with latencies at 10-12-12-31 - it's meant to do 2400 at 11-13-13-31, but rated to do it with 1.65v, and my marginally less speed (the highest the sandy is capable of comfortably doing) was at stock 1.5v, which i gently nudged to 1.54, the smallest increment the bios would allow

 

previously gaming would crash the driver, but not bluescreen ... but occasionally black screen, and i thought the vram was the culprit, as keeping it almost stock was much less inclined to do so; rig specs below, and the impetus to overclock was the upgrade to u2515h from the previous u2410 which was pretty schmick at stock for the 760, but the move from 1920x1200 to 1440p is a major increase in required grunt

 

i5-2500k 4.2ghz @1.225v / megahalems / gigabyte z77-d3h / samsung 850 evo msata 250 / 2x8gb G.Skill ares @ 2133 / asus xonar d2 + klipsch promedia ultra 2.0 + ath ad700 / Lian Li PC-A17B & corsair hx750i & noctua fans / gigabyte gtx760 oc windforce / dell u2515h

 

wow, did i underestimate the elpida... it's clocking like samsung despite gpuz telling me it is eplida

 

check out them numbers :  https://www.techpowe...z/details/n8xmv

 

the gpu is pretty much maxed, but the vram hasn't had any issue despite jumping ion increments of 50 - 100 to here, and i sorta just stopped because i doubt more bandwidth will actually add benefit at this stupidly big number

 

 

i'm impressed... all this is at stock volts for the card, as i haven't managed to understand the possibility of using the guru software to add 8% volts "safely" to the card

 

feel free to admire my e-peen; is there any great joy to be had in making vram even faster ? i know more on the core is good, but currently it boosts in gaming to measure just shy of 1400 ! and it does 1401 according to ungine heaven benchmark...  beast !!

maybe ms 22 has been sending me too many articles from the onion, but this sprang to mind earlier today :

power to the people, er.... 'puter

my corsair hx650 recently developed a loud whine in the fan, and though it eventually settled to a disconcerting hum, i had by then applied for rma - accepted - a mere month before the 7 year warranty expired

 

good timing, fan !

 

in retrospect, i discovered the fan had been humming for ages, and i kept thinking one of the many other fans in my rig was the culprit, but was too lazy to trouble shoot to locate it, although one fan in an earlier windforce cooled video card had also been a nuisance

 

 

so, they sent me a silent hx750i - awesome ! apart from the $80+ it cost to return the lump of a 650

 

 

the point of my thread is this : i now have 750 watts of grunt at my disposal in a platinum certified psu, that is so quiet that unless gaming with fans turned up on the rest of my rig, is less noisy than the qnap server parked above it (bloody 40mm fan is crap)

 

idling away with the i5 2500k it uses well under 100w at ~mid 80% efficiency

but even fired up at 4.2ghz on all cores with a gtx760oc plus 2x120 + 2x140 fans turned up for gaming, it is pushing it to need anywhere near 400w; and as the next "upgrade might be a gtx970 or 1060, which would use essentially the same or even less power, i got to thinking

 

the hx750i is the lowest powered high end psu corsair supply these days

 

given the power requirements of both cpu and gpu diminish with each refresh of process size, and ram gets more frugal too, why is the available power going up ?

 

yes, i know that sli and crossfire for monster video for 4k or multi-screen would use it, but for all the rest of us at 1440p or less, meh !

 

what about the average mid to mod-high end casual gamer that mostly surfs the net and does online stuff that a phone could handle ?  surely 500w is the sweet spot ?

 

shit, even for the htpc i recently thought the psu had gone to god (it was the power board i eventually discovered), there was nothing of acceptable quality under 600w for a machine that has as its most hungry component a xonar hdav1.3 sound card (at 40w), which is perfectly capable with an i3-2100 and overkill 8gig of ram and onboard video

 

 

 

tldr : why can't anyone supply low wattage power supplies of high efficiency

 

marketing hype has yum cha 1000w as more desirable than appropriate 350w gold plus

weird nexus connection failure

21 December 2016 - 10:56 PM

i have a nexus 7 (first gen) that is rooted and running 6.0.1 quite happily

 

except - it won't connect to the ubiquiti wireless, but it will connect to the billion wireless

 

 

that is itself is annoying, but more perplexing is that there is another identical model and firmware that connects to either wireless happily - let's call that one "good"

 

my presumption is the ubiquiti has mysteriously got the shits with the "bad" one, but i can't for the life of me figure what the spell that has been cast might be

 

the "bad" nexus will report "saved" and sometimes reports "network connection failure", but i'm stumped - from memory even a re-flash didn't get it to co-operate

 

 

any clever suggestions ?
