I'm kinda new to overclocking here, and I'm wondering the consequences of overclocking my HD6950. I already have the additional shaders unlocked, and I would like to bump the clokcs and voltage up to 6970 levels. Will this damage my card in the long term? Its a Sapphire, so it is at least a good card.

grumperfish posted:It's fairly easy, especially if you're already unlocked. 880/1325 or 880/1350 on my card (XFX) only needed a small voltage bump to 1.1V which didn't add much heat with the reference cooler (using 950/1350 @ 1.2V now with better cooling though). Oh ok, thanks. I already had the clocks and voltages saved as a profile in Sapphire Trixx though. Would you recommend using Afterburner over Trixx? Also, I just want to be clear on this, as long as I keep everything in check, temps and voltage, this won't hurt my card permanently?

I played with Trixx, and I have my 6950 running stable at 880/1325/1.14v. It runs Battlefield fine, temps stay under 60 and no hiccups. When I run Uningine Heaven though, sometimes (uncommonly) I get screen flashes during the benchmark. Settings for that are everything at highest except no AA. Is this bad?

grumperfish posted:Screen flashes are a little unusual but it doesn't sound like GPU artifacts. It's probably not anything to worry about if the card's working fine in games. It flashed when I ran without any overclocking, but it was a little rarer. It wasn't doing it a lot, just like once every just maybe 5 or so times in the entire benchmark (with OC).

FormerFatty posted:I had flashes every 30 minutes or so which eventually turned out to be caused by my cheap HDMI cable. If you have this problem, don't waste your money on an expensive cable, just buy another $5 HDMI cable from somewhere else and you should be fine. I'm not using HDMI, it's actually a VGA monitor. Think that's the case then? e: Regardless, I'm not worried about it, everything seems stable and running fine, so thanks to everyone's help.

Ok, question. What keeps resetting my voltages? every so often I'll look at Trixx, and voltage has reset to 1.1v, but the clocks stay 880/1325. I just reload the profile and it stays that way. Could Catalyst be affecting this?

grumperfish posted:I noticed something similar when I was using Afterburner with the CCC loaded (before I reloaded the non-CCC drivers), where the GPU voltage was dropping back to 1.1V randomly. Actually, I don't know, that was the voltage some people mentioned a while back when I unlocked the shaders. I'll see if it does stay stable on 1.1. Edit: Apparently no, it won't. 1.11v seems fine so far. Bumped everything up to 900/1350 as well. Endymion FRS MK1 fucked around with this message at 22:38 on Apr 13, 2012 |

Small question about a really modest overclock, 4.2ghz on an i5-3570K. I have an Asrock Extreme4 Z77, and don't know if I should be using the Turbo 4.2ghz setting or straight up changing the multiplier to 42. Also, how do I lock the voltage at stock? Both of those options raise it automatically to 1.275 instead of the normal 1.2.

Factory Factory posted:You can't overclock without using Turbo. If it shows you that happening, it's just an abstraction for your benefit. You do want to overclock without the per-core frequencies, however. For the turbo, it was an OC option called "Load Optimized Turbo", and it auto-set the multiplier at 42. I have no idea what it changes aside from setting all cores multiplier to 42

Ok, thanks guys. Now I just need to hunt around the settings and limit the voltage, unless you think 1.275 would be safe for a 24/7 overclock? You said under 1.3 should be good, and I have power saving on so it downclocks to 1.6 when I'm not doing anything intensive.

I was doing some experimenting last night on an i5-3570K and ASRock Extreme4, ended up after a 12 hours Prime 92 Large FFT test with one core erroring after 17 minutes, was at 4.2 with voltage offset to be at stock, LLC at level 3. What I noticed was that my BLCK was at 100.5. I reset everything to stock, and BLCK is still at 100.5, despite being set to 100 in the bios. What is going on here? Is it even a problem? Edit: What is the voltage limit for IVB anyways? I'd like to do 4.4-ish increasing as little voltage as possible. Endymion FRS MK1 fucked around with this message at 18:13 on May 31, 2012 |

Beautiful Ninja posted:So I just got an Asrock Z77 Extreme4 motherboard, paired with a Core i5 3750k with a Coolermaster 212 Evo installed. Is there any reason not to use the overclocking software that Asrock included instead of doing things through the BIOS, in terms of stability or whatnot? The last time I had a PC where overclocking was worthwhile was back in the days of Mobile Bartons. I have the exact same setup. Just go into the bios, set the multiplier to 4.3, voltage offset to +0.05 or +0.10 (don't remember where mine is), you'll be good.

Beautiful Ninja posted:Yeah, I think I figured out what my problem was, I had too much thermal paste on, cleaned it and put on a smaller amount, hopefully that fixes things. I can't remember what my IBT temps were (I want to say high 70's low 80's like you), but it runs mid-high 60's on BF3 and similar games for reference.

I was messing around with a CPU overclock the other night, and ended up making my system unbootable (into Windows, it was able to POST just fine). I repaired the boot files with a Windows 7 CD, but did I permanently mess anything up? Also, why does it seem like my motherboard is giving too much voltage? Offset +0.005 gives it 1.275 at load on a 4.3GHz OC on a i5-3570K and ASRock Extreme4 Z77

No, using the repair fixed it, I was just wondering if anything like my files or program were corrputed. Also, every voltage monitoring I used read 1.264v @ 4.4GHZ and -0.005 offset this time.

Alright, so apparently my new Gigabyte 7950 is voltage locked. Is that a bios thing where switching to the alternate one via a switch solves it, or is it hardware locked? It's not a huge deal, I can still play BF3 at 1100/1400 and sometimes Sleeping Dogs (it seems a tiny bit crash happy with any overclock, haven't actually tried it with stock clocks much though), just wanted to see how much I could do with a tiny voltage bump. Even more interesting being that the card runs at 1.09v instead of what I assume is the normal 1.1v.

craig588 posted:Give the Vcore another .005, you're not near any sort of warning zone for IVB voltage yet. Instability can make you second guess everything if you ever encounter a problem with anything in the future. (Was it my overclocking? Did I leave too many tabs open? Do I need to update my drivers? Is is a legitimate bug? etc) What is the warning voltage for Ivy anyways? I've been at 4.3 @ 1.24 since it launched.

I finally got my NH-U12S today to replace my clicking Hyper 212+, and  holy hell this thing is quiet. I'm used to my Hyper 212+ being stuck on full (some weird bug with Extreme4 Z77s I guess?), and with this cooler, variable fan speeds are actually possible. Also shaved a few degrees of my IBT temps, ran 4.4 @ 1.255 (normally I'm at 4.3 @ 1.230) at low-mid 80s instead of low 90's, and much, much quieter.And now I'm annoyed at how loud HDDs are

Finally got a NH-D14 to replace my Hyper 212+. Doesn't come with PWM fans though  I'm pretty impressed. Ran my i5-3570K (that is a horrible OC-er) through 10 runs of IBT at 4.4ghz and 1.31v, only cracked 100C a couple times. Even a 12 hour Prime95 run ran high 80's, this time with the ULN adapter. Hopefully they release a mounting system for whatever socket Skylake uses, would love to keep this thing when I upgrade.

HalloKitty posted:They will. Noctua are pretty good about supporting their gear. Awesome. I was thinking about replacing the fans eventually. Any good PWM fans cheaper (and preferably quieter) than Noctua's F12 and whatever the 140mm equivalent is? Factory Factory posted:Ehhh. That does help, don't get me wrong, and most people don't actually do the "100% load 24 hours a day" type loading that a 24/7 overclock is geared to, but you are around the range where if you need to keep using the chip 4-5 years down the line, you suddenly might not be able to. Three years if you're unlucky, and with a chip that doesn't clock well to begin with, you may well be unlucky. Hmm. Might back down to the old 4.3 @ 1.24 I had going. I keep hitting that voltage wall once I try to go above it.

Still not sure if its a code bottleneck or CPU bottleneck or something else. Well, did the save again with my 7950 and i5 again, got a time of 12 seconds. Both GPU-Z and HWiNFO64 showed 0% GPU load, and clocked at 300/150 (idle clocks). Ran again, got 11 seconds with full clocks and 28% load. I'm confused.

Not prior to this test (I assume switching off GPU optimization resets it?), but it was run before the one you included in the chart. Went ahead and ran again, same results. Hovered between 25-28%, time was 11 seconds. Edit: Oh wait, that's 2 seconds faster? All I'm doing is saving that drat stock photo, I don't want to potentially screw up your results

LCD Deathpanel posted:I've seen something similar happen in HWiNFO, where the fields for my videocard (6970) will occasionally report impossible voltage minimums and maxes coming out of standby (like, voltages that would fry the VRM chips immediately if they were actually happening, and not a sensor read malfunction). Yeah HWiNFO seems glitchy sometimes. The past nearly a year I've lived with a 7950 pulling around 20000-30000W after a bios flash. Sometimes it fixes itself, sometimes it shows those values.

Quick question. I have a GTX780 and a locked i5 running on a 450W supply (not some no name one, don't remember the name off hand just trust me). I haven't tried overclocking the 780, what are my limits? Or should I just not try anything. I'm so used to my old 7950 and a 650W where I could do anything.

I have a question. I have one of those Steam Machine beta units, and eventually (Skylake-ish?) I'll need to upgrade the processor. My question is how I can do any sort of good cooling or water cooling. I've never worked in anything this small or with water. Here's what I'm working with:

Which small motherboard would be best power-wise for a 5ghz 8086K? I'm leaning towards the Asrock Z370 mITX Fatal1ty and the EVGA Z370 mATX. It'll be going into a Meshify Mini C case, so mATX is the biggest I can go.

All EVGA Z370 seem to lack it? Edit: Guess my other choices are the MSI Z370 Gaming Pro AC or an Asus Strix Z370-G, but I'd maybe be better off with the EVGA Edit 2: The CPU itself will be delidded and cooled by a Scythe Mugen Rev B Endymion FRS MK1 fucked around with this message at 01:59 on Aug 14, 2018 |

The Strix Z370-G is overpriced for what you get and I don't have a great deal of faith in MSI's BIOSes (I'm assuming you meant the MSI Z370 Gaming Pro AC). Oops yeah, meant the MSI one.

Thanks, that's what I've been coming up with too. I did find a guide from der8auer saying Prime95 with 1344 min and max should be used. So far I can only pass it at 5.0ghz and 1.32v. I think I got a bad 8086K Sidenote, not really a fan of ASRock's settings. I'm using offset voltage at -140 (I think, might be -150) which actually increases voltage to what I want? That plus LLC in the middle gives me roughly 1.32v Another sidenote, I should be ignoring VID in hwinfo right? Anytime I use offset it gives me like between 1.4 and 1.5v, but vcore is giving me the right voltage, as in CPUZ also gives me the correct 1.32v core
