~~The GTX 670 Overclocking Master-Guide~~ - Page 258

post #2571 of 3357
Hello I cant seem to overclock at all. The test runs well on stock with no problem. Once i start the first test with gpu clock offsets +120, the unigine 3.0 goes black screen but music still in background. When pressed Esc, it quits the program with an error. A long listed one. After this error, i cant seem to do anymore tests including everything @ stock. I also did turned off Precision-X and back on again. The only workaround to this is to restart my pc. Again, stock is fine anything more is not. Im beginning to suspect its my mobo because the vcore on this one is not adjustable. Does it have anything to do with that? My pc specs are:

Gigabyte Z77m-d3h
I5 3570k @ 4.3ghz (stock voltage)
Thermaltake Water2.0 Performer
Asus Gtx 670 non-TOP
Seasonic 620w

Does anyone have an answer to my problem? Its driving me nuts. Thank you in advance. Sorry for the long post frown.gif

I'm out of my depth. With the win7 reinstall and a clean 314.22 driver install on top of that, I think you can rule out any sw config/install issue. I don't know much about BIOS mods and the tools that produce them except that they exists. I don't know where those drivers on the techpowerup site come from. If you've got an up to date BIOS from your cards vendor on the card now, that's the most kosher setup you could possibly have. If that setup doesn't function properly, i start to question the hardware?

When valley crashes, how does it crash? Is it a TDR error indicative of the GPU having crashed or is it a valley x86 code crash? I've been assuming its a GPU crash and not a windows program crash. If it's the win program thats crashing, I might wonder about a cpu or system mem overclock stability.

If you underclock the GPU, does that make a difference? If so, seems like that would point in the direction of a hardware problem (not being stable at stock clocks).
It's the actual program that crashes itself. I haven't tested my RAM in a while.. maybe it's a good idea to check it now. Should I test them how they are right now in dual config or test them one by one?

It might not make any difference at all but give the 326.01 drivers a try like I suggested on the last page. It made all the difference for me. 320.xx series drivers are junk; The 314.xx series are definitely better, but I've still had the best luck/performance with 326.01.

Nvidia 326.01WHQL

Like I said it might not have anything to do with the drivers, but it's worth a shot, and yes they work great with Windows 7, even though it says for Windows 8.1 preview. smile.gif

When you say "Vcore on this one" do you mean the GPU? The Vcore on the 600 series cards are locked unless you edit the BIOS to change your Vcore values and flash the BIOS.

Kepler BIOS Tweaker v1.25

And one less thing to try and I don't think this will do anything, but might as well try. Bump your Vcore on your CPU up by 0.01v, just to make sure the CPU isn't becoming unstable because of the extra power draw from the GPU overclocked.

Come to think of it your PS is 620W and depending on it's certification it could become wonky with an OCed 3570k and a 670 at full tilt. I have an 850w PS, you might be getting close to your PS draw limit.

Dude thank you for your reply. Tried the driver, still same problem. Its the motherboard i think. "Vcore on this one" is refering to the motherboard. In the bios itself it does not have the feature to adjust the vcore. Hence im stuck with stock voltage when oc'ing the i5 3570k.

So my question is does this issue have any effect on the oc'ing of my gpu? I cant control voltage of my mobo, So does it mean no matter what power target and voltage i set on precision-x it wont take any effect since the mobo is stuck with stock voltage?

If you look in "Control Panel\System and Security\Action Center\Check For Solutions", do the errors show up in there as "Video hardware error". If so, then i wouldn't think its a cpu/mem stability problem. Random other thought provoked by cody's post, your rig info doesn't list your PSU, any chance your system is giving whatever you've got too much of a workout?

Will try that later as soon as Memtest finishes, thanks. And I have a SeaSonic M12II 620W, so I think I'm fine. What I'm going to do is borrow my friends 660 Ti and put it in my rig and see what I get.

The Vcore setting on your mobo would only control the Vcore to the CPU. The 600 series cards are lock at 1.175v max in the default VBIOS. Yes, you can overclock them; I'm folding at 1280Mhz & 4316Mhz Ram and I can still push it farther, but it just depends on the silicon lottery.

It shouldn't crash like that if you can't overclock it at all. Make sure the Power Target slider in Precision-X is maxed out at 100%+, whatever it will go to, mines goes to %132, but depending on the card manufacturer it will vary. It sounds like your PSU might be the issue. Even if your not pulling all 620 watts, power supplies also have different ratings/certifications, even if two different power supplies are rated at 620 watts one might be able to sustain 80%, 90% whatever of the 620 watts no problem and the other one might start to freak out when you approach 80% sustained. (This is just an example).

So regardless, at somepoint I would upgrade to an 850 watt power that is bronze, silver, or gold certified...I think that's still how they are rated/grouped.

Hey I just reread your post and you said you started with a GPU offset of +120...you might not be able to get +120 out of it. Start out at +50 first and see if it crashes. I need to pay more attention lol, my offset is +140 @ 1280Mhz, but some people can't get over +100, so start small at +50 and work your way up; Also your offset will be different than mine because the offset is based off the boost speed and each card is a bit different.

Are you having precision-x use a software fan profile? Are your GPU temps under 70C because the card will throttle itself a bit over 70C, then a bit more over 80C.

Just got an update on Memtest. I didn't believe it, but 4 hours in and an error showed up.

I guess that means RMA time for the RAM? Is there any point in continuing the test or just cancel it and start disassembling my PC?
post #2580 of 3357
Any chance you have the capabilities to measure your Vcore to your CPU and/or the Vcore to your GPU with a digital multimeter? Software monitors are almost always not what it actually is and I just keep wondering if your getting some kind excessive voltage drops under load.
