You have to sand Liquid Pro off of the heatsink, it doesn't come off easily. It's much more permanent than liquid ultra. I have been investigating both of them and liquid pro sounds like a huge hassle. Sent from my HTC One_M8 using Tapatalk

337.88 is working fine on the clean install but they were a mess before. I have not had a freeze in any OS - Windows 7, Windows 8.1, or Linux since I reset optimized defaults in the BIOS, trashed my SSD RAID, and did a fresh install. Sent from my HTC One_M8 using Tapatalk

Just have to wait for Maxwell and Tonga to find out unfortunately Sent from my HTC One_M8 using Tapatalk

AMD chips die far more frequently than nVidia chips. I understand your frustration but moving to AMD will frustrate you even more. I made the same choice when I went from an 8800GTS to a Radeon 5830... Yeah I went back to nVidia immediately. The 5830 was totally unstable. I see failure reports for 7970/8970/290X around but it's rare to see a failed nVidia chip after Fermi. Sent from my HTC One_M8 using Tapatalk

I wouldn't count on it... NVidia doesn't even care to fix it's flagship 880M, they probably will not do anything about the 680M since it's end of life Sent from my HTC One_M8 using Tapatalk

Hopefully they fix it soon for you! Sent from my HTC One_M8 using Tapatalk

337.88 doesn't work? I had issues with all of them except 337.88 so I just did fresh install of Windows yesterday and only put 337.88 and my freezing hasn't happened again (yet) I am using the stock 880M vbios though. Temps are too high for me with the mod unfortunately. Sent from my HTC One_M8 using Tapatalk

Is it overheating? That would be the first thing I would check. Sent from my HTC One_M8 using Tapatalk

I am wondering if anyone is successfully running OS X Mavericks without an xpcm-free kernel? I looked up HM87 and it supports VT-x/VT-d - does Clevo not support both? I did a search and saw xpcm-free is only needed with busted VT-d but I have VT-d turned on in the BIOS along with regular virtualization so I don't know why it has the issue (reboots immediately when the apple logo comes up if I don't use the xpcm-free command and the patched kernel to support it). It's not a huge deal because I know how to use Mac Drive and TransMac to backup and replace Mach_kernel but it's driving me crazy that maybe I'm missing a setting or VT-d option is busted in the BIOS so I thought I would ask.

Same command. The only time you need to worry about using any other command is if the system has an on board nVidia card (old school M17xR1 for example) or cards that have two GPU cores and have a PLX as a result. The default command flashes all nVidia cards found, one or more.

Yeah I slapped it together pretty quickly but my reasoning for finding the stable overclock together is because of those cases where you actually take a performance hit from overclocking the memory as opposed to increasing the core. I guess for the sake of being simple, doing them together works best (and that's what I usually do, I am impatient though).

Dump AfterBurner for nVidia Inspector as a first move, then increase core in small increments until it crashes or freezes, then back that off by about 10-15MHz and you have your core clock. Do the same thing with the memory but I would knock 25-50MHz off your max overclock that you achieve on the memory. While a core overclock is unlikely to kill a card, a memory overclock is an entirely different story. If your thermals allow, you can use the voltage sliders to increase voltage to the cards and push them further. Definitely use something like HWMonitor or HWINFO64 to track your temperatures. Whatever you do to the primary card, choose the second card in the dropdown box and apply the same settings. Once you find a stable overclock that you're happy with, save the Inspector profile to your desktop and you can apply it any time you want from that shortcut. AfterBurner and Precision X have random issues on systems while nVidia Inspector is generally quite stable, hence my recommendation to use that instead. Every card is different, hence why you have to find the overclock on your own. Also when you are testing for your maximum overclock, it is best to set the other back to its base setting (so if you are overclocking the memory, put the core back to stock), find your max overclock for the other then work on finding their maximum stable point together.

Very nice man! I hit a thermal wall with my 9377 at the same point http://www.3dmark.com/fs/2327316 Trying to run 3DMark 11 next blew my adapter lmao The overall is lower than it would have been had I not disabled the turbo and locked the CPU at 3.1GHz. I knew it would overload the adapter if I had the turbo on.

Yeah, its definitely a heatsink defect but ICD works around it with an extra dab at that one corner. Makes me miss my Alienware since gravity works against the video cards in this machine while the M17x had the heatsink sitting on top of the video card. I'm betting that the heatpipes are part of the problem because the back end of the heatpipe assembly has no screws to hold it down so it literally relies on the 3 screws for the plate of the GPU mounting assembly and the 4 screws that tighten down the GPU heatsink to hold up the back end... I might look at modding that later on.

People have said that its hard to apply but I find if I push the plunger and let a bead form at the tip of the applicator and then tap that on the die and press the plunger until the blob I want is on there, it sticks to the die and then I just have to carefully tie up the string that it trails off with. Its certainly not MX-4 but since the heatsink does the spreading for you through the pressure, its not that difficult to apply. The problem with the MX-4 is that even when the heatsink was tied down to the point I was stripping the screws, when I would remove the heatsink it barely made contact as evidenced by how little was on the heatsink. I'll probably be repasting my CPU though and I'll likely use MX-4 for that as I used ICD the last two times and its just a pain to work with when you don't have a square surface. My last application was a line across the center of the die edge to edge and its still hot so I doubt it spread over the entire die properly.

That's a sick mod. I would do that to mine if I could get a replacement bottom cover for mine with no questions asked from xotic which may be easier said than done so let me know how you fare with it. Hard mods like that make me nervous to say the least when dealing with warranty issues. You would think they would applaud enhanced cooling but it just doesn't work that way. It would be nice to be able to run my 880s at 993 without seeing 93C though, especially the secondary since the primary stays around 89 to 90 under the same load. Well about 10 different tries with Mx-4 all ended up with higher temps by 2-4C than ICD so I gave up on it. Still have a bunch though (was like a 20g tube lol)

Yeah I know that some are like that, I was just offering an alternative to trying to solder the card. Even for me, soldering would be a last resort after I tried literally everything else. I know that sometimes that is necessary in the end but I also wanted to emphasize not reporting anything to Dell. All it takes is for them to send out a tech with a brain and the entire system is void, not just the graphics card. Here in CO, they have some contracts with techs that actually are quite good.

The other option is to find someone who has a system with onboard graphics and stick the card in there, have them boot from onboard, then flash the card with stock. If it finished successfully, its quite unlikely that it's bricked, it just needs to be reflashed with the stock image in a system that has onboard. I flashed a bad vbios to my cards in my Clevo and had to stick one in my old M17xR1 and boot off the integrated and flash the card then put that back in my Sager and flash the other. 120hz display means no onboard graphics. I wouldn't call Dell, they will void the entire system warranty if they find out. If that card is alive and the tech sticks it in a machine and sees the modified bios, you are screwed.

Stock out of the box it will have a performance improvement because it stops your GPU from needlessly throttling. It is definitely useful to everyone, not just hardcore overclockers Sent from my HTC One_M8 using Tapatalk

I wonder how much more that benchmark is boosted by your superior RAM and vastly superior CPU. I can't get my RAM to 1500 so I tested it at 450 and boosted the core by 20 to try to offset it but no dice Catzilla incoming if my system will pass with it, hopefully it doesn't overload my 330W adapter at these clocks lol. - - - Updated - - - Catzilla 1080p (note the 93C, it started to throttle at the Raymarch and fluid tests slightly but its still the best score I've gotten on Catzilla to date)

DOH! I don't know how I missed that, I looked for it the other day! Thanks Prema

Anyone know the cheapest place to get one of these? I've been seeing 70 + shipping which is ridiculous in my opinion for something that should have been included when purchasing a spare PSU with a 9377. It is really easy to trip the overload protection (I've done it on both adapters) when you start tweaking either the CPU or the GPUs but when I've already dropped almost 5k on my machine, it kind of sucks having to spend even more money to put my 4940MX chip or my 880Ms to work, let alone tweaking both.

Is there a stock Sager NP9377 BIOS + EC around? Or even a P377SM-A Clevo BIOS + EC? I can find stock for all but my model and I might be RMAing this machine so I'd like to put the stock Sager BIOS back.

What make and model do you have? I know that DOS will work in UEFI mode if you use the right tool but I don't want to recommend that until we get confirmation from someone that it functions the same as BIOS mode and won't brick your cards. Firestrike @ 1128/2800/1.087/130% Unforunately its not able to pass 3DMark 11 and pushing them to +100mV is too much for my 330W adapter and causes the overload protection to kick in. It didn't even drop me to battery, it straight shut the computer off lmao. Still, that's pretty impressive. Max fans of course but 82C on the secondary GPU says there is still more room, at least for benching, I just need a Clevo converter box.

You have to disable UEFI booting when you flash the cards and then turn it back on. Sent from my HTC One_M8 using Tapatalk
