post #7101 of 16490
Does anybody know where to measure the core voltage (with a multimeter) for real voltage levels? On the back of the PCB of course. My tool (Gainward) has an option to bump voltage level by +25mv, so at 1.212v it reads 1.237v. I want to check if that's real or not (probably not).

Anyone tried that before? My card is not reference, but almost similar to Palit Jetstream.

This is for ref but when I tested my ref at 1.21 under load it would go up to 1.23. You would solder on to where it says nvdd monitoring looking at the pic the positive goes on the right negative on the left

i'm having a bit of confusion here... i just started ocing my evga 780 ti sc reference. i can hit 1280 stable w/ gpu boost 2.0 but my voltage keeps lowering itself. im using evga precision and i set the voltage up +75 mv but it doesn't go past 1.16v. it hits 1.21v sometimes but it will stay at 1.16 most of the time and will downclock a tad bit. sometimes it will reduce voltage even more to 1.12 and downclock a tad bit more. will flashing my bios help? im just a bit confused as to why this would happen i thought they were supposed to run at 1.2v on full load. my overclock is going to be used for gaming mostly anyways. did i get a crappy card? or should i just flash the bios to make stop downvolting?

problem can't be my temps because it NEVER hits 70C.

Nothing wrong with the card whatsoever. In fact, if it does 1280 stable, it's a higher than average example.

When running the stock bios, you don't "set" voltage. You tell the card what it is allowed to use and the card decides from there. Sometimes when overclocking the card decides to take less power from the power cables and instead take more through the pci-e slot to help stabilize clocks. The downclocking is occuring because of either temperature or power limits being reached.

If you want to set the voltage and have zero throttling, you needs Skyn3t's bios with gpu boost removed which puts control back in your hands.

thank you so much for that explaination! if i do flash my bios and get rid of gpu boost... does that mean my card will not downclock on idle anymore as well?

No, it downclocks and idles just like the stock bios does.

FINALLY my kraken g10 bracket came in!!!

hadn't ordered the cooler for it yet, but a corsair h90 and a noctua 92mm pwm fan should be here wednesday. can't wait to see the OC results for this bad boy! (specs are in the 2014 rig below)

really curious to see how comparable it is to the custom water cooling setups. but i'll have about 1/3 the $ into it since i'm using AIO water cooling.

i know i've heard the vrms get a little warm on these g10's so i may look into the stick on heat sinks for them if i have problems. going to route some of the sabertooth temp props as best i can to the vrm and back of the card and monitor some temps.

Hey quick question does flashing the bios on MSI cards void the warranty...was just wondering? I figured it did and this card doesn't have dual bios so I flashed back to stock bios and I can get within 5% of my other OC so not

Hi, i think it doesn't but have it custom cooling set does, Is yours custom as well? I have mine on stock the twin frozr seems to do an ok job under load i get like 67-69 degrees with high gfx demanding games like crysis 3... I'd really like to WC these guys just to ensure i can extend its life span and overclock it to its maximum potential without risking any harm done to it.. Do you have any suggestions on what sort of cooling setup i need to get for these particular cards?

Hi there, i was wondering if flashing the bios to the skyn3t one would be beneficial in ways of updates, patches etc.. Do they update regularly?
