Only planning a slight OC on each card as don't need to go crazy with sli but might pump up voltage and OC for some benching so I'll report back if I have issues.

According to link below I should be OK.

Thanks for posting the link and since you aren't looking to push things too much you can get a basic idea. Be careful about those posted values though, they are not testing the same way we do here, actually not even close.

Just to keep apples/apples for those following the bouncing dot, I took a look at the link and just want to clarify that these results are "typical/average" and even "real world" results but not MAX Power draw potential. I don't think they are even overclocking. The max value that they record is a max value under gaming and synthetic tests, that typically don't max out your power draw. In addition the values are recorded using a STOCK BIOS which in terms of power makes a considerable difference.

It says "Furmark" test but how were they testing??

For example, they have a G1 980 only showing 196Watt MAX and we know that with a MOD BIOS, overclocking both GPU and MEMORY, and an extreme test with the right settings, we can almost DOUBLE that max value.

I think that we would need to measure power draw from a range of games, tests, benchmarks, applications and mining to know EXACTLY what "Real world" power draw scenarios could possibly be, and that's too much time, work and money to acquire all that software and perform the testing.

To be clear, I know some of you are concerned about your power supply not being sufficient, AND YOU SHOULD BE, however please keep in mind that there are 2 very popular ways to look at a power supply requirement:

(1) How much do I really NEED "on average/typical/real word"
(2) How much do I really NEED "at MAX possible power draw"


Running your PS at 80% efficiency under max load is different from running 80% efficiency under "typical/average" load.

I always go overkill like cookieboyeli and many others so I'm more of an OPTION #2 kind of guy. Many other are OPTION #1 kind of people and that's perfectly fine.

PRO/CON to OPTION #1 - Save money up front, MAYBE you'll be just fine with NO issues but won't know 100%, there's always a shadow of doubt.. Future upgrades are uncertain.

PRO/CON to OPTION #2 - Spend more money up front, peace of mind that your PS is MORE THAN ENOUGH in all cases, Future upgrades are essentially covered.


I think we should run some additional tests to measure power draw with this MOD BIOS during the same "on average/typical/real word" and get some of those values recorded as well. More to come smile.gif

Any values we are going to find on a "reviewer website" is going to be STOCK BIOS values (and probably not even overclocked).

Does anyone know when it's likely to be released?

I'm happy running my card with mild OC (or even stock!) for time being and using a custom curve to keep the noise down.

But still can't beat being under water (especially when the rest of my system is!)

I asked in the EK thread and the birdie there said at LEAST 1 month to wait..

If I have some free time I might be able to dig out my multimeter and do some testing, I'm very curious as well.

Check this out:

Keep in mind, ALL of these videos are using stock BIOS and not overclocking GPU or using MOD BIOS but I respect these guys (and in the process found a LOT of BAD power supply info from others).

To be clear I am not getting any kickbacks I could care less if you buy Corsair or not TBH but this is what I have.

Laithan, thank you so much for taking the time to write that! I had been somewhat frustrated seeing so many take the "wrong option" cutting corners with PSU's and using lower voltage for power savings at the expense of lower clocks and temps, but now I see it is really a difference of opinion, not objective wrongness. biggrin.gif
My overclocking soul can rest in peace for a while longer. tongue.gif

Glad I got the OCZ ZX 1250W a while back. I been using this thing for 5 years now. Also when you have a higher power PSU it will last longer since its components will not be used on its limits.

Thanks for the heads up.

Looks like a BETA BIOS though, never seen them post a BETA BIOS there before.

Hi Laithan, I'm getting a G1 980Ti soon should I flash the beta v2 bios or wait for an upcoming version?

It's worth a try. I'd suggest finding your max OC on stock first to see what it's capable of. Then you can determine how much his bios improves your performance

As of this time we have identified that V2BETA can result in PWR perfcaps in certain tests so we are scheduled to increase the power a bit for V3BETA. Outside of that change we are still waiting for some additional feedback on the custom fan settings and if anyone else has any additional general feedback. V2BETA just needs some final tweaks but overall seems quite stable so no reason to wait if you want to overclock now. My cards should be in Thursday according to the UPS man so I will be installing them probably this weekend. I will of course be testing with the STOCK BIOS as well and then flash V2BETA right after that to "see things for myself" tongue.gif

Bottom line is that if you are getting your card in the next day or so, you can flash V2BETA and then maybe a week or so later I should be posting V3BETA with just a slight power increase at this point.
