780 Classified Overclocking

I could not get to 7ghz memory on my card either. Crashes pretty quick on anything close to that.

My memory is also Hynix. I should just throw this 780 in the garbage and run away for ever! :D
 
I seem to have a lot of vdroop going on. When I run at 1.275v it drops to around 1.23 - 1.24ish while benching or gaming.

I heard there is a way of disabling it, but not sure how. Any ideas?
 
Just a little update.

I did not like how my 780 was behaving and decided to replace it while I had the time.

Just received the new one and so far seems to be much better. At 1.21v I was able to complete a heaven run at 1306mhz on the core. While only seeing 1 blue line flicker at the very end.

Much better considering my old one crashed at 1.3ghz even with 1.325v set at the very beginning of the bench.

Will play around some more and see where I top out at. :D

Well I ended up going with the 780 Classy over the 290x anyway.

I sold my 780 Classified and bought an MSI 290x gaming (My plan was to crossfire for 4k) I wish I hadn't.

With both at stock clocks I found the 290x slightly ahead but once I overclocked both the 780 would be ahead. The 290x is also HOT, 20 degrees hotter in fact and that's with no manual overclock, I did major fan changes to accommodate it in my build but it still hit's 94 degrees under gaming load (compared to the Classifieds 74 degrees in the same system) but now I've got two 14cm side fans blowing air out and warming the room (ready for winter :( ). Hopefully I'll of sold it before then though.

Anyway I think you made the right choice so well done.

Well I don't know if I did lol. This will be my second 780 Classy. I had just received this replacement yesterday and today it made a pop and now seems to be dead.

If it was not a replacement only policy I would get my money back and walk away from all this for a while.
 
I never went over 1.2 when overvolting although I did it with the Classified controller program rather than the evga tool, I did go to 1.25 to do a couple of benchmarks once. I found it to be a great card my favourite to date.
 
Yeah this last one I had seemed fantastic. Was very pleased with how well it was running. Seemed to be game stable at 1300/1752 at 1.25v. Was doing a few bench runs at 1320/1802 1.27v without issue.

When it popped it was at stock clocks with stock voltage on desktop. Popped when I hit apply on the Classy tool for 1.25v.
 
Guys, how is it you find the ASIC rating again. I own two gigabyte wf cards. They have such a good cooler, good uk based rma. I just wish gigabyte would make a card that clocks like an msi lightning or an evga classy. The latter seems like the perfect card, but then you gotta factor in evga's dodgy warranty.
 
Open GPU-Z and right click the top part of the window and select 'Read ASIC Quality'.

My last Classy was definitely an awesome clocker. A real shame she popped on me.

My replacement will probably be a dud again.
 
Cheers Rroff. Both read at 74%. One is a rev1 wf, new one is a rev2. Im very impressed with them at stock in sli. Not so to oc with. First card is only able to do +100/300. Second one does +90/500. So far ive only benched both at +90/300 albeit with a stock cpu and ram. Maybe go easy on this cpu as i might get shot of it soon. Haswell has been very dissapointing tbh.
 
81.4% on my WF 1110 out of the box iirc max boost,, 1267 with a skynet bios and 1.212 i think (whatever afterburners non modded max is), i have gotten over 1300 stable on heaven with the pulled precision software and 1.3v, But it did have horrible coil whine for a day or so after so be awhile before i retry that
 
1300 is very nice triss, my best card maxes at 1200 on stock bios/volts. Thats my new rev2, (x2 8 pin pcie). Ive benched the cards but not with the cpu oc'd. My psu is quite old and im wary of putting a high cpu and cache/uncore and ram clock on this system. The cpu should be good for 4.8ghz 24/7 on 1.3200 ono, 1.25 on cache at 45x. Its just getting the time to test. I cant run normal stress testing such as prime or ibt as haswell chips arent designed for such high temps.
 
Yeah mines a rev 2 , But has the A1 core, but is really a ok clocker for what i do atm, will look at sli and watercooling next year or new cards really going to depend if new games come out requiring more than 3gb for 1440p ,if they dont sli and water will be my best option i think, I do regret not buying a classy Bit it was a 1/3 more again in price for what i paid so cant complain
 
Predominately a gamer here, (stock speed on gpu's). But i do like to bench a bit on the various charts on here. Never gonna top scoreboards but it's nice to try and get on in the categories similair to the kit i own. I got theese two cards for very good prices on ocuk's members market, (£290.00 and £255.00 respectively). Tbh i cant afford to buy a new high end card when its released, hence i go secondhand so often.
