Gigabyte R9 280x OC (with numbers)

[gylmir]

The title says most of the part.

since we all know gigabyte card are voltage locked so don't suspect alot if it was not locked i could get more out of it but i'm happy with the score i got.

This is also my first gpu overclock.

 

to see the difference i run heaven benchmark with stock settings

 

i first jumped 25 on core and mem until i got my unstable clocks, backed the core back and had the highest stable core clock of 1180Mhz.

then i was going further on the memory until it began to get unstable, again i jumped with 5 up and down till i got my score.

I found 2 stable clocks for the memory but they have some bad points and some good points. i ended up with 1750Mhz and 1775Mhz

the higher settings give higher max and also lower fps so i stick to the 1750 and its a decent oc for me.

 

Core 1180 Memory 1750

 

Core 1180 Memory 1775

 

and since people are willing to know more than just heaven benchmark i did a 3 min run of furmark

 

 

Here is the screenshot from the valley bench i run

 

CONCLUSION

I had a great time overclocking my gpu but every time i bumped the coreclock higher than 1180 or above 1200 it keeps hanging before i start benchmarking.

The highest temps on the gpu i know was around 64° in heaven benchmarks also the furbench was taken right after my last heaven benchmark thats why the start temp is 42°.

The fanspeed was on auto and i noticed that once above 70% the noise is a little higher but the temps stay at the same point this is maybe a great tip,

i also tested a few times on 100% it is doable if you wear headphones otherwise lock it at max 70%.

 

if you have any questions about the overclock feel free to post them and i will respond asap.

Did you get the old Windforce card with the blue PCB or the newer one with black PCB and redesigned Windforce 3X?

Also, really nice numbers you got there.

You should test out Unigine Valley on ExtremeHD preset and post screenshots I'm curious how it compares to my Gigabyte 7950 (GV-R795WF3-3GD) i have stock and OC screenshots

[Recon-UK]

Tiny OC... push it to around 1300mhz with some volt mods.

[gylmir]

@lachyman its the old one with blue pcb

@Luke thx i will test it and post another screenshot

@Recon-UK i would do that but you know it is voltage locked (gigabyte) highest voltage he go is 1.2volts

Is the voltage locked at a hardware level or software level (BIOS)?
If it software level, flash another card's BIOS on it. I mean, the damn card has a BIOS switch on it (two BIOS chips)...might as well use it.

@-Rascal- i asked this question on the forum already but since i don't know from what card i can use the bios if you have any sugestion i will try it because i realy want to have higher clocks on this card

[Dubonfire]

Here some Asus numbers

 

Asus R9 280x DCUII TOP V2 (memory 1500 vs 1600 non v2) 

 

Stock clock  aka 1070-1500  auto fan

 

baby overclock  just to say it's overclock 1100-1525  (+ 30 core + 25 memory ) (fan at 50 % 65 degree C )

i flashed my card with the bios from msi edition it is still voltage locked and the overclocking abilities are not better.

added valley benchmark to the list

 

anybody who knows a bios that is not voltage locked for a R9 280X may always help me out

max gpu voltage for asus is 1.3 volt

I figured what the heck and just benched my Sapphire 280X Vapor X. I'm overclocked at 1170 core/1650 mem. Stock was 1070/1550. Running stock voltage since that is locked on this card.

 

Never really tested it thoroughly, never benched it, just ran it for awhile while somewhat less overclocked than what it is now, and had no issues and it ran really cool, so I bumped it up to where I'm at now awhile back. I have a good month or so of gaming under my belt with these settings without any crashes or artifacts or anything. Never went above 60c during the bench. My fan setting is linear from 50c and up, so for example 50c is 50% fan and 60c is 60% fan. 70c is 70% fan but there aren't any games push it that hard.

Uhm guys... depending on what OC-Tool you .use :::I use MSI AfterBurner and in the settings of that thing you can say something like "unlock voltage control" or something like that. just check out the settings.. took me weeks to figu.re that out

I believe this is considered as thread necroing.
