Best 7870 manufacturer for Overclocking?

post #1 of 20
Thread Starter 
It's time to upgrade from this old, soon dead (showing me bad signs) 4850 to some better stuff: 7870!


But theres many manufacturer opinions, and don't know which one to choose/would be best.


Im going to overclock it to max with Arctic Accelero Xtreme 7970 or Accelero Xtreme PLUS II. So I would not want to pay more from better cooling solution. Which manufacturer would have best OC capability when changing voltages too?

Im also wondering does every manufac. void your warranty if you replace the heatsink?


I read about that AMD 7900 price drop, so Im also considering to get 7950 instead of 7870, depends when its going to drop here in Europe and what the price will be. What do you think, would extra vram be worth of the $? Atleast I think so, because when I bought this 4850, it had 512MB vram, couple years gone and wanted to play GTA IV, it ran pretty nicely but would run more nicely with more vram. So would maybe be better to get little better for future than cry in future biggrin.gif


And yeah, my budget is about 360€ (470 dollars), thats what 7870 costs here.


Thanks for any useful information!

MSI won't void your warranty if you replace the cooler IIRC.

msi, asus and xfx are good companies when it comes to removing coolers and whats not(dont know if saphire is too). But its a waste to get a non-reference cooled card and remove the cooler, but hey it might get you better results. Anyway the main concern is the compatibility of the cooler with such cards. Reference 7870 is definitly supported, but dont know about other models, check the support page of the cooler and you see what options you have, then we can help you select.

I was able to hit 1225 / 1450 on stock voltage. Other 7870 users have said if they go above 1200 it crashes the amd driver. I am currently at 1150 / 1350 stock voltage for everyday use

I haven't touched the voltage but plan on it sometime this week.

Amount of VRAM depends on what resolution and the amount of AA you plan on using.

2 GB is plenty for BF3 on max settings. The only game I have trouble with in this department is Project CARS which is unreleased (2013) still in Alpha stage and anything but optimized at this point.

I read the price drop on the 7950 in NA will be $399 (7800 series receives no drop; 7870 @ $350). I don't know about pricing or dates for Europe. If you have the money you might as well go for the 7950. I always thought the 7950/70 were overpriced and compared to them the 7870 was a bargain especially when overclocked, even on stock voltage, the 7870 will perform better than a stock 7950. The price drop is expected and respectable comparing price to performance within the AMD lineup.

As far as what manufacturer voids the warranty look at pictures and reviews of the cards. If they have stickers on the screws then there's your answer.

Sorry, I just edited this like 5 times.

MSI WILL void your warranty.. I've contacted them with my 6870 (when i had it). - I wanted to re-seat it/put a accelero extreme on it.

I don't know about voiding warranty but if you're over-volting ASUS have the best warranty for this, they also come with half decent coolers.. So reference 7870? If you don't have the cooler already go with a non-reference 7870, maybe a hawk by MSI..?

Because this generation of cards runs considerably cooler then last gen, along with less power usage so less heat on the VRMS if i'm assuming correctly.

Then again, you could always buy a half decent non-reference.. Then buy the cooler after depending on your temps? thumb.gifthumb.gif

No need for an Accelero.

Not the most popular brand but they have been real solid lately

Well yea, they are the same price as reference cooled card except MSI which costs 50€ more. I prefer reference PCB than modded one because of possible manufacturing problems. I think almoust all of those are reference than some haves 2 DVI ports?


@di inferi
Hmm, I would like to know with voltages tongue.gif
Im at 1920x1080 with my screen and sometimes like to play on my 40" TV but it also haves only full HD resolution and I usually like to max out AA. If that price drops that close here too, I think im going with 7950 then smile.gif


@Matt-Matt
I already have both of them, got em free biggrin.gif Just need to decide which one to put on.
I dont have to use them also could sell them but I think if I touch voltages too temps will raise and I need better cooling.
But assuming that reference cards should be cheaper? or why would you suggest them?


Edit:
@Redwoodz
Not even when raising voltages pretty high? Im new with this 28nm process stuff.


To mention too that I like to cool my stuff pretty low if possible tongue.gif
