Which manufacturer for AMD 6870?

post #1 of 6
Thread Starter 
I'd like to know out of Asus, MSI, Biostar, Diamond, XFX, Sapphire, Gigabyte, HIS which is the better and why?

Is one a clear choice over another?

Are they equally as good?

Do some stand out for being worse?

I know this is more of an opinion unless some facts go behind your decision. I have a Biostar and not much reviews on them and looking to possibly return mine and switch for another manufacturer.

Biggest reason for me is when I tried to overclock my Biostar to GPU settings core clock 1000Mhz / memory clock 1250Mhz it freezes Crysis. If I back the GPU settings core clock down to 940Mhz it seems to stabilize. I'm assuming this is due to poor quality in build so trying to get a grasp on companies.

I've read some reviews of other manufacturers having better stability at higher overclocks. Most likely due to better building on their part. Just trying to figure this out while I can return mine and before I buy a second for CrossFire.

Thanks kindly.

Sapphire is good.

MSI is amazing with their cooling Unit. the Twinfrozr II.

Asus is good for RMA and warrenty! same goes for XFX!

imo get the cheapest. in most cases that will be sapphire

Asus, gigabyte, and msi are pretty much on the same awesome level. They give you a 3 year warranty and rma's are very simple because they go off of the serial number, which also means if/when you decide to sell it, the next owner will have a full warranty on the card, no warranty registration or transfer required.

Msi and gigabyte usually make the best non-reference designs, which although I love asus, is very much lacking behind.

Go with whichever is cheapest and fits your needs best among those three companies. All of the other companies are not so cut and dry with the warranties and a lot of the warranties are not transferable, sapphire for example.

EDIT: By the way, I just read your full post, and poor build quality is NOT the reason why your 6870 does not overclock well, it is because some 6870's don't overclock well at all. I have an asus 6870 that on the stock cooler only did 950 on the core.

To be honest, keep your card. There is no reason to send it back just because it doesn't overclock well. You paid for the rated specs, and you got them. Overclocking is never a guarantee, no matter what company you buy from.

Can I run two different AMD 6870's CrossFire? Like a Sapphire or MSI Frozr II with my Biostar? I'm imagining they both have to be set at same core and memory clock speeds?

Sapphire.

If you happen to get (as someone said) the TwinFrozr II, get the MSi, that's a lil bish


But I'd reseat the cooler, I've read that the thermal paste used on it is a bit... bad.

I've got the RMA set up for the Biostar refund.

I went with the MSI AMD 6870 Twin Frozr II non-reference card for many reasons. It was a toss up with non-reference Nvidia GTX 470. I gave it a lot of thought and read a lot of reviews by websites and users. Though the GTX 470 is better by a slim margin it was a personal decision.

The AMD is less heat happy and power hungry. I'm ok with a few less FPS, beside two AMD 6870's stock is just a tad betster than one Nvidia GTX 580 stock and I'm great with that. I'll be less worried about heat and power when I OC my AMD's too.

I was about to purchase Sapphire instead, actually had it ordered, when I started this thread but was able to cancel it after doing homework. Sapphire are the most common card out there for AMD's/ATI's and most popular. Way more often than not Sapphire had great reviews by users. There were other good choices like XFX which I gave some consideration but Sapphire would have been my secon choice with XFX following.

The non-reference MSI card however with Twin Frozr II fans and it's heat pipes made me drool. The Twin Frozr II was great even on the GTX 470 too. All solid state caps made it a clear winner. What a great card to OC, more stable and cooler than any other manufacturer offered. It's definitely worth the extra green for a clearly better built product.

I would suggest MSI's AMD 6870 or 6850 Twin Frozr II card to others who don't mind paying a little more for better quality and longevity.

Thanks again for the previous responses.
