possible bottleneck ? & HD3870x2 switches

post #1 of 12
Thread Starter 
ok m running a Athlon II X4 640 and i am also running a HD3870x2 1GB
CPU OC @3.6
GPU OC @ 900/1000 C/M
im using MSI afterburner for GPU as im using 2x6pin pcie connectors so cant use CCC to OC

can any one see a possible bottleneck in this setup

side note also i noticed there are 2 switches on the back of the card what are they for i cant find any info online about them

I don't see how there could be a bottleneck. If anything your GPU is going to limit what your CPU can handle.

I've got this exact same card.

It's in it's box buried deep in my wardrobe, and likely will never see daylight again (Terrible card, regretted ever purchasing it, esp after the cooler packed up - very difficult to find replacements for)

I recall asking the same question about the switches, you'll find that thread here:

Hope that helps.

3870s are not fast enough to be bottlenecked.

really? £160? thats really steep. I could get another 6870 for that price.

Pity i have no cooler on my old 3870x2 otherwise i'd sell it, at least it would be put to better use.

I had nothing but problem when i purchased it new several years back on release. The crossfire was buggy and performance was dreadful, perhaps the creases have been ironed out sinse then but i have no intentions of ever using it again.

It pretty much put me right off multi-GPU setups.

yes that much the link works but the one that has info on the switches dont guess i will never know i might be able to buy a faulty HD3870 x 2 to replace that faulty cooler of yours how much would you sell the card for
