ATI 4850/4870 voltmod thread

[vengance_01]

Hate to burst your bubble, but here's the fact about what you're saying:

Best Buy 4850 = $199 + Tax (Maybe 10% off, Saving Tax)
VF-900 = $30-$35

So we're at about $240 for the retail 4850 w/ VF900. Now, the 4870 is $299, and can clock without mods to at least 790 on the core...

After modding 3 4850s, the best core @ 1.4v on an Accelero S1 was only 820 for me... All of my Visionteks were duds, I guess... I also hate to tell you that your VF900 will be overwhelmed after 1.35v on the VGPU, netting you an average of 810 on the core.

I posted my results of the vmodded 4850s vs the 4870s, and there was still over 10% of a difference in favor of the 4870...

Also, the volt mod will be available soon for the 4870, and the stock cooler may actually be able to handle a bit more voltage. I'm loading up at 48C on 1.3v, stock coolers, in CFx.

So really, it's up to you, but it's not a HUGE price difference, and the 4870 is still on top no matter how you slice it.

hum... Well I already have the Zalman VF-900. If Bestbuy has the 4870 I might get that, but there are currently 0 volt mods for the 4870's. Also what were your temps at 1.4 volts? These cards seem to take the heat well. Also the 4850@800 core and maybe 1200 memory is still a fast card. Also I am not looking for top performance, but bang for my buck and thats where I see the 4850. I guess lastly it will be more fun to bench the 4850 then the 4870. Not in terms of score, but fun in general. =)
