HD 2900 Series Overclocking and Feedback thread

6 Pin vs. 8 Pin

Not sure if this has already been pointed out:

"... Here's a look at the funky eight-pin power plug on the 2900 XT. This plug will accept a six-pin connector, but AMD's Overdrive overclocking utility isn't available unless an eight-pin power plug is connected. I've never seen an adapter to covert another connector type to an eight-pin one, either, so you're probably looking at a power supply upgrade if you want to overclock this card. ..."

How about other OC'ing utilities working with 2 6Pin connectors?

Sheer genius.

WHy thank you sir

This mod is so easy.....everyone with this card should do it. Sure everyone has two extra motherboard riser screws....and access to a hardware store such as Lowe's or Home Despot (er.....Depot

)

Well, there is an adapter, but it's only necessary if you plan to use Overdrive to OC. (Even then, it's not 100% necessary, you only need to rig up a negative to one of the empty pins) ATITool and AMD GPU Clock Tool will both OC with 2 6 pins.

After performing my fan mod, I can run 843/2250 stable 24/7. I've played Crysis beta for over an hour using this OC, and the memory is only warm to the touch, when it used to be SCORCHING hot, almost enough to burn my fingers. The GPU brace was really hot as well, but now it's just BARELY warm.

bassmasta · Oct 7, 2007

how are you guys getting these huge oc's? I can run 790/832 before I get artifacts out the flashpipe. fan's at 100% and I have air moving over my backplate, too.

I could get 820ish/950ish out of the box, but I had to use ATITool to bump the voltage for 847/999. I also have very, very good case airflow.

bassmasta · Oct 7, 2007

I would consider my case airflow to be paranoid, but I read that ati gpu tool adjusts voltage automatically.

No, GPU Clock Tool does not. I think overdrive might tho.

What application are you OCing with? Operating system? THat's one badass OC man....I'm jealous. I got a driver lockup at 2200 today, but last night I could play all night. Well I'm thinking that the memory is getting too hot on the back, so I'm going to put a fan on it or something.....

im just using amd GPU clock tool, and on vista ultimate. cant access voltages so all is on stock at the moment, tho im using a DD-29XT full coverage waterblock (look on the reviews page)

tho... my rad is quite insanely large :roll:

actually, i had a load of pics i was gonna post as a project but its far too late... i had to mod my case etc and had loads of pics of my cooling setup for my 2900xt

i wanna have voltage adjustments too!

Well I'm running 843/2250 now with my fan mod. W00t! Totally stable, been playing Crysis at this clock everyday for up to an hour or more at a time.

And how does Crysis run on it? Just curious.

binormalkilla · Oct 9, 2007

Runs great. I'm running it at 1920*1080......and I run it faster than 8800gtxs

I can't really say much due to NDA, but I've compared FPS to GTX owners and they're jealous!

Sweet. I understand about the NDA, but thats what I am talking about.

stinzza · Oct 11, 2007

yo.. gotta qestion.. how come the 8800gtx is faster ingame.. when 2900xt is better 3dmark. 2900xt has 8.0 size core and 8800gtx got 9.0.... what does 2900xt card uses the extra power usages for????????

Not all games

stinzza · Oct 11, 2007

well.. say 50-50.. so whats the extra power usages for..

stinzza · Oct 11, 2007

if you ask me.. maby nvidia has found a shourter way for the wires on the card but in a tighter way.. so the bandwith is a bit lower....

cepoi · Oct 11, 2007

stinzza · Oct 11, 2007

aaa

or is it that the r600 core is higher clocked.. then again does not seem to enhanze gaming performance.. have someone tested if you downclock the 2900xt core to 8800gxt level.. does it draw the same power then??

I'm totally confused now lol

I love when people think that all cards are made by the same engineers
