Expert Advice on 980X Requested

[veblen]

Hello all, I'm an enthusiast bencher with two 980Xs and am deciding which one to keep.

 

The batch numbers are:

 

1. 3008A515T

2. 3005F729

 

I haven't been able to find much information about the first one (with the T at the end) save one submission here:

I'm thinking of finally going sub-zero next year but as of now, I'm not sure how to find out which chip is the better clocker.

 

Both chips can hit 4.25GHz (170x25) with mem at 1020MHz 9-11-9-27, QPI 3.6GHz with 1.3vcore.

 

I'd greatly appreciate any help here from the expert benchers!

4.25g is nothing...

 

try 5ghz with low mem multi... adjust vcore accordingly

I'd personally keep the 3005F as those have proven to be the better overclockers.

Thanks for the responses!

 

@Honda: I've been trying to get both to 5GHz (167x30), mem at 1670MHz but so far, no luck at up to 1.55vcore/1.4vtt/1.86pll/1.28 qpi. I keep getting BCCode 135 which doesn't seem to turn up on searches so far. The best I've gotten is 4.93GHz and the A515T seems to require lower volts than the F729.

 

I'm under water so I'm not sure how high I ought to push vcore.

 

@Sam OCX: Thanks! I initially leaned towards the F batch, esp. given the performance of 3005F720. But I have the F729 which is less well-documented, and the single screenshot of 6.3GHz on the T is giving me pause.

 

Will keep trying.
