I have a Reference 290X using Elpida VRAMs and I used the respective BIOS (mem modded one) but I wasn't able to break 1050Mhz on the core @ +100mV. Memory clocks were untouched at 1250Mhz.

On the contrary, the stock BIOS coupled with MSI AB V4.0.0 voltage tweak to 150mV yielded 1200Mhz on the core.

Lots of members here reporting a little lower clocks with the new bios. But if you run some benchmarks it seems the new bios provides more performance clock for clock

This modification is overclocking your memory in a way by tightening the timings. Your core clock to memory clock ratio is no longer the same. I'm sure you are already aware but on a stock card as you overclock the clock you must overclock the ram at a somewhat constant ratio that YOUR card likes different cards will have different ratios. This ratio is so important that say for example that a card could be unstable at 1050/1350 but stable at 1120/1374... make no sense at first until you read about this ratio theory. Well that ratio is BLOWN out the water by changing your timings... just like with your main system memory as you increase the speed of the memory you must loosen the timings.

I would venture to say that anyone who had an excellent core and memory clock figured out (one that was in the upper 90th percentile) probably won't see an increase in performance between these bioses but thats just a guess without looking into the data. Again though I'm saying people who really did the work or got lucky to nail their settings. I for one am someone who hasn't nailed their settings.

Anyways just trying to explain that in your case and the case of other people it is NO surprise that tighter timings = better performance per mhz.

Gentlemen, i have a Vapor-X 290x 8GB card. I WANT to help. What can i do?

Also is the consensus for Vapor cards ; to wait it out till a 390x Vapor-x is released?

As I understood only mod verssion mod timings, nomod verssion has stock timings and a little performance boost
post #555 of 1994
No, MOD version has modded voltages. Both MOD and NOMOD versions have modded memory timings and thus give slight performance increase.

successfully flashed my sapphire r9 290 vapor x oc with hynix modded rom from OP post.
did no benchmarks, my flash wos on purpose to fix my bf4 issue.
default rom:

modded rom

modded rom with slight oc

Well, I'd advise against that, because Vapor-X cards have custom PCB. It could destroy your card since VRMs are completely different.

Dear Mister Fyzzz, think we can get the latest version of your awesome bios? smile.gif Been seeing the benchmarks ... !

Well maybe. First the bios i made are very customized to fit just my card and I bet many cards can't handle it, but surely some can. Second my main computer will be down for a couple of weeks, so I can't upload the bios anyways. But I have to consider it when I get things running again.

The BIOS worked great on my card, it gets higher scores than my pre-overclocked original BIOS (vs stock 290X speeds of this BIOS) but somehow it really dislike I overclocked the memory even slightly. But overclocking memory gives little gain anyway so it's not a big loss. I get lower temps too, well maybe that's because I change the fan profile biggrin.gif
