How do you make that tri-bench image, side-by-side, including the bottom text? Is there some function in AIDA that can do that? Or are you doing it manually in Photoshop, for example?

Just print screen and ms paint. Then organize and add text.

Kahboom looks like 45 is good for 1600mhz at stock voltage. Getting 700MH/s solid at 1125/1600. I'm gonna go oit on a limb and say that this is optimal overclock on stock voltage. At this point the core speed is holding back the hash rate but at stock voltage core can't go very much higher. Looks like you have found the best timming to allow more bandwidth. I think if we go looser to support 1700 mhz well loose speed for bandwidth which would be counter productive.

How are temps? Let me know how stable it is when you do more testing.

Temps are great less than 80C without box fan. Box fan drops it to sub 70C. Mined for 4 hrs just fine. Played d3 for a couple hrs fine. Gotta try ff14 still.

FF14 played flawlessly at 1150/1605 @ 1.258V. I bumped the core voltage a bit to see it I can get the core to 1200Mhz. Temps still great.

Gonna keep memory at 1605 and see how far I can push core. 1200Mhz now is stable with 1.258V

I posted this question in R9 2XX owners thread, but it seems that here is more appropriate to ask.

I have MSI R9 270X Gaming, and I just want to know, is it possible to edit and flash BIOS by myself, only with new fan profile?

Can I do that with VBE7 and what about this warning:
"Modifications only affect the legacy BIOS, and after saving, UEFI image will be disabled (in case you have UEFI vBIOS)"

Please, can someone explain to me this legacy/UEFI BIOS warning?
VBE7 is not officialy support R9 cards, but R9 270/280/290 are same cards like HD 7870/7950/7970

The warning is it disables the uefi in the cards bios. Uefi supports fast boot, legacy does not. Uefi supports large hard drives over 2.2tb with the is installed on it and higher for the future. Uefi is gpt partition plus efi plus mbr since it supports fast boot and supports legacy devices. Standard windows I just mbr . It will disable the gpu s ability to fast boot into an os that's basically it. If you have an ssd and you system is over clocked. Its such a minor difference. Nothing to really worry about till hard drives get far larger. Uefi is set to replace the legacy but will not fully change over for a good number of years. But its still backwards compatible with legacy cards if you have windows 8+

Hello guys. Im new to this forum and i just bought the 7950 vapor-x OC version.

My question is my gc is running at 1125/1350 at 1.15v/1.60mv. Every time i try to increase the core clock to 1150 or 1200 the game crashes and the driver stop responding and return to the desktop. I did try increase the voltage to 1.2v or 1.25v. But i still cant.

the weird thing is even at 1125/1350 at 1.15v/1.6mv its very stable. I play metro last light like 6 hours. doesnt crash at all. Even if i increase the memory clock to 1375 the computer crash and i have to do hard reset.

and i got confuse when i play metro last light, vddc hover between 1.08v to 1.09v. at 1125/1350. Im pretty sure its not my cpu because i ran prime95 for 12hours.

My rest of the rig is :

AMD A8 5600K Oc to 4.20GHz
Gigabyte GA-F2A55M-HD2
4GB Kingston genesis Oc to 1866mhz
Cooler Master 550 Extreme Power Plus
7950 Vapor-x oc 1125/1350

VRM around 83c and gpu temp around 76c. but if i increase the voltage to 1.2 or 1.25v it can easily get to 80c and vrm around 90c.

I hope my psu is the problem.

thanks in advance.

thanks in advance.

may i suggest oc'ing the cpu more instead. i remember not being able to play BF3 smoothly with a 7950 if my i7 was at stock. 4.5GHz did the trick. so, if you are trying to get more fps, you should focus on your cpu.2cents.gif

i wonder how an APU compares to an old Phenom . . .

Im not sure thats the case. but i can play metro last light smoothly around 40-60fps at 1080p. may drop to 30ish.. but ssaa turned off.

i dont have bf3 at the moment but i'll try bf4 tomorrow and report back.

any insight why my 7950 cant get past 1125 even at 1.25v. is it silicon lottery? if so, i might deal with it. just had to make sure if anything is up with the rest of my rig though.

my asic quality is 80.1%.

i checked the review that my psu is totally suck.
