Maximum overclock for a Sapphire HD7950 Vapor-X - Page 4

post #31 of 61
Cool, could you see any part numbers to see what the chips are rated at? I will assume mine has the same memory.

People people! Can you check this out? So someone told that it lies in the fact that MSI afterburner doesn't support it yet and Trixxx allows voltage OC. So I downloaded it and scrolled down and saw this?
Is this the voltage ? Please say it is, this finally means that I can OC it !

this^ im goin to try this on my HD 7950 Sapphire that seems having a low score on my heaven benchmark....... it seems the card is throttling on benchmark and need to be feed an additional small adjustment on voltage settings..... and hope so im not one of the guy out there with the voltage lock GPU...... smile.gif

No. Just took a quick peak.


Hope to have time to try it out soon. Have another build for a friend going on right now so my build is on break for a few days.

Well I tried Trixx and it didn't work frown.gif. Had the voltage at 1150 but GPU-Z says it runs at 1,100 and won't go higher.

So my friend Stefan has the MSI TFIII and he got the card to 1300 and 1600mhz. Is there no way I can get this?

Well I tried and put the voltage at 1130 (1125 stock) and the core clock at 1100 and memory at 1510. It ran good during Furmark but when I close the program I got a white screen.
Someone able to help me?

Overclock stable: 1190 core/1400 memory on boost bios. This was with Trixx 4.3.0, however I updated to 4.6 and It changed the voltage display. At default settings the voltage use to be 1125 and now it is 1250. Anyone know why that is because I am really confused about this? Also can't increase the voltages past 1300 now.

Things you should know before you Overclock this card.
What i found is:
299-2E210-201SA only has Hynix , 015.025.000.001.000000 Uses Stock V1.5
299-2E210-204SA only has Elpida , 015.025.000.099.000000 Uses Stock V1.6 What ever you do NEVER Mix these 2 bioses in order to FLASH them if you do you LOST your video card.

Now since i have the 204SA
i'll explain a few basic things

if you look over at http://www.elpida.com/pdfs/E1864E10.pdf their Data sheet from the GDDR5 2gbits you see that the Vram requires V1.6 and is capable of 6.0GBS i am talking about the EDW2032BBBG-60-F since that is the one that is found on the Sapphire 7950 Vapor-x.

So Keep in mind that the memory voltage should not go over V1.648 Anything above that will destroy them.
Also 98 °C should be considered the maximum.

With Trixx 4.6.0 i was able to reach 1200mhz and 1500mhz Easily as stable "game-able" clock VDDC set to 1225. only on heaven benchmark 4.0 could i find several Extremely minor artifacts which indicates that i should fiddle a bit more with the VDDC either forward of backwards still figuring it out.
However 1250mhz core 1450mhz memory vddc 1231 seems to run even better.

Temperatures?
on Idle
GPU: 29°C
VRMC1: 29°C
VRMC2: 32°C

I bought the Arctic accelero 7970 because the Vapor-x is Extremely noisy.
Even with 100% fan speed you barely hear it inside your case, it is a real work of art.
also with the Arctic aftermarket cooling package you get individual aluminum cooling blocks that you can glue with a special thermal glue in between.

Uder full load with a 1250 mhz Vddc over 1231 and 1450 memory
GPU: 55 °C
VRMC1: 70°C
VRMC2: 71°C


When it comes to Overclocking you should never compare, but just in case if you really wish to know
Asic: 71.3%
P/N: 299-2E210-204SA
V.Bios: 015.025.000.099.000000
Bios P/N: 113-210PBBBG-V08


Utilities used:
Trixx 4.6.0
Gpu-z 0.6.9

Testing applications:
Msi Kombustor 2.5 (burn-in)
Heaven benchmark 4.0
3DMark
3D Mark 11
Battlefield 3

Good luck with your overclocking!
Keep in mind that passing the 1.2 vddc your card will throttle (this is done by DESIGN nothing we can do about it). it runs okay but once every 6 hours you need to shut the the 3D application so your card and rest in idle for about 1 minute.
if you pass by the 6 hours of throttling you will notice milliseconds of freezing time that's all it will build up and can be very annoying.

Some tips?
I strongly recommend to remove the thermal tape from your GPU from stock coolers and replace it with aftermarket equipment.
The thermal tape provided runs your STOCK Vapor-x cools VRM 100 °C under loads this can permanently damage your memory once you start seeing discolored pixels or screen flickering try to refund your card as soon as possible.

I normally never post on forums or websites but since there is a "lack of knowledge" i decided to post some additional information.

hhhmmm????

Thanks for taking the time to posts but I am not certain what you are posting is correct.


VRM temps of 100C is not going to permanently damage the card and voltage of 1.2vddc is not very high. This card will shut off if the heat or voltage gets out of hand before the card is ruined.


I think problems with this card are BIOS related and once Sapphire gets a working BIOS for it should work better.

Elpida memory is design to go no higher then 98°C as shown on the Data sheet.
and on the Boost stock bios from sapphire the memory reach average of 70°C under full load so once you start overclocking you can easily reach 100°C this will cause permanent damage according to its creators. and Temperature can cause artifacts as well. so if your going to argue about that or not you might what to take that up to the creators and not post it here.

I'm just showing the data that we can find and work off with, anyone going over the suggested limits will eventually reduce the life time of the card by a much greater scale then when people read how things work.

increase of voltage increases the over all heat.
And considering the card uses 1.087 stock voltage on 100% load then 1.200 is a big increase.

what always is a big issue is the lack of information about the video cards/ graphic cards, i would much more prefer a full data sheet of the pcb with each module/chip explained in full detail.

The Sapphire HD 7950 Vapor-X 3GB OC boost has as far as i am aware off 3 different P/n's

299-2E210-104SA Hynix
299-2E210-201SA Hynix Bios updated: https://www.facebook.com/photo.php?fbid=10151220018934430&set=a.137560919429.107699.135403179429&type=1&theater
299-2E210-204SA Elpida

And as far as i am aware they are all working bios's.
it is the parts that are on the Pcb that determ the overclocking abilities of your Video/Graphic's card Hench Hynix has no issues getting above 1600mhz while Elpida is impossible to run stable at 1501mhz
