i dont like vertically mounted mobos though lol
sagging gpus and all that...

Blocks of wood cut to size work great

YOUR BASKET
1 x Lian Li PC-V358B Micro-ATX Cube - Black £129.95
Total : £129.95 (includes shipping : FREE).



this case takes my fancy at the moment, definite support for 240mm thin rad, if the front can fit another 240mm rad without much modding, i think this'll be my next case

nice, but not much rad space.

I was running my CPU and 1x7990 with a normal width 360 and 240 rad and was getting about 60 degrees if I ran GPU's 100% for about 10 mins with bitcoin mining. Under benches like heaven, about 55

max fan speeds?

Anyone?? You guys using Asus GPU Tweak instead of MSI Afterburner?

 

[daveip]

damn. that's some pretty good clocks. i hope mine's like that lol
and that's your heating for the winter...

I could get 1225 when I pushed the vCore to 1.3V, but figured the difference in vCore to get to 1225 from 1185 wasn't needed.

Need to get this thing under water!

nah AB is the best.

For benching I use 1.3v under water, normally for games I run stock, but I do have 2 of them under water.

Anyone else having issues with BF4? Mine seems to be crashing with out of memory errors after about 5 minutes. When I check afterburner it's showing gpu memory usage @ 3500mb.

This is at 1080p Ultra settings, that can't be right...is there a memory leak?

Have u got the latest catalyst drivers ?

Are u overclocked, if so reduce oc on memory

Yep 13.11 beta 8

How did you get your mem to clock past 1575? That's the highest the slider would go for me in AB. + no mem voltage

1725 under water is my max. Can't change mem voltage yet. Read my lists above, go to ab settings and tick official overclocks. Make sure on latest ab

Just got my new 7990 yesterday and it's a bit quick but should there have been a AMD gold ticket in the box? there wasn't in mine and I haven't received it by email either.

Thanks

Seems i cant take the core past 1100 without it locking up in 3dmark...Managed to take the memory to 1650 though on default voltage and could probably take it further. Seems like a good overclock overall.

 

[SuperCurro]

Someone has this problema on w7?
How much fps do you get on uh4.0 w7 without oc?

Thanks

Hello

We have a long threat about this issue in Spain

Please use Google translation

Look at the graphs.





Our preliminary conclusions is that the power fase are insufficient so the card has to regulate it self. In w8 it does OK but in w7 doesn't. So if your voltage is lower than 11.5 V de load will drop in w7 from 98 to 60 % jumping all the time and in w8 to a constant 92%.

The only solution to get the best of 7990 is a gold power supply higher than 800w with w8 and power limit +20%.

Do you have the same experience or the 7990 series that have been sold in Spain are wrong?

Thanks

Now bang up the voltage

So chaps how are you all finding the 7990 ? Are you all happy with it ? I know some of you came from a GTX780. Are there any major problems with any games you play etc ?

 

[Catanonia]

Loving mine, but I bought one of the 1st from OCUK.
