I'm up to 925 core on 1.25v

 

[stefk005]

925/1200 @ 1.23... However I seem to be bottlenecked by my E7200 @ 3.35 - anyone have something similar? Uniengine score went up with the OC, but not Crysis. Notching the CPU up to 3.41 got a couple more fps in Crysis...

 

[sHo0sH]

900/1200 here @ 1.2 - need to try a proper burn in but 10 minutes on Furmark with no errors and 72c max isnt too bad

 

[Andy__C]

What kinda scores are you guys getting with the clocks in Uniengine Heaven?

Would be interested to see how they are comparing with everyone at these clocks.

I've gone as far as 920 running the benchmark scoring 821 - using the parameters given in the Uniengine thread.

 

[sHo0sH]

I got 820 running stock speeds, Was going to try the unigine heaven again later with the OC speeds.

Rest of my system is i7 920 stock, Unigine is installed on Vertex 2e SSD, with 6gb Corsair xms 1600mhz

If you got a good CPU cooler, your board should be able to clock your E7200 up to 3.8-4.0GHz...which WILL give you a couple more fps in Crysis.

@925/1200, uniengine score is 1011 with those parameters, except my display is 1400x900.
@stock, score is 823.

sHo0sH, 10 mins of furmark doesn't seem to cut it for me - mine was stable for 20mins and then crashed in uniengine.

I'll give it a proper burn in this evening, and will post back with my findings, fingers crossed I'll break a thousand

sHo0sH, 10 mins of furmark doesn't seem to cut it for me - mine was stable for 20mins and then crashed in uniengine.

I did the same test procedure, first Furmark run for 20mins at least then looping Unigine Heaven for half an hour. Doing so I thought I reached stable 940/1225 @1.225v, but when I started testing the OC in games such as Crysis, NFS Shift and Mass Effect it crashed after some time. It seems that Furmark and U.Heaven only aren't enough to test if the OC is stable. I had to lower the core at 920 to get it stable in gaming.

Very impressed by this card, I upgraded from a 4870 and the difference is night and day. The card is very good in 1080p with Crysis 2 and Dawn Of War Retribution, it is a shame that there is only 1 DVI port but you cant have everything.

The card also runs very cool and very quiet, rare things in PC gaming these days.

There is a 2D Power saving bug in the drivers/BIOS which prevents this card from working in my PC at stock settings, which is reproducable.

The bug is reproducable with Cat 10.10e and 11.4.

I got around it by placing a 3d application into my start folder, minimising it and overclocking the card (sic), giving it some extra voltage in the process, using the Sapphire utility. Stable as a rock so far.

Thanks OCUK and Sapphire for this great deal.

Thanatos, seeing as you've got a C2D @ 3.2 was wondering if you saw any increase in scores/frames thru oc'ing the card? If my experience isn't anomalous somehow you should be bottle-necked by your cpu...

i ran furmark for 20 mins gets it warm then played games for couple of hours

no artifacting

what safe limits on these cards ?

Question for when my 2 5850s come:

Is the correct procedure to install the cards:

remove drivers of old card > remove old card > fit both cards in > install crossfire bridge on them > boot up the pc and install the latest drivers from the amd site

Which drivers do I use? I've seen a few posts where people talk about application profiles and that?

 

[sHo0sH]

I tried putting mine in without uninstalling drivers first - didnt work.
I then unininstalled them from Win7 Control panel, reinstalled and its been working fine so far. The drivers I'm using are 10.14 I believe.

 

[sHo0sH]

So after a run at 900/1200 I am getting a Unigine score of 878, average of 34.9 fps min 18.1 fps and max 85.4

Anyone else care to share their findings?

In fact, yes I did see an increase in frames even if I got a "low" c2d Eventhough the CPU bottlenecking the GPU -for sure- I still saw difference in the games I tested it with and in the benchmarking programs; and bear in mind also that I run on a P35 based mobo which means PCIe v1.1 (less bandwidth) and for that reason I lose a couple of extra frames in some specific games as well.

FYI my (GPU) scores in Vantage so far:
1. 5850 @stock = 14522
2. 5850 @825/1225 (no extra voltage) = 16364
3. 5850 @940/1225 (@1.225v) = 17467

I had an NVIDIA 8800 GTS before and I used a program to clean everything from its drivers before installing my 5850. The program is called Driver Sweeper and you can check it right here: http://www.phyxion.net/Driver-Sweeper/Driver-Sweeper/

First uninstall all old drivers with it then install the Graphic Cards in your PC.

Can you please explain what kind of bug this is and how did you get around it? I use the latest Cat 11.4 (Win7 x64) and havent experienced any bug yet.

I got a 19" lcd monitor so I run Heaven at 1280x1024. With the 5850 oc'ed 920/1225 @1.225v and stock settings in Unigine Heaven 2.5 I got a score of 1205 (FPS min: 19,4 max: 123 and avg: 47,8).

does ocuk sell the crossfire bridges? i have tried looking but cant find any.
