You never cease to amaze Mr. Fox! Now that I am not as mobile I might look into this, especially if 780M SLI is in my future. Keep up the good work.

Yes please, considering the upgrade at the moment, SLV7 has made it difficult to resist, will donate if I do.

I wanted to clarify where I am at performance wise: Same benchmark settings as your last, SSAA off, Vsync on, 1920x1080, Quality: Very High, Advanced Physics On, Tesselation: High, AF 16x: 51 FPS average 150 max. When I first played the game I had SSAA at 2x but there is significant stutter, and my rig is not anemic by any means (47k GPU 3DMarkVantage). If youre enjoying SSAA 2x without stutter then yes Titan SLI is monstrous. Isn't one Titan basically a stronger GTX 690, which itself is basically 680 SLI? So basically youre 680x4? Yeah I bet 2x SSAA looks amazing on a larger monitor! Unfortunately I am limited to the 18" that my M18x R2 is equipped with.

Your rig is a beast! Titan SLI! I get what you get with the same settings but lower resolution (1920 vs. 2560) http://file:///C:/Users/Vulcan/Documents/4A%20Games/Metro%20LL/Benchmark/2013.05.20%2011-14-20/metro_report.html Also, it doesn't indicate in the benchmark result but I had Tesselation set to "Very High". M18x R2 - 3920@ 4.4 Ghz, 680 SLI +200/+400 @ 1.0V=47k GPU 3DMarkVantage (need to update my signature here) Some observations of mine (same user name in the following thread): Metro: Last Light Performance - Page 3

I also posted this over in NBR: Sorry to interrupt here, I have begun to adjust some settings with ThrotteStop, mainly using this guide for reference, yet I am confused as to the max TDP/TDC or wattage that can be safely applied. I assume that 100-120 W would be about as most you would want to go and not have thermal shut downs yet in ThrottleStop under TPL/Power Limits the default is currently at 300 W (Power Package Limit). Now, I believe this is because I have made some recommended changes via the modified A05 BIOS a while back that unlocked the long limit duration among other things, but should I turn this down? Thanks in advance.

I posted this elsewhere but I want to repost it here so it will get more attention: So I finally ran wprime 1.55, apparently its 1024M is more rigorous than its newer version 2.04. Originally using a 26 multiplier and TDC/TDP 90/75 via throttlestop as thats what was possible using wprime 2.04, I got BSOD using wprime 1.55 with 8 threads going. I reduced the multiplier to 25 and it passed wprime 1.55's 1024M test in 285.63 seconds with a max CPU temperature of 97 C. I havent increased the voltage or overclocking in BIOS, also the DDR3 voltage is at 1.5. I tried a combination of 3% BIOS OC, 75 mV, and a 25 multiplier TDP/TDC 90/75 and got BSOD in wprime 1.55. But not only that, the reported speed in CPU'z and throttle stop was fluctuating wildly, dropping as low as 900 Hz, and the FID was scaling back significantly as well. With just throttle stop and no BIOS OC or additional voltage, the reported speed is much more stable, fluctuating between 3.1 and 3.3 Mhz and the FID only scales back to low 24's (25x). With the GPU's, I got BSOD running 825/1200 in Furmark under a stability test. I went with an 825/1150 which passed Furmark with flying colors but had Crysis 2 freeze up on me, Im not sure if its throttlestop or the overclocked cards or whether they are now both competing for a limited amount of incoming wattage that is culprit. I reflashed the cards to 800/1100 and will run a stress test with Crysis 2, fingers crossed. I think with the cards moderately overclocked and throttlestop also drawing more current, the problem may be a power supply issue, not in that the power supply is faulty, its just that the increased demand isnt something it can accommodate. Im not shooting for a bench OC, I am trying to attain a solid, everyday use OC as high as possible but keeping the CPU temperatures in the mid 90's and the GPU temperatures in the low 80's. It seems that its only with wprime 1.55 that I get such high temps. While playing Crysis 2 the CPU was in the low 80's, with the GPU's around 72 and 74.

Thanks for the reply. Well I did it! I had great success with a 800/1100 OC flash. Monitoring in Furmark the temps were 77 and 83 after 10 minutes. I am concerned as to why there is such a big temperature difference. Is this typical? I tried an 825/1200 flash but had the AMD drivers fail in a stability run in Furmark. What voltage should I be running at 825/1200? Ive done the retention mod as well, using Shin Etsu X23 and Tuniq MX-3. How much longer can I use x26 TDP/TDC 90/75? I havent had any issues yet, I attempted to monitor with wprime but I have version 2.04, I suppose I need ver. 1.55? In the bench on throttlestop the FID did not back off from 26. The 1024M run time was 371. or so, I know its not the greatest. Would I get better performance with 3% OC, 75 mV and x25 over 0 OC, standard voltage and x26 multiplier? What voltage increase should I use for the 825/1200 settings on the GPU's? Is there a better GPU OC setting you can recommend? I may just go back to the 800/1100 as it was stable with that setting, Im not comfortable with playing around with the voltage until I get an idea of what safe amounts others are using.

Hi everyone on techinferno, Unclewebb told me this is THE PLACE for Alienware enthusiasts. I have an M17x R2 with an i7 920xm, 6 GB RAM, and an X-fire set up. I have had some success with throttlestop, my present settings are TDP/TDC 90/75 with a 26 multiplier, no BIOS OC, default voltage. I want to flash my cards with a value that wont compete with the CPU for juice as I believe some values will do this. Is 800/1100 a good value? What about voltage? I assume the instructions in the following links which were originally for 4870 cards are applicable to the 5870's? Are these the best, recent instructions to use?
