SAR Posted December 30, 2006 Share Posted December 30, 2006 These are my old box specs. PLEASE read my last reply. Original old specs: OS: XP Pro SP2 Mainboard: Abit KN8 SLI CPU: Opteron 150 HSF: Thermaltake Silent 939 K8 HSF HDD: WD Raptor 150 (ADFD) PSU: Corsair HX520W CASE: Coolermaster Praetorian 730 RAM: 2GB EL DDR PC-3200 Video: eVGA (x2) 7950 GT KO 512MB Sound: X-FI XtremeMusic Monitor: NEC 20WMGX2 Keyboard: Saitek Eclipse Mouse: Logitech MX-518 THANKS Link to comment Share on other sites More sharing options...
SAR Posted January 1, 2007 Author Share Posted January 1, 2007 Can someone please answer this? All I really want to know is if the Corsair HX520W is ok for my specs? THANKS Link to comment Share on other sites More sharing options...
DerekT Posted January 1, 2007 Share Posted January 1, 2007 The minimum would be a 500 Watt Power Supply with two of these cards. Keep in mind that Raptors are also quite a bit more power hungry than the average 7,200 rpm hard drives. Is the Opteron 150 overclocked? If so, what is the FSB and Clockspeed as well as the core voltage of the system? There is a condition called "Threshold Voltage" which is the amount of power necessary to turn on and switch the transistors gates and which increases vastly with overclocking and especially so with CPU core voltage raises. There is a formula for the switching power: Power ~ ½ CV ² Af This formula states that dissipated power is linear with the effective capacitance, activity and frequency. Power increases quadratically with the CPU's core voltage. Thus when you overclock you are increasing the necessary voltage by a multiple of four and the voltage effects are not linear but multiplicative, and exponential. So minimums are not a good practice to follow as it is is very necessary for a strongly functioning power source to supply the overclocking needs. Did you remove the drivers and reinstall new ones with the new graphics adapter? Try driver cleaner from http://www.driverheaven.net Link to comment Share on other sites More sharing options...
SAR Posted January 1, 2007 Author Share Posted January 1, 2007 Well I've been playing with a OC on the Opty, but it looks like I have a crap stepping and can only get around 2.66ghz out of it. I'm playing with it around these settings: FSB: 250 Multi 10x Dram: DDR333 Volts: 1.48-1.52 THANKS Link to comment Share on other sites More sharing options...
DerekT Posted January 1, 2007 Share Posted January 1, 2007 Here's a test to see if it is the PSU. Remove the overclock. Play the games. Yes, they will be slower due to the removal of the overclock, but the "lag" you are experiencing is more attributable to power or driver issues. Lower FPS is more attributable to GPU/CPU clocking issues so don't worry about the lower FPS. Is the lag still there? Link to comment Share on other sites More sharing options...

DerekT Posted January 1, 2007 Share Posted January 1, 2007 I would remove the drivers, use driver cleaner to remove the driver remnants and reinstall the newest drivers and retest. Link to comment Share on other sites More sharing options...

DerekT Posted January 1, 2007 Share Posted January 1, 2007 I ran F.E.A.R. with two 7800GTX 512's in SLi and at 1600 there was no lag that I could see. Only 1280 with my current 7900GTX though. But then I have a Core 2 running at 3.4Ghz and DDR2 @ 3 - 3 - 3 - 9 Link to comment Share on other sites More sharing options...
SAR Posted January 2, 2007 Author Share Posted January 2, 2007 Well you have Core2 and DDR2. I'm running single core and DDR 3200 Guess it's going to be time to get a dual core at least, maybe a Opty one. THANKS Link to comment Share on other sites More sharing options...
Lenny_Nero Posted January 2, 2007 Share Posted January 2, 2007 Is F.E.A.R. dual/multi threaded ? What else have you got running, and going on in the background while playing ? I have just sorted a friends brand new box that was slower than my Asus (his was just got and running a core duo) much slower, but it was just that the box was so loaded up with junk TBH nothing much stood a chance. Task manager was about 4 pages deep at boot ! Indexing costs about 5~10% and most users will never need it, there are also a lot of other things that just cost clock cycles and never get used, but you do say that running one card is better than two ?

DerekT Posted January 2, 2007 Share Posted January 2, 2007 Is F.E.A.R. dual/multi threaded ? No, but the difference between an Opteron 150 and a Core2 at 3.4Ghz is quite marked regardless of the single core vs dual core. Link to comment Share on other sites More sharing options...

SAR Posted January 2, 2007 Author Share Posted January 2, 2007 Lenny_Nero this is a GAMING only box, I have it stripped to the bone. I don't use game IMs like Xfire, or have anything running in the background except NOD32. My box is the epitome of clean and lean, LOL :cool: I'm a geek and I know how to strip and run XP, so that's not my problem. ;): Ok so BOSS man gave me the thumbs up on the PSU, so it's down to the CPU, Vid cards, drivers.... Personally the way I see the latest 90x drivers these things have been pretty bad, and also I get the feeling the SLI support might not be the hottest for the 7950 cards too. At this point I'm more inclined to think the cards and drivers... Anyone else? THANKS Link to comment Share on other sites More sharing options...
SAR Posted January 15, 2007 Author Share Posted January 15, 2007 And Sar, Our HX520W will be pleanty for that configuration. My box specs have changed, highlighted in GREEN OS: XP Pro SP2 Mainboard: Abit KN8 SLI CPU: Opteron 165 HSF: Tuniq Tower 120 HDD: WD Raptor 150 (ADFD) PSU: Corsair HX520W CASE: Coolermaster Praetorian 730 RAM: 2GB EL DDR PC-3200 Video: eVGA (x2) 7950 GT KO 512MB Superclock Sound: X-FI XtremeMusic Monitor: NEC 20WMGX2 Keyboard: Saitek Eclipse Mouse: Logitech MX-518 I plan to really push the Opty 165 upwards to 2.8ghz at least, so do you guys think my specs are still ok for the Corsair HX520W? Evga says the min. for the 7950GT cards in SLI is 500W, I can't believe they use up all 500W, anyone know some facts on this the actual amount they'll use, and if I have much left over with these specs?

NO Garvin, all I wanted to know NOW is if the Corsair HX520W is fine for my specs, that's all. :) And from what I've read and seen so far it is.
